Title: Capstanless tape driving method and information recording and reproducing device
Inventor: YANAGIHARA NORIHISA
IPC: G11B15/467
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To reduce a speed variation when recording and reproducing and to enable good recording and reproducing in a tape driving system where a capstan is omitted and a tape is directly transferred between two reels of a supply reel and a take-up reel. SOLUTION: A load torque compensator and a phase control compensator 26 are added to a tape speed control system on the take-up side, and a gain of a speed control compensator 21 is adjusted in accordance with a speed detecting period. Thus, in the recording and reproducing time, speed fluctuation generated due to fluctuation in load torque of a variation of tension, etc., is reduced to be less than an allowable value, and hence good recording and reproducing can be performed.

Title: Driving method for synchronous motor
Inventor: KUME TSUNEO
IPC: H02P27/06
Filed: 1991-06-26
Abstract: PURPOSE:To obtain a highly efficient synchronous motor for driving vehicle having excellent operating characteristics by externally switching the windings between star-connection and delta--connection while shifting so that the current to be applied on the motor has synchronous phase when the rotor reaches a preset rotational speed. CONSTITUTION:Connection of unit windings 10 for respective phases of a synchronous motor 1 is switched through contactors A, B based on a switching command. A rotational angle detector 4 mounted at the end of rotor shaft of the synchronous motor detects a signal Sd which is converted through a polarity detector 24 into a pole position signal Sp of rotor. A phase shifter 25 then regulates the pole position signal Sp to be synchronous with the current being applied on each phase winding 10 of the synchronous motor according to star/delta connection and the rotational angle of rotor to produce an output signal Sf. When switching is made from star connection to delta connection, switching commands are delivered from a switching timing commander 5 to a winding switcher 3 and an inverter 2 at the time when a detected value Vs of actual speed matches with a preset speed level Vo.

Abstract: PURPOSE:To easily detect variation in illuminance due to surface unevenness or strain in a sample, and to decide on whether the sample is normal or not by detecting the reflected light of parallel luminous flux illuminating the sample and finding an illuminance distribution on the sample, and comparig it with a reference value. CONSTITUTION:A sample 1 on a sample base 10 is irradiated with parallel luminous flux from a light source 2 through a lens 9, and its reflected light is detected through a lens 11 and a photoelectric conversion part 12. If the sample 1 has uneven parts 13-15, those uneven parts serve as a concave mirror and convex mirror to scatter the illumination light. Then, a signal having an illuminance distribution corresponding to the uneven parts 13-15 is detected. The mean value of the entire luminous flux is calculated and multiplied by a constant to find an upper-side and a lower-side reference illuminance value, thereby decidig on whether the sample is normal or not from the number of light and dark parts and area corresponging to said illuminance. Further, a reference sample having a completely specular surface is arranged near the sample 1 to use the reflected light as the mean value.
