Title: Optical packet line concentration device
Inventor: FUKUDA TAKESHI
IPC: H04B10/27
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To concentrate optical signals at a lower discarding rate by converting the wavelength of optical signals exceeding the number of signals that an optical buffer can handle and feeding them back to the input terminal side of a spatial switch through a wavelength selecting means even when optical signals more than the above number are inputted at the same time. SOLUTION: A FIFO controller 240 when judging that the number of optical signals inputted to the spatial switch is larger than the number of signals that the optical buffer means can handle at respective points of time from received information of a packet receiving detector 110 converts the wavelength of only optical signals which exceed the number from λ1 to λ2 by the MμM spatial optical switch provided in front of the M×M spatial switch 130 and outputs them to the spatial switch 130. Further, the wavelength-converted optical signals are fed back to the input terminal side of the packet receiving detector 110 through a wavelength selector 262 and only optical packet signals of wavelength λ1 which do not have the wavelength converted are outputted to an output port 170 through a wavelength selector 261.

IPC: D06F33/02
Filed: 1991-02-08
Abstract: PURPOSE:To determine the washing time by the kind of dirt and the degree of dirt of the washing irrespective of a seasonal water temperature difference by controlling the speed of revolution of a motor by an output of each detecting means of the cloth quantity, a water level and a water temperature, and controlling the washing time by an output of a turbidity detecting means.

Title: Cathode-ray tube
Inventor: FUTATSUDERA MASAOMI
IPC: H01J31/10
Filed: 1982-02-08
Abstract: PURPOSE:To prevent the crack of a glass face by providing the residual distortion of the glass face in the direction perpendicular to the tube axis with a tension distortion at the central part of the glass face and a compression distrotion in the peripheral section. CONSTITUTION:Since the distortion which is neutral in the direction perpendicular to the tube axis generates a tension distortion toward the face peripheral section of a cathode-ray tube by the thermal expansion of the central part, the face generates a crack by the temperature difference between the central part and peripheral section. This event occurs since the central part is heated. If any residual compression distortion is previously reserved in the peripheral section, there is no possibility of growth of the crack during operation since the compression distortion is canceled and offset or reduced against the tension distrotion. To reserve such a residual compression distortion, a material with the large heating capacity of an asbestos plate 5 or the like is first heated beyond the slow cooling point and is then quenched below the slow cooling point 6 while it is being made to touch both surfaces of the central part 2. Since the peripheral 3 is quenched because the central part 2 is lacking of the asbestos plate 5, the residual compression distortion is reserved in the peripheral section 3.
