Title: Magnetic head, its manufacture and magnetic recorder/ reader
Inventor: FURUSAWA KATSUYOSHI
IPC: G11B5/127
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic head with extremely reduced warp on its tip facing a recording medium, a manufacturing method for the magnetic head and a magnetic recorder/reader. SOLUTION: The magnetic head is provided with a core 2 for generating magnetism and read/write information on a recording medium, a housing 1 for holding the core 2, plural supporting parts 1a, 1b, 1c and 1d formed in the housing 1, and a high ridigity adhering member 16 for fixing the supporting parts 1a to 1d to the core 2 on the opposite side of a part facing the recording medium. Since the elasticity of the fixing part of the magnetic head on the opposite side of the part facing the recording medium is extremely low, downward deflection (in a direction from the side facing to the recording medium to the opposite side) does hardly occurs at the time of polishing the surface of the magnetic head. Thereby warping of the polished surface upward by repulsion caused by the elastic power of the adhering member hardly occurs.

Title: Manufacture of laminated electronic component
Inventor: NAKAMURA TOSHIYA
IPC: H01G4/12
Filed: 1994-03-17
Abstract: PURPOSE:To obtain laminated electronic component in which an internal stress is comparatively uniform and in which no delamination is genetrated between an internal electrode and a protective layer by using a ceramic green sheet, for the protective layer, whose firing shrinkage rate is closer to the firing shrinkage rate of a conductive paste film than to the firing shrinkage rate of a ceramic green sheet. CONSTITUTION:As ceramic green sheets for protective layers, ceramic green sheets whose firing shrinkage rate is closer to the firing shrinkage rate of conductive paste films than to the firing shrinkage rate of ceramic green sheets are used. Thereby, when a laminated-body chip is fired, the ceramic green sheets for protective layers 22 are shrunk in a state which is close to the shrinkage rate of the conductive paste films for internal electrodes 21. As a result, when the ceramic green sheets for the protective layers 22 are shrunk, a large stress is not applied unevenly to the inside of a laminated electronic component, and the inside of the laminated electronic component is fired comparatively uniformly. Consequently, it is possible to obtain the laminated electronic component in which an internal stress is comparatively unifrom and in which an irregularity in an electric characteristic is small.

Title: Radio communication system
Inventor: NUMAGAMI KOICHI
IPC: H04W48/18
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To allow a radio communication system to automatically select a relay communication mode where mobile stations make communication with a relay of a base station or a direct communication mode where the mobile stations make direct communication not through the base station. SOLUTION: A base station transmits a 1st carrier signal f1 for communication with a mobile station and uses a 2nd transmission section 20 to always transmit a 2nd carrier signal f2. The mobile station always receives the 2nd carrier signal f2, a reception level detection section 37 detects a reception level of the f2, and a bit error rate detection section 39 detects a bit error rate of received data by the 1st carrier signal f1. When the detected reception level is a reference level or below, the bit error rate exceeds a reference value and the state is consecutive for a prescribed time (1st timer section 41), the mobile station selects a direct communication mode using an exclusive frequency f4 from a relay communication mode.  The base station instructs an opposite mobile station to allow the opposite mobile station to select the direct communication mode from the relay communication mode.
