Title: Removing method of photoneutron effect in measuring device of boric acid concentration
Inventor: TOMINAGA HIROSHI
IPC: G21C17/02
Filed: 1989-05-31
Abstract: PURPOSE:To simplify a correction treatment by measuring a gamma-ray dose generated from an impurity of a heavy water, by converting it into an amount of photoneutron (Iph) using a specific equation and by subtracting the Iph from a count number at a neutron counter tube. CONSTITUTION:For example, when an excess boron concentration in a heavy water (a density; 1.1g/cm<3>) is 150ppm, a gamma ray absorption per 1cm does not exceed 6 millionth or so, and is almost negligible. As a result, a measured value Igamma of the gamma ray and a photoneutron Iph measured by a neutron counter tube can be expressed as Iph=N(chi)Igamma, where N(chi) is a constant depending on <10>B concentration and a reason why the constant N is made to be a function of the <10>B concentration is, because an absorption effect of the photo neutron, too, by the B is considered. Thermal neutrons from a neutron source can be solely calculated through an correction that the Iph is subtracted from a count number measure by a counter 4, and the <10>B concentration can be also obtained.

Title: Semiconductor memory
Inventor: EZAKI TAKEYA
IPC: G11C11/401
Filed: 1986-06-12
Abstract: PURPOSE:To enable data to be stored for a long time without any power supply by a method wherein insulating films of a dynamic memory (DRAM) are provided with an electron arresting function. CONSTITUTION:The potentials of a diffused layer 5 and a cell plate 8 are respectively as Vs and Vp. With a DRAM entering into the state of suspension, the potential Vp is raised up to the positive writing-in potential for several miliseconds. When Vs='O' level, electrons are injected from the layer 5 to a two-layered insulating film 76 by tunnel effect. When Vs='1' level, if the potential Vp is set up to provide (Vp-Vs) with the value subjected to not tunnel effect, the electrons are not injected into the twolayered film 76. Thus, the electrons are stored in insulating films corresponding to the potential of layer 5,i.e., the data of cell. The electrons in the insulating films are stored for a long time even if they are not impressed with any outer power supply. Through these procedures, the data can be stored for a long time even if the power supply is in the state of suspension.

Title: Semiconductor laser device
Inventor: OSHIMA SHIGERU
IPC: H01S5/0687
Filed: 1990-05-25
Abstract: PURPOSE:To facilitate handling, realize high sesitivity, and stabilize wavelength for a long period, by synchronously detecting the detected signal of a photo detector and an AC signal applied to a pair of electrodes of a Fabry-perot resonator, and sending a wavelength control signal to a semiconductor laser, so as to reduce an error signal. CONSTITUTION:AC signal V1 is applied to electrodes 194, 195, and electric field Ex is generated in the X-axis direction, thereby lineally polarizing incident light S4 in the X-axis direction or the Y-axis direction. As a result, the incident laser light S4 to the Fabry-Perot resonator 19 is modulated so as to correspond with the Fabry-Perot resonant wavelength by the electrooptic effect r11 of quartz. A synchronous detector 27 obtains a product of the output v2 of a second photo detector 21 with reference to the AC input V1, and eliminates high frequency components, thereby performing synchronous detection. The detected result is outputted as an error signal to a feedback controller 28. The controller 28 multiples the input error signal by a specified feedback gain, and according to the value, changes the injection current for determining the oscillation wavelength of the semiconductor laser 11 and controls the error signal to be zero.

Title: Twisted printed wiring
Inventor: TAKASHIMA NORIHEI
IPC: H05K9/00
Filed: 1989-05-30
Abstract: PURPOSE:To improve deterioration of high band transmission characteristics by alternately connecting upper and lower layers of upper and lower layer signal line patterns of a printed board via conductive holes to form two continued signal lines, and intersecting the upper and lower layer patterns of the signal lines via an intermediate insulating layer. CONSTITUTION:Upper layer signal line patterns 2, 3, 4 formed on the front surface of a board 1 and lower layer signal line patterns 5, 6, 7 formed similarly on the rear surface of the board are formed. The patterns 2, 3, 4 and 5, 6, 7 are so connected as to alternately arrange the upper and lower layers, thereby forming continued two signal lines A, B. Thus, since the two signal lines are so formed that the upper and lower layer patterns are crossed through the insulating layer and twisted, even if the signal line is long, an electrostatic capacity between the signal lines is extremely small, and magnetic fields are cancelled to each other. Accordingly, since a static induction, a magnetic induction are eliminated to obviate pickup of an external noise signal and unnecessary external radiation, high band transmission characteristics are remarkably improved.

Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To easily and inexpensively make city water softened water by connecting a water softener to the downstream from an opening and closing valve of a water faucet and upstream from a water discharge port. SOLUTION: A water softener 1 has a built-in cation exchange resin cylinder 2 filled with cation exchange resin 3 and is installed on the downstream from a valve 18 which is an opening and closing valve and on the upstream from a water discharge port 19. When the valve 18 is opened, hot water or water enters the bottom of the water softener 1 from an inlet part 4 through a hot water output pipe 20, and it becomes an upward flow to pass through the cation exchange resin 3, so that it becomes softened water. The softened water is passed from an outlet part 5 through a water discharge pipe 23 to be discharged from a water discharge port 19. In restoring the exchange capability of the cation exchange resin 3, a valve 27 is closed to close a water channel to the hot water output pipe 20, and valves 25, 26 are opened to throw in salt or salt water through a pore 21.  The softened water from which hardness component is removed prevents soap scum from adhering to the kitchen and sanitary space parts to heighten the cleansing capability of soap detergent. The softener 1 can be installed at a low cost in a general home, and as the cation exchange resin 3 can be regenerated by salt, the maintenance cost can be held down.

Title: Sheet for stabilizing basal bottom of underwater structure
Inventor: YUKIMOTO MASASHI
IPC: E02B3/12
Filed: 1982-08-09
Abstract: PURPOSE:To prevent the uneven settlement of an underwater structure by a method in which each end of plural bands wound around a perforated tube is fixed to the free end of a flexible sheet laid on the basal bottom of the underwater structure in such a way as to prevent the scouring of the substrate ground. CONSTITUTION:In the free end portion of a sheet body 1 projected from the peripheral edge of the basal bottom of an underwater structure, soil and sand go through holes 2a from the lower part into a perforated tube 2 and deposit to cause the perforated tube 2 to settle. As the settlement proceeds, soil and sand in the surrounding area go from the upper part into the tube 2, and thereby the tube 2 with soil and sand is buried in the ground and the soil and sand in the tube 2 are led to the soil and sand of the ground. An anchor integrated with the ground under water is thus formed. The end of the sheet body 1 connected through a flexible belt 3 to the anchor is fixed to the ground under water. The rocking movement of the free end of the sheet body 1 by tidal wave and water current can therefore be prevented and the uneven settlement of the structure caused by the scouring of the ground under water can thus be prevented.
