Title: Actuator
Inventor: UEDA JUNZO
IPC: F15B11/10
Filed: 1990-11-27
Abstract: PURPOSE:To ensure high responsiveness, smoothen a direction change action and miniaturize the actuator by providing a first and second pumps in a plunger device which is advancing and retreating due to a difference between fluid pressure applied from both end surfaces, and applying pressure to each of both sides of a piston by means of each of the pumps. CONSTITUTION:A piston 7 is integrally provided with a plunger 6 in a cylinder 5, and outside these a first and second pumps 2, 3 driven by a first and second electric motors under control of a controller 40 are provided and communicated with chambers 10, 13 in the cylinder 5 via through holes 15, 27, 38. Pressure oil from the first and second pumps 2, 3 is introduced into the chambers 10, 13, and a difference between pressure applied to surfaces 7A, 7B of the piston 7 moves the piston 7. Consequently, high responsiveness and smooth action can be obtained and dimensions can be reduced.

Title: Evaporating device
Inventor: TOMITA HIDEO
IPC: F23D11/08
Filed: 1988-12-22
Abstract: PURPOSE:To prevent a reversal flow of evaporated gas by providing an axial vane which products a flow from the inlet to the outlet of the evaporating chamber and a fuel feeding nozzle pointed toward an atomizing means. CONSTITUTION:An axial vane 19 which produces an air flow from the inlet 3 to the outlet 4 of an evaporating chamber 5 is attached together with an inverted conical rotor 8 to the end of the motor shaft 7 in the evaporating chamber 5. The kerosene delivered from a fuel feeding nozzle 10 to the rotor 8 is widely sprayed and atomized from the circumferential periphery of the axial vane 19 due to the centrifugal force and is smoothly evaporated on the inner wall of the hot evaporator shell 1. When the air delivery ability of the burner fan 15 decreases due to the power supply fluctuation or the discharge resistance increase caused by wind, etc., the axial vane 19 comes into play to check the reduction of air for evaporation. Therefore, even though the air for evaporation passing through the gap between the inlet 3 and the rotor 8 does not form a uniform flow due to the displacement of said gap and the presence of the fuel feeding nozzle 10, the reversal flow of the evaporated gas can be prevented as the lowest speed of air for evaporation is be maintained by the axial fan 19 higher than that speed at which the reversal flow evaporated gas can occur.

Abstract: PURPOSE: To generate one or more secondary beam cover ranges in addition to a main formed beam radiation pattern by providing a second supplying horn to communicate with a first reflection surface of a main reflector to transmit and receive energy in a secondary beam radiation pattern. CONSTITUTION: The reflection surface 11 of a main formed reflector 10 is irradiated to transmit and/or to receive radiation energy in a first secondary spot beam radiation pattern range 30 by an auxiliary supplying horn 24. The pattern range 30 is used to cover a geographical area, for example, like Alaska 34.

The pattern range 32 covers the geographical area, for example, like Hawaii 36. Supplying horns 14, 24, 26 are moved in axial directions along each related beam axis to focus or to make a focus vague on the size of each related pattern range.  Furthermore, the auxiliary horns 24, 26 are moved along an effective focus surface 28 to vary positions of the pattern ranges 30, 32.

Abstract: PROBLEM TO BE SOLVED: To make it easier to design method for cooling a refrigerated chamber and a vegetable chamber by constructing a cooled air outlet to the refrigerated chamber and the vegetable chamber and a cooled air return opening by use of a cover provided at a back side of the two chambers. SOLUTION: Cooled air fed to a refrigerated-chamber duct 41 at a refrigerated chamber 11 side through an electrically driven damper 38a is blown into the refrigerated chamber 11 through an outlet 61 and is made to return to a cooling device 8 through a cooled air path constructed by a cover 40 disposed at a rear portion of a low temperature chamber 52. The cooled air for cooling the refrigerated chamber 11 returns to a return opening 66 through a cooled air return path 65 formed between a bottom 52a of the low temperature chamber 52 and a series of partition plates composed of a beam-like partition 62 and a partition plate 63 for separating the refrigerated chamber 11 and a vegetable chamber 10.  Therefore, because a system for circulating the cooled air to the respective chambers is employed in which the cooled air is blown out from a rear side and is made to return to the rear side, a cooled air path capable of uniformly cooling the respective chambers is easily formed.
