Title: Autotensioner for belt
Inventor: KADOTA YASUSHI
IPC: F16H7/12
Filed: 1986-06-06
Abstract: PURPOSE:To obtain the simple structure and reduce dimension and cut cost and permit the simple assembly work by allowing the annular sealed space between the rotary members to be charged with high viscosity oil. CONSTITUTION:When a bracket 17 turns, the capacity between the projections 21 and 22 in a sealed space 20 varies, and the high viscosity oil O flows, passing through the gap between the projections, and since the gap is small, the fluid resistance is large. Since the extension and contraction of a belt 26 are very gentle, also the revolution speed of the bracket 27 is very small, and the restraint for the revolution of the bracket by the oil O is prevented. Further, the vibration of the belt 26 and the vibration of an idler 24 and the bracket 27 due to the engine vibration can be suppressed by the fluid resistance of the oil which tends to flow through the gap between the projections. Therefore, the structure can be made simple, the dimension reduced, the cost cut, the installation space reduced, and the simple assembly work permitted.

Inventor: KANBE TAKASHI
IPC: G01B11/00
Filed: 1981-08-24
Abstract: PURPOSE:To eliminate erroneous distance measurement by limiting the output of the output stage of a photodetecting circuit, which responds to even a DC input component to some extent, before the output stage enters into a saturated state against an excessive DC input component.

Title: Helical coil type nuclear fusion device
Inventor: IMAGAWA SHINSAKU
IPC: G21B1/11
Filed: 1988-06-01
Abstract: PURPOSE:To prevent the generation of permanent strain in a helical coil and the failure of the insulation of the helical coil by pressing the helical coil always with approximately specified force. CONSTITUTION:Plural pieces of bridge materials 5 divided in the winding direction of the helical coil 3 are interposed between the opposite walls of the coil groove 2 of a vacuum vessel 1 having the helical coil groove on the outside surface of the helical coil 3 wound in the groove 2. The bridge materials 5 are connected by members 6 having the Young's modulus smaller than the Young's modulus of the helical coil 3. The elongation of the members 6 to generate large reaction force between the bridge materials 5 and the helical coil 3 is prevented by such constitution at the time when the helical coil 3 is displaced outward by thermal expansion and prescribed tensile force during energization thereof. The helical coil 3 is pressed under the prescribed force by the bridge materials 5 if the bridge materials 5 are connected under the prescribed tensile force by the members 6. The generation of the permanent strain of the helical coil 3 and the failure of the insulation of the coil are thus prevented.

Title: Gas combustion controller
Inventor: UEMATSU HIDEO
IPC: F23N1/02
Filed: 1983-07-20
Abstract: PURPOSE:To set an air ratio to a low value over a wide combustion range and to improve air-resisting performance, by preventing the occurrence of an uneven air ratio at a low combustion range. CONSTITUTION:A device comprises a differential pressure detecting means 9 for detecting a difference between a pressure produced between a gas amount regulating means 2 and a variable gas throttle 3 and a pressure generated between a blower 5 for feeding the air for combustion and a fixed air throttle 6, and an air amount regulating means 10 for controlling the blower 5. The device is further provided with an electric controller part 13 which controls the variable gas throttle 3 and the gas amount regulating means 2 so that a throttle opening can be switched to the increased or decreased size when a combustion amount attains a previously set value, whereby a gas amount and an air amount are proportionally variably controlled over an entire combustion variable range, and in a range in which a combustion amount is below a previously specified set value, the throttle opening of the variable throttle 3 is switched to the reduced size, and control is effected in an increasing air ratio. This enables modification of a state in which an air ratio is sharply decreased especially in a low combustion range due to control error of a differential pressure detecting means, and permits improvement of air-resisting performance of combustion devices.
