Title: Spark erosion power source
Inventor: OBARA HARUKI
IPC: B23H1/02
Filed: 1980-02-16
Abstract: PURPOSE:To steplessly change the charged voltage of a discharge capacitor, by altering the reference voltage of a comparator. CONSTITUTION:Under an initial condition, the potential of a discharge capacitor C0 is almost zero and a capacitor C2 for auxiliary power is charged to the desired charged voltage l3 of the discharge capacitor C0. When charging operation is effected under side condition, the discharge capacitor C0 is charged from the side of a smoothing capacitor C1 until the charged voltage reaches l1. When the charged voltage of the discharge capacitor C0 exceeds l2, a transistor Q2 is turned on so that the discharge capacitor C0 is charged by the capacitor C2 for auxiliary power. Consequently, the discharge capacitor C0 is charged to a desired charged potential l3. According to this constitution, the charged voltage of the discharge capacitor C0 can be accurately and economically changed only by altering the reference voltage of a comparator CMP3.

Title: Manufacture of acicular body utilizing ion beam
Inventor: MIURA TAKESHI
IPC: C23F4/00
Filed: 1990-01-31
Abstract: PURPOSE:To easily obtain the sharply pointed acicular body and to remarkably improve the performance of various electronic detectors by irradiating the surface of an object to be machined with an ion beam till an angle formed between a normal and an incident angle of the ion beam on the surface of the object to be machined is made to the critical incident angle. CONSTITUTION:When surface 5aA of the object 5a to be machined is irradiated with the ion beam 8 at the ion beam incident angle theta formed with the normal 10, the spattering yield increases as the incident angle theta increases and becomes maximum at the critical incident angle and further, decreases suddenly when the incident angle theta increases and is diminished to zero at theta = 90 deg. (parallel incident angle). Consequently, the surface of the object to be machined is irradiated with the ion beam till the angle formed between the normal and the incident ion beam on the surface of the object to be machined is made to the critical incident angle, by which the quantity of erosion for the spattering yield is made maximum and the machining tip can be remarkably acuted with good reproducibility at a specified apex angle.

Title: Overcurrent detecting circuit
Inventor: KATAGIRI HIDEKI
IPC: G01R31/02
Filed: 1989-01-26
Abstract: PURPOSE:To suppress the adverse effect on a load circuit due to overcurrent by providing a plurality of overcurrent judging circuit, inputting the data of the current used in the load circuit, and selecting the preset value of an overcurrent detecting level for every current in use. CONSTITUTION:The judging values of overcurrent judging circuits 3 and 4 are specified as IA + DELTAiA and IB + DELTAiB (where IA + DELTAiA < IB + DELTAiB). When a current flowing through a load element 2, i.e. a current I which is consumed in a load circuit 11 is, I > IA + DELTAiA, the circuit 3 transmits the judged signal to an overcurrent judging signal line 5. When I > IB + DELTAiB, the overcurrent judging circuit 4 transmits the signal to an overcurrent judging signal line 6 by the same way. Then, an overcurrent-judging-signal switching circuit 7 switches either of the signal line 5 or 6 based on the data from a load-circuit judging signal lime 8 as to whether the current I that is consumed in the load circuit 11 is operated as IA or IB. For example, the state wherein a RAM and a ROM are switched from a standby state to an operating state is reported. A power-source cutting switch circuit 10 is switched by a control signal 9 from the circuit 7.
