Abstract: PURPOSE: To manufacture a sufficiently-reliable IGFET with a nealy-flat difference in level between its gate, and source and drain.  
     CONSTITUTION: On p-type Si substrate 1, SiO 2  2, Si 3 N 4  3 and SiO 2  4 are stacked. Next, an opening is made in film 4 and then opening 5 is made to form concave 6 in the Si substrate. Films 2 to 4 are removed and SiO 2  7, poly-Si 8 and SiO 2  9 are stacked. Films 8 and 9 are removed selectively by being photo-etched to form SiO 2  9' and gate electrode 8'. Next, phosphorus is diffused to substrate 1 and film 8' through films 7 and 9' to form N-type layer 10' and 11. Then, windows are made in surface oxidized films 12 to 14 and Al wirings 15 to 17 and ohmic electrode 18 on the reverse surface of substrate 1 are provided respectively, so that the entire process will be completed. Consequently, gate electrode 8' is buried between source and drain 10 and 11, and the difference in level between the gate part and source and drain electrodes lessens, so that the breaking of wiring will be reduced.

Abstract: PURPOSE:To carry out observation equivalent to a case in which an object to be inspected is irradiated with a laser beam having the uniform intensity distribution notwithstanding that laser beam intensity presents the gauss distribution by moving light flux along plural cross sections while radiating the laser beam, whose light intensity presents the gauss distribution in the radial direction of the light flux, to the object to be inspected. CONSTITUTION:A laser device 201 radiates a laser beam 203 whose light intensity presents the gauss distribution in the radial direction of light flux. The laser beam 203 is condensed by a condensing lens 207 so as to have a prescribed light flux radius in an illuminating part 205. A stage device 211 moves light flux of the laser beam in the illuminating part 205 along plural cross sections of an object 209 to be inspected having an interval almost equal to the radius. Scattered light from the illuminating part 205 forms an image by a microscope 215, and an image signal is outputted by a TV camera 217. When the illuminating part 205 is set in an initial position on a desired cross section of the object 209 to be inspected, a computer 213 takes in and stores a signal from the camera 217 while moving the device 211.

Title: Cpu and microcomputer
Inventor: KAWASAKI SHUNPEI
IPC: G06F9/35
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To prevent the utilization of immediate data or the designation of an absolute address from being limited even when the number of bits of a fixed length instruction format is less than the data word length, by adopting the fixed length instruction format having bits less than the maximum data word length supplied to an instruction executing means. SOLUTION: IRH and IRL are the instruction buffers of 16 bits respectively, and an instruction is transferred through an internal data bus for the unit of 32 bits while being stored one by one. These instructions are loaded through a multiplexer MPX to an instruction register IR1. The instruction register IR1 has 16 bits. Thus, since the fixed length instruction format of 16 bits is adopted for the data word length of 32 bits, the judgement on where an instruction border exists, can be grasped before the completion of the preceding instruction, and the advantage of the simplification of instruction decode processing or the like is guaranteed. Further, the useless arrangement of bits is decreased and the utilization efficiency of a program memory is improved.

Title: Axial flow type air pump
Inventor: SUGIHARA TAKESHI
IPC: F04C18/16
Filed: 1986-07-08
Abstract: PURPOSE:To make large discharge pressure securable, by letting three rotors, being increased by degrees in proportion as torsion of each rotor shifts from the suction side to the discharge side, slidingly contact with one another, and making them perform synchronous rotation of the same phase. CONSTITUTION:An axial flow type air pump is provided with three rotors 2-4. Each rotor is formed into the sectional form partitioned off by three convex curves setting a radius of curvature and length down to the same each. And, the drum form part form is formed into such a torsion form as increasing the extent of torsion by degrees in proportion as it shifts from the suction port side to the discharge port 13 side. When each rotor is rotated via gears 14-16 and turning shafts 5-7, plural operating chambers formed by these rotors themselves in the axial direction shifts from the suction port side to the discharge port 13 side. At this time, the torsion of each rotor grows large, insomuch that it goes toward the side of the discharge port 13, and since the degree of decrement in displacement of the operating chamber becomes larger, large discharge pressure is thus securable.
