Title: Casting material for nuclear power plant
Inventor: HIMENO YOSHIAKI
IPC: C04B35/66
Filed: 1988-06-24
Abstract: PURPOSE:To form a casting material having no reactivity to high temperature sodium and being excellent as nuclear power plant use by setting the addition quantity of alumina cement in a castable refractory to specific weight %. CONSTITUTION:A casting material is kneaded sufficiently by adding water of about 5%, and applied by about 30mm thickness to the upper face of concrete being a structural material of a high speed breeder reactor by a conventional method. As for this casting material, crystal water and the moisture quantity after it has been applied and has been dried naturally are small, therefore, even if metallic natrium of a high temperature leaks, the moisture emission quantity is very small. Also, even if sodium oxide, sodium hydroxide, etc. are generated due to combustion of sodium, silica in amorphous silicic acid responds to them, and sodium silicate is generated on the surface of the casting material which has been applied, therefore, it does not occur that they infiltrate into the inside.

IPC: F16F9/50
Filed: 1989-06-19
Abstract: PURPOSE:To improve damping force performance by communicating the oil chamber in a closed circuit in the inside of a piston rod with a tank-side oil chamber in the outside. CONSTITUTION:A piston rod 2 is made up of a hollow shaft, and an oil chamber 9 is formed in a hollow part which has been hermetically closed by a plug at the external end. In the outside of an outer shell 4, a tank T is arranged, and the tank T comprises a gas chamber 10 partitioned by a bellows and an oil chamber 9a, and the oil chamber 9 in the inside of the rod 2 is communicated with the oil chamber 9a of the tank T via a pipeline 9b, and oil is filled in them. The oil chamber 9 functions as a reservoir in an operating oil circuit for controlling the throttle opening in a damping valve mechanism 8, and a slight volumetric change in the oil chamber 9 during operation is absorbed by the expansion or contraction of the gas chamber 10 on the tank T side, so that the pressure inside the reservoir can be always maintained nearly at a constant pressure. Further, the volume of the oil chamber 9 is increased by communicating it with the oil chamber 9a on the tank T side, thus pressure variation can be reduced, and damping force performance can be improved.

Title: Recording disc reproducer
Inventor: KOBAYASHI KOUICHI
IPC: G11B17/04
Filed: 1977-12-27
Abstract: PURPOSE: To stabilize operation through simple operation by controlling the revolutions of a guide plate elevating motor and a turntable and the movement of a pickup arm at specified timings.  
     CONSTITUTION: When a play switch 22 is pushed where a magnetic disc is held inserted in the reproducer, the clock input having passed through OR 108 and inverter 109 causes the Q output of an FF 113 to invert from "0" to "1". When the output of a motor driving circuit 15 is applied to AND 116, a motor 28 starts and the arm of its revolving shaft detaches from a control switch 48, thereby turning the switch OFF. Next, when the disc is placed on a turntable, the swtich 48 goes ON to apply the clock input to the FF 113 and therefoer its Q output becomes "0", causing the motor 28 to stop. At the same time, the output of a differentiation circuit 103 becomes clock input which is then applied to an FF 114. The Q output thereof is then made "1" and is applied together with the -Q putput "1" of the FF 113 to a main motor 29 via AND 117 to start the turntable 29, hence stable reproduction is accomplished.

Title: Color cone
Inventor: HIRATA YOSHIAKI
IPC: E01F13/02
Filed: 1999-04-25
Abstract: PROBLEM TO BE SOLVED: To make a color cone hardly crack even when it is thrown and dropped in an overlapped state by providing a rib matched to the shape of the head part or the base part of the color cone on the edge inside or the base inside of the color cone. SOLUTION: A rib 11 matched to the outer shape of the head part 10 of the color cone 1 is provided on the edge inside of a color cone 1. Even when the color cone 1 is thrown and dropped in an overlapped state, it is hardly cracked because it receives a shock by the rib 11. Furthermore, when a space 12 is provided in the center in which the rib 11 intersects, further more hard to crack because the shock is received by widening the rib 11. When a rib 21 matched to the outer shape of a base part 20 is provided in the inside of the base part 20 of the color cone 1, similar effect can be obtained. In addition, when an uneven part is provided on the edges of the ribs 11, 21, the effect is further large.

Title: Freezing device
Inventor: INOTA KENICHI
IPC: F25B41/06
Filed: 1977-12-29
Abstract: PURPOSE: To increase freezing efficiency, by providing in a part of the coolant passage a throttle device made of heat-insulating material.  
     CONSTITUTION: High temperature gas compressed by compressor 1 is condensed into a high temperature liquid by condenser 2. The liquid passes connecting pipe 3 and reaches throttle 4, and as it passes metal pipe part 4a, heat-insulating pipe part 4b, and metal pipe part 4a, it expands and becomes of low temperature and low pressure. Then it enters evaporator 8 via connecting pipe 7. Here, it evaporates and becomes gas. The gas enters compressor 1, and the same precess is repeated. Since a part of the flow passage consists of heat-insulating pipe part 4b as shown above, there is no heat transfer by conduction in throttle 4 from the side of connecting pipe 3 to the side of connecting pipe 7. Consequently, compared with conventional devices, freezing efficiency is increased.

Title: Method of making side by side conjugate fiber with no crimp
Inventor: NAKAJIMA TAKAYOSHI
IPC: D01F8/06
Filed: 1978-12-20
Abstract: PURPOSE:A crystalline polypropylene and a high-density polyethylene, both of which have specific intrinsic viscosities respectively, are melt spun into side by side conjugate fibers and drawn, thus producing fine-denier fibers by simple processes with high stable operability and increasing the efficiency. CONSTITUTION:(A) A crystalline polypropylene of 1.45-2.10 intrinsic viscosity and (B) a high-density polyethylene of 0.85-1.10 intrinsic viscosity are melt spun with a usual spinning device so as to satisfy the equation VXD>5000 (V is take-up speed m/min; D is denier of taken-up undrawn yarns) into side by side conjugate yarns. The resulting undrawn yarns are drawn at a temperature over 90 deg.C and lower than that begins to cause the fusion between fibers at 3-5 draw ratio with a usual drawing device, thus producing the objective side by side conjugate fibers. The spinning temperatures are preferably 200-350 deg.C at the side of component A and 170-300 deg.C at component B. EFFECT:The products are substantially crimp-free and not splittable. They are suitably used to make dry or wet nonwoven fabrics.
