Patent JP-H02149729-A (JP)
Title: Exhauster for two-cycle internal combustion engine
Inventor: TAKASHIMA KAZUTOSHI
IPC: F02B75/02
Filed: 1988-11-30
Abstract: PURPOSE:To avoid the malfunction of an exhaust valve and the shrinkage of an exhaust passage area when reducing exhaust noise by installing the exhaust valve through the adoption of a construction to have a catalyzer for the valve body of the exhaust valve. CONSTITUTION:Exhaust gas is throttled through a vent hole of a valve body 20 by setting an exhaust valve 19 at a fully closed or nearly fully closed position when idling or trawling. When cruising at a low or medium speed, exhaust gas is throttled by squeezing an exhaust passage 18 through the closure of the exhaust valve 19 or its setting at an appropriate opening. Since the construction is so made that the exhaust valve 19 then exposed to the exhaust gas of a high temperature comes into contact with a catalyzer 25 for exhaust gas, the catalyzer reacts with the exhaust gas, and the unburnt portion of fuel and lubricating oil as contained in the exhaust gas is burnt out with the catalyzer 25 whose temperature keeps on rising. Therefore, the valve body 21 of the exhaust valve 19 is free from any adhesion of fine carbon particle so that the malfunction of the exhaust valve 19 and the shrinkage of the exhaust passage area can be avoided.

Title: Needle disposal machine
Inventor: KUDO HARUO
IPC: A61G12/00
Filed: 1992-10-14
Abstract: PURPOSE:To treat used needles on the spot so as to safely perform subsequent handling by providing an inductance within an electric path so that as the end of a needle is fused by Joule heat an arc discharge occurs between the end of the needle and a main electrode. CONSTITUTION:A used needle 1 is inserted into a hole 5 from a hole and the end of the needle is pressed against a main electrode 11 and the root of the needle is brought into contact with an auxiliary electrode 7 and then a chuck (electrode) 9 grips and holds the root of the needle 1 in place. Thereby a current flows through the needle 1 via the chuck electrode 9. The area of contact between the end of the needle 1 and the main electrode 11 is so small that the end of the needle is melted by Joule heat generated, and that a gap soon forms and shuts off an electric path. Then an inductance generates a back electromotive force and an arc discharge occurs between the end of the needle and the main electrode 11; therefore, the end of the needle is further melted and the gap is soon enlarged and the discharge stops while the needle 1 is made spherical at its end and sterilized by heat.

Title: Method for thermoforming plastic sheet and mold therefor
Inventor: YAMAMOTO HIDEKI
IPC: B29C51/32
Filed: 1987-11-30
Abstract: PURPOSE:To form an aggregate having vessel-like recessed parts, which can be separable from one another, by a method wherein a mold, on which specified air outlets are provided, is employed. CONSTITUTION:A thermoforming mold 1, on which a large number of vessel-like recessed parts and continuous perforation-like air outlets 3 bored on boundary lines between respective vessel-like recessed parts are provided, is used. A molding sheet, which is heated upto a somewhat higher temperature, is seated onto the mold 1 so as to come into close contact with the air outlets 3 and finally is vacuum-formed or air-pressure-formed. Since the air outlets 3 are provided continuously, the holes made on the formed sheet turn into continuous perforation, resulting in allowing to separate the formed sheet along the perforation as the parting boundary. The formed sheet can be used in the form separated for every one recessed part. Further, the usefulness is attained by employing as an inside partition sheet for housing cakes or machine parts in a casing.

IPC: D06F34/22
Filed: 1989-11-20
Abstract: PURPOSE:To heighten a washing effect and to control a washing time, etc., in corresponding to dirt such as mud-dirt, by a method wherein the title device is composed so that both a saturation time and the water permeability at its time are detected by the output signal change of a permeability detector during washing-operation, and washing is controlled in corresponding to the product between the saturation time and the permeability. CONSTITUTION:The light-emitting output of a permeability detector 19 is controlled at a fixed value. The data of an optical sensor 8 is periodically inputted and after agitation is started, it is decided whether water permeability is higher than the criterion level for a liquid detergent. If the permeability is lower, it is decided that its washing agent is a powdered detergent, and it is made a control flag for the following washing and rinsing processes, and is stored. After that, the output signal change of the detector 19 is detected, and if a voltage change is made small, it is decided that water is saturated, and a saturation time and the water permeability at its time are stored and they are made a washing-control data. After that, an additional washing time is found from a control table. This varies in corresponding to the product between the permeability and the saturation time. The longer the additional time is, the lower the permeability is and the longer the saturation time is.

Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To improve contrast at a high temperature to maintain high contrast in a broad temperature range by inverting a data signal according to ambient temperature. SOLUTION: In the case of application of an ON waveform, a transmittance gradually falls so that a display darkens as an impressed voltage Vop increases, while the transmittance increases so that the display lightens when the impressed voltage Vop further increases. In the case of application of an OFF waveform, a light state in which the transmittance is high is maintained at first, and finally, the transmittance falls so that the display darkens, as the impressed voltage Vop increases. In an area (b) wherein sufficient contrast is obtained, the ON waveform causes a black display, while the OFF waveform causes a white display. In an area (c) wherein the impressed voltage Vop increases further than in the area (b), sufficient contrast is also obtained though the ON waveform and the OFF waveform respectively invert.  This driving method utilizes the area (c) in which the ON waveform and the OFF waveform invert.
