Patent JP-S56157133-A (JP)
Title: Receiver
Inventor: NISHINO KAZUYUKI
IPC: H04B1/18
Filed: 1980-05-07
Abstract: PURPOSE:To secure a dynamic range and reduce a distortion, a cross modulation and a mutual modulation disturbance, by forming both an attenuating means and an amplifying means in a body with an antenna element. CONSTITUTION:When a command switch SW1 of the receiver main body 1 is applied, the output A of a comparator 40 is set at a high level. Thus an antenna induced signal receives an attenuation since the variable impedance circuits 38 and 39 are activated to have a low impedance, respectively. When the SW1 is opened, the output A of comparator 40 is turned to a low level. And the impedances of the circuits 38 and 39 become infinite, and thus the antenna induced signal receives no attenuation. Accordingly the switch SW1 is applied in such case the field intensity increases to start saturation of a circuit. As a result, the signal is attenuated to suppress the saturating action. The switch SW1 is opened in the medium/weak field to ensure a reception with a high sensitivity.

Title: Disc-shaped molded material
Inventor: GOMI TAKEO
IPC: F16F15/305
Filed: 1986-03-18
Abstract: PURPOSE:To obtain a high speed rotating disc-shaped molded material of good rotary performance, by suitably laminating a layer, in which one-directionally oriented carbon fiber preimpregnation is artificially isotropically laminated, and a circumferentially wound material. CONSTITUTION:A mold, consisting of a pair of upper and lower molds, is prepared, and a one-directional material or a circumferentially wound material, which is mounted onto the lower mold 3, performs preliminary pressurization by the upper mold 1. Here an effect of the pressurization is obtained if the metal mold is preheated to a low temperature for sufficiently fitting a molded material, while the method, in which a mold releasing sheet 4 is interposed preventing the molded material 2 from adhering, is also applied. And after the molded material 2 is fitted to the metal mold, preliminary molding is performed by similarly charging the mold with the second material and laminating it successively in the determined lamination order. Further these materials, when their shape is not so complicated, can be also pressurized simultaneously by charging the mold with these materials at one time. After the above molding, the high speed rotating disc-shaped molded material can be obtained by applying the temperature and the pressure necessary for molding a carbon fiber compound material as performed in the past.

Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To increase anchoring strength to a reinforcement and concrete by using a diametrically expanded part formed by applying hot upsetting treatment to the reinforcement as an anchoring part. SOLUTION: In an anchoring part reinforcement 1A, a disk-shaped diametrically expanded part 1b is respectively formed in a reinforcement part having a constant diameter, that is, both side end parts of an ordinary part 1a as the anchoring part by hot upsetting treatment. Since this diametrically expanded part 1b can secure the large action area even if an outside dimension is reduced more than an ordinary anchoring part by bending a reinforcement end part in a U shape or an L shape, anchoring strength to the other reinforcement and concrete can be increased. Moreover, since the diametrically expanded part 1b is completely made as an integral structure in the ordinary part 1a, connecting strength of the diametrically expanded part 1b and the ordinary part 1b increases, so that the strength is stable.  To increase strength and anchoring strength of a connecting part, there are cases where a reinforcing part for enlarging an outside diameter more than the ordinary part of a reinforcement is arranged in a root part of the reinforcement connected to the diametrically expanded part 1b and a locking projection is arranged in a peripheral part of a surface crossing the reinforcement axis of the diametrically expanded part 1b.
