Title: Power focus device
Inventor: MATSUSHIMA HIROSHI
IPC: G02B7/09
Filed: 1989-12-07
Abstract: PURPOSE:To obtain the power focus device which has excellent operability by forcibly stopping a lens from moving when focusing is detected halfway in manual focusing. CONSTITUTION:A PGC is a pulse generating circuit which outputs a pulse by the rotation of a focus link 1 associatively with the focus link 1. An LMCC is a lens driving control circuit which sends a driving signal for a lens driving circuit LMCC when the pulse generating circuit PGC generates the pulse and turns off the lens driving circuit LMCC when a focusing decision circuit FCC decides focusing. If the focusing is decided during the manual focusing, the lens is stopped forcibly to facilitate the lens stopping position at the focusing position and the lens begins to be driven when manual focusing operation is performed by a specific quantity after the lens is stopped. Consequently, the shift from the focusing position to another position by the manual focusing is carried out with extremely good operability.

IPC: H01R4/02
Filed: 1987-12-17
Abstract: PURPOSE:To improve mounting efficiency by bending leads at the side of a component body. CONSTITUTION:A component body 1 and leads 2 bent inside the body 1 are provided. For example, a chip component is formed in a structure in which the leads 2 are disposed at the lower side of the body 1.

Abstract: PURPOSE:To make it possible to the density of intrinsic point defect by a method wherein an external magnetic field is impressed on a crystal sample, an ultrasonic wave is passed through the sample while it is cooled, and a change in the acoustic velocity of the ultrasonic wave in the crystal sample or the relation between a change in absorption of the ultrasonic wave and a temperature of cooling the crystal sample is measured. CONSTITUTION:Cooling equipment having a sample measuring box 4 is so designed that it is inserted between superconducting magnets and that a magnetic field of 0 to 10 tesla, at least, can be impressed with continuous variation. Measurement of the relative acoustic velocity of an ultrasonic wave transmitted through a crystal sample 2 from a first piezo element ultrasonic transducer 31a to a second piezo element ultrasonic transducer 32a is executed by comparing a pulse signal generated by an ultrasonic pulse generating device 31 with the pulse signal detected by an ultrasonic wave detecting device 32. Based on the result of measurement of the acoustic velocity and the amount of fall of a V-T curve showing the relation between the acoustic velocity of the ultrasonic wave in the crystal and temperature, the density of intrinsic point defect is determined by proportional conversion.
