Title: Wafer detecting device
Inventor: IWANAGA TAKEHIKO
IPC: H01L21/67
Filed: 1986-05-15
Abstract: PURPOSE:To improve the reliability of wafer detection, by providing optical fibers, which guide light, which is inputted in light receiving ports in a wafer holder, to the light receiving part of a photoelectric conversion means, providing a means for detecting the presence or absence of a wafer on a wafer mounting surface based on the output of the photoelectric conversion means, thereby optically detecting the wafer in the wafer holder without a mechanical mechanism around the wafer holder. CONSTITUTION:When a wafer 8 is not present on light receiving ports 2, light 1 is inputted to optical fibers 4 through the light receiving ports 2 for the fibers. The light receiving surface of a photodetector 5, which is connected to the other ends of said optical fibers 4, is lighted. Therefore, the amount of the light detected by said photodetector 5 is large. Input to a detecting circuit 6 becomes large. Meanwhile, when the wafer 8 is set on a wafer holder 3, the light receiving ports 2 for the fibers are covered. The amount of the light detected by the photodetector 5 is decreased, and the input to the detecting circuit 6 becomes small. Since the input signal to the detecting circuit 6 is varied to the large and small values in correspondence with the presence or absence of the wafer on the light receiving ports 2 for the fibers, the presence or absence of the wafer can be detected when a comparator is used in the detecting circuit 6.

Title: Information processor with fail/safe function
Inventor: NAKAJO NAOYA
IPC: G06F11/20
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To reduce the size and cost of the information processor. SOLUTION: When a fault in any one of information processing circuits 101 to 10N is detected by its corresponding fault detector out of plural fault detectors 121 to 12N, a reconstitution means 16 outputs a command for reading out reconstitution data corresponding to the failed information processing circuit to a reconstitution enabling circuit 18. The circuit 18 constitutes a fail/safe circuit for reading out reconstitution data corresponding to the failed information processing circuit from reconstitution data stored in a reconstitution data storing circuit 20 and executing a part of the function of the failed information processing circuit based on the read reconstitution data. An input limit circuit 14 limits the output of an inputted input signal only to an input signal necessary for the fail/safe operation of the failed information processing circuit. The fail/safe circuit constituted in the circuit 18 outputs a substitutive output signal corresponding to the input signal inputted from the circuit 14 to output the substitutive output signal from an output switching circuit.

Filed: 1994-05-25
Abstract: PURPOSE:To improve the processing speed and to reduce the power consumption by providing an entropy decoder for discriminating a block termination code in coded image data and an inverse quantizer for setting zero for the result of multiplication in the decoder. CONSTITUTION:An inverse quantizer 64 is made up of a quantization table 64a, a multiplier 64 and a DCT coefficient address generator 64c. When an entropy decoder detects a block end code EOB, values given to inputs A, B of the multiplier 64b are forcibly set to be both zero. Then the operation of the multiplier 64b is stopped and the power consumption is reduced. Furthermore, after the detection of the EOB code and after an output U of the multiplier 64b is zero, a DCT coefficient whose value is zero after that is independent of the operation of the multiplier 64b. Then the processing speed is improved by generating the DCT coefficient address corresponding to a generator 64c regardless of the operation of the multiplier 64b.

Title: Aeration-drying device for grain
Inventor: ITATSU YOSHIHIRO
IPC: F26B25/00
Filed: 1988-05-06
Abstract: PURPOSE:To enable a uniform drying to be carried out by a method wherein a crop particle sensor for storing a predetermined amount of crop particles by detecting the crop particles and another crop particle sensor for detecting a uniform layer and terminating a discharging of the crops when some crops at the central part are discharged and the crops are not detected are provided. CONSTITUTION:A crop particle sensor 4 arranged at a circumferential wall of a storing tank 2 is installed at a predetermined position of a predetermined crop particle accumulation layer at a peripheral edge. When this crop particle sensor 4 detects the crop particles, a supplying of crop particles is stopped, thereby a crop particle sensor 5 at a central part is buried and positioned in a crop particle layer. Then, when a small amount of crop particles are discharged from a central part of a bottom plate 3 of the tank 2, a surface of the crop particle layer at the central part descends. A crop particle sensor 5 is exposed at the surface and the crop particles may not be detected. When a discharging of the crop particles is terminated, a thickness (a) of aeration crop particles from the bottom plate 3 becomes substantially uniform. After this operation, air is aerated from the surface of the bottom plate 3 to the crop particle layer by an aeration means and thus a uniform drying can be carried out.
