Title: Selective working method for metal layer composed of or containing cr applied onto semiconductor surface
Inventor: SHINODA YUKINOBU
IPC: H01L21/316
Filed: 1977-09-16
Abstract: PURPOSE: To obtain a fine pattern in a short time by attaining electrolytic etching after providing a coating such as a resist which resists against an electrolyte used for the anodization of a semiconductor surface.  
     CONSTITUTION: Ethylene glycol or propylene glycol is mixed with a tartaric-acid solution of 3% to a volume rate of 1:2 to 4, thereby obtaining electrolyte 2. Next, proper container 1 is filled with this electrolyte 2. Next, proper container 1 is filled with this electrolyte 2 and cathode 4 of platinum or gold with external connecting lead 3 and sample 6 with external connecting lead 5 are both dipped, while being confronted each other, in the solution. This sample 6 is obtained by providing a photo resist pattern onto a lamination metal film of Cr and Au adhered into the fixed region of a P type GaAs substrate surface. In this constitution, electrolytic etching at the density of 100 to 500mA/cm 2  causes the anodization of the substrate and the exposed part of the metal film disappears perfectly.

Title: Closed type electrically driven compressor
Inventor: MORI YUJI
IPC: F04B39/12
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To enhance a compression efficiency by reducing a clearance between a piston and a bore by reducing the strain of the bore occurring when a valve and a cylinder head are directly mounted to a cylinder by bolt fastening. SOLUTION: When a cylinder 1 is to be assembled with a block 14, since a flange 17 is held between a rib 19 and a cylinder head 8 together with the other parts so as to be fixed, there exists no need for directly fastening each head bolt 9 with the cylinder 1, so that the strain of a bore 2 caused when the head bolt 9 is fastened with the cylinder 1 can be reduced. Therefore, even if a clearance between a piston 10 and the bore 2 is reduced in order to prevent gas from leaking at the time of compression, friction caused by metallic contact between the piston 10 and the bore 2 can be reduced, so that a compression efficiency can be increased.

Filed: 1991-05-17
Abstract: PURPOSE:To provide an image forming device which outputs the image of stable quality by executing exposure with a light beam having a stable light quantity out of the light beams emitted from a light source. CONSTITUTION:When a light quantity sensor 52 is turned off, a shutter 50 is closed by a spring 53 so as to shield the light toward a photosensitive pressure sensitive sheet 11. When the light quantity attains a specified value, the sensor 52 is turned on, a current is applied to an electromagnetic solenoid 51, which moves the shutter 50 in a direction shown by an arrow B against the spring 53, so that the light toward the sheet 11 is allowed to pass and the sheet 11 is exposed with the light. At the same time, the current is also applied to a timer 54, which measures the current applied time. When the timer 54 measures a fixed time, the current is not applied so as not to energize the solenoid 51, then the shutter 50 moves in a direction shown by an arrow A by the spring 53 to be closed, thereby shielding the light toward the sheet 11.

Title: Floating type magnetic head
Inventor: YAMAGUCHI SHOJI
IPC: G11B5/60
Filed: 1987-05-08
Abstract: PURPOSE:To reduce friction between a magnetic recording medium and a magnetic head and to prevent the occurrence of crash between them by allowing the floating surface of a slider opposing to the recording medium to be made a curved surface wherein the sectional shape of the floating surface being perpendicular to the running direction of this recording medium is convex to the recording medium. CONSTITUTION:The floating surface 3a of the slider 3 is made to be the curved surface convexly to the direction of the recording medium 4. Therefore the floating surface 3a of the magnetic head and the surface of the magnetic recording medium at the starting time and the stopping time are line-contacted and the contacting area between them is reduced. Thus the friction occurring between the magnetic head and the magnetic recording medium 4 is reduced. Besides, as the interval between both edge face of the floating surface 3a of the slider 3 and the magnetic recording medium 4 becomes wide and foreign matters which intervenes between them is easily to run away, the occurrence rate of the crash is also reduced. As the result, the stable running in the floating can be obtained.
