Title: Protective circuit for semiconductor device
Inventor: TSUBOTA TOSHIO
IPC: H01L29/78
Filed: 1995-06-15
Abstract: PURPOSE: To provide a high-performance ESD protective circuit by which a turn-off voltage VT is lowered and which prevents a malfunction due to a critical OFF-state voltage build-up rate dv/dt. CONSTITUTION: A p<+> well region 22 is formed around an n-well region 14, and a turn-on voltage VT which is determined by the junction of the n-well region 14 to the p<+> region 22 can be set to be low. In addition, since a parasitic base resistance can be reduced effectively due to the p<+> well region 22, it is possible to prevent a parasitic bipolar transistor from being turned off carelessly.

Title: Flow tripper combined with spacer deflecting part
Inventor: ERITSUKU BAATEIRU YOHANSON
IPC: G21C3/322
Filed: 1989-06-13
Abstract: PURPOSE: To improve cooling of a fuel rod by forming a float ripper on the inner wall in an upper two-phase area, and disposing it immediately under a spacer. CONSTITUTION: Approximately four or five spacers 29 are disposed in the upper two-phase area of a fuel bundle. A float ripper 62 is formed on a wall 70. And in a water layer 72 water is turned away to a two-phase mixing area from the wall 70 on the upper edge of the float ripper 62. Thereby the wave height of a flow liquid film increases, accordingly, much liquid is transferred to the surface of a fuel rod. The liquid film is sufficiently disturbed with the float ripper, collides with a skirt and the inside of a turning-away part 64, and inward moves toward the fuel rod 26. Thereby since thickness of the liquid film contacted on the fuel rod increases and cooling of the fuel rod is improved, output ability of a fuel assembly is enhanced.

Abstract: PURPOSE:To enable to perform the treatment to separate and extract plural fruits at high speed with simple constitution by inputting the variable density image information removing in advance the variable density image information in the zone excepting the object fruit color to an edge image detecting means. CONSTITUTION:A color separating circuit 3 separates and extracts the bivalent color image information F1 in the zone corresponding to an object fruit color from the color image information among the image pickedup image information S0 by a color video camera 1. An edge image detecting means separates and extracts the bivalent edge information corresponding to the part where its lightness variation is larger than the variable density image information Y among the informations S0, then, with the information F1 as a switch control signal, controls the switching of a gate circuit 4 to extract the variable density image information S1 in the zone corresponding to the fruit color and inputs the information S1 to the edge image detecting means. Since therefore this information S1 does not include the unnecessary information excepting the object fruit a high speed processing is enabled because of the processing informa tion quantity being less.

IPC: G01C21/00
Filed: 1992-06-09
Abstract: PURPOSE:To shorten the time required to estimate the reachable range within the specific time by analyzing a road network. CONSTITUTION:The road is ranked by national highway roads, prefectural highway roads, and general roads, and the speed coefficient and the position of each intersection are stored in a road network definition part 1.

Said signals are then outputted, via an interrupt generating circuit 3 provided with an encoder 3-1, gate 3-2, etc., to corresponding low-order bits through a data bus DB2 for low order, and then supplied to the CPU 1. As a result, the need for the signal lines on the data bus every cause of interrupt is eliminated, and accordingly the number of pieces of the signal lines, connectors, etc. are reduced.

Title: Duct type electrostatic precipitator and operating method thereof
Inventor: NAGATA MASAYUKI
IPC: B03C3/74
Filed: 1989-06-12
Abstract: PURPOSE:To prevent the shortening of the life of electrodes and to suppress the degradation in dust collection efficiency by executing electrode cleaning for each of respective flow passages which are independent by each middle duct and controlling and setting the charge voltages of high voltage power sources installed independently to each of these middle ducts to low charges below a spark generating voltage. CONSTITUTION:The power sources 5a to 5d are independently provided in the respective middle ducts A to D and are connected by respective independent wirings to the discharge electrodes 4a to 4d and respective dust precipitating electrodes 3. Electrode cleaning nozzles 9a to 9d and flow rate control valves 8a to 8d are provided above the discharge electrodes 4a to 4d of each of the respective middle ducts A to D. The connection and execution of ordinary dust collection are, therefore, possible in other flow passages as well even during the execution of a spraying in a certain flow passage. The charge in this middle duct is, therefore, required to be kept at the low charge below the spark generation voltage in order to prevent mechanical damages, such as electrode wear, during the execution of the spraying. The dust collecting efficiency is consequently slightly degraded. In the other flow passages, however, the ordinary dust collection of high efficiency is executed and, therefore, the degradation in the dust collecting efficiency over the entire part of the dust 11 is suppressed.

Title: Offset adjusting device of amplifier
Inventor: IGARASHI MICHIAKI
IPC: H03F3/34
Filed: 1981-09-21
Abstract: PURPOSE:To perform offset adjustment easily in a short time by providing a circuit which discriminates and displays whether the offset of an amplifier is within a prescribed limit range. CONSTITUTION:When the output voltage V0 of an amplifier Q1 is greater than V1, the output voltage of a comparator Q2 is at[L]in this case, so a light emitting diode D is turned off. When V0<-V2, a comparator Q3 outputs a voltage[L], so the light emitting diode D is still turned off. In this state, a variable resistor VR1 for offset adjustment added to the amplifier Q1 is adjusted until the light emitting diode D is turned on, and consequently it is confirmed that -V2<=V0<=V1, thus completing the offset adjustment.

Filed: 1989-06-14
Abstract: PURPOSE:To increase a capacity without increasing the number of fundamental cells to be used by a method wherein overlap capacities of a gate-electrode extended part and a source-drain region are connected in parallel and are used as capacities. CONSTITUTION:Gate electrodes 15, 16 of a p-type transistor and gate electrodes 17, 18 of an n-type transistor are extended and installed so as to surround source-drain regions 7P, 7N and peripheral edges of guard bands 9, 10; overlap capacities CL formed between the source-drain regions and the peripheral edge parts of the guard bands 9, 10 are added to overlap capacities C1, C2 formed between a gate-electrode end parts and the source-drain regions of the individual transistors. Consequently, when gate electrodes 15 to 18 are extended and installed at the peripheral edges of the source-drain regions, the overlap capacities of the gate-electrode extended parts and the source-drain regions can be added and used. Thereby, a capacity can be increased without increasing the number of fundamental cells to be used.
