Title: Mask alignment
Inventor: SUZUKI SHIGEO
IPC: H01L21/30
Filed: 1986-06-12
Abstract: PURPOSE:To enable an azimuth of a single-crystal mask substrate to be exactly and easily detected, by using a Bragg's reflection phenomenon of X-rays on the mask substrate. CONSTITUTION:X-rays of only desirable wavelengths from a X-ray generating device 1 are made to pass through a monochrome meter 2. The Xrays of desirable wavelength obtained from the meter 2 are reflected on a single-crystal mask substrate 3. A detector d detects the X-rays reflected on the substrate 3. Because a reflection factor of X-rays on the single crystal is extremely sensitive to the angular change of the substrate, even a small crystal shift of 0.1 second or so can be detected. Hence, the azimuth of the substrate 3 can be exactly and easily detected.

Title: Motor brake power supply

IPC: H02P3/04
Filed: 1977-11-16
Abstract: PURPOSE: To econimically control coil current by inserting a capacitor while brake coil current is being held.  
     CONSTITUTION: When brake coil current I c  is applied and the brake is sucked, then a motor M starts, motor current I m  decreases. Accordingly, the inter-terminal voltage of a resistor R 1  is lower than the Zener voltage of a constant diode ZD 1  and a thyristor Thy2 does not operate. Since only the thyristor Thy1 is igited, a capacitor c is inserted in a brake coil BC in series. When the copactor C is inserted like this, brake coil current decreases until a fixed level and the loss generated in the brake coil BC is reduced.

Abstract: PURPOSE:To permit an unmanned covering stage by providing optical fibers to the front and rear of the flat plate part of a thin-walled ribbon wire and plastically working the ribbon wire to an S shape by means of rolls, dies, etc. to enclose the two optical fibers into the respective curved parts of the S-shaped part.

This method is executed by using the rolls, dies, etc. so that the optical fibers are covered in the form of enclosing the same to the inside of the parts curved to the S shape. The optical fibers can be made to exist at the two points in the curved parts 21, 22 for contg. the optical fibers by the spaces to accommodate >=1 pieces of the fibers. Since the S-curved parts have elastic force against the pressure from above and below, the optical fibers can be conveniently enclosed therein and it is also possible to vary the size of the two parts curved to the S shape. The substantially unmanned preparation is thus permitted and the production cost is reduced.

Title: Dry-type developing device
Inventor: NOGUCHI MATSUSABURO
IPC: G03G15/09
Filed: 1985-06-26
Abstract: PURPOSE:To make a printing density uniform by detecting the printing density of printing data by means of a printing density counting circuit and increasing and decreasing the supplying quantity of a developer in accordance with the printing density detecting the supplying quantity of the developer which adsorbs magnetically on the periphery of a developing roll and contributes to development. CONSTITUTION:According to the signal of the printing density counting circuit 10, a rotational frequency control circuit 11 controls the rotational frequency of a motor 8b. When the printing density is high, the rotating speed of the motor 8b, that is, the rotating speed of a permanent magnet 2b, is increased, and the supply of the developer 6 is increased so that the crest height of the developer can be made longer. On the other hand, when the printing density is low, the rotational frequency of the permanent magnet 2b is slowed down to decrease the supplying quantity of the developer 6. Thus a developing part keeps balance between the consumption and the supply of the developer 2b changing in accordance with an electrostatic latent image density, whereby an excellent image with a uniform printing density can be obtained.
