IPC: C02F1/52
Filed: 1986-06-13
Abstract: PURPOSE:To enhance floc forming efficiency, by treating a flocculant to be added to water to be treated with water in a flocculant treatment tank to form flocs and adding said flocs to the water to be treated in a stirring tank. CONSTITUTION:Raw water is made to flow according to a usual treatment method and a flocculant treatment apparatus 5 is operated. The flow rate of well water is measured and the pumping-up quantity of a pump 7 is controlled so that the flocculant injected in a rapid stirring tank 2 is adjusted to predetermined quantity. The turbidity, temp. and alkalinity of well water are measured and the injection quantities of an acid type flocculant and a polymer flocculant to well water are determined on the basis of the measured values and said flocculants are dispersed by a line mixer 13. Then, the well water is sent to the stirring chamber 20b of a flocculant treatment tank 20 and sludge is injected into said chamber 20a so as to be set to predetermined concn. to perform stirring. Subsequently, a neutralizing agent is injected into a stirring chamber 20b under stirring so as to make the treated water neutral to form floc growing to a flocculation nucleus.

Title: Dynamic exposure tester for waterproof material
Inventor: ONO TADASHI
IPC: G01N17/00
Filed: 1980-09-30
Abstract: PURPOSE:To enable an extensive and continuous extraction of expansion factor applied on a waterproof material gaining an unequally distributed moment by connecting two pieces of joint component material at three points with pins. CONSTITUTION:Expansion members 1 and 2 are arranged horizontally on a member 9 buried into a concrete foundation. When the two expansion members 1 and 2 are thermally expanded, a relative displacement is generated therebetween and according to it, left pin-connected sections 7 and 8 thereof are opened or closed with the right pin connection 5 as a fulcrum. Consequently, an unequal distributed moment develops between the members 3 and 4 with the movement varying along the length of the joint 6. This facilitates the capture of the critical point in the fatigue resistance of sealing material and waterproof material.

IPC: G06T1/00
Filed: 1987-05-30
Abstract: PURPOSE:To obtain inter-gradation conversion coefficients corresponding to an image and its background image and to simplify a background vanishing operation, by separating a partial background image from the image and extracting a proper number of aggregates of image elements out of said partial image to analyze the gradation of the corresponding image element via the extracted aggregates of image elements.

A threshold value calculating circuit 14 obtains a threshold value to separate a partial background image from the image A and inputs this threshold value to a comparator 16. At the same time, a random number produced from a random number generating circuit 10 is sent to an address generating circuit 9 for generation of the address of the memory 4. Then the image elements of the image A are extracted at random. The gradation (ga) of the extracted image element is sent to the comparator 16 and a background part if decided is stored in a regression analyzing data buffer 17. At the same time, the gradation (gb) of the image element of the image B is also stored in the buffer 17.

Title: Continuous casting device for steel plate
Inventor: FUKASE HISAHIKO
IPC: B22D11/06
Filed: 1983-07-28
Abstract: PURPOSE:To provide a titled device which prevents effectively the generation of a ripped surface on the surface of a steel plate by providing a pouring port so as to be submerged in the well to be formed between cooling rolls and the end walls at the end face of the rolls and regulating the range where a molten steel strikes directly against the melt surface in the stage of pouring the molten steel. CONSTITUTION:Two sheets of partition plates 11, 11 formed of refractories are provided in parallel apart at an adequate spacing from each other in the central part of the well 10 between cooling rolls 1, 1 and apart from the rolls 1. The plates 11 extend over the entire length of the rolls 1 along the axial direction thereof and the bottom end edges are dipped in the well 10 so as to be submerged therein thereby forming a pouring port to accept the molten steel flow 2 poured therein. The molten steel flow admitted onto the well 10 forms a wave on the melt surface when said flow strikes against the melt surface. However all the flow 2 falls between the plates 11 and 11 and therefore the formed wave is blocked by the plates 11, 11 and is prevented from propagating to the roll 1 side. As a result the rippled surface on the steel plate occurring in the ripples generated at the verge in contact with the roll 1 surface is decreased as far as possible.

Title: Digital type combustion control
Inventor: NAKAGAWA SUMIO
IPC: F23N5/20
Filed: 1978-11-08
Abstract: PURPOSE: To prevent the misoperation of the logic control circuit caused by noise entering the input signal of the said logic control circuit in a digital type combustion controlling device which controls combustor such as hot water boiler.  
     CONSTITUTION: When noise N 1  produced from solenoid relay R 3  and noise N 2  produced from discharge pulse IG enter the input signal e, the timings of noises N 1  and N 2  have phasial deviations of T 0  and T 1 , respectively, from the input signal read timing b 1 , so that the signal q input to the logic control circuit 1 remains free of influence by noises N 1  and N 2  and proves to be a normal input signal. When ignition is effected by discharge pulse IG and the signal e becomes "zero", the ignition signal e is written by the rise-up signal b 1  of the clock pulse and solenoid relay R 3  is de-energized by the fall-down signal b 2 . Accordingly, the input signal q to the logic control circuit remains free of influence by noise N 3  produced when solenoid relay R 3  is de-energized.

Filed: 1993-05-14
Abstract: PURPOSE:To form a sufficient surge protection element having simple structure in a semiconductor device where elements are isolated through a dielectric isolation layer. CONSTITUTION:In the structural cross-section of a protective element where the elements are isolate through a dielectric layer 5, i.e., a Zener diode having npn transistor structure, when a surge is transmitted on a line 7 to apply a high voltage to an n-diffusion layer 1, a protective function is actuated with a Zener voltage determined by the diffusion density of a diode comprising an emitter region 1 and a base region 2 thus short-circuiting the high voltage. In this regard, the high voltage is applied not applied to the dielectric layer 5 but applied to a pn junction. Consequently, the parasitic capacitance is not formed even if the semiconductor substrate 6 is grounded and thereby no charging current flow thus protecting the dielectic layer. This structure prevent intrusion of high voltage into the interior thus ensuring the surge protection for the interior of the device.
