Title: Polishing method for semiconductor substrate
Inventor: SATO HIROSHI
IPC: B24B37/07
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a polishing method by which a film thickness of a concave- shaped silicon wafer base plate, in which a film thickness in the center part, is reduced by grinding, can be corrected to a uniform thickness. SOLUTION: When a base board to be polished is polished by using a polishing device 20 in which polishing is carried out by means of a rotary polishing surface plate 21 and polishing liquid L, in a raw plate 1A serving as the substrate to be polished, an outer circumference of the face to be polished is polished at a rotational speed higher than that for the polishing surface plate 21 in the direction reverse to the rotating direction of the polishing surface plate 21. If the thickness of the outer circumferential face reaches a thickness of the center part or less, the raw plate 1A is rotated in the same direction as the polishing surface plate 21 at the rotational speed for a rotation area in which respective points on the surface rotate at the same relative speed, and as a result, the thinned face to be polished is polished.

Title: Pipe for transporting sunbeam into room
Inventor: SUGANO AKIHIRO
IPC: G02B27/00
Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To easily guide the sunbeams to a place where the sunbeams do not arrive by an ordinary method and to obtain illumination, sterilization and thermal effects, etc., by forming a mirror for reflecting the sunbeams on the inside surface of a hollow pipe, thereby forming a sunbeam transporting pipe. SOLUTION: The light increased in the sunbeam density by a device 6 for condensing and following up the sunbeams is admitted from a conical pipe 4 through a sunbeam inlet into the sunbeam transporting pipe 3 and is introduced to a sunbeam outlet 3 while the light is reflected successively at the mirror on the inside surface of the sunbeam transporting pipe 3. The light is then released from this outlet. The sunbeams are condensed and the powerful light having the high density is introduced into the sunbeam transporting pipe 3, by which the light quantity released by reaching the sunbeam outlet is compensated. The sunbeam transporting pipe 3 is capable of transporting the sunbeams of the intensity appropriate for practicable use.  The sunbeam components are separated and diffused at every reflection on the mirror but all of the sunbeam components eventually reach the sunbeam outlet and are released because of the in-pipe sepn. and diffusion in the sunbeam transporting pipe 3.

Title: High-speed large-current switch
Inventor: FUJIWARA SHUZO
IPC: H01H39/00
Filed: 1989-09-29
Abstract: PURPOSE:To quickly cut off currents by means of a current limiting effect and obtain a high-speed large-current switch of high performance by generating frictional heat by means of a motive force generated by an explosive so as to enhance the resistance of a current limiting material, and further moving a working body so that the working body is not in contact with electrodes. CONSTITUTION:When a working body 11 is moved by the action of an explosion force generated by explosion of an explosive frictional heat is generated in the contact face if the working body with the electrodes of a current limiter 6 and the temperature of a current limiting material is raised and sodium and/or calium are converted from solids to liquids and are further converted to gases and a large current flowing through the current limiting material exhibits a current limiting effect. The working body 11 is further moved and is mechanically separated from the current limiting element, while the large current is limited by the current limiter 6. Thus the large current is cut off at high speed without generating an arc.

IPC: H03K17/56
Filed: 1984-11-30
Abstract: PURPOSE:To prevent signal propagation delay by constituting a short-circuit of a primary coil of the primary side of a pulse transformer in switching an output signal from 'H' to 'L' so as to short-circuiting an induced voltage due to the residual magnetic flux of the pulse transformer and eliminating it. CONSTITUTION:Suppose that a switch S4 is kept ON and a switch S1 is turned off while obtaining an 'L' output with switch pairs S1, S4 turned on and switch pairs S2, S3 turned off. Then a current flowing in the path of power supply E - switch S1 - pulse transformer PT primary winding - switch S4 - power supply E will continue by the residual magnetism of the transformer PT due to said current. Thus, said current flows in the path of PT primary winding - switch S4 - diode D2 - PT primary winding. As a result, the primary winding of the transformer PT is short-circuited, the induced voltage due to the residual magnetic flux of the PT is short-circuited. Then no signal propagation delay is caused.

Abstract: PURPOSE: To always obtain stable coupling at the time of longtime use by assembling a thermoelectronic cooling element itself with an Sn/Sb solder and using a Pb/Sn solder to fix a stem and the thermoelectronic cooling element and fix the thermoelectronic cooling element and a case. CONSTITUTION: A thermoelectronic cooling element 5 itself is assembled with a Sn/Sb solder having solidus temperature of 232 deg.C, and a Pb/Sn solder 14 having solidus temp. of 183 deg.C is used as the joining member between a stem 4 and the thermoelectronic cooling element 5 and that between the thermoelectronic cooling element 5 and a case 6. Since the thermoelectronic cooling element 5 assembled by the Sn/Sb solder having a melting point higher than that of the Pb/Sn solder is used, the Pb/Sn solder 14 which has a higher solidus temperature and about 650-fold creep strength in comparison with a conventional In solder can be used to fix the step 4 and the thermoelectronic cooling element 5 and fix the thermoelectronic cooling element 5 and the case 6. Thus, the optical axis disalignment due to displacement of fixed parts is reduced at the time of longtime use.

Abstract: PURPOSE:To prevent the concentration of an electric field at the corner of an electrode by forming a thermal oxide film on a first electrode before forming a dielectric film, then removing the oxide film, and then forming the dielectric film made of a silicon nitride film. CONSTITUTION:An insulating film 6 made of a silicon oxide film is formed on a silicon substrate 5, a polysilicon film is formed on the film 6, phosphorus ions are implanted, and nitrogen-annealed so as to further activate the impurity. Then, it is patterned by anisotropically etching to form a first electrode 1. Thereafter, the electrode 1 and the substrate 5 are thermally oxidized to form a thermal oxide film 2. Thus, the corner A of the upper face of the electrode 1 is oxidized faster than the flat face to be rounded. Subsequently, the film 2 is removed. Thus, the corner of the upper face of the electrode 1 is rounded. Further, a dielectric film 3 made of a silicon nitride film is formed by a CVD method employing silane and ammonia. Eventually, a polysilicon film is formed thereon, thereby forming a second electrode 4.
