Title: Brazing process of heat radiating blade
Inventor: TASHIRO MINORU
IPC: H01L23/367
Filed: 1982-11-15
Abstract: PURPOSE:To adjust any brazed gap due to dimensional error automatically by a method wherein a part of radiating part are thinly machined. CONSTITUTION:An oxygen-free copper plate is cut into rectangular shape to form a radiating blade 12 simultaneously by means of thinning both ends in the direction of width thereof. Firstly the thinned parts are mutually bent into arc shape in the reverse direction. Secondly the part 12 is radially arranged around an anode through a brazing plate 13 using a jig. Thirdly a Kovar alloy wire with less coefficient of thermal expansion is bound around the parts 12 through a band-like metallic sheet to be assembled depressing the blade 12 on the anode 11. Any uneven gaps between the blade 12 and the outside of the anode 11 due to any dimensional error may be offset by bending deformation of the thinned parts.

Title: Optical displacement meter
Inventor: TERAMAE KATSUHIRO
IPC: H03K17/28
Filed: 1992-07-28
Abstract: PURPOSE:To stably operate the delay timer of the title displacement meter without depending on the rise characteristic of an external power supply. CONSTITUTION:When a reset terminal R is set to an L level, a reset operation is released and a monostable multivibrator for a light-emitting delay timer 24 becomes active. At this time, since a trigger terminal T is grounded by a capacitor C and it is set to the L level, the monostable multivibrator (the light-emitting delay timer 24) is operated stably. When a power supply is turned on, the rise of the power supply is detected in a halfway part of the rise of the power supply, and the rise time of the power supply depends on the performance of an internal power supply. However, the reset terminal R is controlled by a power-supply rise detection circuit in the light-emitting delay timer 24, and the trigger terminal T is fixed by a resistance R5 and the capacitor C2. As a result, the rise timing of the title displacement meter functions stably and correctly.

Title: Semiconductor laser module
Inventor: ISHIKAWA SHIGETA
IPC: H01S3/13
Filed: 1990-07-31
Abstract: PURPOSE:To relieve the position fixing accuracy necessary for a semiconductor laser or optical fiber by using a high-aberration lens formed into the shape of a rotating body obtd. by shifting the central axis of the symmetrical curves of a projecting shape from the axis of rotation at one end for coupling the semiconductor laser and the optical fiber. CONSTITUTION:An exit beam of an ID pellet 1 is coupled to the optical fiber 2 by the high-aberration lens 4. This high-aberration lens 4 is formed of the shape of the rotating body obtd. by shifting the central axis of the symmetrical curves of the projecting shape on both face sides of the lens. The focuses are not at one point but are circular with this high-aberration lens 4 and, therefore, the intensity distribution of the light power density in the part where the light beams are focused is uniform over the flat wide range of the peak. The misregistration characteristic in the direction perpendicular to the optical axis of the ID pellet 1 or the optical fiber 2 in the coupling loss of the ID pellet 1 and the optical fiber 2 is the characteristic of the wide flat region. The position fixing accuracy of the semiconductor laser and the lens is relieved in this way.

Filed: 1983-10-27
Abstract: PURPOSE:To easily obtain an optional temperature coefficient and an optional output voltage by setting the 1st resistance and the 2nd resistance and adjusting the 3rd resistance, and obtaining a reference voltage from the 3rd resistance. CONSTITUTION:An operating current is flowed to a resistance R23 by transistors (TR) Q25 and Q26 constituting a current mirror circuit to cause a voltage drop V1. The base-emitter voltage of a Q21, on the other hand, is converted into a current by a Q23 and a resistance 22, and the current mirror circuit consisting of TRs Q27-Q28 flows a current to the resistance R23 to cause a voltage drop V2 with this curre. A reference voltage Vref=V1+V2 is developed across the resistance R23. This voltage has a positive and a negative temperature coefficient, so the resistance ratio is adjusted to obtain the reference voltage having a zero temperature coefficient or an optional temperature coefficient easily. The zero temperature coefficient is set only by the ratio of the resistances R21 and R22 and the resistance R23 is adjusted to obtain an optional reference voltage.
