Title: Servo pattern writing device
Inventor: MIYASAKA TAKASHI
IPC: G11B23/30
Filed: 1986-06-19
Abstract: PURPOSE:To obtain a servo pattern writing device capable of neglecting the azimuth loss of a bit of servo information, by writing a serve pattern by using a magnetic head mounted at a magnetic head mounting part in a magnetic disk device. CONSTITUTION:A magnetic disk 11 is mounted on a spindle motor 13 fixed at a base plate 12. A sub assembly mounting a magnetic head actuator 15 on which a magnetic head 14 is mounted, rotatably centering a pivot part 16, is fixed on a positioning board 17 by a clamper 18. By coupling an external actuator 19 with the magnetic head actuator 15, and moving the actuator 15, the servo pattern is written by the magnetic head 14. Therefore, since the readout of the servo pattern is performed at the same position, and by the same magnetic head as at time of writing, an zimuth angle goes around to zero, thereby, the azimuth loss can be neglected.

Title: Pressure drive baffle seal
Inventor: BURUUSU DABURIYUU BUAISU
IPC: F28F9/24
Filed: 1988-06-13
Abstract: PURPOSE: To obtain a seal that is driven by a pressure for increasing the sealing force in a radiating direction in response to the increase in the difference in a fluid pressure being generated across a baffle, by providing a thin, flexible tongue around a hole that is formed at the baffle of a heat exchanger consisting of a shell and a pipe. CONSTITUTION: A baffle 16 is made of a plastic member, a seal 46 that is integrally formed with it has a thin, flexible annular tongue 48, and a non-extension inner diameter 50 of the tongue 48 is smaller than an outer diameter 42 of a pipe. When a pipe 14 is inserted through a hole 34, the tongue 48 is extended outward in a radiating direction and is extended in an upstream direction. A rear side 64 of the seal lip 48 touches a downstream, low pressure, and a front side 66 is exposed to a high upstream side. The pressure difference presses the seal tongue 48 downstream in a radiation direction for the pipe 14, thus forming a seal being driven by pressure. Further, the center unevenness of the pipe for the hole of the baffle can be coped with and when inserting the pipe into the hole of baffle, the force in the axial direction is decreased to minimize the damage to pipe fins.

Title: Memory unit
Inventor: KAMITSUMA YUUSUKE
IPC: G06F12/06
Filed: 1977-12-02
Abstract: PURPOSE:To shorten a write time by starting a write operation right after a write signal arrives with no write-signal acceptance time by equipping a memory unit, used by various equipments in common, with a timing control circuit exclusively used for the write operation. CONSTITUTION:Once receiving starting signal 10, read-operation control circuit 5 generates timing used for both read operation and write operation. Receiving a write signal within the write-signal acceptance time, write-operation control circuit 6 inhibits immediately read-operation control circuit 5 from starting its read operation. Write information is fetched in formation control circuit 4 and then sent to memory part 3. Next, the timing needed for writing is sent to memory part 3 via driver circuit 2 and the write operation is finished within a fixed time by the write signal.

IPC: C01B19/04
Filed: 1993-06-16
Abstract: PURPOSE:To shorten the sintering time remarkably by loading more than one kind of laminar material powder, selected from a silicon-germanium based material, an iron-silicide based material, a lead-tellurium based material and a bismuth-tellurium based material, into a reaction tube and then subjecting the material powder to sintering. CONSTITUTION:A mold having strength high enough to withstand the sintering conditions of conductive carbon or carbide is employed in a PAS system. More than one kind of laminar material powder is loaded into a carbon die 1 constituting the PAS system and then subjected to plasma sintering thus producing a thermoelectric conversion material efficiently through a simplified process. In other words, molding and sintering can be effected simultaneously, especially at a temperature lower than the melting point, by simply loading the material powder in layer into the reaction tube (A). This method allows remarkable shortening of the sintering time to 10min or thereabout thus realizing effective thermoelectric conversion from low temperature region to high temperature region.

Title: Coupling receiver for panel
Inventor: SANOU TOSHIO
IPC: B62D65/00
Filed: 1979-11-07
Abstract: PURPOSE:To prevent the recessing of the panel due to the partial contact of other panel by burying a rigid material in a portion corresponding to the partial contact portion of the panel in a coupling receiver made of a soft material. CONSTITUTION:When coupling the outer panel 12 with the inner panel 13 of automobile hood, the outer panel 12 is first delivered from a feeder and placed on a receiver 11, and then the inner panel 13 is dropped from another feeder onto the outer panel 12, whereupon the inner panel 13 is partially contacted with the outer panel 12 but impact entailed is received by a rigid material 15 because the partial contact portion of the outer panel 12 is contacted with the rigid material 15 buried in the receiver 11. Thus, the partial contact portion of the outer panel 12 does not penetrate into the receiver and therefore, no recessing is formed.

Filed: 1990-06-01
Abstract: PURPOSE:To enhance cooling effect by inflating approximately guadraspherical shell type blades from a cooling fan thereby surely taking in outer air upon rotation of yoke. CONSTITUTION:Same number of blades 15 as the vents 12 made through a yoke 3 are disposed, oppositely to the through-holes 12, on the body 14 of a fan 13. The blades 15 are inflated from a part of the bottom of the body 14 in the form of approximately guadraspherical shell shape as shown on the drawing. The blade 15 is provided with a function chamber 16 communicated with the vent 12, where the function chamber 16 is defined by the shell wall 16a opposing to the vent 12. When the front sidewall is opened, the function chamber 16 takes in outer air through a suction port 16b and feeds the air axially inward toward the vent 12 through a delivery port 16c. Since the outer air can surely be taken in as the yoke rotates, cooling effect is improved.

IPC: H03J7/02
Filed: 1982-08-20
Abstract: PURPOSE:To avoid the change of channel selection state up to the outside of a pull-in range even though the received radio wave does not exist any more, by stopping an AFC operation when the shift degree of frequency is larger than a prescribed frequency. CONSTITUTION:A microcomputer 5 decides and stores the shift degree of the present frequency to the center frequency. Then the frequency dividing ratio is corrected to raise or lower the tuning frequency by 50kHz in case the AFC voltage is higher than the reference level and at the same time the shift of frequency is within 800kHz. If the frequency shift exceeds 800kHz and is outside a pull-in range of the AFC operation, no correction is given. Then the dividing ratio of a frequency divider 8 is set at the value corresponding to the center frequency of the relevant channel.

Abstract: PURPOSE:To density materials after firing and to inhibit changes in bond strength with time, by using a metallic powder composed of an electrically conductive metallic powder and alloy powder thereof as a metallic powder which is a main component of the electrically conductive paste. CONSTITUTION:A metallic powder (A) composed of an electrically conductive metallic powder (e.g. copper powder) and its alloy powder (e.g. copper/cadmium alloy powder or copper/silver alloy powder), glass powder (B) as an adhesive, an org. binder (C) (e.g. ethylcellulose) and a solvent (D) (e.g. turpentine oil) are mixed together to obtain the desired electrically conductive paste. When the paste is applied to a substrate and baked, the growth of the particles of the metallic powder takes place while the growth of the particles of the alloy powder is light, so that the alloy powder acts to clog the spaces between metallic particles, thus forming a dense conductive pattern.
