Title: Gas laser apparatus
Inventor: MURATA TAKAAKI
IPC: H01S3/097
Filed: 1989-12-08
Abstract: PURPOSE:To make it possible to keep the relationship between the duty of a pulse signal from a control signal generating means and a laser output to be linear by adjusting the duty of the pulse signal to accord substantially with the duty of the laser output. CONSTITUTION:A pulse signal of a prescribed frequency and prescribed duty is given from a control signal generating means 30 to a high-frequency power source means 27. The high-frequency power source means 27 being driven synchronously with the pulse signal, and a discharge power is given to a laser oscillating means 21 in response to the driving and a laser light is outputted therefrom. On the occasion, the laser light is outputted with a timing lagged behind the timing at which the discharge power is given from the high-frequency power source means 27 to the laser oscillating means 21. Therefore, a correcting means 32 adjusts automatically the duty of the pulse signal from the control signal generating means 30 so that it may accord substantially with the duty of the laser output. Thereby the linearity between the duty of the pulse signal from the control signal generating means 30 and that of the laser output from the laser oscillating means 21 is maintained.

Title: Pressing unit for planar semiconductor element
Inventor: ASAI ITARU
IPC: H01L23/40
Filed: 1993-12-21
Abstract: PURPOSE:To prevent the pressing force, produced by tightening a bolt constantly, from decreasing or the fluctuation in the distribution of pressing force from increasing. CONSTITUTION:Adjacent coned disc springs 51A, 52A have different diametral dimensions at the large diameter contacting parts thereof. Consequently, the protruding part of coned disc spring having smaller diameter comes into line contact with the conical face on the inside of coned disc spring having larger diameter. The contact is sustained even if pressing force is applied to deform the coned disc springs 51A, 52A. Since a small circle does not protrude from a large circle even if the relative position of the springs 51A, 52A is shifted slightly in the radial direction so long as the shift is within the difference of diameter, the springs 51A, 52A do not come into point contact but come into line contact at all times. Consequently, the pressing force produced by tightening a bolt is not consumed for abrasive deformation at the mating part.

Title: Refrigerant flow diverter
Inventor: YAMADA ARITAKA
IPC: F25B41/00
Filed: 1988-12-20
Abstract: PURPOSE:To separate a refrigerant flow on an equal basis by changing a jet current discharged from a nozzle formed in a discharge port of an inflow pipe in a direction at a right angle with a collision wall, separating said refrigerant flow into a plurality of discharge pipes in a radiation manner around the wall surface, and specifying the principal dimensions. CONSTITUTION:A refrigerant flows into a shunt device 13 from an in-flow port 14 in two phase flow, such as air phase and liquid phase, and flows out from a discharge nozzle 15. The two phase flow is subjected to reduction and acceleration by a nozzle action, and it is agitated and mixed by a collision wall 17 so that the flow may be equalized. The refrigerant is radially discharged into an in-flow port 19 of a discharge pipe 21 surrounded by a peripheral wall 18 and separated. Since neither air drain nor liquid drain is formed within a cubic volume surrounded by the collision wall 17 and the peripheral wall 18, the refrigerant maintains its mixed air and liquid phase status, the refrigerant flow is equally separated, and flows out into a refrigerant pipe 22. When the inflow pipe is specified as D1, the peripheral inner size D2 and the nozzle side L1, the distance of the collision wall from the nozzle section L2, the following results will be available: L1/D1<2.0, L1/D1<0.567, and L2<30mm.

Filed: 1989-12-13
Abstract: PURPOSE:To prevent waste of a battery even when a vehicle is running in a crowd state by detecting an average vehicle speed signal, and varying the characteristic of a battery charging voltage in response to the history of an average vehicle speed. CONSTITUTION:A power source 1 for a vehicle comprises an AD generator A, an IC regulator 2, a vehicle speed signal processor 3 and a timer 4. The regulator 2 has means 5 for selecting a regulating voltage to a normal state or an alteration. The average speed of the vehicle and its lapsed time are measured to vary the temperature characteristic of the regulating voltage of the regulator 2 or to vary the voltage of the regulator 2. If the vehicles are crowded, when the set voltage is lowered due to the rise of the surface temperature of the regulator 2, a charging voltage is raised to raise the charging of a battery. Thus, the waste and deterioration of the battery can be prevented.
