Inventor: HIRANO YASUO
IPC: C22F1/00
Filed: 1988-12-22
Abstract: PURPOSE:To produce low-zinc-content brass having good bendability by controlling the working rate of cold rolling in a copper alloy having specific compsn. and its grains at the time of annealing. CONSTITUTION:A copper alloy material contg., by weight, 1.5 to <25% Zn and the balance Cu with inevitable impurities is cold-rolled at >=35% working rate. After that, the material is annealed so that the average grains are regulated to 10 to 35mum as well as the ratio of the maximum grains to the minimum grains is regulated to <=2. The material is furthermore cold-rolled at >=35% working rate and is thereafter annealed so that the average are regulated to 2 to <10mum. After that, the material is cold-rolled and is thereafter suitably subjected to strain relieving annealing. As the result, low-brass having excellent bendability is produced, which is suitable for the production of the alloy having high strength and excellent bendability and corresponding to the need for the miniaturization of electrical and electronic parts.

Title: Molding method for contact for connector and contact for connector
Inventor: NAKAJIMA TAIJI
IPC: H01R43/16
Filed: 1993-12-21
Abstract: PURPOSE:To enable a contact having a flat contact surface to be formed by continuous press working without requiring secondary machining by performing a main-contact- surface forming process by way of a two-splitting shaving operation. CONSTITUTION:A plate 13 supporting the upper side of a long-sized plate workpiece W locates between an upper mold (movable mold) 11 and a lower mold (fixed mold) 12. The plate W is fed in the direction of its extension by predetermined pitches, and the molds 11 and 12 have a plurality of molds for every pitch of the feed of the plate W. When the plate W comes out of the space between the molds 11, 12, a series of operations is finished. In this case, the first process cuts the plate W including a temporary contact surface, and the temporary contact surface is shaved from its front and back sides by a two-splitting shaving operation in which the plate W is split into two along its thickness and machined, so as to form a main contact surface. The main contact surface can thus be made very smooth and both edges of the main contact surface along the thickness of the plate are shaped as desired, so that even if the contact is tilted a sufficient contact area and sufficient contact pressure can be secured.

Abstract: PURPOSE: To obtain a vibration control moment at least in the same extent as in a conventional structure by using a small scale gyro-stabilizer as a vibration control device. CONSTITUTION: The movement of a structure at the moment of vibration is detected by a sensor 40 and a vibration control moment necessary for the structure is calculated by a controller 30 on the basis of the detected values of the sensors 40.

A resonance current flows in an X direction and the P-axis showing the resonance mode comes to be the P-axis by shifting a feeding point 11 from a center in the X direction. Subsequently, an electromagnetic field can be obtained by assuming a magnetic current to exist in the edge side (l) of the patch 10. The parasitic elements 20 and 21 are vertically raised adjacently to the patch 10 on the P-axis. On the other hand, the horizontal parasitic elements 22 and 23 are installed detached from the substrate 1 on the Q-axis. The lengths of the elements are respectively set to be slightly shorter than lambda/4 and lambda/2. Thus, the directivity of an angle thetawith respect to the radiation main axis improves.

Patent JP-H02168862-A (JP)
Title: Switching power supply circuit
Inventor: HOTTA CHIHARU
IPC: H02M3/338
Filed: 1988-12-22
Abstract: PURPOSE:To stop the working of a switching transistor perfectly when the tertiary winding of the switching transistor is short-circuited, by connecting a capacitor to a start resistor at the ON-time of a power source, in series, to make current flow to the start resistor only at the ON-time of the power source. CONSTITUTION:When a power source is turned ON, then voltage on a 130V line rises. When the 130 line rises completely, then only DC component is left on the 130V line, and due to a DC cut capacitor 8, current does not flow to a start resistor 3 at all. Accordingly, when the tertiary winding L3 of a switching transformer 2 is short-circuited, then a self-oscillation circuit is not to be worked, and the base current of a switching transistor 1 is not fed from any place, and so the oscillation of the switching transistor 1 is perfectly stopped.

Title: Actuator device for optical pickup
Inventor: MIYOSHI KOJI
IPC: G11B7/09
Filed: 1994-12-27
Abstract: PURPOSE: To increase the tracking drive force without improving a yoke. CONSTITUTION: Parts positioned on the outer side of a tracking coil 8 of a magnet 3 are made opposite in polarity to a middle part. Consequently, the inclination of lines of magnetic force at a magnetic end part to direction Y is reduced. Then, since the number of lines of magnetic force in direction X is increased, the number of leakage lines of magnetic force in direction Z is reduced, so that tracking thrust is increased. Moreover, since no yoke 10 exists in the direction X to be hindrance, a driving amt. and a holder shape are free from control. Consequently, the small-sized and high performance actuator can thus be provided.
