Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To reduce camera-shake by switching the standstill position of a supporting member to plural places with a switching means, simultaneously with the operation of selecting the shutter speed, that is, the exposure time. SOLUTION: In this curtain speed adjusting mechanism, in the shutter speed at a shortest shutter opening time, a control circuit, to which a selecting signal for the shutter speed by a shutter speed dial is inputted, actuates a step motor 13 by a specific rotational amount.

Title: Heat exchanger
Inventor: YAMAMOTO YOSHIAKI
IPC: F28D1/03
Filed: 1984-04-13
Abstract: PURPOSE:To improve temperature efficiency and obtain the heat exchanger having no biased flow of fluid in two-phase flow by a method wherein a fin member having a plural pairs of holes and a spacer member, provided with a pair of holes and a groove between the holes, are laminated to form the flow path of heat exchanging fluid by the holes and long holes. CONSTITUTION:Headers 15, 16 are formed by laminating the fin member 10 and the spacer member 12 so that the hole 11 of the fin member coincides with the hole 13 of the spacer member 12. Fluid A flows into the heat exchanger from the header 15 at the oulet side of fluid B. Thereafter, the fluid A is branched into the grooves 14 and is collected into the header 16 to flow it out. In this case the fluid A exchanges it's heat with the other fluid B in the condition of counter-flow since the groove 14 becomes a principal heat exchanging section. Accordingly, the temperature efficiency may be increased and there is no biased flow in the two-phase flow. The spacer member 12 can be formed by laminating two members 17, 19 and the members 17, 19 are consisting of through holes 18, 20, therefore, the member 12 may be produced inexpensively comparatively by press works or the like.

Title: Equipment for extracting kinetic energy by expanding high pressure steam in volute nozzle
Inventor: YAMANO MICHIZOU
IPC: F01D1/18
Filed: 1981-05-16
Abstract: PURPOSE:To efficiently convert energy of high pressure steam into energy of rotation by expanding steam from the vicinity of the center of rotation and covering a volute nozzle, rotated by means of reaction force and impulse force, with a disc-shaped cover. CONSTITUTION:High pressure steam, produced in a high pressure chamber 5 through combustion or vaporization, flows in from a volute nozzle inlet A and expands in the volute nozzle while being adjusted to maintain its predetermined quantity by means of a throat B. The volute nozzle rotates counterclockwise by means of reaction force and impulse force. Expanded steam is ejected from an outlet C on the periphery and nearly comes to a standstill. Since the volute nozzle is sheltered by means of a disc-shaped cover D, loss of kinetic energy due to a friction between the nozzle and the open air during its rotation is reduced. Rotatory power of the volute nozzle is transmitted to gear 6 through a shaft 1 of a round pipe and is extracted as motive power. Thus, even superhigh pressure steam of more than 300 atmospheric pressure may be expanded reasonably and extracted efficiently as energy of rotation.

Abstract: PROBLEM TO BE SOLVED: To accurately stop a supply of fuel by determining abnormality to stop the operation of a pump when a flame is not detected within a specified time after the starting of the pump while an open/close valve provided in a fuel supply pipe is driven to be closed. SOLUTION: When a combustion sensing sensor 37 detects a flame, the discharging of an electrode rod 35 is stopped and a combustion lamp 4 comes ON. On the other hand, when the flame is not detected within a specified time after the starting of an electromagnetic pump 22, a control means judges the frequency of the failed ignition and determines the abnormality of ignition except for once. A control is executed to stop the operation of the electromagnetic pump 22 and the open/close valve 39 is closed to stop the discharging of the electrode rod 35. The operation thereafter is halted. This can prevent the abnormality of ignition in which a fuel is continued to be injected from a fuel injection nozzle without the starting of combustion.
