Title: Electric field detector
IPC: H01L21/66
Filed: 1992-03-23
Abstract: PURPOSE:To measure an electric field of a soft material by a method wherein a contact part is formed into a triangular pyramid shape to increase the contact area between a measured electrode and the contact part. CONSTITUTION:The tip of a triangular-pyramid-shaped contact part 10 is brought into contact with a measured electrode 11. Therefore, the potential of the measured electrode 11 is directly introduced into a probe. A measured electric field 12 is created between the contact part 10 and the electrode 7 of an electro-optical crystal 8. Therefore, the phase difference of a light pulse which is transmitted through the inside of the electro-optical crystal 8 is further changed in accordance with the field intensity and, as a result, a polarization plane is changed. The light pulse is reflected on a light reflecting plane 9 provided on the other surface of the electro-optical crystal 8 and introduced into an optical fiber 3 through wavelength plates 6, a polarizer 5 and a lens 4. The light is detected by a photodetector. The intensity of the light introduced into the optical fiber 3 is proportional to the field intensity. By utilizing this fact, the field intensity of the measured electrode 11 can be measured.

Title: Power source circuit and power supplying method
Inventor: OGAWA KOICHI
IPC: G06F1/32
Filed: 1995-03-24
Abstract: PURPOSE: To suppress useless consumption of battery power in the process of manufacturing VTRs by setting the microcomputer at the service interruption mode when products are in process. CONSTITUTION: When a VTR 10 is under condition of a product in process, the power of battery source 3 is supplied to a power source terminal C2 of a system control microcomputer 5 and an initializing circuit 6. Here, because the output current from the battery source 3 passes a diode D2 and a diode D3, the voltage drop is small and the voltage value of the power source terminal C2, namely, the voltage value of the initializing IC 7 exceeds the value preset at the IC 7. Accordingly the initializing IC 7 switches the initializing signal from the low level to the high level. Because of this, the system control microcomputer 5 detects the voltage value of a voltage detecting terminal C1 after initializing itself.  When products are in process, the line power source 2 is not turned on, and the service interruption detecting signal is at 0V, and thereby the system control microcomputer 5 sets the operation mode at the service interruption mode.
