Title: Production of metallic seal having contracted part
Inventor: MICHIHIRO MASAMI
IPC: B22D13/04
Filed: 1983-11-19
Abstract: PURPOSE:To cast large quantities of metallic seals with one time of pouring and to improve working efficiency by pouring a molten metal into a pouring chamber of a rotating body, introducing the molten metal by centrifugal force into plural casting molds to form the metallic seals then decreasing the temp. to shrink the molten metal and removing the seals from the molds. CONSTITUTION:When a molten metal is pured into a pouring hole 2 in the central part of a rotating body 1 while said body is rotated at a prescribed speed, the molten metal given centrifugal force by the rotation is kicked into the holding core 10 part in the chamber 2 and flows through a well part 11 and a gate part 12 into casting molds thereby forming metallic seals 8. Each seal 5 is gradually cooled and cured and since the seal shrinks upon curing, the outside circumferential part of the seal 8 is detached from the inside circumference forming part of a master mold 5 thus producing a gap (a). If the diameter of the projecting part (c) of the master mold 5 for forming the contracted part (b) of the seal 8 is set larger than the diameter of the projecting part (d) of the upper stage for forming the part (b) of the seal 8 upon completion of shrinkage, the engagement between the part (b) of the shrunk seal 8 and the forming part on the inside surface of the mold 5 is removed and the mold 5 is removed upward while the seal 8 is left on a drag 6.

Title: 3-phase reluctance type motor
Inventor: BAN ITSUKI
IPC: H02P6/16
Filed: 1989-08-28
Abstract: PURPOSE:To reduce the diameter of a motor and to prevent generation of reverse torque by providing two reluctance type motors in an outer housing, and circulating magnetic energy stored in an exciting coil back to a high voltage DC power source. CONSTITUTION:Two 3-phase single wave conduction reluctance type motors are aligned in parallel in an outer housing. Accordingly, the number of poles and the number of salient poles per one motor are reduced to 1/2, and its diameter is decreased, but output torques are the same as that for 3-phase full-wave conduction. When the input of an input terminal 4a is erased, magnetic energy stored in an exciting coil K is conducted in the order of a diode 21b   power source terminals 2a, 2b   a diode 21a since transistors 20a, 20b are both interrupted, and the energy is circulated to the power source. The higher the power source voltage is, the smaller the width of the drop of a curve 35a becomes. When the width of the drop is so set as not to exceed 30 degrees (the width of an arrow 36a), generation of reverse torque is prevented.

Title: Manufacture of semiconductor element
Inventor: TAI KAORI
IPC: H01L21/3205
Filed: 1997-08-14
Abstract: PROBLEM TO BE SOLVED: To provide a manufacture method which can inexpensively manufacture a semiconductor element having an adhered layer, where contact resistance does not increase or a diffusion layer is not damaged, even if high temperature heat treatment is executed in a short time. SOLUTION: A titanium nitride layer constituting the adhered layer is set to be a stack structure of first to third titanium nitride layers 104-106, and a second film forming condition used for forming the second titanium nitride layer 105 is made different from a first film-forming condition used for forming the first and third titanium nitride layers 104 and 106. Thus, the grain of the second titanium nitride layer 105 is made smaller than the grain of the first (third) titanium nitride layer 104. Since the titanium nitride layer, where the grains discontinuously grow, is formed only by temporarily changing the film forming condition, the semiconductor element having such a characteristic can inexpensively be manufactured in a short time.

Abstract: PURPOSE:To control the position of a light beam toward the center of a track and to ensure the working stability and the reliability of an optical information recording/reproducing device, by using a means which can control the positions where >=2 light beams irradiate an information recording medium. CONSTITUTION:The reflected light sent from a disk 20 is reflected again by a half mirror 7 after passing through an objective lens 10, etc. Then the reflected light is detected by a photodetector 13 and turned into the FES and the TES to act on the actuator driving coils 54 and 55 via servo circuits 50-53. Thus the lens 10 is moved and the light beam is irradiated properly on a track 21 of the disk 20.
