Title: Lead frame and its manufacture
Inventor: OTAKI HIROKO
IPC: C25D5/08
Filed: 1993-11-04
Abstract: PURPOSE:To reduce the section of the base material of a lead frame being exposed when having cut off an outer lead and a frame and reduce the unwet section of solder too by providing a cut at the head of the outer lead. CONSTITUTION:The cutoff section from a frame 6, which is to be cut after sealing with resin, is processed as shown by the cut 4 by half etching, and besides the width of each lead at right and left side faces is made narrow. The lead frame is cut from the frame section after sealing with resin, and it is mounted and soldered on a printed wiring board where cream solder or the like is printed in advance at a terminal part. Plating is applied to the cut section too, thus the section of the lead frame base material, which is exposed when having cut off the outer lead and the frame from each other, decreases, and accompanying it, the unwet section of solder can also be reduced.

Title: Magnetic separator
Inventor: YAMAURA TAKESHI
IPC: B03C1/06
Filed: 1991-10-23
Abstract: PURPOSE:To provide a magnetic separator where the weight of a magnetic disk is lighter than that of the conventional one without lowering adsorption efficiency of magnetic particles. CONSTITUTION:A plurality of permanent magnet fragments 30a, 30a arranged in the peripheral part of a magnetic disk 20 are arranged so that the polarity of the permanent magnet fragments opposite to each other through the void 34, 34... between magnetic disks 20, 20 may be the same. Thereby the peripheral parts of the adjacent magnetic disks 20, 20 repel each other by the magnetic field of the same polarity, causing the magnetic disk 20 to be not bent. Therefore since the rigidity of a magnetic plate 28 of the magnetic disk 20 is lower than that of the conventional one, the weight of the magnetic disk 20 is lighter than that of the conventional one without lowering adsorption efficiency.

Title: Base station device and radio communication method
Inventor: HOSHINO MASAYUKI
IPC: H04B7/10
Filed: 1999-09-29
Abstract: PROBLEM TO BE SOLVED: To generate directivity at the time of transmission using a linear array antenna and to lighten the load on a transmitting amplifier. SOLUTION: When user-multiplex directional transmission is performed by CDMA communication, a phase offset for adaptively setting antenna balance is determined. Consequently, antenna elements giving maximum or minimum amplitudes are securely dispersed to each of users. Consequently, the partiality of amplitudes to a specific antenna element can be relaxed and the load on the transmitting amplifier is reduced further.
