Title: Production of fiber-reinforced metallic composite material
Inventor: KITAMURA ATSUSHI
IPC: C22C47/08
Filed: 1983-07-29
Abstract: PURPOSE:To enable easy production of a long-sized material as well with a high- pressure casting method of a fiber-reinforced metallic composite material by impregnating and compounding a metal with a reinforcing fiber aggregate in a high- pressure casting device while drawing said aggregate. CONSTITUTION:A vertically long mold 1 having the pressurizing part in the part where a plunger 3 is installed, a cavity 7 and a drawing part of a nozzle 4 is used and the cavity 7 is heated with a heating device 2 at approximately the center of said mold. A continuous fiber bundle 6 of reinforcing fibers is first inserted into the pressurizing part of the mold 1, the cavity 7 and the drawing part. A molten metal 8 which is a matrix is then poured into the cavity 7 and thereafter the molten metal 8 is pressurized with the plunger 3 to impregnate the metal 8 in the bundle 6, thereby compounding the metal and the fiber bundle. Since only the cavity 7 of the mold 1 is heated, the metal solidifies in the pressurizing part and the drawing part and acts as a seal, thereby obviating leakage of the molten metal 8. The bundle 6 in the drawing part where the molten metal solidifies and the compounding is completed is drawn by drawing rolls 5, by which the long-sized composite body is obtd.

Title: Image reader
Inventor: ONISHI TAKASHI
IPC: G03G15/04
Filed: 1988-06-03
Abstract: PURPOSE:To rationally evade a collision between an optical system and a sensor supporting arm by rocking the sensor supporting arm between a position below an original platen glass and a position retreating the glass and providing the rocking center of the arm on the side of a reference end for collating originals. CONSTITUTION:The sensor supporting arm can rock between original discriminating sensors 46-49, the position below the original platen glass 16 and the position retreating said glass 16, and the rocking center is provided on the side of the reference end A for collating originals and at the position retreating the glass 16. The title reader is provided with the sensor supporting arm 40 longitudinally provided with at least one sensor among the sensors 46-49, and a rocking and driving means rocking the arm 40 between the position below the original platen glass 16 and the position retreating therefrom. Since the sensor supporting arm 40 has its rocking center on the side of the reference end A, the optical system rocks the sensor supporting arm 40 in the retreating direction while moving even if the sensor supporting arm 40 develops retreat error, etc., therefore their collision which may damage them can be evaded.

IPC: H05K1/03
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To permit a designer to control high frequency current flowing into a power source layer through a de-coupling capacitor with the operation of IC/LSI. SOLUTION: A trunk wiring 1 suppressing DC voltage drop and distribution DC to the whole printed board with a copper foil pattern and branch wirings 2 improving high frequency impedance for separating mounted circuits 3 considered to be independent in terms of high frequency are formed on the power source layer 7.

Insulating materials on the upper/lower sides of the power source layer are formed by magnetic bodies. Thus, the distribution inductance of the power source layer is secured and the line impedance of the power source layer can be improved compared with that of the power source layer on a conventional whole plane. Then, AC voltage fluctuatoin with the switching operation of IC/LSI can be reduced with the de-coupling capacitor 4.

Title: Communication equipment, communication system and channel propriety decision method
Inventor: FUKUI NORIYUKI
IPC: H04W36/08
Filed: 1995-06-05
Abstract: PURPOSE: To prevent deterioration of the communication quality due to the channel quality deteriorated in a communication mode of a mobile communication system by estimating the channel quality to be deteriorated with age based on the evaluation result of a quality evaluation means and deciding the using propriety of a channel based on the estimated result of channel deterioration. CONSTITUTION: A waiting mobile station 24 receives a desired wave and an interference wave, and a desired wave level measurement par 11 and an interference wave level measurement part 12 measure the power levels of both desired and interference waves respectively. A division part 3 calculates a desired/interference wave ratio and stores it, and a tilt calculation part 7 calculates an increase rate of the desired/interference wave ratio for the interference wave and stores it. Receiving a call request, the mobile station 24 selects an optimum channel via a channel selection part 6 based on the desired/interference wave ratio. Receiving this selection result, a transmitter part 7 sends a selected channel designation signal to a base station 1a. The station 1a also confirms the designated channel and sends a channel rerequest signal to the station 24 if the channel is not available.  If the designated channel is available, the station 1a sends a channel response signal to the station 24. Thus the communication is started between both stations 14 and 1a.
