Patent JP-S58151081-A (JP)
Title: Laser power source circuit
Inventor: TOKUNAMI TAKAO
IPC: H01S5/068
Filed: 1982-03-04
Abstract: PURPOSE:To prevent faults, by restricting the supply current when the temperature of a semiconductor laser exceeds the fixed value. CONSTITUTION:A drive circuit 4 is automatically controlled 3 by comparing 301 the output of a photo detector 2 in the neighborhood of the laser element 1 with the reference voltage. By the resistor 401 and the capacitor 402 of a circuit 4, the rapid increase of the base potential of the element 403 is prevented, and accordingly the sudden current rushing into the laser element 1 is prevented. On the other hand, when the detection temperature 7 decreases to less than the set value, the output is inversed 601, and then the command to turn the laser element OFF is given resulting in protection operation 6. Next, an AND gate 501 receives this command and the external command which is interlocked with the mechanical operation, and accordingly operates switch elements 502-504 resulting in the control of the current of the drive circuit 4. By a resistor 506 and a capacitor 507, the rapid increase of the base potential of the element is prevented, and accordingly the sudden current into the laser element 1 is prevented. By this constitution, the laser current does not continue to increase with temperature, thus rush current is not generated at the time of throw-in of the power source, and therefore the breakdown of the laser element can be prevented.

Title: Heat exchanger
Inventor: HATTORI MASAJI
IPC: F28D7/02
Filed: 1985-02-21
Abstract: PURPOSE:To eliminate oxidization of internal surface of a pipe and prevent deterioration of resistance to corrosion by a method wherein two pieces or more of pipes are twisted into spiral configuration and at least one pipe thereof is expanded by flowing pressure fluid through it. CONSTITUTION:When copper pipes C, D, having the section of true circle, are flattened by passing them between rollers and are formed into spiral configuration by winding them around a drum, recessed section L2 is generated. Then, the pipe D is expanded by the internal pressure thereof generated by compressed fluid. The pipes C, D are clamped by nuts 13 through discs 11 under this condition. According to the clamping, the layer of air between the pipes C, D is eliminated entirely and a stress to push both pipes mutually at all times is generated. Accordingly, there is no possibility to generate a clearance between the pipes C, D. Refrigerant gas flows through the pipe C and hot-water flows through the pipe D, however, there is no possibility to cause a trouble such as the corrosion of water side or the like since these two pipes can be held in a good relation through such cold working only.
