Title: Wafer positioner
Inventor: KOSUGI MASAO
IPC: G05D3/00
Filed: 1979-11-05
Abstract: PURPOSE: To improve accuracy when positioning the wafer by a method wherein a driving roller is operated as a driven roller with smaller torque when terminating the driving of the wafer to rotate it.  
     CONSTITUTION: The wafer 20 is caused to float by air jetting out of skew hole 28 made in the wafer and rotate by driven and driving rollers 24, 23. Simultaneously, the pressure of a cylinder 32 is released to thrust a roller 29 upon the wafer. The roller 23 is so arranged that it is located in a slightly backward position from the tangent line touching rollers 25, 26 for positioning both sides of the wafer. The torque of the roller 23 is given to the rollers 25, 26 via idlers 27, 28. The torque of the rollers 24W26, 29 is small. When the wafer that is being turned approaches the position for locating itself, a cylinder 29 is operated after photodetecting the position 40 in order to separate the roller from the idlers and position the wafer finally on the tangent line touching the rollers 25, 26. Then the cylinder 32 is operated to allow the roller to hold the wafer and complete the positioning of the wafer by means of the sucking force of the hole 28.

Title: Color image recorder
Inventor: NAKAI HITOSHI
IPC: G03G15/01
Filed: 1987-06-09
Abstract: PURPOSE:To reduce the production cost of an exposure light source for color image by using a photosensitive material where a photosensitive layer consisting essentially of a titanium dioxide and a binder is laminated on a conductive base material and exposing this photosensitive material by the exposure light source consisting of a CRT which has the intensity of light at least in 400-420nm wavelength range. CONSTITUTION:Since a photosensitive sheet S formed by coating an TiO2 and a binder on the conductive base material has the very high degree of whiteness by finely powdering the TiO2 itself, the influence of the foundation color of a photosensitive layer supporting body including the conductive layer is almost completely eliminated. The spectral sensitivity of the TiO2 has a peak in the range of lambda=400-420nm, and a material which has a light-emission intensity distribution in the range of lambda=400-420nm where the TiO2 has a peak of sensitivity is relatively easily obtained with respect to the phosphor of a line type CRT 9 which exposes the sheet S on the drum 6. Since the same light-emission wavelength of the exposure CRT is used for R, G, and B, the cost is reduced by the common use.

Abstract: PURPOSE:To detect accurately the degradation of the ultrasonic wave generating function by comparing a measured calorific value with a set reference value. CONSTITUTION:A temperature detector 9 which measures the calorific value of a power transistor TR8 of an ultrasonic oscillating circuit is provided, and the difference between the calorific value measured by the detector 9 and the value detected by an atmosphere thermometer 10 is calculated by an ultrasonic wave generating function discriminating circuit 11.

Filed: 1992-05-08
Abstract: PURPOSE: To enable a laser system to be tuned in a wide range of frequencies by a method, wherein an average propagation direction is determined so as to automatically determine the length of a laser cavity in a distributed feedback system. CONSTITUTION: The propagation direction of a laser output beam 6 is detected by a propagation detector 18 in an SLM laser system 2, where a laser resonator is automatically varied in length. The propagation detector 18 (or 18') feeds its detection signals to an SLM processor 20. At this point, the propagation of a distributed beam 16, determined based on the sampled detection signals is analyzed statistically. An average propagation direction is compared with the present value of the propagation angle of the distributed beam 16, and a position changer 22 is operated, so as to change the position of a rear mirror 8 which is proportional to a difference between the average propagation direction and the present propagation angle. By this setup, a laser cavity 4 is varied in length.  The position of the rear mirror 8 is changed so as to make a difference between the average propagation direction and the latest measured value of a propagation angle negligibly small.

Filed: 1983-08-09
Abstract: PURPOSE:To suppress the irregular rotation of a DC motor at the constantly rotating time by lengthening the pulse width modulation synchronization at the constantly rotating time as compared with that at the rising time. CONSTITUTION:A CPU3 inputs an output from an encoder 1 through a rotating direction detecting waveform forming circuit 3, calculates the detected result of speed and rotating direction, outputs a control amount to a programmable counter 4, and applies a trigger to the counter 4. As a result, the counter 4 outputs a pulse of the pulse width proportional to the control amount to a motor driver 5. The driver 5 supplies a current to a DC motor 1 during a time proportional to the pulse width in accordance with the rotating direction. Then, the CPU3 controls to shorten a trigger interval at the rising time and to lengthen at the constantly rotating time. Thus, the irregular rotation at the constantly rotating time can be suppressed to low value.
