TONER FOR TONER JET / MINOLTA CO LTD PROBLEM TO BE SOLVED: To obtain a toner which does not cause clogging even when the toner charge level is rather high and with which excellent picture quality can be obtd. without causing trailing, splashing, decrease in sharpness, decrease in density or the like by controlling the AD value (loose bulk density) to a specified range. SOLUTION: This toner is used for a toner jet method by which the toner is directly sprayed and deposited on a recording body, and its AD value (loose bulk density) ranges 0.400 to 0.515 g/cc. If the AD value is less than 0.400 g/cc, the image density significantly decreases if only the toner charge level is controlled to be a little higher, and this significantly narrows the allowance for the setting conditions of the device. If the AD value exceeds 0.515 g/cc, pores of the recording electrode where the toner passes are clogged in a rather early stage of repeated printing, and the image density is easily decreased with a rather low charge level. In this case, the opening area of the pores is decreased by the influence of clogging and this makes passing of the flying toner difficult, so that the image density decreases when the charge level is rather low. |

FAULT DISCRIMINATING SYSTEM FOR INPUT AND OUTPUT CONTROLLER / HITACHI LTD (PURPOSE) To discriminate a faulty input/output controller, by displaying the faulty controller by a lamp and with the output of a flip-flop circuit which is provided at a fault discriminating circuit. (CONSTITUTION) A mode signal of a central controller CC, a data bus line 21 and a mode signal 22 of an input/output device IO are connected to the decoders 500, 501 and 502, respectively. FFs 515W518 are set based on the address of an input/output controller IOC given from the CC, the mode signal given from the CC and a transfer request signal given from each IOC. These FFs are then reset according to the end of the signal or the end of the received signal in the starting sequence of the CC. Then lamps 519W521 are lit up by the output of each FF. With such formation, a lmap corresponding to a faulty IOC is lit up. Thus the faulty IOC can be discriminated. |

PROCESSING SYSTEM FOR VECTOR INSTRUCTION / HITACHI LTD (PURPOSE) To eliminate the overhead that is produced when a conditional code CC is set in a post-process by setting the CC so far carried out while the post- process is carried out by a microprogram through an arithmetic operation of the 1st operand +0 performed by hardware before an operation. (CONSTITUTION) A control part worked with 4-phase clocks T0 WT4 and registers 510W518 are set with T1 together with registers 519 and 51A set with T2 respectively. A signal 53 is transmitted by designation for execution of an arithmetic operation. The signals 54 and 55 shows an execution signal and the secondary command of a vector instruction. While a signal 56 sets the secondary command to the register 514. The registers 510W513 show the arithmetic stages. The secondary command of the vector instruction is stored in the register 514 when the instruction is started. The secondary command is not changed at the register 514 until the next instruction is delivered and then turned into the control signal of an arithmetic part. The registers 518 and 515W517 are started before an operand designated by an instruction is calculated in an arithmetic stage of a dummy started when the vector instruction is started. A signal 58 serves as a set signal of a CC register. |
