Title: Charge coupling device
Inventor: KEI UIIN KARUBIN YANGU
IPC: H01L29/10
Filed: 1989-07-05
Abstract: PURPOSE: To improve the charge transfer efficiency of each cell of a charge-coupled device and, at the same time, to increase the operating speed of the cell, by forming channel potential gradients along two charge transfer directions in each channel region of the cell. CONSTITUTION: The channel potentials at regions below the electrodes 91-93 of cells 1-3 are inclined in the X-direction. Since forces act on charge carrier in channel areas below the electrodes 91-93 in charge transferring directions due to the electric fields generated by the potential inclinations, the X-direction drift speeds of charge increases. The drift speed increases of the charge carriers become significant at or near the terminating point of time of a clock cycle at which the differences between the charge carrier densities of adjacent cells become smaller and the potential gradients become gentle due to a clock signal.  Therefore, small amounts of charge carriers remaining in the cells can be pushed completely to an accepting cell side at or near the terminating point of time of the clock cycle at which the driving forces of the charge carrier are reduced by the electric fields added by the inclined channel potentials. Accordingly, the charge transfer efficiency of each cell of a charge-coupled device can be improved substantially even when the frequency of the clock signal becomes higher.

Title: Manufacture of concrete casing pump
Inventor: SEKIMOTO HISASHI
IPC: F04D29/60
Filed: 1985-08-09
Abstract: PURPOSE:To firmly adhere a casing made of a steel plate to concrete therebelow and to prevent formation of an air reservoir, by a method wherein ordinary concrete is placed up to a height of 10-15cm from the lower part of the casing, and expansion mortar is then placed in the remaining space part. CONSTITUTION:When concrete is placed between a machine building 11 and the lower part of a casing 12 made of a steel plate, ordinary concrete 13 is first placed up to a height of 10-15cm from the lower part cm of the casing 12 made of a steel plate. After floating of breathing water is completed, expansion mortar 14 is placed in a remaining space up to the height of the casing 12. Thus, through an expansion pressure generated during curing of the expansion mortar 14, the mortar 14 is firmly adhered to the casing 12 made of a steel plate, and even if an air reservoir is formed during the initial stage of curing, air in the air reservoir is extruded to the outside through the expansion pressure of the expansion mortar 14. This eliminates a hole for air bleeding and a hole for grout which are heretofore formed in the casing 12 made of a steel plate, and enables sharp reduction of an installation cost.

Title: Correlation type speedometer
Inventor: TAGO KEIICHIRO
IPC: G01P5/22
Filed: 1984-08-23
Abstract: PURPOSE:To enable the responding to the modification state large in the fluctuation signal in a current meter for correlation processing of detection outputs on the upstream and downstream sides, by comparing an input voltage corresponding to the detection signal with a reference voltage to control the voltage division ratio of a voltage divider for detection signals and the reference voltage. CONSTITUTION:A fluid movement detection signal 1a with an upstream side detector 1 is turned to a fluctuation signal U1 with an amplifier 3 or the like and supplied to a multiplier 7 for correlation processing via a delay circuit 5 such as CCD. An input voltage Pa corresponding to the signal U1 is compared with a reference voltage corresponding to an upper limit allowable voltage or the like of the circuit 7 by a comparator 14. Then, when it exceeds the reference voltage, the output of the comparator 14 is inverted to change over the voltage division ratio of a voltage divider 11 while with the inverted output of the comparator 14, the reference voltage gives the lower limit allowable voltage of the multiplier 7. Thus, the fluctuation signal to the circuit 7 will be held in an allowable range in the voltage. The same can be done on the downstream side and this enables the responding of the modification state large in the fluctuation signal thereby preventing possible erroneous measurement.

Abstract: PURPOSE:To monitor the reliability of oxide for all wafers after finishing the diffusion process by shortening the measuring time required for estimating the lifetime of oxide significantly without lowering the estimation accuracy or increasing the cost. CONSTITUTION:Dependency of the density J of current flowing through an oxide on the field strength E is measured to obtain a Fowler-Nordheim plot. An estimated value of current density J is then determined at the maximum field strength during actual use based on the linear relationship of the plot.
