Title: Interference film type optical multiplexer and demultiplexer
Inventor: ISHIKAWA SHIGETA
IPC: G02B6/34
Filed: 1981-06-12
Abstract: PURPOSE:To reduce an optical axis shift due to thermal expansion and to suppress an increase in loss due to a heat cycle by using a polygonal prism, and arranging lenses, filters, and fibers nearly symmetrically on the optical axis. CONSTITUTION:On all flanks of heptagonal bulk glass 4 except one surface, interference filters 22-27 are formed, and a composite beam of beams lambda1-lambda6 emitted from an optical fiber 31 for incidence is converted by a lens 11 into a parallel beam, which is guided to the filter 22 through a spacer 51 and the bulk glass. The filter 22 allows only the beam lambda1 to pass through it and the transmitted beam is converged by a lens 12 and coupled with an optical fiber 32 for emission. Other beams differing in wavelength are all reflected by the filter 22, and travel in the bulk glass 4 again to reach the next filter 23. Similarly, the beams lambda2-lambda6 are distributed separately to optical fibers 33-37 for emission.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of trouble such that a temple is tightened on loosened by opening plural holes near the outer side face of the lens of spectacles, fixing a ring screw through the hole of the lens to the lens, bending the temple and passing its one end through the hole of the ring screw. SOLUTION: Plural holes sized for passing a ring screw 1 are opened on a lens 6. Then, a plastic washer 2 is inserted into the ring screw 1 and passed from the inside of the lens 6 to the outside as it is. The plastic washer 2 is passed outside the lens 6 and next, a metal flat washer 3 is passed, fastened by a nut 4 and fixed. Finally, the round rod of titanium or piano wire is bent twice horizontally at 90 deg. and vertically at 90 deg. at the ring section of the ring screw 1 inside the lens and inserted into the ring screw 1 as a temple 5 later. Namely, since the temple has no metal joint section, not only any unusable state caused by detachment or dropping does not occur but also the frame can be made light in weight.

Filed: 1982-05-26
Abstract: PURPOSE:To provide economic and uniform cooling of a bearing by a method wherein a steam pipe is connected to a single radiator device from each of both main shafts having a hollow chamber with work liquid enclosed in a bearing block and a liquid pipe is communicated with each of the main shafts from the radiator device. CONSTITUTION:When a bearing block 4 shows a higher increased temperature than that of another block 41, the work liquid in a hollow chamber 7 of the block 4 shows a higher volume of steam, steam pressure and temperature than those of liquid in the block 41 in case of evaporation, so that an evaporation latent heat corresponding to those above is taken to perform more cooling and the temperature of the block 4 is prevented from being increased higher than that of the other block. The hot steam evaporated in the hollow chamber 7 moves to a radiator 8 through a steam pipe 10 and in turn a cold steam evaporated in a hollow chamber 71 passes through a steam pipe 101 to the radiator 8 to condense and then is liquefied. Therefore, in the radiator 8, the hot and cold work liquids condensed and liquefied are mixed to be a uniformalized and returned to the hollow chambers 7 and 71 through liquid pipes 12 and 121, so that the temperature of the block 4 is decreased, the temperature of the block 41 is increased and a difference in the increased temperatures is restricted low.

Title: Image size switching circuit
Inventor: NAKAMURA YOICHI
IPC: H04N3/223
Filed: 1988-04-15
Abstract: PURPOSE:To correct the fluctuation of size due to the brightness of a picture by providing a circuit controllable for the S-correction voltage of a horizontal deflection circuit, detecting a voltage proportional to the increment/decrement of the S-correction voltage, and switching the size of a variable impedance element. CONSTITUTION:The DC voltage levels of the voltages at both ends of a capacitor 13 can be changed by driving a transistor 16 from a voltage terminal. Thereby, the horizontal size can be changed freely. For example, the voltages at both ends of the capacitor 13 are increased by reducing the resistance value of a resistor 17, and the S-correction voltage is decreased, thereby, the picture size in a horizontal direction can be reduced. Next, the voltages at both ends of the capacitor 13 are increased by reducing the picture size at the time of switching the vertical size. Therefore, the impedance of the variable impedance element can be increased when the voltages at both ends of the capacitor 13 are smoothened, and the fluctuation of a DC voltage is connected to the variable impedance element, and the voltages at both ends of the capacitor 13 increase. In such a way, a vertical feedback voltage is increased, then, the vertical size can be reduced. When the brightness of the picture is heightened, the picture size is changed so as to be increased, then, a charge quantity to a capacitor 9 can be increased. Therefore, the picture size can be reduced both in the vertical and horizontal directions based on the above principle of size switching.
