Title: Screen structure
Inventor: NAKANO YUZO
IPC: G03B21/58
Filed: 1991-08-01
Abstract: PURPOSE:To prevent a screen film holding rod from falling suddenly by moving upper and lower one-end sides of pipes, which are constituted in a pantograph shape, horizontally by a guide and controlling the horizontal movement by a spring. CONSTITUTION:One-end sides 13 of a pair of rectangular pipes 11 and 12 which are rotatable in a bent shape are fixed in position and rotatable and the other- end sides 14 are horizontally movable along the guide grooves 15a and 16a of slide rails 15 and 16 respectively. A spring 17 engages a groove 16 where the horizontal movement is possible and controls the motion of the pantograph type pipes 11 and 12 when they move down. When the screen is in use, the horizontal spring 17 operates to press up the screen film holding rod, so the required lifting force may be small. When the screen is stored, the force of the spring 17 operates in addition to the pressure of a gas spring 8 as the screen film holding rod is lowered below the intermediate point, so that the screen film holding rod is put in smooth motion without falling suddenly.

Filed: 1986-09-13
Abstract: PURPOSE:To eliminate gas accumulated in a gas storage of a cavity, control scatter of inner pressure distribution and reduce generation of cracks by retaining a clearance between a top force and a bottom force for a fixed period of time and then locking after stock solution is injected into a mold. CONSTITUTION:After stock solution is injected, a core 2 first reaches the limit of downward movement, and then a top force 3 comes down and is supported by a coil spring 5 to generate a clearance in a parting line 14. With said clerance left as it is, a clamp is clamped after a few seconds, and the top force 3 and a bottom force 4 are located and sealed completely. A spring 5 is preferably installed in a manner to leave a clearance of 5mm or more to 50mm or less in the parting line 14 on the clamp side 12. By said arrangement, air in the cavity is exhausted out the mold together with blowing gas to leave no gas in the gas storage, and generation of large and small cracks are reduced by minimizing scatter of inner pressure distribution.

Title: Production of titanium diboride
Inventor: HAMAMOTO HIROSHI
IPC: C01B35/04
Filed: 1987-08-31
Abstract: PURPOSE:To obtain high-purity and fine titanium diboride without the need of grinding process, by reaction between titanium nitride powder and boron powder under each specified monoxidative atmosphere and temperature. CONSTITUTION:The objective powder can be obtained by bringing titanium nitride powder and boron powder into contact with each other at 1,000-1,800 deg.C under a nonoxidative atmosphere except nitrogen gas one to perform reaction. In this production process, nitrogen is formed as a by-product, therefore, use of a nitrogen gas as an inert gas will hamper the reaction, and the nitrogen gas should thus be eliminated from nonoxidative atmospheres. Hydrogen gas etc. inert to the reaction feedstock can be used instead of inert gases; alternatively, depressurization is permitted to produce nonoxidative atmosphere. Removal of the nitrogen gas produced by the reaction under reduced pressure out of the reaction system will further enhance the reaction rate.
