Title: Read/write circuit for magnetic recording device
Inventor: FUKUDA MASARU
IPC: G11B20/00
Filed: 1993-03-08
Abstract: PURPOSE: To provide an R/W circuit where the output of an AGC is not shifted regardless of the irregular change of the output of an R/W amplifier in a transition period and the detection output is not delayed consequently. CONSTITUTION: This circuit is provided with a means which sets the output of an R/W amplifier 12 to the high impedance state only for a prescribed time after switching the operation of a magnetic recorder from write to read. The means consists of switches 20 and 22, which are connected to the output of the amplifier 12, and an output control circuit 24 which controls switching of these switches. The output control circuit 24 opens switches 20 and 22 only for a prescribed time after switching to read so that the irregular output of the amplifier 12 doesn't have an influence on the circuit in the succeeding stage.

Title: Liquid rectifier of liquid distributor for mass and/or heat exchange tower
Inventor: MAEDA YUTAKA
IPC: B01J19/32
Filed: 1994-03-17
Abstract: PURPOSE:To uniformize the flow rates from respective nozzles by constituting a liquid rectifier of a plurality of lower rectification plates arranged in parallel to a horizontal liquid flow direction so as to leave an interval and a plurality of upper rectification plates arranged in parallel to the direction crossing the lower rectification plates so as to leave an interval. CONSTITUTION:Upper and lower rectification plates 5, 4 are arranged so as to cross each other because a liquid stream is once allowed to flow down in a vertical direction as laminar flow by the upper rectification plates 5 and subsequently allowed to flow in a horizontal direction being the extending direction of a main pipe 2 as laminar flow by the lower rectification plates 4. When this rectifier is used in a liquid distributor, it is avoided that turblent flow is generated at the connection part of the vertical pipe 1 and main pipe 2 of the distributor and a liquid is uniformly distributed to respective distribution pipes 3 and respective nozzle orifices 6. Further, even when the flow down rate of the liquid changes and the head is fluctuated, the laminar flow in the extending direction of the main pipe 2 is stably formed and the liquid is uniformly distributed.

Title: Piezoelectric oscillation gyro
Inventor: FUDA YOSHIAKI
IPC: G01C19/5649
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric oscillation gyro including a piezoelectric oscillator of a unimorph structure of a simple structure capable of connecting the terminals of input/output without using lead wires. SOLUTION: A piezoelectric oscillator for a piezoelectric oscillation gyro of a unimorph structure is formed of a column-shaped bending oscillator in which a PZT- based piezoelectric ceramics rectangular plate 11 is crimped against and adhered to a nickel rectangular plate 12 and in which a pair of band-shaped surface electrodes 13 and 14 longitudinally parallelly divided into two are provided on a surface of the rectangular plate 11.  The piezoelectric oscillator generates both first bending oscillations by impressing A.C. voltage of the resonance frequency of bending oscillations between the electrodes 13 and 14 and the rectangular plate 12 and second bending oscillations which intersect the center axis of the bending oscillations and the first bending oscillations at right angles are generated by the Coriolis force at the time when the column-shaped bending oscillator is rotated about any axis in parallel with the longitudinal center axis of the rectangular plate 11. By this constitution, it is possible to detect output voltage from the band-shaped surface electrodes 13 and 14 on the basis of piezoelectric effects due to the second bending oscillations.

Abstract: PURPOSE:To cause AC signals to pass through without generating instant-aneous disconnections while maitaining a sufficient perfomance, by supplying the gate current during all the time when thyristors connected in anti-parallel are intended to be conductive. CONSTITUTION:Anti-parallel connceted thyristors 41 and 43 arranged between AC signal source 1 and load 2 have base terminals of first conduction-type equivalent transistors (Tr) connected commonly and have low equivalent resistances 42 and 44, which satisfy a desired dv/dt characteristic, connected in parallel to the base- emitter junction of two second conduction-type equivalent Tr respectively.

In case that thyristors have a negative or positive voltage at a conduction time, driving circuits 49 and 50 supply sufficient gate current Ig to thyristors by small input current Ii, so that thyristors can maintain the conduction state without instantaneous disconnection independently of the power-factor of load 2.

IPC: A23F5/10
Filed: 1986-03-06
Abstract: PURPOSE:Coffee beans are heated and pressurized in a twin screw extruder and ejected into normal pressure so that the useful components in coffee beans are made readily extractable in a shortened time. CONSTITUTION:Coffee beans are fed into a twin-screw extruder, transferred under heating and pressurizing, then extruded into the air under normal pressure. Thus, the air in the beans is allowed to burst to break the connective tissues of the beans into porous structure. The coffee beans may be previously roasted, but is is preferred that raw beans are fed into the extruder where they are roasted while heat-treated.

Title: Device for supplying fuel to engine
Inventor: OGINO RIYOUICHI
IPC: F02M1/12
Filed: 1980-04-10
Abstract: PURPOSE: To improve warming-up and travelling property in an engine using mixed fuel of alcohol and gasoline by controlling current amount to an electric heater for heating a bimetal for controlling the opening of a choke valve according to alcohol concentration.  
     CONSTITUTION: When an engine is under cold condition and a choke valve 2 is closed, the engine is started and then an electric heater 8 is energized by closing an ignition switch 14. A bimetal 6 heated by this heater 8 is deformed to open the choke valve 2 in response to the rise of the bimetal temperature. When alcohol concentration in mixed fuel detected by an alcohol concentration sensor 12 reaches high one above a set value, a control 13 changes over a switch circuit 17 to the resistance 16 side by a control circuit 18 to decrease the heating output (heating value) of the electric heater 8 by a set value corresponding to the size of resistance 16. Thus, the opening operation of the choke valve 2 is delayed to enrich air fuel ratio.

Title: Pressure roller for fixation
Inventor: MIHARA NAOHARU
IPC: G03G15/20
Filed: 1983-03-23
Abstract: PURPOSE:To increase the nip width of the whole rubber layer while maintaining proper hardness in a surface layer of fluororesin by covering a thick foamed body layer formed around a shaft material with the thin surface layer of fluororesin. CONSTITUTION:The outer circumference of the foamed body layer 3 of silicone rubber which is formed thickly is covered with the surface layer 1 of fluororesin which deforms freely in a thin cylinder shape. Therefore, if a pressure roller 5 contacts a heat roller 4 on specific nip pressure, it deforms easily and the surface layer 1 of fluororesin is thin, so the roller deforms freely to make the nip width W to the heat roller 4 relatively large, thereby extending to the time of contacting with toner. Further, the surface layer 1 of fluororesin has hardness relatively higher than that of the foamed body layer 3, so the necessary nip pressure to the toner is secured and excellent fixing performance is obtained.

Title: Alarm clock which releases vapor of awakening acceleration material
Inventor: SHIMIZU SHOTARO
IPC: G04B23/02
Filed: 1987-03-03
Abstract: PURPOSE:To permit sure and comfortable awakening at a set time in the sate of a light sleep by releasing the vapor of an awakening acceleration material in the prescribed time before the set alarm time and emitting alarm sounds at the set time following said release. CONSTITUTION:An aroma mechanism 3 functions to release the vapor of the awakening acceleration material. Stimulative and aromatic materials such as menthol, peppermint and cinnamon are known as the awakening acceleration material. An aroma is released from the mechanism 3 upon timing out of the preceding time to start the aroma in precedence to the setting of the sounding time and sounding set in an alarm time setting mechanism 4. A user is stimulated by the aroma and is thereby gradually lightened in the sleep. Swinging musics are produced from a sounding mechanism 2 in the prescribed time when the physical condition such as action level of the brain and the blood pressure is ready to get up. The user is thus capable of getting with a comfortable feel without having any resistance at all.
