Title: Vibration isolating device wiring structure
Inventor: MATSUDAIRA MINORU
IPC: G06F1/18
Filed: 1992-06-26
Abstract: PURPOSE:To prevent a cable from being broken and a frictional force from increasing by suppressing displacement outside a plane by bundling a wiring part which is displaced or fixing it to a dedicated fixation plate. CONSTITUTION:A computer 4 is installed on the vibration isolating device 3. The vibration isolating device 3 is displaced by up to 600mm in the case of an earthquake and cables 1 which are connected thereto are laid in a U shape for displacement absorption. At this time, the cables 1 are bundled and mutually fixed. The cables are grouped and fixed and then they are mixed up disorderly, so an excessive force is prevented from being applied to only one cable at the time of movement. When the cables are only bundled, they can not be prevented completely from moving out of the plane, so the cables are fixed by using the fixation plate 5. Consequently, the breakage of the cables and an increase in frictional force can be prevented.

Alternate load is applied to the wall-removed part 17, and the first teeth portion 13 is broken at the wall-removed part 17 to separate it from the base metal 11. Thereafter, the second teeth portion 15 appears at an outer peripheral part of the base metal 11 to cut an object to be cut.

Title: Overrun preventing device of motor for driving electric motor vehicle
Inventor: NAKAMURA MASASHI
IPC: B60L3/08
Filed: 1985-07-30
Abstract: PURPOSE:To prevent a driving motor from overunning by suppressively controlling the output torque of the motor when the speed of the motor exceeds an allowable speed. CONSTITUTION:Suppressing amount calculating means 30 outputs a calculated value T2 in response to a difference between a detecte speed N and an allowable speed Nmax. A comparator 34 outputs a signal of H level when the speed N exceeds the speed Nmax. A gate circuit 36 outputs a torque suppressing amount T2 to a subtractor 38 when the torque suppressing command of H level is input from the comparator 34. The subtractor 38 subtracts the torque command value T1 and the amount T2, and outputs the subtracted value T3 to a motor driving circuit 12 as a torque command value. Thus, it can effectively prevent a motor from overrunning.

Title: Surface treatment of ferrous metallic parts
Inventor: KASHIDA AKIRA
IPC: C23C8/56
Filed: 1982-09-30
Abstract: PURPOSE:To prevent the generation of the blown-out matter after mechanical removal of the infiltrated matter, by subjecting porous ferrous parts to a surface treatment by a nitriding treatment with a salt bath then heating the same to a specific temp. to blow out forcibly the infiltrated matter and removing mechanically the same. CONSTITUTION:A hard nitride layer is formed by a nitriding method with a salt bath on porous metallic parts such as ferrous sintered parts in order to improve the wear resistance thereof. Since the salt in the bath used in this case is infiltrated into the inside of the porous material, the parts are heated for 30- 60min at 200-300 deg.C to blow out forcibly the infiltrated matter onto the surface. The blown-out matter is thoroughly removed by shot blasting or shot peening. The generation of the succeeding blow-out is thoroughly prevented by such treatment, and the surface hardness of the sintered parts is further improved by a peening effect as a secondary effect.

Title: Power supply device
Inventor: LIANG JIM H
IPC: H02M7/06
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To provide a power supply device provided with a circuit which improves input power factor effectively. SOLUTION: A coil La and a diode D1 are connected in series between a bridge rectifier DB1 and the positive pole of an electrolytic capacitor C1. A coil Lb is connected in series between the positive pole of the electrolytic capacitor C1 and a DC-DC converter. The use of the same iron core Tr1 in the two coils La, Lb enables the diode D1 to be changed over to a positive or reverse bias state when the polarity of both coils is controlled. An AC power supply Vs1 introduces an input current Iin in any phases of the sine wave. As a result, the DC ripple voltage Vdc of the electrolytic capacitor C1 is not only low, but the output end of the DC-DC converter is not affected by the AC of 120 Hz. Therefore, the power factor of the input power source of a power supply device improves effectively and in turn its power performance and quality improve.

Filed: 1988-07-08
Abstract: PURPOSE:To supply a stable voltage by providing a constant-voltage circuit for outputting a constant-voltage as a first power supply voltage, and a boosting circuit for outputting a boosted voltage as a second power supply voltage. CONSTITUTION:A switch 4 is turned ON, an STB operates, a voltage VSTB which is stabilized to about 1.5V is outputted from the STB, switch 5 is turned ON, and a VSS1 system becomes a VSTB level. Subsequently, is switch 6 is turned OFF and a battery voltage is cut off from a VSS2 system. When ON/OFF of switches 7, 9, and ON/OFF of switches 8, 10 are interlocked and repeated alternately, a level of the VSS2 system is boosted to a voltage of two times the voltage of VSS1=VSTB. In this case, a control signal CL1 is a signal for switching whether the battery voltage is applied directly to the VSS2 system, or a voltage which is converted to a constant-voltage by operating a constant- voltage circuit is applied to the VSS1 system, and becomes the former application or the latter application by HIGH level or LOW level, respectively. In such a way, the constant-voltage circuit operates and a stable voltage is obtained, and oscillating, frequency dividing, and fundamental logic parts are operated.
