Title: Powdery or granular material discharger
Inventor: ONO HAJIME
IPC: B65G53/36
Filed: 1980-06-18
Abstract: PURPOSE: To smoothly discharge the entire amount of a powdery or granular material without reducing the capacity of a tank, by applying air to discharge the powdery or granular material and by using push plates to move the material toward the opened part of a discharge pipe.  
     CONSTITUTION: To discharge a powdery or granular material, a compressor 19 is driven to supply air to chambers 11, 12, 13. When a valve provided in a discharge pipe 9 is opened, the powdery or granular material near the opened part of the discharge pipe 9 is fluidized by the pressurized air and conducted under pressure out of a tank 1. At the same time, push plates 10, 10' are thrusted toward the center of the tank 1 because there is a large pressure difference made between the central chamber 12 and the front and rear chambers 11, 13, so that the powdery or granular material is moved toward the opened part of the discharge pipe 9.

Filed: 1994-04-21
Abstract: PURPOSE:To lessen the displacement of pattern positions occurring in production process and to improve positional accuracy by forming an X-ray transmissive thin film to a narrow region by limiting the region to a part covering the region of an X-ray transmission window. CONSTITUTION:This mask blank has X-ray absorptive patterns 3', the X-ray transmissive thin film 2' holding these X-ray absorptive patterns 3' and a supporting frame body 1 for supporting the X-ray transmissive thin film 2'. The thin film to form the X-ray transmissive thin film 2' is so formed as to cover the region of the X-ray transmission window and is supported at the supporting frame body 1 in the region of the slight width in the outermost peripheral part of the thin film. Namely, the X-ray transmissive thin film 2' and rear surface protective film 4 having the tensile compressive stress to be the cause for the position displacement of the absorptive patterns 3' of the X-ray mask are formed to a small area by limiting their area only to the part covering the region of the X-ray transmission window. Then, the total stress generated in the frame body of the base after the back etching stage of the final Si substrate 1 is made small an eventually, the positional change of the absorptive patterns 3' is lessened.

Inventor: ISHIHARA KOJI
IPC: G01M3/02
Filed: 1986-04-12
Abstract: PURPOSE:To detect a leakage location correctly, by fetching a high frequency noise signal exceeding 100kHz from noise signals obtained with a microphone mounted on a pig to enable detection of a possible leakage however small the leak of gas may be. CONSTITUTION:Noise signal obtained with a microphone 6 are sent to a filter 7 while a pig 1 is running. Out of the noise signals, only high frequency noise signals exceeding 100kHz pass through a filter 7 and then, sent to a signal processor 8, from which they are sent to a memory 9 to be memorized thereinto 9 corresponding to a running distance of the pig 1 with a distance meter 5. This enables correct detection of a gas leakage location along with a judgment on whether a gas leakage occurs in a pipe 3 or not by analyzing data memorized in the memory 9 afterwards.

Title: Tape middle point detector
Inventor: ABE FUMIYOSHI
IPC: G11B27/17
Filed: 1986-04-11
Abstract: PURPOSE:To quickly fast forward and rewind a tape by obtaining extents of rotations from certain points to another points of a tape supply reel and a take-up reel and detecting the middle point of the tape in accordance with these extents of rotation. CONSTITUTION:When the tape is rewound from the tape end, the diameter of winding of a supply reel 1 is about zero and that of a take-up reel 2 is maximum, and they are in the unbalanced state. When rewinding is started in this state, the extent of rotation of the supply reel 1 is larger than that of the take-up reel 2 and when the unbalanced winding diameter state is inverted between two reels and the diameters of winding of both reels are changed to each other, the integral extents of rotation from the start of rewinding of both reels coincide with each other. Since the tape top or the tape end does not exist until the extents of rotation of the supply reel 1 and the take-up reel 2 are equal to each other after the start of tape running, the tape can be transported at high speed then, and the tape speed can be accurately reduced a certain time before the extents of rotation of both reels coincide with each other.

Title: Time division multiplex method and device for digital video signal
Inventor: SHIMOZAKA NAOKI
IPC: H04N7/171
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To send a multiplex signal in an optical transmission system without error by conducting scrambling in a stage number higher than the multiplexity and giving an inverted input signal to a time division multiplexer so that bit inversion takes place at least once in one frame. SOLUTION: A parallel scrambler 1 is used to apply scrambling to an output of a time division multiplexer. Then the time division multiplexer 2 receives an output signal of the parallel scrambler 1 and an inverted signal of the output signals by inverting the output signal with a NOT element 3. In the case of transmission bit rate of, e.g. 143.1818Mb/s for the input signal, the scrambling characteristic polynomial of the parallel scrambler is expressed as p(x)=X<17> +X<2> C+1. The scrambling is conducted in a stage number higher than the multiplexity and the inverted input signal is given to the time division multiplexer 2 so that bit inversion takes place at least once in one frame. Thus, the multiplex signal is sent without error in the optical transmission system.

Abstract: PURPOSE:To calculate position at high accuracy by arranging plural optical elements that form a pair by a light emitting element and a photodetecting element in array-like form and making each pair of optical element emit light in order, and shortening interval of light emitting pulses to increase speed of scanning. CONSTITUTION:An element pair designating circuit C6 designates order of scanning for each pair of optical elements. Other photodetecting element near a photodetecting element that forms a pair with a light emitting element emitted light previously receives light by spread of light energy which is called directivity. Accordingly, a photodetecting element designated next is selected from elements which are off from previously designated photodetecting element and not influenced by energy of previous light emission. A judgement result storing circuit C7 correlates the result of decision S4 of the photodetected quantity for each pair of optical elements and signals S1 that indicate presently designated pair of optical elements and stores them. A position calculating circuit C8 reads out plural data S5 out of the result of decision for all past pairs of optical elements in the circuit C7, and calculates the presence of an object, size and its position.

Abstract: PURPOSE:To shorten the contacting time of a photo-mask and a semiconductor wafer, and to improve resolution by forming a groove to the vacuum chucking surface of a wafer chuck. CONSTITUTION:A cross-shaped groove 13 is formed to the vacuum chucking surface 12 of a wafer chuck 11. When a semiconductor wafer 22 coated with a resist film 21 is placed on the wafer chuck 11 of such structure and sucked by suction holes 14 under vacuum, a residual gas at a central section between the semiconductor wafer 22 and a photo-mask 25 is discharged smoothly under vacuum through a degassing path as a recessed section 23.

Title: Run length encoding device
Inventor: MIWA HIROAKI
IPC: H04N1/419
Filed: 1986-04-11
Abstract: PURPOSE:To increase the quantity of data compression by providing a means which encodes a counted value and a timing generating means which latches the counted value of a counting means in a latch means according to a signal from a data change point detecting means. CONSTITUTION:When data from an image reader varies, a timing generating circuit 2 stops a signal to the counter 3 temporarily and outputs a latch signal to a latch circuit 4 to latch the counted value of the counter 3 in the latch circuit 4. The timing generating circuit 2 outputs a clear signal to the counter 3, whose counted value is reset to 0, so that the counter 3 counts the next run length. The data in the latch circuit 4 is encoded by referring to data in a code ROM 5 and loaded on a shift register 6 with a load signal from the timing generating circuit 2 and outputted as serial data. Therefore, when all bits of the input data indicate white, the run length is the number of bits corresponding to the number of data of one page and a code corresponding to it is one kind. Consequently, data transmission with high compressibility is enabled.
