Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To safely store the material easy to be affected by the air and perform the work by providing an inlet of helium gas and an outlet to replace the air with the helium gas from an upper part in a space as the helium gas flows in and discharge the air from a lower part in the closed space, and providing a treatment space of the helium gas atmosphere in the space. SOLUTION: A treatment chamber in which the treatment space is a structure comprises side walls in the periphery and a ceiling in a closed manner, the helium flowing in from an inlet 2 is stored in an upper part of the treatment chamber as a helium layer HE while the air is pressed downward to form an air layer A. When helium gas successively flows in, the helium layer HE is increased in thickness and the air forming the air layer A is discharged out of the treatment chamber from an outlet 1. Finally, the air layer A is completely replaced with the helium layer HE, and helium is filled in the treatment chamber. Thus, the working efficiency of the work in which a large volume of dust is generated or the work which is not suitable in performing under the presence of dust, can be improved.

Title: Hand lift
Inventor: NOMAGUCHI YUTAKA
IPC: B62B3/06
Filed: 1994-12-28
Abstract: PURPOSE: To prevent sliding resistance from arising at an oil seal in the direction of rotation so as to make a handle controllable with a light force by causing an inner cylinder to be rotated integral with an outer cylinder when the handle is turned. CONSTITUTION: This hand lift which conveys cargo by slightly lifting it from a floor face lifts its main body 30 together with the cargo by raising an inner cylinder 1 by means of hydraulic pressure produced by driving a manually- operated hydraulic pump 33. The hand lift is steered by turning a handle 32 to the right and left for the rotation of an outer cylinder 2. In this case, the greater the weight of the cargo, the higher the pressure of pressure oil in a pressure chamber 4 and the broader the area over which an oil seal 3 makes contact with the inner cylinder 1. Since the inner cylinder 1 is supported via a thrust bearing 8, when the handle 32 is turned the inner cylinder 1 is rotated integral with the outer cylinder 2 and so sliding resistance does not arise at the oil seal 3.

Filed: 1993-12-24
Abstract: PURPOSE:To prevent generation of static electricity even if plastic is used for a cartridge and press plate by incorporating a material to lower specific surface resistance to a specific value or below in the resin material of a case. CONSTITUTION:The cartridge 200 for photographic films, of which the case is formed of the resin material, and the press plate 302 are formed of the resin material. This resin material contains the material to lower the specific surface resistance to <=10<12>OMEGA. This cartridge 200 for photographic films and this camera 301 are constituted by using a conductive material or an antistatic agent for this material. The film 6 receives contact friction with the press plate 302 and electrostatic charges are accumulated thereon at the time when the film is fed and, therefore, the resin material of the press plat 302 is also required to be confined in the specific surface resistance to <=10<12>OMEGA like for the cartridge 200. As a result, the static electricity generated between the film 6 and the cartridge 200 or the static electricity generated between the film 6 and the press plate 302 are conducted to the grounding part of a control substrate 310 disposed in a camera body 301.

Abstract: PURPOSE:To obtain a smooth spectrum curve by averaging time area data by a time area averaging means by corresponding times, averaging time area averaged data by frequency areas, and obtaining time area averaged data with a high S/N. CONSTITUTION:Data corresponding to the same time based upon a trigger are stored in the same addresses of memory planes of a memory 14. The same addresses of the memory planes of the memory 14 are read out, a shifter 8 performs division for averaging, and the output of the shifter 8 is integrated by a cumulative adder 19. Thus, the time area data are averaged and stored in a memory 21. The respective time area averaged data are converted by, for example, a fourier transforming means 22 into data on frequency areas. The frequency area data have corresponding frequency components averaged by the frequency area averaging means 23. Therefore, the time area averaged data with the high S/N ratio is obtained and the smooth spectrum curve is obtained.

Title: Prepreg manufacturing method
Inventor: KACHI YOSHIYUKI
IPC: B23K26/364
Filed: 1999-11-18
Abstract: PROBLEM TO BE SOLVED: To establish a prepreg cutting method capable of preventing generation of cutting chips without applying any processing such as heating to that part of prepreg other than the place to be cut. SOLUTION: The perpreg formed by impregnating a base material with a resin and left semi-hardening is to be cut into the specified dimension, when the surface of the prepreg is irradiated with a laser beam so that the resin of the irradiated portion is softened while the laser beam irradiating position is shifted, and the softened resin part is cut by a cutter blade. Because the cutter blade cuts the prepreg portion where the resin has softened, no resin will scatter as chips.

Abstract: PURPOSE: To enhance accuracy in the measurement of distance by emitting light only from a shielded light emitting element out of two light emitting elements and generating a correction signal thereby canceling the noise component generated from the light emitting element through a simple arrangement. CONSTITUTION: An emission trigger signal generation circuit 2 delivers a timing signal from a clock signal generation circuit 1, as a trigger signal, to a drive circuit 3' thus driving a light emission element 5 to emit light.
