Title: Molding method of mold for reduced pressure casting
Inventor: BABA KAZUO
IPC: B22C3/00
Filed: 1980-08-11
Abstract: PURPOSE: To easily separate a pattern body clearly from a film shielding layer, by constituting a film shielding layer above a special pattern releasing layer set on the surface of a pattern body.  
     CONSTITUTION: A pattern separating layer 11 is formed on the surface of a pattern main body 10 for reduced pressure casting by means of a proper coating method with materials easy to change their physical properties such as dry ice or ice. In the next place, a liquidized film 12a is sprayed onto the surface of such pattern separating layer 11 by means of a spray gun, etc. and solidified there so as to form a film shielding layer 12. The pattern constituted through such processes is used as a conventional pattern for reduced pressure casting. When the pattern is drawn out of a mold, the pattern releasing layer existing in the space between the surface of the pattern main body 10 and the film shielding layer 12 is changed in physical property and liquidized and/or vaporized so that the separation of pattern from the mold can be easily conducted.

Abstract: PURPOSE: To effectively form, and to prevent from generating corrosion and rust, by bending the side rims of a metallic plate laminated with synthetic resin layer and simultaneously by applying a corrosion inhibitor.  
     CONSTITUTION: A side rim of a vinyl chloride laminated steel plate 1 is successively passed through the first group of die rollers comprising each pair of upper die roll A and lower die roll B to form side rims 2 of the steel plate 1 in a downward hanging shape, and is passed to the second group of die rollers comprising upper die roll A and lower die roll B. At roll B, a coating agent is applied at the tip of the rim side 2 is applied by the impregnated body 3 absorbed a corrosion inhibitor. Then it enters the third die rolls and successively formed to its destinated shape with its tip without coming in contact with other point on rolls.

IPC: H02M3/155
Filed: 1984-05-29
Abstract: PURPOSE:To effectively suppress a rush current by general parts by using high frequency switching such as transistors which gradually increase its duty cycles. CONSTITUTION:A controller 11 generates a high frequency pulse in a base drive control circuit of a transistor 10, and its duty cycle continuously gradually increases from 0% to 100% after a power source switch 2 is closed.

Title: Magnetic disk device
Inventor: UEMATSU YUKIHIRO
IPC: G11B33/14
Filed: 1982-06-25
Abstract: PURPOSE:To eliminate minute particles such as the mist which is mixed into an outside air or generated from inside of a magnetic disk device, by providing a filter containing active carbon inside a disk enclosure which is sealed up by a cover. CONSTITUTION:The outside air flowing inside through a breathing hole 1B from an outer wall OUT of a cover 1 toward an arrow b4 flows out to an inner wall IN of the cover 1 through active carbon 12 of a breathing filter 9. At the same time, a pierced hole 11A is set at an air path within the cover 1, the air can be transmitted in the direction of an arrow b5 or b6. The surface of the carbon 12 contains microminiature holes as in case when it is widely used as a deodorant. Therefore the carbon 12 absorbs satsifactorily the minute mist, etc. which produces odors. Thus it is possible to eliminate minute particles which are mixed into the outside air or generated inside a magnetic disk device.

Title: Wafer support having pressure zone where temperature feedback and contact area are small
Inventor: LUE BRIAN
IPC: H01L21/205
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To provide a method for controlling many pressure zones formed on the surface of a wafer support at specified pressures. SOLUTION: In order to control two zones 68 and 70 at different gas pressures, a sealing region 72 is formed between the two zones 68 and 70. High gas pressure is applied to the zone corresponding to a wafer W region to which mush heat should be transferred. The distance between a wafer support 64 and the wafer W is so determined that a specified amount of heat may be transferred to the wafer W. In the other conditions, the contact between the wafer supporter 64 and the wafer W is so controlled using projections 66 that a heat transfer gas flow may be maximum. A closed loop control system changes the heat transfer gas pressure according to a temperature sensor 96. Regarding an electrostatic chuck, the thickness of a dielectric body 86 can be varied so as to apply high electrostatic force to a peripheral region of the wafer W.

Abstract: PURPOSE:To enable to perform clean combustion through shortening of a flame even when an air ratio is low, by a method wherein a fuel port and an air port are bored on the same imaginary transverse cross plane, and at least the one is positioned on an imaginary straight line deviated to the one side from an imaginary straight line extending toward the axis of a combustion chamber. CONSTITUTION:A air port 2 and a fuel port 5 are positioned on the same imaginary transverse cross plane. Further, they are positioned on imaginary straight lines d1 and d2 which are deviated to one side in a direction of rotation about an axis O from imaginary straight lines C1 and C2, respectively, extending toward the axis O of a combustion chamber 1. In a pulse combustion condition, air-fuel mixture of fuel gas 1 and an air 13 is rotated in a manner shown by an arrow mark E, and thereby a flame 15 is started to rotate similarily in a direction shown by the arrow mark E. In which case, the fuel, which can not be mixed at a collosion part, is diffused at the downstream together with the air for combustion the flow in the combustion chamber 1 is turned in the direction of an arrow mark E, whereby violent diffusion is caused and a flame, formed at the downstream, is shortened. Additionally, the air and fuel gas are well diffused, and thereby unburnt gas is prevented from being exhausted till an air ratio is decreased to a low value.
