Title: Galvanic cell type oxygen concentration meter
Inventor: KUDOU HISASHI
IPC: G01N27/49
Filed: 1982-07-21
Abstract: PURPOSE:To obtain an oxygen concn. meter having along service lefe by using a metal (oxide) capable of reducing oxygen highly actively as a positive pole and lead as a negative pole of lead and using a mixture of propionic acid and alkali metallic salt or NH4 salt of an organic acid and lead compound as an electrolyte. CONSTITUTION:The positive pole 1 is a Pt plate, etc. capable of reducing oxygen highly actively, the negative pole 2 is lead, the electrolyte 3 is the mixed solution of the organic acid such as propionic acid and organic acid alkali metallic salt such as potassium propionate or NH4 salt and lead oxide. A diaphragm 4 consisting of copolymer of F2C=CF2 and H2C=CH2 is fixed to a holder 6 made of PVC resin by an O-ring 5. By measuring both end voltages of a resistance 7 between the poles 1 and 2, O2 amount transmitting through the diaphragm 4 is measured to measure O2 concn. in outer atmosphere of the diaphragm or in the solution. Thereby, H2 is not generated, precipitation of lead carbonate due to CO2 in the detecting gas is prevented, the solubility of the lead oxide is increased, and the service life is prolonged remarkably than that of conventional oxygen concn. meter using alkali electrolyte.

Title: Microwave heating device
Inventor: SUZUKI YASUMICHI
IPC: H01L21/324
Filed: 1987-05-27
Abstract: PURPOSE:To make even such a heated material as large in heat dissipation uniformly heatable at high temperature by installing a recessed projection in the central part of a surface orthogonal with an electric field in the inner surface of heating chamber or a microwave cavity resonator in the parallel direction of the electric field. CONSTITUTION:A recessed metallic projection (conductive material) 4 is fixed to a heating chamber 3 or a microwave cavity resonator with sufficient contact so as to cause an electric field to be imposed in opposition to a heat treatment surface of a substrate 1. This projection 4 exists in a surface orthogonal with the electric field, whereby it may be installed in a surface being opposed to the substrate 1 or both sides. Here, if the projection is installed with a maximum field strength point of the surface orthogonal with an inner surface of the heating chamber 3 as the center, a uniform electric field is generable in the heating chamber 3. With this constitution, even in the case where heat dissipation is large such as high temperature heating of the substrate 1, a heated material can be heated at uniform temperature.

Title: Excessive rotation preventing device for 2-cycle engine
Inventor: KOBAYASHI TAKESHI
IPC: F02D9/02
Filed: 1984-06-21
Abstract: PURPOSE:To prevent the occurrence of breakage due to excessive rotation of an engine, by a method wherein the suction negative pressure of a suction pump driven by means of a pulsation pressure in an engine crank chamber is decreased and inputted to a pressure converter, and a throttle valve is forcibly rotated in a closing direction during excessive rotation of the engine. CONSTITUTION:A pump 3 is driven by means of a pulsation pressure in an engine crank chamber, and fuel in a tank 1 is sucked through a flow-in port 4 to feed it under a pressure into a flow-in valve 5. In which case, the suction negative pressure of a suction pump 26, which is driven by means of the same pulsation pressure as that in the engine crank chamber and returns vapor in a fuel system in a diaphragm type evaporator 2 to the tank 1, is decreased and inputted to a pressure converter 34 through a resonating valve 31 which is resonated and opened thanks to vibration during excessive rotation of an engine. An actuating output during excessive rotation pushes a control lever 22 through a control lever 24, and a butterfly type throttle valve 17 is rotated in a closing direction in a condition in which a throttle valve is controlled to a full opening state. This prevents the occurrence of seizure breakage due to deficiency in lubrication occasioned by excessive rotation of the engine.

Abstract: PURPOSE:To enable to rapidly observe non-destructively a picked up image by arranging a liquid crystal on the same semiconductive substrate as a solid state image pickup element. CONSTITUTION:When a light is emitted in the state that a positive voltage VS is applied to a transparent electrode 7 and holes are stored in a p<+> type region 3, the p-n junction of the region 3 and the n<+> type region 4 is forwardly biased. Accordingly, the region 4, i.e., the electrode 20 has a positive voltage. At this time, an electric field is applied to the liquid crystal 21 formed on the electrode 21, and when it is observed through a transparent electrode 22 and a polarizing plate 24 mounted through a substrate glass 23, the part emitted with the light is observed to be bright. When a light is not emitted to a solid state image pickup element, the voltage of the region 4 is low, and since the electrode 22 is grounded, no electric field is applied to the liquid crystal 21. Accordingly, it is observed to be dark through the plate 24.

Abstract: PURPOSE:To reduce a load at the initial shift and to ensure a smooth shift of a mobile member, by shifting a fixed member of a mechanism part which damps shift of the mobile member locked at the 1st position to the 2nd position, in the reverse direction of a mobile bar. CONSTITUTION:A mechanism such as a kangaroo pocket 2 of a cassette deck that shifts a mobile member from the 1st position to the 2nd position moves from the 1st position (loading state) to the 2nd position (loading/unloading of cassette) by the functions of a locking member 8, springs 4 and 6, a piston 9 forming a damper mechanism, a cavity part 8c, etc. When the member 8 is turned at the 1st position, the part 8c moves to the piston 9. Then the pocket 2 starts moving to the 2nd position when a taper 8a' of a hollow part 8a reaches a pin 2a. Thus the piston 9 starts moving to the side opposite to the part 8c. As a result, the initial load between the part 8c and the piston 9 is reduced. Thus the initial movement is started smoothly to ensure a smooth shift of the mobile member from the 1st to 2nd position.
