Title: Optical isolator
Inventor: ROBAATO EMU JIYOPUSON
IPC: G02B6/26
Filed: 1990-05-01
Abstract: PURPOSE: To reduce the size of an optical isolator by providing the isolator with a resonant cavity which can be tuned so that it resonates to a prescribed frequency. CONSTITUTION: The optical isolator has two linear polarizers 38 and 40. The resonant cavity 30 is placed between output line-type polarizers 38 and 40. A polarized light conversion means 42 for converting planar polarized light optical energy 46 received from the linear polarizer 38 into circular polarized light optical energy is incorporated between the input of the isolator and the resonant cavity 30. A polarized light conversion means 44 converting circular polarized light optical energy received from the resonant cavity 30 into planar polarized light optical energy is inserted between the resonant cavity 30 and the linear polarizer 40 at the output of the isolator. Namely, the resonant cavity 30 becomes a filtering medium for blocking reflected optical radiation. Thus, the isolator can be inserted into a chip or it can be made into a part of an optical fiber.

Abstract: PURPOSE:To reduce a dropping speed of hot metal by a method wherein molten metal fed from an opening part of a heat insulated container is discharged via a lower end opening of a container through an inner communication space of porous ceramic body arranged within the container. CONSTITUTION:A hot molten metal receiving device 8 is removable inserted or fixed in a circular hole 7 at an upper wall of a main body 3 of a holding furnace. Porous ceramic members 2a-2f are piled up within a funnel-like heat insulating container 1 of the device 8 from rough one to fine one of inner communication spaces from an upper end of a lower end thereof in sequence. In case that the molten metal is transferred, the molten metal 13 is fed from its upper end opening into the device 8, this molten metal passes through the inner communicating spaces of the porous members 2a-2f in sequence and discharged via a lower opening of the device 8. With this arrangement, it is possible to decrease a dropping speed of the metal and at the same time to remove obstacles in the molten metal. Accordingly, it is possible to prevent the obstacles in the molten metal from being adhered to the inner wall of the main body 3.

Title: Incinerator
Inventor: TANAKA AKIRA
IPC: F23G5/44
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To enable feeding of a matter to be treated to the full capacity with a higher combustion efficiency by arranging a forced blowing injection pipe concurrently serving as roaster at a lower part in a furnace and a vertically penetrable forced blowing injection pipe to vertically divide the inside of the furnace into a primary combustion chamber and a secondary combustion chamber. SOLUTION: A primary combustion chamber 4 is so formed to be wider at an upper part thereof and narrower at a lower part thereof with the inclined installation of a vertically penetrable forced blowing injection pipe 3 so that a matter to be treated fed from a feeding port 7 is compressed to be housed at the lower part by own dead load. As a result, the volume of the matter to be treated reduces as combustion from the lower part proceeds and the whole of the matter to be treated is moved downward sequentially by own dead load accordingly to be burned in succession near a forced blowing injection pipe concurrently serving as roaster for incineration treatment.  A secondary combustion chamber 5 is so formed to be wider at an upper part thereof and narrower at a lower part thereof with the inclined installation of the vertically penetrable forced blown injection pipe 3 so that a gas burned near a furnace floor 1a ascends through the secondary combustion chamber 5. Thus, the gas passes heating the side of the matter to be treated on the side of the secondary combustion chamber 5 housed in the primary combustion chamber 4 thereby contributing to the combustion of the matter to be treated on this side.

CONSTITUTION:A field insulating film 2, a gate insulating film 3, gate electrodes 4G1 and 4G2 are formed on a Si semiconductor substrate 1. The thicknesses S of the electrodes 4G1 and 4G2 are unitarily determined also by the limit of a present technique at its width W1 and interval WS. Accordingly, even if the thicknesses S and limiting sizes of the electrodes 4G1 and 4G2 are employed to determined a line and space (occupying area), the width of the gate electrodes G1 and G2, i.e., the length of channel become longer than the initial set, thereby suppressing a short channel effect. Thus, the width of a line is increased, and the length of the channel can be increased.

Title: Method for measuring temperature in living body
Inventor: SAITOU YOSHIAKI
IPC: A61B5/01
Filed: 1982-06-30
Abstract: PURPOSE:To measure temperature in a living body in safety over a long period, by impressing energy which is emitted by a variable-frequency oscillator at the outside of the living body, to a crystal oscillator which is implanted into the living body, and recognizing a frequency at which said energy is absorbed, and thus detecting the temperature in the living body. CONSTITUTION:High-frequency energy from a variable-frequency oscillator 5 is radiated by a coil 3, and is transferred to a coil 2, and oscillates a crystal oscillator 1. When the frequency of the oscillator 5 and the resonance frequency of the crystal oscillator 1 coincide with each other, the oscillation of the crystal oscillator 1 becomes large, and absorbs energy. Then, the frequency at which the absorption of energy is caused is read with a frequency counter 6, by varying the frequency of the oscillator 5, under monitoring an energy detector 4. The value which is read by the frequency counter 6, reflects a temperature which the crystal oscillator 1 implanted in a living body receives from the surrounding living body.
