Title: Signal converting circuit
Inventor: IMAZEKI RIYOUJI
IPC: G05B19/416
Filed: 1979-08-25
Abstract: PURPOSE: To ensure a smooth working of the machine mobile part, by converting the signal showing a large extent of shift of the variation component into the signal having a small variation component and then applying this signal to the servo system.  
     CONSTITUTION: The signal (a) showing the extent of shift is supplied according to the clock (b). And in case n=4 is satisfied only for the memory element M 1  at the time t 1 , 4 is written. In this case, other memory elements M 2 WM 4  are 0, and accordingly the output of the adder circuit ADD becomes 4. And then this output is turned into 1/4 to change the output to 1. Both the contents of the element M 1  as well as the input 4 are shifted to the M 2  at the time t 2 , and as a result the addition output becomes 8 with the output of the circuit DV turned to 2. In the same way, the outputs 3 and 4 are obtained at the times t 3  and t 4 . Accordingly, the input signal which varies from 0 to 4 can be converted into the output signal having the changing extent of 1/4. And the output varying by 0.5 is obtained at the times t 18 W t 21 . In such way, the input signal (a) is converted to obtain the output signal (c) having a small extent of change. As a result, a smooth shift can be secured for the machine mobile part.

Title: Production of chlorine of little oxygen content
Inventor: SUGAWA HIROSHI
IPC: C25B1/46
Filed: 1981-07-14
Abstract: PURPOSE:To obtain chlorine of little oxygen content without application of any special refining treatment in the stage of producing chlorine by electrolysis of salt water by contg. little amt. of aliphatic alcohol in the salt water. CONSTITUTION:In the stage of producing chlorine by electrolysis of salt water with diaphragm, ion exchange membrane or other methods, aliphatic alcohol such as ethylene glycol is contained at 10-10,000ppm in the slat water. The aliphatic alcohol is oxidized by oxygen or the precursor of oxygen in the electrolytic cell and the greater part thereof turns to carbon dioxide and water. By the above-mentioned method, the oxygen in the chlorine is easily decreased and the electric current density of the electrolysis is increased. Further the contents of chlorates in the electrolyte is reduced.

Title: Resin combination type magnet
Inventor: TAKEI MITSURU
IPC: H01F1/053
Filed: 1991-05-14
Abstract: PURPOSE:To obtain a ring-like thin resin combination type magnet of less than 1mm in thickness. CONSTITUTION:A bisphenol solid epoxy resin having a softening point of lower than 100 deg.C is dissolved by organic solvents such as xylene, methyl ethyl ketone, etc., together with a hardening agent. The obtained solvent is mixed with a magnetic powder and agitated in a vacuum drying machine to remove the organic solvent through volatization, thereby a solid epoxy resin is precipitated on the surface of the magnetic powder. The powder has an excellent fluidity without any viscosity because the resin is solid, so that it becomes possible to fill the powder into a molding for forming a ring-like thin magnet of less than 1mm in thickness. As the result, the ring-like thin magnet that has never been produced by the conventional methods can be obtained easily.

Title: Driving device for solenoid valve in combustion equipment
Inventor: KANEKO MITSURU
IPC: F23N5/00
Filed: 1980-08-09
Abstract: PURPOSE: To economize the power to hold open a solenoid valve by a method wherein the pulse width of the driving signal of the switching element in an oscillating transformer is changed with the output of a flame sensor generated by ignition and burning in the combustion equipment such as a hot water supplier or the like.  
     CONSTITUTION: When a burner is started to burn, a flame current flows in the flame rod 5 of a flame sensor (a) to the direction indicated with the arrow due to the burner flame. A field-effect transistor 17 turns OFF by the voltage drop caused by the flame current under the existance of a resistor 4, resulting in bottoming-up the minus input terminal voltage of the comparator 18 in a variable pulse width circuit (c). At this time, the driving wave form to switch the transistor 27 in a DC-DC convertor (e) is the one composed of the output of the comparator 23 in a driving circuit (d) and the output of said comparator 18. This composition makes the width of the driving pulse narrower and the ON time of the transistor 27 shorter, resulting supplying, to the valve 30, the small electric power only necessary to hold open the solenoid valve 30.

IPC: F16H61/12
Filed: 1994-05-24
Abstract: PURPOSE:To prevent the generation of an excessive shift shock during failure in operation of a solenoid valve for controlling a clutch. CONSTITUTION:A proper oil pressure responding to an operation state is directly fed to the clutch chamber 4a of a clutch 4 for a lever shift by a normally- opening type solenoid valve 3 for controlling a clutch not through an accumulator at shift. The trouble of the solenoid 3 for controlling a clutch is detected by an electronic control unit(ECU) 5 and when the trouble of the solenoid valve 3 is detected, energization to the solenoid valve 3 is disconnected and the solenoid 3 is normally opened. A duty command value to the solenoid valve 6 for controlling a line pressure is controlled by an ECU 5 during a gear shift so that a line pressure of oil fed to the clutch 4 for a gear shift through the solenoid 3 for controlling a clutch is decreased.

While the thickness distribution of Si is preferably symmetrical with a vertical plane in terms of a steel sheet shape, the effect may be obtd. even if the distribution is asymmetrical.  The silicon steel sheet adequate for iron cores of transformers, reactors, motors, etc., is obtd.
