Title: Exfoliating method and device of electrodeposited metallic plate
Inventor: MATSUO HIROAKI
IPC: C25C7/08
Filed: 1979-10-30
Abstract: PURPOSE: To exfoliate the electrodeposited plate from the base metal without damage of the base metal, by moving blade edges along a circular locus, which are provided on a pair of scrapers, directing from the side face of the upper corner of one side of the electrodeposited plate toward the lower corner of the other side.  
     CONSTITUTION: Base metal 2 is fixed to a prescribed position of holder 3. Scrapers 5 and 5' are placed in position III, and the interval between their blade edges 10 and 10' is extended to a value larger than the thickness of base metal 2 by high parts 17 and 17' of cam 7. Here, when scrapers 5 and 5' are moved to position IV by the operation of cylinder 6, scrapers 5 and 5' move to low parts 18 and 18' of cam 7, and they are converged due to spring force, and blade edges 10 and 10' are caused to adhere closely to both faces of insulating material 15 of base metal 2 and slide toward electrodeposited plate 1 along these faces. Further, when scrapers 5 and 5' reach position V, blade edges 10 and 10' are inserted between electrodeposited plate 1 and base metal 2 to start exfoliation. Scrapers 5 and 5' move to positions VI and VII successively, and blade edges 10 and 10' move along the arc locus with pin 8 as the center, thus completing exfoliation.

Title: Method for verifying checksum in received data block and implementing method therefor
Inventor: BURUFUUKURISUTEIAN SHIYUTORETS
IPC: H04L12/70
Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To easily and quickly decide a data block start by logically connecting a bit with the initially transmitted bit of respective preceding data blocks and forming a new check sum. SOLUTION: At the start of search algorithm, the flip-flop of a shift register 4 is set to '0' in a control circuit 6 through output 10. When data are inputted, a check sum is formed and checked inside a comparator 5. Then, in the case that the check sum is not equal to a comparison value included in the remaining succeeding bit, the last memory location bit of the shift register 1 in the output activates the further different output 11 of the circuit 6. Then, the bit is logically connected to the bit transmitted to the respective preceding data blocks. Then, the influence of the bit D1 of the previous block on the contents of the flip-flop is additionally eliminated by the inversion of following clock pulses.

Title: On-off operation controller for motor-driven shutter
Inventor: MURASE KENJI
IPC: E06B9/68
Filed: 1988-06-08
Abstract: PURPOSE:To make sure of operation in avoiding any overcurrent from occurring by installing a drive delaying mechanism, while delaying each switch of multiseriate motor-driven shutters as long as a period of time when a large current flows at the time of starting, and starting them stepwise. CONSTITUTION:A drive delaying mechanism is installed in a control part 7 which controls each on-off operation of multiseriate motor-drive shutters 6 installed in a department store and a warehouse or the like in a concentrated manner. Then, on the basis of an ON command of a changeover switch, a driving command is outputted stepwise to respective switches 4 of these motor- drive shutters 6 as delaying them as long as a period of time when a large current flows at the time of starting at least these switches 4. With this constitution, these shutters can be opened or closed by simple switching and, what is more, any overcurrent due to simultaneous starting is thus avoidable.

Title: Controlling method of tracking
Inventor: TSUCHIYAMA YOSHIROU
IPC: G11B5/588
Filed: 1984-07-06
Abstract: PURPOSE:To realize a tracking controlling method which quickly restores a tracking disturbed condition caused when a magnetic head is chocked with foreign matters, by switching the output value of a delay means to a fixed value when omission of synchronizing signals is detected by a means which detects the presence of the synchronizing signals in information signals for a continuous period which is (n) times (n is an integer of 2 or more) longer than a fixed peried. CONSTITUTION:When foreign matters adhere to a magnetic head 2 and the reproduced output of the head 2 is extremely dropped, synchronizing signals cannot be extracted from a synchronizing separator circuit 15, since the output of a demodulator circuit 14 disappears. As a result, omission of signals is detected by an omission detecting circuit 16 and the input side of a switching circuit 17 is switched from a one-frame delaying circuit 8 to a DC generating circuit 18, and then, the loop of tracking control is disconnected. Therefore, the case where the output of the magnetic head 2 is extremely dropped and the state of obtained tracking error signals becomes worse and, as a result, a wrong tracking condition takes place, can be prevented. Moreover, the value of DC is transferred to the one-frame delaying circuit 8 from the DC generating circuit 18 at this moment. Therefore, the cause of the reproduced output drop is eliminated and a normal condition is restored.

The cooling water stuck on the inside wall surfaces of the body 2 in the form of small water drops evaporates to steam by the heat transmitting through the walls of the bodies 2 through the strip 1 and discharges to the outside through an outlet pipe 7 by depriving the walls of the heat of evaporation. The wall temp. of the bodies 2 is detected with a detecting end 9, and the opening of the valve 11 is controlled with a signal converter 10, whereby the wall temp. is maintained at a required temp. The wall temp. is easily controlled over a wide range.

Patent JP-H10333760-A (JP)
Title: Power circuit
Inventor: TSUKIMOTO SEISHI
IPC: G05F1/56
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To shorten the time up to stationary lighting while suppressing a rush current flowing through the lamp by providing a detection current setting part for gradually increasing a detection current in a current detection part, thereby detecting the current flowing through the load and performing control so that the rush current does not flow through the load by the detection current setting part. SOLUTION: When the output current Io of the power source increases and the output of a current detection resistance R3 becomes large with the output of the detection current setting part 32, a comparing amplifier U2 controls a transistor Q1 in its OFF direction and then the output voltage of the power source drops, so that the current of the load 2 decreases. When the power source is low in output voltage and decreases in its output current Io and the output of the current detection resistance R3 becomes lower than the voltage of the detection current setting part 32, the comparing amplifier U2 controls the transistor Q1 in its ON direction to raise the source output voltage and the current of the load 2 increases.  The current detection part 30 therefore performs current control in the rise period of the source output voltage Vo and when a stationary voltage is reached, the circuit becomes a constant voltage source which is controlled by an output voltage control part 20.

Filed: 1981-09-10
Abstract: PURPOSE:To obtain methacrylamide industrially, easily and safely, by removing the heat while neutralizing methacrylamide sulfate with ammonia accompanied by oxygen or an inert gas containing the oxygen in an aqueous medium under reduced pressure. CONSTITUTION:Methacrylamide sulfate is neutralized with ammonia in an aqueous medium to give methacrylamide. In the process, the pressure in a neutralizing tank 1 is kept at a given vacuum, usually 250mm.Hg or less, by a vacuum pump 7 connected with the bottom of a condenser 5, and ammonia is fed from a pipe 9, mixed with oxygen or an inert gas containing the oxygen, e.g. hydrogen or helium, from a pipe 11 in the course of the transfer and fed to the neutralizing tank 1. The oxygen or inert gas containing the oxygen accompanying the ammonia for the neutralization suppresses the occurrence of the polymerization of methacrylamide, and prevents the vibration and a roaring sound caused by the neutralization.
