Filed: 1982-05-28
Abstract: PURPOSE:To enable to normally or reversely rotate a rotor by providing a plurality of pole teeth which are directed toward the poles of the rotor and forming a stator by connecting a pair of magnetic legs at the teeth. CONSTITUTION:When coils 7a, 7b are not excited, a rotor 4 is stopped, the poles of a permanent magnet 2 are steadily stopped at the position opposed to the center of pole teeth 6f, 6g. The position of the rotor 4 of this state is detected, the coil 7a is energized so that the magnetic leg 6b side becomes N-pole side and the magnetic leg 6d side becomes S-pole side. Then, the poles of the permanent magnet 2 are respectively affected by repelling force between the legs 6b and 6d. Accordingly, the magnet 2 and hence the rotor 4 is rotated clockwise. When the coil 7b is, on the contrary, excited, the rotor 4 rotates counterclockwise by the same principle as mentioned above.

Filed: 1985-04-27
Abstract: NEW MATERIAL:Fluorine-substituted deuterated styrene derivative of formula I (D is deuterium; m is 1-5; n is integer of 0-4; m+n=5). EXAMPLE:Pentafluoro-pentadeuterated-alpha-methylstyrene (alpha-methylstyrene-F5,d5). USE:Monomer for photoconductive material.

Title: Measuring method for arc pressure
Inventor: YAMAMOTO HIDEYUKI
IPC: G01L7/00
Filed: 1978-07-25
Abstract: PURPOSE: To increase the performance by specifying the pressure detection media and pressure detector.  
     CONSTITUTION: The medium B in the fine tube 4 linking between the small hole 2h of the plate electrode 2 and the pressure detector 5 to detect the arc pressure is taken as liquid such as silicone oil or water, and the pressure detector 5 is specified as the semiconductor pressure conversion element having high resonant frequency such as piezoelectric element an piezo resistance element. Thus, the use of medium B as liquid such as water or silicone oil increases the resonant frequency in comparison with the use of gas such as air. And also, high resonant frequency can surely be detected at the pressure detector 5. Even if the arc pressure is measured by applying the AC current changing the polarity with a given period, current including ripple component, and periodically changing current, the effect of the resonance caused by timing change of applied current is restricted, and correct measurement can be made up to the higher frequency in the periodical change for the applied current.

Filed: 1979-07-18
Abstract: PURPOSE: To improve a contact detector in detection sensitivity of the contact condition between a tool and a workpiece by placing a winding for electromagnetic induction in the looped secondary circuit formed by the contact in order to raise induced voltage.  
     CONSTITUTION: In contact detection, when a main spindle 15 is rotated at a high speed, contacts 29 are closed. When the tool T and the workpiece W are relatively moved to contact with each other, the secondary circuit loop having the secondary winding 25 is formed.

Consequently, the induced voltage is increased, and if the contact resistance of a brush 21 increases, a large current can be supplied through the secondary circuit loop, so that the detection sensitivity of a detection circuit 28 for contact detection can be improved. Moreover, even if the contact resistance of the brush 21 varies a little, the contact detection can be reliably performed, so that safety can be improved.
