Title: Relative angle detection device
Inventor: SAITO JUNICHI
IPC: G01B11/26
Filed: 1994-12-08
Abstract: PURPOSE: To prevent saturation of an amplifier when a large quantity of light enters by enabling a control part to calculate relative angle data, calculating coordinates expressed by the data, and at the same time, supplying a gain setting signal and suppressing the output voltage of a plurality of current/voltage conversion parts. CONSTITUTION: A control part 14 successively switches a selection switch 9 to channels 1-4, reads relative angle data from an A/D converter 13 for each switching, and obtains the inclination angle in X-axis and Y-axis directions of a portable input device 5 based on the data. Then, coordinates on XY coordinates on the display surface of a CRT 3 are obtained from the angle and are transmitted to and displayed on a CRT 3 via a light signal transmission part 16 and a light reception part 4. A control part 14 generates a gain setting signal based on the relative angle data and sends it to current/voltage converters 8a-8d.  The converts 8a-8d increase and decrease the conversion gain in response to the gain setting signal according to the quantity of incidence light of split light reception parts 6a-6d and the output voltage is always limited to a specified range, thus preventing a succeeding variable gain amplifier 10 from being saturated.

Filed: 1989-11-27
Abstract: PURPOSE:To attract even curled sheets due to heat or environmental change, certainly by furnishing a partitioning member in a vacuum chamber, wherein the partitioning member is arranged to raise the suction pressure toward the transport direction. CONSTITUTION:Sheets A are stacked neatly without bouncing in the axial or in the transport direction, and are attracted to a suction belt 22 which is set in such a way as enwrapping the peripheral surface of a vacuum chamber 21.

CONSTITUTION: A range difference ΔL between the position of an operator and that of a moobile device is equal to an amount of elongation in a transfer member. This range difference ΔL is multiplied by a speed proportional constant Kv, thereby securing a speed control output (mobile device speed). Simultaneously with this, the range difference ΔL is multiplied by an acceleration proportional constant Ka, thereby securing an acceleration control output (mobile device acceleration) after being integrated. In succession, either of the speed control output or the acceleration control output is selected by a selector switch, outputting it as a speed control command. With this constitution, the labor alleviation and operation efficiency uplift of the operator are well promotable.
