Title: Mold structure for molding synthetic resin tube
Inventor: NISHIDA SHOZO
IPC: B29C45/00
Filed: 1990-02-03
Abstract: PURPOSE:To obtain a mold structure for molding a synthetic resin tube capable of tube fixation in which an unevenness of the join parts does not appear utterly in the flange and thus leakage never occurs therein by shifting either one of paired molds for placing two partially tubular bodies into contact with each other, and secondary-injecting a fusing composing synthetic resin to the partially tubular bodies at the groove joint line in which the two partially tubular bodies come into contact with each other, for joining the both. CONSTITUTION:Partially tubular bodies A, B are primary injection-molded by respectively employing a fixed mold 100 and a movable mold 200 are female molds, and as leaving the primary-injected halved bodies A, B in respective female bodies, the movable mold 200 is opened in the direction of arrow E, and then slid in the direction of arrow F, and next, mold-matched in the direction of arrow G for being put into contact with each other. Besides, since partial grooves A1, B1 are preliminarily provided on the joint line of the partially tubular bodies (halved bodies) A, B, grooves 50, 50 are spirally formed on the joint line at the time when the joint line comes into contact with each other. And, onto both grooves 50, 50, molten resin is secondary-injected from an injection port (not shown), and therefore, the partially tubular bodies A, B are joined to each other in a fusing manner on the joint lines 40. Namely, inasmuch as mold-matched parts or joined parts do not appear on the end surfaces of attaching flange parts and the like, a synthetic resin tubular pipe with an excellent sealing property can be manufactured efficiently.

IPC: G01D5/245
Filed: 1987-02-06
Abstract: PURPOSE:To change measuring resolving power without altering hardware, by changing the measuring disolving power by shifting an input pulse train. CONSTITUTION:The signal read from the pixel of a CCD line sensor 4 blocked from light by an object 2 to be measured is introduced into an analogue circuit 6 and, subsequently, the pulse train corresponding to the pixel blocked from light is successively sent out form a binarization means 7. When a full-scale data is set by a mode setting means 9, a count pulse is sent out by a counting means 8 at each time when the clock pulse corresponding to said data is introduced. In accordance with this, binary data output is read in synchronous relation to a clock pulse by a D/A converter means 10 and, only during a period when said output shows a specific logical value, a signal of a definite level is smoothed to send out an analogue signal. By this method, the counting dissolving power of an input pulse is changed with the full-scale data.

IPC: H01L41/08
Filed: 1988-02-05
Abstract: PURPOSE:To scan a light beam repeatedly at a large maximum angle of deflection and at high speed by combining a reflecting mirror which has a mechanical natural vibration mode with a piezoelectric vibrator which has high frequency. CONSTITUTION:On a substrate 1 equipped with a 1st electrode 2, the piezoelectric vibrator 3 of high resonance frequency (hundreds of kHz) is installed, a 2nd electrode 4 is provided above the piezoelectric vibrator 3, and the center part of the reflecting mirror 5 whose top surface or reverse surface is made uneven is mounted on the 2nd electrode. Then when an AC electric signal is applied between the electrodes 4 and 2, thickness vibration corresponding to the frequency of the piezoelectric vibrator 3 is transmitted to the piezoelectric mirror 5 to generate a standing wave of vibration frequency coincident with the natural oscillation frequency of the reflecting mirror 5, thus obtaining the optical deflector which varies in the angle direction of the reflecting surface with time. Consequently, the deflection is possible at high repetitive scanning frequency and the large maximum angle of deflection is obtained.

Title: System for changing system definition
Inventor: NAKAMURA TAKAHIDE
IPC: G06F9/06
Filed: 1992-02-12
Abstract: PURPOSE:To automatically succeed definition information at the time of starting a system again by providing a system definition file and a construction change file and preparing a table for defining system construction by combining information in two files. CONSTITUTION:When a command is inputted from a terminal 11, a command process 13 is generated inside a system control part 6, and a processing is executed corresponding to the input command. When a command to disconnect another terminal 12 from the system construction is inputted, for example, the command process 13 is generated. This command process 13 erases the definition information concerning the terminal 12 from a system table 14 defining the system construction. Thus, when the processing is completed corresponding to the input command, the command process 13 writes the dynamic history of the construction change command in a construction change history file 8, updates the system table 14 in a main memory and informs the terminal 11 of a normal end message. Then, the terminal 12 is disconnected concerning the definition.

Abstract: PURPOSE:To make it possible to perform control highly accurately by connecting magnetoresistance effect elements in series in a parallel pattern at the interval of approximately (1/4).(2n+1)lambda(n=0, + or -1, + or -2,...) with respect to the period lambdaof repeating magnetic signals. CONSTITUTION:A sensor part is provided in a device 1. In the sensor part, the even number of magnetoresistance effect elements are connected in series in a parallel pattern at the approximate interval of (1/4).(2n+1)lambda(n=0, + or -1, + or -2,...) with respect to the period lambda of repeating magnetic signals which acts on the element 3a. The element 3a has the anisotropic effect of the magnetic resistance and has the same magnetism sensitivity direction. In this constitution, the output signal Vout of the device 1 is changed in an approximately sine wave pattern so that the value becomes the minimum and maximum values at every lambda/8. The output signal Vout becomes a signal having a frequency that is four times with respect to a magnetic field. As a result, even if a magnetic band 9 is provided at the outer surface of a turntable which is rotated relatively slowly, the highly accurate control can be performed.

CONSTITUTION:An alternate voltage of 3MHz is applied between elelctrodes 11 and 12 to form dot latent images on a recording material moving at a speed of 12 inch/sec. Since 16 electrodes 11 and provided and a dot latent image density of 300 dots/in. is conditioned, the time taken to write in one dot is 1/300X12X16=17.4mus, and the time taken for rising of discharge voltage is about 2 mus, and also for trailing of the voltage is about 8mus. The time interval during the period when effective voltage occurs is 7.3mus. Since the frequency of alternate voltage is 3MHz, the peaks of 3X7.4X2=44 times are produced. Negative ions, however, are all adsorbed on the surface of a dielectric material 14, and discharge times to be utilized for obtaining one dot latent image are 22 times. By utilizing discharge of 10 times or more, dot latent images free of dispersion of sizes can be obtained.

Abstract: PURPOSE:To enable a non-consumption part to be prevented from damage before its occurrence, by adjusting the operation of a clutch pedal to be felt heavy so as to enable an extent of wearing to be sensed by the driver if the wearing of a clutch disc advances to approach its limit of use. CONSTITUTION:When a clutch is released under the condition that the wearing of a clutch disc is less than a prescribed value, the actuating stroke SL=D<2>1/ D<2>2.SM of a release piston 24 in diameter of D2>D1 is smaller than the effective actuating stroke SM of a master cylinder piston 23 in diameter of D1, providing an input F1=D<2>1/D<2>2.FO of the piston 23 for an output FO of the piston 24.
