Title: Individual selective calling receiver
Inventor: MORISHIMA MASAAKI
IPC: H04W84/02
Filed: 1990-11-26
Abstract: PURPOSE:To prevent the service life of a battery from being shortened due to the turning on a first switch 1 while this receiver is carried and activating a LCD display device by prohibiting the interruption of a second switch with the interruption of the first switch. CONSTITUTION:When a power supply switch 13 is slid to a locking position, a terminal S5 is switched from high to low. Then a control part 21 detects this change, prohibits the interrupting on by push button switches 11, 12 and locks the switches 11, 12. Consequently, this receiver prevents a risk to shorten the service time of the battery due to turning on the push switch accidently while this receiver is carried and activating the LCD display device unnecessarily to light a back light.

Title: Variable compression ratio mechanism for reciprocating engine
Inventor: KASHIYAMA KENJI
IPC: F02D15/02
Filed: 1988-12-15
Abstract: PURPOSE:To improve the responsiveness by operating a lock pin for positioning an eccentric piston pin by the inertia force of the lock pin and carrying out the assistance on switching the compression ratio and the holding of the eccentric position after switching by a hydraulic pressure. CONSTITUTION:When the compression ratio is selected, the hydraulic pressure acting onto a lock pin 9 is set into OFF-state by a control valve 15 in the vicinity of the bottom dead center of a piston. Since the inertia force of the lock pin 9 acts downward, the lock pin 9 deflects from the outer peripheral side pin holes 7 and 8 and is set into an inner peripheral side pin hole 6, and a piston pin 3 is set free in the turning direction for a connecting rod 5. In the switching from the high compression ratio to the low compression ratio, the hydraulic pressure is returned to the ON-state in the vicinity of the top dead center in compression, and the piston pin half revolves, and is set to a low compression ratio position, and the lock pin 9 is engaged with a pin hole 7, and the piston pin 3 is fixed at the low compression ratio position. In the reverse switching, the hydraulic pressure is returned to ON-state in the vicinity of the top dead center in intake. Thus, the superior responsiveness is obtained, and the compression ratio can be varied.

Title: Device for locking vehicle seat
Inventor: HANSUUYOAHIN BERUKUHOFU
IPC: A47C1/025
Filed: 1990-11-26
Abstract: PURPOSE: To lock a seat back without backlash by rotatably supporting a claw member on an eccentric member, and providing a rotational mechanism for rotating the eccentric member to the unlocking position before the oscillating operation of the claw member and for rotating the eccentric member to the locking position after the oscillation operation of the claw member. CONSTITUTION: When tensile force does not applied to an eccentric member 11 by a tension rope 22 (a rotational mechanism), the member 11 is firstly rotated by a tension coil spring 12, a hook (a claw member) 9 is locked on a pin member 8 with backlash. When the member 11 is further rotated against spring force of the tension coil spring 17, the hook 9 is moved to the unlocking position by an interlocking pin 15. When the member 11 is further rotated after the hook 9 reaches the position in which it is completely locked by the member 8, the interlocking pin 15 is lifted from a nose part 16. By this rotational motion, backlash between the hook 9 and a pin 10 is completely eliminated.

IPC: F42D5/045
Filed: 1990-11-26
Abstract: PURPOSE:To permit the reduction of ground vibration propagated to environment without damaging an exploding chamber and/or an explosion vibration reducing device by a method wherein a trestle, supported by an elastic supporting body and having a big weight, is provided in the exploding chamber and explosive is exploded on a shock attenuating member provided on the trestle. CONSTITUTION:At first, a trestle 6, supported by an elastic supporting body 4 and having a big weight, is provided on the bottom of an exploding chamber 1. A shock attenuating member 7 is put on the trestle 6 and explosive or the like 8 is exploded on the shock attenuating member 7. When the explosive and the like 8 is exploded on the trestle 6 in such a manner, vibration is generated in the trestle by collisions between blast and material vessel while the vibration is propagated to the bottom of the exploding chamber 1 and ground from the trestle 6 through the supporting body 4. In this case, the trestle 6, constituted of a material having heavy weight, is put on the supporting body whereby the moving speed of the trestle 6 due to the shock of explosion of the explosive and the like 8 is slowed down and the vibration can be reduced. On the other hand, the shock attenuating member 7 is deformed, broken down, scattered to the circumference thereof and the like by itself and the kinetic energy of the material vessel and the energy of the blast are reduced whereby the blast is weakened and the shock speed of the material vessel is reduced thereby permitting the remarkable elongation of the life of the trestle.

Title: Thin film magnetic head and its manufacture
Inventor: KONDO REIKO
IPC: G11B5/39
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To provide a thin film magnetic head low in cost, high in reliability and used for a magnetic disk device. SOLUTION: In this thin film magnetic head, the direction of a magnetic domain when a medium magnetic field does not exist is lined up in a prescribed direction without using a magnetic domain control film by forming a magneto- resistance effect film, which has a function changing the direction of the magnetic domain in response to a medium magnetic field, into a prescribed shape. In such a manner, since the magnetic domain control film is not used in the thin film magnetic head, the process is simplified, and also variance of a magnetic characteristic in the magnetic control film and variance of a head characteristic owing to magnetic variance or the like of a contacting part between the magneto-resistance effect film and the magnetic domain control film are eliminated.
