Title: Restoring method for logic circuit diagram
Inventor: OE RYOICHI
IPC: G06F17/50
Filed: 1987-03-20
Abstract: PURPOSE: To restore a logic circuit diagram easy to be recognized by a designer, by enabling a data signal system and a control signal system to be recognized, and performing separated wiring by distinguishing both systems so as to recognize their wiring separately.  
     CONSTITUTION: Inverters 9 and 10 are selected based on the connection information of the logic circuit diagram. Next, transmission gates (5W7) to which the output terminals of the inverters 9 and 10 are connected are selected. The inverters 9 and 10 are not wired directly with the data signal system consisting of transmission gates (5W8) other than the gates connected to the inverters 9 and 10, and another circuit device, and the wiring is shown by a coupler, and also, a logic circuit where they are arranged separately in separated positions can be obtained. Since the gates 5W8 are controlled so that they are energized when an input clock pulse CK is set at an L level, and are de- energized when the CK is set at an H level, the inverters 9 and 10 constitute the control signal system. Since the control signal system is arranged separately from the data signal system, the logic circuit diagram easy to be recognized can be obtained.

Abstract: PURPOSE:To mask spatial frequencies at which MTF (modulation transfer function) values become the minimum and the minimum values of the MTF values variable, by arranging the surface of a half mirror and that of a mirror in parallel with each other and separating incoming rays into rays reflected by the surface of the half mirror and those reflected by the surface of the mirror after passing through the surface of the half mirror. CONSTITUTION:The optical filter 1 of this invention consists of a half mirror film 3 provided on one surface of an extremely thin glass plate 2 and a mirror film 4 provided on the other surface of the glass plate 2, and is assembled in the image picking-up optical system of a television camera in such an attitude that the opening angle beta between an incident ray 6 and its reflecting ray becomes 90 deg. after the filter is firmly fixed onto a glass base plate 5. When the distance between the surface of the half mirror and that of the mirror is changed, spatial frequencies at which MTF values become the minimum can be made variable. Moreover, the minimum MTF value can be made variable by changing the reflectivity of the surface of the half mirror. Therefore, MTF characteristics which can satisfy both the elimination of color beats and resolution can be obtained.

Abstract: PURPOSE:To prevent an unnecessary radiation irradiation to a patient by comparing an output signal with a sample holding circuit, to both upper and lower limit interlock level signals. CONSTITUTION:A sample holding circuit 10 of a device samples a peak value of a plateau part of radiation pulses. An output of the circuit 10 is fed to comparators 12 and 13, after being regulated in the level by an amplifier 11 for a gain regulation. In case that an output of the amplifier 11 stays between the upper limit value and the lower one being set by a highest permissible level setter 13 and a lowest permissible level setter 15, a radiation output stays within a permissible energy range and both outputs of the comparators 12 and 14 become to be 'H', and therewith an interlock circuit is not activated. Otherwise, in case that an output of the amplifier 11 exceeds an highest limit value of the highest permissible level setter 13, or does not reach the lowest limit value of the lowest permissible level setter 15, an output of the comparators 12 or 14, becomes to be 'L' and an output of an AND circuit 16 becomes to be 'L' as well, and consequently the circuit 17 is activated to stop a radiation output.

Title: Sand grinding and refining device
Inventor: INO TOMIO
IPC: B24B31/00
Filed: 1979-05-30
Abstract: PURPOSE:To provide a miniaturized sand grinding and refining device by passing sand through a  space between inner and outer rotating bodies having abrasives on the walls thereof to allow the  sand to be ground by the abrasives, moved upwardly in the space and recovered as refined sand. CONSTITUTION:Sand introduced from an inlet 11 into a bore 6 in an inner rotating body 7 drops  onto a bottom surface of an outer rotating body 3 as it is whirled and ground at the surfaces of particles thereof by the centrifugal effect of the inner surface of the inner body 7. The sand at the  bottom portion of the outer body 3, which is rotated in the direction opposite to the direction in which the inner body 7 is rotated, springs up as it is whirled by the centrifugal force. Whil the  sand rises rapidly in such a manner, a part of abrasives 2 on the inner surface of the outer body 3  and a part of the surfaces of particles of the sand contacting the abrasives 2 come off to form  dust. As the sand is ground by the abrasives 2, the sand and the dust advance upwardly through  a space defined by the inner and outer bodies 3, 7. The dust having a small mass rises at a high  speed into a dust collector, while the sand moves in the mentioned space for a long period time  to be ground. The residual dust contained in the sand coming out of the space is floated by agitator vanes 18 provided outside the outer body 3 and guided by a conduit into the dust collector.  The ground and refined sand is withdrawn from a discharge port 16.

Abstract: PURPOSE:To obtain a lithographic plate enhanced in printing resistance even when an amt. of silver used is low, by controlling all the layer contg. gelatin in the lithographic plate applying the silver salt diffusion transfer method to a pH value below the isoelectric point of the gelatin. CONSTITUTION:A gelatin contg. layer, such as a carbon black-contg. antihalation layer, is formed on a support of paper, glass, polyester, or the like, this layer is coated with a chemically and orthochromatically sensitized silver chloride emulsion, and after drying, an image receiving layer contg. physical development nuclei contg. palladium sulfide is formed on the emulsion layer. Each of these gelatin layers is controlled in pH after drying to a pH value below the isoelectric point of the gelatin with sulfuric acid or citric acid, or the like, and when two or more kinds of gelatins are used, it is adjusted to below the lowest isoelectric point. It is preferable to lower the pH value by at least 0.3 lower than that of the gelatin. A printing plate enhanced in printing resistance from the conventional one and is not damaged at the thin line parts of a silver image can be obtained by imagewise exposing this plate, developing, and drying it. This plate is used by insensitizing it to oil, and using a dampening water feeder.

Title: Rod steel for low temperature
Inventor: KUNITAKE TATSUO
IPC: C22C38/04
Filed: 1981-05-06
Abstract: PURPOSE: To provide the steel bar for a concrete structure which have low temperature properties improved, by specifying the composition and notch strength ratio of non refined steel rod.  
     CONSTITUTION: The steel rod for a low temperature has a composition comprising 0.05W0.4% C, 0.1W1.5% Si, 0.25W2.5% Mn and the remainder of Fe and impurities provided that Mn/C≥ 4.5 and the amount of total N in the impurities is 0.003% or less, and a notch strength ratio at -100°C of 1.0 or more. It is necessary for C to be larger than the lower limit for ensuring the minimum yield point prescribed in the standards and when C is larger than the upper limit, the notch strength at -100°C becomes smaller than a fracture load at a normal temperature. When Si is larger than the upper limit, stretching properties and bending properties deteriorate so that ductility as a low temperature material becomes uneasy. When Mn is larger than the upper limit, the structure becomes coarse, and the ratio of Mn to C is determined to improve the properties of the alloy as mentioned above. N deteriorates low temperature properties and in particular a notch strength ratio at a low temperature, and has an intense influence on deterioration in low temperature properties accompanying strain aging. The purpose of restriction for the notch strength ratio is that tendons in concrete are not fractured by a stress of a normal tensile strength or less when e.g. in a LNG storage tank the internal temperature of the concrete is lowered to about -100°C in 5W10 years after the commencement of storing.
