Title: Manufacture of ptc resistor and resistor manufactured by it
Inventor: RUCHIKA ROITOTSURU
IPC: H01B1/20
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To obtain a method for producing a PTC resistor exhibiting low resistivity and high current conductivity at a high temperature. SOLUTION: A polymer is admixed with a filler composed of a material having high electric conductivity and a resistor is made of the mixture. A substance having high glass transition point, melting point or crosslinking point, where PTC transition takes place only at 140 deg.C or above, is selected as the polymer. An oxidation resistant substance harder than carbon black or silver is selected as the filler. The filler is stocked in a low pressure or a nonoxidative atmosphere, especially in a protective gas atmosphere, and/or fused chemically before being mixed. Improvement in the properties of a PTC resistor thus produced can be achieved when the polymer is hardened or annealed in at least two temperature stages of the process for molding the resistor body part W.

Title: Structure of case for wall mounting device
Inventor: KOMATSU YASUSHI
IPC: F24H9/02
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To connect the inwardly bent flanges of a front face cover to the outwardly bent flanges of a back face plate without generating clearances by providing hemming parts formed by folding back free ends to the front surface sides of the outwardly bent flanges, on the outer edge parts of the outwardly bent flanges. SOLUTION: A back face plate 15 is formed by pressing a collar steel plate in the shape of a dish. Outwardly bent flanges 15a bent outward are formed on the right and left side edges of the back face plate 15. Upper and lower three stages of claw pieces 15b, 15c and 15d which extend forward are bent on the respectively outwardly bent flanges 15a. Hemming parts 15e formed by folding back free ends to the front surface sides of the outwardly bent flange 15a are formed on the outer edge parts of the respectively outwardly bent flanges 15a of the back face plate 15. The inwardly bent flanges 16a of a front face cover 16 abut against the hemming parts 15e of the outwardly bent flanges 15a at their base end parts.  Thus, the base end parts of the inwardly bent flanges do not float from the outer edge parts of the outwardly bent flanges 15a so that clearances, which can be visually observed from sides, are not provided between the back face plate and the front face cover.

Title: Phase locked loop circuit
Inventor: ITO YUICHI
IPC: H03L7/10
Filed: 1990-07-24
Abstract: PURPOSE:To reduce the time required for the synchronization of the phase locked loop circuit and to make a pull-in range broader by detecting an undesired period corresponding to a phase difference 3pi/2-5pi/2 in a triangle wave characteristic of a phase comparator and excluding the operation for the period forcibly. CONSTITUTION:An output signal of a VCO 3 is fed to a changeover circuit 5 through two paths for the noninverting output signal and the inverted output signal. On the other hand, a phase range detection circuit 6 receives an output signal of a triangle wave characteristic phase comparator 1 and detects whether or not a phase difference between both input and output signals is 3pi/2 and gives a control signal to the changeover circuit 5 when the phase difference reaches 3pi/2 to switch the connection to an output terminal 31 from the noninverting output of the VCO 3 into the inverting output. Through the control, the phase difference region against the control direction required for pull-in is transited forcibly to the phase difference region in the forward direction of pull-in and the time required for pull-in is reduced and pull-in range is widened.

Title: Holding circuit for stepping motor
Inventor: NARAI KYOICHI
IPC: H02P8/00
Filed: 1990-07-24
Abstract: PURPOSE:To eliminate wasteful consumption of energy during holding by providing a switch to be closed in a holding state to circulate a current in a coil by a counterelectromotive force generated by the rotation of a shaft. CONSTITUTION:Signals COMMON A, COMMON B are set to a low level in a holding state, transistors Q5, Q6 are turned OFF, and switches SW1, SW2 are closed. Since a stepping motor 1 is connected to a power source only through the transistors Q5, Q6, an external current is not fed to the motor 1 by the OFF of the transistors Q5, Q6. However, when the shaft of the motor 1 is applied externally by a force to be rotated, counterelectromotive forces are generated in the coils 2-5 of the motor, and currents are circulated through the coils via the switches SW1, SW2. When the currents flows to the coils 2-5, a magnetic field is generated at the periphery of the coil, and the shaft of the motor 1 is strongly held.

Title: Route guiding device for vehicle
Inventor: YOKOYAMA SHOJI
IPC: G01C21/00
Filed: 1992-07-23
Abstract: PURPOSE:To perform operational explanation in voice at a desired timing. CONSTITUTION:A display part 28 in an input part 18 is a touch panel and the various kinds of input are performed by touching a display. For instance, the setting of a destination and the memorizing of a prescribed location, etc., can be performed by touching the display of the display part 28. Since the input performed while touching the display is different at every display screen, there are cases that an input method is not known. Therefore, the operational explanation is performed in the voice. Especially, only when no input is performed even after the lapse of a prescribed time (7 seconds, for instance) in the state of waiting for the input, the operational explanation in the voice 15 performed. Thus, even when an experienced person is operating a device, the operational explanation in the voice can be prevented from being felt as troublesome.

Abstract: PURPOSE:To obtain a GTO thyristor which is increased in a current by forming a gate current collecting electrode plate in a ring shape at the intermediate of multiple rings of a cathode side emitter layer, thereby equalizing the operation of a plurality of unit GTO elements. CONSTITUTION:A cathode side emitter layer 5 is disposed radially, for example, in quintuple rings from the center of a cathode side emitter layer 5, and a gate current collecting electrode plate 80 is provided at the intermediate between the third ring and the fourth ring.
