Title: Multiple solenoid valve
Inventor: KITANO TAMIO
IPC: G05D7/01
Filed: 1982-11-13
Abstract: PURPOSE:To provide an independent control of the rate of flow for a certain number of outlets as a group for independent control, by furnishing an elastic flow sheet and cup, forming a communication line for communication between through holes bored in larger and smaller sizes in the cup, and thereby facilitating mounting/demounting of a rate-of-flow control means on the incoming side. CONSTITUTION:A flow sheet 5 has such a construction that a major and a minor through hole 7, 8 are bored in a disc made of an elastic material such as rubber, while a cup 6 is provided with a major and a minor through hole 12, 13 mating with said holes 7, 8, respectively, and a communication line 16 consisting of a gap is formed between these flow sheet 5 and cup 6. When water pressure is low, the through hole 7 is supplied with an ample amount of water from the through hole 12 having larger diameter. The through hole 8 is supplied with water from, besides the through hole 13, the through hole 12 and communication line 16. When the water pressure has risen, the edge of the through hole 7 deflects inward owing to elasticity of the flow sheet 5 to cause lessening of the bore diameter of major holes, whereby the rate of flow is throttled gradually. Thus the amount of water supplied is kept constant regardless of the magnitude of water pressure.

Abstract: PURPOSE:To reduce noise due to acceleration by providing an outer frame made of a synthetic resin member to seal a flat piezoelectric element therein and a synthetic resin in gel state having a prescribed Young's modulus packed in a space between the piezoelectric element and the outer frame. CONSTITUTION:Piezoelectric elements 1a, 1b, a base plate 2, lead wires 3a-3d and part of a cable 4 are molded by a gel 5 made of a synthetic resin and the gel 5 and part of the cable 4 are molded by an outer frame 8 made of a synthetic resin. The Young's modulus of the gel 5 is selected so as to be suitable for attenuating external vibration delivered via the outer frame 8 to a spring resonance system comprising the piezoelectric elements 1a, 1b and the base plate 2. Thus, the resonance frequency of the spring resonance system is lowered more than the operating frequency band and acceleration noise output caused by vibration is suppressed lower by the vibration-preventing effect of the gel 5.

Abstract: PROBLEM TO BE SOLVED: To obtain a long life plasma or beam counter plate by adopting carbon for base material which has a specific grating constant of C-axis showing carbon crystallinity obtained from a peak value of X-ray powder diffraction. SOLUTION: Carbon used for base material can be chosen from artificial carbon, carbon fiber reinforced carbon complex material, etc. However, the base material needs to be carbon of which grating constant of C-axis showing carbon crystallinity obtained from a peak value of X-ray powder diffraction is 0.6708 (monocrystal value of carbon) to 0.6730nm. In the X-ray powder diffraction, using the difference in peak angles of C002 plane in Si powder used as reference sample and carbon powder, the interval of the planes of C002 is measured, which is made the grating constant of C-axis showing carbon crystallinity. The carbon for the base material is produced with filter of natural, artificial carbon, etc., having this crystallinity.

Title: Scanner and image processing unit provided with the scanner
Inventor: FUJIOKA TETSUYA
IPC: H04N1/04
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To provide a scanner that reads an image with a plurality of resolutions, reads a range of resolution being an integer multiple or the reciprocal of an integer multiple of a basic resolution with high accuracy, enhances the accuracy of subscanning for thinning processing in the case of an intermediate resolution and enhances the read image quality. SOLUTION: A width W of subscanning one line in matching with a basic resolution is set equally to a value of (n) (integer) times the moving amount of one step of a stepping motor 2. When the stepping motor is driven, a 3-line CCD 11 is driven at a rate of once per n-steps to read an image with a basic resolution. By choosing the set value (n) of the basic resolution to have divisors, then the reading of the image with the basic resolution and a resolution being an integer multiple of the basic resolution can simply be changed in the case of changing the (n) to set magnification of the subscanning. Since the reading data are based on reading data with the resolution expressed in a simple numerical value, the line thinning at an equal interval can simply be attained and the reading accuracy of the intermediate resolution can be enhanced.

Abstract: PURPOSE:To maintain the flatness of a substrate as well as to prevent the deterioration in preciseness of microscopic working by a method wherein an insulating film of one or more layers having compressive stress is contained in the interlayer insulating film consisting of a high melting point metal silicide layer and other material layer. CONSTITUTION:A metal silicide 108 is insulated from a wiring material Al 111 by the plasma nitride 109 obtained by a CVD method and the interlayer insulating oxide film 110 obtained by a chemical vapor growth method. The tensile stress generated by the formation of the metal silicide layer 108 is alleviated by the compressive stress of the plasma nitride 109.

Title: Cr oscillating circuit
Inventor: DEN KEIICHI
IPC: H03K3/02
Filed: 1988-08-10
Abstract: PURPOSE:To prevent an abnormal oscillating action by setting the threshold of the input part of a second input inverting circuit lower than that of a second negative OR circuit. CONSTITUTION:In a CR oscillating circuit consist of a serial circuit composed of a resistance and a capacitor and a schmidt trigger connected between both edges of a resistance in the serial circuit, the relation of a threshold Vth3 of a second input inverting circuit Q3 and a threshold Vth4 of a second negative OR circuit Q4 is composed so as to become Vth4>Vth3.

Thus, the output of the second negative OR circuit is hard to invert and an abnormal oscillating action is not executed.
