Title: Improved array and method of activating modulated solid-state laser array having reduced thermal crosstalk
IPC: H01S5/026
Filed: 1993-02-18
Abstract: PURPOSE: To reduce or eliminate thermal crosstalks that induces modulation between individually addressable lasers as a monolithic multi-laser array. CONSTITUTION: Lasers 52 and 54 are formed which include two active regions (amplification regions 56 and 58 and modulation regions 60 and 70) which are optically coupled with each other. Modulation of a laser output is carried out by varying an internal optical loss of a modulation region and is known an Q switching. The loss control is carried out by (1) varying a reverse bias voltage to be applied to the modulation region, by (2) selectively connecting p and n-type regions in the modulation region together or cutting off each other, by (3) selectively connecting or disconnecting the modulation region to or from the ground potential, or by (4) increasing a current of the amplification region to enable laser light emission and simultaneously to cancel thermal effects caused by the increase in emitted optical power.  The Q-switching operation of the laser causes the laser in operation to be cooled.

Title: Manufacture of ceramic coil component
Inventor: BANDAI HARUFUMI
IPC: H01F17/00
Filed: 1990-02-08
Abstract: PURPOSE:To manufacture a small and high-impedance ceramic coil in a simple process by a method wherein a ceramic green sheet on which a line-shaped conductive film is formed is wound, the conductive film is arranged spirally, the film is baked and a cylindrical ceramic sintered body is formed. CONSTITUTION:A spiral conductive part used to generate an inductance portion is formed in a line shape on a ceramic green sheet; the conductive part is formed by a simple process. The ceramic green sheet is wound and baked collectively; a cylindrical ceramic sintered body is formed. When an electric current is applied through external electrodes 26, 27, a magnetic flux is generated in the lengthwise direction of the cylindrical ceramic sintered body 22. Since the direction in which the magnetic flux is extended and the thickness direction of the conductive part 25 are mutually perpendicular, the magnetic flux is not disturbed so much by the conductive part 25. Consequently, the effective cross- sectional area of a coil is expanded effectively. Thereby, it is possible to obtain a ceramic coil which is small-sized but whose inductance value is high.

Abstract: PURPOSE:To spare cooling driving energy by opening or closing a valve of a supply hole formed in a transmission chamber when driving an engine cooling fan in correspondence to the fluid shifting temperature to reduce noise introduced when the fluid moves in the transmission chamber from a storage chamber. CONSTITUTION:When a temperature sensitive operating body S senses a set temperature at the low temperature side upon driving a cooling fan of an engine, a pin body 16 shifts outwardly. An outside stopper (t) separates from a valve arm 13b nearer to a cover 5, and a valve 13 opens an outside fluid supply hole 4a' of the transmission chamber 8 against the spring force, thus a torque is transmitted in an inside transmission chamber 7'. Further, when the temperature rises up and the operating body S senses the set temperature on the high temperature side, the inside stopper (t)' loses a distance (d), and opens in outside supply hole 4b' against the spring force acting on the valve arm 14b nearer to the partition wall. The torque is transmitted within an outside transmission chamber 8'.
