Title: Engine operating state confirming method
Inventor: OE YOSHIFUMI
IPC: F02B77/08
Filed: 1994-05-19
Abstract: PURPOSE:To suppress source consumption of a battery by a method wherein during the stop of an engine, no answer is made even when a confirmation demand signal is received, and only during operation, a confirmation signal is transmitted to a remote control device, in a method for confirming the engine operation state of a remote control engine start system. CONSTITUTION:A remote control device 10 to start a vehicle from a remote position comprises a start switch 12 for an engine, a stop switch 14, an indicator 16 to indicate an engine state, and a control part 18. Further, the remote control device is provided with a function to transmit a signal to a unit 25 on the vehicle side when the switches 12 and 14 are pressed, a function to receive a signal from the unit 25 on the vehicle side, and a function to generate and confirm an ID code for discrimination. Meanwhile, when a confirmation demand signal for an engine state is received from the remote control device 10, a confirmation signal is transmitted only during operation of an engine and the confirmation signal is not transmitted during a stop. This method prevents the occurrence of useless power consumption.

Title: Temperature controller for hot water of bathtub
Inventor: KOYAMOTO MASANORI
IPC: F24H1/00
Filed: 1983-07-15
Abstract: PURPOSE:To ensure the effective control for temperatures of hot water of a bathtub by providing a valve to a return route of hot water from a heat exchange part to close said return route in response to the result of hot water temperature less than a fixed level of a temperature detection sensor and stopping a circulating route when the temperature of a hot water supplier is lower than a fixed level. CONSTITUTION:The amount of supplied water is detected by a level sensor 11. When the water is supplied up to its limit, a solenoid valve 12 is closed to stop automatically the supply of water. At the same time, a valve 10 is opened to circulate the hot water within a hot water supply route 7. In this case, if a hot water supplier 1 is ignited, the temperature of the hot water is increased up to a high level within a pipeline. This high temperature is detected by a temperature sensor 6. This state is kept until the sensor 6 works. In case the suppler 1 is not ignited yet, the temperature is not increased within the pipeline and therefore not detected by the sensor 6. In this case, a hot water detection sensor 8 substitutes the sensor 6 and closes the valve 10 to stop the circulation of the hot water. At the same time, a lamp, a buzzer, etc. on an operation board 13 give an alarm. Thus the factor for the defective ignition is eliminated to secure the actuation again.

Abstract: PROBLEM TO BE SOLVED: To reduce deterioration of linearity by providing a plurality of electrodes for taking out currents generated from photodiodes thereby shortening the distance to the electrode from the incident position of light. SOLUTION: Photodiodes 8a-8e are arranged in array while directing the light receiving face in one direction and electrodes 9a-9e are connected, respectively, with one end of the photodiodes 8a-8e. The electrodes are positioned between the light receiving face of the photodiodes 8a-8e and also connected with the other end of the light receiving face of the photodiodes 8a-8e. The electrodes 9a-9e connected with the opposite ends of the photodiodes 8a-8e are further wired downward on the drawing and led out to the outside. Since currents are taken out from the opposite ends of the light receiving face of the photodiodes 8a-8e, the distance to the electrode 9a-9e from the incident position of light is shortened as compared with conventional case and the effect of resistance component existing between is suppressed.

Title: Reinforcing structure of structural member
Inventor: SUZUKI TOSHIRO
IPC: E04F17/08
Filed: 1995-05-29
Abstract: PURPOSE: To prevent the generation of abrupt collapse or lateral buckling, increase plastic deformability, and make effective use of a space wherein a reinforced part is utilized as a duct or the like in a structural member which comprises an H-cross section member. CONSTITUTION: As a reinforcing material, halves of a steel pipe 55 is welded at the central part of both surfaces of a web 4 of an H-section 1 as an H- sectional beam, thereby forming an enclosed cross section area. The steel pipe 55 is mounted on an neutral axis of the H-section 1 in the longitudinal direction, and the steel pipe 55 bars almost no load under a normal load state. As a bearing fore reduces in the structural member on a compression side produced by the buckling of a compression side flange, the central axis of the entire beam is deviated to a tensile side so that the steel pipe 55 comes to share the load for the deterioration in the bearing forth as a reinforcing member, thereby preventing an abupt drop of a load resistant capacity.  The reinforcement of the enclosed cross section increases greatly the torsional rigidity of the member, and the structure is effective to resist against lateral buckling as well. It is further possible to use the internal part of the reinforced part of this enclosed cross section for wiring or an air conditioning duct.

Title: Original conveyor belt
Inventor: TAGUCHI SHIYOUJI
IPC: B65H5/00
Filed: 1984-06-25
Abstract: PURPOSE:To reduce the electrification of static electricity, making an original easily conveyable, and eliminate a conveyance miss as well as to aim at miniaturization in a conveyor belt, by using a belt provided with an outer cover layer covering the slide contact surface side with a conveying surface of a conductive core material conductor layer covering a core material with a gummous material, with white gummous matter of urethane or the like. CONSTITUTION:An original conveying belt forms a core material conductor layer 1 after coating a gummous material 7 mixed with a conductive member 6 of copper power or the like onto a core material 5, coating this conductor layer with a white gummous material 8 of urethane or the like. Therefore, a slide contact surface with a conveying surfade is white in color and friction with an original overcomes the friction between the original and the conveying surface whereby stable conveyance is attainable, and it has such a characteristic as a conductor. Therefore, a condition of conveying the original in a stable maner is secure for each friction factor between glass and the conveyor belt as well as between the original and the conveyor belt so that a conveyance miss is brought to nothing as the original is made so easily conveyable. In addition, miniaturization in a conveying device is well promoted and, what is more, static electricity is hard to be produced there owing to friction by an insulator and a conductor, therefore even if the belt rubs with the glass and the original each other, electrification is hard to occur there, thus no suction acts on the original.
