Title: Improvement of yield and water filterability in paper-making process and in waste water-treating process, and sulfonated phenol-formaldehyde resin used in the method for making paper
Inventor: TAKATSU HISAO
IPC: D21H17/48
Filed: 1996-01-09
Abstract: PROBLEM TO BE SOLVED: To provide a method for improving a yield and water filterability, capable of not coloring the paper, prolonging the life of the product, and exhibiting a stable yield-improving effect also for fillers and paper materials containing deinked pulp in large amounts, and to provide the yield improvement- accelerating agent used in the method. SOLUTION: This method for improving the yield and water filterability in a paper-making process or in a waste water-treating process. Therein, both a special phenolic resin and polyethylene oxide(PEO) are used. The phenolic resin is a sulfonated phenol-formaldehyde resin synthesized by sulfonating a phenol compound and subsequently condensing the sulfonated phenol compound with formaldehyde. The phenol compound to be sue-fonated is preferably bisphenol A and bisphenol S. This method improves the yields of fine fibers and fillers, and enables to save the paper raw materials and lower a load for treating waste water.

Title: Video signal input circuit
Inventor: OGINOYA NAOKI
IPC: H04N5/04
Filed: 1994-02-18
Abstract: PURPOSE:To perform sure detection of synchronizing signals from the video signals of positive electrode synchronization and dispersal elimination by the use of the same circuit. CONSTITUTION:Before a synchronizing processing circuit 16 is locked, cyclically changing waveforms are superimposed on input signals by an integration circuit 17, an amplifier 18 and an adder 13. Thus, even when the center level of the input signals is not at a desirable position, since a period passing through the center level of an A/D converter 15 is surely generated, the detection of a synchronous part is facilitated. Also, after the synchronizing processing circuit 16 is locked, since the waveforms opposite to dispersal are prepared by the integration circuit 17 and the amplifier 18 and superimposed by the adder 13, dispersal components are eliminated.

Title: Video type dubbing device
Inventor: TOMITA MASAO
IPC: G11B5/027
Filed: 1982-02-12
Abstract: PURPOSE:To reduce the time for dubbing, by increasing the reproducing speed of a master tape, the number of rotary heads provided to a rotary cylinder and providing a suitable taper to the shaft of the rotary cylinder. CONSTITUTION:On the rotary cylinder, for example, 6 sets of rotary heads PR1-PL3 having different azimuth angles are placed on a straight line, as three pairs at an interval of 60 deg., so as to obtain alternate azimuth angles L, R along the circumference. Since the tape speed is three times that at the recording and the rotary head is driven in the same speed, the rotary head, e.g., PL1 scans over the three tracks of L1, R1, L2. Since no signal is reproduced in scanning the track R1, it is required to correct the slope of scanning locus. Then, the titled angle of the cylinder is shifted so as to be shifted on the two tracks at the end of scanning without shifting the head at the start point of scanning of the PL1.
