Abstract: PROBLEM TO BE SOLVED: To form a high-quality buried layer of the very low pinhole density, and improve the flatness of the interface between the Si layer and a buried silicon oxide layer. SOLUTION: In this manufacturing method, after the implantation of oxygen ions in the inside of a silicon substrate, a buried silicon layer is formed in the region at a specific depth from the surface of the silicon substrate, by annealing step raising the temperature up to a specific final temperature to be held for a specific time, so as to manufacture the SOI by forming an active Si layer on the substrate. At this time, the temperature increase rate is devided into at least two stages of v1 , v2 , to be increased successively decelerating until the final specific temperature T0 is attained. That is, the temperature is raised up to the first specific temperature T1 within the range of 1250-1350 deg.C at the initial temperature raising rate v1 of 10-3 deg.C/min, so that the final temperature increase rate v2 may be raised until the final specific temperature T0 of 1350 deg.C to silicon melting point temperature is attained at the rate v2 of 7-0.1 deg.C/min.

Filed: 1989-03-17
Abstract: PURPOSE:To keep off a paper jam in simplifying each mechanism around a paper winding shaft by winding a tip part of a journal sheet being fed out of a guide with a slit installed in the paper winding shaft. CONSTITUTION:A spool 8 is rotated and a slit 5 of a paper winding shaft 4 is opposed to a guide 2. A conveyor step motor 13 is rotated and a journal sheet is conveyed to the guide 2. Whether there is the sheet or not is checked by a paper sensor 3. When a tip part 1a of the journal sheet 1 being projected after passing through the slit 5 of the paper winding shaft comes to the required projecting length, the spool 8 is restarted. After several seconds elapsing, the conveyor step motor 13 stops its rotation. On the other hand, the spool 8 rotates, winding the journal sheet 1 on the paper winding shaft 4. When tension of the sheet is added to the winding shaft 4, a slip is produced in a clutch built-in this spool 8, so that rotation of a flange 6 in an integral construction with the paper winding shaft 4 comes to a stop.

Abstract: PURPOSE:To secure the same phase velocity for both the odd and even mode waves by drilling the hole at the area corresponding to the strip line and then filling the material having the higher dielectric constant than that of the dielectric into the hole, thus improving the directivity. CONSTITUTION:Dielectric 2 is put onto earthed conductor 1, and microstrip lines 4 and 5 plus dielectric 3 are deposited onto dielectric 2.

Then the hole is drilled to dielectric 2 corresponding to lines 4 and 5 and against dielectric 3, and then the material having the higher dielectric constant than dielectric 2 is filled into the hole. Thus a directional coupler is formed. The electromagnetic input is applied to input terminal IN of the coupler to produce the output signals from output terminals 11 and 12. And then the logic odd and even mode electromagnetic waves are propagated in the same velocity and along lines 4 and 5 in order to secure the same phase along the parallel field coupling regions. Thus the improvement is secured for the directivity.

Abstract: PURPOSE:To prepare an optical element having high precision in the process for prepg. an optical element by the reheat press method, by pressing and mold ing and optical element between dies from vertical direction, then shifting the pressing condition in the horizontal direction to remove the dies. CONSTITUTION:A material for lens 13 softened by heating is held at its periph ery with a member 14 and conveyed into between a pair of die 11, 12 facing each other in the vertical direction. Then, the lens material 13 is pressed from above and below by the dies 11, 12 to form a lens 131 having a desired shape. At this stage, a flange part 132 is formed around the periphery of the lens by a part of the material pressed out of the die 11, 12. Then, the dies 11, 12 are turned by 90 deg. while holding the lens in pressed condition, so the lens is now pressed from the horizontal direction. After holding the flange part 132 with a recovering holding member 115, the dies 11, 12 are separated to the original position, and the lens 131 is taken out. By this method, sticking of fine glass pieces or foreign matters such as dust generated by the shock at the stage of separation of the dies to the surface of the dies, is prevented. Embedding of such material in the surface of the optical element is also prevented.
