Title: Fuel supplying device for lpg internal-conbustion engine
Inventor: MAKINO MOTOHIRO
IPC: F02M21/02
Filed: 1983-10-25
Abstract: PURPOSE:To prevent deviation of air/fuel ratio after releasing fuel interception and contrive a good idling operation by a method wherein a solenoid valve, interposed in a vacuum circuit, is opened for a predetermined period of time simultaneously with the releasing of the fuel interception during the idling operation after releasing the interception of fuel. CONSTITUTION:When the operation of the engine is shifted into the idle operation, the suction vacuum at the downstream of the throttle valve 15 becomes small, therefore, a vacuum control valve 16 is closed and a fuel intercepting valve 11 is opened to open a fuel path 10 since the vacuum in a control vacuum path 23 returns to an atmospheric pressure. At this time, the vacuum switch 46 is switched from ON to OFF, therefore, a control circuit 45 decides by the fuel intercept releasing decision circuit 47 thereof that the interception of the fuel is released and opens the solenoid valve 44 for a predetermined period of time. As a result, the vacuum path 40 is opened, the secondary chamber 7 of a vaporizer 3 is communicated with the suction path 14 at the downstream of the throttle valve 15 and the pressure of the secondary chamber becomes vacuum, therefore, the secondary diaphragm 9 returns to the normal condition thereof immediately. According to this method, the desired object may be achieved.

Abstract: PURPOSE:To obtain the simulation device for the traffic line of visitors which exactly predicts the residence state of the visitors. CONSTITUTION:The arrangement of plural facilities and paths and the entrance time and number of visitors are inputted, and facilities that the visitors are expected to move to are determined; while the respective visitors are considered to move in the site to the determined target facilities and utilize the facilities, the transition of the density of the visitors at respective places in the site is predicted.

Title: Production of oxide superconducting material
Inventor: SUZUKI TAKAAKI
IPC: C04B35/45
Filed: 1987-08-12
Abstract: PURPOSE:To obtain a superconducting material having high density, by hot- pressing oxide superconductor powder under specific temperature and pressure condition. CONSTITUTION:The objective superconducting material can be produced by hot-pressing oxide superconductor powder at 600-1,000 deg.C under 20MPa and, as necessary, post-treating at 800-1,000 deg.C. In the conventional process for the production of oxide superconducting material, a sintered material is produced by baking mixed powder twice or more. Accordingly, the reaction of powder takes place and gas is generated to fail the production of a dense sintered material. Contrary to the above, a mixed powder is directly hot-pressed in the present process, the reaction gas generates during the heating stage and the material is pressed after the generation of gas to form a dense sintered material. A calcination step can be omitted in the present process and the product has high density and excellent mechanical strength owing to the hot- pressing step.

Filed: 1989-08-01
Abstract: PURPOSE:To prevent fluctuation and unevenness of thickness of a second conductive type semiconductor region and to suppress defect by patterning a third insulation film by chemical etching for patterning and by exposing a second conductive type semiconductor region. CONSTITUTION:A silicon dioxide film 16 as a third insulation film is chemically etched by a buffered fluoric acid. In this case, since nitriding silicon films 17a and 17b are not etched by the buffered fluoric acid, silicon dioxide films 16a and 16b which are covered with the nitriding silicon films 17a and 17b remain. Etching of the silicon dioxide film 16 in this process is a chemical etching and has a great selectivity and is superb in uniformity so that it is possible to eliminate the silicon dioxide film 16 fully without actually etching a P-type base region 15. Also, almost no defect is induced into the P-type base region 15.

Title: Method and device for classification of fine granule
Inventor: AOKI ICHIROU
IPC: B03B5/62
Filed: 1982-11-15
Abstract: PURPOSE:To enable efficient classification of fine particles having a low settling velocity in a short time and a large amt. with good accuracy in a gravity field by making a rotating speed variable, changing the range where the fine particles locate in a small diameter tube and classifying the particles by making use of laminar flow. CONSTITUTION:Extremely gentle rotation at which the peripheral centrifugal force of a small diameter tube 1 placed in a gravity field is <=1/10 of gravity is given to the tube 1 to force the fine particles in the liquid filled in the tube 1 to draw a specified track resembling circular shape in the state eccentric with the tube 1 according to the respective particle sizes and to generate laminar flow in the liquid, so that the fine particles drawing the specified track are moved in the tube 1 at different speeds effected by the laminar flow. The rotating speed of the tube 1 is then changed to change the tracks to be drawn respectively by the fine particles and to reverse the direction of the laminar flow, whereby the fine particles having different particle sizes are distributed and classified equally to the right and left. The fine particles having a low settling velocity are thus efficiently classified in a short time and a large amt. with good accuracy in the gravity field.

Filed: 1992-07-28
Abstract: PURPOSE:To deliver outlet air to a circumferential living area and contrive the improvement of a temperature distribution in a room space, in an air conditioning apparatus which sends air-conditioning air from the side of a ceiling. CONSTITUTION:A flap 9 for regulating the direction of air sent by a ventilating fan 6 is provided and the position thereof is fluctuated by a flap motor 10 periodically along horizontal direction from vertically lower side of the fan 6. The direction of airflow is detected by a directional position of airflow detecting means 20 while the flow rate of air of the ventilating fan 6 is increased by an air flow rate control means 51 when the direction of airflow is moved from the vertically downward direction toward horizontal direction. According to this method, air speed in horizontal direction is increased to deliver outlet air effectively to a living area at the circumferential parts in a room against the effect of convection upon either cooling operation or heating operation whereby a temperature distribution in a room space is improved. When the title controller is constituted so that the fluctuation range of the direction of airflow can be set arbitrarily, the temperature distribution can be improved further.
