Title: Formation of electrode of semiconductor device
Inventor: SUZUKI TETSUYA
IPC: H01L21/288
Filed: 1995-02-22
Abstract: PURPOSE: To easily obtain an ohmic contact between an electrode film and semiconductor film on a substrate by reductively removing a natural oxide film by applying a first voltage across a platinum electrode and plating electrode while a unit to be plated is dipped in a plating solution containing gold ions in such a state that only the part of an semiconductor film on which an electrode is formed is exposed, and then, precipitating gold by applying a second voltage across the electrodes. CONSTITUTION: A unit to be plated is composed of a semiconductor substrate 11, epitaxial layer 12, natural oxide film 13, plating electrode 14, insulating film 17, etc. When a first voltage, under which the natural oxide film 13 is reduced, is applied across a platinum electrode and the electrode 14 while the unit is dipped in a plating solution containing gold ions, the film 13 is reduced and the surface of the layer 12 on which a gold electrode is formed is exposed. When a second voltage, under which gold is precipitated on the surface of the layer 12, is applied across the electrodes thereafter, gold is precipitated on the surface of the layer 12 and an ohmic gold electrode 18 is obtained.

Title: Vessel
Inventor: HONDA SATORU
IPC: B63H25/38
Filed: 1981-04-16
Abstract: PURPOSE:To reduce the number of parts and shorten the time for mounting by shaping a turn-stopper means and a support member of a rudder shaft on an enclosing member in one body. CONSTITUTION:An enclosing member 20 of a propeller-check port 10 is overlaid upon a transom 9a and a ship bottom 9b to be watertight. Consequently, when some obstacle is involved in a propeller 11 and a shaft 11a, even if the propeller- check port 10 is opened to remove the obstacle, water is prevented from overflowing to the outside of the enclosing member 20. Since a flange 4 is fast fixed on an upper face 20b of the enclosing member 20, a rudder shaft 8 if free from vibration. A turn-stopper 23 convexed on the upper face 20b of the enclosing member 20 is designed to be as high as an arm 2 of a rudder 3. When the rudder shaft 8 is turned over a fixed angle, the arm 2 interferes with the turn- stopper 23 for preventing the rudder shaft 8 from turning excessively.

Title: Four-wheel steering device
Inventor: HIRAI TOSHIRO
IPC: B62D113/00
Filed: 1993-03-18
Abstract: PURPOSE:To enhance moderate converging performance upon rapid head turning and returning of steering at the time of further steering by setting a delay time constant according to the change direction of a steering angle, and computing a target yaw rate based on the delay time constant and a target yaw rate constant value. CONSTITUTION:A vehicle speed, steering angle and yaw rate arc detected respectively by means (b, c, d). A target yaw rate normal value corresponding to the detected vehicle speed and steering angle are computed by a means (e). Whether the change direction of steering angle is in the further steering direction or returning of steering direction is judged by a means (f). As a result, setting is made to a low value delay time constant at the time of further steering direction while setting is made to a high value delay time constant at the time of returning of steering by a means (g). With the target yaw rate normal value and the set delay time constant a target yaw rate is computed by a means (h). An auxiliary steering angle actuator (a) is feedback controlled by a means (i) so that the detection yaw rate corresponds with the target yaw rate.

IPC: B29L22/00
Filed: 1995-02-23
Abstract: PURPOSE: To make effective use of a resin squeezed out of a communication orifice and, also use the residual part of a floating core effectively by molding the floating core in a compatible resin with a resin used for molding with the floating core and also in the resin squeezed out of the communication orifice. CONSTITUTION: A floating core 1 is molded in a compatible resin with a resin used for molding. Consequently, it is possible to recycle a subsidiary molding as a molding material for a residual floating core 1, without the separation and removal of the floating core 1 from the subsidiary molding, if the floating core 1 is extracted in such a state that it is entered in a subsidiary cavity 4. In addition, if the floating core 1 is moved under pressure deep through the subsidiary cavity 4, without stopping the floating core 1 in a main cavity 5, a pipe intended for molding can be obtained in such a state that both ends are open only by cutting the pipe through a contracted neck part.

Title: Tappet valve device for internal-combustion engine
Inventor: NAKAMURA YUUICHI
IPC: F01L9/10
Filed: 1984-03-28
Abstract: PURPOSE:To dispense with the use of a gear train and thereby miniaturize the structure with reduced cost by operating a pneumatic pump by use of gas pressure in a cylinder and thereby driving a suction valve and an exhaust valve by making use of air pressure. CONSTITUTION:With cylinder gas pressure raised in its compression stroke of an engine, a first piston 2 is pushed up, and interlocking therewith a pneumatic piston 4 forcedly feeds air to an accumulator 10 to accumulate the air therein. The forcedly fed air from the accumulator 10 operates a second piston 12 for operating a suction valve or an exhaust valve 14 via a means 11 for controlling the amount of air and the timing for opening and closing the valves, and closes the valve 14. Thus, a cam shaft and a driving gear train therefor can go out of use, whereby engine cost can be reduced as well as an engine can be light-weighted and miniaturized.

Abstract: PURPOSE:To prevent the fogging and generation of an edge effect by using a two-component system non-contact developing method for forming a thin layer having gaps between the carrier particles and particles groups in a developing agent layer on the surface of a developing sleeve. CONSTITUTION:An electrostatic latent image carrier drum 1 and the developing sleeve 2 are rotated in the direction as shown by the arrows, the sleeve 2 is formed with a nonmagnetic electrically conductive substance, and a DC- superimposed AC bias 13 is impressed on the sleeve 2.

Abstract: PURPOSE:To pump up water efficiently by disposing a cylindrical air filtering wall at the lower portion of a guide tube for blowing out uniformly air bubbles from the entire inner face of the tube and mixing the air bubbles with water so that a composite specific gravity of the mixture is made smaller to produce buoyancy. CONSTITUTION:Air compressed to high pressure by an air compressor enters into an air chamber 3 through an compressed air inlet 1 of an air bubble type water pump, passes through a filter wall 4 having a lot of fine halls defined through it, and blows out into water in a form of fine air bubbles. At the instant, air bubbles out from the uppermost portion of the filter wall 4 reise along the inner wall of a guide tube 5 and air bubbles blowing out from under the uppermost portion rises through the inner side of the passage of the aforesaid are bubbles. As a result, when the height of the filter wall is equal to or longer than the radius of the guide tube, the air bubbles rise while making a uniform mixture with water quickly. Thus, the water pump produces a lot of fine air bubbles and mixes them with water uniformly for making a mixture of water and air bubbles so that a composite specific gravity of the mixture is smaller than that of water to produce buoyancy for permitting an efficient pumping of water.
