Title: Calculation mechanism of ink jet recording apparatus
Inventor: FUJIKURA SEIJI
IPC: B41J2/175
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To enhance the air venting properties in a recording nozzle by providing a chamber part having a partition wall becoming an obstacle with respect to an ink filow direction formed thereto in a circulating route. SOLUTION: The ink 7 in an ink container 11 is pressurized by an ink supply pump 22 through an ink supply solenoid valve 31 and adjusted to predetermined pressure by a solenoid valve 10 to be supplied to a recording nozzle 2 through an ink jet solenoid valve 33. Since the residual air in the recording nozzle exerts adverse effect on the granulation of ink, sufficient air venting is necessary at a time of the start of the apparatus. Therefore, a large amt. of ink is allowed to flow toward an ink discharge port from the ink supply port of the recording nozzle 2 and it is necessary to apply a sudden change in flow velocity. Then, a circulating solenoid valve 35 is provided in an ink circulating route and the opening and closing thereof is provided.  Since the ink circulating route meets with the ink recovery route just before a negative pressure pump 23, a chamber 1 is provided just before the confluent point and the flow velocity of ink entering from the ink circulating route is made slow before the meeting of the ink circulating route and the ink recovery route.

Filed: 1988-06-29
Abstract: PURPOSE:To remove noise without the reduction of a contrast by using a media window matrix method as a noise removing means in a picture signal. CONSTITUTION:Light from an original picture, after it is converted to an electric signal with a photo-electric converter 10, is converted to a digital signal corresponding to the picture element concentration with an A/D converter 11. The digital signal is accumulated in a frame memory 12 as picture data, an mXn picture element is extracted out of the picture signals accumulated at the frame memory 12 by an arithmetic processor 13, one out of these respective ones is successively selected, and further, after the picture element matrix of an (i) row and a (j) column is set, a media window (MD) operation is executed, the obtained value is replaced to the original picture element value and the new picture element arrangement is executed. Thus, without the reduction of a contrast, the high frequency noise can be removed from the picture signal.

Title: Wall surface structure of block for retaining wall and wall surface structure of concrete retaining wall
Inventor: SUEMATSU DAIKICHI
IPC: E02D29/02
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To inhibit dirt by rainwater flowing down from a drain hole by forming a wall surface section extended from the opening section of the drain hole bored to a wall surface to a lower section to a dirt inhibiting surface in which a concrete texture is dirt-inhibited and treated. SOLUTION: The front of a block A for an L-shaped retaining wall is formed on a wall surface 1, and two drain holes 2, 2 are formed by boring the wall surface 1. Dirt inhibiting surfaces 3 are formed by coating wall surface sections extended from the opening sections of the drain holes 2 to lower sections with a water-repellent agent, and the dirt inhibiting surfaces 3 are formed by extending up to the lower edge of the block A from the opening sections in width slightly wider than the width of the opening sections.  When the concrete retaining wall is constructed by using the block A, rainwater is repelled by the dirt inhibiting surfaces 3 because the flowing-down sections of rainwater from the drain holes 2, wall surface sections elongated from the opening sections of the drain holes 2 to the lower sections, are formed of the dirt inhibiting surfaces, and the dirt of water traces by infiltrating to the wall surface 1 of rainwater containing sewage can be inhibited.

Title: Boiling-water nuclear power plant
Inventor: YAMAGUCHI HIDEKI
IPC: G21F9/02
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To detect the concentration of hydrogen without being affected by the concentration of oxygen and enable operation of a power plant stably by inputting the detected oxygen concentration to a hydrogen and oxygen concentration calculator and correcting the effects of oxygen. SOLUTION: A hydrogen concentration detector 12 samples the exhaust on the side of an exist of an off-gas recombiner 10, it is detected by element of thermal conduction type for detecting the concentration of hydrogen such that the thermal conductivity of hydrogen is higher than those of other gases and the concentration of hydrogen in the exhaust on the downstream side of the recombiner 10 is measured. An oxygen concentration detector 13 branches a sample gas measured by the hydrogen concentration detector 12 and measures the concentration of oxygen with a magnetic oxygen densitometer which utilizes the properties that changes the flow of the gas by the paramagnetism of oxygen. In this case, the hydrogen densitometer indicates an apparent reading if the concentration of oxygen is 40% or higher. Consequently, if the output responding to the concentration of oxygen in this range is deducted from the output of the hydrogen detector 12 and the reading is regarded as that of a densitometer, a reading will not be indicated as the concentration of hydrogen even though the concentration of oxygen becomes 100%.

Title: Method and device for connecting pipes
Inventor: ANDOU YORIO
IPC: B29C65/48
Filed: 1979-12-13
Abstract: PURPOSE:To prevent a bonding agent from running-off to the wall interior of the pipes and guarantee the smoothness of the wall interior surface by a method wherein a body expandable by a fluid is expanded and abutted to an internal surface of the bonded section, thereafter, the expanded body is contracted and withdrawn together with an operating tube after the bonding agent is set when the bonding agent is coated and the pipes are abutted to each other. CONSTITUTION:In case the pipes 1, 2 are connected by a bonding agent, fluid is transferred from a hydraulic pressure controlling means 4 to the expandable body 6 through the operating tube 5 to expand the expandable body 6 into the same size as the inner diameter of the connecting section of the pipes 1, 2 substantially. Thereafter, the expandable body 6 is pressurized by the control means 4 through flexible operating tube 5 to contact it with the connecting section of the pipes 1, 2 closely. After the bonding agent coated between the pipes 1, 2 is hardened, the expanded body is contracted and withdrawn from the end of the pipe by pulling the flexible operating tube. Thus, the bonding agent will never run off into the inner side of the pipes because the pipes and the expanded body are contacted closely and the connecting section of the pipes may be joined smoothly.
