Title: Manufacture of electrochromic element
Inventor: UEHARA YUUJI
IPC: G02F1/1523
Filed: 1982-12-24
Abstract: PURPOSE:To form easily an electrochromic (EC) film superior in characteristics in a short time by forming an oxidation color-developing type EC film by the ion plating method and subjecting to hydration treatment. CONSTITUTION:(i) A metal, such as Ir, of an evaporation source 3 in a crucible 2 is evaporated by radiation of electron beams from an electron gun 4 in a bell jar 1 maintained in a high vacuum state, ionized with a high frequency coil 5, and the produced Ir ions are accelerated in an electric field (a signal 10 shows a high voltage power source) between a substrate 6 and the crucible 2 to plate the substrate 6. At that time, a very small amt. of oxygen is introduced through an inlet 7 to react Ir with O2 and an IrO2 film is formed on the substrate 6. (ii) Then, this film is immersed, e.g., in an H2SO4 soln., and a square wave voltage is impressed repeatedly over 10-odd times and subjected to hydration treatment. Thus, an oxidation color-developing type EC film is obtained by said electrolytic treatment.

Title: Power device

IPC: H02M3/155
Filed: 1992-09-02
Abstract: PURPOSE:To reduce short-circuit currents by feed-back controlling a chopper circuit when excess short-circuit currents are detected at a time when load is short-circuited. CONSTITUTION:Currents flowing through load 15 are detected as the potential on the load 15 side at a time when currents flow through a load-current detecting resistor 23. The load 15 side potential is compared with reference potential by a comparator 25 and a difference section is obtained, and the difference section is compared with a preset value by a control circuit 19 and overcurrents are detected. When overcurrents are detected, a switching element 17 is on-off controlled at a duty ratio narrowing on-duty so as to dissipate the overcurrents. Consequently, even when overcurrents are detected by the load 15 side, the switching element 17 of a chopper circuit 14 is feedback- controlled. Accordingly, short-circuit currents can be reduced at a time when the load 15 side is short-circuited.

Title: Digital signal reproducing device
Inventor: HIKAWA KAZUO
IPC: G11B5/09
Filed: 1986-10-02
Abstract: PURPOSE:To omit unnecessary data modulation, identification (ID), parity operation or the like by operating a counter only for a block whose synchronization is detected at the time of a fast search reproduction in a digital tape recorder or the like using a rotary head. CONSTITUTION:When the contents of a symbol counter 26 is cleared by a synchronizing signal detected from a reproduced signal through a synchronizing signal protective circuit 24, a symbol counter counts up one block length and the contents of a RAM in which demodulated data are written are read out by using the count value as an address. The output of an AND circuit 28 is turned to an 'L' signal by a carry signal obtained through the counter 26 and a decoder 27 and an 'L' rapid search mode signal obtained from a terminal 31. The 'L' signal and the output of the circuit 24 are processed by a NOR circuit 25 and outputted as a clear signal. Since the counter is not cleared by a carry signal or the like and is kept at the stopped state until the succeeding synchronizing signal is detected, unnecessary data modulation, ID, parity check operation or the like due to dropout or the like is not executed.

Title: Information processor
Inventor: YAMADA YASUTAKA
IPC: G06F9/38
Filed: 1988-09-21
Abstract: PURPOSE:To enable monitoring the working state of each subject logic and to monitor the logic working states on occasion by dividing a pipeline process at each executing stage. CONSTITUTION:When an instruction process is started, the working states of the necessary logic circuits A0-A5 set in a processor 1 are sent to a monitor 2. A control circuit drives the conditional selection circuits 5 and 6 and the update permission circuits b0-b5 with a command of a service processor 3. The counters A00-A50 and D00-D07 count the measurement events and their generating times and overheads. When both processors 1 and 3 instruct the discontinuation of the working of the monitor 2, a control circuit 4 stops each counting job. Thus a pipeline process is divided for each executing stage. As a result, the logic working necessary for the process jobs is limited and the working of each subject logic can be monitored. Thus it is possible to clearly monitor the logic working states of each subject logic on occasion with application of a high-degree pipeline process system even though the multiple pipelines are processed in the same time band.
