Title: Method for fixing noise preventing core
Inventor: NISHIO ATSUSHI
IPC: H01F17/06
Filed: 1990-11-30
Abstract: PURPOSE:To prevent a ferrite core from being deflected in position by the pressure of a resin by providing locking sections for stopping the deflection of the ferrite core in a resin forming mold and molding the resin after fixing the ferrite core by means of the locking sections. CONSTITUTION:After a ferrite core 15 is put in a mold 20 and fixed with locking section 25 for stopping the deflection of the core 15, the mold 20 is filled up with a molten resin of polypropylene, etc., and the resin is hardened. A connector 10, cable 12, and the ferrite core 15 are integrally coupled with each other and their relative movement is controlled. Since the resin is molded after the resin is injected into the mold 20 while the core 15 is locked by means of the sections 25, the deflection of the core 15 due to the pressure of the resin can be avoided and the of the core 15 is fixed, since the periphery of the core 15 is uniformly coated with the resin.

Title: Tube for pneumatic tire
Inventor: KATO YUKICHI
IPC: B60C5/04
Filed: 1993-12-03
Abstract: PURPOSE:To allow air between the tire and the tube to come out of a gap between a bulb and a bulb hole by forming a projection in almost all the circumference of the bulb hole over the outer surface of the tube where the bulb is projected out, and the bulb hole is sealed. CONSTITUTION:The tube 15 within the tire 9 is made up of a crown section 16 abutting against a tread section, a pair of a right and a left shoulder sections 17, a base section 18 and of a bulb 19. A circular projection 20 is formed in the entire circumference in the circumferential direction, the gauge of the tube 15 at the aforesaid section is thicker than that of the crown section 16 by that much equivalent to the projection 20, so that the strength of the aforesaid section is intensified because of an rib effect by the projection 20. When air is filled in the tube, the crown section 16 abuts against the tread section of the tire 9, the base section 18 is finally swelled up thereafter, so that the base section thereby abuts against a rim 3. Air between the inner surface of the tire 9 and the tube 15 is pushed out from the outer circumferential section side toward the bulb 19 side in the inner circumferential section, so that it thereby comes out of a gap between the bulb 19 and a bulb hole 7.

Title: Paper feeder
Inventor: BABA KENJI
IPC: G03G15/00
Filed: 1990-11-30
Abstract: PURPOSE:To surely prevent diagonal feeding by feeding paper based on output of a deflection sensor through driving of a feeding means and a resist roller at almost the same circumferential speed when paper is in the deflected state and through stopping of the feeding means and driving of only the resist roller when the deflection of the paper is solved. CONSTITUTION:When a rear end of paper which is being fed downstream by a resist roller 27 in the deflected state leaves a feeding means 25, the deflection is solved. When a deflection sensor 49 detects it, a controlling means stops the feeding means 25. That is, the paper is fed in the deflected state till its rear end leaves the feeding means 25. Thus, in feeding the paper downstream of the resist roller 27, the paper is fed without drawn, which eliminates dislocation of attitude of the paper.

Abstract: PURPOSE:To improve error correction capability by generating a softness decid ing value for the waveform of a signal and decoding all codes to data '1' and '0' according to an Euclid's distance between a maximum value '1' and a minimum value -1. CONSTITUTION:A detector 2 is provided to demodulate a digital modulated wave like an ML (n, 1) code to a base and band signal, and equalizer 3 is provided to execute softness decision, etc., to the demodulated base band signal.
