Title: Semiconductor laser driving circuit
Inventor: MATSUDA NOBUHIDE
IPC: H01S5/068
Filed: 1987-02-02
Abstract: PURPOSE:To prevent a semiconductor laser from suffering damage due to an excess current by a method wherein a rectifying device is connected with the semiconductor laser in parallel and the same polarity. CONSTITUTION:A semiconductor laser driving circuit is composed of a semiconductor laser 1, a photodetector 2, a constant current circuit, and a rectifying device 4. The rectifying device 4 consists of plural bodies connected in series and has the same polarity as the semiconductor laser 1. Namely, a voltage, which increases a current rapidly, depends on number of the bodies connected in series. Therefore, by controlling the voltage, most of the current flows through the semiconductor laser when it is equal to or smaller than the rated current of the semiconductor laser and flows through the rectifying device 4 when it is larger than the rated current. Thereby, the semiconductor is prevented from an excess current.

Filed: 1983-02-15
Abstract: PURPOSE:To enable predetermination of the temperature for preliminary heating of samples over Curie point by switching off the heater during irradiation with electron beam so as to make the magnetic flux generated from the heater zero. CONSTITUTION:The present device is provided with an X-axis deflecting coil 15 for scanning samples, a Y-axis deflecting coil 16 for moving scanning position and an electric heater 31 for preliminary heating of the samples prior to heat treatment with electron beam.

Title: Squareness measuring instrument
Inventor: YAMAGUCHI SHINICHI
IPC: G01B3/56
Filed: 1988-02-05
Abstract: PURPOSE:To speedily take a measurement with a concrete numeral by providing a dial gauge which contacts the surface that a contact support body provided to a main body contacts. CONSTITUTION:When this squareness measuring instrument is used, the dial gauge 5 is adjusted to zero, namely, a square reference adjustment is made. An article 23 is mounted on a surface plate 22, the lower part of a measurement surface 23a is brought into contact with the contact support body 3, and the upper part is made to abut on the contactor 10 of the gauge 5. The contactor 10 is pressed slightly backward against the surface 23a to move back a measurement spindle 7 slightly, but the spindle 7 still projects forward from the zero position. Consequently, the display part 8 of the gauge 5 displays the quantity (mm) of the projection displacement of the spindle 7 from the zero position 0 as a symbol (e.g. +) indicating its direction. This display value represents the forward inclination of the surface 23A to a perpendicular surface, i.e. squareness in concrete. Consequently, the squareness is measured speedily.
