Abstract: PROBLEM TO BE SOLVED: To maintain a speech between a mobile station and a stationary station radio equipment even when any of the stationary station radio equipments is out of order due to a fault or the like by connecting another channel from a repeater to a controller. SOLUTION: A stationary station radio equipment 4 and a base station radio equipment 2 detect a squelch voltage respectively by the transmission from the radio equipment 4 or the mobile station 1. Through the detection of the squelch voltage, the radio equipment 4 excites the transmission of a radio equipment 2 via a repeater 3 and on the contrary, when the radio equipment 2 detects the squelch voltage, the transmission of the radio equipment 4 is started via the repeater 3.

Title: Magnetic tape
Inventor: ICHIJO MINORU
IPC: C09D175/04
Filed: 1989-06-05
Abstract: PURPOSE:To obtain a magnetic tape excellent in corrosion resistance by specifying the eluted amt. of acid content in the powder incorporated into a back coating material to be used to form a back coating layer. CONSTITUTION:The eluted amt. of acid content in the powder in the back coating material used for the back coating layer is specified to <=500ppm. Since the powder to be incorporated into the back coating layer 4 is subjected to surface treatment such as acid washing to improve its dispersibility in the coating material and adhesion property to a binder, it is supposed that a small amt. of the acid remains in the powder and promotes corrosion in the magnetic recording layer. Therefore, it is required that the eluted amt. of acid reamining in the powder is <=500ppm.

IPC: H01L21/60
Filed: 1988-06-09
Abstract: PURPOSE:To enhance the productivity of semiconductor device by reducing the dispersion in the shape of bump type electrodes and the manufacturing processes by a method wherein the second manufacturing process to bury the bump type electrodes in a substrate is performed independently from and in parallel with the first manufacturing process to bond the bump type electrodes onto the substrate surface while the level of the bump type electrodes and the plane shape are prescribed by the depth and the shape of the burying holes formed in the substrate.

Title: Steering controller for vehicle
Inventor: KOZUKA HAJIME
IPC: B62D7/18
Filed: 1989-06-05
Abstract: PURPOSE:To improve the reliability of the title device with a simple structure by transmitting the vertical displacement of a suspension arm to a knuckle arm length variable mechanism by means of a link mechanism so as to make a knuckle arm length variable. CONSTITUTION:As a suspension is stroked in the damping direction BM, a lower arm 3 is turned upward around a point B so as to increase an angle between the lower arm 3 and the lower arm part 1a of a knuckle 1, thus increasing a distance between a ball joint 45 and a rotor shaft 41. This causes the displacement of the lower arm 3 to be transmitted to the rotor 42 through the ball joint 45, a car height detecting link 46 and a ball joint 43, to thereby turn the rotor 42 downward around a shaft 41. Accordingly, an auxiliary link 24 is turned through a control link 26 so as to extend the length R of a knuckle arm. With this arrangement, it is possible to improve the reliability without an electronic device.

Title: Circuit for driving electric motor
Inventor: UMA GIYOUOU
IPC: H02P7/29
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To provide a motor driving circuit small in energy loss where a small- sized feedback coil can be used. SOLUTION: This circuit has a switch element 10 which applies a current to a motor coil 11, a capacitor 13 which accumulates the energy of the motor coil 11 through a diode 12, a switch element 14 which feeds back the accumulated energy to power sources 20 and 21, a feedback coil 16, and a feedback diode 15. This driving circuit is equipped with an accumulating capacitor voltage detecting means 91, feedback current detecting means 18 and 95, and a feedback control circuit 9 which turns off the feedback switch 14 when the feedback current is high. When the voltage of the accumulating capacitor is high and besides the feedback current is low, this turns off the switch element 14. This makes the detected current binary, and converts the detected voltage into PWM pulses, and switches the feedback with the AND of both.  This determines the binary threshold of the detected current with detected voltage.
