Title: Pressure fixing device for photoelectronic copying machine
Inventor: UEISHI YUKIHIRO
IPC: G03G15/20
Filed: 1981-05-30
Abstract: PURPOSE:To obtain always prescribed fixing performance by mounting a pressure setting device variablly setting a pair of roller elements and the pressure applied by the roller elements according to the thickness of a toner carrying sheet to be used. CONSTITUTION:When the leading edge of a toner carrying sheet is inserted between detecting rollers 24, 25 of a detector 23, the detecting roller 25 is separated from the ddtecting roller 24 according to the thickness of the sheet and a swing arm 27 starts to rotate. Consequently, a differential transformer 28 outputs an electric signal to a controlling device 21 according to the rotational speed of the arm, namely, the thickness of said sheet. The controlling device 21 finds the proper rotational angle of a pulse motor 18 according to the electric signal and outputs a control signal to a pulse generator 20 after passing a prescribed period from the time the electric signal has been received. Therefore, when the leading edge of the sheet is inserted between the roller elements 6, 7, the pulse generator 20 outputs a prescribed pulse signal to the motor 17, so that the sheet is pressed with prescribed pressure by the roller elements 6, 7 and a toner image formed on the sheet is fixed by pressure.

Abstract: PURPOSE: To provide a fluid bearing, in which lands continuous in circumferential direction are formed between a pair of axially spaced pockets and these pockets are communicated with each other by a conduit bored in the body of bearing, whereby it is enabled to increase dynamic rigidity of the bearing.  
     CONSTITUTION: When hydraulic fluid is supplied from hydraulic fluid supplying source to supply port 24, it is introduced into pocket 16 via annular groove 21 and nozzle 20a and also into another pocket 15 via conduit 17, thereby forming a fluid film between bearing surface 11 and the outer surface of shaft 13 to be journalled by the bearing. Hydraulic fluid in pockets 15, 16 is passed through the passages formed between lands 15a, 16a and 15b, 16b and discharged to outlet grooves 22, 23 and outlet ports 25, 26.

Title: Refrigerator
Inventor: KOGASHIWA NAOYUKI
IPC: F25B39/00
Filed: 1993-04-12
Abstract: PURPOSE:To improve oil return ratio to a compressor by providing the compressor, a condenser, a pressure reducing device and an evaporator and forming an inner surface which forms a refrigerant passage in an oil-repellent surface. CONSTITUTION:An inner surface 12a of a refrigerant pipe 12 of a condenser 2 is formed in an oil-repellent surface 12b by coating surface treating material. The refrigerant pipe 12 is a passage of refrigerant in the condenser 2. Oil 10 is discharged out of a compressor together with gas refrigerant and circulated within a refrigerator. At this time, however, if the refrigerant is liquid, the oil 10 is solved into the liquid refrigerant and circulated within the refrigerator together with the liquid refrigerant. But the refrigerant condensed into liquid by the condenser is likely to stay in a lower part of the inner surface 12a of the refrigerant pipe 12 because of its own gravity. On the other hand, the oil 10 having a high viscosity is likely to attach to an upper part of the inner surface 12a of the refrigerant pipe 12. In this instance, as the inner surface 12a is formed in the oil-repellent surface 12b, the oil 10 is repulsed. As a result, the oil 10 is easy to flow through the refrigerant pipe 12, circulate within the refrigerator together with the liquid refrigerant, and return into the compressor. Thus, oil shortage in the compressor can be prevented.

Title: Traffic sign post prevented from impact deformation
Inventor: KUNIYOSHI TOSHIO
IPC: E01F9/631
Filed: 1987-04-08
Abstract: PURPOSE:To prevent damage by impact caused by contact of vehicles by a method in which the upper end of a fixed strut set in the ground is cut off into a V-shaped form and a rotary strut attached with a sign board with bolts is attached to the upper periphery of the fixed strut. CONSTITUTION:A V-shaped cut 15 with projections 16 on front and back sides is formed on the upper end of a fixed strut 4, and stoppers 17 are fixed to both ends of the projections 16. A bolt 11 is inserted into a hole 14 formed near lower end of a rotary strut 3 and fixed with nuts 12. When the strut 3 so assembled is fitted into the upper part of the strut 4, the bolt 11 is stabilized on the bottom of the cut 15. When a vehicular body is brought into contact with the sign board, the bolt 11 goes up rotationally along the sloped face and collides with the stoppers 17, where the bolt 11 absorbs impact and returns to its original position. The deformation of the sign board can thus be prevented due to absorption of impact caused by collision of a vehicle.
