IPC: F25B1/10
Filed: 1988-09-16
Abstract: PURPOSE:To stabilize the supply oil to the bearing of a compressor and reduce the amount of rise in oil by providing a pressure take-out port at the gas stor age section in the cylindrical section of an oil tank and connecting said pressure take-out port with the pressure take-out port provided at the intermediate pres sure section in a two-stage compressor casing by a capillary tube to bypass the gas that is staying in the oil tank. CONSTITUTION:With pressure take-out port provided at the cylindrical section of an oil tank 3 and a pressure take-out outlet at the intermediate pressure section of a two-stage compressor 1 connected by a capillary tube 9 the coolant gas that stays in the oil tank 3 is discharged into the two-stage compressor 1 by the pressure difference at both ports. With this arrangement the oil separat ed in an oil separator 2 becomes easy to drop to the inside of an oil tank 8. By the characteristics of the capillary tube the gas that stays in the upper section of the oil tank 3 is discharged and in the process of the rise of the oil level face it does not rise higher than the position of the pressure take-out port and it is possible to permit the existence of an arbitrary section where the gas can stay.

Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To suppress oil hammering generated at the time of switching high-low pressure oil by a high-low pressure switching valve in a two-pressure hydraulic circuit. SOLUTION: A high-low pressure switching valve 45 provided with a P-port communicating with a high pressure oil supply conduit, a T-port communicating with a low pressure oil supply conduit, and a B-port communicating with a conduit for supplying pressure oil to a hydraulic cylinder is formed in a two-pressure hydraulic circuit, and a main spool 55 in the valve 45 is moved to switch a high pressure line HPL for communicating the P-port to the B-port, and a low pressure line LPL for communicating the T-port to the B-port.  The first chamfer part 75 is formed at the shoulder of an end surface 69 on the low pressure line side of the valve part 57c of the main spool 55, the second chamfer part 77 is formed at the shoulder of an end surface 73 on the high pressure line side of the valve part 57c of the main spool 55 so that the low pressure line and high pressure line may communicate instantaneously with each other at the time of switching the high pressure line and the low pressure line.

Title: Image forming device
Inventor: NAWAMA JIYUNICHI
IPC: G03G15/14
Filed: 1993-09-16
Abstract: PURPOSE:To suppress the scattering of toner on an image by providing a means for removing a charge possessed by an image receiving paper on the downstream side of the carrying of the image receiving paper of a guiding/separating means. CONSTITUTION:The guiding/separating member 111 whose head part is in a smooth radiused shape without a corner part is provided. Moreover, a tip pointed electrode 112 grounded in the vicinity of the downstream side of the carrying of the image receiving paper of the guiding/separating member 111 is provided. Therefore, an electric field formed by the charge possessed by the image receiving paper 108 after being separated is concentrated on the pointed edge of the tip pointed electrode 112, so that an atmospheric discharge occurs between the image receiving paper 108 and the pointed edge of tree tip pointed electrode 112. Consequently, the charge possessed by the image receiving paper 108 is removed and the toner on the image receiving paper 108 is stably held thereon by mirror image force exerting between the toner and the image receiving paper 108 as a dielectric. Thus, even if the image receivnng paper 108 comes into contact with a carrying member 109, the toner is never scattered.

Title: Magnetic recording medium
Inventor: OCHI MUNEYOSHI
IPC: C09D5/23
Filed: 1987-09-14
Abstract: PURPOSE:To suppress the drop out by dislodgment of powder from a tape slit part by forming the tape slit part of a magnetic layer to the hardness smaller than the hardness on the other parts. CONSTITUTION:An electron beam curing resin and a crosslinking agent are used in combination in addition to a thermoplastic resin which is usually used as a binder and coating and surface smoothing treatment are executed by an ordinary method at the time of preparing a magnetic coating compd. Electron beams are then projected on the surface of the magnetic layer through a special screen which absorbs the electron beams in order to cure the surface of said layer. The hardness of the magnetic layer surface varies with the quantity of electron beam irradiation at this time. The slit part is irradiated with the electron beam at the quantity smaller than in the other parts. The hardness in the slit part is thereby decreased and the damage of the magnetic layer in the stage of slitting the slit part is suppressed; in addition, the same rigidity as heretofore is maintained over the entire part of the tape.
