Title: Production of silicon nitride powder
Inventor: KAMIYA SUMIO
IPC: C04B35/584
Filed: 1983-03-15
Abstract: PURPOSE:Metallic silicon is nitrided, crushed and heat-treated in an inert gas atmosphere to make the iron included in the product as an impurity harmless, thus enabling easy and inexpensive production of silicon nitride powder which is suitable for use as a starting substance of sintered materials. CONSTITUTION:Particles of silicon nitride resulting from nitriding of metallic silicon are crushed by means of a crusher such as an iron ball mill, then roasted by heating in an inert gas atmosphere such as N2, Ar, or He at 700-1,500 deg.C, preferably 1,000-1,200 deg.C to make the iron included in silicon nitride harmless in the form of iron siliconide. Further, they are subjected to crushing with a ball mill which has no danger of contamination with iron to crush the iron siliconide, thus giving fine particles of silicon nitride of uniform particle size suitable for use as a starting substance for high-quality sintered products, at low costs and in large amounts.

Title: Closing method for liquid flow passage and apparatus thereof
Inventor: MIYAJIMA HIDENOBU
IPC: F16K23/00
Filed: 1979-04-09
Abstract: PURPOSE: To improve liquid separation of the poured-out liquid by closing a liquid flow passage with a valve and forming negative pressure in the liquid flow passage close to the pouring-out port side from the valve by means of suction mechanism.  
     CONSTITUTION: If a pump 13 is driven and air is fed from a flow-passage 12, the liquid level is raised, and at the same time a portion of the air flows into the hollow part 8 from a branched passage 14, and a diaphragm 7 is pushed down against a spring 10. Accordingly, a valve rod 6 and a valve 5 connected with the siaphragm 7 are lowered, and the opening end 41 of the liquid flow passage 4 is opened, then the liquid having been pressed flows-out from the liquid flow passage 4. On the other hand, if the pump 13 is stopped, the diaphragm 7 is raised by the spring 10, so the liquid flow passage 4 is closed by the valve 5. However, the diaphragm 7 goes up further, so negative pressure is generated in the lower hollow chamber 81, and due to this negative pressure, the liquid left in the liquid flow passage 4 is sucked in, and liquid separation is improved.

Title: Control system of motor position
Inventor: TOYODA KENICHI
IPC: H02P29/00
Filed: 1983-03-15
Abstract: PURPOSE:To suppress the vibrations and to increase the stopping accuracy of a motor by setting high and low gains when the position error between the commanded shift degree and the rotational frequency of a motor is small and large respectively when said position error is multiplied by the set gain. CONSTITUTION:The rotational frequency of a motor 18 is detected by a pulse coder 19, and an error register 15b detects the error between the commanded shift degree and the detected shift degree. Then an output Er is sent to a multiplier 15d and a numerical control part. The numerical control part stores a gain which is reduced as the Er increases to a register 15c when the Er is larger than the limit value E0 and then stores a fixed and large gain when the Er is smaller than the value E0 respectively. The output Er is multiplied by the value of the register 15c through the multiplier 15d. This value of multiplication is converted into the voltage Vc by an analog switch 15e and an analog adder 16 and applied to control the drive of the motor 18.

Abstract: PROBLEM TO BE SOLVED: To protect an occupant within an automobile cabin by compressing a first capacity part by the first part of the body of the occupant, and pushing at least a part of expanding gas into a second capacity part. SOLUTION: A cushion 10 is arranged in an optional position within a cabin capable of providing air bag passive type constraint. The cushion has a substantially L-shape, and the leg part of L is formed of an extension part 20. The vertical part of L comprises a first capacity part 22 directly communicating with the extension part 20. The vertical part comprises a second capacity part 24 communicating with the first capacity part, and the first and second capacity parts are mutually partitioned along a boundary 26. At use, the first capacity part 22 is expanded with a large quantity of gas, but the second capacity part is not expanded. As the first capacity part is compressed by an occupant to damp the force of the cushion, the gas is pushed into the second capacity part to expand it. The occupant is compressed and protected by the second capacity part.  Thus, the occupant can be safety protected.
