Title: Noise removing circuit and its method
Inventor: ENOMOTO KAZUYOSHI
IPC: H04B1/10
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of distortion of output waveform by generating reproduction noise following the phase fluctuation and amplitude fluctuation of noise from phase information and amplitude information and making the phase of this reproduction noise coincide with the phase of the noise so as to follow up the phase of the noise and the fluctuation of amplitude so as to remove noise. SOLUTION: A first BPF 2 extracts noise mixed in an input signal. A phase information extracting circuit 13 extracts phase information of the noise from the output signal of the first BPF 2. An amplitude information extracting circuit 14 extracts amplitude information of the noise from the output signal of the first BPF 2. A multiplier circuit 9 outputs a sine wave signal (reproduction noise) following up the phase fluctuation and the amplitude fluctuation of the noise mixed in the input signal from extracted phase information and amplitude information. A phase shifting circuit 10 makes the phase of the reproduction noise outputted from the circuit 9 coincide with the noise mixed in the input signal. A subtraction circuit 11 subtracts the output signal of the circuit 10 from the input signal.

Title: Control oil pressure feeding apparatus for belt type continuously variable transmission
Inventor: MORISAWA KUNIO
IPC: F16H9/18
Filed: 1984-11-20
Abstract: PURPOSE:To prevent the meandering of a transmission belt and improve durability by constituting a feeding oil passage formed in the axial direction on a rotary shaft so that the both edges are closed in the rotary shaft and forming a communication hole to a hydraulic cylinder apparatus and a taking-in hole from a hydraulic source in the radial direction onto the rotary shaft. CONSTITUTION:The control hydraulic pressure of a hydraulic cylinder apparatus 130 is supplied through a feeding oil passage 108 formed in the axial direction on a rotary shaft 104. The right edge of the feeding oil passage 108 is closed by a wall surface, and the left side is closed by a sensing valve 500. Further, taking-in hole 502 and a communication hole 506 are formed in the radial direction. Therefore, when the control hydraulic pressure passes through the feeding oil passage 108, each thrust force generated in the direction of the both edges is offset, and the generation of thrust force can be prevented.

Title: Magnetic disk device
Inventor: OGAWA YOSHIAKI
IPC: G11B20/12
Filed: 1990-09-14
Abstract: PURPOSE:To shorten time required for searching sectors and to improve the use efficiency of a medium by setting plural continuous sector pulses to be a unit, combining the presence or absence of the sector pulses and expressing the address of a sector part. CONSTITUTION:Plural pulses 13 are allocated to the sector pulse 12 becoming the reference of respective sectors in the sector part 16 as one unit and the addresses of respective sectors in the sector part 16 are expressed by the presence or absence of the pulses 13. Thus, information on ID of the sectors can be obtained without reading ID information from the medium at the time of searching the target sector, and searching time for the target sector can be shortened. Since the sector pulse itself includes information on the sector, the use efficiency of the medium can be improved without damaging the reliability of access at the time of accessing to respective sectors.

Title: Semiconductor board, its manufacture and its use method
Inventor: KIMURA YASUHIRO
IPC: H01L21/02
Filed: 1995-09-25
Abstract: PURPOSE: To avoid lowering of mechanical strength, reduction of an effective use area and irregularities of a resist film, etc., by forming a detection sign for detecting crystal orientation of a semiconductor wafer in a specified region of a semiconductor wafer whose outer circumferential part is a circle all over. CONSTITUTION: An impurity region 2 for detecting crystal orientation of a silicon wafer 1 is formed in an outer circumferential part of the silicon wafer 1 in a semiconductor substrate. An absorption amount of infrared ray 9 passing through the silicon wafer 1 is measured by a combination of an infrared ray generation device 8a and an infrared ray detector 8b. In the impurity region 2, an absorption amount of infrared ray is large as compared with a part except the region since there is infrared ray absorption due to containing impurities. Therefore, a position of the impurity region 2 is detected by detecting a point wherein the infrared ray absorption amount becomes large. Crystal orientation of the silicon wafer 1 can be readily specified in this way.

Title: Method for manufacturing multilayer-printed wiring board
Inventor: SATO NORIYUKI
IPC: H05K3/46
Filed: 1994-09-14
Abstract: PURPOSE: To prevent the crease on the surface of a multilayer copper-clad lamination board by striking an eyelet into a reference hole for aligning position between an inner-layer plate and the specific position of a first prepreg, dividing the tip of the eyelet into 3 to 10 portions, caulking the first prepreg, and further caulking them again with a pivot block for caulking. CONSTITUTION: In a second caulking process after a first caulking process, re-caulking is further performed with a caulking tool for second caulking process. An eyelet 3 whose tip is divided is spread in horizontal direction and the height is lowered to some extend, thus eliminating the elevation difference between the eyelet 3 and the inner-layer plate 1. By performing caulking again, stress near the eyelet cannot be dispersed and appears as crease on the surface of the copper foil 4 since the conventional eyelet is heated as it is high and is formed as a multilayer plate in one piece. By eliminating the elevation difference between the eyelet 3 and the inner-layer plate 1 again, the crease on the surface of the copper foil 4 can be prevented.
