Abstract: PURPOSE:To laminate a silicon single crystal layer easily as well as speedily, by  making ionized vapor particles having a kinetic energy of 1-10<4>eV bombard against a  substrate at an incident angle of 0-30 deg. or 75-89 deg. with respect to the normal thereof. CONSTITUTION:Silicon 17 is supplied into a crucible 7, and evacuation is effected  through an evacuation port 2 in order to bring the inside of a vacuum chamber 1 under  a high vacuum. In addition, power sources 14, 15, 16 are placed therein. Then, while  cooling water is being supplied to a water-cooled copper hearth 9, a 180 deg.-deflected electron gun 8 is actuated to heat the silicon 17. The silicon 17 is vaporized to reach a  vapor ionizing section 6. As a filament 10 is energized to heat up by means of the  power source 15, thermoelectrons are emitted. The thermoelectrons are field-accelerated to collide against the vapor of the silicon 17 thereby to ionize the same to be positively charged. The ionized vapor particles are provided with a kinetic energy of  1-10<4>eV by means of the power source 14 so as to collide against a substrate 5. In  this case, the substrate 5 is disposed so that the ionized vapor particles will be made  incident on the substrate 5 at an angle of 0-30 deg. or 75-89 deg. with respect to the normal  thereof, thereby allowing a single crystal layer to be formed on the surface of the substrate 5.

CONSTITUTION:A light screening plate 4 and a condenser lens 5 are provided on the light receiving axis of a sensor 1 in front of the sensor 1. In the light screening plate 4, a window hole 4a forming an incident angle theta which is twice a slant angle theta of the surface roughness of a material to be inspected 2 is opened. The projected light which is inputted through the window hole 4a is condensed on the light receiving surface of a line sensor 1 with the condenser lens. Even if the scanning direction of the light receiving part of the sensor 1 becomes oblique with respect to the lateral direction of the material to be inspected 2 and waving is present in the longitudinal direction on the surface of the material to be inspected 2, the reflecting angle at the observing point of the sensor 1 shown with broken lines becomes the minimum and maximum values at slant angles (a) and (c). The region between the minimum value and the maximum value becomes about twice the slant angle theta. Therefore, when the reflected light within said region is received with the light receiving surface of the sensor 1, the detected output of the received light of the sensor 1 is not dispersed, and the waving of the detected output of the received light can be decreased.

Title: Paper feeder in printer with automatic paper supply device
Inventor: TAKAHASHI KIYOSHI
IPC: B41J13/00
Filed: 1985-05-07
Abstract: PURPOSE:To prevent a paper from jamming, by a method wherein when a comulative reverse paper feed quantity is larger than a predetermined reference value under the condition where the trailing end of a printing paper is located on the automatic paper supply device side of a branching part of a guide passage, the paper is fed forward until the trailing end thereof is passed through the branching part. CONSTITUTION:In this example, the paper feed quantity per one printing line is 1/6 inch. When the trailing end of the printing paper 16 is located on the automatically paper supply device 11 side on the upstream of a point A, a CPU calculates the cumulative reverse paper feed quantity. At this time, the cumulative reverse paper feed quantity is zero, so that the subsequent reverse paper feed quantity is the cumulative reverse paper feed quantity. When the reverse paper feed quantity is 1/3 inch, which is larger than the predetermined reference value, the CPU feeds the paper forward until the trailing end of the paper 16 is passed through the point A. The CPU then feeds the paper 16 reversely by the same amount as the forward paper feed quantity, thereby leading the paper 16 to a guide passage 33 for rearward paper feeding, and feeds the paper rearwardly by a two-line amount, without generating paper jamming.
