Abstract: PURPOSE: To enable the remote supply of regenerative power by connecting a thyrister hybrid bridge including a parallel flywheel diode in series to a 3-phase full-wave rectifier with a diode in a current feeding for a DC electric railway system.  
     CONSTITUTION: At a DC feeding substation SS1, the secondary side of a transformer is connected to a diode 3-phase full-wave rectifier B and a thyristor 3-phase full-wave rectifier U combining a flywheel diode F in parallel whith is energized wuth the thyristor off while both rectifiers are connected in series. When the feeding current is below a specified value, the rectifier B is operated, while the rectifier U is operated when it is thereabove. This permits the feeding voltage to be set at such a low level free from trouble with an auxiliary device when light loaded, thereby facilitating the supply of regenerative power to an electric car existing at a remote location.

Filed: 1988-05-20
Abstract: PURPOSE:To obtain an inexpensive motor requiring no bearing member and bearing by arranging groove patterns for holding magnetic fluid at plural positions in the outer circumferential face of a fixed shaft. CONSTITUTION:Upon application of power onto a stator winding 15, a permanent magnet rotor 14 rotates and the magnetic fluid 20 existing between the groove pattern 19 of a fixed shaft 18 and a bearing hole section 14a is subjected to punping function of the groove pattern 19 to increase the pressure thus rotating the permanent magnet rotor 14 without contacting with the fixed shaft 18. Similarly, the magnetic fluid existing between the spiral groove in the under face 14b of the permanent magnet rotor 14 and a fixed flat board 16 is subjected to punping function to increase the pressure thus floating the permanent magnet rotor 16 above the fixed shaft 18 and rotating it without contacting with the fixed flat board 16. Since bearing member such as ball bearing or an oil seal for retaining lubricant is not required, number of motor parts can be reduced and the cost is reduced.

Title: Method for driving thin film el light emission device
Inventor: SATO YOSHIHIDE
IPC: H05B44/00
Filed: 1991-04-30
Abstract: PURPOSE:To suppress the ineffective drain current of an active thin film EL light emission device where EL elements are integrated to high density by precluding light emission due to the drain-gate parasitic capacity of thin film transistors(TFT) for turning ON and OFF the respective EL elements. CONSTITUTION:When a driving signal becomes minus, the TFT is turned OFF by synchronizing the phase of the driving signal which drives the EL element CEL with a control signal which perform light emission/nonemission control on the EL element CEL. Consequently, a charging voltage left in the parasitic capacity is minimized to prevent the gate voltage of the transistor from floating. The flotation of the gate voltage of the TFT is eliminated, so the TFT never turns ON unexpectedly. Further, the gate voltage is suppressed, so the ineffective drain current is reduced.

Abstract: PURPOSE:To keep the electrification potential of an electrostatic latent image carrier constant even if the volume resistance value of an electrostatic charging member is changed by environmental conditions. CONSTITUTION:The electrostatic latent image carrier 101 carrying an electrostatic latent image is provided, and the electrostatic charging member is disposed so as to be in contact with the electrostatic latent image carrier 101, to electrostatically charge the electrostatic latent image carrier 101. Therefore, a DC power source is connected to the electrostatic charging member, a direct current has constant current control, to supply the constant current to the electrostatic charging member, and even if the environmental conditions of a temperature, humidity, etc., are changed, and the volume resistance value of the electrostatic charging member is changed, the potential by the electrification is not changed. A destaticizing means is disposed on the downstream of a transfer device 111 and the upstream of the electrostatic charging member, in the rotating direction of the electrostatic latent image carrier 101. The destaticizing means removes a charge remaining on the electrostatic latent image carrier 101. Consequently, the potential by the electrification, of the electrostatic latent image carrier 101 is not unnecessarily made high by the repetition of the electrification.

Abstract: PURPOSE:To avert a lens from being transported in reverse form into the next process by installing a sensor for detecting the degree of elevation of a pin which moves vertically at a center of a material receiving part when the lens material is placed into a material receiving part and by judging the correctness of the obverse and reverse surfaces of the lens material. CONSTITUTION:In the state where a lens material 50 is closely attached onto a material receiving part 5 through vacuum suction the rod of a cylinder is moved upward, and a pin 56 is raised at the center of a material receiving part 51. In this case, if the lens material 50 is placed in the normally face-up state, a sensor 58 does not operate, and a check signal is not outputted, and the lens material 50 is transported to a curve generator. If the lens material 50 is placed in the reverse face-up state, the sensor 58 senses the permanent magnet 56a of a pin 56, and outputs a check signal. On the basis of the check signal, an alarm lamp and alarm buzzer are operated, and the fact that the lens material 50 is set inverted is informed to an operator.
