Title: Threading device for steel pipe
IPC: B23G1/22
Filed: 1992-03-30
Abstract: PURPOSE:To increase the strength of a screw joint as well as to enable a thread to be cut in such a way that the thread parallel portion of a thin wall steel pipe is left thick by using four tool blocks each of which holds a chaser having two ridge cutting edges. CONSTITUTION:A thread is cut at the end portion of a steel pipe while tool blocks 5 holding chasers 4a fitted on each die-head are being rotated. In this case, each chaser 4A is constituted to be of two ridge cutting edges, and four sets of tool blocks 5 are disposed symmetrically around the die-head. By this constitution, a thread can be cut in such a way that a parallel portion at the tip end of the thread section of a thin wall steel pipe is left thick, and thereby a screw joint can be increased in strength. As a result, pipe end swaging works and the like can be eliminated, consequently, a proposed method contributes much to cost reduction.

Title: Demodulation circuit for pal color signal
Inventor: OSAWA IKUO
IPC: H04N9/68
Filed: 1995-03-29
Abstract: PURPOSE: To correct distortion of a color signal accurately by adding an ALC addition pulse to a prescribed position of a demodulated color signal and supplying the resulting signal to a CCD. CONSTITUTION: A color video signal of the PAL system is applied to an input terminal 20. A frequency divider circuit 23 outputs an ALC addition pulse to its terminal 41 in response to a horizontal synchronizing signal. A detection circuit 32 closes a switch 34 in response to the ALC additional pulse to extract the ALC additional pulse added by an additional circuit 27. Then a voltage being a sum of a reference voltage Vref of a reference power supply 30 and a voltage of a reference power supply 36 of an additional circuit 27 is used for a reference voltage to detect a level reduction. Thus, a signal whose level is reduced is restored to the original level signal. As a result, a B-Y signal and an R-Y signal whose level is equal to the level before a CCD 7 are obtained at output terminals of ALC circuits 38, 39.

Title: Manufacture of reduced-reoxidized varistor
Inventor: MURAKAMI TOSHIAKI
IPC: H01C7/10
Filed: 1993-03-30
Abstract: PURPOSE:To reduce the voltage fluctuation of a varistor by heat-treating a sintered body in an oxidizing atmosphere after forming the sintered body by sticking a material composed mainly of aluminum to the surface of a molded body composed mainly of strontium titanate and baking the molded body in a reducing gas atmosphere. CONSTITUTION:A sintered body is formed by baking a molded body in a reducing gas atmosphere after molding the powder of a raw material composed mainly of strontium titanate in a desired shape and sticking a material composed mainly of aluminum to the surface of the molded body. Then the sintered body is heat-treated in an oxidizing atmosphere. Powder, paste, or a sheet composed mainly of aluminum is used as the material to be stuck to the surface of the molded body. Aluminum oxide can be used in place of the aluminum. Therefore, a varistor which is suppressed in voltage fluctuation and has a large nonlinear coefficient can be manufactured at a low cost, since the contrast between the high-resistance layer and semiconductor layer constituting the varistor becomes distinct.

Abstract: PROBLEM TO BE SOLVED: To form a display region which may be optically formable on a display sheet having multilayered uniform coating films by applying electric fields on observable conductive images so as to change an optical modulation layer from a first state to a second state. SOLUTION: An optically transparent conductive coating film 13 is formed on a substrate 12 and the optical modulation layer 30 is formed on this conductive coating film 13. A barrier 17 is applied on the optical modulation layer 30 and a photosensitive layer 14 is applied on this barrier layer 17. The photosensitive layer 14 is subjected to exposure and development, by which the observable conductive images 16 and nonconductive regions 18 are generated. The optical modulation layer 30 can take the two states. The observation of the observable conductive images 16 is made impossible in the first state and the observation of the observable conductive images 16 is made possible in the second state. AC voltage is applied to the transparent conductive coating film 13 and the electric fields are applied to the electrically grounded observable conductive images 16. The display is prevented from receiving the damage from the migration of ion within the layers and between the layers by using the AC voltage onto the optical modulation layer 30.
