Title: Butterfly valve
Inventor: KITSUTAKA YUTAKA
IPC: F16K1/52
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To adjust flow rate characteristics according to a valve opening by arranging a curved surface which has radius of curvature larger than that of an outer periphery of a valve body, is extended to an opening direction of the valve body, and decreased in its diameter from a longitudinal axis to the opening side, in the vicinity of circumferential both sides of an intersection of a horizontal line perpendicular to a center line on the inner surface of a valve box. SOLUTION: When a valve body 2 is turned clockwise from a closed position indicated by an actual line to a full-open position indicated by a virtual line, spacing between orbits or a curved surface 4 of an inner surface 1A of a valve box 1 and an outer side 2A of the valve body 2 is increased together with enlargement of a rotational angle of the valve body 2. A sectional area for passing fluid is enlarged and a flow rate is increase. When the valve body is turned counterclockwise, spacing between rotational orbits of the curved surface 4 of the inner surface 1A of the valve box 1 and the outer side 2A of the valve body 2 is decreased. The sectional area for passing fluid is reduced, and the flow rate is decreased or, even reduced to zero.  It is thus possible to vary relation between a rotational angle of the valve body, a fluid passing sectional area, and a flow rate according to curvature of the curved surface.

Title: Liquid fuel vaporizer
Inventor: OGINO TOSHIRO
IPC: F23D11/44
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To prevent the quantity of combustion from being decreased or abnormal combustion from being produced in short time because of the generation of tar even by using fuel containing a high boiling point component in the vaporizing part of a liquid fuel combustion device. SOLUTION: A liquid fuel vaporizer comprises an outer pipe 22 having a nozzle 27 at one end and a fuel supply port 28 at the other end, an exciting coil 26 wound on the outer peripheral side of the outer pipe 22, a porous body 23 provided in the outer pipe 22, a shaft body 24 with magnetic permeability higher than that of the outer pipe 22 and a space part 23a provided between the outer pipe 22 in the nozzle 27 side and the shaft body 24. Since the porous body 23 for absorbing a magnetic field is not provided in the space part 23a in the nozzle 27 side of the outer pipe 22, the temperature of the shaft body 24 is higher than that of other parts and a high boiling point component in fuel which cannot be vaporized in the porous body 23 can be vaporized in a downstream space part. Thus, the generation of tar due to imperfect vaporization can be effectively suppressed.

Title: Ultrasonic vibration type float polishing device
Inventor: IMANARI TORU
IPC: B24B37/00
Filed: 1984-09-14
Abstract: PURPOSE:To actively crush abrasive grains and sharply reduce a float polishing hour by mounting a device to cause a float polishing dish or a work to ultrasonically vibrate. CONSTITUTION:When a float polishing dish 5 immersed in processing liquid 12 is rotated round a shaft 9 through an external rotating body 6 by a motor 7, pressure opposite to the direction of gravity is caused by dynamic pressure effect on the groove of the float polishing dish 5. At this time, pressure lower than dynamic pressure is applied to a work 9 by means of a holder 10 to press the work 9 against the float polishing dish 5 as the work 9 is rotated with a ho older 10 by a motor 11. Thus the work 9 is polished owing to its collision with polishing material though getting out of contact with the float polishing dish 5. When the power source of a generator 1 is turned on, an ultrasonic signal is transmitted through a brush 3 to a piezoelectric transducer 2, and an ultrasonic vibration produced by the transducer 2 in circumferential direction is transmitted to free abrasive grains between the float polishing dish 5 and the work 9.

CONSTITUTION:The brightness information on the object is recorded at the time of the photographing, the brightness information is read out at the time of the photographic printing to classify scenes, and a printing exposure quantity is calculated for each photographic scene by using an arithmetic system such as a prepared arithmetic expression. Namely, a photometric value of the light of the object is controlled by a shutter mechanism 12 and sent as the brightness information to a bar code data generating circuit 23, and converted into bar code data, which is recorded on, for example, a film 18. The brightness of the bar code data is predicted by using the brightness information to accurately remove measurement points which are necessary for either the scene classification nor exposure control.

Title: Optical system controller of laser beam printer
Inventor: OOSAWA HIROSHI
IPC: G03G15/04
Filed: 1983-10-14
Abstract: PURPOSE:To prevent degradation of picture quality due to variance of temperature by detecting the temperature of a supporting body of a plastic lens provided in a laser beam optical system and controlling the temperature of the supporting body to a set temperature on the basis of the detected temperature by a heating/cooling means. CONSTITUTION:When the temperature of a collimation lens supporting body 20 is changed, the resistance value of a thermistor 2b is changed. This change of the resistance value is taken out as a change of voltage, and this voltage is compared with a set voltage Vr by an operational amplifier 15a; and when the output voltage of the amplifier 15a is positive, an NPN transistor TR15b is turned on, and a current is flowed to a Peltier element 2c to cool the supporting body 20. When the output voltage of the operational amplifier 15a is negative, a PNP TR15c is turned on, and therefore, the direction of the current flowed to the Peltier element 2c is inverted to heat the supporting body 20. Thus, since the collimation lens supporting body can be held at the set temperature, the refractive index of a collimation lens 2a is kept constant, and degradation of picture quality is prevented.

Abstract: PURPOSE:To perform data transfer between memories at a high speed without affecting a processor, and a system bus sides, by transferring data between the memories in a state where a memory bus is separated from the system bus by a gate circuit. CONSTITUTION:When a request to transfer the data of the memory 2a to the memory 2b is generated in the processor 1, the processor 1 impresses a start up signal on an inter-memory transfer part 7b in a memory control part 7, and also, transmits a transfer content.
