Filed: 1982-12-28
Abstract: PURPOSE:To maintain electrical and optical characteristics always constant by forming a blocking layer between a substrate and a photoconductive layer made of microcrystalline silicon or a layer of a mixture of amorphous and microcrystalline silicons or laminate layers of both. CONSTITUTION:Amorphous silicon exhibits no X-ray diffraction, but microcrystalline silicon does a crystal diffraction pattern at 27 deg. angle. Polycrystalline silicon has <=10<6>ohm.cm dark resistivity, but microcrystalline silicon has >=10<11> dark resistivity. Microcrystalline silicon is presumed to consist of fine crystals having several nm diameter. The electrophotographic sensitive body of this invention can be formed on a substrate from microcrystalline silicon likewise from amorphous silicon, and film forming speed can be raised by holding the temp. of the substrate 21 to >=350 deg.C and increasing the feed rate of a starting material of gas. A blocking layer 22 prevents injection of carriers from the side of the substrate 21 to the photoconductive layer 23. Since this electrophotographic sensitive body of this invention is superior in heat and abrasion resistances, it is not deteriorated even long term repeated uses and long in life.

Title: Picture reader
Inventor: NAKAJIMA AKIO
IPC: H04N1/04
Filed: 1987-09-10
Abstract: PURPOSE:To eliminate the slippage of an original tip position due to a variable power by detecting the tip position of a pattern scanning direction of a pattern plate through the use of a scanning means and a picture reading means. CONSTITUTION:By being synchronized with a CCD9 shift signal SH, a line RAM writing signal is outputted, data are written in a line RAM 50, and by being synchronized with the next shift signal SH, the output of the line RAM writing signal is stopped. Next, an optical system is judged to reach a pattern 16a when black data are detected concerning a picture element in the center + or -100. First, an address for the line RAN 50 pointer is set to median the inverse of 100 by being synchronized with the shift signal, the address is increased one by one, and when the black data are detected, the optical system is judged to reach a central focusing detecting pattern 16a. Namely, since a distance from the pattern to an original tip position is already known, it can be recognized that the optical system reaches the original tip when the optical system (slider) is moved for the distance. Thus, the slippage of the original tip position due to machine dispersion can be eliminated.

CONSTITUTION:While raisins the whole back reset part 3, it is turned in front of a chair. In this case, a takeout part 10 turns centering around a pivotally supporting shaft 9', and turns in a circular arc groove 7, therefore, the back rest part 3 connected to the takeout part 10 through a fitting part 11 also turns along a circular arc locus centering around the pivotally supporting shaft 9'. When the back rest part 5 is moved to a horizontal position in which the upper face 3a having no cloth of the back rest part becomes a horizontal state in the upper part of a seat part 1 by tuning the back rest part 3 by about 90 deg., the takeout part 10 abuts on the upper end edge 7a of the circular arc groove 7, and further turning of the back rest part 3 is obstructed. Subsequently, a stopper 5 is inclined and laid down in front of the chair, and a gap generated between a frame body 4 and the back rest part 3 in a horizontal position is closed up. The chair whose back rest part is held in a horizontal position functions as a table, and it becomes a bed by enlarging the back rest part 3.
