Abstract: PURPOSE:To prevent the generation of strains by forming integrally a metal base and a part of a metal frame that consist of W-Ni-Cu in a specific composition respectively. CONSTITUTION:W powder whose average grain size is 1.5mum is mixed with W powder whose average grain size is 9mum in a weight ratio of 70:30 while Ni powder whose average grain size is 5mum is blended with Cu powder whose average size is 2mum in 90 weight percentage, 7 weight percentage and 3 weight percentage respectively so that their total weight may be 200kg. Paraffin wax whose melting point is 80 deg. is mixed with polyethylene whose decomposition and burning out temperature is 550 deg.C so that their volume ratio may be 3:1, thereby producing an organic binder. This organic binder is mixed with W, Ni and Cu mixed powder so that their total weight may be 100kg in a volume ratio of 30:70.

IPC: G11B27/34
Filed: 1981-08-28
Abstract: PURPOSE:To perform detection with less errors at a low and high speed running, by the operation of frequency-division for a slit passing signal generated from a reel, through the use of a switching means, a frequency dividing means, a frequency dividing means, a frequency-division operation and control means and a frequency-division operation means. CONSTITUTION:Slits provided to a hub are counted with a rotary detector 1 of photoelectric or magnetic system to obtain the number of revolutions of a supply side 11 and a winding side 12. Both the number of revolutions are applied to count means 31 and 32 through frequency-dividing 21, 22 and any of the count means 31, 32 is selected at a selective operation means. A switching means 6 transmits a signal to a display means 5 at a low speed mode only. In the high speed mode, an output of a frequency-division operation means 8 is frequency- divided 9 for display through the control of a switching means 10. The means 8 applies 1/4-frequency-division for a larger output signal out of those of the detectors 11 and 12, and a value of smaller output is summed as it is through the control of a frequency-division operation and control means 7. The control means 7 is operated with the amount of tape running indicated by the display 5. Thus, the amount of tape running for each mode can accurately be detected.

Abstract: PURPOSE: To reduce the time needed for the continuity test of wiring by setting a start and end addresses in a source pin and test pin counters which address a master net data and tester net data so that undesired regions are not scanned.  
     CONSTITUTION: Through the start address register 38 and the end address register 39, the start address and end address are set in the source pin counter 33 and the test pin counter 35 in a wiring continuity testing apparatus 3. Through the counters 33 and 35, a pin matrix unit 34 is scanned, and the good or bad of the continuity is decided in a detection circuit 37 by comparing the test data with the master net data at the corresponding address. The result is sent to a data transmission/reception unit 31 according to the address corresponding to the pin transferred from the counter 35 to a test pin register 36. Because the scanning region can be limited as desired, the need for scan and test on undesired regions is eliminated. Therefore the continuity testing time can be reduced.

Title: Source voltage detecting circuit
Inventor: IKEBE HISAKI
IPC: H03K19/003
Filed: 1991-06-06
Abstract: PURPOSE:To prevent logic circuits of a microcomputer and a controller which are used at low voltages from running away. CONSTITUTION:The output of a source voltage transformation part 1 which transforms and outputs a source voltage is received and when the output voltage exceeds a certain value, a CMOS inverter 2 holds the output at a low level. A reset signal output part 3 outputs a voltage required to reset the logic circuits of the microcomputer in a trailing stage, but when the input from the CMOS inverter 2 goes down to the low level, the output is held at the low level. Then the microcomputer, controller, etc., are never reset even at any voltage by using a resistance or depletion type N channel field effect transistor instead of an enhancement type n channel field effect transistor of the part which transforms and outputs the source voltage.
