Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To absorb time variation of signal light level or level difference between signal lights by branching a wavelength multiplexed signal light subjected to optical amplification through constant gain control and then subjecting the signal light of each wavelength to constant output level control through a specified number of variable optical attenuators. SOLUTION: N variable optical attenuators 7-1,...,7-n for controlling the demultiplexed signal light of each wavelength automatically to a constant output level are disposed between an optical demultiplexer 2 and respective light receiving units 3-1,..., 3-n (n is an integer of 2 or above). Output light level can be made uniform by demultiplexing a wavelength multiplexed signal light where a relative level difference appears between signals and controlling each signal light level by each variable optical attenuator 7-1,..., 7-n. Time variation of signal light level can be absorbed through the light receiving units 3-1,..., 3-n by setting the uniform level at an intermediate level in the input dynamic range thereof.

Title: Processing agent replenishment device
Inventor: TANAKA KATSUHIKO
IPC: G03D3/06
Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To obtain a processing agent replenishment device in which a container is surely loaded at a receiving part and a processing agent does not overflow from the receiving part. SOLUTION: When a bottle B is loaded in a liquid receiving part 36 and a processing agent flows out toward the receiving part 36, the processing agent is fed to a replenishment tank 12 through a liquid feeding pipe 40. Since an overflow port 82 is formed at the receiving part 36, the processing agent overflowing from the port 82 is discharged to a liquid receiving pan 86 through an overflow tube 84 even when the pipe 40 is clogged by some reason. Thus, the processing agent does not overflow from the receiving part 36.

Title: Manufacture of permanent impact-resistant aluminum rivet
Inventor: PEETAA BINSHIIRUTSU
IPC: C22C21/00
Filed: 1984-08-10
Abstract: Rivets for use in the aircraft industry are made from a wrought aluminum alloy (Material No. 3.1324 in accordance with DIN). As that alloy will precipitation-harden at room temperature, the rivets must be closed immediately after they have been annealed and quenched. The time in which the rivets can be deformed can be extended to as much as one week if the rivets are stored below -17 DEG  C. In order to overcome said disadvantages in the processing of the rivets, 0.002 to 0.3% cadmium is added to the wrought aluminum alloy. The resulting modified material exhibits a delayed precipitation hardening at room temperature and even when it is fully precipitation-hardened has a very high ductility. For this reason the precipitation hardening will not impose restrictions as regards the time in which rivets made of said alloy can be closed.

Abstract: PROBLEM TO BE SOLVED: To house units in a multimedia information board without producing any dead space in the board by deciding the dimension of the housing of each unit to the value obtained by subtracting the mount of a clearance from an integral multiple of a unit dimension. SOLUTION: The dimension of the housing space of a multimedia information board 1 is set at an integral multiple of a unit dimension and the dimension of the housing of each unit 3 housed in the board 1 is set at the values obtained by subtracting the amounts of clearances from the multiple variable of the unit dimension. Since the unit dimension which is known as the dimension of a circuit breaker for the agreed wiring of lighting panel boards has a width of 95±5 mm, the width W and height H of the unit dimension are respectively set at 90 mm and 34 mm based on the unit dimension. Therefore, the width and height of a base 11 are respectively set at 180 mm and n×34 mm (n is an appropriate positive number). Since the sizes of the information board 1 and unit 3 are set in the above-mentioned way, the board 1 can be used combinedly with a circuit breaker and, conversely speaking, a box for panel board can be used as the board 1.
