Title: Light source
Inventor: MOTOBAYASHI NAOKI
IPC: G03B27/54
Filed: 1990-10-24
Abstract: PURPOSE:To increase the light quantity to both side end parts by reflecting the light from those positions of a tubular halogen lamp, which are approx. at the tube ends but a little shifted toward the center and which have a large radiation intensity, to the tube ends through the action of the inclination of a reflex board. CONSTITUTION:A tubular halogen lamp 2 is equipped with a filament coil 5, wherein the radiation intensity is so designed and adjusted as enlarge in the positions 5a, 5b approx. at the ends but a little shifted toward the center. A reflex board 3 has approx. the same length as the lamp 2 and is equipped with a profile in a certain form - for example, U-form substantially-and the light from the lamp 2 is converged on the surface of a contact glass 21. The reflex board 3 is equipped with inclined parts in a certain form inclination-for example, in an arc of a circle - on the side opposite the lamp formed from the reflex surface from the positions at approx. the two ends somewhat shifted toward the center, and thereby the light from the positions 5a, 5b having a large radiation intensity is reflected to each end of the lamp 2. Thus the light quantity at the end parts can be increased without provision of any side reflector nor extending of the lamp 2 tube.

Title: Power converter in electric car with transmission
Inventor: YAMADA KATASHIGE
IPC: H02P21/00
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To provide comfortable regenerative control, regardless of the position of a gear in an electric car with a transmission. SOLUTION: A regenerative torque setting device has a plurality of regenerative patterns for generating a regenerative torque setting value corresponding to a detected motor speed so that comfortable power regeneration is provided in accordance with each gear position(GP) in a transmission(TM). In this case, the regenerative pattern is selected by a GP signal from a GP detector in the transmission(TM) to determine the regenerative torque setting value on the basis of the motor speed detected. Even when the gear position changes, a regenerative torque pattern is selected in accordance with the gear position to set a regenerative torque. Thus comfortable regenerative torque control is realized in accordance with the gear position.

Title: Method for laying out semiconductor integrated circuit
Inventor: MITSUMA YOKO
IPC: H01L21/82
Filed: 1993-11-17
Abstract: PURPOSE:To prevent the increase in size of a chip and to reduce a cell by making it possible to pass wirings on equipotential cell terminals, which are not used as base points for an outgoing wiring from the cell when preliminary wiring is performed. CONSTITUTION:Passing-wiring terminals 41, 45, 42 and 46, which determine the X coordinates for traversing a cell with aluminum passing wirings at the second layer, are drawn out at the center of the cell and generated at the upper and lower parts of the direction Y. In the design of preliminary wirings after automatic arrangement for determining the arrangement of the cell, the equipotential cell terminal 21 among a plurality of equipotential cell terminals 21, 22 and 23 is selected as a base point for the X coordinate of an outgoing line from the cell. Then, the passing wiring terminal 41 for the same X coordinate becomes usable, and the other passing wiring terminals 45, 42 and 46 become usable as the passing terminals. Thus, the passing wiring can be set at a position which cannot be used with a conventional technology, and the increase in chip size can be suppressed.

Title: Ultrasonic sensor
Inventor: TAKANASHI ISAO
IPC: G01S7/523
Filed: 1987-11-17
Abstract: PURPOSE:To make the sensor thin by providing ultrasonic wave transmitter receivers in the same direction and arranging their center of vibrations on the same plane and on the same circle. CONSTITUTION:A driving circuit 6 incorporates an oscillator and sends an electric signal intermittently to the ultrasonic wave transmitter receivers 1-4 which are connected in parallel. This output timing is controlled by a timing generating circuit 7 and the signal is radiated in the air by the transmitter receivers 1-4 at the same time. Further, the circuit 7 controls the driving of a receiving circuit 8 and outputs a driving signal to the circuit 8 for a predetermined time after sending the driving signal to the driving circuit 6, thereby making the transmitter receivers 1-4 ready to receive reflected electric signals from a body. In this case, the ultrasonic waves are out of phase and sound pressure is lowered except at the point where the ultrasonic waves sent by the transmitter receivers 1-4 coincides all in phase with one another. Consequently, the radiation range of sound pressure level is limited to a narrow range, directivity is obtained without using any horn, and the structure is reduced in size and thickness.
