Title: Integrated circuit
Inventor: UENO MASAYUKI
IPC: H01L23/52
Filed: 1992-07-16
Abstract: PURPOSE:To enable the signals of a certain circuit of an integrated circuit to be less induced as noises in the other circuits of the integrated circuit. CONSTITUTION:Wirings PL1a, PL2a, AL1a, AL2a,... are of multilayered structure composed of wiring layers and so laid out into patterns as to isolate a digital part as a noise source from an analog part as a noise limiter. The wiring layers are connected to one another through contacts and to a constant potential section 5 with a constant potential wiring 3. The constant potential section 5 is, for instance, a power supply wire or a grounding wire. By this setup, an integrated circuit can be lessened in electromagnetic induction, electrostatic induction, and radiation of electromagnetic waves through wirings of multilayered structure, and consequently the integrated circuit can be reduced in noise induction.

Title: Self-excited communication direct current breaker
Inventor: ITO HIROMOTO
IPC: H01H33/59
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a small direct current breaker and improve the shutoff function by eliminating reactor of a commutator, simplify the structure of a breaker, lower the electric resistance of a commutating circuit, and heighten the magnification of electric current. SOLUTION: When arc contacts of a breaker 11 are parted and an electric current shutoff process is started, even if no reactor is installed in a commutating circuit, an arc is generated and since the arc itself has inductance, oscillation is started attributed to mutual functions of the arc and a capacitor 12. Various disturbances appear as slight fluctuations of the electric current and in the case the circuit condition is in an unstable region, the disturbances grow and the vibration is enlarged and current zero is obtained. In this way, by connecting a capacitor 12 in prescribed conditions with the commutating circuit, the vibration is enlarged and the electric current can be shut. Moreover, by connecting a surge absorber 14 in parallel with the capacitor 12, a surge absorber d.c. current breaker can be provided.

IPC: G03G15/09
Filed: 1986-08-13
Abstract: PURPOSE:To miniaturize an entire device and to improve operability, durability and image stability in terms of a hybrid developing device by setting a gap amount between a developer supporting member and a toner supply means lower than the gap amount among the developer supporting member, a latent image carrier and a toner recovery means.

Title: Measuring instrument for unevenness quantity in road crossing direction and condition of road surface measuring instrument with same
Inventor: INAGAKI TATSUOKI
IPC: G01B11/30
Filed: 1989-07-25
Abstract: PURPOSE:To accurately measure the unevenness quantity of a road in its crossing direction by providing a ground sensor atop of respective piston rods of cylinders mounted on a measuring vehicle, and coupling pulse encoders provided at parts of the cylinders with the piston rods. CONSTITUTION:The piston rods 6 project to the road surface with air from an air compressor 12 and the ground sensor 7 atop the rods 6 contact the road surface. The respective ground sensors 7 differ partially in the height of the contacted road surface owing to a rut dip which is generated with secular change, so the piston rods 6 differ in projection length. A pulse encoder 8 rotates through a cord 9 as each rod 6 projects, and the projection length of the rod 6 is sent from the pulse encoder 8 to a computer, so that the unevenness quantity of the rod surface in one cross-directional line can be measured from the projection length of the rod 6. This measuring operation is performed intermittently at constant-distance intervals during the travel of the measuring vehicle 10.

Filed: 1988-08-01
Abstract: PURPOSE:To maintain a slide gate value in a closed position over a long period of time by coating the outer peripheries of the refractory plates of stationary members and refractory plates of sliding members respectively with refractory heat resistant materials. CONSTITUTION:A sliding frame body 48 is slide by the forward and backward moving means of a hydraulic cylinder 52, etc., to communicate respective through-holes 43, 63, 73, by which a molten metal can be taken out of a container via the slide gate valve. The slide gate valve is closed by moving the sliding frame body 48 to the positions where the respective through-holes 43, 63, 73 are not communicated. Since the outer peripheries of the respective refractory plates 42, 63, 73 are coated with the refractory heat insulating materials 44, 64, 74, the heat insulating effect in the slide gate valve can be enhanced. The slide gate valve is thus maintained in the closed position over a long period of time.
