Title: Synchronizer device for transmission
Inventor: TAKAGI IZUMI
IPC: F16D23/06
Filed: 1986-03-17
Abstract: PURPOSE:To increase the synchronizing capacity, by forming a tapered friction surface on the internal periphery of a synchronizer ring, which integrally rotates with a clutch hub, to be opposed to the peripheral tapered friction surface of a synchro cone and arranging an intermediate cone between the above described ring and cone. CONSTITUTION:In a condition that an input gear 2 rotates while with a main shaft 1 and hub 5 not rotating, if a sleeve 6 moves in a direction F in the driving, a strut 17 also moves in the direction F removing a recessed part 6a from a protrusion 17a in the direction F, and positioning is performed so that a sleeve side chamfer part 31a and a chamfer part 27 of a ring 13 are opposed to each other. A movement of the sleeve 6 is blocked by the ring 13, and this blocking force acts as friction torque. The friction torque is generated between an internal peripheral friction surface 26 of the ring 13 and the peripheral surface of a separator cone 21, between the internal peripheral surface of the cone 21 and the peripheral surface of a friction cone 20 and between a tapered friction surface 22 of a synchro cone 12 and the internal peripheral surface of the cone 20, and the synchronizing capacity very large increases.

Abstract: PURPOSE:To recognize the movement of an object with high accuracy by moving a focus area in a succeeding frame by several surrounding blocks each and using an area having a block whose focus quantity is a peak as a new focus area. CONSTITUTION:A focus area control section 8 outputs a command to move one surrounding block each of a focus area in a succeeding frame. A memory control section 9 receives a focus area moving command and controls the read of a picture data of the focus area after the movement in the picture data stored in a frame memory 4. An orthogonal transformation section 5 implements orthogonal transformation for each block with respect to a picture data fed from the memory 4. A focus quantity detection section 6 detects the focus quantity and sets a focus area having a block whose focus quantity is peak as a new focus area. Then a focus motor control section 7 outputs a control signal.

Title: Display for electronic balance scale
Inventor: FUJINAGA YASUHIRO
IPC: G01G19/62
Filed: 1985-03-25
Abstract: PURPOSE:To enable efficient balancing work, by comparing a measured value with a weighing target value to display the degree of difference, excess or shortage, above or below the lower one and two digits of a digital display with a bar. CONSTITUTION:When a weighing target value is previously inputted through an input means, a bar display is done below the lower one or two digits according to the difference on a digital display until the measured value reaches the target value and a sign of insufficient weighing is sent to a worker. When the measured value exceeds the target value, a sign of overweighing is sent by displaying the same digit with the upper bar. This allows a worker to determine the state of the plate load with respect to the weighing target value simply by viewing the lower one and two digits of the display. Thereafter, even an unskilled worker can carry out an efficient work by adjusting the feed value properly.

Title: Baking of gas laser oscillator
Inventor: OGURA YASUHIRO
IPC: H01S3/097
Filed: 1990-03-13
Abstract: PURPOSE:To enable air and moisture attached inside an oscillator tank to be rapidly removed by a method wherein a cooling means provided inside the oscillator tank is lessened in cooling capacity and a baking current is made small at the rise time of a gas laser oscillator. CONSTITUTION:Laser gas 11 rising in temperature due to the discharge in a discharge section 1 is cooled down by a heat exchanger 10 which serves as a cooling means and recirculated. At this point, the heat exchanger 10 provided inside an oscillator tank 3 as a cooling means is set lower than usual in cooling capacity. The heat exchanger 10 is lessened in cooling capacity through such a way that cooling water sent into the heat exchanger 10 is lessened in volume by an adequate quantity. Therefore, the laser gas 11 increased in temperature due to the discharge occurring inside the discharge section 1 does not fall so much in temperature even after it passes the heat exchanger 10. The laser gas 11 is made to circulate inside the oscillator tank 3 and returns again to the discharge section 1 keeping high in temperature. Therefore, laser gas can be kept high in temperature at a B section without making a large current flow, so that air, moisture, and the like attached inside the oscillator tank 3 can be efficiently removed independently of parts where they are attached.
