Title: Oil injecting method for fluid joint
Inventor: BETSUSHIYO NORIAKI
IPC: B67D7/02
Filed: 1987-08-06
Abstract: PURPOSE:To provide oil injection with severe volume fraction containing a certain amount of air which serves selection of torque characteristics by adjusting the amount of oil injection in accordance with the capacity dispersion of the space part of a liquid chamber. CONSTITUTION:Silicon oil in a main tank 51 is supplied to a pressurization tank 55 by a pump 53 via a one-way valve 63, and passed through a flow meter 76 to be injected into a fluid chamber of a fluid joint 1 from a solenoid valve 57. A piston 67 of this pressurization tank 55 is sunk slowly by the compressed air sent from an air compressor 71 to permit the oil to flow out while it is held with low pressure and at low speed. Here an air volume tester 85 emits the volume difference between the reference space capacity of fluid chamber of the joint 1 and the space capacity to be injected in the form of a differential pressure signal. A controller 77 calculates and corrects the amount to be injected, gives a signal to the above-mentioned solenoid valve 57, and controls timing of valve opening and closing. Accordingly the oil flows in with low pressure and at low speed while retaining the strata state, wherein air bite can be suppressed effectively and the desired amount be poured in with good precision and in a short time.

Title: Developing device
Inventor: INOUE TAKAHIRO
IPC: G03G15/08
Filed: 1982-11-10
Abstract: PURPOSE:To develope one component with non-magnetic toner by vibrating the point edge part of an elastic brade by the rotation of a developing roller at a high speed and by frictionally contacting toner each other and the toner with the developing roller and the elastic brade to charge the toner with triboelectricity. CONSTITUTION:When the developing roller 14 is rotated by a driving source in the same arrow direction as an image carrier 1, the edge part 15a of the brade 15 is wound into the rotational direction of the developing roller 14 or rewound repeatedly at an extremely rapid cycle to be vibrated microscopically. Even if the toner 10 is slightly solidified, the solidification is loosened and ground by said vibration. At that time, the toner 10 is frictionally charged with the elastic brade 15 or the developing roller 14, so that the toner 10 is adsorbed and adhered to the charge of an electrostatic latent image on the surface of the image carrier 1 to attain development. Even if the toner is fed unevenly, the feeding is averaged at the abutted part between the developing roller 14 and the brade 15 and the picture is prevented from uneven density.

Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To eliminate the offset of a signal caused by an offset of an optical axis by moving an incident position of reflected light on a photodetector in interlocking with movement of an objective lens. SOLUTION: Actuators 12 and 13 for the objective lens(OL) 6 and the photodetector(PD) 8 respectively are connected in series, and a moving amt. of the PD 8 is made proportional to a moving amt. of the OL 6. Then, the OL 6 is moved by a prescribed amt., and at this point, a variable resistor 14 is adjusted to a value not to generate the offset of a tracking error signal. Consequently, the adjustment can easily be performed not to generate the offset of the tracking error signal of the PD 8 in whatever OL moving position. Then, when a inclination takes place between a recording medium 10 and the OL 6, the PD 8 is moved in the direction of canceling an offset.

Abstract: PURPOSE:To reduce the number of heat exchangers, simplify a structure of a cooling and heating device and facilitate a changing-over of a cooling and a heating operation by a method wherein an evaporator is provided with a flow path for a circulating thermal medium contacting with an evaporating surface of liquid coolant, and a flow path of coolant vapor connected to a separator and adjoining to the flow path of the circulating thermal medium through a thermal conducting surface. CONSTITUTION:A condensor 6 is provided with an evaporating chamber 40 connected to a liquid coolant flow path having a liquid coolant pump 10 installed therein. It has an evaporator 7 installed within this evaporation chamber 40, in which its inner pipe may form a coolant vapor flow path into which the coolant vapor may flow and its outer pipe has a thermal medium flowed therein and it is comprised of a double-pipe type heat exchanger forming a circulating thermal medium flow path for evaporating the coolant. During heating operation, the double-pipe type heat exchanger 7 may act as a coolant heater and in turn in case of cooling, it may act as an evaporator, so that it is possible to reduce the number of heat exchangers. Further, since the pipe having the thermal medium stored therein is not installed in the separator 2, the thermal medium is exposed to a high temperature during a cooling operation and no boiling may occur. In addition, during both cooling operation and heating operation, the flow path for the circulating thermal medium is the same and a changing-over of the flow path is not required, so that a three-way valve having a large diameter is not needed.

Title: Production of aluminum oxide needle crystal
Inventor: HAYASHI KATSURA
IPC: C30B29/62
Filed: 1989-07-31
Abstract: PURPOSE:To industrially stably obtain highly purified aluminum oxide needle crystal with simple treatment by mixing organic polymer to specific aluminum borate acicular crystal and subjecting to heat treatment at a fixed temperature. CONSTITUTION:An organic polymer is added to aluminum borate acicular crystal having >=1 average aspect ratio and mixed, then subjected to heat treatment at 800-1500 deg.C to afford the aimed aluminum oxide needle crystal. Besides, removing of boron becomes incomplete and aluminum oxide is not generated at a temperature below 800 deg.C of the heat treatment. On the other hand, although aluminum oxide needle crystal is generated at a temperature above 1500 deg.C of the heat treatment, aggregation of crystal is apt to be generated and handling of the crystal becomes difficult in using as a raw material. Furthermore, removing of boron is further accelerated by existence of carbon in said heat treatment.
