Title: Water heater
Inventor: ANDO ATSUSHI
IPC: F24H1/10
Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To prevent water being neglected in a state where it leaks out by starting a timer when control of opening a motor driven valve is started, and closing the motor driven valve until a water flow detector outputs a water flow interruption signal when a motor driven valve monitor sensor does not output a valve closing detection signal. SOLUTION: A driving motor M that is rotated only in one direction is controlled to open a motor driven valve 20 until an output of a cam switch 13 is changed from an on signal to an off signal in order to start hot water supply operation when an output of a water flow detector outputs a water flow interruption signal. The operation control is executed after the motor driven valve 20 is opened. Simultaneously with the valve opening control, a timer is started, and when the output of the cam switch 13 does not output a valve closing detection signal until the elapse of predetermined time is confirmed, the control of closing the motor driven valve 20 is repeated several times. If the cam switch 13 does not output the valve closing detection signal, then the driving motor M is operated until the water flow detector outputs the water flow interruption signal.

Title: Electrodeposition painting method
Inventor: HIBINO IKUKAZU
IPC: C25D13/22
Filed: 1986-12-10
Abstract: PURPOSE:To form electrodeposition coated films having an optimum film thickness for every material to be coated for which the required thickness of the coated film is different, by disposing plural stages of bus bars in the conveying direction of the materials to be coated and changing the number of the stages of the bus bars to be energized according to the kinds of the materials to be coated. CONSTITUTION:The materials to be coated, 4a, 4b are hung to hangers 3 and are conveyed along guide grails 2a by a transport conveyor 2 so that the materials are dipped in the paint 1a in an electrodeposition tank 1. The position where the materials 4a, 4b are fully marged is detected by a limit switch LS1. Electricity is fed from a 1st current rectifier 8 through the bus bars 7 and power feed terminals 6 to execute electrodeposition painting of the materials 4a, 4b in the conveyance section B1. Electrodeposition painting is similarly executed in the conveyance section B2 as well by the power feed from the 2nd current rectifier 12. The differences in the required energization time by the kinds of the materials 4a, 4b are adjusted by properly interrupting the power feed to the bus bars 16, 18, 20 at the time of the transfer to the conveyance sections B3, B4 and B5. The energization time is thus controlled by the kinds of the materials 4a, 4b and the film thicknesses thereof are thereby changed.

Title: Interpolated scanning radar equipment
Inventor: URUSHIDO TAKASHI
IPC: G01S7/02
Filed: 1993-10-28
Abstract: PURPOSE:To level the unevenness of covering range in all bearings and to acquire stably a target in the vicinity of a maximum detecting distance, in a radar equipment of an electronic scanning type. CONSTITUTION:The direction of an electromagnetic wave beam is deflected slightly at every (n)th (n=1, 2, 3,...) scanning and thereby the unevenness of a covering range pattern is leveled equivalently. In order to bring about this function, a beam control signal from a beam controller 9 is corrected by an about 1/2 interval at every (n)th scanning by a beam interpolating circuit 8. Since each of phase shifters 2-1 to 2-m is driven on the basis of the data thus obtained, the electromagnetic wave beam synthesized in a space is shifted by the about 1/2 beam interval at (n)th scanning. Thereby, the covering range pattern is leveled and even a target in the vicinity of a maximum detecting distance can be detected stably.

Title: Toll collection system for toll road
Inventor: UCHIDA KEN
IPC: G07B15/00
Filed: 1996-11-05
Abstract: PROBLEM TO BE SOLVED: To lighten the burden on a toll collector by eliminating the need for a vehicle to stop temporarily at a toll gate and to prevent congestion of vehicles by making the vehicles smoothly pass through the toll gate. SOLUTION: A driver who uses a toll gate of a toll road registers his or her license number in a toll gate computer 5 in advance and adopts a prepaying or postpaying method for a toll. When a vehicle 7 enters the toll gate, a vehicle detecting device 10 detects the entry of the vehicle 7 and a license number recognition device 11 recognizes the license number from the license plate 8 of the vehicle 7 and sends it to a booth receiving machine 3. The booth receiving machine 3 inquires the license number of a toll gate computer 5 and turns ON a registration confirmation pilot lamp 12 when the number is already registered to allow the vehicle 7 to pass. The vehicle 7 after entering the toll gate confirms the illumination state of the registration confirmation pilot lamp 12 while slowing down and then starts when the registration confirmation pilot lamp 12 illuminates. Further, when the passing vehicle is unregistered, the same toll collection as before is performed.

Abstract: PURPOSE:To make the coefficient of linear expansion with humidity of a film smaller and that in all directions on the surface of the film uniform and at the same time improve the widthwise change of a product film by a method wherein a specified simultaneous biaxial stretching is applied to a polyester film which is subjected to sequential biaxially stretching so as to have a specified birefringence. CONSTITUTION:First, polyethylene terephthalate is melt-extruded at 285 deg.C and then quenched so as to make a substantially amorphous sheet. Secondly, the resultant sheet is stretched lengthwise between a pair of nip rolls and cooling rolls which are located apart from the nip rolls by 2mm by one step, with the draw ratio of 3.2-3.3 and then cooled. Thirdly, the resultant sheet is stretched crosswise by the tentering method at 100 deg.C with the draw ratio of 3.1-3.5 and further continuously held at 100 deg.C for 5sec under the state that the width of the sheet is fixed and then cooled down to normal temperatures. Fourthly, the resultant biaxially stretched film is furthermore stretched with a simultaneous biaxially stretching tenter at 150 deg.C with the draw ratio in each direction of 1.5-1.7 and, after that, heat-set under tension at 200 deg.C. As for the polyethylene terephthalate film which is obtained by simultaneously biaxially stretching and then heat-setting a sequentially biaxially stretched film, smaller coefficient of linear expansion with humidity can be realized and the change in all directions on the surface of a film is realized to be made smaller.
