Title: Image forming device
Inventor: YAGISHITA TAKAHIRO
IPC: G03G15/043
Filed: 1991-10-31
Abstract: PURPOSE:To prevent damage of a laser diode by detecting an error of a feedback signal and preventing an excessive current from flowing in the laser diode. CONSTITUTION:When an APC is started, data to be set to a D/A converter 7 is increased, while checking successively outputs of a comparator (COMP) 12 and a COMP 11, and when the output of the COMP 11 is inverted and becomes '1', a D/A set value at that time is saved. If the output of the COMP 12 becomes '1' before the output of the COMP 11 becomes '1', it is decided to be a fault of the COMP 11 and an error is displayed. After the output of the COMP 11 becomes '1' and the D/A set value is saved, the D/A set value is further increased, while checking the output of the COMP 12, and when the output of the COMP 12 inverted and becomes '1', the D/A set value is saved and the processing is finished. In such a way, damage of a laser diode can be prevented.

Title: Thermal transfer ink
Inventor: MOMOSE KAORU
IPC: B41J31/00
Filed: 1988-11-15
Abstract: PURPOSE:To obtain high image quality reduced in noise by preventing the reverse transfer of the ink which has already been transferred to recording paper to an ink film or a transfer mistake by incorporating a thermoplastic resin in thermal transfer inks of yellow, magenta and cyan so that the content thereof becomes more in the ink faster in transfer order. CONSTITUTION:A thermoplastic resin is contained in thermal transfer inks of yellow, magenta and cyan so that the content thereof becomes more in the ink faster in transfer order. The adhesion of an ink layer and a base layer is wet adhesion and the mutual adhesion of inks is compatible adhesion while the adhesion of the ink and recording paper is a mixture of penetrating adhesion and wet adhesion. The thermoplastic resin not only increases adhesive strength in the wet adhesion among the above mentioned adhesion systems but also raises melt viscosity and can provide flexibility to an ink film. Therefore, the adhesive strength of the ink layer of the ink film and the base layer and that of the ink layer and the recording paper are increased as the thermoplastic resin becomes more. Since the reduction in the adhesive strength due to the reduction in the amount of the resin is slight as compared with the reduction in the adhesive strength of the ink layer and the base layer, the ink layer becomes easy to transfer to the recording paper.

Title: Digital signal processor
Inventor: NAOE TOSHIYUKI
IPC: G06F17/10
Filed: 1990-10-25
Abstract: PURPOSE:To execute transfer operation with reduced error by providing a circuit for rounding processing corresponding to the tone of each circuit block to data on a data bus in the prestage of the circuit block concerned. CONSTITUTION:The rounding circuits 24, 30, 52, etc., are provided in the prestages of respective circuit blocks to which data are transferred from an arithmetic processing block 8 through a data bus 16. Even in the case of transferring data to a circuit block whose tone is shorter than that of the data bus 16, rounding processing can be executed by adjusting both the tones, so that an error can be reduced by shortening the tone. Since the rounding processing can be executed in each circuit block, a certain data can be sent to plural circuit blocks by one transfer operation in an error reduced state. Thus, transfer operation with reduced error can be executed.

Abstract: PURPOSE:To enable an operation control to be more surely further safely performed of a wireless system for an unmanned train by deciding a regular operation command in a ground station interface device processing the operation command into a continuous double data while in an ontrain station interface device processing the double data. CONSTITUTION:A command from a ground station provides a content of train number P1, running-stopping command reference point P2, runnable distance P3, connection-disconnection command P4 and emergency stop P5. A series of data 1, consisting of each command P1, P2..., and a data 2 of the same content to the data 1 are connected in series and wirelessly transmitted to an on-train station 20 from the ground station 10. Next an interface device 121 in a control unit 12 of the ground station 10 data processes an operation command to double information as before described. While an interface device 45 in a control unit 21 of the on-train station 20 resolves the double information into each data 1 and 2, when no error is provided in the data collating each data, the operation command is fed to the next operation command processor 42. When the data provides an error, the data is collated to the ground station 10 through a radio transceiver 22.

Title: Polarity exchange system
Inventor: YANG TAI-HER
IPC: G01R31/00
Filed: 1999-10-08
Abstract: PROBLEM TO BE SOLVED: To provide a polarity exchange system which keeps the stability of the circuit by deciding whether the load is connected. SOLUTION: When a power source and load are in parallel and they are of the same polarity, a straight polarity switch MSF electrically connects the power source with the load. When the current is larger than the set value, a dividing switch circuit DS is driven to shunt the current by the signal of a load current measuring device ID, and this system keeps the operation state of the circuit, and resets a series time delay circuit TD. When the power source and the load are in parallel and are of different polarity, the reversed polarity switch MSR operates after the delay time is set, and the polarity of the power source and the load is exchanged, and it becomes the same polarity of energization.  When the current is larger than the set value, the dividing switch circuit DS is driven to shunt the current by the signal of the load current measuring device ID, and this system keeps the operation state of the circuit and resets the series time delay circuit TD.
