Title: Apparatus for keeping low-temperature secondary pump at low temperature
Inventor: IKEDA AKIRA
IPC: F04B53/08
Filed: 1982-03-05
Abstract: PURPOSE:To enable to cool a pump automatically, by providing a temperature controlling orifice in both of a minimum-flow pipe and a gas releasing pipe, and producing a small amount of fluid flow through the two orifices by the discharge pressure of the pump. CONSTITUTION:A temperature controlling orifice 16 is provided in a minimum- flow pipe 12 in parallel with a valve 11, and another temperature controlling orifice 17 is provided in a gas releasing pipe 14 in parallel with a valve 13. Since the discharge pressure of a low-temperature primary pump 3 is acted when operation of a low-temperature secondary pump 5 is stopped, a low-temperature liquid in a suction pot 6 is carried little by little to a low-temperature tank 1 via the orifice 16 and the pipe 12, so that a pump body and a motor are cooled. At the same time, the low-temperature liquid in the suction pot 6 is also supplied little by little to the low-temperature tank 1 via the orifice 17 and the pipe 14, so that the inside of the pot 6 is cooled. Thus, it is enabled to keep the pump 5 at a low temperature automatically.

IPC: G11B7/125
Filed: 1987-02-18
Abstract: PURPOSE:To make troubles, such as jitter, uneven pitches, etc., avoidable, by constituting a semiconductor laser and/or collimator lens so as to move in order to avoid the variation of the relative positional relation between a light emitting point and the collimator lens caused by the positional movement of the light emitting point. CONSTITUTION:When the light emitting position of a semiconductor laser 10 moves in the lateral direction due to mode hopping, the movement is immediately detected by a light emitting position detecting device 32 and light emitting point position moving information is inputted to a moving device 42 from the detecting device 32. Then the moving device 42 moves the semiconductor laser 10 and/or a collimator lens 24 in the direction, in which the movement of the light emitting point can be cancelled, in accordance with the input. Therefore, even if mode hopping takes place, deflection of a laser beam 16 after passing through the collimator lens 24 does not occur and troubles, such as jitter, uneven pitches, etc., can be avoided.
