IPC: H01L23/29
Filed: 1986-03-05
Abstract: PURPOSE:To prevent the yield of cracks in a resin, by providing an elastic body layer, which surrounds a semiconductor integrated circuit element in a molding resin. CONSTITUTION:An elastic body layer 8 is provided so as to surround an IC element 5 and a mounting stage 3 directly. The outer surface of the elastic body layer 8 is packaged with a resin 7.

Filed: 1990-02-28
Abstract: PURPOSE:To increase the lifetime of a light emitting element by actuating the light emitting element of a photosensor kept in a card transfer path only when a detector detects that a card is out into a card processor. CONSTITUTION:When a card insertion detector 7 detects that no card exists between a light emitting element A and a light receiving element (a), the photodetecting signal of the element (a) is inputted to a control circuit 8. In the circuit 8, the level of the photodetecting signal is inverted and the base of a transistor TR of a power circuit 9 is set at H. Then the TR does not conduct and the light emitting elements B-D are not energized nor actuated. When a card is put between both elements A and (a), the light emitted from the element A is cut and the element (a) is turned off. As a result, the potential rises up between the element (a) and a resistance Rl so that the insertion of the card is detected. This detecting signal is inputted to the circuit 8, and the level of this detecting signal is inverted and the base of the TR is set at L. Then the TR conducts and the elements B-D emit the light respectively.

Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To increase the traveling distance in one battery charge, in a method wherein the gear transmission of an automatic transmission is controlled with the speed ratio which is the motor rotational speed as the gear ratio set value, an automobile is traveled at the transmission ratio at which the motor efficiency or the (motor + inverter) efficiency becomes maximum to automatically set the gear ratio of the automatic transmission at the value of maximum motor efficiency. SOLUTION: The motor rotational speed for each gear ratio of each transmission is calculated for the detected automobile speed, and the efficiency in each gear transmission is calculated from the torque command value and the motor speed using a (motor + inverter) map 21 for the rotational speed of a motor 2 and the torque. The motor rotational speed when the calculated efficiency becomes maximum is calculated, and the transmission ratio to obtain the calculated motor rotational speed is outputted as the set value. Because the gear ratio of an automatic transmission becomes the one at which the (motor + inverter) efficiency to the torque command value becomes maximum, an automobile is traveled in the condition where the (motor + inverter) efficiency becomes constantly maximum. Thus, the traveling distance in one battery charge is improved.
