Title: Cylinder device for reciprocating compressor
Inventor: KIN SHIYUUKAN
IPC: F04B39/00
Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent lowering of compression efficiency caused by re-expansion of residual coolant by providing a piston of a cylinder device in a reciprocating compressor, which is formed by two piston members connected to each other in the axial direction in such a manner as a slide and an elastic member interposed between both piston members. SOLUTION: In a cylinder device of a reciprocating compressor, a piston 20 comprises piston members 21, 25, and a spring washer 45 is interposed between the end part surface of the piston member 21 and an opposite surface of a piston head part 29, thereby elastically energizing the piston members 21, 25 in the direction of separating from each other. At this time, if the pressure of the compressed coolant is smaller than the elastic force of the spring washer 45, the piston members 21, 25 are put in the separate state, so that the piston 20 holds the maximum length. That is, the gap capacity between an intake valve lead 3 and the end part of the piston member 25 is minimized so as to reduce re-expansion by residual coolant, whereby the compression efficiency of the compressor can be increased.

Filed: 1990-07-27
Abstract: PURPOSE:To make it possible to determine accurate particle size distribution by dispersing the same sample into two solvents having the different refractive indexes, measuring the angle distributions of the intensities of the scattered light beams from both solvents, and finding the refractive index of a particle. CONSTITUTION:A sample W is uniformly dispersed into a solvent. The sample W is made to flow into a cell 1 under this state. A laser beam having the specified cross section is emitted from an emitting optical system comprising a laser light source 2 and a beam expander 3. The scattered light beams from the sample W are outputted through semiconductor photosensors P1 - Pn of a ring detector 5 and a photosensor Ps for measuring the sideward scattered light. The particle size distribution is outputted from a computor 12 based on the various kinds of relative refractive idexes for the scattering angle thetaof each photosensor and the memories of the theoritical scattered-light intensities of various kinds of particle diameters D. Thus, the accurate particle size distribu tion can be determined.

IPC: A61K6/083
Filed: 1991-07-17
Abstract: PURPOSE:To improve impact absorbing ability, to disperse fitting force and impact force and to reduce hindrance on conversation or uttering by making parts which are brought into contact with fitting faces to be hollow at the left and right posterior teeth of the dental arch.

Title: Manufacture of multilayer film
Inventor: KIKUCHI SACHIKO
IPC: G03F1/58
Filed: 1990-07-31
Abstract: PURPOSE:To prevent change in film thickness with the passage of time when an X-ray irradiation operation or the like is executed by a method wherein the film thickness of a multilayer film is stabilized while it is irradiated in advance with X-rays, ultraviolet rays, an electron beam or an ion beam. CONSTITUTION:As the film thickness of a multilayer film 2, each Mo film is 50Angstrom  thick and each C film is 76Angstrom  thick in order to reflect X-rays having a wavelength of 67.6Angstrom  at an oblique incidence angle of 15 deg.C; the total thickness of one laminated body is 126Angstrom ; the number of layers is 25. This film-thickness ratio is produced by using an electron beam vapor deposition apparatus by taking into consideration that the film thickness of the C film is increased by 6% when it is irradiated with the X-rays. When the multilayer film is irradiated with the X-rays by syncroton radiation light at 2X10<4> A.sec, the film thickness of a C film 2a is increased to 80Angstrom , the sum (d) of the Mo film and the C film becomes 130 Angstrom  and satisfies Bragg's relationship of 2d sintheta=lambda attheta= 150 and lambda=67.5Angstrom . As a result, a specification is satisfied. Since an increase in the film thickness of the C film is finished at an irradiation amount of about 10<4>A sec, the multilayer film is sufficiently stable when it is irradiated with X-rays.

Title: Low-nox burner
Inventor: WANI SHIZUO
IPC: F23C99/00
Filed: 1990-07-31
Abstract: PURPOSE:To reduce the generation of NOx without interfering with the combustion efficiency and stabilize the combustion by forming the cross section of an air outlet formed between the inner side of the air cone and the air plate an in annular but not circular. CONSTITUTION:An air cone 2 has the form of an elliptical cylinder and an air plate 4 is circular in peripheral outline. Therefore, in the flaming regions on the side where the ellipse has a smaller diameter, in contrast to where the diameter is larger, the supply of air is less than the average and hence the fuel is somewhat in surplus, whereas, contrarily, the air is in surplus in the flaming regions on the sides with larger diameters. Therefore, downstream from the burner, the combustion produces a flame which is asymmetric with portions forming flaming regions oversupplied with fuel and the other portions, flaming regions oversupplied with air, that is, formation of a flame produced in part by concentrated combustion and in part by thin combustion. This decrease the average temperature of the flame and hence restrains the generation of NOx.

Abstract: PURPOSE:To highly accurately detect abnormal states such as flood or fire on the bottom part of or ceiling of a tank by means of simple constitution by fitting a shape changing jig for converting a change in temperature or humidity around an optical fiber into physical bending force to the optical fiber in response to the change to the optical fiber. CONSTITUTION:The shape changing jig 1 is fitted to the optical fiber. A light source for transmitting the prescribed quantity of light to the optical fiber is connected to one end of the optical fiber 2 and a light quantity measuring instrument for measuring the quantity of light transmitted to the optical fiber is connected to the other end. When the temperature is raised up to 50-60 deg.C, the jig 1 is deformed to a curved shape. When the deformation of the jig 1 is generated, the optical fiber 2 is forcedly bent and the quantity of light flowing into the optical fiber 2 is lost. Thus, the abnormal state such as flood or fire can be remotely sensed. A chemical reaction layer 6 generating a heat generating or heat absorbing reaction at the time of coming into contact with water may be arranged on the shape changing jig 1.
