Title: Multi-arc bearing
Inventor: IDA DOUSHIYUU
IPC: F16C17/02
Filed: 1980-04-09
Abstract: PURPOSE: To restrict a resonant phenomenon to occur in a rotary shaft system by tilting the multi-arc journal bearings supporting the rotary shaft in the circumferential direction with respect to a bearing housing so that the kinetic characteristics of bearing oil film can be varied.  
     CONSTITUTION: The journal bearing 3 comprising an upper bearing member 3a and a lower bearing member 3b is provided within the bearing housing 2 tiltably, while the bearing surface 3 is formed in oval shape. A bevel gear 4 is provided on the circumference of the bearing 3 and said bevel gear is made to mesh with a bevel gear 5 which is rotatably supported by the housing 2. When the bevel gear 5 is rotated by the loosening of a fixing nut 6, the bearing 3 is tilted by the bevel gear 4 within the bearing housing 2, thereby varying the bearing oil film kinetic characteristic of the bearing 3 with respect to the rotary shaft 1. Thus, the natural oscillation of the rotary shaft 1 can be separated from the frequency of an oscillation source to restict effectively the resonant phenomenon of the rotary shaft 1.

Title: Manufacture of semiconductor device
Inventor: MATSUE KENJI
IPC: H01L21/3205
Filed: 1987-02-27
Abstract: PURPOSE:To prevent the breakdown of a wiring at a contact region, by forming metal on a contact region, thereafter forming an interlayer insulating film, applying positive type resist thereon, exposing and developing the entire surface, forming a hole in the positive resist on the contact region, and thereafter performing etching. CONSTITUTION:A positive type resist film 17 is applied on a part, where an interlayer insulating film 16 is formed. The thickness of the positive type resist film becomes thin at a part, where a step part is steep, or at a region, where the step part is high. When the entire surface of a wafer is exposed under this state, the thin positive type resist film on the region, where metal is formed, is exposed to light, which is reflected from the surface of the metal, and the light from the upper side. Therefore, the amount of the absorbed light becomes much in comparison with the resist film in the other region. When development is performed, the positive type resist film on the region, where the metal is formed, is developed in a developing time shorter than the time for the positive type resist in the other region. Then, the interlayer insulating film on the metal is etched, and the surface of the metal is exposed. The positive type resist film is removed, and a lower metallic wiring layer 18, which is to become a wiring, is formed. Thus a contact region and the metallic layer 18, which is to become the wiring, are connected.

Abstract: PROBLEM TO BE SOLVED: To provide an image recorder capable of always obtaining accurate calibration result by informing of calibration accuracy. SOLUTION: A density difference between the measured density value of each patch of a test chart image recorded on photosensitive material by an automatic calibrator and the target density of each patch based on test chart image data is calculated. Based on the calculated density difference in each patch, the accuracy (per cent value) of the correction of printer LUT(lookup table) is obtained according to decision reference stored in a ROM. The accuracy of the correction is compared with previously set target accuracy so as to decide the propriety of the calibration. When the accuracy of the correction is within the target accuracy, a message showing that the result of the correction is good is displayed on the display of an image processing part and calibration processing is finished.  When the accuracy of the correction gets out of the target accuracy, a message showing the result of the correction is not good is displayed on the display of the image processing part.

IPC: G10L21/0264
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce a voice amplitude spectral component to be erroneously withdrawn with an estimation error component by making a frame length to be the length of the natural number times of the basic cycle of the voice signal in an input signal in a spectral subtraction method and performing the orthogonal transformation and the inverse orthogonal transformation of the frame length. SOLUTION: The basic cycle of an input signal in which noise is superposed on a voice is calculated and the bacic cycle is increased by a natural number times to be made to be a frame length M (SP1). The frequency spectrum of the input signal is calculated by performing discrete Fourier transforms of M points of the frame signal having this frame length (SP2). When the number of points N of estimation noise amplitude spectrums is different from the calculated frequency spectrums M, the number of points of the estimation noise spectrums is transformed into M (SP3). Then, the frequency spectrum of the voice is calculated with the processing of the spectral subtraction from the frequency spectrum of the input signal and estimation noise amplitude spectrums (SP4) and an output signal is obtained by performing inverse discrete Fourier transforms of M points of the frame length (SP5).
