Filed: 1987-07-23
Abstract: PURPOSE:To enable specified amplification regardless of the polarization state of incident light by separating signal light to orthogonally intersecting linearly polarized waves, then projecting the waves in the same linearly polarized wave state on respective optical amplifiers 10 to amplify the waves and multiplexing the waves again. CONSTITUTION:The light signal 20 propagated in an optical fiber 11 is separated by a polarized light coupling and separating device 12 to the orthogonally intersecting linearly polarized waves 21 and 22. The progressive wave type semiconductor laser optical amplifier 12 is used for the optical amplifier.

Title: Heat transporting system
Inventor: SUZUKI KATSUHISA
IPC: F24J2/44
Filed: 1983-09-29
Abstract: PURPOSE:To eliminate a circulating pump and a compressor by a method wherein a closed working fluid circulating circuit consists in connecting an evaporator, a condenser and a working fluid reservoir with conduits and the working fluid in the working fluid reservoir is heated. CONSTITUTION:The vapor pressure in a working fluid reservoir 2 is raised by the heating of the reservoir 2 with a heater 9, resulting in raising a working fluid in a liquid lifting passage 4, an equalizing passage 14 and a liquid lowering passage 6 in the same manner at first. However, after a while the liquid lowering passage 6 is blocked by a check valve 16 and the equalizing passage 14 is blocked by a float valve 15, resulting in allowing for only the working fluid in the liquid lifting passage 4 to keep on rising so as to be heated and vaporized by the solar heat in an evaporator 1 and flowed in a condenser 3 in order to release heat and condense by means of a coiled pipe 13. When the level in the working fluid reservoir 2 lowers below the lower end of the equalizing passage 14, the working fluid locating below the float valve 15 falls down in the reservoir, resulting in opening the float valve 15 and consequently equalizing the pressures in the working fluid reservoir 2 and in the condenser 3 and accordingly opening the check valve 16. By repeating similar action, the solar heat is transmitted to water through the channel of the latent heat of phase transformation of the working fluid.

Title: Control circuit for tuning voltage
Inventor: SAKAMOTO KAZUAKI
IPC: H03J5/02
Filed: 1985-08-20
Abstract: PURPOSE:To omit a changeover switch connecting selectively a presetting circuit and an optional channel selecting circuit as well as to avoid such a case where the difference of impedance between both circuits gives effects with each other, by connecting the outputs of both circuits to a variable capacity diode via a diode respectively. CONSTITUTION:A presetting circuit 20 and an optional channel selecting circuit 21 are connected in parallel between a power supply terminal +B and an earth. A switching transistor (TR) 25 is kept ON while a switch 32 of the circuit 21 is kept OFF. Thus the tuning voltage set previously by a semi-fixed resistance 22 is impressed to a variable capacity diode 38 via a diode 34. While a local oscillation circuit 37 delivers a frequency resonant with the channel frequency set previously and a preset channel is selected automatically. When the switch 32 is turned on, the TR 25 is turned off. Then the tuning voltage of the circuit 21 is delivered via a diode 35 in place of the output of the circuit 20. The tuning voltage of the circuit 21 can be varied optionally by a variable resistance 27. Thus an optional channel is selected.

Filed: 1992-06-18
Abstract: PURPOSE:To obtain a patterned transparent platy material by forming a lightweight threadlike body into a complicated pattern and interposing the threadlike body between two platy members without deforming the pattern. CONSTITUTION:A threadlike body 4 and low-melting fiber 5 melting at a relatively low temperature are employed and either is used as weft or warp yarn to construct a woven fabric.

The same resin films 6 and 7 as the low-melting fiber 5 are superposed and nipped between two platy members 2 and 3 in the form of a sandwich and heated under a reduced pressure. Thereby, the low-melting fiber 5 and the resin films 6 and 7 are melted while maintaining the pattern of the MIZU-GOROMO formed from the lightweight threadlike body to completely bond the two platy members 2 and 3. As a result, the objective patterned transparent platy material is produced.

Abstract: PURPOSE:To prepare Si3N4 having high nitridation degree, in high efficiency, precluding the possibility of the contamination with impurities, by contacting metallic silicon added with a nitrogen-containing silane compound with a nitriding gas at high temperature. CONSTITUTION:Metallic silicon having powder size of 150-400 mesh and purity of >=90% is mixed with 5-30wt% nitrogen-containing silicon compound (e.g. silicon diimide) with particle diameter of <=1mum, and the powdery mixture is nitrided by heating at 1,450-1,600 deg.C in a nitriding gas (e.g. ammonia gas) atmosphere. Since the nitriding reaction proceeds rapidly without causing the sintering of metallic silicon, the reaction time for nitriding can be remarkably shortened.

Abstract: PURPOSE:To cut sewing thread with a slight force surely by letting the tip of a movable blade and the tip of a fixed blade pass each other in a state of flexibly contacting with each other after the movable blade reciprocates and catches a line of sewing thread. CONSTITUTION:The side face 18a of a guide member 18 is flexibly contacted with the tip 5a of a fixed blade 5 by an assisting force in a state in which a restriction by means of a restriction device 25 for preventing a movable blade 6 moving in the axial direction is released. When the extent of the movement of the movable blade 6 in the direction of the assisting force is restricted by the restriction device 25 in this state, the side face 18a of the guide member 18 that is contacted with the tip 5a of the fixed blade 5 is constantly kept at the same position, and the contacting pressure between the movable blade 6 and the fixed blade 5 is kept constant. When the movable blade is rotated, the side face of the guide member is contacted with the tip of the fixed blade at first, and then the movable blade is moved in the axial direction with rotating of the movable blade as the side of the guide member is pushed by the tip of the fixed blade. As a result, as such as state that the side of the guide member is flexibly contacted with the tip of the fixed blade is established, the tip of the movable blade and the tip of the fixed blade pass each other in the state that the tip 6a of the movable blade is flexibly contact with the tip of the fixed blade, so that sewing thread is surely cut.
