摘要： A hand lever device for operating a driven member includes a main lever arranged to be pivoted about a first rotational axis, a sub-lever arranged to be pivoted about a second rotational axis and retained in a stationary state at a set pivoted position, a returning member arranged to be rotated about a third rotational axis, and a cable coupled at one end to the driven member and linked at the other end with the main lever and the returning member. When the main lever is pivoted to a set position, it rotates the returning member about the third rotational axis and removes slack from the cable. Pivoting of the sub-lever further rotates the returning member about the third rotational axis to a selected operating position. An accelerating subsidiary lever that is also pivoted about the first rotational axis further pulls, via the returning member, the cable, thereby to further move the driven member.

摘要： A sensor mechanism-equipped catheter is easy to produce, suitable for a diameter reduction, and achieves a high sensing precision. In a catheter, a sensor assembly has a pressure-receiving piston, a pressure-transmitting silicon gel or oil and a pressure sensor chip, and is fitted to a distal end of a catheter tube. The sensor assembly detects a pressure change. The sensor assembly further has an outer tube that carries the piston at a distal end side thereof, and an inner tube carrying the sensor chip an end side thereof. A space formed in the outer tube, between the piston and the sensor chip, is filled with the silicone gel or oil. A pressure barrier wall is provided for blocking flow of the silicone gel toward the catheter tube. The sensor chip is fixed in the sensor assembly by a joining member which divides an interior space of the sensor assembly into a distal end-side region and a base end-side region. The joining member may also serve as the pressure barrier wall.

摘要： A yaw rate detector and method of detecting yaw rate. The detector includes a sensor surrounded by a uniformly distributed gel-like material. The gel-like material is retained in a certain shape by a pair of parallel surfaces. The pressure of the gel-like material is affected by centrifugal force, which is sensed by the sensor. The sensor simultaneously detects pressure changes in the gel-like material on opposite sides of the sensor, which permits the detector to sense the angular velocity of rotation of the sensor. The sensor is a semi-conductor pressure sensor formed on a circuit substrate.

摘要： A control circuit outputs a first signal at a predetermined period in the case of being in a normal state and in the case of not being in a normal state, stops the output of the first signal at the predetermined period and outputs a third signal for controlling a motor on the basis of a second signal at a time when a switch SW is operated. In the case that the control circuit is not in a normal state, the first signal is not output at the predetermined period, a fifth signal is output from an output circuit and the second signal passes through a second gate circuit. Then, a drive circuit drives the motor by the second signal passing through the second gate circuit.

摘要： A transistor package includes a power bipolar transistor chip having a thermistor on and electrically connected to a bipolar transistor collector electrode. The thermistor exhibits a positive thermal coefficient (PTC) resistance characteristic and is series connected to the transistor collector. Collector current is interrupted by thermistor response to heat generated during excess transistor collector current events to thereby avoid thermal destruction of the device.

摘要： An accelerometer sensor is disclosed, utilizing a casing having a center axis, and a pressure sensitive element located at the bottom portion of the casing. A gel based medium is accommodated in the casing. Given that "x" denotes a positional deviation of the pressure sensitive element with respect to the center axis of the casing and that "h" denotes a height of the medium in the casing, the positional deviation (x) and the height (h) are set such that the value 2 x/h falls within a predetermined range and serves as a function of the anisotropic sensitivity ratio of the sensor.
