Patent JP-S56137677-A (JP)
Title: Manufacture of semiconductor device
Inventor: HAMAZAKI MASAHARU
IPC: H01L21/28
Filed: 1980-03-28
Abstract: PURPOSE:To reduce the level of a surface effectively by a method wherein a metal layer containing hydrogen all over is formed on the surface of an insulation layer and, after heat treatment being applied thereto, is patterned into a prescribed pattern. CONSTITUTION:The insulation layer is formed at least on one main surface of a semiconductor base body. Next, annealing treatment is applied thereto. This annealing is conducted in inactive gas. Then, the metal layer, e.g. of Al, containing hydrogen all over is evaporated on the insulation layer. Next, prior to the patterning of the metal layer, annealing treatment is applied thereto. This annealing treatment is conducted at N2 ro Ar gas. Thereafter, the Al metal layer is patterened into a prescribed pattern. In this way, active hydrogen produced on the Al-SiO2 interface is connected effectively with dangling bond, whereby the level of the surface can be reduced effectively.

IPC: C01B33/06
Filed: 1994-03-11
Abstract: PURPOSE:To produce a thermoelectric conversion material having high electric conductivity and low thermal conductivity and excellent in practicalness by coating the surface of silicide generating thermoelectromotive force with a layer having carrier mobility higher than that of the silicide powder. CONSTITUTION:After placing a silicide powder generating thermoelectromotive force in a powder vessel 202, a vacuum pump 42 is driven to produce a predetermined pressure in a reactor 200. A coating material and argon gas are then fed from cylinders 31, 51 into the reactor 200 through gas introduction pipes 204, 211. A predetermined high frequency voltage is then fed from a high frequency generator 11 to a high frequency coil 12 in order to generate plasma in the reactor 201 and the powder scooped up into the reactor 201 is brought into contact with the plasma. Since the powder is coated, through plasma processing, with a layer having high carrier mobility to produce a silicide powder (powder for thermoelectric conversion material), an excellent thermoeletric conversion material required for producing a thermoelectric conversion element having high electric conductivity and low thermal conductivity can be obtained.

Title: Swirl adjuster of washing water in washing machine
Inventor: FUJIMURA HISAKI
IPC: D06F37/08
Filed: 1995-01-22
Abstract: PURPOSE: To activate the movement of materials being washed and not to make the materials forced out from the washing water by fitting a plate to the specified position in the washing tank, making it function as a swirl adjuster for the washing water, and appropriately adjusting the form of water current. CONSTITUTION: With a place fitted to the specified position in the washing tank, the water current is changed from a centrally dented upright V-shape to a horizontal shape to heighten its water level. It means that the plate makes the washing water, surrounding the V-shape, come back to the center. Thus, it prevents the materials being washed from gathering and getting entangled, and disperses the materials in the upper part of water current. If the plate is fitted to be touched by a certain part of materials being washed, there is no such simple movement as gathering of materials at the center of swirl. Their rotation in the vertical direction is also generated so that the washing efficiency can be heightened.

Title: Driving method for stepping motor
Inventor: KOSAKA MASAYUKI
IPC: H02P8/38
Filed: 1985-03-04
Abstract: PURPOSE:To prevent a stepout by performing the rotation for generating a torque corresponding to a load applied to a stepping motor at rotation starting time, and the rotating by raising the rotating speed of the motor to the prescribed speed. CONSTITUTION:In case that a stepping motor 3 drives a mechanism for operating a print head 1 through planetary gears 8, 9 and a friction clutch, the maximum load from the mechanism is applied to cause the motor to be stepout when the motor is accelerated to become a high speed. Thus, the motor 3 is rotated at the prescribed low speed after acceleration. The torque of the motor 3 is sufficient to operate the mechanism. The prescribed low speed rotation is performed until passing the maximum load applied to the motor 3. Then, it is accelerated to the prescribed high speed rotation. Thus, the motor 3 is smoothly risen without stepout, and acceleration and constant high speed rotation are performed without defect.

Title: Production of vegetable juice
Inventor: HOSHIKAWA HIROYUKI
IPC: A23L2/02
Filed: 1988-02-26
Abstract: PURPOSE:To obtain a vegetable juice excellent in flavor and preservability, by dipping a vegetable into water having bean acidified to a specified degree with an organic acid, followed by squeezing and then sterilizing the resultant juice under heating. CONSTITUTION:A vegetable is dipped into water having been acidified to a pH <=4.0 with an organic acid and squeezed to produce a juice, which is then sterilized under heating. Although containing a small amount of micellanous bacteria, said juice is suggested to be put to the sterilization treatment under heating as quickly as possible. A preferable hot sterilization technique is, e.g., a heating at 90 deg.C for >=10min, or a second heating at 135 deg.C for >=30sec. using a high-temperature instantaneous sterilization treatment. Thus, the objective vegetable juice sufficiently sterilized with high preservability can be obtained. Treatment with an enzyme capable of obtaining clear juices such as pectinase has conventionally been made for the requirement of clearness of fruit juices or vegetable juices, this treatment, when needed, can also be applied in the above production process at any stage after the squeezing.
