Title: Cooling device and optical information recording and reproducing device having the same
Inventor: WATANABE MASAHIKO
IPC: G11B33/14
Filed: 1990-01-24
Abstract: PURPOSE:To eliminate dust attached on a filter and to recover a cooling effect by reversing the direction of a fan with the filter as necessary. CONSTITUTION:During the ordinary action time of a device, outside air is exhausted to the outside by the fan through a passage shown by an arrow and it cools the main unit of a magneto-optical disk. When the device is used for a long time, the filter 1 is clogged, air quantity is reduced and the temperature of the main unit of the disk is raised. Then, the fan 3 is rotated in a reverse direction in a prescribed time after a fixed time when a power source is turned on. Besides, an AC signal is added to the piezoelectric element of an exciter 2. Then, the dust attached on the outside of the filter 1 is eliminated.

Title: Magnetic head slider and magnetic head slider supporting mechanism
Inventor: HIGASHIYA TERUYOSHI
IPC: G11B21/21
Filed: 1995-01-31
Abstract: PURPOSE: To provide a contact recording magnetic head slider capable of reducing vibrations caused by contact with a rotary magnetic disk. CONSTITUTION: By providing a projecting section 21 in contact with the inner peripheral side of a magnetic disk and a projecting section 22 in contact with its outer peripheral side and setting the contact area of the inner peripheral side projecting section 22 with the magnetic disk larger than that of the outer peripheral side projecting section 21, shearing forces with the magnetic disk applied to both projecting sections 21 and 22 due to a difference in circumferential speeds are balanced and vibrations are reduced. The shearing forces are also balanced by adjusting the distance from a pivot for instructing a magnetic head slider to the projecting section and surface roughness on the projecting section. Thus, the movement of the magnetic head slider is made stable and a high density recording/reproducing of data is attained.

Title: Method and apparatus for automatic matching of image pattern
Inventor: SAKAMOTO TAKU
IPC: G03F1/92
Filed: 1979-02-14
Abstract: PURPOSE: To automatically match image patterns readily and surely by optically detecting the register marks provided in the opposing positions of the superposed original plate films thereby controlling the relative positions of the original plate films.  
     CONSTITUTION: When the register mark 24 of an original plate film 1a opposes to a photoelectric converting means 21, the quantity of received light of the means 21 is decreased by the decrease in the photo detecting area. When the film 1a is moved to the position corresponding to the intermediate part during the time until this quantity of received light again increases after the decrease, then the mark 24 matches the means 21. Thence, the second original plate film 1a' is superposed on the film 1a and when the mark 24' provided in the position opposing to the mark 24 is detected with the means 21, the marks 24, 24' superpose in the central part within the region where the quantity of received light of the means 21 further decreases according to the relative position of the marks 24, 24'. When the films 1a, 1a' match, the quantity of received light of the means 21 increases.

Title: Optical circuit element
Inventor: MATSUI TERUJI
IPC: G02B6/34
Filed: 1979-02-13
Abstract: PURPOSE:To provide a compact and accurate light branching filter in an optical fiber communication system, by arranging a polarizer, a phase difference plate of optical anisotropy and a double refractive crystal plate in series with one another. CONSTITUTION:A thickness of crystal of optical anisotropy is selected to meet prescribed conditions to make a phase difference plate 9. Light having wavelengths lambda1, lambda2 is removed of only equal polarized light components by a polarizer 8. Other light components of lambda1, lambda2 in wavelength are then picked out by the wavelength dependence of the refractive index of the plate 9 in such a manner that the oscillation planes of the components perpendicularly intersect each other. The optical axis 11 of a double refractive crystal plate 10 is placed on the same plane as one of the perpendicular oscillation planes so that the incident light is divided into two light beams depending on the directions of oscillation. One light beam proceeds straight but the other proceeds obliquely. As a result, the light having the wavelengths lambda1, lambda2 is divided into the two parallel light beams.

IPC: H01L21/76
Filed: 1993-02-02
Abstract: PURPOSE:To satisfactorily isolate between element formation regions and to satisfactorily operate elements formed in the individual element formation regions by a method wherein a high-concentration inversion-preventing layer which has been doped with impurities at high concentration is formed in a region in which the isolation breakdown strength may be degraded. CONSTITUTION:A high-concentration inversion-preventing layer 32 which contains impurities at high concentration is formed in a region S1 between one pair of contact holes 28 in which there is a fear of the degradation of an isolation breakdown strength. As a result, even when the formation position of the contact holes 28 is dislocated, the isolation breakdown strength between element formation regions 41, 42 is not lowered. In addition, since the high-concentration inversion-preventing layer 32 does not reach the formation region of a gate electrode, a narrow channel effect is not caused. In addition, the concentration of an inversion-preventing layer at the lower part of a field oxide film 2 is not increased in the whole region of a silicon substrate 21, but the high-concentration inversion-preventing layer 32 is formed only locally in a required region. As a result, the contact area of the high-concentration inversion- preventing layer with N<+> type impurity-diffused layers 26, 30 can be suppressed to be small.

Abstract: PROBLEM TO BE SOLVED: To always stably record halftone dot gradation images based on printing data by generating, from video input signals, output signals for only dots of a halftone dot image pattern corresponding to a halftone dot set preliminarily recorded among halftone dot sets having a plurality of different halftone dot characteristics. SOLUTION: An image pattern-detecting part 219 of a pixel substitute circuit 209 stores a part of halftone dot sets used in a printer engine 210 as a detect image pattern 221 therein, detects a part of the halftone dot set from an input video signal 213 and generates a corresponding detect image pattern signal 221. Therefore, a halftone dot image area can be detected and corrected from the already binarized signal 213. In the case where recording is to be carried out with the halftone dot set of different halftone dot characteristics when a characteristic of the engine 210 changes, a printer controller 202 downloads the halftone dot set of different halftone dot characteristics to the circuit 209 before the printing is carried out, and changes the pattern 221.
