Title: Machine for grading and washing salmon roe
Inventor: SATO ATSUSHI
IPC: A23L17/30
Filed: 1999-10-25
Abstract: PROBLEM TO BE SOLVED: To perfectly separate off defective salmon roe, foreign matters and so on from mature salmon roe. SOLUTION: This machine for grading and washing salmon roe is obtained by disposing at least one salmon-carrying plate 11 in which many slits 14 having widths not permitting the dropping of normal salmon roe are formed, elastically supporting a salmon roe-carrying section 7 downward inclined in the salmon roe-carrying direction on a frame 5, disposing a vibration means 16 in the salmon roe-carrying section 7, and disposing shower means 18 for spraying salt water above the salmon roe-carrying section 7. The salmon roe-carrying section 7 is vibrated with the vibration means 16, and simultaneously sprayed with the salt water by the use of the shower means 18, thus carrying the salmon roe with the flow of the salt water.  Thereby, the defective salmon roe and foreign matters are removed from the slits 14 of the salmon roe-carrying plate 11, and only the normal salmon roe is recovered at a normal position.

IPC: G04C3/14
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To efficiently arrange a mechanical part being constituted inside a timepiece, and to achieve miniaturization and thinness. SOLUTION: Since rotary weight 25 is also supported by a first race 3 as in a train wheel for a timepiece, only the first race 3 is screwed and fixed to a base plate 2, thus reducing a place for screwing.

Title: Image formation
Inventor: HIROSE MASAKI
IPC: B41J2/42
Filed: 1987-12-02
Abstract: PURPOSE:To facilitate processes and to eliminate the need for high energy by applying a magnetic field to fine powder which contains a superconductor on a base and floating fine powder except powder which is heated by utilizing Meissner effect. CONSTITUTION:Normal paper 2 is mounted on a base 1 and coloring fine powder 3 which contains the superconductor is dispersed uniformly thereupon. Then the fine powder 3 after being cooled and dispersed is heated selectively by a laser 4 above critical temperature To where the superconductor changes from a superconductive state to a normal state. Then a permanent magnet 5 is set behind the base 1 with the N pole (or S pole) up and the magnetic field is applied to the fine powder 3 vertically upward from below the base 1. The fine powder which contains the superconductor in the superconductive state floats against gravitation with the resiliency to the magnetic field based upon the Meissner effect and the superconductor 3 which is heated above the critical temperature is in the normal state, so the fine powder which contains it does not float. Consequently, an image is formed by the simple process and the operation is possible with small energy.

Title: Hydraulic transmission joint
Inventor: SUZUKI SATORU
IPC: F16D31/02
Filed: 1993-12-03
Abstract: PURPOSE:To prevent the generation of hammering noise between a cam and a plunger by using oil pressure in place of a return spring for pressing the plunger to the cam side in a hydraulic power transmission joint. CONSTITUTION:Oil pressure is supplied from a communicating groove 12 communicated with a cylinder hole 8 so that a return piston 11 is reciprocated in the cylinder hole 8 integrally with a plunger 5. At the time of supplying oil pressure, oil discharged from a plunger chamber 6 is collected into a high pressure chamber 18, and this oil pressure is reduced by a pressure reducing means 43. In this case, an orifice 23 is closed by a first relief means 28 at the specified pre-load to secure the lowest oil pressure. At the release time, a second relief means 33 is opened to eliminate the pressure of the communicating groove 12. Consequently, there is no load to push the plunger 5 back to the cam 2 side, so that the plunger 5 after a discharge stroke is put in the withdrawn state. Hammering noise caused by collisions between the cam and plunger is not therefore generated.

Each of these aimed products is useful as an intermediate for hexamethylenediamine, a raw material for nylon 66, or an intermediate for rust-proofing agent or rubber curing promoters. By this method, formation of propionitrile as a by-product is markedly suppressed, and the objective acrylonitrile dimers can be obtained together with a cyanoethyl ester, a coproduct easily convertible into acrylonitrile.

Abstract: PURPOSE:To measure the concentration of impurity in a highly doped P-type silicon crystal, and perform simply the concentration measurement at a high speed without making a sample thin, by applying the total reflection absorption method for infrared spectrum to a P-type silicon crystal. CONSTITUTION:A highly doped P-type silicon crystal 1 is subjected to hydrogen plasma treatment or hydrogen ion implantation at a temperature lower than or equal to 200 deg.C, and a P-type silicon crystal 2 is formed. A total reflection absorption method of infrared spectrum is applied to the crystal 2.

The ray repeats successively total reflection on the boundary surface between the upper and the lower crystals 2 and the medium crystal 4, and propagates in the crystal 4. Finally the ray enters a photo detector 7 arranged outside the crystal 4. Thereby, the measurement of impurity in the highly doped P-type silicon crystal is enabled, and the measurement of impurity with simple constitution and high sensitivity is performed without making a sample thin.
