Title: Enameled bathtub
Inventor: NAKATANI MASANOBU
IPC: C03C14/00
Filed: 1980-07-22
Abstract: PURPOSE: To well prevent the cracking of an enamel layer when enamel is baked and to provide a high quality enameled bathtub having a metallic tone by adding inorg. particles coated with a metal to the enamel layer.  
     CONSTITUTION: Enamel mixed with mica particles or inorg. particles of feldspar, quartz or the like coated with titanium oxide, Al, Cr or other metal is baked to manufacture the desired enameled bathtub. The inorg. particles are prepared, e.g., by spraying mica particles from a nozzle and spraying molten titanium oxide on the sprayed particles from other nozzle or vacuum-depositing titanium oxide. Ground coat enamel 2 contg. cobalt oxide, etc. is baked on the base material 1 of a bathtub made of iron or the like to form an intermediate enamel layer 3. Enamel frit mixed with said inorg. particles is then sprayed at the baking temp. of the layer 3, i.e., at about 1,000°C and baked to form an enamel layer 4.

Title: Cooling structure for electronic equipment
Inventor: HASEGAWA KATSUHIKO
IPC: H05K7/20
Filed: 1990-04-17
Abstract: PURPOSE:To improve a cooling capacity dramatically by installing a flow outlet which permits the air which has cooled the interior of a housing to flow outside, to the lower part of said housing and providing a ventilation door which opens the flow outlet based on the action of electronic equipment so that it may be opened and closed. CONSTITUTION:The heat generated in a printed wiring board or the like during the operation of electronic equipment is cooled with the air which flows in from a flow inlet 5. This air is discharged outside from a plurality of flow outlets 9 which are opened to an exhaust port 6 or a ventilation door 10. The plurality of flow outlets 9 are bored on the bottom of a housing so that they may permit the air 4, which has cooled the printed wiring board 2 or the like, to flow out like the exhaust port 6. At the same time, the ventilation door is pivotally mounted, which opens this flow outlet 9 based on the action of the electronic equipment in such a manner that it may be opened or closed. This construction makes it possible to improve the cooling capacity dramatically and hence eliminate the need for a cooling fan 8.

Title: Optical fiber cable having reinforcing layer
Inventor: TANAKA CHIHAYA
IPC: G02B6/38
Filed: 1982-06-11
Abstract: PURPOSE:To realize an optical fiber cable which can stand high tension and lateral pressure, is not affected by external force, and not damaged, by forming at least the outer peripheral part of a high strength fiber group around the optical fiber in one body so that the outside part can support the tension of the cable. CONSTITUTION:An optical fiber 1 is completely covered with a solidified layer of a high strength fiber group 3 with a buffer layer which has an air gap or is rich in air gaps or a buffer layer 2 in between. The buffer layer 2 is an aggregate of a high strength fiber group and rich in air gaps, whereas the solidified layer 3 is formed of a high strength fiber group impregnated into and filled with an appropriate adhesives or filler in the layer 3 and adhesives or filler is solidified to some degree and the fibers are glued to each other. Since the optical fiber cable of this invention has the high strength fiber groups around the optical fiber 1 and at least the outer peripheral part of the high strength fiber groups is formed in one body with the filler, the outer peripheral part uniformly protects the cable and supports the tension of the cable. Therefore, this optical fiber cable can stand lateral pressure and high tension and is not affected by external force and not damaged.

IPC: F04C29/12
Filed: 1992-04-21
Abstract: PURPOSE: To simplify the structure so as to make the manufacture easier and reduce the noise during operation to the lowest possible extent by mounting a valve spring on a valve reed. CONSTITUTION: A valve reed 30 is air-tightly contacted with a valve seat 20 to close an outlet 22 during the intake stroke of a compressor. At that time, a gas coolant flows into a cylinder bore through an inlet 24. Then, when the pressure of the compressed gas coolant is greater than the pressure of a discharge chamber and the pressing force of a valve spring 31 during the discharge stroke of the compressor, a circular portion 33 of the valve reed 30 is retreated from the top of the valve seat 23 by the discharge pressure of the compressed gas coolant to open the outlet 22. When the compressor proceeds from the compression stroke to the intake stroke, the circular portion 33 bent upward of the valve reed 30 is returned to the position on the valve seat 23 by the pressing force of a bent section of the valve spring 31.

Title: Powder particle collecting device
Inventor: WATANABE TOSHIO
IPC: G03G21/00
Filed: 1983-06-09
Abstract: PURPOSE:To obtain a safe and inexpensive dust collecting roll having high dust collecting efficiency and requiring no high voltage power source by providing an electret layer on the surface of a rotary body having a desired shape. CONSTITUTION:A sheet material having an appropriate thickness and suitable property as electret is applied to cover a peripheral surface of a conductive roll 3. The surface of the covered layer of the roll 3 is irradiated with corona radiation or electron beam radiation while maintaining the temp. at ca.150-200 deg.C, to transform the surface to a permanently charged body having positive or negative polarity. When such dust collecting roll 1 is used in a brush cleaning device, high voltage DC source or voltage cord is rendered unnecessary because the dust collecting roll 1 itself is a permanently charged body; accordingly, the cost and space are saved. Moreover, the electret layer 2 may be suitably formed to a cylindrical, columnar, beltlike or any othershape of the rotary body in accordance with the field of use of the rotary body.

IPC: H01L29/812
Filed: 1991-05-08
Abstract: PURPOSE:To prevent storage of electrons in an InAs channel layer due to presence of deep doner in an A>=Sb barrier layer and to facilitate a pinch-off operation. CONSTITUTION:Acceptor impurity of a concentration exceeding deep doner is added to an AlSb barrier layer 4 at the time of growing a laminated structure by an MBE method. After a surface protective SiNx film 6 having hydrogen permeability is deposited, atomlike hydrogen 7 is diffused to inactivate excess acceptor for the deep doner. As a result, storage of the electrons in an InAs channel layer 3 is suppressed, the layer 4 becomes a high resistance, and a normal OFF type element can be realized.

Filed: 1984-05-23
Abstract: PURPOSE:To obtain a video camera which has a good color saturation even in a low illuminance by reducing the level of a burst signal with a variable control means when the open state of a stop of a lens is detected by an aperture value detector. CONSTITUTION:An optical lens aperture value detector 15 monitors the stop of an optical lens 1, and the detection signal is sent to a burst signal varying device 14 when the stop is set to the open state. Though the burst signal varying device 14 sends normally the burst signal from a synchronizing signal generator 13 to a burst signal superposer 11 in the through state, the device 14 reduce, the level of the burst signal by a prescribed quantity when the detection signal from the optical lens aperture value detector 15 is sent. Consequently, the level of the burst signal in an NTSC composite video signal 17 is reduced at this time, and the color saturation is improved only when the stop of the optical lens 1 is opened (that is, only when the video camera is operated in a low illuminance).

Title: Feeding of fuel
Inventor: NOGI TOSHIJI
IPC: F02M61/18
Filed: 1988-04-27
Abstract: PURPOSE:To form the uniform mixed gas by feeding fuel relatively much into the part opposite to the cylinder wall surface of an intake valve. CONSTITUTION:The direction of a fuel injection valve 1 is deflected in the direction close to the center axis of a cylinder 8, for the axis line connecting the center of an intake valve and the fuel injection valve 1. Therefore, the fuel which jets out from the side close to the cylinder wall surface of an intake valve 2 reduces, and the adhesion quantity of fuel on the cylinder wall surface can be reduced. The deflection angle is set so that the outermost side of the jetted fuel mists coincides with the center axis of the stem of the intake valve 2, and the deflection angle is ordinarily set to 2-10 deg.. Therefore, the uniform mixed gas can be formed in the cylinder 8.
