Patent JP-H036031-A (JP)
Title: Charge-coupled device
Inventor: MIKAERU ARUUIN UIRIAMU SUTEKER
IPC: H04N5/372
Filed: 1990-05-21
Abstract: PURPOSE: To reduce a leakage current, i.e., a dark current, by a method wherein an active level is so selected that a depletion layer is generated only on the surface of a semiconductor main body, and the surface parts of a charge transfer channel are alternately turned into depletion layers and inversion layers which can store signal charges on the lower side of an electrode. CONSTITUTION: An active level is so selected that a depletion layer is generated only on the surface of a semiconductor main body. The surface parts of a charge transfer channel which correspond to a series of electrodes during operation are alternately turned into depletion layers and inversion layers which can store signal charges on the lower side the electrodes. In this device, the parts storing charges of the charge transfer channel are permanent periodic inversion layers. That is, the surface part is not turned into the inversion layer, and the period that data are stored in the relative part of a channel is set sufficiently short. Excessive amount of traps are filled with electrons from a valence band, and generation of a dark current can be evaded.  Hence a leakage current (dark current) can be reduced by recombination in the inversion layer, and at the same time, isolation of charge packets can be realized by maintaining a suitable potential difference between electrodes.

IPC: H04N5/217
Filed: 1986-06-03
Abstract: PURPOSE:To prevent a black level from being fluctuated in a D/A conversion output even when an adder/subtractor circuit adds and subtracts by adjusting the pre-blanking level of a pre-blanking addition circuit. CONSTITUTION:The pre-blanking addition circuit 2 adds a pre-blanking signal to a signal from an input terminal 1. The adder/subtractor circuit 5 applies prescribed frame number addition to a video signal and a 1-frame memory circuit 6 stores an integrated 1-frame signal as the result. Then light incident on a camera is shut off and only a fixed pattern noise is inputted, the circuit 5 applies prescribed frame number subtraction to obtain 1-frame video signal obtained by subtracting noise of the same frame number from the integrated signal and the result is stored. In adjusting the level of the pre-blanking added by the pre-blanking addition circuit 2 to set the black level of the video signal to 0 by the conversion of 2's complement form code by an A/D conversion circuit 14, the black level is unchanged even when the adder/subtractor circuit 5 and the 1-frame memory circuit 6 apply addition/subtraction.

Title: Nuclear reactor cooling water sampling device
Inventor: WADA YOICHI
IPC: G21C17/02
Filed: 1994-06-13
Abstract: PURPOSE:To make it possible to measure the concentration of ingredients in reactor water with high precision by spraying it into an evacuated container to lower the temperature and pressure rapidly through adiabatic free expansion. CONSTITUTION:After a valve 6 between a vacuum container 1 and a vacuum pump 7 is closed, a valve 2 on the side of the container l and a valve 2 on the side of the container 1 and a valve 9 on the size of a sampling cup 10 is closed. Then, reactor water is poured into an evacuated measuring pipe by opening a valve 3 on the side of the primary piping, and the valve 3 is closed to measure and take a prescribed quantity of the reactor water into the measuring pipe 4. Subsequently, the valve 2 is opened to blow the reactor water at high temperature and pressure from a reactor water outlet 5 into the container 1. Because of the sharp drop of pressure in this process, the reactor water adiabatically vaporizes and cools itself. This reaction reduces resolution and separation in the piping, and makes it possible to sample the reactor water at high temperature and pressure with a dose and measure the concentration of ingredients in the reactor water with high precision.

IPC: C22C38/58
Filed: 1984-06-25
Abstract: PURPOSE:To obtain a high manganese steel having superior suitability to pickling, undergoing a small extent of dissolution of the base metal during pickling after water toughening, and showing high surface smoothness after pickling by restricting the amounts of Ni, Mo and Cr to specified contents. CONSTITUTION:The composition of a high Mn steel is composed of, by weight, 0.9-1.5% C, <0.8% Si, 10-15% Mn and 0.1-1% Cr as essential components, <0.05% Ni, <0.01% Mo and the balance Fe with inevitable impurities.
