Title: Porous membrane and its production
Inventor: NAMITA YASUO
IPC: B01D71/78
Filed: 1988-10-26
Abstract: PURPOSE:To obtain a porous membrane suitable as an excellent ion exchange membrane by a simple process by grafting an acidic monomer onto the porous surface of a porous membrane comprising a basic polymer. CONSTITUTION:The porous surface of a porous membrane comprising a basic polymer is treated with a photosensitizer, and an acidic monomer is photografted onto the surface. As the basic polymer, a polymer containing a -CONH-, -NH2 or -NH-group or a material on the porous surface of which this polymer is present is used. Examples of the porous membrane include ones prepared from polyamides such as nylon 6 or nylon 66 and one prepared by impregnating or coating a porous material such as a cellulose membrane with polyethyleneimide and subjecting the film to crosslinking with, e.g., an acid. Examples of the acidic monomer include vinyl monomers containing acid groups such as a sulfonic or carboxyl group [e.g., vinyl sulfate or (meth)acrylic acid]. Any photosensitizer can be used as said photosensitizer, as far as it is one used for a photoreaction.

Filed: 1990-10-08
Abstract: PURPOSE:To surely detect the finish of the data reading of a paper tape at a low cost by controlling an operation by a signal from a light receiving part, and providing a signal waveform comparing part comparing a read waveform of a data hole in the light receiving part and the read waveform at the finish of a paper tape travelling. CONSTITUTION:A signal waveform comparing part 7 is started by the signal from a light receiving part 5, and a read waveform (a) read out in the light receiving part 5 is inputted in the signal waveform comparing part 7 only by the number of unit code. Next, when the read out of a paper tape 6 is proceeded and a read waveform (b) of each unit code is an all hole, this is the waveform of no paper tape, the signal waveform comparing part 7 outputs a commutation point (c) from the read waveform (a) to (b) in a tape reading finish detecting part 8, and the travelling of the paper tape is stopped by a driving control part 1. Thus, a special exclusive sensor is unnecessiated, and it is possible to detect the finish surely, simply and at a low cost.

Title: Simulator for training
Inventor: TSUJI TOSHIHIKO
IPC: G09B9/00
Filed: 1988-10-25
Abstract: PURPOSE:To equivalently simulate a step-out phenomenon when an accident occurs in real time by accurately calculating stability calculation and previously storing a system stage in a constant cycle in a preparation step and reading out and using the stored data when training is to be executed. CONSTITUTION:In the preparation step, the stability calculation is executed in a CPU 1-c, and the operation of a step-out relay and the existence of the trip of a breaker are stored in an external memory 5-c after a relative time of day is added to them. Next, in a training execution step, the system state before the accident occurs is read out from the external memory 5-c through a CPU-b and displayed on a system monitoring board 6. Next, when a button for executing the training is depressed, the system state stored in the external memory 5-c is read out and displayed on the system monitoring board 6, and an applicable breaker out of the data base of a shared memory 7 is made into a trip state. Further, the CPU 1-c periodically executes calculation for calculating a tidal current and a frequency after the point where the CPU 1-c executes the stability calculation. Thus, the step-out phenomenon when the accident occurs can be equivalently simulated in real time.

Title: Debugging device
Inventor: OGUMA YASUYUKI
IPC: G06F11/28
Filed: 1987-10-23
Abstract: PURPOSE:To improve the program debugging speed by adding a break processing means, a break condition setting means and a resetting means into a substitute storage after removing a ROM of a system to be tested and connecting the substitute storage instead. CONSTITUTION:A break condition setting means 12 interprets the control information written into a 2nd substitute storage 2 via a control information writing circuit 3 and writes the trigger information into a microprocessor 31. A resetting means 13 gives a specific instruction to the microprocessor 31 and resets a break state to an executing state of a program to be debugged. A break processing means 11 works when the microprocessor 31 is shifted to a break state based on the trigger information and interprets the control information written into the storage 2 to start both means 12 and 13. Thus the program debugging speed is increased.

Abstract: PURPOSE:To drive a working machine on the high load side with a demand speed by increasing the absorption torque of an oil-hydraulic pump on the high load side so that the resultant absorption horse-power of oil-hydraulic pumps in case one of the pumps is loaded high and the other loaded low. CONSTITUTION:On the basis of outputs from oil-hydraulic sensors 13, 14, it is judged whether the differential pressure between oil-hydraulic pumps 1, 2 is over a certain set level P0 - if one of the pumps is loaded high while the other loaded low, another judgement is made whether the resultant absorption horse-power calculated on the basis of the outputs from the sensors 13, 14, outputs from swash plate angle sensors 15. 16, and output from a revolving speed sensor is smaller than the max. horse-power of the engine 3. If judgement is such that the resultant absorption horse-power is smaller than the max. horse- power of the engine. it shall be further judged whether the discharge pressure of the oil-hydraulic pump 1 is smaller than that of the other pump 2 - if the pump 2 is with high load, a process is executed to emit a characteristic setting signal S so that the absorption torque T of the pump 2 enlarges. Setting of the iso-torque characteristic curve is made so that the resultant absorption horse-power attains the max. horse-power of the engine 3.

Title: Lock method for carriage in magnetic disk device
Inventor: TSUKADA MITSUYOSHI
IPC: G11B21/12
Filed: 1990-10-09
Abstract: PURPOSE:To lock a magnetic head to a same position stably at all times by utilizing a counter electromotive force induced by a magnetic disk drive spindle motor whose number of revolutions is coasted simultaneously or just after power of a magnetic disk device is interrupted so as to move a carriage assembly and a lock lever to a desired position. CONSTITUTION:A counter electromotive force induced at least in one of exciting windings A, B, C of a spindle motor whose number of revolutions is coasted simultaneously or just after power of a magnetic disk device is interrupted activates a retract circuit 111 to move a carriage assembly 50 and a lock lever 90 to a desired position, to couple and lock the both. Thus, even when the magnetic disk device is in operation, it is not required to supply a current to the lock mechanism to make the power consumption of the device low and unlocking is almost not caused even to an external shock and vibration.
