IPC: G03G5/08
Filed: 1980-06-25
Abstract: PURPOSE: To use inexpensive silicon for a photoconductive layer and to enhance abrasion resistance, by forming a first layer made of a P- or N type semiconductor and on this layer a second layer made of a true or substantially true semiconductor.  
     CONSTITUTION: A photoconductive semiconductor 2 consisting of a first layer made of a P type semiconductor and a second layer made of a true or substancially true semiconductor is formed on a conductive substrate 1. A semiconductor consisting of silicon or a silicon-nitrogen compound containing impurities in high concentration is used for this P type semiconductor. When positive charge is attached to the semiconductor 2 from a static charge generating source in this structure, and the semiconductor 2 is exposed to light 5, the static charge on the exposed parts 6, 6' is released to the substrate 1, and negative electrons neutralizes the positive charge, forming an electrostatic potential pattern on the semiconductor 2. Fabricating such a structure on the surface of a rotary drum permits a copy similar to conventional ones to be made, inexpensive silicon to be used, and abrasion resistance to be enhanced.

Title: Operating method for cross flow water turbine
Inventor: SOMA HIROSHI
IPC: F03B1/00
Filed: 1985-04-23
Abstract: PURPOSE:To increase an effective head and to increase the efficiency of a water turbine, by a method wherein the runner of a cross flow water turbine is operated in a state to be completely sunk in water. CONSTITUTION:When the runner of a cross flow water turbine is completely sunk in water, an effective heard He is determined by a formula of UWL-TWL-Hloss, wherein UWL is an upper water level, TWL is a tailace water level, and Hloss is a loss head. This causes a relation between a central position MEL of the water turbine and an effective head to be rendered ineffective, and enables substantial increase of the effective head.

Abstract: PURPOSE:To accomplish the prescribed adjustment in the prescribed area by judging the direction of an installed test chart when the automatic adjustment of a color balance is executed with the aid of non-object test chart. CONSTITUTION:A center area where markers with + marks on a test chart 1 are arrayed is specified in the action start condition. Then an area at left side from the center area is specified by a window pulse phiw. A level of a green video signal EG which has been processed in the area is compared with that of a reference voltage 33 by a comparator 31, and its output is supplied as data to an arithmetic processing circuit 38 through an A/D convertor 35. Based on the data the circuit 38 decides whether or not the area to be specified is modified. Namely, when a level of the EG supplied to the comparator 31 is higher than that of the voltage 33, the area is decided to be a white one. If the level is lower, the area is decided to be a black one.

Abstract: PROBLEM TO BE SOLVED: To inexpensively improve the judgement of authenticity by judging the authenticity of paper money or the like by the combination of authenticy judgement based on the comparison of all read data of inserted paper money or the like and authenticity judgement based on the comparison of data worked from the read data. SOLUTION: The authenticity of paper money or the like is judged by combining plural judging methods. When three kinds (I to III) of paper money or the like, four kinds (A to D) of inserting methods are prepared, candidates I-A, I-C, II-D and III-C in a judging method 1, I-A and II-C in a judging method 2 and I-A, I-B and III-C in a judging method 3 are respectively judged, the candidate I-A is judged as an authentic object. When two or more candidates are obtained, authenticity is judged by majority, and there is no candidate, the object is judged as a forgery. Since processed data are used, candidates are converted at first by a judgement method capable of judging the characteristic part of the paper money or the like by the small number of comparing data and finally all patterns are compared and judged to shorten processing time.

Filed: 1984-04-28
Abstract: PURPOSE:To select reading of high resolution and low resolution economically by arranging the reading side end parts of light emitting side fibers straight at fixed array pitches and adjacently arranging the photodetecting side end parts of the photodetecting side fibers in parallel with the array of the light emitting side fiber end parts at pitches shifted by a half of the pitch of the array of the reading side end parts of the light emitting side fibers. CONSTITUTION:The reading side end parts 15 of thirteen light emitting side fibers T1-T13 are straight arranged at the fixed array pitches and twelve photodetecting side fibers R1-R12 are shifted almost by a half of the pitch at the reading side end part 17 so as to be parallel with the array of the reading side end parts 15 of the light emitting side fibers, so that 24 reading points on the original surface can be read out with high resolution. Since the ON/OFF of the light emitting elements L1-L13 is controlled with time division, a reading head 1 can read out high resolution and low resolution. The low resolution reading attains rapid reading as compared with high resolution reading.

IPC: E02F9/12
Filed: 1994-03-31
Abstract: PURPOSE:To prevent high pressure water from entering the inside from a lip part of a turning seal of a turning bearing for hydraulic shovel at the time of car washing. CONSTITUTION:A recessed, stepped part 22 is provided along the inside periphery of the underside 21 of an outer ring 20 fixed to an upper turning body. A lip part 15 of a seal 14 fitted into a groove 13 provided in an inner ring 20 fixed to a lower travelling body 2 is allowed to abut against the bottom face 23 of the stepped part 22. Since high pressure water directly hits the underside 21 of the outer ring 20 to flow as indicated by the arrow when a car is washed, the water does not directly hit the lip 15, and the lip is turned to the stepped part by the high pressure water to prevent the water from entering the inside of the bearing.
