Title: Deterioration diagnostic apparatus for insulation coating of coated wire
Inventor: ITOU KEIKO
IPC: G01N27/02
Filed: 1995-02-06
Abstract: PURPOSE: To diagnose dielectric deterioration, and the precursory state thereof, due to pinhole, crack or void by measuring the degree of deterioration of the insulation coating of a coated wire nondestructively and quantitatively. CONSTITUTION: A personal computer 1 comprises a CPU 2, a ROM 3, a RAM 4, and an FDD 5. A measuring probe 11 comprising a sponge-like electrode 13 containing a conductive gel encased in a tubular electrode case 12 is set to cover the insulation coating 16 of a coated wire 14. A voltage signal in a predetermined frequency region is applied through a preamplifier 9 between the electrode case 12 and the wire conductor 15 of the coated wire 14 and then the current value and phase are measured. The degree of deterioration can be determined based on the impedance Z and the pattern of frequency characteristics of capacitive component Cx and tanδ. With such arrangement, dielectric deterioration can be diagnosed easily and nondestructively.

Title: Protecting device for variable speed motor
Inventor: KINOSHITA HISASHI
IPC: H02P29/00
Filed: 1982-02-05
Abstract: PURPOSE:To prevent the runaway of a motor by interrupting a power source with a comparator which produces an output when the motor speed is higher than the prescribed value, differentiating the signal of a tachometer generator and a comparator which produces an output when the value is lower than the prescribed value. CONSTITUTION:A speed setter 1 is compared with the feedback signal of a tachometer generator 6, thereby controlling the speed of the motor 5. At this time the signal of an amplifier 3 is inputted to a comparator 8 to generate a high level output when the speed difference of the motor 5 is higher than the prescribed level, the signal from the generator 6 is differentiated by a differentiator 9, the absolute value is discriminated by a comparator 10, a high level output is generated when it is lower than the prescribed value, the both outputs are applied to an AND gate via a discriminator 11, thereby interrupting the power source. Accordingly, when the speed feedback signal is not fed back due to malfunction, the power source is rapidly interrupted, thereby stopping the runaway of the motor 5 to effectively protect the motor.

Title: Drive control circuit for motor for film winding of camera
Inventor: NAKASHIMA YUKIO
IPC: G03B17/42
Filed: 1980-02-16
Abstract: PURPOSE:To miniaturize a control circuit and to improve its control precision by constituting the control circuit so that when the run of a take-up film stops, the power supply to the motor will be excluded by inverting the output of a counting circuit. CONSTITUTION:Counting circuit 6 inverts the output when counting pulses more than clock pulse signals (c) counted in maximum interval t1 of a reset pulse signal. Therefore, when a film is running for prescribed winding, differential pulse signal (d) resets counting circuit 6 to hold its output signal (f) at level H, switching element 2 stays on, and motor 1 continues to rotate. When the film is wound by one frame and shutter switch 3 is released, potential (a) is held at L, switching element 2 turns off, and motor 1 stops, thereby completing the winding of the film. Thus, the control precision is improved and the circuit is miniaturized.
