Title: Hydraulic spacer
Inventor: SHIMOII TSUTOMU
IPC: B23D19/06
Filed: 1988-06-15
Abstract: PURPOSE:To eliminate the slide of a holder and permit cost cut and obtain the miniaturized constitution by forming a hydraulic chamber for each holder and fixing the holder onto a shaft through the expansion and contraction of the holder. CONSTITUTION:When a cutter 5 is fixed onto a shaft, the cutter 5 is fixed onto a holder 1, and the holder 1 is warmed to increase the inside diameter and then fitted onto a shaft 6. When the holder 1 returns to the normal temperature through the lapse of time, the inside diameter reduces, and the shaft 6 and the holder 1 are tightly fitted and fixed. When the cutting width of a coil varies, and the cutter 5 is shifted in the shaft 6, a hydraulic pressure is supplied into a hydraulic chamber 2 from a valve 4, and the inside diameter of the holder 1 is increased by the pressure, and tight fitting is generated between the shaft 6 and the inner surface 8 of the holder 1, and the fixed holder 1 can move freely in the shaft 6. Further, after the holder 1 is shifted to a desired position, the hydraulic pressure is discharged from the valve 4, then the inside diameter of the holder 1 is contracted, and the holder 1 is fixed onto the shaft 6.

Title: Hemming device of sewing machine
Inventor: IKEDA HISASHI
IPC: D05B69/00
Filed: 1995-06-14
Abstract: PURPOSE: To eliminate the need for mechanical and electrical adjustments of step-detecting sensitivity by differentiating a detection signal which a step detection means outputs, so as to extract the trailing or leading edge of the detection signal, and detecting any step from the waveform of the trailing or leading edge. CONSTITUTION: When a step detection signal (voltage signal) A is output from a step sensor 22, a differentiating circuit 40 extracts its trailing or leading edge and converts it into a differential signal B for output to an integrating circuit 42. The integrating circuit 42 removes extra signals such as vibrations caused by noises at the flat part of the differential signal and converts the signal into an integral signal C. An amplifier 44 performs amplification to form a signal D. A comparator 46 compares the signal D with a reference voltage Vset, maintains it only for the duration of the voltage in excess of a reference voltage Vset, and converts it into a pulse signal E for output. Any step is detected by means of the pulse signal E.

Filed: 1993-06-18
Abstract: PURPOSE:To obtain a highly accurate wafer of little surface undulation and thickness irregularity by suppressing the temp. rise of an abrasive grain slurry by controlling the temp. in the close vicinity of the surface of the roller of a wire saw for cutting an ingot. CONSTITUTION:An abrasive grain slurry 12 controlled in its temp. is allowed to directly flow to a roller 2 and the temp. control of the slurry 12 is performed directly under the roller 2 by a temp. sensor 5. When the temp. rise of the abrasive grain slurry 12 caused by the generation of heat in an ingot 3 and a wire saw 1 is detected by the sensor 5, the abrasive grain slurry 12 cooled by a heat exchanger 10 is immediately supplied from a slurry tank 6 by a slurry supply pump 8 and rapid temp. control can be performed without generating a time lag. In the case of ON/OFF control, when a cooled slurry supply valve 15 is turned ON/OFF little by little, the temp. control directly under the roller 2 is extremely reduced in temp. change rate as compared with the temp. control in the slurry tank 6 and the deflection of the roller is stabilized and cutting accuracy is enhanced.

Title: Ic memory card
Inventor: SHIRATO SHUICHI
IPC: G11C5/00
Filed: 1990-06-06
Abstract: PURPOSE:To eliminate the troublesome operation of a change over switch at the time of exchanging a main battery by using a solar battery as an auxiliary battery for backing up a volatile memory at the time of exchanging the main battery. CONSTITUTION:The solar battery 9 is used as the auxiliary battery for backing up the volatile memory 3 at the time of exchanging the main battery 8. At the time of exchanging the main battery 8, an IC memory card is extracted from an external terminal equipment. But, an environment such as an office to which illumination is given is considered as a place where the secondary battery 8 is exchanged, and the volatile memory 3 comes to a backed up state by the super power of the solar battery 9 at that time. Thus, the troublesome operation of the change over switch at the time of exchanging the main battery becomes unnecessary, and held data is prevented from being extinguished at the time of exchanging the others.

Filed: 1977-12-12
Abstract: PURPOSE: A sludge feeder which can prevent the fluctuation of the quantity of supplied substance and supply constant quantity of it by providing a pressure application means to the supplied substance in a hopper.  
     CONSTITUTION: In a sludge feeder with a hopper 1 and suitable number of screws 2 arranged at its bottom for transferring supplied substance, a pressure application means, for example, a vertical pressure applying screw 3 is provided at some position in said hopper 1 preferably near the side wall on the outlet 4's side of the supplied substance.

Abstract: PURPOSE:To reduce current consumption by providing a serial/parallel conversion means applying serial/parallel conversion to an input signal string, a comparison means comparing a parallel output and an N-bit frame synchronizing code pattern for each bit and a count means or the like. CONSTITUTION:A signal string inputted from a signal input terminal 1 to a shift register 3 is subjected to serial parallel conversion, a parallel signal is outputted from the register 3 and inputted to EX-NOR circuits (4-1)-(4-N). Then the signal is compared with a preset frame synchronizing code pattern for each bit and the result is given to a shift register 7, where the data is outputted by each bit at a speed more than the N times the transmission speed of the input signal string. The output is given to a counter 9, number of coincidence signals in the N-bit output is counted and fed to a discrimination circuit 6 via a selector 18. The circuit 6 outputs an E level discrimination signal when the content of the counter 9 is discriminated to be a prescribed value or over, and a frame synchronizing code detection signal is outputted via DFF 23, 24 and an AND gate 24. Thus, the power consumption is reduced.
