IPC: H01L21/20
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To sharply minimize a leakage current by a method wherein the 0001 surface of a silicon carbide single crystal of a hexagonal crystal or an equivalent surface thereto is made the main surface, a groove part is formed thereon and a sidewall of the groove part is made parallel with the surface with a face index 1-100 of the silicon carbide single crystal or an equivalent face thereto. SOLUTION: In contact with an n-type layer 11 having low resistivity an n-type drain layer 12 having higher resistivity than this layer is provided. On the source side, a groove part 16 is formed and the semiconductor surface has projections and depressions. A n-type source layer 14 is formed on a region of the main surface 20 of the projection part by ion implantation and a p-type layer 13 is formed on the base part of the groove part 16 by epitaxial growth. At this time, the main surface 20 is made to be parallel with a hexagonal crystal silicon carbide 001 crystal face and a side wall 21 of a groove part 16 is to be parallel with a 1-100 face.  Thereby, even if a pn junction face with a p-type layer may become zigzag, there is no danger of causing breakdown due to the concentration of an electric field on the projection part so as to sharply minimize a leakage current and improve reliability.

Title: Recorded signal reproducing method for optical recording medium
Inventor: KAWASAKI YORIJI
IPC: G11B11/10
Filed: 1993-12-27
Abstract: PURPOSE:To reduce reading errors of an optical disk reproducing device. CONSTITUTION:Plural reading laser spots are arranged with an interval on the same reading track of a medium by a diffraction grating 3 in an optical head or a laser diode array. Reflected light beams from the respective laser spots are received by respective photodetectors 9a, 9b and 9c in the optical head and the same information is reproduced with a time difference. The plural reading signals are compensated for the time differences by using delay circuits 11a and 11b, and based on the averaged value or the majority value of each signal value, the most probable signal is outputted as a reproduced signal output. Thus, signal having a very small effect caused by random errors is reproduced.

Title: Single lever mixing valve
Inventor: NAKANO TOMOAKI
IPC: F16K11/06
Filed: 1992-12-10
Abstract: PURPOSE:To apply resistance to the closing operation of a movable valve, and prevent the occurrence of a water hammer phenomenon at the time of closing the valve or stopping water by providing a piston type resistance mechanism between an operation block integrated with the valve and a guide ring for guiding the block. CONSTITUTION:A lever 4 is pushed down to shift a movable valve plate 3 from a wafer stop position to various positions, and also turned to set a ratio of water and hot water quantities. At the time of service, water and hot water respectively flow from the water port 2a and hot water port 2b of a stationary valve plate 2 to a housing 1, and are delivered from a mixing water outlet 2c via the communication port 3a of the movable valve plate 3. When the lever 4 is pulled up to perform a valve closing operation, an operation block 7 moves right, and the movable valve plate 3 is thereby caused to return to the water stop position. In this case, the bore 7b of the block 7 moves in a direction for housing a piston 8 and, therefore, water in the bore 7 is discharged through a small hole 7c, thereby applying resistance to the block 7. As a result, the movable valve plate 3 gradually closes.

Thereafter, grout is filled between the vertical pile 10 and the sheath pipe 38 so as to fix the upper structure part. A splice pipe 44 is inserted in a through-hole 40, and is welded to the inclined pile 12. Concrete is placed between the through-hole 40 and the splice pipe 44 which is therefore fixed to the dolphin body 14a.
