Title: Method for bending bar extruded shapes such as trolley bar
Inventor: KUSHIGE YOSHIHIKO
IPC: B21D3/10
Filed: 1988-01-26
Abstract: PURPOSE:To easily bend a bar shape by changing an average crystal grain size between one part and the other part of a section at right angles with an extruding direction to form an extruded shape and pulling and straightening it in the length direction. CONSTITUTION:A shape 1 is extruded so that the average crystal grain size is larger in one part A than in the other part B of a section at right angles with the extruding direction of the shape 1. After the extruded shape 1 is cooled, a tensile strain is added by a pulling and straightening equipment in a length direction and then the tension state is released. The quantity of spring back is larger in the other part than in one part A and, accordingly, the shape is bent and deformed in the form of a circular arc. In this way, the bar extruded shapes such as trolley bars can be bent inexpensively and easily.

Abstract: PURPOSE:To improve stopping characteristics and forward direction conductive characteristics compatibly by forming a gate region, which is buried tabularly while being separated into a base layer, in impurity concentration and thickness within a predetermined range in the electrostatic induction type thyristor. CONSTITUTION:A P<+> anode layer 1 is diffused to one surface of a substrate such as an N<-> substrate 10 having 50OMEGAcm resistivity, and a P type gate region 4 is diffused and shaped within the ranges of 10<18>-10<19> surface concentration and 2-15mum depth from the other surface. An N type epitaxial layer 3 having 2X10<15>cm<-3> impurity concentration is deposited, P type connecting regions 5 reaching the region 4 and N<+> cathode layers 6 are diffused, electrodes 7-9 are formed, and an element is completed. A depletion layer can easily be expanded to the channel region side, width D is increased, and the forward direction conductive characteristics can be improved by setting the gate region 4 within said range. Turn-off characteristics can also be ameliorated because the resistance in the lateral direction of a gate can be minimized. Current capacity and breakdown resisting quantity can be improved because main currents are also flowed sufficiently through the gate region.

Title: Position detecting method
Inventor: MIYAZAKI HIROMICHI
IPC: G01S15/66
Filed: 1983-02-04
Abstract: PURPOSE:To simplify a measuring method and to raise the measuring accuracy by measuring an arrival time at the optional three fixed points of an ultrasonic wave transmitted from an object to be measured by a command signal from a command operation part, operating and processing a counting value to obtain the position of the object to be measured. CONSTITUTION:First of all, a transmitting command is outputted to a CPU21 and a radio wave is transmitted from a main antenna 23. When its radio wave is received by a radio wave receiver 12 of an object to be measured 1, an ultrasonic wave transmitter 13 is operated to transmit an ultrasonic wave from a loudspeaker 14. At the same time, the command operating part 2 transmits a count start command to each counter 36 of fixed points A, B and C, to start the counting of the time required for receiving the ultrasonic wave. Since the ultrasonic wave is non-directional, each ultrasonic wave receiver 34 counts exactly the arrival time of the ultrasonic wave, operating a range to the object to be measured 1 independently at each fixed point by a sub-CPU35, and transmits it to a main CPU21. The main CPU21 executes a coordinate operation, and detects the position of the object to be measured after the calibrating work. In this way, the measuring method is simplified to raise measuring accuracy.

Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent fine foreign matters from cutting between the opening edge of a relief port and a poppet in a poppet valve type relief valve with no use of a strainer. SOLUTION: A sleeve 3 is constituted of a sleeve body 20 and an auxiliary sleeve 22. The auxiliary sleeve 22 defines a minute clearance gap 31 between its outer periphery 25 at the smaller-diameter tip and a bore 2 formed through a valve body 1 to permit through the gap 31 the inflow of high-pressure fluid on the side 7 of higher pressure into a relief port 8 defined inside the sleeve body 20. That minute clearance gap 31 strains fine foreign matters away from the high-pressure fluid to prevent them from getting in between the opening edge 8a of the relief port 8 and a poppet 9.

Abstract: PURPOSE:To improve operatability by lifting a working device up to a prescribed level by means of a forced lifting switch, and at the same time by operating a speed change device to a stored speed change stage by a priority control means prior to the speed change stage by a vehicle speed setting mechanism. CONSTITUTION:By the operation of a forced lifting switch 27 for lifting a working device up to a prescribed level, the lifting of the working device can be achieved, and at the same time a priority control means C operates a speed change gear A to the speed change stage previously stored in a storing means M, prior to the speed change stage having been input by a vehicle speed setting mechanism 29 via a control means B. Thus, only by operating the single switch 27, a desired vehicle speed having been previously selected can be obtained, and especially by commonly using the switch 27 for operating the priority control means C for a switch of the other purpose, the operation for obtaining the desired vehicle speed can be simplified.

Title: Transmission method for alarm tone or the like of selective call receiver
Inventor: SAKO KAZUNARI
IPC: H04W84/02
Filed: 1985-01-31
Abstract: PURPOSE:To discriminate easily the display of alarm tones, etc. due to a hit of the power supply from the display performed based on a normal call, by actuating a display means like an alarm, etc. based on each working time prescribed previously to the selective call or the application of the power supply. CONSTITUTION:When a power supply application signal is supplied to a ring tone control circuit 6, a timing circuit 3 starts counting and a drive signal is delivered to an amplifier circuit 7. A timer counts up for 5sec, for example, and the output of the drive signal stops. An alarm tone lasts for the output of the drive signal to turn on a light emitting diode 9. Then a selective call signal is supplied to a waveform shaping circuit 1 from a demodulation circuit 20. Thus the circuit 6 is driven. The drive time lasts for a prescribed time of the 1st timer circuit 3b of the circuit 3, e.g., 30sec. If the drive signals are delivered from the circuit 6 for said drive time, a speaker 8 and the diode 9 are actuated via the circuit 7 for generation of alarm tones as well as the lighting display.
