Title: Picture quality evaluating method
Inventor: SHIRASAWA TOSHIO
IPC: H04N17/00
Filed: 1989-03-25
Abstract: PURPOSE:To obtain picture quality evaluating method contributive to the automation of visual inspection by obtaining the variance value of every block by blocking a picture obtained by reverse conversion, and making the mean value of the variance value and the variance value the evaluation parameter of the quality of the picture. CONSTITUTION:The picture to be inspected and outputted by using a photosensitive drum is inputted by using a drum scanner 11, and is fetched in a frame memory 12. By using a picture correction circuit 13, the gamma-correction of the inputted picture is executed, and the picture after the gamma-correction is two- dimensional-DPT transformed by a high speed FFT board 14, and filtering is performed so as to leave only the frequency component of a strip desired to extract. Then, two-dimensional reverse DFT is executed by using the filtered data, and the variance value of every block area is obtained from a obtained picture. The parameter to show the degree of the stripe is obtained by using this variance value, and by using the mean value of the variance value of the block and the variance value as the parameter, evaluation close to the evaluation by a man can be executed.

Abstract: PURPOSE: To reduce the loss of low-boiling-point silane in the preparation of silicon by disproportionating low b.p. silane by using a solid catalytic bed for disproprotionation. CONSTITUTION: The steam of silane is fed together with a hydrogen gas into a vapor deposition container containing the silicon heating base body of a semiconductor grade to vapor-deposite silicon. Next, an outflow gas from the evaporation container is separated into the mixed body of the low b.p. silane and the outflow gas and after that, low b.p. silane enrich mixed body is mixed with another tetrachlorosilane, and the mixture is passed through the solid catalytic bed. The catalyst is, for instance, the polymerization body of styrene- divinylbenzene matrix to accelerate the disproportionation of hydrogen- containing silane and chlorine-containing silane, to produce a flow in which the content of chlorosilane and dichlorosilane is decreased, and the content of trichlorosilane is increased, and after that, the isolation and separation of the trichlorosilane are performed.  Thereby the low b.p. silane is converted into low volatile trichlorosilane, and it is collected efficiently and easily at low costs.

Abstract: PURPOSE:To improve diffusion efficiency and to make processing high speed by dividing input data into blocks of the same data length, taking in and resoluting data from the other block, and outputting a new diffusion data. CONSTITUTION:When diffusion output data of 32 bits is obtained from an input data of 32 bits, first of all, an input data block R of 32 bits is divided into process blocks R0-R3 of 1 byte. And each data is inputted to it, operation with the other data directly or indirectly performed at least one time, and a new data having same length as that of the input data is generated. After this process procedure, process blocks R0-R3 are supplied and they become output blocks, but each output blocks all are generated under influence of input blocks. Mutual interference between these process blocks is realized with form of input to an exclusive logic circuit XOR and a character resolution and substitution function operation section S. Therefore diffusion efficiency of data can be improved without using an inverted function.

IPC: E02D3/12
Filed: 1981-05-20
Abstract: PURPOSE:To prevent the occurrence of an improving agent loss and simultaneously to improve a ground improving effect, by a method wherein, after an implanting member for ground improving agent, provided with an excavating cutter at the end, is inserted under an anhydrous condition into a ground to be improved, the improving agent is implanted into an outer peripheral ground through the implanting member. CONSTITUTION:An implanting member A for ground improving agent is inserted under an anhydrous condition into a ground B as an excavation is carried out by means of an excavating cutter 5 at the end thereof. Then, an elastic toroidal segment 4 prevents earth and sand of an outer peripheral ground to enter the implanting member A. If a ground improving agent C is implanted into the outer peripheral ground through an implanting port 2, the agent C expands the elastic toroidal segment 4 in a direction of a diameter to implant it into the outer peripheral ground through a gap between the elastic toroidal segment 4 and a body (a). Like a time when the implanting member A is inserted underground as pressure water is jetted, this prevents the formation of a gap between the implanting member A and the outer peripheral ground and causes the implanted improving agent to be implanted into a given ground immediately.
