Title: Treating device for waste polyvinyl chloride by thermal cracking
Inventor: HARADA MOTOFUMI
IPC: C10B53/07
Filed: 1981-04-18
Abstract: PURPOSE:To treat waste PVC with good efficiency by cooling the gas produced by cracking and emitted from a thermal cracking furnace to 250-300 deg.C in the 1st packed bed then cooling the same to about 110 deg.C in the 2nd packed bed and further treating the gas with a neutralizing scrubber. CONSTITUTION:Waste PVC is charged into a muffle furnace 3, and is cracked by heating with a heating means 6, after which it is recracked in a catalyst packed bed 5, whereby the amt. of the heavy oil production in the gas produced by cracking is reduced. Thence, the gas produced by this is supplied to the 1st and 2nd oil separating towers 11, 17 successively, where heavy oil and light oil are separated. These oils are stored in an oil tank 13. Further, the gas produced by cracking passes through a limestone  bed 20 of a neutralizing scrubber 19 wherein the surface of the limestone bed is held wet, thereby causing the hydrogen chloride in the cracked gas to make neutralization reaction with lime. The thermally cracked gas which is removed of oil contents and hydrogen chloride is stored in a gas holder 23, after which it is utilized as fuel for the means 6 through a duct 9.

Title: Liquid-phase epitaxial growth method for semiconductor element
Inventor: IIZUKA YOSHIO
IPC: H01L21/208
Filed: 1978-05-19
Abstract: PURPOSE: To obtain the uniform impurity density for the substrate by froming the impurity introduction aperture provided to the sliding plate sliding on the boat storing the semiconductor substrate into the hole featuring the large and small diameters and thus using the large-diameter hole as the density of the impurity to be introduced decreases.  
     CONSTITUTION: Gap substrate 2 is stored within concavity 3 provided to boat 1, and sliding plate 4 holding solution tank 5 and impurity introducing aperture 6 is stacked on substrate 2. Then Ga solution containing GaP is put into tank 5, and plate 4 is shifted to get wet substrate 2 with solution 7. Aperture 6 is then positioned on substrate 2 by shifting plate 4 to feed in the impurity such as Zn or the like through aperture 6. Then the temperature is lowered down to grow P-type GaP layer on substrate 2 through liquid-phase epitaxial. In such growing device, the aperture provided to sliding plate 24 is composed of the aperture holding plural units of hole 26 of about 1mm and hole 27 of about 3mm each. And the large aperture is used as the introducing impurity density reduces to secure the fixed density for substrate 2.

Title: Facsimile equipment
Inventor: OMACHI MASAHIKO
IPC: H04N1/00
Filed: 1992-02-13
Abstract: PURPOSE:To omit the time calculation that requires the consideration of the time differential. CONSTITUTION:A training is started with reception of a DSC (digital instruction) signal. If the training succeeds, a clock circuit 5 outputs the time data to a character generator CG 4 via a CPU 7. Thus the time data are turned into the characters. The time character data are recorded on the recording paper by a recording part 8 and the CPU 7 performs the control in order to slightly delay a CFR (reception preparatory confirmation) signal. When the character data equivalent are received and recorded, a facsimile equipment 1 completes the communication with reception of an EOP (procedure end) signal and a DCN (circuit cut instruction) signal as long as no MPS (multipage signal) is confirmed. When the MPS is received, the time data are recorded on the recording paper after the success of the training. Then an MCF signal is sent to a terminal and the originals of the 2nd and subsequent pages are received and recorded. These operations are repeated until no MPS is received. Thus the clock of the receiver side is added to the received images and therefore it is possible to omit the time calculation that requires the consideration of the time differential.

IPC: E01C19/34
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To reduce the breakage factors of coil springs and main body components by using the coil springs having such a shape that pitches of coil strands are changed nonuniformly along the longitudinal direction against a load and the deflection quantities of the springs are gradually changed from one end toward the other end. SOLUTION: Coil springs 10 are arranged in an upper space section and a lower space section across a rod end in the leg inner cylinder of a rammer. Each coil spring 10 is wound with a coil strand 13 of a fixed size into a coil shape in a uniform outer diameter size from the lower end 14 to the upper end 15 so that the pitch and pitch angle of the strand 13 are gradually increased from the lower end 14 to the upper end 15 to form the nonuniform-pitch coil spring 10. When a load is applied, the strand 13 is gradually crimped in the longitudinal direction, an effective section as the spring 10 is changed as time elapses, thus the apparent spring constant is gradually increased, and the impact force when the strand 13 is wholly stuck is reduced.

Abstract: PURPOSE:To facilitate an easy manufacture as well as secure the variable focus of convergence, by bending the piezoelectric substance into the direction orthogonal to the scanning direction and furthermore varying the curvature of the bending with use of the high molecular piezoelectric film featuring the flexibility for the piezoelectric substance. CONSTITUTION:Supporter 7, back electrode 8, high molecular piezoelectric film 9 and surface electrode 10 are laminated in that order, and then the flexibility is given to the whole of such laminated substance. At the same time, the laminated substance is bent into the direction orthogonal to the scanning direction, and also electrode 10 is divided into a number of slips A1, A2, A3 and so on. The both ends of the laminated substance in the bent direction are clamped with holder frames 11 and 12 for fixture. That is, holder 11 is fixed properly; while holder 12 is fixed via one end of solenoid actuator 15 each. And actuator 15 is shifted toward arrow B-C through excitation of driving coil 17. As a result, the curvature of the transducer is varied, thus changing the converging position of the sound wave in the direction which is orthogonal to the scanning direction.

Title: Multi-language conversion processing system for data processor
Inventor: NAGASHIMA HIRONOBU
IPC: G06F17/28
Filed: 1989-03-13
Abstract: PURPOSE:To easily and properly cope with addition of new data by treating the omission data as the corresponding data if a selected language conversion table has no its corresponding data when the data to be converted is converted into its corresponding data. CONSTITUTION:A multi-language conversion module 17 called out by a multi- language conversion mechanism 18 retrieves a key word module 1 out of the set language conversion tables 13-1 - 13-n to detect the order of the designated key word. At the same time, the module 17 retrieves a data module 2 based on the detected information and specifies the corresponding data to send this back to the mechanism 18 as the answer data. If the key word received at that time point is not contained in the module 1, the omission data 14 like a blank, for example, is sent back as the corresponding data. This data is shown on a display screen. Thus a new key word is easily added to its original position.

Title: Speaker reproducing system
Inventor: IRUMANO TAKAO
IPC: H04R3/02
Filed: 1979-05-15
Abstract: PURPOSE:To secure the flat sound pressure frequency characteristics at the hearing point by selecting properly the shape and the size of the speaker box and the attaching position of the speaker. CONSTITUTION:The band cut-off filter is connected to the front step of the speaker 7, and at the same time the band pass filter is connected to the front step of speaker 8 each. Thus the dip is not caused by the reflected waves on the floor surface and at the hearing point. In case some dip is caused to the sound pressure frequency characteristics owing to the interference produced by the path difference between the rear wall reflected wave which is radiated from speaker 7 and reaches the hearing point after reflected on rear wall 9 of speaker box 5 and the direct wave which is radiated from speaker 7 and reaches directly the hearing point, the shape and the size of box 5 are determined so that the path difference between the rear wall reflected wave and the direct wave may be almost equal to that between the floor surface reflected wave and the direct wave. And speaker 8 is attached to such area that no dip may occur even with th frequency to cause the dip. As a result, no dip is produced by the rear wall reflected wave and in terms of the sound pressure frequency characteristics.
