Title: Rotary damper having directionality
Inventor: KAWASHIMA AKIMORI
IPC: F16F9/14
Filed: 1993-03-26
Abstract: PURPOSE:To provide a rotary damper which allows an object for rotating to make free rotation in one direction and suppresses rotation in the opposite direction. CONSTITUTION:A rotary shaft 1 is installed inside of an enclosed casing 8 in which a fluid is encapsulated, and a projection 9 is formed on the inside of the casing 8 while another projection 6 is formed on the rotary shaft 1, wherein blades 4 are resiliently mounted which slide on the slide surface 10 of the first named projection 9. The blades in the valve part are opened and closed by the differential pressure of the fluid put in the casing so as to generate a rotational resistance with selectivity in the rotating direction, i.e., to suppress the rotation. The number of component parts can thus be decreased and also the construction be made small and slim.

Title: Drainage pump controller
Inventor: NAITOU CHIKAMI
IPC: F04B49/04
Filed: 1979-05-30
Abstract: PURPOSE:To remove the chattering of a switch for obtaining a stable operation of a pump by delaying the change of the water-level in a level detector part for maintaining the operation state of the switch longer and providing a sharp action of switching off. CONSTITUTION:During the operation of a drainage pump 9, when a vent tube 13 is closed by humidified water, the second water-storage chamber 6 is permitted for draught only through a small gap 19 of a holding part 18 for a float operation rod 15. Consequently, the lowering speed of the level of the humidified water in the water-storage chamber 6 is made very slower than that in the first water-storage chamber 5, and the operation state of a switch 16 is maintained for a long duration. Meanwhile, when the water-level in the second water-storage chamber 6 is lowered under the lower end of the vent tube 13, a great amount of air is introduced to send forth the humidified water ito the first water-storage chamber 5, and the water-level in the second water-storage chamber 6 is dropped in an instant to switch off the switch 16 sharply. This construction serves to remove chattering of the switch, and stabilize the operatin of the pump.

Title: Facsimile equipment
Inventor: MISHIMA KENICHI
IPC: H04N1/00
Filed: 1990-03-20
Abstract: PURPOSE:To inform an operation state to a user by a simple method by informing the operation state of a transmitting/receiving means or of a recording means while changing the ON/OFF period of an announcing means. CONSTITUTION:When communication is started, the green lamp of a state confirmation lamp 17 is turned on/off at the intervals of two seconds (lamp ON under communication) and incoming picture information is received. When the end of the communication is informed from a communication control part 10, the green lamp of the state confirmation lamp 17 is turned to the ON state. Afterwards, the number of received documents is temporarily stored in a RAM 3-2. An MPU 12 outputs an output request to a picture input/output control part 7 and before the request, however, the green lamp of the state confirmation lamp 17 is turned on/off at the intervals of 4 seconds. Thus, the operational state of the equipment can be easily confirmed by the state confirmation display.

Title: Local annealing apparatus for cylindrical structure
Inventor: MORITA SHIYOUJI
IPC: C21D9/50
Filed: 1978-06-09
Abstract: PURPOSE:To relieve weld of its residual stress to approx zero by providing a radiative heat insulator in the inside of apparatus in the neighborhood of welding coupler in an apparatus in which a heating element is provided in the inside of cylindrical structure in order to relieve its welding residual stress. CONSTITUTION:Using the heat insulator 6 and the heating element 4, a cylindrical structure is formed into a furnace body, and then the radiative heat insulator 7 is provided in the neighborhood of the welding coupler inside. When local annealing is made under such a condition, the amount of incoming heat is lessened to an extreme extent and thus the temperature at the position where the radiative heat insulator is located is lowered from its both ends, thus relieving the weld of its residual stress. The apparatus is effectively applicable to chemical plants under severe corrosive environments.

Title: Field-effect transistor
Inventor: KOBIKI MICHIHIRO
IPC: H01L21/338
Filed: 1984-04-05
Abstract: PURPOSE:To increase mutual conductance by forming a semiconductor operating layer so as to have a beltlike region, in which a base and a side surface are surrounded by a high-resistivity semiconductor substrate, while shaping a gate electrode on the beltlike region and the high-resistivity semiconductor substrate and forming a conduction channel in the semiconductor operating layer. CONSTITUTION:When negative voltage is applied to a gate electrode 6, a depletion layer 9 spreads from not only the upper section of a semiconductor operating layer 3 but also both side surfaces and a lower surface. The layer 9 is changed into a depletion state at low gate voltage because impurity density in a semi-insulating high-resistivity semiconductor substrate and a transition region is low. Consequently, a conduction channel 10 is formed in the semiconductor operating layer 3 because the depletion layer 9 extends from four surfaces of upper and lower surfaces and both side surfaces. When gate voltage is further elevated, a pinch-off is generated in the semiconductor operating layer 3 because the depletion layer 9 further spreads from four surfaces and the conduction channel 10 is narrowed. Accordingly, since the conduction channel is shaped in the semiconductor operating layer having high impurity density, mutual conductance is increased, and the stability of performance characteristics and reliability can be improved.
