Filed: 1983-07-01
Abstract: PURPOSE:To improve adhesion to a metal face by incorporating a specified heterocyclic compd. in a photopolymerizable compsn. polymerizable and hardenable with irradiation of actinic rays, for use in manufacture of printed circuits. CONSTITUTION:A photopolymerizable compsn. contains (A) a nongaseous ethylenically unsatd. compd. having plural terminal unsatd. groups, (B) a thermoplastic org. polymer binder, (C) a photopolymn. initiator activatable with actinic rays, and (D) a heterocyclic compd. represented by the formula in which R1-R6 are each H, alkyl, or the like; R5 and R6 may form pyrrolidine, piperidine, or the like ring together with N; and X, Y are each O, S, or the like. Said compd. (D) can improve adhesion to a metal surface without lowering photopolymn. sensitivity, and it does not cause harmful actions, such as reddening a copper surface and decoloring a dye, and does not bring about any disadvantageous trouble in manufacture, such as low solubility, and its addition can form an image high in sharpness.

Title: Oil pressure screw-down control method in temper mill
Inventor: HAMA KAZUO
IPC: B21B1/22
Filed: 1978-09-28
Abstract: PURPOSE:Not only to elevate precision of the elongation and quality of the product but also to make refining rolling speedy, by calculating the screw-down position variation amount from the comparison value of elongation of the strip, the roll abrasion compensation value, the speed compensation value, etc., and carrying out screw-down control. CONSTITUTION:The rotational frequency of the tension bridle rolls 2 and 4 at both the entry and the delivery is detected 13, 14 and is outputted, the elongation meter 15 inputs it, derives the elongation epsilon from the strip S, S' between both the rolls, and outputs it to the comparator 16. The comparator calculates the comparison value DELTAepsilon by comparing with the reference elongation epsilon0 of the setting unit 17, and outputs it to the potentiometer 18. Also, the first function generator 20 outputs the roll abrasion compensation value K1, based upon the number of rolling rolls P, and the second function generator 23 outputs the speed compensation value K2, based upon the line speed, etc. Based upon the aforementioned input value, the oil pressure screw-down control device 24 calculates the screw-down position variation amount of every moment DELTAS by the following expression, and controls the screw-down cylinder 10. DELTAS=G0.K1.K2DELTAepsilon (Hoerver, G0: control gain in case of a new roll and  steady roll speed.).

Title: Dram refresh control system
Inventor: AMANO TAKAHIRO
IPC: G11C11/34
Filed: 1988-05-17
Abstract: PURPOSE:To improve the processing speed of a whole system by supervising an address, with which data are written to a DRAM, and executing refresh control up to the maximum address or executing the refresh control only for a block, in which the data are written. CONSTITUTION:An address to be sent to an address bus, which is connected to the DRAM, and an address to be stored in a maximum address storing register 3-3 are compared by a comparator 3-4. When the address to be sent to the address bus is larger, this address is stored in the maximum address storing register 3-3. Addresses up to this maximum address, which is stored in the maximum address storing register 3-3, is cyclically refreshed. Thus, a time to be needed for the refresh can be dynamically controlled to be necessarily minimum and the processing speed of the whole system can be improved.

Title: Printing method
Inventor: MATSUYAMA KENTARO
IPC: G03F1/00
Filed: 1988-05-17
Abstract: PURPOSE:To enable light printing which is economical and finely precise by using the printed original obtd. by thermal transfer of the printing output from an information output terminal on original paper via a thermal head and ink ribbon directly as the block copy of an offset printing machine. CONSTITUTION:The original paper 1 formed by printing on the original paper 1 subjected to a surface treatment so as to maintain hydrophilic and water retaining properties via the thermal head 3 for information signal output attached to the information output terminal and the ink ribbon 2 having high lipophilic and water repellent properties is used as the block copy. The fine particles of the lipophilic ink dispersed in water are, therefore, adsorbed selectively on the lipophilic printing part and the non-printing part is covered with the water and is prevented from being stuck with the particles of the hydrophilic ink. The ink patterns 4 of the block copy applied selectively with the ink in the printing part in such a manner are once transferred to a transfer cylinder 6 and are finally transferred to paper 7 by the principle of an ordinary offset printing machine. The simple and highly precise printing is thereby enabled.

Title: Output buffer circuit
Inventor: WAKAMATSU MASATAKA
IPC: H03K19/0175
Filed: 1989-05-13
Abstract: PURPOSE:To reduce power consumption and a noise by controlling the gate of a transistor arranged between an output part and prescribed potential by detecting an output level, and increasing/decreasing the driving capacity of the transistor corresponding to a detected level. CONSTITUTION:The level Vth of the logical threshold value of an inverter 4 is set at 3/4Vcc. Therefore, the output signal VDET of the inverter 4 goes to a high level within the range of the output level of the output part 5 between ground potential and 3/4Vcc, and goes to a low level within the range between 3/4Vcc and Vcc. Thereby, an out enable signal OE and a data signal Data go to the high levels and the output of a NAND circuit 10 goes to the low level only when the output level of the output part 5 is set between 3/4Vcc and Vcc, thereby, the driving capacity of a P-channel MOS transistor 3 can be increased. Therefore, the level transition of an output signal D is performed with the transistor 3, and fast access time can be secured, and also, the power consumption can be suppressed, and the noise can be reduced.

Thereafter, the difference is compared with the value of a reference time 100, when the difference is larger, that the difference is in the reference value is notified. When the difference is smaller than the value of the reference time 100, that it is over the value of the reference time is notified.

IPC: C02F1/48
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To improve the capacity of human waste treatment and to reduce cost by sterilizing highly concentrated sludge flocculated to form floc by applying low voltage DC current to human waste septic tank sludge and simultaneously forming and recovering. SOLUTION: A small-sized lightweight human waste sludge concentrating device 11 is provided in a line for pulling out excess sludge. A titanium electrode as an anode and a stainless electrode as a cathode are provided in the human waste sludge concentrating device 11 and week DC current is applied between the electrodes. The human waste sludge is agglomerated to cause flocculation action by applying current to break the negatively charged hydration of the human waste sludge. A turbidity component is removed by the bond by van der Waals force with the flocculation action. The sludge has about pH 6.5-7 and then, the ζ-potential of the turbidity particle is neutralized to lower the turbidity and to increase a supernatant to be highly concentrated. The recovered sludge is easily reutilized because the sterilization effect occurs at the same time.
