Title: Transmission electron microscope
Inventor: TAKAHASHI YOSHIO
IPC: H01J37/20
Filed: 1995-03-24
Abstract: PURPOSE: To provide a transmission electron microscope with which electron beam irradiating position and deflection of electron beam after transmission are not affected even an outside magnetic field is applied to a specimen. CONSTITUTION: Three magnetic field generating means 1a, 1b, 1c are arranged along electron beam track 7, a magnetic field is applied to a specimen 4 by the magnetic field generating means in the center, and magnetic fields in inverse direction to that of a magnetic field applied to the specimen are generated by magnetic field generating means in both sides.

Title: Endless tracked belt
Inventor: SAKAI KENICHI
IPC: B62D55/253
Filed: 1980-05-15
Abstract: PURPOSE: To accurately prevent wheels from slipping off in a rubber endless tracked belt for a crawler running device and make the weight of the endless tracked belt lighter by providing the engagement holes of driving wheels in the concave at the center of the endless tracked belt main body with a concave cross-section and making the bottom of a core bar equal to the grounding surface of the endless tracked belt.  
     CONSTITUTION: Since the bottom wall 10 of the concave 8' in the embedded core bar 8 is positioned lower than the cord layer 6 toward the contact side, the central drum is naturally positioned in the grounding side deeper than the cord layer 6. Consequently, when the endless belt 1 is applied between the driving and induction wheels, the cord layer 6 as the curvature center in the buckling surface of the endless belt 1 is positioned at the center of both wheels mentioned above more than the external surface of the center drum 13. Thus, this endless belt 1 has the small axial length between both wheels mentioned above or prevents the wheels from being removed solong as the cord layer 6 is broken. Besides, since the bottom wall 10 of the core bar 8 is almost on the same level as the contact surface 1' of the endless tracked belt main body 1, the core bar 8 and the bottom wall 10 does not generate a fault and the friction and damage can be prevented.

The circuit 20 calculates the coefft. of compensation of the spectral fluctuation in accordance with both measured values and the constant including the wavelength of the light sources and outputs the measured value subjected to the compensation of the spectral fluctuation. The measured value is thus substantially unaffected by the wavelength fluctuation and the high accuracy is obtd.

Title: High-speed feed controller of tape
Inventor: FURUTA TAKAAKI
IPC: B65H23/18
Filed: 1983-04-14
Abstract: PURPOSE:To set the tape speed at a fixed level in a fast forward mode by detecting the revolving cycles of both the take-up and supply reels of a magnetic tape and then controlling the drive torque of a motor which drives the take-up reel based on the detected revolving cycle. CONSTITUTION:The right and left reel revolving cycles are referred to as Tt and Ts respectively, and the values of Tt, Ts and Tt<2>+Ts<2> are shown in a graph. As a result, the value of Tt<2>+Ts<2> is constant at any position of a tape as long as the tape speed is constant. On the contrary, the tape speed can be controlled to an optional fixed level when the value of Tt<2>+Ts<2> is set at an optional fixed level. Here the tape speed is controlled so that the value of Tt<2> is equal to 1/900 compared with that of a reproduction mode. Then the tape speed can be controlled at a fixed level equal to 30 times as high as that of a reproduction mode when the tape is fast forwarded. Then it is discriminated whether the tape speed is higher or lower than the level equal to 30 times as high as that of the reproduction mode. When the tape speed is lower than said level, the revolving cycle of a reel drive disk is increased. Therefore the value of Tt<2>+ Ts<2> is larger than the comparison data C. Thus the driving torque of a reel motor is increased to increase the tape speed.
