Title: On-vehicle position measuring system
Inventor: ISHIKAWA SEIJI
IPC: G01C21/00
Filed: 1993-03-17
Abstract: PURPOSE:To make it possible to measure position of a vehicle even if the number of available satellites is insufficient by determining the relative speed between a satellite and the vehicle based on the frequency of a signal transmitted from the satellite and the frequency of an actually received signal. CONSTITUTION:Radio wave from a satellite is received through an antenna 10 by a receiver 11 and fed through a demodulator 12 to an information processing unit 16. The unit 16 generates information (latitude, longitude, altitude) representative of the position of vehicle based on the information received from the satellite and presents the information thus generated on a display 13. Since the position of vehicle can be calculated even if the number of satellites is insufficient, relative speed between the vehicle and the satellite can be determined from the frequency of signal transmitted from the satellite and the frequency of an actually received signal. Position of the vehicle is then calculated from the information received from available satellites rotational angular speed (advancing direction) of the vehicle outputted from a piezoelectric oscillation gyro 1, and the relative speed. Since relative speed is utilized, no vehicle speed sensor is required.

Title: Chuck mechanism
Inventor: HIRANO TOMOYUKI
IPC: B25J15/08
Filed: 1992-02-10
Abstract: PURPOSE:To reduce the load to an electric motor and improve the life of the electric motor by interposing an elastic body in a part of at least one finger. CONSTITUTION:When a cam C is rotated by the drive of an electric motor M, each roller 6 is rolled along the circumferential surface of the cam C, and each finger F1, F2 pivotally supported on a base is oscillated to make opening and closing operation. When each roller 6 is rolled to the short diameter position of the cam C to the long diameter position, each finger F1, F2 is transferred from opened posture to closed posture. When the fingers F1, F2 make contact with a material to be nipped during this, an elastic body 7 interposed in a part of each finger F1, F2 is curved. The material to be nipped is held by each finger by the restoring force of the elastic body 7, and each roller is energized toward the rotating center of the cam. This energizing force never form the force for rotating the cam, and thus, the holding posture of the material to be nipped is continued even if the electric motor is stopped to lay the cam in free state.

IPC: F28F1/32
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To enable the expansion of a heat transfer pipe in a true circle when a fin and a heat-transfer pipe are to be bought into close contact by setting higher a fin that opposes the welded part of the pipe sectional surface inner periphery of a welded heat transfer pipe with inner surface groove where a welded part exists in the inner periphery of the pipe or a fin near it as compared with other fins. SOLUTION: In a welded heat transfer pipe 7 with inner surface groove used for the heat exchanger of an air-conditioning equipment, a fin part (a) that opposes a welded part 73 of a pipe sectional area inner periphery or a fin part near it is formed to be higher as compared with a height h1 of other fin parts (b). In this manner, since the fin part (a) that opposes the welded part 73 or a fin part near it is higher than the other fin parts (b), so that the pipe 7 spreads in nearly genuine circle when the heat transfer pipe 7 is expanded by a plug, thus preventing a gap from being formed at a junction part 6 between an aluminum fin 5 and the welded heat transfer pipe 7 with inner surface groove and hence eliminating a problem for collapsing the sharp and high fin due to the excessive spread of the pipe for burying the gap.

Abstract: PURPOSE:To improve the withstand voltage for an external surge voltage by connecting part of the control electrode of an output transistor with the prescribed potential for setting the transistor in the portion in nonconductive state. CONSTITUTION:When a surge voltage which exceeds the withstand voltage of an output transistor Q1 is applied externally if output transistors Q1, Q2 are in nonconductive state, the surge voltage is applied from metal wirings 14 connected with an output terminal 21 to transistors Q1, Q3 is flowed through the channel of the gate electrode 12 for driving the transistor Q1 to its source, but also flowed simultaneously to the channel of the gate electrode 13 of the protecting transistor Q3 fixed to the ground potential. Accordingly, as a result, a current amount per unit channel area is reduced, and the terminal 21 is endured for a larger surge voltage. Thus, the current amount flowed per unit area of the output transistor reduces to improve the protecting function of the output terminal.
