Title: Laser beam dump
Inventor: HIROSHIMA KEN
IPC: H01S3/10
Filed: 1987-12-03
Abstract: PURPOSE:To prevent the local concentration of laser beams, to obviate the elevation of the temperature of the inwall of a dump and to miniaturize a device and lengthen durability by constituting a cone for receiving light as a rotation symmetric body with a projecting section having roundness. CONSTITUTION:In a laser beam dump receiving laser beams 1 emitted from a laser oscillator and reflecting and absorbing them in the inside and emitting them to the outside as heat energy, a cone 3 for receiving them is organized as a rotation symmetric body with a projecting section having roundness. The cone 3 is formed to the rotation symmetric body with the circular projecting section having the radius of curvature R as shown in the figure. Consequently, laser beams 1 projected in the axial direction are reflected with extension from the surface of the cone 3 having a curvature, and the degree of concentration of laser beams applied to the inwall 5 of the dump is lowered, and energy density is reduced. Accordingly, the temperature rise of the inwall 5 of the dump is dropped and trouble such as burning, melting, etc., is removed, and a device is miniaturized and durability is lengthened.

Title: Boiling cooling device
Inventor: KAMEDA TAKU
IPC: H01L23/44
Filed: 1988-12-02
Abstract: PURPOSE:To obtain a compact, lightweight boiling-cooling device at a low manufacturing cost as it requires a limited quantity of refrigerants by forming an insulation sheet or layer between a stack and the base of a vessel and removing the refrigerants which remain at the lower part of the stack. CONSTITUTION:An insulating sheet 10 is disposed between a stack 3 and the base of a vessel 1. This configuration reduces refrigerants at the lower part of the stack 3 to a minimum. As the stack 3 is located at the lowest part of the vessel, its location makes the height of the vessel low. Since the insulating sheet insulates an electrically charged part completely from a grounding part, the installation of the insulating sheet makes it possible to remove the insulating space between a heating substance and the vessel; besides, it lowers the housing positions of the stack to the lowest part of the vessel and then a limited quantity of the refrigerants is required to be housed. A compact, lightweight cooling device having a low vessel is thus obtained.

Title: Electric cleaner of automatically power-controlled type
Inventor: HOSOKAWA ATSUSHI
IPC: G05D16/20
Filed: 1987-12-03
Abstract: PURPOSE: To properly and automatically control suction force or the operability of a suction port by providing a difference pressure sensor equipped with first and second pressure chambers demarcated by a slide element, the elastomer elastically energizing the slide element toward the first pressure chamber and a slide resistor wherein a movable contact element slides on a fixed resistance film element in connection with the slide element. CONSTITUTION: When a filter 37 is clogged, the pressure loss in the filter 37 becomes large and air quantity lowers and suction force lowers. At this time, since the static negative pressure at the intermediate point between the filter 37 and an electromotor 38 lowers largely, difference pressure becomes large and the slide element 17 of a clogging sensor 1 is lowered toward the second pressure chamber 19 against a coil spring 20 and output resistance R1 becomes small. As a result, the charging time of a condenser 60 becomes short and the input power of an electromotive blower 38 is increased and suction force increases to correct the lowering of suction capacity caused by clogging. When the filter 37 is not clogged, the output resistor R1 of the clogging sensor 1 is held to high resistance and the input power of the electromotive blower 38 is held to a standard state.
