Title: Optical transmission system, light wavelength conversion system, and reception system
Inventor: KIKUCHI NOBUHIKO
IPC: H04B10/2507
Filed: 1991-06-26
Abstract: PURPOSE:To provide the wavelength conversion system which eliminates the need for the countermeasure for polarized wave variation, eliminates the influence of a phase noise of a light source, and facilitates the cascade connection of a wavelength converting element. CONSTITUTION:A signal light source 100 and a pump light source 110 are arranged in a transmitter and polarized waves of the both waves are matched and sent. An optical amplifier 104 compensates the transmission loss of both the light signals, adds converter light 105, and inputs them to a semiconductor optical amplifier 106. A band-pass filter 107 extracts wavelength-converted light beams generated on both sides of the converter light by mixing the converter light and four light waves in the semiconductor optical amplifier and uses them as the output light of the wavelength converting element. A receiver performs heterodyne reception by using the converter light as local oscillation light. When the wavelength converting element is cascaded, the converter light is used as the pump light of a wavelength converting element in a trailing stage. Consequently, the need for the countermeasure for polarized wave variation is eliminated and the phase noise of the converter light is canceled.

Filed: 1987-06-22
Abstract: PURPOSE:To surely supply oil to a lubricating part, by providing a center oil path, supply holes and an orifice hole in a transmission shaft and mounting a check valve to the supply hole. CONSTITUTION:A transmission provides a center oil path 130 to be drilled in the center part of a transmission shaft 31, and this center oil path 130 communicates with an oil reservoir through an oil path 132, inner side oil path 52 through a pair of supply holes 137 and each part of the transmission through an orifice hole 151. The transmission, which mounts a supply pump interposing halfway the oil path 132, provides a check valve 138, preventing a reverse flow of oil from the inner side oil path 52, in the supply hole 137. In this way, if the inner side oil path 52 generates a pressure lower than that in the center oil path 130 by the leakage of oil, the operating oil is supplied to the inner side oil path 52 by opening the check valve 138. While oil in the center oil path 130 is supplied to a lubricating part through the orifice hole 151. Accordingly, the oil can be surely supplied to the lubricating part with no trouble of supply of the operating oil to the inner side oil path 52.

Title: J1c fracture-toughness testing method
Inventor: UNO HIROSHI
IPC: G01N3/08
Filed: 1984-07-27
Abstract: PURPOSE:To obtain an accurate R curve, by providing many measuring points of compliances after the maximum value of the load/displacement curve rather than in the region before reaching the maximum value. CONSTITUTION:A load/displacement curve is obtained by using a test piece in which ideal cracks are provided. Said test piece is made of the same material for a CT test piece 1. A region before the maximum value of the curve is divided into equal parts of n1. Thus measuring points n=1-k of compliances are set. A region after the maximum value is divided into equal parts of n2, which are more than the equally dividing number n1 before the maximum value. Thus measuring points n=K+1-n of the compliances are set. Thereafter an actuator 5 is operated and a load is made to act on the CT test piece 1. The load/displacement curve is recorded by a load cell 3 and a displacement gage 2. The load is removed at each measuring point before and after the maximum value. The compliance at each point is obtained. The grown amount of the crack is computed based on the value, and the R curve is obtained. The value of J1c is obtained from the intersection of the R curve and a blunting straight line.

Title: Transfer tube
Inventor: POORU SUTEIIBUN SUBETSUKU
IPC: B22D41/50
Filed: 1990-06-15
Abstract: PURPOSE: To prevent accumulation of a thermal stress adversely affecting a high density tube by comprising an integrated transfer tube of a high density ceramic oxide tube having an outer face wall covered with a low density ceramic oxide material. CONSTITUTION: A thermal conductivity of a low density shell 6 is considerably lower than a thermal conductivity of a high density tube 2. A thermal conductivity of the shell 6 is sufficiently low enough to prevent an extremely detrimental high thermal gradient at an outer wall of the high density tube 2. Further the shell 6 prevents the trouble that the high density tube 2 is crushed and its fractured piece enters into a metal passing through. Because the shell 6, of low thermal conductivity, is directly joined to the high density tube 2, the thermal gradient interposing a wall of the high density tube 2 is sufficiently lowered, the transfer tube is effective for transferring a molten metal.

Filed: 1993-06-25
Abstract: PURPOSE:To enable the reuse of a unit and unit material by fastening a plurality of unit parts together by means of a fastening member in the condition that it can be cut from outside of the unit parts. CONSTITUTION:An image forming unit 1 is formed by fastening an upper cover 12 to a lower cover 13. A band-like groove 14 is previously formed on an outer- fitting cover 11 so as to bridge the upper and lower covers 12, 13 when the upper cover 12 is connected to the lower cover 13. The groove 14 serves as a holding part with holds a band-like fastening member 16 at a fastening position.

Filed: 1978-12-15
Abstract: PURPOSE: To avoid the dust included in measured fluid from beng invaded in the space formed between the shell of the wing wheel of meter and the cone member.  
     CONSTITUTION: The mixing wings 19, 20 are fixed to the shell of the wing wheel 4 borne rotary free between a pair of upper and lower stream cone members 5, 6 held in the tube 2 consisting of a pair of tube parts 2a, 2b of the meter 1 which can be coupled and separated each other. With the rotation of the wing wheel 4, since the mixing wings 19, 20 turn, the swing flow around the shaft is caused at the circumference of the shell 4a. The dynamic pressure with the swing makes higher pressure for the vicinity of the gap 16 than measured fluid flowing the path 17. Accordingly, the measured fluid passing through the path 17 from the gap 16 between the shell 4a and the lower stream cone member 6 is avoided from being invaded in the space 22 and the choking of dusts to the bearing 9 can be prevented.
