Title: Manufacture of tough titanium-base sintered hard alloy
Inventor: TOBIOKA MASAAKI
IPC: B22F1/00
Filed: 1986-08-19
Abstract: PURPOSE:To obtain a tough titanium-base sintered hard alloy having hard dispersed grains, by preparing a perfect fine double carbonitride of titanium, molybdenum and/or tungsten, and tantalum and/or niobium, by adding a metal powder of Fe, etc., to the above, by mixing them, and then by subjecting the resulting powder mixture to press compacting and sintering. CONSTITUTION:A carbon powder is added to titanium oxide and tantalum oxide, which is heated at 1,400-2,500 deg.C in a nitrogen stream. Then WC powder is added to the resulting double carbonitride (Ti, Ta) (C, N) and they are mixed, which is heated to 1,400-2,500 deg.C in a nitrogen stream to be formed into a double carbonitride of titanium, tantalum, and W. Subsequently, a powder of one or more metals selected from Fe, Co, Ni, etc., is added as binding metal to the above by 3.0-40.0wt%. These powders are further mixed and then is subjected to press compacting and sintering. Besides the above, another method using TiO2 and Nb2O5 (niobium oxide) can be applied. In this way, the tough titanium-base hard sintered alloy having extremely fine hard dispersed grains can be obtained.

Title: Waste liquid treatment apparatus of test tube
Inventor: OSAWA YUKIO
IPC: G01N35/10
Filed: 1987-08-03
Abstract: PURPOSE:To simplify the title apparatus, by removing the waste liquid in a test tube by a natural flow-out system utilizing the flowability of the waste liquid. CONSTITUTION:A test tube rack 5 is set on a stage 3a and an elevator 3 is driven to bring the upper end port of a test tube 4 into contact with a receiving port. A solenoid valve is opened in this state to inject a washing solution in the test tube 4 from a washing solution storage chamber 17 through a nozzle. Next, when a turn head 2 is revolved by about 120 deg., for example, in a counterclockwise direction, the test tube 4 tilts along with a waste liquid receiving vessel 6 and the waste liquid in the test tube 4 flows out along with the washing solution to flow out to a waste liquid receiving chamber 8 through a waste liquid receiving chamber 7 and a precipitated reaction substance remains in the test tube 4. When the head 2 is rotated reversely in this state to be returned to the original position, the waste liquid in the receiving chamber 8 flows to a passage 12 through a discharge port 13 and further sent out to a waste liquid storage tank 16 through a discharge chamber 14. Thereafter, the elevator 3 is allowed to fall to take out the test tube 4 along with a rack 5. By this method, the apparatus can be simplified.

Filed: 1985-09-04
Abstract: PURPOSE:To convert the rotating energy of a rotary body into electric energy highly efficiently without any loss by a method wherein a friction heat generating mechanism provided with the rotary body in a part of a hollow chamber is provided, and a driven rotary mechanism rotated by receiving tthe viscosity effect of fluid is arranged at a place opposing to the rotary body, while the rotating energy of the driven rotary mechanism is converted into electric energy. CONSTITUTION:When a rotary body 2 rotates to suck and exhaust gas in a hollow chamber 1, reduced-pressure balanced condition is kept in the hollow chamber 1 and heat generating effect is caused by the operation of an evacuated friction heat- generating mechanism X, whereby temperature increases gradually to heat a space A in the hollow chamber 1. When the choking amount of a gas inflow amount choking means 16 variates ins a situation from 'close' or the case of zero amount inflow to 'open', the reduced-pressure balanced condition in the hollow chamber 1 varates in accordance therewith. The rotation of the rotary body 2 rotates the driven rotary mechanism 8 by the viscosity effect of the fluid simultaneously with the generation of the reduced-pressure balanced condition in the space A of the hollow chamber 1, while the rotating energy of the driven mechanism 8 is transmitted directly or indirectly to the power-generating mechanism 10 and is converted here into electric energy.

IPC: G09G3/36
Filed: 1987-08-04
Abstract: PURPOSE:To prevent the deterioration of a contrast ratio even in case of a liquid crystal matrix panel in which the number of scanning side electrodes exceeds the number of effective scanning lines of one field portion, by executing a driving method by which the number of times of selection per unit time of an arbitrary picture element is not decreased even if an interlace scan is executed.

SOLUTION: Refrigerant is fed to a double tube type ice scraping heat exchanger 2 to subcool saline water solution 9. When icemaking cool storage scraping is started, the solution is floated as crystal ice 8 at the upper part in a cool storage tank so that the intermediate part is sherbet-like and the lower part is chilled water. Thus, when it is continuously operated to icemake it, cool storage can be executed. Simultaneously, the ice 8 also used to hold low temperature as crushed ice. As a result, a brine cooler 1 is continuously operated through the daytime and night, used as crystal ice making special purpose cycle during the night and pausing time, chilled water is supplied via the ice 8 during the daytime operating.  The refrigerator can be reduced in size by the sum of the latent heat of fusion of the ice and the refrigerating cooling capacity, and energy conservation can be intended by using the midnight power service.
