Filed: 1985-10-09
Abstract: PURPOSE:To set the power consumption at the time of holding by night and also to exert no influence on the efficiency of a device by combining a means for detecting a voltage of a solar battery and a latch type switch. CONSTITUTION:A DC voltage detecting circuit 1 monitors a DC voltage of a solar battery 2, and when it exceeds a prescribed value, a control power source active command PSON is outputted. By this command, a switch ON for turning on a latch type switch MC1 is closed, therefore, a main contact point is closed and also a contact point (b) is opened. As a result, a control power supply source 3 becomes active, and also the detecting circuit 1 is detached from a DC bus. On the other hand, when the voltage of the battery 2 becomes below a prescribed value at night, the main contact point is opened, and the contact point (b) is closed by closing a switch OFF for turning off a latch type switch MC1. As a result, the control power source 3 is disconnected, and also the detecting circuit 1 is turned on to the DC bus. Accordingly, at the time of holding by night, the power consumption becomes zero. Also, since the latch type switch is used, an adverse influence is not exerted on the efficiency of a device.

CONSTITUTION:When bating hot water B from jetting nozzles 5, 5, through a circulation passage 7, the jetting amount and the jetting pressure of the bath hot water are arbitrarily changed by controlling a drive motor M by a controller C-2 and an inverter IN. Also, when jetting the water B in the body A of the bath through a jetting channel 9, the water level of the bathing water B is detected at a water level detection sensor S, the drive of a circulation pump P is controlled by the inverter IN, and the bathing water is slowly discharged. Next, when executing the discharge by inverter control, a high speed discharge is executed until t-1, the discharge is eased off until t-2, and after that the discharge operation is slowed down as much as possible. Also, in order to raise the function of a cleaner, the number of revolutions is dropped at t-3, raised again at t-4, and after alternately repeating this, a gradual discharge is executed at t-5. Thus, the bathing hot water is discharged smoothly.

Abstract: PURPOSE:To elongate the life of a cathode filament and prevent pollution of a metal film by constructing the cathode filament in annular shape and disposing it around an opening of a housing and further providing an annular cover as to the cathode filament and maintaining this cover at an equal or lower potential relative to the cathode filament. CONSTITUTION:An annular cathode filament 33 is disposed around an opening 22 from which ions are led out, i.e., at a position where the led out ions are avoided. Further, this cathode filament 33 is received in an annular receiving space 32 formed by a cathode cover 34 for the ions. Therefore, the cathode filament 33 is not subjected to sputtering by the led out ions so that the wearing of the filament 33 can be prevented and its life is elongated. Further, as a result of that the wearing of the filament 33 is prevented, the pollution of the interior of a vacuum chamber, in which an ion source is provided, is also prevented. In addition, the cover 34 is maintained at an equal or lower potential relative to the filament 33. Thus, a sufficient amount of thermions can be supplied to the space near the ion source.

Title: Cooling structure
Inventor: KIMURA NAOKI
IPC: H01L23/36
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To obtain a cooling structure whose cooling performance is excellent and which maintains an excellent characteristic in a long-term use, by a method wherein ends on one side of a plurality of fin elements are fixed to the face on one side of a heat transfer block, and a support block is fixed to ends on the other side of the plurality of fin elements. SOLUTION: A component 10 to be cooled is fixed to a heat transfer block 12 via a low thermal expansion member 11. A plurality of fin elements 130 are attached to the heat transfer block 12 so as to be erected side by side. A fin 13 is constituted as an aggregate of the plurality of fin elements 130. A support block 15 is fixed to the upper side of the fin elements 130. In addition, parts between the fin elements 130 are restrained mutually by support members 14. Then, since the coefficient of thermal expansion of the heat transfer block 12 is considerably larger than that of the low thermal expansion member 11, a laminated body which is composed of the low thermal expansion member 11 and of the heat transfer block 12 is going to warp so as to be convex, but it is possible to restrain its behavior. As a result, it is possible to reduce an influence on the component 10, to be cooled, due to the generation of a warpage.

Abstract: PURPOSE: To provide the subject compound, by feeding water to a distillation column reactor containing a bed of an acidic ion exchange resin, at a point above the height of the bed and feeding simultaneously an isoolefin-containing hydrocarbon to the column at a point below the bed, bringing the both into contact with the above resin and separating the subject compound from the column at a point below the bed by fractional distillation.  
     CONSTITUTION: Tertiary alcohols (e.g. t-butanol, t-amyl alcohol) are produced by feeding water 12 to a catalyst bed 2 of an acidic ion exchange resin at a point just above the bed and an olefin material 5 (e.g. isobutylene- or isoamylene-containing material) at a point below the bed, and effecting the reaction in the catalyst bed 2 at 140-185°C under 25-225 psig. The reaction mixture is boiled in the catalyst bed, followed by withdrawing alcohol solution with higher boiling point from line 10 through a point 4 below the bed. The unreacted hydrocarbon is withdrawn from the column at a point above the bed and a portion of the unreacted hydrocarbon is refluxed. The amount of water in the alcohol fraction in the lower part of the distillation column is measured and the water feed rate is adjusted to maintain the amount above 0, but below the azeotropic concentration, so that the catalyst is maintained in the hydrated condition.

IPC: B23F19/10
Filed: 1988-09-12
Abstract: PURPOSE:To prevent machine accuracy or machining accuracy from lowering due to chips caught between sliding surfaces or the like of the machine by tilting the top surface of the lowermost moving table which supports a cutter spindle thereby causing the chips produced with the cutter to slide down quickly in one direction. CONSTITUTION:The top surfaces of moving tables 11, 12 supporting a cutter spindle are tilted. Therefore, chips produced by cutting and falling down on the moving tables 11, 12 slide down along the tilted surfaces and are removed. While the spindle of the cutter for chamfering gears is normal to the work axis 5, the cutter spindle can also be made parallel to the work axis. Therefore, by changing the angle of the cutter axis relative to the work axis 5 and the cutter, other kinds of machinings such as key groove cutting, tapping, drilling, etc., can also be performed.
