Title: Disk clamp device
Inventor: TANAKA SHINSAKU
IPC: G11B17/028
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a disk clamp device capable of attaching and detaching a disk to and from a turntable only by horizontally moving the disk. SOLUTION: The turntable 11 has a disk holding surface 12, an axial hole 15 to be fitted with a motor rotating shaft and a recessed part 17 positioned around this axial hole, and a clamper 10 has a pressing part 18 for holding the disk on the disk holding surface 12 and a projecting part 19 for inserting through a center hole 5 of the disk 2 into the recessed part 17. Centering of the clamper and the turntable is performed by engaging the recessed part 17 with the projecting part 19, and the projecting part is engaged with the center hole of the disk, so as to regulate the movement of the disk in the direction orthogonal to the axial center line, thus eliminating a part projecting largely from the disk holding surface on the side of the turntable.

Title: Manufacture of semiconductor device
Inventor: BOKU TAKAHIRO
IPC: H01L21/3205
Filed: 1989-11-10
Abstract: PURPOSE:To make the crystal structure of an Al electrode wiring layer that is formed on the surface of an interlayer insulating film uniform by forming protrusions on the surface of the interlayer insulating film. CONSTITUTION:An interlayer insulating film 2 is formed on the surface of a semiconductor substrate 1 and electrode windows 2a are formed in the above insulating film 2. Then, an Al electrode wiring layer 3 is formed after forming fine protrusions 2b on the surface of the film 2. Since these fine protrusions 2b hinder aluminum atoms from performing surface-diffusion and increase sites of crystalline nucleation when the film of the above wiring layer 3 is formed, the Al electrode wiring layer 3 holding the same crystal structure as that of a part where the electrode windows 2a are formed is formed on the surface of the interlayer insulating film 2 by controlling sizes of the fine protrusions 2b as well as intervals forming the protrusions. The formation of the above wiring layer 3, in this way, makes the sizes of crystal grains that are formed on the surface of the film 2 uniform.

IPC: H03H9/25
Filed: 1994-11-01
Abstract: PURPOSE: To obtain a coating structure for electronic device in which the case is not broken easily at the time of reflow soldering and the product is not damaged easily at the time of cleaning. CONSTITUTION: An electronic device 10 includes a case 12 having substantially U-shaped cross-section. Four ceramic elements 14 are arranged in the case 12, for example. The case 12 is provided, at the other end thereof, with a vent 24 for regulating the inner pressure.

Title: Work rotation positioning device in transfer press
Inventor: KURITA HIRAO
IPC: B21D43/05
Filed: 1992-10-06
Abstract: PURPOSE:To easily form an article to be press-formed without replacing a punch and a die in a punching process, and mechanical constituting parts in the punching process by rotating a punch composed of a butting member, a rotating member, a coupling member, a joining member and a stopping member by a required quantity. CONSTITUTION:When slide bars 35 and 35A move from the right to the left, this quantity of movement becomes the rotating quantity of a punch 11 through the projecting part of a slide block 33, a pin 20 and a lever 19. As the punch 11 goes up, a work 23 goes up while being held between the punch 11 and a seat 30. When the upper end of the seat 30 is in the same level as the upper surface of a die 26, the work 23 is held by fingers 32. Further, when the punch 11 goes up, since the pin 20 and the projecting part of the slide block 33 are disengaged, the punch 11 returns until the lever 19 butts a stopper 22 by the restoring force of a torsion spring 18. Next, during a period in which the punch 11 is at the top dead point, the work 23 is rotated by a specific angle, and an article to be press-formed is formed.

Title: Air filter material
Inventor: SHIMIZU MASAKI
IPC: B01D39/16
Filed: 1987-11-19
Abstract: PURPOSE:To increase efficiency of dust collection, reduce pressure loss, increase the capacity of the dust retention and extend the lifetime, by using an air filter material having the layers of fibers bonded together with an adhesive resin provided with expandable small spheres. CONSTITUTION:A material for use as an air filter has the layers of fibers such as a synthetic fiber and an inorganic fiber bonded together with a thermoplastic adhesive resin which is provided in the hollow interior thereof with expandable small spheres containing an inflating agent such as isobutane and azodicarbonamide and an initial pressure loss of not more than 100mmAq (when filtration velocity is 0.1-5m/sec). This results in increased apparent volume of the filter material due to the expansion of the expandable small spheres in the heating and drying processes and the voids thus retained in the fiber eliminates the clogging thereof resulting from a reduction in its thickness caused as in the conventional bonding method, leading to the retention of an appropriate density, improvement of dust collection efficiency, reduction of the pressure loss and extension of the lifetime.
