Measuring device / DR. JOHANNES HEIDENHAIN GMBH In a measurement device for measuring the relative position of two objects, a scale (M1) is scanned by a scanner unit with a scanning plate (AP1) and a photocell plate (PP1). The scale (M1) has graduations (T) and identical reference marks (R1n) equispaced (spacing d) in the direction of measurement X and precisely coordinated with these graduations (T). On the scanning plate (AP1) there are two sets of reference scanning graduations (RAT1a, RAT1b) and on the photocell plate (PP1) two reference photocells (RP1a and RP1b) with the same mutual spacing (d). To select a reference mark (R1x) required for the measurement an ineffective reference mark (R1u) is provided adjacent to the latter. If two unselected reference marks (R1n-1, R1n) are scanned and one unselected reference mark (R1n) and the selected reference mark (R1x), two reference signals of opposite polarity are generated, additive superimposition of which produces a resultant reference signal that cannot be evaluated; only when the selected reference mark (R1x) and the ineffective reference mark (R1u) are scanned is a reference signal (RS1x) generated which gives a resultant reference signal (RRS1x) that can be evaluated. |

DGPS POSITION LOCATING SYSTEM / MITSUBISHI ELECTRIC CORP PROBLEM TO BE SOLVED: To obtain a DGPS position locating system which can compute a relative position while a moving station designated as a master station is used as a reference, by a method wherein position data whose time is identical for the masterstation and a slave station is used, the relative position is computed and the position of every mobile using the master station as a reference is displayed on a digital map.SOLUTION: By a computer 5 in a master station 2a, an input device 6 is used, and the master station 2a is set. Then the master station 2a executes a processing operation. When a GPS receiver 4 outputs an own position, the sampling time Tpand the position Pp(t) of the master station 2a are updated. Then the position Pp(t) is smoothing-processed, and a reference position Ps(t) is obtained. In addition, as data on the master station 2a, the reference position Ps(t), the position Pp(t), the sampling time Tpand a capturing satellite number SNp(t) are transmitted via a communication device 7. At the same time, a digital map is read out from an external storage device, and the computed position Ps(t) is displayed on the digital map as the position of the master station 2a. The communication device receives position data on a slave station 2b. When the sampling time Tcof the position data on the slave station 2b is equal to the time Tpof the master station 2a, the relative coordinates RPcof the slave station 2b is computed. |

PLASMA ETCHING APPARATUS / SUMITOMO METAL IND LTD (PURPOSE) To surely control an etching rate and to reduce a manufacturing cost by subjecting supply electric energy of a high-frequency to feedback control in such a manner that the peak-to-peak voltage value measured in a plasma etching apparatus attains the value approximate to a preset reference voltage value. (CONSTITUTION) A bias voltage Vdc is generated between a sample stage 26 and an etching sample 26a when a high-frequency voltage is impressed on an electrode 27a disposed at this sample stage 26 from a power source 17c in the plasma etching apparatus 10 having a microwave oscillator 24, a plasma forming chamber 22 and the etching sample 26a. Since there is a large correlative relation between this Vdc and the etching rate of the sample 26a, the peat- to-peak voltage Vpp having a proportional relation with the bias voltage Vdc is measured at all times by a matching box 17b of a high-frequency electric power supplying means 17. In such a case, the etching rate of the sample 26a is surely held at all times by previously setting a reference V'pp corresponding to the Vdc , comparing the Vpp with V'pp and adjusting the high-frequency supply electric power so as to approximate the Vpp to the V'pp . |

DESTATICIZING LIGHT CONTROL METHOD FOR ELECTROPHOTOGRAPHIC DEVICE / FUJITSU LTD (PURPOSE) To uniform the electrostatic potentials at all positions of a photosensitive drum and to prevent an irregularity in print density, fogging, and a decrease in resolution by detecting a printing medium passing an optical destaticizer and then projecting destaticizing light only when the printing medium shields the optical path of the destaticizing light from the optical destaticizer to the photosensitive drum. (CONSTITUTION) The recording medium PP conveyed from a hopper is detected when passing a medium sensor 8 and after the medium stops temporarily, a phase switching part 21 drives a stepping motor with a driving clock generated by a clock generator 20 on the arrival of a motor start signal. The medium PP is conveyed again by a conveyor roller 9 by this motor driving and the driving clock is counted by a 1st counter 31 and compared by a 1st comparator 33 with a 1st reference value 32, thereby outputting the distance A by which the medium PP passes the optical destaticizer 6 from the roll 9 to a lamp driving part 39. Similarly, the distance B by which the rear end of the medium PP processed by a counter 36, a comparator 38, etc., passes the optical destaticizer 6 from the roll 9 is applied to the driving part 29 to prevent the resolution from decreasing. |

PROTECTIVE CIRCUIT FOR THERMAL HEAD / TOSHIBA CORP (PURPOSE) To judge a condition to be abnormal and stop the suply of printing pulses or a driving power to a thermal head when a converted voltage exceeds a reference voltage, by a method wherein the pulse width and the pulse separation of printing pulses supplied to a thermal head are converted into voltages, and the voltages are compared with reference voltages. (CONSTITUTION) For example, where the printing pulses PP include pulses P1 having a width larger than a predetermined width, the charging voltage of an integrating circuit 52 is raised above the reference voltage VTH by the pulses P1 , as shown at (b) in the figure. Therefore, an output signal from a comparator 54 is brought to a low level in the condition wherein the charging voltage of a capacitor 522 is higher than the reference voltage VTH, as shown at (c) in the figure. As a result, a resetting output terminal Q of a flip-flop circuit 56 supplied with this signal is brought to a low level as shown at (d) in the figure, whereby a gate of an AND circuit 51 supplied with a signal from the circuit 56 is closed, and outputting of the printing pulses PP to the thermal head 11 is stopped, as shown at (e) in the figure. Accordingly, the thermal head 11 is prevented from being overloaded. |
