Title: Sheet classifier
Inventor: SHIROHAMASE REIJI
IPC: B65H39/11
Filed: 1979-11-07
Abstract: PURPOSE: To provide a compact and simple device by vertically swingably supporting trays and a tray box and displacing the trays through the use of a sector cam.  
     CONSTITUTION: Each tray 202 is provided with a hinge shaft 230 and pin 231, while a tray box 200 is provided with a hinge receiver 228 and a receiver metal 229, and the tray 202 and the tray box 200 are supported vertically swingably. As a table 207 descends and the tray 202 approaches a receiving position, a sector cam 18 and the pin 231 contacts each other, the position of the tray 202 relative to the box 200 is displaced upward, and copying paper is received on the lower next tray 202. Because the tray box and the trays 202 are displaced by a single mechanism utilizing the sector cam 108, the classifier can be compact and simple.

Title: Method and equipment for measuring distance
Inventor: ARAI IKUO
IPC: G01S13/10
Filed: 1993-05-24
Abstract: PURPOSE:To allow online operational measurement by shortening the time of corrective operation for determining a highly accurate distance value through correlation of measured distance values and shift measured values. CONSTITUTION:A measured distance value up to a target E is determined by receiving a repetitive pulse wave transmitted from a distance measuring section 1 at a predetermined period. The measured distance value is determined based on the time to be elapsed between a specified point of a transmission pulse wave and a specified point of a receiving pulse wave. Measured shift amount is determined every moment at the position of a target E by transmitting a continuous wave at a predetermined frequency from a shift measuring section 2. The measured shift amount is determined based on the difference between transmission frequency and receiving frequency. A corrective distance value operating section 3 solves an equation Rc='R(i)'='R(0, i)'+r(i); where, R(0) is an initial measured distance value, R(i) is every time measured distance value, r(i) is every time measurement shift value, Rc is corrected distance value, and 'R(0,i)' is an estimated measured distance value for minimizing the square sum of error. Since the method of sequential least squares is used for convergence long operation, e.g. equation of Kalman filter, is not required thus shortening the operating time significantly.

Title: Method and equipment for determining position of surface
Inventor: KORUNERISU MARINUSU HENDORIKUS
IPC: G01B11/02
Filed: 1990-06-04
Abstract: PURPOSE: To determine the position of a surface spaced apart slightly from the starting point of a focus or disposed closely to another surface by setting the amplitude of the periodical movement of an objective mirror system deeper than the focal point of a converging objective mirror. CONSTITUTION: A radiation beam 21 is focused through a converging objective mirror 30 at a focal point 22 in the vicinity of a surface of which the position must be determined. A part of the radiation is reflected on the surface and projected onto a high sensitivity radiation detection system 50 through an objective mirror 30 and splitting cube 40. The distance between the focal point 22 and the surface is varied by moving an objective mirror system up and down through an electromagnetic actuator of a coil 31 disposed around a magnet coupled with the objective mirror 30 and thereby the output signal from the system 50 is modulated.  The position of the surface is determined by moving the surface and the average position mutually until the amplitude of periodic up/down movement exceeds the depth of local point of the objective mirror 30 and the maximum amplitude of a modulated signal is obtained.

Filed: 1988-06-13
Abstract: PURPOSE:To enable a high-speed atomic line to have high convergent quality approximately equal to the inner diameter of a nozzle by generating the high- speed atomic line within the ion neutralizing nozzle of the first cathode and emitting the line from the nozzle to the outside. CONSTITUTION:An electric discharge takes place in a gap between a needle- shaped anode 21 and an ion neutralizing nozzle 23 and a glow is thereby generated. An ion grown via the aforesaid glow discharge is accelerated toward the nozzle 23 and enters therein. A gas is being supplied to the nozzle 23 and upon contact with the gas, the ion loses an electric charge and returns to a neutral atom. In this case, the kinetic energy of the ion is taken up by the neutral atom without any change, turns into a high-speed atomic line and is emitted outside from the nozzle 23. According to the aforesaid construction, the high- speed atomic line emitted from the nozzle 23 is converged approximately to the inner diameter thereof and comes to have high convergent quality.
