Title: Wall surface travel device
Inventor: NEGISHI KOICHI
IPC: B62D57/024
Filed: 1987-11-26
Abstract: PURPOSE:To secure such a stable wall surface travel device that is compact in size, lighter in weight and less in central movement by using an elastic contractor, which is subjected to diametral expansion and deformation by feed of a pressure fluid and causes shrinkage force in the axial direction, as a driving means. CONSTITUTION:Both ends of an elastic contractor 10 are attached to supporting members 14 via a connector 12. In an interval between these supporting members 14, there is provided with a compression spring 16 surrounding the elastic contractor 10, and a suction means 18 is attached to each supporting member 14. Consequently, when a pressure fluid is made to act on the front suction means 18 and the elastic contractor 10, the rear supporting member 14 is attracted to the front. Then the rear suction means 18 is operated and the front suction means 18 is set to nonoperation, while when the pressure fluid in the elastic contractor 10 is exhausted, the front supporting member 14 is delivered in the forward direction. Accordingly, a travel device is thus moved by sequential actuation of these suction means 18 and the elastic contractor 10.

Abstract: PURPOSE:To prevent magnetic flux convergene in a field core portion by giving a taper-like form to an axially extended supporter portion for retaining the field coil of the field core so that the root of said portion will be thicker than its tip end. CONSTITUTION:The inner periphery of a field coil supporter portion 3'b of a field core 3' becomes thicker from its tip end to its root in the shape of a taper. Portions 3'a, 3'c of the field core 3' have an inner diameter equal to that of the root of the field coil supporter portion 3'b. The rotor shaft 2'a opposed to the field core 3' has a gap ga', which is uniform overall between the inner periphery of the field core 3' and said shaft. This structure is so constituted that the diameter of the shaft 2'a of the rotor core 2' will become smaller so far as tapering of the field coil supporter portion 3'b of the field core 3' reduces the inner diameter of said field core.

Title: Air conditioner
IPC: B60H1/00
Filed: 1992-11-06
Abstract: PURPOSE:To provide an air conditioner which can give a comfortable feeling to a driver by giving an adequate amount of fluctuation, and can prevent a generation of niose. CONSTITUTION:When the air is blown off at a standard blower voltage V1 at Me(medium), a fluctuation width DELTAV of the absolute value 1V is given to the V1. And when the air is blown off at a standard blower voltage V1 at Lo(low), a fluctuation width DELTAV of the absolute value 2V is given. In this case, since the fluctuation width is larger when the V1 is at Lo, a rider can feel bodily a comfortable feeling by this fluctuation. And since the fluctuation width is smaller when the V1 is at Me than when the V1 is at Lo, the rider never feels the noise owing to the fluctuation uncomfortable, and the comfortableness by the fluctuation is being maintained.

Title: Automatic light control switch
Inventor: YONEDA SAKIO
IPC: H03K17/78
Filed: 1986-12-16
Abstract: PURPOSE:To eliminate the variation of the lighting time by attaching an automatic device to a light control switch. CONSTITUTION:A current is taken from a fuse box 2 passing an ignition switch 1 and the current which has the voltage reduced by a transformer 8 flows to an exposure meter 6, and an automatic switch 5 is operated to flow it to a light control switch 9. That is, the current flowing to the fuse box 2 flows to the transformer 3 and a by-pass 4. The current flowing to the by-pass 4 passes the contact of the automatic switch 5 to operate the switch 9. Meanwhile, the current which has the voltage reduced by the transformer 3 operates the exposure meter 6. Thus, problems of forgetting to switch on a light, an individual difference of brightness, and the variation of the lighting time are resolved.

Title: Thermal accumulating type hot water heater
Inventor: INOUE TOSHIO
IPC: F24D17/00
Filed: 1989-11-17
Abstract: PURPOSE:To make a small-sized tank and provide a hot water feeding device having no discharging of water through a safety valve by a method wherein a thermal accumulating hot water heater is comprised of a water flow sensing means for hot water arranged in a hot water feeding pipe and a shielding valve to be closed by a stopping signal for a water flow sensed by the water flow sensing means. CONSTITUTION:A water feeding pipe 8 in a thermal accumulating type hot water heater is provided with a flow switch 17 for use in sensing a stopping of flow of hot water. A hot water feeding valve 10 is closed and a flow of hot water within a hot water feeding pipe 8 is stopped, resulting in that the flow switch 17 may detect it and transmit its signal to each of shut off valves 11 through a signal line 18. As a result, each of the shut off valves 16 is closed, a heat exchanger 4 and a tank 12 are shielded from a water feeding pipe 5 and a water discharging pipe 6 so as to make a closed state, so that an operating pressure of a safety valve 14a can be set higher than a vapor pressure of the heat exchanger 4. Even under a case in which the hot water feeding is stopped, a safety valve 14a is not operated with vapor pressure in the heat exchanger 4, so that the water within the tank 12 is not injected out of the device and no useless water is generated. Since no vapor is generated in the heat exchanger, it is not necessary to store water of such an amount as one to cool and condense the vapor in the tank 12 and further it is possible to make a small-sized tank 12.

Filed: 1994-11-07
Abstract: PURPOSE: To satisfactorily perform a linear or curved cutting treatment, and beautifully finish the cutting surface by using, a cutting blade having a knife-like edge part having a substantially triangular cross sectional form. CONSTITUTION: A current is applied to an ultrasonic generator 8 to supply a high frequency energy to an oscillator 3, and the energy is imparted as an ultrasonic vibration to a cutting blade 6 through a vibrating horn 4 and a connecting element 5. The cutting edge 611 of the cutting blade 6 is pushed onto a frozen fish and reciprocated to cut the fish. The cutting blade 6, which has a straight edge form having a substantially wedge-like cross section, is formed out of an edge part 61 and a back part 62. The edge part 61 has the acute angle cutting edge 611, which is formed in such a manner that the edge thickness is gradually increased toward the back part 62. A flank part is formed on the side wall of the back part 62 of the cutting blade 6. Therefore, the cutting surface of the cut frozen fish never make contact with the side wall.  Consequently, the reciprocation of the cutting blade 6 is smoothly executed, and the cutting treatment can be performed with a high sharpness.

Filed: 1999-10-20
Abstract: PROBLEM TO BE SOLVED: To heighten the opening density of a vent hole in a cowl cover without any problem in design, and also hardly observe the interior of a cowl box from the outside. SOLUTION: This cowl cover 1 is disposed in an air intake in a cowl part 20 below a wind shield B, and air ventilating parts 12, 13 formed by plural vent holes 15b, 15c are formed in a part of the cover.
