Title: Electric wire connecting method and structure
Inventor: MATSUMOTO SHINICHI
IPC: H02G15/08
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To simply form a splicing part for connection of electric wires. SOLUTION: A flexible protection material 11 made of resin or rubber is formed with a U-section some greater than an intermediate joint terminal 10 having U-section with the two-side barrels continued at the bottom surface and with a length greater than that of the intermediate joint terminal 10. One side of each barrel of the joint terminal 10 is protruded farther than one side of the protection material 11 while the other side of the protection material 11 is protruded farther than the forefront of the other side of the barrel, and in this condition, the joint terminal 10 is secured to the inner surface of the middle part of the protection material 11 about its longitudinal direction, and then the part of the cores overlapped is inserted to the joint terminal 10 laid on the inner surface of the protection material 11.  The two barrels are caulked together with the protection material 11 into pressure attachment, and thus the intended intermediate splicing part is accomplished in such an arrangement that the periphery of the terminal 10 in pressure attachment to the cores is covered with the protection material 11 simultaneously.

Title: Method for joining pipes
Inventor: HIRAI KENJI
IPC: B23K9/028
Filed: 1992-08-10
Abstract: PURPOSE:To provide the method for joining the circumferential joint of pipes reformed in such a manner that a level difference does not exist on the inner side of the joining part of the pipes while the advantages of the method for amorphous diffusion joining are effectively utilized. CONSTITUTION:This method for joining the pipes consists in joining the circumferential joint of the pipes by inserting an amorphous brazing filler metal between the end faces on the joining side of the pipes 10, 12 to be joined, heating the inserted amorphous brazing filler metal and joining the pipes in the vicinity thereof and melting and solidifying of the amorphous brazing filler metal. The inner side part of the joint part 14 from the joining side end of the one joined pipe to the joining side end of the other pipe is subjected to a welding treatment or melting treatment by inert gas arc welding after joining of the pipes 10, 12, by which the inner side part is so smoothed as to avoid the presence of the level difference therein.

Title: Liquid crystal display device
Inventor: TAKAHATA MASARU
IPC: H01L29/786
Filed: 1990-09-03
Abstract: PURPOSE:To obtain the display device which exactly displays a halftone and has excellent display quality by outputting the selection signal to be impressed to a transmission gate TFT as the potential decreasing with time. CONSTITUTION:A display signal Vsig is impressed to one source/drain of the transmission gate TFT Q1 and the selection signal phi is impressed to the gate of the Q1. The selection signal phi is an on-voltage at a certain point of the time when VG is an on-voltage and thereafter, this signal drops gradually until finally the signal turns to be an off-voltage. The transmission gate TFT Q1 controlling the supply of the display signal Vsig to the signal electrode 1 attains an on-state and thereafter, the potential of phi falls gradually if the gradually dropping selection signal phi is impressed at specified timing and, therefore, the number of the carriers induced at the SiO2/i layer boundary is gradually decreased. Namely, the number of the carriers moving to the liquid crystal part decreases extremely at the time the transmission gate TFT Q1 attains the off-state. Then, the potential of the liquid crystal part does not fluctuate so much and, therefore, the degradation in the display quality of the halftone is obviated.

IPC: H04N9/64
Filed: 1993-09-20
Abstract: PURPOSE:To provide a line cyclic color signal noise reducing device which can reduce the color drops end can secure a high effect of the electric field of any input signal. CONSTITUTION:An input video carrier color signal is added to a delayed carrier color signal by a 1st addition circuit 1 and supplied to an inter-line difference detecting circuit 5. Thus, a line correlation signal l is detected. Meanwhile a vertical change component is calculated by an Hadamard transformer circuit 8 and supplied to 8 2nd gain control circuit 9 for control of the amplitude. Then the limitation of amplitude is applied to the result of the circuit 9 through a limiter circuit 10. This limited signal is added to the signal l by a 2nd addition circuit 11, and the result of this addition is supplied to a cyclic value control circuit 6 where the cyclic value is decided. Thus, the circuit 2 is controlled. Furthermore, the signal controlled by the circuit 2 is subtracted from the input video carrier color signal by a 2nd subtraction circuit 3 together with reduction of noises. Thus an output video carrier color signal (m) is transmitted. Then the signal (m) is supplied to a 1st line delay circuit 4 and serves as the delayed video carrier color signal for the next scanning line.

Abstract: PURPOSE:To shorten time spent until a next object to be checked can be checked by providing an attachment vaporization heater for heating the tip of a heating needle after the heating needle leaves the object, in a device for testing a thermal cracking gas generated when the thermal needle comes in contact with a plastic waste. CONSTITUTION:A thermal needle 2 is provided in a main probe system 1 and a contact adjustment ring 3 slides out and in freely inside a tip part through a compression spring 4. In addition, a likewise cylindrical attachment vaporization heater 5 is provided on the inner surface of the ring 3 or in the main probe system 1 so that the inner temperature is maintained at a constant level so as to enable the plastic to be vaporized instantaneously. The ring 3, after coming in contact with an object to be checked, recedes into the main probe system 1 with the heater 5, causing the thermal needle 2 to come in contact with the object. Further, after detection operation, both ring 3 and heater 5 are pushed out of the main probe system 1, and the thermal needle 2 enters into the heater 5, being separated from the object, thus resulting in the complete vaporization of an attachment. The thermal cracking gas generated by the object is sent to a HCl detector.

Title: Predicted stall prevention system for motor drive inverter
Inventor: TAKIZAWA YOSHITOMO
IPC: H02P27/06
Filed: 1986-10-01
Abstract: PURPOSE:To suppress the increase of load current and to prevent an inverter system from malfunctioning, by differentiating the load current and detecting the current increase rate. CONSTITUTION:A differentiator 8 differentiates load current I and detects its current increase rate. The third comparator 9 outputs a constant speed command or decceleration command if the current increase rate exceeds the reference increase rate S as arranged. On that account, even through the load current I increases abruptly due to the sudden acceleration of a motor 3 or the sudden increase of the load connected to the motor 3, the differentiator 8 detects it promptly and controls the motor 3 in constant speed or in decceleration. No load current I will thereby rise up to the cutoff level I2.

Abstract: PURPOSE:To prevent the cracking, subsidence, and joint deviation of floor material by a method in which rigid floor panels such as stone plates are attached through cement mortar or resin adhesive to the surface of a base and a mortar of good fluidity is injected into the joints. CONSTITUTION:A rigid floor material 3 such as stone is attached through cement mortar or resin adhesive 2 to the surface 1 of a base and cured for a given time period. In this case, the adhesive 2 is used to an extent that it does not leak from the surface or sides of the floor material 3. A mortar 5 having good fluidity is then injected into the joints to uniformly pack it into the back side of the material 3, and a joint material 6 is packed into the joints, followed by surface finishing of the floor material 3. The floor free of cracking, subsidence, and joint deviation even when used for long periods can thus be constructed with high efficiency.
