Title: Formation of thin film
Inventor: ITOU TAKASHI
IPC: C23C14/24
Filed: 1980-11-07
Abstract: PURPOSE:To effectively avoid the occurrence of a cutting incident of a formed thin film, etc. by linking an evaporation chamber and a vapor deposition chamber together through a small opening and making the vaccum degree of the former chamber higher than that of the latter chamber. CONSTITUTION:An evaporation chamber 11 and a vapor deposition chamber 12 are separated from each other, and they are linked together through an opening 12b made in a partition wall 12a. The chamber 11 is evacuated to about 10<-5> Torr vacuum degree, and the chamber 12 to about 10<-2> Torr vacuum degree. After regulating the internal pressures of the chambers 11, 12, a substance 13 for vapor deposition in the chamber 11 is evaporated by an ordinary method. The evaporated particles enter the chamber 12 through the opening 12b, hit on the atmospheric gas in the chamber 12, and deposit on a substrate 14 from many directions. Thus, a vapor deposited film having a uniform thickness is formed even if the surface of the substrate 14 is uneven. By this method the breaking of Al wiring, etc. can be prevented perfectly.

Title: Automatic playing device
Inventor: KOZUKI KOICHI
IPC: G11B31/02
Filed: 1987-06-25
Abstract: PURPOSE: To make it possible to instantaneously confirm recorded performance without executing reproducing operation after recording the performance by automatically turning the mode of the automatic playing device to a reproducing mode after the end of recording of the performance in the recording mode.  
     CONSTITUTION: When performance is to be reproduced after ending its recording, switching operation for setting up the device to a reproducing mode is normally required. When a start/stop switch (S/S switch) 40 is depressed instead of the switching operation after ending the recording of performance executed by the recording mode of the device, recording mode sequencer is automatically switched to a playing state. Thereby the device is automatically turned to the reproducing mode simultaneously with the end of recording of the performance and the performance can be instantaneously confirmed. Even when plural playing parts exist, these playing parts are simultaneously turned to the reproducing mode and their performance can be listened.

Title: Magnetic head
Inventor: KUREBAYASHI MASAAKI
IPC: G11B5/127
Filed: 1988-06-27
Abstract: PURPOSE:To improve the mounting accuracy and the efficiency of mounting work of a magnetic head by providing a marker for detecting a gap position at a position keeping prescribed constant relation with an operating gap. CONSTITUTION:The marker 5 for detecting the position easy to discriminate is formed at the position keeping the constant relation with the operating gap 3. The marker for detecting the gap position is provided on one side or both sides of the operating gap, and since its width receives no regulation by a track pitch, etc., it can be formed larger than track width. Also, thickness can be formed thicker than the gap length of the operating gap similarly. There fore, the marker can be discriminated easily even that it is constituted in the same shape as the operating gap. In such a way, since it is possible to accurate ly and easily decide the gap position by the gap position marker even when it is hard to decide the position of the operating gap on a sliding plane, the mounting of the magnetic head can be performed with high accuracy and effi ciently.

Title: Noise reducing circuit for high picture quality video signal
Inventor: YUU HITSUKOU
IPC: H04N19/59
Filed: 1991-06-27
Abstract: PURPOSE: To generate a high picture quality video signal by dividing a high frequency component into a fixed number of two-dimensional blocks, generating an adaptive counting by the maximum value in each block, multiplying it by each pixel, channel- transmitting the multiplied value, dividing the received signal by this adaptive counting again and reducing a channel noise mixed under transmitting to the degree of that counting rate. CONSTITUTION: The video signal is supplied to an absolute value 100 and a delay compensating circuit 500 from an input terminal 101, and the supplied signal is divided into 4×4 pixels of blocks in a horizontal and vertical two-dimensional structure. The maximum value is detected from that pixel data by a maximum value detecting circuit 200. Then, a block adaptive coefficient is calculated by a block adaptive counting generating circuit 300, and a pixel adaptive counting generating circuit 400 generates a pixel adaptive coefficient by interpolation. Here, the delayed-compensated (500) pixel is multiplied (600) by the pixel adaptive coefficient, and the multiplied value is transmitted.  On the other hand, in a decoder 2000, the pixel adaptive coefficient is generated again using a pixel adaptive counting circuit 800, and a dividing (900) is performed on the generated coefficient to restore an original pixel value.
