Title: Speaker
Inventor: NAKAGAWA YOSHIMORI
IPC: H04R9/00
Filed: 1995-04-13
Abstract: PURPOSE: To provide a coaxial two-way speaker having a short depth by arranging a speaker unit for high-pitched sound in the lower end or the center pole of a speaker for low-pitched and middle-pitched sounds and inserting a horen throat for high-pitched sound to the hollow center pole. CONSTITUTION: A through hole 36 is provided in the bottom of a shield cover 35 of a speaker for low-pitched and middle-pitched sounds (woofer) 2, and a speaker for high-pitched sound (tweeter) 3 is freely detachably arranged in the hollow part of a cancel magnet 37. Consequently, the depth of the speaker is shortened though the coaxial two-way speaker is constituted, and sufficient shielding is realized though a driver unit 50 of the tweeter 3 is not magnetically shielded. With respect to a horn throat 58, a conduction hole 28 is formed in a cylinder member whose outside diameter is fitted to the inside diameter of the hollow part of a center pole 5; and since throttling of this conduction hole 28 is relatively widely and properly selected, extension of the reproducing band and improvement of the tone quality are facilitated.

Abstract: PURPOSE:To reduce power consumption, to improve the efficiency and to decrease a switching time by devising the title circuit such that a 2nd transistor(TR) is energized when a 1st TR is saturated so as to limit the base current of the 1st TR. CONSTITUTION:A collector of an output NPN TR 1 being a 1st TR connects to a base of a PNP TR being a 2nd TR and a base of the NPN TR 1 connects to the emitter of the PNP TR 2. Then the saturating state of the NPN TR 1 is detected by the PNP TR 2 and the negative feedback loop limits the base current to the NPN TR 1, then the NPN TR 1 is restored to the ON state nearly equal to the saturation state from the over-saturation state while a sufficient load current is being supplied to a load 10. Thus, the power consumption is small, the efficiency is improved and switching time is quickened.

Title: Reclining device
Inventor: KANAI SHIGERU
IPC: A47C1/024
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To reduce the returning speed of a seat back by providing a friction spring which makes sliding contact with the inner peripheral surface of a cover to activate the seat back in the opposite direction to the activating force of a return spring. SOLUTION: When a seat back is inclined backward against the elastic force of a return spring 3, a friction spring 1 does not produce frictional forces against a cover 2 since its outside diameter W2 becomes smaller than the bore W1 of the cover 2, and the seat back can be adjusted to a desired position as usual. When the seat back is returned in the forwardly inclining direction by the elastic force of the return spring 3 which is stored by the backward inclination of the seat back, the outside diameter W2 of the friction spring 1 increases gradually and becomes larger than the bore W1 of the inner peripheral surface of the cover 2, so that the friction spring 1 makes sliding contact with the inner peripheral surface of the cover 2, increasing frictional forces.  Therefore, the returning speed of the seat back is decreased gradually by the frictional forces produced by the friction spring 1. The reclining device can be formed simply by providing the friction spring inside the cover of the return spring while directly using the components of a conventional device, thus resulting in reduced production cost.
