Abstract: PURPOSE: To effectively perform especially the radio wave/light wave transmission of space communication by providing a radio wave/light wave interface between modulated radio waves and light waves and wavelength-modulating the light waves to be transmitted. CONSTITUTION: A light wave/microwave interface is provided with a light wave reception circuit 30 and a microwave transmission circuit 39. The light wave made incident on the circuit 30 and the light wave originated from a local oscillation laser are detected by a diode 41 and the diode 41 generates electric signals at the difference frequency of the two light waves by the quadrature phase detection of an electric field and reproduces the spectrum of converted information. The IF is stabilized by a frequency tracking system 45 and the IF is appropriately selected by a filter 42 arranged around the system logic IF. For the output, after second frequency conversion, the one suited to a using frequency band width is transmitted from a microwave transmission circuit 39.

Title: Continuous vacuum impregnating apparatus
Inventor: KUNIMITSU NOBUKAZU
IPC: B29B15/12
Filed: 1990-10-12
Abstract: PURPOSE:To obtain a contiunous vacuum impregnating apparatus, which competely scatters bubble and the operability of which is favorable, by a method wherein fiber is introduced under continuous running state in a resin tank and brought into contact with resin liquid at the apex of a roll coater so as to impregnate the fiber with the resin liquid. CONSTITUTION:Fiber 6 is introduced through a guide bracket 11 from a lead-in part 7a in a resin tank 1 and brought at a somewhat rising gradient into contact with the apex of a roll coater 5 and withdrawn at a somewhat falling gradient from a lead-out part 7b through a guide bracket 11 outside the resin tank 1. Since the one third of the roll coater 5 is immersed at all times in resin liquid 2, the resin liquid rotates under the condition being adhered to the peripheral wall of the drum-shaped roll coater 5 so as to infiltrate the resin liquid adhered to the roll coater 15 in the fiber 6 in tension through the contact between the resin liquid and the fiber at the apex of the roll coater 5. Further, since the interior of the resin tank 1 is put under vacuum state, bubble is scattered. As a result, the fiber 6 is completely impregnated with the resin liquid before its withdrawal from the lead-out part 7n. Furthermore, since fiber is wound round not so many rolls, the roll does not also give a bad effect on the quality of the fiber.

Abstract: PURPOSE:To improve the track density and the bit density by connecting bases of 1st and 2nd transistors (TRs) to a magnetic head, connecting 3rd and 4th TRs whose emitters are connected in common to a load circuit, reading out a readout signal and applying a prescribed voltage to bases of the 3rd and 4th TRs in the write operation. CONSTITUTION:When a base current of TRs Q3, Q4 is neglected in the readout operation, since the resistance of resistors R1, R2 is identical, a mean voltage at terminals T1, T2 is fed to bases of the TRs Q3, Q4. Moreover, a collector voltage amplified by TRs Q5, Q6 of cascode connection is applied to collectors of the TRs Q3, Q4 receiving the operating input voltage at the terminals T1, T2. When switches SW 1, SW 2 are opened and SW 3, SW 4 are closed in the write operation, a write current flows to the magnetic head 1 and a voltage is generated at the terminals T1, T2, but when the voltage is set to (VH+VL/2), the TRs Q1 - Q4 are not in breakdown and the dielectric strength of a flyback transistor is doubled.

Filed: 1986-11-15
Abstract: PURPOSE:To prevent a reflected light from being inputted to a camera and to attain a satisfactory monitor by disposing a rib in the internal surface side of a filter between alight emitting element and the television camera. CONSTITUTION:A see-through window 20 is opened in a cover 3 and the two ribs 31 are integrally formed in the see-through window 20.

Title: Power circuit
Inventor: NORO MASAO
IPC: H02M3/28
Filed: 1991-09-25
Abstract: PURPOSE:To prevent a resonance frequency from differing among a plurality of outputs even when there is a difference in a leakage inductance among them, in the case when the leakage inductance of a transformer is used as an inductance for current resonance and a plurality of outputs are taken out from this transformer. CONSTITUTION:A DC power source 1 is switched by switching elements S1 and S2 alternately and impressed on a primary winding 20 of a transformer, voltages induced in a plurality of secondary windings are rectified and smoothed and thereby a plurality of outputs are obtained. The value of a leakage inductance between the primary and secondary sides of the transformer T1 differs for each of windings 11 to 13 (L1 to L3). When this inductance is used as an inductance for current resonance, capacitors C2a, C2b and C2c for the current resonance are disposed on the secondary side and values thereof are set appropriately. Thereby resonance frequencies in the windings 11 to 13 are made uniform.

Title: Band brake device
Inventor: SUGANO KAZUHIKO
IPC: F16H63/30
Filed: 1987-10-30
Abstract: PURPOSE:To get rid of an uncomfortable speed reducing feeling in the initial stage of starting speed change by supporting an anchor pin for supporting reaction force which acts on a band brake from a hydraulic servo piston, on a casing via a cushioning spring. CONSTITUTION:Since a cushioning spring 116 is placed on an anchor pin 108 side, it acts in a leading direction at the time of 2-3 gear speed change, being set in a characteristic of obtaining a proper cushioning effect in this condition. On the other hand, at the time of 1-2 gear speed change, the cushioning spring 116 acts in a trailing direction reducing the cushioning effect thereof, always generating a cushioning effect in a portion lower than the oil pressure of an accumulator. Thereby, it is prevented that the torque at the time of 1-2 gear speed change is greatly reduced, obtaining a proper speed change feeling.

Title: Safety device for passenger conveyer
Inventor: SAITO KUNITOSHI
IPC: B66B29/00
Filed: 1988-10-31
Abstract: PURPOSE:To improve the safety of passengers without any sacrifice of design and mis-operation by detecting only the load in the vertical direction applied to a handrail when a passenger hangs out of the handrail. CONSTITUTION:When a passenger hangs out of a handrail 6, an upper guide 4a deflects downwards by the component P' of the load P in the vertical direction applied to the handrail 6 to make a tape switch S come into action. The action of the tape switch S actuates an alarm device to call his attention and makes control such as the operation of a controller for stopping traveling a passengers' conveyer. The detector for a passenger's hanging out of the handrail 6 is built in the guide 4 of the handrail 6, which causes no mis-operation even if a passenger gives a force in the rotational direction to the handrail 6 and improves the safety of passengers on a passengers' conveyer.

Abstract: PURPOSE:To allow a smooth sliding of a wire rack and prevent it from falling by making up a heating chamber with heat-resistant, corrosionresistant sheet metal, and fitting spring bodies to the wire rack that contact and press against the side wall of the heating chamber. CONSTITUTION:The heating chamber 2 is made up with stainless steel sheet metal, and the side walls 2a, 2b of the heating chamber have an opposing pair of projecting rails 2c, 2d which are formed by drawing, A pair of leaf springs 5a, 5b are fitted to a wire rack 4 which is made up with wire material and is held in place by said rails 2c, 2d. The leaf springs 5a, 5b are pressed against the side walls 2a, 2b of the heating chamber by their resiliency. As a result, there is no rattle between the heating chamber side walls 2a, 2b and the wire rack 4. Therefore, the wire rack 4 does not fall out of the rails 2c, 2d even in the presence of a slight deformation in the heating chamber side walls 2a, 2b. If the space between the heating chamber side walls 2a, 2b became small due to a dimensional variance of the heating chamber 2 or external force, on the other hand, the dimensional variance can be absorbed by the resiliency of the leaf springs 5a, 5b, ensuring a smooth sliding of the wire rack 4.
