Title: Hub for optical disk
Inventor: FUKUSHIMA ISAMU
IPC: G11B23/00
Filed: 1993-12-21
Abstract: PURPOSE:To prevent the deformation of a hub and generation of crack occurring in stress and strain at the time of cooling after molding of the hub for an optical disk. CONSTITUTION:The hub 1 having an annular resin body 2 consisting of a synthetic resin and a magnetic annular body 3 consisting of a magnetic material coaxially formed on its one plate surface is provided with a recessed part 4 extending in a circumferential direction on the plate surface of the annular resin body 2 on the side opposite to the surface disposed with the magnetic annular body.

Inventor: KUSAKA KENSAKU
IPC: H05B3/16
Filed: 1989-12-11
Abstract: PURPOSE:To enhance the safety and reliability of a heater and a device using it, by forming a fuse in close contact with the heater, shutting the surrounding of the fuse from external air by a covering member with a space interposed, and installing a temp. sensing element in a well-deviced arrangement. CONSTITUTION:A current-fed heat emitting body 23 having a low heat capacity is printed linearly on the undersurface of an alumina base board 22. A fuse 33 and electrodes 31, 32 are provided on the oversurface of the base board 22 in the neighborhood of a thermistor (temp. sensing element) 24 while in close contact with the surface of base board. The whole fuse 33 is sealed airtightly with glass 34 and heat resistant adhesives while a space 37 is interposed, and Ar is encapsulated in this space. A control circuit 35 controls a switching element 36 appropriately in conformity to the heater 21 temp. information given by a temp. sensing element 24, and thereby current feed to electrodes 23a, 23b of the heat emitting resistance body 23 is controlled. Thus the temp. of the heater 21 is adjusted within a specified control range, wherein the fuse and base board have approx. equal temp. because the fuse 33 is in close contact with the base board 22 and the heat capacity of itself is small. The fuse attains the same temp. as the heater without delay substantially at overrising of heater 21 temp. and blows at a certain temp. to shut the current feed.

Title: Manufacture of semiconductor device
Inventor: KIMURA TAKEMI
IPC: H01L27/04
Filed: 1988-12-20
Abstract: PURPOSE:To make an element flat by separately forming a high resistance value region and a low resistance region, removing a mask material, and thereafter patterning a polycrystalline silicon layer. CONSTITUTION:A polycrystalline silicon layer 3 is mounted on a semiconductor substrate 1 through an insulating film 2. A silicon dioxide film 4 is selectively formed on the layer 3. With the film 4 as a mask material, phosphorus ions having a high concentration are implanted, and a region which is to become a low resistance region is formed. At this time a part of the polycrystalline silicon layer 3 beneath the silicon dioxide film 4 wherein the ions are not implanted becomes a high resistance region. The silicon dioxide film 4 is removed. Then, photolithography technology is used, and the region which is to become the high resistance region and the region which is to become the low registance region in the polycrystalline silicon layer 3 are patterned at the same time. Since the mask material 4 is removed after the ion implantation, the surface of the element is flat, and the deterioration in yield and reliability of the elements can be prevented.

Title: Method for evaluating coating film decomposition degree of regenerated plastic material with coating film
Inventor: SATO NORIO
IPC: B29B15/00
Filed: 1992-12-03
Abstract: PURPOSE:To simply and rapidly evaluate a coating film decomposition degree when a regenerated material is produced by decomposing a coating film of a coated plastic waste. CONSTITUTION:A coating film of a thermoplastic plastic waste coated with a thermosetting resin film is decomposed. This is melted and kneaded without removing the coating film to be produced as a regenerated material (sample resin) G. A fixed amount of the regenerated material G is put in a container 3 having a delivery hole 1 with a mesh 5 attached on the bottom thereof and melted. The melted regenerated material G is extruded from the delivery hole 1 through the mesh 5 by a plunger 4. While the extrusion load of the plunger 4 at this time is kept constant, a coating film decomposition degree is evaluated by an elapse time or a time change pattern until the discharge of the melted regenerated material G in the container 3 from the delivery hole 1. Alternatively, while the extrusion speed of the plunger 4 is kept constant, a coating film decomposition degree is evaluated by a load or a load change pattern of the plunger 4 during the discharge of the melted regenerated material G in the container 3 from the delivery hole 1.

Title: Air pressure transfer device for individual cargo
Inventor: DEIITERU HIIPU
IPC: B65G53/52
Filed: 1993-12-22
Abstract: PURPOSE: To quickly unload a blockage so as to prevent damage to bulk material and the failure of an apparatus by pre-adjusting the closing forces of overflow valves so that a spring force corresponds to the difference between conveying force in a conveying piping or static pressure in an associated line and the pressure of each overflow valve within the conveying piping. CONSTITUTION: When a blockage 16 occurs in a piping, e.g. on an overflow valve 23, a pressure curve differing from an idealized pressure curve 19 is generated. Overflow valves 20, 21, 22 are closed as the result of a pressure buildup in front of the blockage 16 and the overflow valves 23, 24, 25 are opened as the result of a decrease in pressure downstream of the blockage 16. In the blockage 16, a position 29 is moved to a position 29' by the pressure decrease and the overflow valve 23 is opened by the force P' of the pressure differential. Since high-pressure conveying air is fed into a conveying piping 5 through the overflow valve 23 via a branch pipe 15, the blockage 16 is decomposed and thereby eliminated.
