IPC: H01L21/338
Filed: 1990-11-02
Abstract: PURPOSE:To improve withstand voltage characteristics by forming recessing a semiconductor substrate with source and drain regions at both ends of a recess and by forming a channel region in the substrate with a Schottky gate in the recess. CONSTITUTION:For example, a semiinsulating arsenic gallium substrate 1 is recessed, and a recess is coated with a silicon dioxide film. Next, silicon ions are implanted to form a source region 4 and a drain region 5 on both sides of the recess, and an n layer 6 serving as the channel under the recess. After the silicon dioxide film is removed, the whole face is spread with a silicon nitride film and then rid of the flat zone, leaving a silicon nitride film at a recess end of form an opening. Thereafter, a gate electrode material is deposited flat to form a gate electrode 9 by dry-etching. Further, a source electrode 10 and a drain electrode 11 are formed. This can provide an excellent withstand voltage characteristics with less manhour.

Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To stably install a step in the step difference between a road and a footpath by providing a height adjusting means to the leg part which has been provided to the one side part of a step body of a flat-plate shape. SOLUTION: A step A is installed on a L-shaped groove B by adjusting the height adjusting screw 2b of the leg part 2 of the step A so as to fit the depth of the L-shaped groove B, so that the step difference between the step A and the L-shaped groove B is not caused. Even if the step body made of steel plate is deformed by a load and the leg part 2 is floated up, the play can be eliminated by finely adjusting the height of the leg part 2. Even if there is an unevenness in the surface of the L-shaped groove B, the play can be eliminated in the same manner. Thus, the step can be stably installed in the step difference between a road and a footpath.

Title: Mold and method for taking sample for element analysis from molten metal
Inventor: ASANUMA YOSHIRO
IPC: G01N33/20
Filed: 1990-11-07
Abstract: PURPOSE:To enable prevention of sticking and solidification of a metal and to facilitate takeout of a sample by making the upper end part of a sample mold have an acute-angle structure. CONSTITUTION:The upper end part of a main body 2 made of steel is made to have an acute-angle structure 4 and each part of the main body 2 is made to differ in a thermal capacity from others. Due to this difference, some difference occurs in solidification of molten steel taken out. In other words, the molten steel which is about to solidify while overflowing on the upper end part of a mold 1 flows down without staying on the part of the structure 4. Accordingly, a steel sample 5 solidifying in a cavity 3 is independent of a metal sticking on the lower lateral part or the bottom part of the mold 1, a handle or the like temporarily, and thus takeout of the sample 5 is facilitated.
