Title: Non-high-water flowmeter
Inventor: HARUYAMA SHUICHI
IPC: G01F1/32
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To measure a flow rate by using a vortex flowmeter by making use of a Karman vortex street phenomenon generated by arranging a vortex generating body in which a pressure sensor is installed integrally inside a fluid flowing in a conduit in a non-high-water state. SOLUTION: A fluid 20 flows inside a conduit 10 in a non-high-water state. The water level of the fluid 20 is found by a DC component obtained from one sensor, e.g. a sensor 41, at the lowermost stage, out of pressure sensors installed respectively at constant intervals on both side faces of a vortex generating body 30. On the other hand, a Karman vortex street is generated in a flow at the rear part of the vortex generating body 30, and the frequency of the Karman vortex street is proportional to the flow velocity of the fluid 20. The frequency of the Karman vortex street is detected by, e.g. one pair of sensors at the uppermost stage at a water level or higher, and the frequency of its AC component is adopted as the representative value of the flow velicity.  The DC component and the AC frequency component which are obtained are multiplied by a multiplication means, and a signal corresponding to the flow rate is obtained. When the signal is measured, a non-high-water flow rate can be found.

Title: Fuel injection valve
Inventor: SATO YASUO
IPC: F02M61/16
Filed: 1985-01-16
Abstract: PURPOSE:To mix fuel with air so sufficient enough and improve the output of engine power, by weakening an extent of spraying penetration with the fuel whirled in time of low engine speed, while accelerating its mixture with air in a way of wide-range injection, and checking the whirl in time of high speed for strengthening the spraying penetration. CONSTITUTION:In time of low engine speed, pressure in fuel is low whereby the fuel led into the inside of a passage 18 flows into a pressure receiving chamber 21 by way of passages 19 and 20. In addition, the fuel is filled up in a passage 22, a swirl chamber 24 and also an interconnecting passage 26 of a distance piece plus a passage 27. However, a check ball 28 being energized by a spring 29 keeps the passage 27 closed intact so that all the fuel flows into the pressure receiving chamber 21 from these passages 19 and 20, making a needle 6 go up. If so, the fuel is whirled by a spiral groove 23 installed in a first partition part 8 flows in the swirl chamber 24, then passes through a seat part 13, thus it is spouted out of a nozzle 12. Therefore, the fuel is sprayed at a wide angle and well mixed with an air in a combustion chamber with weak spraying penetration and thus ignited in good conditions.

Title: Ice making method for clear ice
Inventor: OHASHI YOSHINORI
IPC: F25C1/18
Filed: 1988-01-12
Abstract: PURPOSE:To produce clear ice in a short ice making time with high efficiency, by a method wherein a heating amount of a heating means positioned facing a cooling means is controlled according to a cooling amount of the cooling means for an ice making pan, and a freezing speed is maintained in a specified range. CONSTITUTION:When a thermostat 14 is in an ON-state, a first heater 18 is energized through the one contact of an ice making switch 20, through sufficient heating of a heating plate 10 by means of a high heat generating capacity, a cooling amount is suppressed, and a freezing speed is prevented from increasing. When the thermostat is in an OFF-state, a freezing speed is prevented from reducing to a low value more than necessary. In this way, control is made so that a wide change in a freezing speed is not produced when the thermostat 14 is both in an ON-state and in an OFF-state, and the freezing speed is stabilized in a range of approximate 2-3mm/hr. The progressing speed on a freezing surface of ice is decreased to a value lower than a speed at which a gas component dissolved in water is diffused upward, and under-water dissolution concentration of a gas component in the vicinity of a frozen surface is diluted to decrease the number of air bubbles producing times.

Title: Channel sharing system
Inventor: YOMO YOSHIAKI
Filed: 1988-01-14
Abstract: PURPOSE:To set an optimum radio line without assignment control of a radio line in a terminal call setting procedure by allowing a network terminator or a line controller to monitor a signal pattern and assigning an individual channel automatically. CONSTITUTION:When subscriber terminal equipment 1 sends a call setting signal, a signal line monitor circuit 5 of a network terminator 3 monitors a signal length, and applies an individual channel assignment request to an individual channel control circuit 7 and gives a command not sending a received signal to a subscriber signal transmission reception circuit 8 when the signal has a longer signal length more than the preset monitor signal length. The individual channel control circuit 7 sends an individual channel assignment request signal to an exchange station. The exchange station finds out an idle channel among individual channel groups and informs the channel number to the network terminator 3 in an opposite path. When the individual channel control circuit 7 receives the signal, the circuit 7 sends a signal stored in a signal buffer memory 6 through the informed individual channel.
