Title: Liquid sealing type vibration control device
Inventor: KATO RENTARO
IPC: F16F13/20
Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To obtain excellent vibration isolating effect even in a high frequency area by disposing a gas-sealed elastic body formed of a flexible film into bag shape with gas sealed therein, inside a main liquid chamber. SOLUTION: When hydraulic pressure in a main liquid chamber 43 rises in association with the volume change of the main liquid chamber 43, a gas- sealed elastic body 7 engagedly fixed to an umbrella-shaped member 6 in the main liquid chamber 43 is elastically deformed and contracted so as to relax the rise of hydraulic pressure. At this time, even though a narrow passage 64 is put in a plugged state (a state of impeding the flow of liquid L in the narrow passage 64), the gas-sealed elastic body 7 is contracted to relax the rise of hydraulic pressure. Excellent vibration isolating effect can therefore be obtained even in a frequency area higher than a frequency area where low dynamic springiness based on liquid column resonance action of liquid L flowing in the narrow passage 64 effectively works.  In addition to vibration isolating effect in the high frequency area obtained by providing the umbrella-shaped member 6, excellent vibration isolating effect can therefore be obtained in the high frequency area higher than the above-mentioned high frequency area.

IPC: G11B7/085
Filed: 1994-11-14
Abstract: PURPOSE: To obtain an angular moment in the direction of correcting an inclination of an optical head due to fitting backlash of a bearing part when a guide mechanism with ball bearings is changed to a guide mechanism with sliding bearings by working a correcting coil to prevent this inclination. CONSTITUTION: A carriage 3 is, of course, not inclined in the state of repose, and even when a seek operation coil 4 is energized, the correcting coil 5 connected in series is simultaneously energized. Consequently, a correcting angular moment is generated clockwise by the correcting coil 5 to cancel and angular moment generated counterclockwise on the carriage side by driving force of reaction of the coil 4 generated on the carriage side caused by downward driving force by magnetic circuits. Now, the bearings 3a and 3b of the carriage 3 are both brought into contact with a guide rail in the upper parts of the bearings, the carriage 3 is never inclined, and an objective lens 2 and a mirror are never inclined either.

Title: Composite magnetic head
Inventor: HISATOMI MASUMI
IPC: G11B5/17
Filed: 1991-10-25
Abstract: PURPOSE:To reduce a ferrite noise by having a short ring being wound a conductive body around a circumference of a core in parallel to a head running direction between a sliding surface against a medium and a winding wire. CONSTITUTION:A magnetic head 1 is constituted with a ferrite 2 and a magnetic metal 3 and the winding wire 4 is wound around both cores 11. Between the sliding surface 5 and the winding wire 4, A 1 is attached as the conductive body 6 so as to wind each core 11 in parallel to the head running direction. A short ring winding around each core 11 with the conductive body 6 and the magnetic metal core 3 is formed. The magnetic flux 7 of the ferrite noise generated by sliding against the medium is orthogonally crossed with the short ring and on the other hand a signal flux 8 taken in from the medium 10 via a gap 9 flows mainly in the metal core 3, and a magnetic flux flowing in the remaining ferrite is intersected with an angle theta to the short ring. Since the effective permeability of a magnetic path of the magnetic flux 7 becomes lower than that of the short wring, the noise magnetic flux does not reach to the winding wire 4, thus the ferrite noise is reduced.

Title: Signal format for image signal, format conversion method for image signal and its device
Inventor: HORI AKIHIRO
IPC: H04N7/00
Filed: 1996-10-22
Abstract: PROBLEM TO BE SOLVED: To facilitate image processing in a computer and data compression by selecting the number of lines for a valid scanning lines to 576 and to 1024 for a valid horizontal pixel. SOLUTION: As a sequential scanning system digital component coding adopted by the PAL/SECAM systems, the 2.4:2:2p (625) system and the 4:2:0p (625) system are considered. The valid scanning line number is 576 and the valid horizontal pixel number is 720, and the aspect ratio is 16:9. In order to obtain square pixel arrangement without changing the number, 576, the number of pixels is to satisfy 16/9×576=1024. Furthermore, since image data quantity is huge when non-compression is adopted in the case of recording/transmission of image data, data compression is required. In the case of the JPEG or the MPEG, one block for DCT transformation is 8×8 pixels and color difference information adopts a sample point a half of that of luminance, then a multiple of 16 is advantageous for number of pixels.  Then 1024 is adopted for the number of horizontal valid pixels, each pixel is arranged as a square pixel form and the image processing by a computer is facilitated.

Abstract: PURPOSE:To prevent formation of fine particles in the step of treating an oxide film on a wafer with hydrofluoric acid and to improve yield of manufacturing semiconductor by providing an inert gas purging mechanism for forming an inert gas atmosphere in a chamber and a fine particle discharging mechanism for controlling a gas flow in the chamber. CONSTITUTION:N2 tubes 6, 8, valves 7, 9, exhaust ports 10, 12 and suction pumps 11, 13 are operated as an inert gas purging mechanism. For example, the valves 7, 9 are opened, and N2 is introduced from the tubes 6, 8 to form an N2 atmosphere in a chamber 1. The N2 is discharged from the ports 10, 12 by the pumps 11, 13 while introducing the N2 from the tubes 6, 8, thereby forming a down-flowing state of the N2 in the chamber. Then, a semiconductor wafer 2 is conveyed from a loader side, fixed to a stage 3, and hydrofluoric acid is injected from a chemicals injecting unit 4 while rotating the state 3, thereby removing an oxide film. In this case, an SiO2 is not almost formed. Even if a trace amount of ultrafine particles are formed, it is discharged from a lower part of the chamber due to the downflowing state.
