Title: Idle speed controller for internal-combustion engine
Inventor: ONO FUJIO
IPC: F02D41/22
Filed: 1984-07-25
Abstract: PURPOSE:To prevent the abnormal increase of the idle revolution speed by cutting-off a conduction circuit to an idle speed control valve and allowing said valve to be perfectly closed by a return spring built-in when an anomaly is generated in the pulse signals for controlling the idle speed control valve. CONSTITUTION:When an engine is in idle operation, a controller 6 sets an aimed revolution speed on the basis of the engine cooling temperature outputted from a temperature sensor 4. The duty ratio of the pulse signals supplied into the bases of the transistors T1 and T2 from the controller 6 is set so that the idle revolution speed of the engine accords with the aimed revolution speed, and an idle speed control valve 1 is opening/closing-operated according to the set ratio. While, when an anomaly is generated in the pulse signals outputted from the controller 6, an FF8 as frequency detecting means turns-OFF the transistor T0 as conduction control means. Therefore, the control valve 1 is perfectly closed by a return spring built-in.

Filed: 1980-10-31
Abstract: PURPOSE: To prepare a para-substituted halogenated benzene, in high selectivity, by the vapor-phase halogenation of a benzene compound with a halogenating agent using a zeolite having a specific average pore size as a catalyst.  
     CONSTITUTION: A para-substituted halogenated benzene compound, e.g. p-dichlorobenzene, is prepared by the vapor-phase halogenation of benzene or a benzene derivative with a halogenating agent, e.g. elemental halogen such as Cl 2 , Br 2 , etc. in the presence of a zeolite catalyst at a temperature which allows the existence of a sufficient amount of the benzene compound as vapor phase. The zeolite catalyst is either a zeolite having an average pore diameter of 5.0W13Å, or a zeolite having an average pore diameter of 5.0W13Å and carrying a halogenating catalyst.  
     EFFECT: Since the halogenation is carried out under vapor phase, the lowering of the catalyst activity by the by-produced hydrogen halide can be suppressed, and the activity and the selectivity of the catalyst can be maintained at high levels for a long time.

Abstract: PURPOSE:To ensure desired viscous resistance through sufficient supply of fluid to a fluid chamber by a method wherein a passage for supply of fluid communicated with a fluid chamber on an outer periphery through a window hole to contain a resilient member is formed in the intermediate part in a radial direction of a driven member. CONSTITUTION:When torque is inputted to a first fly wheel 2 from a member on the engine side, torque is transmitted to a second member 6 to a first member through resilient members 12a and 12b to rotate a second fly wheel. When twist vibration is transmitted and relative rotation is generated between a first fly wheel 2 and a second fly wheels, the resilient members 12a and 12b repeat expansion and contraction and a viscous damping part causes the generation of viscous resistance to damp contraction or twist vibration. In this case, viscous fluid leaks from a fluid chamber 7a and viscous fluid is supplied in the fluid chamber 7 through the window hole 6b of the second member 6 by means of a passage 6d for supplying fluid. In which case, the window hole 6b of the second member 6 is a place where a most amount of viscous fluid is contained and a sufficient amount of viscous fluid is supplied in the fluid chamber 7a and a desired viscous resistance force is generated.

Abstract: PURPOSE:To improve the performance of transistors by ion-implanting boron difluoride into a silicon substrate through a thermal oxide film, and activating the ion implantation regions by heating them with light exposure, thereby forming P-type regions. CONSTITUTION:With a resist pattern 6 and a field oxide film 2 as a mask, boron difluoride is selectively ion-implanted through a gate oxide film 5 into the substrate 1 surface in a region where an element is to be formed. After removing the pattern 6, the oxide film on the implantation regions 108, 109 is removed to expose the upper surface of the regions 108, 109. The regions 108, 109 are heated and activated by a lamp anneal method, thereby forming a shallow P<+> type source region 8 and a P<+> type drain region 9. Whereupon, the surface level due to fluorine ions greatly reduces, so that the surface leakage at the source-drain junction greatly reduces. With this, the improvement of the performance of transistors is accomplished.

Abstract: PURPOSE:To obtain color filters having good smoothness of filter surfaces by providing the entire surface including transparent colored layers formed on a transparent substrate with a UV curing resin layer, selectively exposing the parts corresponding to the inter-pixel parts of this UV curing resin layer and subjecting the layer to a heat treatment. CONSTITUTION:The transparent colored layer 2 (R, G, B) of three colors; red, green and blue, is formed to a pixel pattern shape by a printing method on the transparent substrate 1. Next, the UV curing resin layer 3 is formed over the entire surface inclusive of the transparent colored layer 2 and is irradiated with UV rays, by which the parts corresponding to the interpixel parts of the UV curing resin layer 3 are selectively exposed; in succession, the resin layer is subjected to the heat treatment. As a result, the parts 3b corresponding to the inter-pixel parts of this UV curing resin layer 3 are unexposed and are, therefore, larger in thermal shrinkage than the exposed parts 3a corresponding to the inter-pixel parts and consequently, the difference between the projecting parts and recessed parts on the surface of this UV curing resin layer 3 is reduced and the smoothness of the surface is improved.

Abstract: PURPOSE:To secure a storage coaler capable of loading and unloading at will, by setting up a coal stowage opening at each side tank top of a ship retired from coal/oil carrier service as well as the plural number of openings beneath a longitudinal bulkhead between the side tank and a center tank, while concreting on a bottom stiffener. CONSTITUTION:The stowage of coal into a coaler 1 is carried out in the following procedures that it is cast in from a coal carrier 17 through the upper part of a hatch 5 with a traveling crane 9 and thereby a center tank 5 is filled up inside with coal. On the other hand, stowage into a side tank 3 is as follows tht first each hopper 14 of the crane 9 is adjusted to a coal stowage port 13 and then coal is taken in each side tank 3 from the hoppers 14. Next, when coal is taken out from the coaler 1 to the coal carrier 17, first it is carried out by means of a crab 10 from a center tank 2 and at that point when unloading is drawing near to an end, a heap of coal is collapsed down, through each opening 8, from the tank 3 but when residual quantities inside the tank 3 work out to a coal amount 16, the crumbling stops. Thereupon a sidehill of coal in piles is leveled down from the foot whereby coal inside the tank 3 is put together and taken out by the crab 10.

Title: Fine voltage measurement system
Inventor: HASHIZUME KEN
IPC: G01R19/155
Filed: 1983-08-24
Abstract: PURPOSE:To eliminate a common mode error by holding the difference between one input voltage to an operational amplifier and each source voltage invariably constant even when the one input voltage varies. CONSTITUTION:Relay contacts RY1 and RY2 are made and the difference voltage between inputs Vin1 and Vin2 is measured. A source voltage is generated from one voltage Vin2 between two input terminals and supplied to the power source of the amplifier of a measurement system to prevent a large common mode voltage from being developed at each amplifier. Specially, the operational amplifier is reguired to have small noise. Resistance R11 and R12 should be reduced in impedance as much as possible, so the operational amplifier 1 uses a voltage follower. The drift and DC offset of the amplifier 12 are compensated by an offset removing D/A converter 22. Operational amplifiers 12-14 amplify the voltage between voltages Vin1 and Vin2 by >=1,000 to obtain such a voltage level that there is no problem as to noise.
