Abstract: PURPOSE:To attain miniaturization and low cost of a power supply system and further a communication equipment by providing a switch interrupting a main signal processing circuit from the secondary side power supply system at power failure, using the switch so as to interrupt the power supply thereby decreasing the capacitance of a capacitor of the secondary power supply system. CONSTITUTION:The secondary power system is divided into a transmission/ reception circuit 7 including the transmission/reception function and the multiplex function of power failure information and a main signal processing circuit 8 multiplexing and demultiplexing the main signal other than the circuit 7. Then the transmission/reception circuit 7 is always connected to the secondary power supply system, and the main signal processing circuit 8 is connected to the secondary power system via a switch 9. The switch 9 is switched by using a circuit 4 for detecting the primary side power supply voltage drop to interrupt the main signal processing circuit 8 from the secondary side power supply system. Thus, the capacity of the capacitor 6 is reduced remarkably, the size of the power supply circuit is reduced and then the miniaturization of the communication equipment is realized.

IPC: G01R27/26
Filed: 1992-10-23
Abstract: PURPOSE:To measure the degradation of insulation by measuring the induction loss of insulator of measured cables and comparing with that of a normal cable. CONSTITUTION:Both total degradation and partial degradation are detected by measuring the induction loss of insulator. For example, measurement voltage Vo is impressed from an oscillator 10 to the inductor 20 of a measured cable and voltage Vx appearing in a detection resistor (r) is measured with a lock-in amplifier 17. At this moment, a switch SW is at OFF. Then, the switch SW is at ON and the phase of Vo is shifted for -90 deg. with a phase changer 12. Vx' attenuated with an attenuator 16 is added with an adder 15 to the voltage Vx appearing in the detection resistor (r). The gain of Vx' is controlled with the attenuator 16 so that the lock-in amplifier 17 value becomes minimum. After controlling the gain, loss component voltage VXR of the Vx appearing in the lock-in amplifier 17 can be measured.

IPC: C23C14/06
Filed: 1994-12-14
Abstract: PURPOSE: To impart superior wear resistance by forming a hard coating film of a compd. of Al and Ti as metallic elements and C and N as nonmetallic elements having a specified compsn. on the surface of a substrate and coating the surface of the hard coating film with boron nitride. CONSTITUTION: A hard coating film consisting of two layers is formed on the surface of a substrate. The 1st layer is formed on the substrate side and has a chemical compsn. represented by the formula (Alx Ti1-x )(Cy N1-y ) (where 0.56<=x<=0.75 and 0<=y<=0.4). Boron nitride is laminated as the 2nd layer on the surface of the 1st layer. The thicknesses of hard coating films as the 1st and 2nd layers are preferably regulated to 0.1-20μm each. Since the BN coating film having a low coefft. of friction has superior affinity for and reactivity with the (Al, Ti) (C, N) coating film and does not deteriorate the adhesion of the (Al, Ti) (C, N) coating film to the substrate, the problem of peeling at each interface is not caused, hardness and oxidation resistance as the entire hard coating film are enhanced and wear resistance is improved.
