Title: Rotational frequency control system for dc motor
Inventor: FUKUSHIMA KIYOSHI
IPC: H02P7/06
Filed: 1989-04-18
Abstract: PURPOSE:To control correctly by a method wherein both of the leading edge pulse and the trailing edge pulse of encoder pulse are read into a CPU upon the low-speed mode of a DC motor. CONSTITUTION:In the control of the rotational frequency of a DC motor 15, the pulse of the encoder 20 is converted into an electric signal by a photo- interrupter 21 and is inputted into the INT terminal of a CPU 23 through the frequency multiplier 22 of the pulse. Then, a rotational frequency control signal, controlled through PWM, is outputted from the OUT terminal of the CPU 23 through a power amplifier 24 as the control signal of the motor 15, When the mode of the motor becomes low-speed mode, the CPU 23 utilizes both of the leading edge signal and the trailing edge signal of the pulse of the encoder as the rational frequency signal for the motor.

Filed: 1986-04-28
Abstract: PURPOSE:To attain the high accuracy in paralleling by detecting marks on at least three points of a mask and a wafer while keeping the mask and the wafer in one and the same position without moving. CONSTITUTION:A contrast quantity of marks 23 of a mask 29 and a wafer 1 is detected by a detecting means and an air pressure is applied to an air pressure chamber 16 under a leaf spring 4, this leaf spring 4 is bent by its pressure accepting area and the air pressure and further a leaf spring 8 also bends.

Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To obtain a substrate treatment equipment which can restrain generation of dust as little as possible when a substrate is carried in a cassette and carried out from it, and improve quality of substrate treatment. SOLUTION: A plurality of cassettes C storing substrates W on multistage are statically mounted on a cassette mounting stand 3. Substrate taking-out mechanism 4 which moves along cassette mounting stand 3 is elevated, thereby taking out a substrate W from the cassette C. The substrate W is subjected to centering, and then delivered to a substrate transfer mechanism 9. A second transfer route wherein the substrate transfer mechanism 9 moves in both directions stretches in the rectangular direction from the center of a first transfer route wherein the substrate taking-out mechanism 4 runs. The substrate transfer mechanism 9 moves on the second transfer route and carried the substrates W to each substrate treatment part. When the substrate W is carried in the cassette C and carried out from it, the cassette C does not move so that generation of dust due to vibration of the cassette C is restrained.

Abstract: PURPOSE: To conduct correspondence between stereo images, to decide a parallax of the stereo image with an arithmetic amount as less as possible and to absorb an error caused by corresponding. CONSTITUTION: Two image pickup devices obtain left and right images in the image pickup phase (A) (S101, S102).

In the corresponding phase (C), a window being the unit of correspondence is set sequentially by scanning a linear window according to a scanning rule on one referenced characteristic image and the correspondence is conducted with the other characteristic image for each set linear window.  Next, in the parallax decision phase (D), the one reference characteristic image is divided into blocks of a size and a histogram is generated by using the parallax obtained by the correspondence of the linear window including the picture elements of each block and, for example, a parallax at each peak position is sued for a block parallax (S106).

Abstract: PURPOSE: To obtain a unit which is safe and can extend the life of an optical scanning equipment, by driving and controlling the optical scanning equipment so that optical scanning may be performed in the light shielding part other than the scanning visual field with a scanning width narrower than that for scanning in a low scanning speed for optical scanning waiting, in the scanner used for a scanning type electronic copying unit and so on.

Consequently, the laser beam is prevented from being leaked to the external and entering eyes of the worker for exchange of original 14. Since driving of driving coil 18a in this scanning waiting state is so set and controlled that the rotation speed may be lower than that of read scanning of original 14 and the scanning width may be narrower, the load for driving coil 18a can be small, so that the mechanical life of driving coil 18a can be extended.

One of these webs is angled away towards the optical axis in such a manner that its upper edge forms the diaphragm edge generating the light/dark boundary. The other webs form the support arms of the frame. <IMAGE>
