Title: Automatic preset system electronic channel selector
Inventor: TAKESHITA MASARU
IPC: H04N5/44
Filed: 1980-12-29
Abstract: PURPOSE:To achieve accurate channel selection, by providing a synchronizing separation circuit picking up a horizontal synchronizing signal of a TV broadcast signal independently with a CRT deflection circuit, and stopping the sweep of the tuning voltage through the detection of the coincidence between the picked-up horizontal synchronizing signal and deflection pulses. CONSTITUTION:A synchronizing separation circuit 1 is exclusively provided with an electronic channel selector, and only horizontal synchronizing signals are separated and picked up from a TV broadcast signal. The coincidence between the phases of the picked-up horizontal synchronizing signal and the deflection pulse formed at a horizontal scanning deflection circuit 2 of a TV receiver main body side is detected at a coincidence detection circuit 3. The detected signal is smoothed at a capacitor C1 and applied to an electronic tuner 4 to stop the sweep of a tuning voltage. With such constitution, no coincidence detection signal is outputted from the circuit 3 due to noise, allowing sure channel selection.

Title: Reciprocating type electric shaver
Inventor: MUKAI KIYOTAKA
IPC: B26B19/28
Filed: 1988-07-28
Abstract: PURPOSE:To make it possible to smoothly reciprocate an oscillator by providing resilient drive pieces each having a lower end fixed to an oscillation transmitting member and an upper end secured to the rear surface of the oscillator. CONSTITUTION:Rotation of a cam shaft 6 of an eccentric cam 4 is transmitted to an oscillation transmitting member 5. Drive pieces 7a, 7b are held perpendicularly to an oscillator 8. The cam shaft 6 moves from either of end positions. As the cam shaft 6 approaches the center of the reciprocating stroke, the drive pieces 7a, 7b deform so that their lower ends approach the cam shaft 6 so that they take an inclined condition. Further, in consideration with the motion of the cam shaft 6 with a microscopic scale, the drive pieces 7a, 7b twist around the oscillation transmitting member 5 in a certain condition. However, such a deformation is absorbed up by the resiliency of the drive pieces 7a, 7b. Accordingly, the oscillator 8 does not deflect substantially, thereby it is possible to repeat a fixed reciprocating motion.

Filed: 1986-08-12
Abstract: PURPOSE:To improve the reliability and to gain low stress effect while securing the sealability and surface appearance by a method wherein a semiconductor element is sealed by epoxy resin compound containing specified kind of polysiloxane rubber. CONSTITUTION:Assuming alkyl group or alyl group as R, polysiloxane rubber is produced by making mixed-reaction of polysiloxane (silicon oil) A with functional group mainly comprising repeating unit represented by the formula I while added or added condense-reacted to each other as well as added or added condense-reacted to epoxy group with polysiloxane B mainly comprising the same unit reacted to each other as well as a hardener. A semiconductor element is sealed by means of epoxy resin compound mixed with the rubber, epoxy resin and the hardener.

Title: Catalyst combustion device
Inventor: KAWASAKI YOSHITAKA
IPC: F23D14/18
Filed: 1989-07-21
Abstract: PURPOSE:To enable maintenance of stable heating and heat application efficiency for a long time by a method wherein a catalyst active component non-carrier layer is formed in the vicinity of the surface on the upstream side of a catalyst layer positioned facing a heat ray transmitting substance, and a heat resisting porous sub stance carrying a catalyst active component is disposed in the vicinity of the surface on the downstream side of the catalyst layer. CONSTITUTION:A part A in the vicinity of the surface on the upstream side of a catalyst layer 7 positioned facing a heat ray transmitting substance 8 is a layer not carrying a catalyst activate component, and a part B on the downstream side carries the active component. Thus, under a state in which catalyst combustion is started, combustion reaction is effected at the part B on the downstream side, the part A is heated through transmission or radiation of a reaction heat, and heat is dissipated to an external part in front through the heat ray transmitting substance 8. Reaction at the carrier part B is effected in a position in the vicinity of the non-carrier part A at an initial stage. But, with the progress of a long term use, activation of the part thereof is gradually reduced, and a reaction center position is moved to the downstream side. Since heat is effectively imparted on the non-carrier part A to feed a radiation heat, no influence is exercised to a major degree on a quantity of heat imparted through the heat ray substance 8 and a visual temperature.

Abstract: PURPOSE:To contrive rise of breakdown voltage between emitter collectors and reduction of collector saturation voltage at a trideffusion-type transistor by forming high dense second base region in low dense first base region so as to cover an emitter region. CONSTITUTION:An N type buried layer 2 is formed on a surface of a P type substrate 1. Secondly, P<+> type buried layers 3a, 3b are formed. Next, after an N type epitaxial layer 4 is subjected to grow, P<+> type first collector region 5 is formed from the surface of the layer 4. Subsequently, P type second region 6a and P<+> type dielectric division region 6b, which become a part of collector region, deffusing impurity from the surface of the layer 4, are formed. An N type first base region 7 is formed in the region 5, thereafter an N<+> type second base region 8 is formed in the region 7. In this case, the region 8 is trimmed to cover at least whole area of a P<+> type emitter region and to be higher density than a region 7, also to be shallow junction. Finally, P<+> type emitter region 9a is formed. According to this manufacturing method, the breakdown voltage between the emitter base short collectors is risen.

Abstract: PURPOSE:To stabilize the effluent hot water temperature by providing a first reference flow rate and a second reference flow rate to put a shut-off solenoid valve into open or close state, and setting the second reference flow rate lower than the first one. CONSTITUTION:When the flow rate detected by a flow rate sensor 4 is higher than a first reference flow rate, a water solenoid valve 6 is opened to supply water into a water supply pipe 2, and the influent water is divided and supplied to water pipes 10 and 20. Then, as a flow switch 22 is closed and control circuits 50 and 60 are put into action, a combustion apparatus 40 start burning to heat up the influent water through heat exchangers 11 and 21, and the water from the heat exchangers joins into a hot water supply pipe 2a and flows out. When the water flow rate detected is less than the first reference flow rate and higher than the second reference flow rate that is lower than the first one, the water solenoid valve 6 is not closed. Therefore, as the combustion apparatuses 30 and 40 are operated in a steady state, the temperature of effluent hot water from the hot water supply pipe 2a can be stabilized.
