IPC: F01K25/10
Filed: 1983-05-18
Abstract: PURPOSE:To permit energy economization by arranging liquid drainage piping on the inlet side of a low boiling-point medium evaporator and lowering the desinged pressure in a low boiling-point medium cycle, in a power generation plant which performs generation through utilization of the cold heat of LNG. CONSTITUTION:A medium having a low boiling point is evaporated in a medium evaporator 4, and said vapor is supplied into a turbine 6 and drives a generator 13. Said medium having a low boiling point is introduced into a medium condenser 1 and condensed by the cold heat of LNG supplied from a conduit 15. A liquid drainage valve 27 and conduits 28 and 29 are installed on the inlet side of the medium evaporator 4. The perfect closing signal for an LNG cut-off valve 16 sets the liquid drainage valve 27 into the perfectly opened state in about 1sec and recovers the working medium into a medium storage tank 23. The system pressure in a low boiling-point medium system can be reduced by reducing the amount of working medium during the time when LNG is cut off. Accordingly, since the cost of equipment can be reduced, and the prime cost for generation can be reduced, energy economization is permitted.

Title: Image recorder
Inventor: OGIWARA NAGAO
IPC: G03D13/00
Filed: 1987-04-10
Abstract: PURPOSE:To eliminate a cutting fault of a shaft even if pressure is applied for many hours, by allowing a bearing of a backup roller to have a self-aligning property. CONSTITUTION:The bearing 6 of a backup roller 3 is allowed to have a self- aligning property. When a photosensitive material and an image receiving material are superposed and brought to a pressure transfer, an application of pressure of the backup roller 3 is executed by pushing its bearing 6 by adjusting a bolt 4 by a spring 5, and in that case, a shaft 7 for supporting the backup roller 3 is bent. In that case, since the bearing 6 is a self-aligning ball bearing, a core of the bearing can be changed in accordance with bending of the shaft, therefore, a repeated stress to a root part 11 of the bearing of the shaft is obviated. In such a way, even if the operation is executed for many hours, it does not occur that the backup roller shaft is ruptured.

Title: Rotary compressor
Inventor: SAKAMAKI HIROSHI
IPC: F04C18/344
Filed: 1983-05-20
Abstract: PURPOSE:To check drum-form thermal deformation in a rotary sleeve to the utmost, by installing a layer comprising a composite material being smaller in a coefficient of thermal expansion than a base material of the rotary sleeve. CONSTITUTION:A rotary sleeve 17 consists of light metals and a light alloy such as aluminum, and aluminum alloy, etc., and at both ends of the rotary sleeve 17, there is provided with a layer 36 composed of a composite material of the aluminum alloy as a base material 35. This composite material 36 consists of such a material as being smaller in a coefficient of thermal expansion than the base material 35 of the rotary sleeve 17. Since a temperature differential is produced between inner and outer circumferential surfaces of the rotary sleeve 17, if the sleeve tries to deform itself into drum-form, the amount of thermal expansion in a radial direction at both ends of the rotary sleeve is held down to be smaller than other parts. Therefore, the deformation in the sleeve is thus checked to the smallest possible extent.

Abstract: PURPOSE:To obtain a desired antenna gain in a simple and assured way, by varying the direct current to be applied to an inductance connected electrically to a radio antenna element and thus controlling the tuning frequency of an antenna. CONSTITUTION:For a high frequency input circuit 11 of an FM tuner 10, a coil 12 and a capacitor (C) 13 are connected in series to form an antenna tuning circuit and a coil 14, C15 and a voltage variable diode (D) 16 are connected in series to form an input circuit. On the other hand, a slider 21 is driven for a variable resistor 19 with operation of a tuning knob 20 of the tuner 10. Thus a variable control is given to the D16 to control the tuning frequency of the circuit 11. The secondary side of a matching transformer 31 that forms an inductance L is inserted between elements 241 and 242 of a half-wave dipole antenna 24. The voltage of the slider 21 is applied to the primary side of the transformer 31 via a coaxial cable 27. Thus the inductance L receives a variable control, and accordingly the tuning frequency of the antenna 24 is always set equal to the receiving frequency.
