Title: Ccd solid-state image pickup element
Inventor: MORI HIROYUKI
IPC: H04N5/372
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To eliminate the propagation delay of transferred pulses from transfer electrodes in upper layers, and prevent the narrowing of the effective amplitudes of the transferred pulses and the reduction of the quantity of handled charges so as to prevent the lowering of the dynamic range of a CCD solid-state image pickup element by overlapping transfer electrodes upon each other by making the transfer electrodes in upper layers thicker in thickness than those in lower layers. SOLUTION: Transfer electrodes 3 and 4 are formed in such a way that the widths of the electrodes 4 are made narrower than those of the electrodes 3 on pixels in the vertical direction. The reason why the widths of the electrodes 4 are made narrower than those of the electrodes 3 is to prevent the electrodes 4 from projecting or falling off from the electrodes 3. In addition, the film thicknesses of the electrodes 4 are made thicker than those of the electrodes 3 to prevent the drop of the electrical resistance due to the narrowed widths of the electrodes 4 on picture elements in the vertical direction. The propagation delay of transferred pulses can be prevented by reducing the electrical resistances of the transfer electrodes 4.

Title: Electron shower device for ion implanting apparatus
Inventor: MATSUDA SHINTARO
IPC: H01J37/317
Filed: 1986-06-27
Abstract: PURPOSE:To prevent negative electrification by electron and static electricity break down by using a circular paraboloid reflector, which reflects electrons proceeding for target to the opposite direction, as an electron reflector. CONSTITUTION:Thermal electrons are generated by flowing electric current through a metal filament 1b from a power supply 2. These thermal electrons are accelerated toward a circular paraboloid reflector 4b by several hundred volts applied by a bias power supply 3. On collision of these electrons to the reflector 4b, secondary electrons whose energy is ranging from several eV to several is of eV are generated. The circular paraboloid reflector 4b pushes these secondary electrons effectively into an ion beam 6 and the electrons neutralize charges of the ion beam itself. Furthermore, since the reflector reflects the electrons proceeding for target 7 to the opposite direction, electrons 5 with energy do not directly collide with a target 7. Accordingly, positive electrification by the ion beam 6, negative electrification by the electron shower, further static electricity break down on the target 7 can be prevented.

Title: Cyclic code generator and cyclic code generating method
Inventor: KAWASAKI TAKESHI
IPC: H03M13/00
Filed: 1992-06-11
Abstract: PURPOSE:To simplify the circuit configuration by inputting directly an inputted code word to a remainder arithmetic operation means so as to use the circuit in common. CONSTITUTION:A remainder arithmetic operation means 1 calculates a residue of an input code word subjected to change through part of rewrite divided by a generation polynomial. An exclusive OR means 2 takes exclusive OR between a check bit in the changed input code and an output of the remainder arithmetic operation means 1. Then a selection means 3 uses an output of the exclusive OR means 2 as a new check bit of the changed input code word to generate a new code word. That is, a level '1' in the residue obtained in the output of the remainder arithmetic operation means 1 indicates that a check bit at a relevant location is changed through the part of rewrite and then the check bit of this location is inverted by the exclusive OR means 2 to obtain a new check bit. Thus, it is not required to make all of check bit parts of the inputted code word and a code word check section and a code word generating section are formed by a common circuit.

Abstract: PURPOSE:To obtain molding sand having stable characteristics and to produce efficiently a good casting mold by calculating the bulk density of the molding sand charged into a looper hopper to a moisture value of the sand with a microcomputer device, and adding the water of the calculated prescribed amt. to the molding sand in a sand mill. CONSTITUTION:Molding sand S fed out from a feeding out conveyor 25 is stored gradually in a sand weighing hopper 18 until the weight of the stored sand, that is, the output voltage of the 2nd load converter 17 attains the saturation point in a specified range. The voltage is fed to a microcomputer device connected electrically to the 1st load converter 7 for a looper hopper 5, by which device the voltage is calculated to the bulk density of the sand S and further to the moisture value of the sand. A gate cylinder 23 operates to retreat to open a gate plate 24, thus charging the sand S in the hopper 18 into the hopper 5. The plate 24 is then closed and when the sand S accumulates to a prescribed amt. in the hopper 5, the weight thereof is measured with the converter 17 and the amt. of the water to be added in a sand mill 1 is determined by the calculation with the microcomputer device. A gate cylinder 13 operates to retreat to open a looper gate 9, thereby supplying the sand S in the hopper 5 to the mill 1, by which the sand is kneaded under the addition of the prescribed amt. of the water.

Title: Hot water supply interruption control method when adding high temperature hot water in automatic hot water supply bath device
Inventor: YASUSAKA TOSHIO
IPC: F24D17/00
Filed: 1991-06-25
Abstract: PURPOSE:To make it possible to supply hot water at a preset temperature promptly by installing a water control valve to a hot water delivery pipe on an upper stream side from a branch point between a bath tub side and a hot water supply side and a water bypass line which bypasses a heat exchanger and a water control valve to a spot between a water supply pipe and the hot delivery pipe. CONSTITUTION:When adding hot water a water, bypass valve 13 is opened. When a hot water faucet 11 is opened, a hot water confirmation switch 10 is turned on and detects demand for hot water supply. Then, the pressure of gas to be supplied is throttled to a specified value while the opening degree of a water control valve 16 is held as it is. While introducing higher temperature hot water to a bath tub 9, the remaining higher temperature hot water is mixed with supply water, thereby supplying hot water. When it is detected that the detected hot water temperature has dropped to a certain preset temperature, a bath solenoid valve 6 is closed so that the supply of hot water to the bath tub 9 is stopped. The opening degree of the water solenoid valve is increased whereas the percentage of intermediate hot water to supply water is increased, thereby supplying hot water at a proper temperature. Furthermore, when the detected temperature of hot water has dropped to a certain preset value, the water bypass valve 13 is adapted to be closed so as to halt the mixture between supply water and hot water so that the supply gas pressure to a burner may be shifted to proportional control operation.
