Title: Absorption type water cooler and warmer
Inventor: SATO SEIJI
IPC: F25B15/00
Filed: 1990-11-19
Abstract: PURPOSE:To enable a fast taking-out of cold water to be carried out by a method wherein when a changing-over valve is changed over from its open state to its closed state, an operating signal is outputted to an absorption liquid pump for every predetermined time. CONSTITUTION:When an absorption cold water or hot water heater is changed over from a hot water supplying to a cold water supplying, a control device 28 is operated and an absorption liquid pump P is turned ON or OFF in every predetermined time until a temperature of a high temperature generator 1 reaches a predetermined temperature. That is, a pulse starting or stopping operation is carried out. Thus, it is possible to reduce a circulating amount of absorption liquid for the high temperature generator 1 after changing-over to a cold water supplying operation. As a result, an accumulation of a large amount of absorption liquid at a separator 3 can be prevented, a lack of amount of absorption liquid at a lower barrel B can also be avoided and a cavitation of the absorption liquid pump P can be prevented. With such an arrangement, when the hot water supplying operation is changed over to a cold water supplying operation, the cold water can be supplied rapidly to a load.

Title: Processing method, such as cutting, by laser
Inventor: ENOMOTO MASATOSHI
IPC: B23K26/38
Filed: 1992-11-24
Abstract: PURPOSE:To improve the threshold processing speed and threshold processing depth by irradiating a metallic workpiece with a laser beam while blowing an assist gas heated to the temp. below the m.p. of the workpiece to the workpiece. CONSTITUTION:After a heater 5 is put into an operating state, an assist gas, such as gaseous nitrogen or gaseous oxygen, is supplied. The assist gas is adjusted to the temp. (200 to 300 deg.C) below the m.p. by adjusting a slidac 16 in accordance with the temp. read by a thermocoupler 6. The aluminum plate W is irradiated with the laser beam B and is thereby cut. The viscosity of the molten aluminum metal near the aluminum plate and the surface tension thereof are degraded by the heating effect of the assist gas. Consequently, the blowing off of the molten metal by the assist gas is executed and the threshold cutting depth and threshold cutting speed are extended. As a result, the processing speed is improved and the processing surface is formed to a smooth surface.

Abstract: PROBLEM TO BE SOLVED: To provide a heat-radiating metallic member, whereby the amount of warpage in bonding a package body can be reduced, and a package for electronic component that satisfactorily radiates out wardly the heat generated during operation of the electronic comperation. SOLUTION: A copper-tungsten plate 11 has a thermal expansion coefficient, ranging from 7.5×10-6 or more to 8.5×10-6 or smaller and a copper content ranging from 7 wt.% or more to 13 wt.% or less.

Filed: 1988-12-13
Abstract: PURPOSE:To perform fast access by providing a fluid damper consisting of an annular passage whose fulcrum and axial center are set in common and fluid filled in the passage at a tracking actuator. CONSTITUTION:A boss 9 is supported rotatably on a bearing 8 mounted on a pivot 6, and an annular groove part 11 in which a pivot through hole and the axial center are set in common is formed on the upper plane of the boss 9, and silicone oil 10 is filled in the groove part 11. A control system travels magnetic heads 3a and 3b at high speed advancing from the present track position to a targeted track position on a magnetic disk 2. When the magnetic heads 3a and 3b arrive at the targeted track position, the control system desires to stop the magnetic heads 3a and 3b suddenly, however, the magnetic heads 3a and 3b desire to perform overrun by inertia. At this time, the overrun can be suppressed by the viscosity of the silicone oil 10. In such a way, it is possible to realize the fast access.
