Inventor: MIYAGAWA KIYOSHI
IPC: B32B5/00
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To provide manufacturing method of a pressure vessel capable of securely preventing the turbulence of orientation of fibers at the end part of a reinforcement for manufacturing an FRP pressure vessel which is provided with a roughly hemispherical dorm part with an opening part at its center and annular reinforcement coaxially with the opening. SOLUTION: In a manufacturing a pressure vessel, a fiber layer is formed on a mandrel corresponding to the inside form of the pressure vessel (motor case 1), a reinforcement 9 in which at least the end part on the large diameter side is formed in an outward tapered surface 9a is formed and, after the reinforcement 9 is overlapped on the surface of the fiber layer, another fiber layer is formed on the surfaces of the fiber layer and reinforcement 9. Thus fibers passing over the end part of the reinforcement 9 are not bent, and the strength of the fibers is prevented from lowering due to the turbulence of orientation of fibers.

Title: Gas generator
Inventor: TAGUCHI MICHIHISA
IPC: B60R21/33
Filed: 1993-07-07
Abstract: PURPOSE:To improve the reliability of ignition and prevent wrong explosion by energizing an ignition pin, flying being triggered by an inertia body moving upon detecting the deceleration of a vehicle, by spring force, igniting ignition chemical by supplying voltage from a piezoelectric element in association with the collision of the ignition pin, and making static electricity escape from an ignition means by a electrification preventing means. CONSTITUTION:Upon the collision of a vehicle, an inertia body B moves in a direction 43 and presses the tip part of a trigger lever 42 to rotate it, and the hook part 36b of an ignition pin 36 comes off a rotor 42a, so that the ignition pin 36 flys in a direction 44 by the energizing force of a compression spring 27 and collides with a piezoelectric element 30. Piezoelectricity is thereby generated to the piezoelectric element 30, and an electric discharge plug 34 discharges in a space to a center disc 19, thereby igniting ignition chemical 17. The ignition pin 36 thus ignites the ignition chemical 17 positively by the compression spring 27. Also, since a resistance 35 is provided between the electric discharge plug 34 and earth, static electricity escapes through the resistance 35 so as to prevent electrification.

Title: Piezoeleotric element drive circuit
Inventor: OUCHI YOSHIHITO
IPC: H01L41/09
Filed: 1990-07-20
Abstract: PURPOSE:To increase the degree of freedom of circuit characteristics setting by installing a transformer with a primary-side coil connected to a dc and a secondary-side coil connected to a piezoelectric element and switching devices each placed between the primary-side coil and a dc and between the secondary- side coil and the piezoelectric element respectively. CONSTITUTION:The maximum current I1p induced in a primary-side coil 31 is proportioned to the time t1 during which a switching transistor TR1 is held 'on'. The moment a TR2 is turned 'off' and the current >=1 of the coil 31 turns from I1p to zero, an induced current 12 is induced in a secondary-side coil 32. The induced current 12 is the maximum value I2p first but it turns to zero after the passage of the time t2 and so a piezoelectric element 2 is charged. When the TR2 is held 'on' for the time 't' until a difference in potential Vc between both ends of the piezoelectric element 2 becomes zero, the current 12 flows in the coil 32 and the moment the TR2 turns 'off', the induced current 11 is induced in the coil 31 and is regenerated to a dc supply 1 through a diode 33. Consequently, the power consumption can be kept low.
