Title: Trimming knife device for cutting pyramid type sample buried block
Inventor: SAKAI TOSHIO
IPC: B26D1/02
Filed: 1978-08-04
Abstract: PURPOSE: To make it possible to accurately and easily cut a pyramid projection at the leading end of a smaple buried block by attaching a trimming knife to a pair of knife holding portions which are arranged at a desired angle of inclination.  
     CONSTITUTION: Trimming knives 2 and 3 are attached to a pair of knife holding portions 1a and 1b which are formed at a knife holding member 1 at a desired angle of inclination α and α'. The holding member 1 thus constructed is mounted on the knife holder 5 of a microtome M. On the other hand, a sample burying block 4 is mounted in a sample holder 6. After the position adjustment, if the coil 7a of a drive coil 7 is energized, a permanent magnet 7b repulses to turn a lever 8. As a result, the both side portions at the leading end of the block 4 are cut and removed. Then, if similar operations are performed after the holder 6 is turned 90 degrees, there is formed at the leading end portion of the block 4 a pyramid 4a which has a desired side of inclination.

Title: Parity circuit check system
Inventor: KIHARA ATSUSHI
IPC: H03M13/00
Filed: 1987-04-20
Abstract: PURPOSE:To attain the judgement of a fault or the like of a parity circuit by switching the parity system from the odd number (even number) parity used at present into the opposite even number (odd number) parity at parity check and using a parity circuit so as to detect a parity error. CONSTITUTION:At first, the parity system is subjected to switching process from the odd number parity into the even number parity in the step ST 1. Then a data is read from a memory in the step ST 2 and the parity error is detected by the parity circuit. Since the parity circuit detects a parity error when the memory data is normal because the parity system is switched. In detecting an error, the interruption processing is applied and an interruption production flag is set in the step ST 3. Then the interruption production flag is decided in the ST 4 and when the flag is set, it is judged to be in normal operation and when not set, it is judged as an error of the parity circuit.

IPC: H03K17/04
Filed: 1980-07-15
Abstract: PURPOSE:To increase the dV/dt rating between the collector and the emitter and to reduce the switching loss, by giving a reverse bias between the base and emiter, when a main transistor (TR) in an inverter using TRs is nonconductive. CONSTITUTION:When pulse transformers 18, 28 are not driven, no current flows to diodes 30, 40, 31, 41, a TR59 is nonconductive, the base current of a TR58 flows to turn on the TR58, and the base and emitter of a main TR2 is back-biased. When he pulse transformers 18, 28 are driven, a current flows to the diodee 30, 40, 31, 41, and a base current flows to the TR59, resulting in turning on the TR59 and turning off the TR58. Thus, a TR2 is forward-biased to be conductive. In this case, if a pulse transformer is not driven, the TR58 is conductive and the base and emitter of the TR2 is back-baised, then it is quickly nonconductive. The current from the collector to the base due to the capacitance between the collector and the emitter capaictance between the collector and the emitter capacitance caused by the increase in a voltage between the collector and emitter flows to the TR58, allowing to reduce the current flowing to the TR2.

Title: Photosemiconductor switch circuit
Inventor: SAGAWA AKIO
IPC: H01L31/12
Filed: 1978-08-09
Abstract: PURPOSE: To hold ignition sensitivity and dv/dt capacity compatible each other where resistance between gate and cathode of photo SCR is not given high at giving light ignition signals.  
     CONSTITUTION: A luminous element 3 is ignited and SCR1 is radiated to ignition from applying a negative pulse signal to the input of logical element for ignition of photo SCR 1. In this case a luminous element 6 is not luminous due to a presence of inverter 7, and a phototransistor 5 is kept off. There works only a resistance RGK consequently between gate and cathode of SCR1, and hence it operates at high light ignition sensitivity from keeping the resistance RGK high. When input signal C does not work, the element 3 is not luminous but the element 6 gets luminous. The phototransistor 5 is therefore turned on, SCR1 is shortcircuited between cathode and gate, and thus dv/dt capacity is extremely improved. The dv/dt capacity can therefore be ketp high without deteriorating ignition sensitivity.
