Title: High-speed semiconductor device
Inventor: SUZUKI TOMIHIRO
IPC: H01L27/088
Filed: 1983-07-19
Abstract: PURPOSE:To obtain a master-slave JKFF circuit which is operated stably at a high speed with a single-phase clock by constituting a gate circuit in two levels. CONSTITUTION:The BFL system used desirably in a normally turned-on GaAs integrated circuit is adopted as a gate circuit system, and positive potential is given to VDD1-VDD8 and negative potential is given to VSS1-VSS4 at an operation time. Since the gate circuit is constituted in two levels in this circuit system, the number of gates to be inverted at the operation time is smaller than that in an all NOR constitution circuit, and consequently, the operation is performed at a high speed. Further, the circuit can be operated with the single- phase clock.

Title: Surface treatment device
Inventor: OKAMURA MASAO
IPC: C25D17/00
Filed: 1986-06-09
Abstract: PURPOSE:To maintain the specified flow rate of a treating liquid and to permit the quick discharge of deposited metals, fine dust, etc., by providing introducing ports in the extreme proximity to the aperture of a treatment vessel, allowing the treating liquid to overflow from the aperture and further discharging the same from a bottom plate part. CONSTITUTION:The surface treating liquid 2 introduced from the introducing ports 1 is discharged little by little from small holes of the bottom plate 3. The surface treating liquid 2 is recovered by an overflow part 5 when the amt. of the liquid to be introduced exceeds the amt. of the liquid to be discharged and the liquid level rises to arrive at the aperture 6. The treating liquid 2 flows in the ways shown by liquid flow 9 in this stage. As a result, the surface treating liquid 2 forms the regular descending flow having substantially no differences in the flow rates from the position slightly below the introducing ports 1 down to the bottom plate 3. Works 7 hooked to a jig 8 are thrown in this state from the aperture 6 and are immersed into the liquid down to the extreme proximity to the bottom plate 3 in the above-mentioned working state, by which the surface treatment is executed. The fine dust, fur, etc., are discharged by the overflow and the deposited metals, etc., are discharged from the bottom plate 3 by the descending flow.

Title: Semiconductor wafer
Inventor: SUGITA MASAO
IPC: H01L21/02
Filed: 1985-06-18
Abstract: PURPOSE:To eradicate a trouble due to grasping failure by describing the orientation of a surface with a laser mark without providing a notched OF surface, keeping a wafer in a circular shape. CONSTITUTION:A dotted line 10 etched with a laser is made at the same position in place of an OF surface. The width of the mark line 10 is wide, the depth is sufficiently deep and the shape is so made that the shape is not erased even if the surface is processed by a wafer process. Then, the circular shape of a wafer is maintained as it is and a trouble of grasping failure at the time of handling in an automatic process is avoided. In the case of setting the surface orientation on the base line of the stage of an exposure equipment in a photo process, the position and the direction of the laser mark line 10 are read from the change of the waveform of an electric signal sent on the surface of the wafer and the surface orientation is set on the base line of the stage. Consequently, the positioning in the wafer process has no trouble even without the OF surface.

IPC: A61M25/01
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To enable a guide wire to easily pass through a blood vessel even if the blood vessel is extremely thin, by composing the wire by a stranded wire shaft comprising plural wires. SOLUTION: A stranded wire shaft 11 is tapered at the tip end part, a core material 11 is made of stainless steel, and seven sets of seven stranded wires with the diameter 0.03 mm are collected and stranded. This guide wire comprises the base end part 11a with the diameter of 0.27 mm, the tip end part 11b with the diameter 0.03 mm, and the intermediate part with the diameter of 0.17 mm and worked to be stepwisely thinner toward the tip end by polishing or etching. A plug 13 is fixed with a tapering core material so as to have roundness toward the tip end direction at the tip end of the tip end part 11b and semispherical roundness is formed at the tip end by silver soldering, etc. When the guide wire is inserted into a blood vessel with extremely small curvature, the guide wire smoothly advances in the blood vessel to easily pass through even a bending part.  It is because the diameter of each wire constituting the stranded wire shaft 11 is so thin as to make the guide wire extremely flexible and soft.
