Abstract: PURPOSE:To reduce the distortion and to eliminate the need for the temperature compensation of an idle current, by detecting the idle current and the distortion component at the same time from an error amplifier and an output resistance circuit network provided correspondingly to each amplifier element of the emitter follower SEPP constitution and feeding back them. CONSTITUTION:Transistors(TRs) Q1, Q2 constitute an emitter follower type class B SEPP circuit. The error amplifier consists of TRsQ3-Q5 and Q6-Q8 and input terminals (a)-(c) and (a')-(c') are connected to the base of each TR. Constant current sources I1, I2 are set as I1>I2. The emitters of the TRs Q1, Q2 are connected respectively via a resistor RE and the connecting point is connected to an output terminal OUT via the resistor RE. The emitters of the TRs Q1, Q2 are connected to the terminals (a), (a') and an input terminal IN is connected to the terminals (c), (c') via a bias power supply. A voltage from the resistor RE extracted at the output terminal OUT is fed back to the terminals (b), (b'). Thus, the distortion at the output terminal OUT is reduced remarkably and the temperature compensation of the idle current is not required.

Title: Fixing structure for fixture of string
Inventor: SUZUKI YUKIO
IPC: H05K5/02
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To avoid producing extraordinary sounds due to vibrations, ensure a case housing space and improve the assembling work efficiency of a chain coupler for coupling a string or chain by providing a case frame so as to expose the coupler outside the case. SOLUTION: A chain coupler 29 is attached to the frame of a main case. This makes it possible to effectively utilize the housing space of the case, mount an antenna 19 at specified distance from a noise source 20, and maximize the antenna aperture area. If a small sized electronic apparatus oscillates due to operation of a vibrator, a metal 33 neither plays in a hole 38 nor produces extraordinary sound. The metal of the coupler 29 uses an L-shaped metal plate easy to handle and protrusions are formed at legs to provisionally fix during assembling. This eliminates troublesome works, resulting in improved working efficiency. Thus it is possible to avoid producing extraordinary sounds due to vibrations and improve the assembling work efficiency of the chain coupler.

Abstract: PURPOSE:To prevent pressure difference at opposite sides of a movable iron core, by defining a through hole in the movable iron core in its axial direction in such a manner that it communicates with a groove formed on an adsorption surface. CONSTITUTION:When a coil 4 is excited by turning on the power on condition that a movable iron core 7 is depressed by a coil spring 21, a second valve body 17 is apart from a second valve seat 19, and a first valve body 16 is forced to a first valve body 18 under pressure, the movable iron core 7 is adsorbed to a fixed iron core 6 against an action of the coil spring 21. Even if oil, drain or the like enters into a gap between a coil bobbin 5 and the movable iron core 7 in this condition, no pressure difference is caused because a groove 9 communicates with a first valve chamber 14 at all times by defining a through hole 8 in the movable iron core 7, whereby non-release is prevented securely.

Title: Case structure of stabilizer
Inventor: FURUSAWA HIDEYUKI
IPC: H01F37/00
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To prevent a stabilizer body from being moved owing to produced gas, by forming a gap at a proper portion between an outer surface of an opening in a case body and an inner surface of a peripheral wall of a cover for allowing the produced gas from a compound to pass therethrough. SOLUTION: A plurality of concave parts are provided around an opening 2 in a case body 3. A plurality of convex parts 13 are provided on a peripheral wall 10 of a cover 4. The number of the convex parts 13 is larger by one than that of the concave parts. For this, when the cover 4 is fitted over the case body 3, the one convex part 13 not combined with the concave parts makes contact with a flat surface 3a of the partner whereby a gap is formed in the periphery of the contact part. The gap is not adapted such that it interrupts leakage of a compound 15 filled around a stabilizer body 6 but it also interrupts the produced gas from the compound 15, and hence the produced gas is prevented from being filled.  Thus, the stabilizer body 6 is prevented from being moved owing to the gas being filled and likewise from making contact with other electric parts 7 and short-circuitting with the same.
