Title: Hermetic compressor
Inventor: SUGIMOTO SHUHEI
IPC: F04B39/00
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To ensure an oil separation and noise reduction in a hermetic- compressor muffler. SOLUTION: This hermetic compressor comprises a partition plate 17 partitioning a space inside a muffler 16 into inner and outer spaces, an oil separation passage formed in the partition plate 17 so as to connect the inner space and the outer space inside the muffler 16, a muffler inlet 19 formed in the inner space inside the muffler 16, and a muffler outlet 20 connecting the inner space inside the muffler 16 to a cylinder 15. In this case, cold gas that flows into the muffler 16 forms a flow along the partition plate 17 and oil whose relative density is larger than that of the cold gas is stored in the outer space outside the partition plate 17 via the oil separation passage by centrifugal force. Accordingly, the amount of the oil is kept appropriate so that the performance stabilizes, and thus the high reliability is provided.  Also, by the oil separation passage attenuating a pressure pulse, a noise thereof can be reduced.

Title: Multilayer molded product and its manufacture
Inventor: KOBAYASHI YOSHITAKA
IPC: B29K101/12
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To eliminate a feel of a bottom arrival without impairing cushionability even by using a skin material having a foaming layer by using the material having an at least open cell type foaming layer and a closed cell type foaming layer and adhesively integrating so that the open cell type layer becomes a front surface side of a molded product. SOLUTION: A skin material 1 is obtained by laminating a skin layer 2, an open cell type foaming layer 3 and a closed cell type foaming layer 4 with an adhesive or heat fusion bonding. In this case, the layer 3 is laminated to the layer 2 side from the layer 4. The material 1 is obtained by adhesively integrating with a base material 7 made of a thermoplastic resin. As a result, a heat and a pressure of molten resin when molded are shut off by the layer 4. Thus, the heat and the pressure are scarcely applied to the layer 3 to prevent collapse of the layer 3, and the multilayer molded product having no feel of bottom arrival is obtained by the layer 4.

Title: Pressure sensing type variable throttle valve device
Inventor: TEZUKA TAKAHIRO
IPC: F16K17/34
Filed: 1989-04-28
Abstract: PURPOSE:To simplify a processing operation and suppress an increase of a cost by providing a slight throttle part between a deformable elastic body and rod piercing therethrough, communicating chambers on both sides of the elastic body with each other through the throttle part, and deforming the elastic body at the time of pressure application. CONSTITUTION:When a pressure in a pilot chamber 56 is increased, high pressure is applied wholly to an elastic body 55 to cause elastic deformation of the body 55. When the pressure at the side of the pilot chamber 56 is higher than a preset value, the elastic body 55 is deformed to interrupt the communication of the pilot chamber 56 with a return chamber 57. When the pressure in the pilot chamber 56 is a preset value or lower, the elastic body 55 is not deformed so that the pilot chamber 56 is communicated with the return chamber 57 through a throttle 62. Fluid at the side of the pilot chamber 56 is, therefore, returns to a tank through the throttle 62, the return chamber 57 and a tank passage 58. In this pressure sensing type valve device, processing operation is very simplified so that a rod 61 can be pierced through a through-hole 59 formed on the elastic body 55 alone.

Abstract: PROBLEM TO BE SOLVED: To surely amplify a nucleic acid by subjecting the part of a specific base sequence or the like to a PCR amplification using a primer having a sequence supplementary to said base sequence excluding at least one base in a specific region from the 3'-terminal and a DNA polymerase. SOLUTION: A group of fragments 35, 39 consisting of base sequence parts having a specific base sequence of a nucleic acid or specific fragments having the specific base sequence of a mixture of fragments of the nucleic acid are prepared by introducing an oligomer 30 having a known base sequence into DNA fragments.

IPC: H04N5/335
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To obtain a cover glass for solid-stage image sensing element which has a reflection-reducing film little in radiation emitted therefrom and hardly peeling or breaking by forming a film structure composed of four or more alternately laminated layers made of titanium oxide and silicon oxide for this reflection-reducing film.

Little α ray radiation of each cover glass is emitted and no peel of the film is found. Thus the radiation emitted from the reflection-reducing films of the cover glass for the solid-stage image sensing device is in a small quantity and the thermal expansion coefficient of these films is approximated to that of the glass substrate and hence the peeling or breaking of these films are prevented.

Title: Method and system for correcting mask pattern and mask for exposure using them and semiconductor device
Inventor: KUJI TATSUAKI
IPC: G03F1/70
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To solve a difference in the effect of reflection by an underlayer material and a difference in size caused by the depth and the taper angle of etching at the same time, by providing a correction means arranged near a light source and capable of simply correcting a pattern on an exposing mask with high accuracy according to the underlayer material. SOLUTION: A gate electrode is formed on the device region of a silicon substrate and two contact holes are formed at the gate electrode and at a device region through an interlayer film. Since the reflection of light used for exposure is larger in the gate electrode made of Wsi than in the device region made of Si, the amount of exposing light absorbed by a resist film used in a lithography process of the contact hole becomes large, and to correct this, the side of a square pattern 2 on the mask is smaller than that of a square pattern 3. When the contact hole is formed, a difference in the amount of exposing light absorbed by the resist film which is caused by the difference between underlayer materials can be corrected by the size of the mask pattern for exposure in this manner.
