Title: Semiconductor integrated circuit
Inventor: ARAKI TATSU
IPC: H01L29/73
Filed: 1984-12-05
Abstract: PURPOSE:To form a capacitor having large capacitance while obtaining a semiconductor circuit the area of which is reduced, by shaping the capacitor and an NPN or PNP transistor into one isolation wall. CONSTITUTION:When the forward bias of a junction between a collector and a base in an NPN transistor 15 is prevented in a semiconductor integrated circuit, N<+> diffusion layers 24 and an N type epitaxial layer 20 have the same potential, and two capacitors of a capacitor 14a by both diffusion layers 24 and a capacitor 14b by a P type diffusion layer 23 and the N type epitaxial layer 20 are formed. The two capacitors 14a, 14b are connected in parallel, and capacitance per a unit area synthesizing these capacitors is increased to twice or more. The N<+> diffusion layers 24 are connected electrically to the N type epitaxial layer 20, and the P type diffusion layer 23 functions as a base in the NPN transistor. Accordingly, the NPN transistor 15 and the capacitors 14a, 14b are shaped in one confined isolation walls 21, 22, thus extremely reducing the occupying areas of several element consisting of a semiconductor.

Title: Intermediate potential power circuit
Inventor: SUGIBAYASHI NAOHIKO
IPC: H03F1/00
Filed: 1988-10-13
Abstract: PURPOSE:To suppress the variance of an intermediate potential and at the same time to increase the current ability up to about four times as much as the conventional value to set the potential of a node point at its original level again by incorporating a pair of MOS transistors MOS using the node point driven at an intermediate potential as the gate input into and intermediate potential generating part. CONSTITUTION:A node point 17 is driven at the same potential as that of a node point 12 by means of a TR 4 using a node point 10 as a gate and a TR 5 using a node point 11 as a gate. If the TR 6, 7, 13 and 14 have the current abilities which are sufficiently high compared with the resistances 8 and 9, the point 12 is set at 1/2 VCC and not dependent on the threshold voltages VTP and VTN of the TR. This is due to a fact that both node points 15 and 16 are set at (1/2.VCC-VTP) and (1/2.VCC-VTN) with VTP>VTN and VTN>VTP respectively. When the potential of the point 17 varies by DELTAV by some reason, the potential of the point 12 varies by about -DELTAV. Therefore the driving ability of the point 17 is set at 4beta1DELTAV<2> and 4beta2DELTAV<2>.

Title: Water purifying material and bath water purifying apparatus using the same
Inventor: SEKI JUNICHIRO
IPC: C02F1/28
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To promote the adsorption of suspended particles to a purifying material and to enable the prevention of clouding even in an initial period of use by coating the surface of active carbon with a polymer having a negative charge and coating the coat with a polymer having a positive charge to form double polymer aggregation films. SOLUTION: A purifying material used in a bath water purifying apparatus is formed by coating the surface of active carbon 5 with a polymer 6 such as polyaluminum chloride having a negative charge and coating the coat with a polymer 7 such as polyacrylamide having a positive charge. In this process, since suspended particles which cause clouding are in many cases charged negatively, its outside is coated with a polymer aggregation film 7 charged positively, and the mass of the film 7 is made greater than that of the inside polymer film 6 so that the suspended particles can be adsorbed easily on the purifying material. By the double coating with polymers, a polymer aggregation film can be stuck strongly to the surface of active carbon 5.

Title: Power source control system for image display device
Inventor: HAGIWARA YOSHIHIRO
IPC: G06F3/147
Filed: 1989-10-04
Abstract: PURPOSE:To eliminate unnecessary power consumption and to prevent a cathode- ray tube from being burnt by turning off the power source of the image display device unless an image display changes for a certain time. CONSTITUTION:When a central processing part 3 writes data in an image display data storage memory part 4, a memory access monitor part 5 recognizes this processing and outputs an access recognition signal 13 to a power source control part 6. The power source control part 6 counts up repeatedly with a clock signal 14 and outputs a power-OFF signal to the image display device power source 7 when the counted value reaches a certain proper numeral. Then, when the memory access monitor part 5 outputs the access recognition signal 13 to the power source control part 6, the counted value is reset. Namely, the power source of the image display device 8 is turned off unless the display contents of the image display device 8 changes for the certain time, and turned on when there is a change again. Consequently, unnecessary power consumption is prevented.
