IPC: G06F11/00
Filed: 1979-05-18
Abstract: PURPOSE: To perform error processing efficiently, by performing the error processing to all the devices if multiplex error is displayed with multiplex error latch and processing to the error processing only in other cases.  
     CONSTITUTION: When an error detection circuit 9 detects an error, an error address register 10 performs error processing request to program. In this case, the address of the device during processing is tentatively stored in an error latch 11, but if a new error is detected at that stage, the address is stored in the multiplex error latch. Further, if the program receives the error processing and a latch 12 does not display the multiplex error, processing is made to the latch 11, and if multiplex error is displayed with the multiplex error latch 12, error processing is made to all the devices. Thus, error processing can efficiently be made by avoiding the processing to all the devices other than multiplex error display.

Title: Electronic equipment
Inventor: HASHIMOTO YUTAKA
IPC: B65H1/00
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To make the cause of paper jamming specifiable by detecting a processing paper size, storing the number of sheets by paper size and the number of paper jamming sheets by paper size separately, and when paper processing is over, counting up respective sheet numbers as well as when there is an output request, outputting these storage data for the end. SOLUTION: When a processing means 10, processes a sheet of paper, the number of paper sheets in a first storage region of a memory means is renewed by size at a first renewal means 14, and likewise, when each sensor installed in every place detects a paper jam, the number of paper jammed sheets in a second storage region of the memory means 13 is renewed at a second renewal means 15. Thus, the memory means 13 controls the number of pressed sheets and the number of paper jammed sheets by paper size separately, and thereby a paper jamming rate by paper size is calculated in a calculating means 16. If there is an output request, there data are outputted by an output means 17, with this constitution, a fact of whether the cause of this paper jamming is at the paper side or equipment side is thus specifiable.

Abstract: PURPOSE:To obtain an anisotropic film having high DELTAn at a low cost without using a transparent substrate by filling a thermoplastic resin bag with a substance having a lower b.p. than the stretching temp. of the resin and by hermetically sealing and heating the bag, which is then cooled after stretching by the pressure of gas. CONSTITUTION:A thermoplastic resin bag is filled with a substance having a lower b.p. than the stretching temp. of the resin and the bag is hermetically sealed and heated to a temp. above the glass transition temp. of the resin. By the pressure of gas generated from the filled substance by the heating, the bag is isotropically stretched and this stretched bag is cooled while maintaining the pressurized state to form an optically anisotropic film having optically negative uniaxial property. The refractive index of the film in the intrasurface direction is higher than that in a direction perpendicular to the surface. Since a transparent substrate is not used, the film is formed at a reduced cost. The DELTAn of the film is increased by increasing the stretching rate.

Title: Data end deciding system
Inventor: INABA SUSUMU
IPC: G03B21/11
Filed: 1985-03-27
Abstract: PURPOSE:To decide a normal end or an abnormal end of data by checking the states of both a magnetic tape and a microfilm stored in a memory. CONSTITUTION:A magnetic tape reader decides the end of a magnetic tape and stops the tape feed when it detects an EOD on the tape. The presence or absence of the continuance of data read by a microfilm reader and a magnetic tape reader is recorded in a memory area designated by a program for decision of a normal end or an abnormal end of the tape. Thus an end flag is set at 'O' every time a piece of data is read, and the next reading job is carried out. The program decides the normal end of the tape when the end flags are set up with both microfilm and magnetic tape readers. While the abnormal end of the tape is decided when the end flag is set up only with a microfilm reader.

IPC: H01L23/50
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To improve the service life by forming a tip part of a diamond sintered body or a CBN sintered body, and providing a tapered inclined surface on at least one side of the tip part to keep the excellent condition of a separation surface while the wear resistance is maintained. SOLUTION: A cemented carbide tip 11 is joined with a tip of a punch base material 10 formed of cemented carbide through the silver brazing S. A root part of the cemented carbide tip 11 is formed into split comb-tooth shape, and a diamond sintered body layer 11b of approximately 500 μm in thickness is formed on the tip part of the tip base material 11a. The sintered body layer 11b is chamfered or tapered to form an inclined surface. Chamfering is achieved so that a range of 0.02-0.4 mm in length from the tip forms an angle of 30-45 deg. to the tip surface if chamfered. Tapering is achieved so that a clearance at a punch tip is 5-25% of the thickness of a work in a range where the taper depth at the tip part is 100-200% of the thickness of the work if tapered. Chipping of the tip caused by the impact during the machining is suppressed to prevent lowering of the machining accuracy.

IPC: H04L25/06
Filed: 1993-02-26
Abstract: PURPOSE:To improve the reliability of modulated signals by coding properly the received signal into the digital value in accordance with the voltage fluctuation of the received signal. CONSTITUTION:The received signal is applied to a buffer amplifier 3 from an antenna via a receiving circuit 2 consisting of a high frequency amplifier circuit, a local oscillation circuit, etc. The output of the amplifier 3 is supplied to a differentiating circuit consisting of a capacitor C and a resistor R1. The differentiating circuit extracts the rise and fall parts of the signal, and these extracted rise and fall signals are detected by the comparators 5 and 6 and then converted into the proper digital signals. Then these digital signals are converted into the digital data which are supplied to the reset and set sides of a flip-flop 7. Thus the total fluctuation of the received signals, i.e., a frequency band lower than the received signal is eliminated by the differentiating circuit despite the fluctuation of the received signal, i.e., the output of an LPF. Thus only a genuine transmitted signal is demodulated into the digital value.
