Title: Occupant crash protection device
Inventor: MOTOSAWA YASUKI
IPC: B60R21/02
Filed: 1999-12-06
Abstract: PROBLEM TO BE SOLVED: To provide an occupant crash protection deice capable of simultaneously compacting a car body dimension and reducing occupant deceleration in a higher degree. SOLUTION: This occupant crash protection device comprises a seat 1 that is supported movably in the direction of a force applied to a car body in a collision and includes a seat belt 3 for restricting a sitting occupant 2, a fluid vessel (a first fluid tank 14 in an embodiment) of which volume contracts with car body deformation during the collision, and a force generating means (a first cylinder device 5 in the embodiment) for applying a force to the seat back and forth in cooperation with fluid pressure filled into the fluid vessel that is generated by the volume contraction of the fluid vessel. When, for example, a progressing vehicle has a head-on collision, the fluid vessel provided for the front end of the car body crashes to feed fluid from the vessel to the force generating means such as a hydraulic cylinder.  At this time, backward acceleration is applied to the seat at the instant of the collision, and deceleration higher than car body deceleration is generated in the seat, so that constraint force of the seat belt for regulating forward movement of the occupant is increased.

Accompanying it, the PMOS transistor MP2 of the clamp circuit CLP is conducted and the output OUT of the output node HO1 becomes the high level. The NMOS transistor MN1 is normally ON since the substrate electrode BN1 is connected to the output node HO1.

Title: Air conditioner
Inventor: INOUE TSUNETOSHI
IPC: G01K7/00
Filed: 1993-12-27
Abstract: PURPOSE:To provide an air conditioner in which a temperature of an item to be measured can be accurately obtained irrespective of any short circuited trouble of a temperature sensor and thereby a stable and proper operation of the air conditioner can be carried out.

Title: Refrigerant compressor
Inventor: IZUMISAWA WATARU
IPC: F25B49/02
Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To reduce a pressure loss and a rise in a delivery gas temperature, and to suppress hunting operation by reducing a frequency of stagnating a bypass passage in a half-opened/half-closed state by smoothly performing operation of a piston type control valve. SOLUTION: For example, in a scroll compressor, a straight line-shaped cylinder 2 is formed in an end part of a sealed vessel 10 so that a piston type control valve 1 is movably arranged in the uniaxial direction on the inside of this cylinder 2. Passages 31, 32 and 33 communicated with compression space inside/outside parts are opened in the cylinder 2. When differential pressure between suction pressure Ps and delivery pressure Pd starts to be made after starting a compressor, the piston type control valve 1 starts to move in the direction for compressing a compression spring 7 since drag from a stopper 2g is not applied.  Excellently controllable/highly efficient operation can be performed since the piston type control valve 1 is put in a whole quantity operation state of an illustrated state when the differential pressure increases and to the contrary, is reliably put in a bypass operation state by passing through a half-opened state when the differential pressure reduces.

IPC: H01L23/50
Filed: 1993-12-22
Abstract: PURPOSE:To prevent deformation of outer leads, by forming a lead retainer which fixes the outer leads and retains them. CONSTITUTION:Outer leads 2a led out to the outside of a resin part 4 are formed into a gull wing form in order to be easily mounted on a substrate. As to a lead retainer 5, a gull wing form part 5a is formed in the peripheral part, and a flat face 5p is formed in the central part and fixed to a resin part 4 by using adhesive 6 or the like. Gull wing form parts 2a1 of the outer leads 2a are fixed to the gull wing form part 5a of the lead retainer 5, via adhesive 7 or the like.

Thereby a semiconductor package having high flatness precision of the outer leads 2a can be supplied.

As for a countermeasure at a recovery operation time after a power failure, a detection circuit 19 for detecting a voltage between output terminals 91 and 92 and generating an on-signal, when the detected voltage is over a given level, is provided. Then, an SID circuit 15 is inserted at a little earlier time by the signal, and after the output voltage is once reduced, an equalization charge mode is used to prevent an overvoltage of an output.  In addition, an AC input voltage is monitored, and by counting a logical AND, the operation is carried out only when the output of a power failure open-phase detector 75 is in an on-state.

Therefore, the inclined angle and inclined direction of an object to be detected attached with an inclination sensor 1 can be detected simultaneously in multiple directions.
