Title: Production of vegetable oil
Inventor: SUZUKI SHIGEMI
IPC: B01D61/14
Filed: 1990-09-26
Abstract: PURPOSE:To economically and rapidly obtain high-quality vegetable oils with hardly any contamination of phospholipids, etc., by permeating miscellas prepared from plant seeds through an ultrafiltration membrane at a specific temperature and then removing impurities in the miscellas. CONSTITUTION:Plant seeds such as soybean, rapeseed, safflower, corn, sunflower or rice bran are extracted with an organic solvent preferably composed of n-hexane to provide miscellas, which are then heated at 50-120 deg.C (preferably 50-90 deg.C). In this state, the miscellas are subsequently permeated through an ultrafiltration membrane composed of an inorganic micromembrane having 30-100Angstrom pore diameter.

Title: Semiconductor integrated circuit
Inventor: KAMIOKA JUNJI
IPC: H01L29/78
Filed: 1989-09-28
Abstract: PURPOSE:To prevent the electric field concentration between an input gate and a source diffusion layer by putting a MOS transistor, which gets in ON conditions at normal operation, between a source electrode and a power source or an earth electrode. CONSTITUTION:A P-type MOS transistor QP1 and an N-type MOS transistor QN1 constitutes an inverter circuit, which shares common input and output terminals, and the gate input is connected to an input pad through a resistor R, and is connected to the earth through an N-type MOS transistor QN0. The gate of the N-type MOS transistor QN0 is fixed to the earth, and it is off in usual operation, but in case that excessive voltage is applied between the input and the earth, the line between a source and a drain breaks down, whereby it protects the input gate of the inverter circuit. Usually, a P-type MOS transistor QP2 is ON with the gate fixed to an earth level, and is put between the source of the P-type MOS transistor QP1, which constitutes the inverter circuit, and the power source. This transistor protects the input gate in the case where excessive voltage is applied between the input and the power source.

Title: Excitation method in solid-state laser
Inventor: MORIO KOICHI
IPC: H01S3/092
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To reduce the change in thermd lens effect and to improve the life of an excitation lamp by giving the lamp light quantity that is lower than a threshold, where laser beams are outputted when no laser beams are outputted. SOLUTION: Laser beams are outputted by exiting a laser medium with an excitation lamp. The light quantity of the excitation lamp that is lower than a threshold, where laser beams are outputted is given when no laser beams are outputted. When either large or small amount of laser beams is outputted, the light quantity of the excitation lamp when no laser beams are outputted is changed at a level that does not exceed the threshold, when the output of laser beams is large and small. Also, the amount of change is controlled so that the average in the light quantity of the excitation lamp per unit time becomes always constant. By reducing the change in a refractive index due to heat change, the change thermd lens effect is reduced. At the same time, by constantly heating a cathode, the life of the excitation lamp is improved.

Title: Steering torque detector
Inventor: NAKAMURA KYOICHI
IPC: G01L5/22
Filed: 1986-10-27
Abstract: PURPOSE:To eliminate an output error due to the core shift between the first and second revolving members, by providing both members to the connection part of a drive shaft and the elastic shaft of a steering shaft. CONSTITUTION:When a handle is operated, force is transmitted to a wheel steering mechanism through a steering shaft, an elastic shaft 3 and a drive shaft to generate twist displacement in the elastic shaft 3. By this mechanism, relative displacement is generated between the projections 6a, 6b, 7a, 7b of projection members 6, 7 and the opposed members 9a, 9b, 10a, 10b of detection members 9, 10, and minute gaps A-D change. When core shift is present between the first revolving member 5 and the second revolving member, the gaps A-D change so that not only the gaps A, C but also the gaps B, D opposed to each other so as to hold the elastic shaft 3 therebetween increase and decrease by the same interval. Since the synthetic signal of an operation circuit is outputted and the induced voltage of a detection coil 12a and that of a detection coil 12b are differentially operated in this state, said induced voltages due to core shift are negated and an output signal free from an output error due to the core shift between the first and second revolving members can be obtained.

Title: Gloves and their production
Inventor: MATSUURA AI
IPC: A41D19/00
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To obtain gloves of acrylic resin having tensile properties equal to or higher than those of gloves made of natural rubber or a vinyl chloride resin and excellent tear strength by forming an acrylic resin emulsion containing an acrylic staple into a film. SOLUTION: Molds of gloves are immersed in an acrylic resin emulsion containing at least an acrylic staple and coating films composed of the resin emulsion are formed on the surfaces of the molds to give the objective gloves. The gloves can be obtained by a simple method by a conventional immersion process. Since a vinyl chloride resin is not contained in the coating films of the gloves, the gloves have no fear of evolution of dioxin and contaminate an environment in scrapping and incineration. A crosslinking agent such as zinc flower, melamine resin, epoxy resin, etc., useful for processing a polymer may be cited as the crosslinking agent. The amount of the crosslinking agent compounded is preferably 1-10 pts.wt., especially 1-5 pts.wt. based on 100 pts.wt. of resin solid of the acrylic resin emulsion.

Title: Parts orderly feeder
Inventor: INOUE TAKUMI
IPC: B65G47/14
Filed: 1989-09-30
Abstract: PURPOSE:To realize the high speed orderly feeding of a short shaft bolt at a rotary feeder which transports a bolt in suspension, by providing integrally along the upper edge portion of a bowl a circular arc shaped support member which extends toward a bowl diameter outer direction and also inclines downward and which supports a bolt shaft portion. CONSTITUTION:When a bolt (m) is thrown onto a circular plate 35, it is moved in the uppermost portion 35a direction due to the centrifugal force of the rotating circular plate 35. And, it is inserted into a space between the upper edge portion of a bowl 33 and the lower edge of a bolt suspension member 48, and moved together with the rotation of the bowl 33. At this time, the shaft portion lof the bolt (m) is mounted on a support member 50, and receives the force of transport. Accordingly, as the shaft portion is brought into a surface contact with the support member 50 rotating together with the bowl 33, the bolt is transported at a speed approximately equal to that of the bowl 33. As a result, a bolt, even if it has a short shaft portion, can be fed surely in suspension at a high speed.

Abstract: PURPOSE: To reliably cutting remove chips without entangling them with each other by arranging at least a single opening part to form a passage in a tank- shaped vessel, in an edge part on the side facing to a side wall of an upper surface in a single cover element. CONSTITUTION: A reciprocating unit is covered with a cover, and the cover is composed of plural elements 21 to 25 slidingly movable in a telescope type in a mutually superposed condition. The element 21 closest to a workpiece table is rigidly joined to the table, and the smallest element 25 is joined to a side wall 40 vertically extending to the X axis. An opening part 39 is arranged on an upper surface of the element 25. A drawing shows a condition just before the respective elements 21 to 24 reach a left side tail end position. In this case, since a lip seal 53 of the second small element 24 already reaches a range of the opening part 39, cutting chips 60 and cutting oil 61 scraped off by lip seals 50 to 53 fall in a tank-shaped vessel 41 by passing through the opening part 39.  Therefore, the cutting chips 60 are avoided in forming an entangled lump in this side range of the side wall 40.
