Title: Method for detecting posture of installed stem
Inventor: YASHIRO MASAKAZU
IPC: H01L23/02
Filed: 1988-03-30
Abstract: PURPOSE:To enable detecting a wrong installation posture of a workpiece by connecting a vacuum circuit to operate a vacuum sensor only when a cylinder actuated absorption pad stops a lower electrode unit at the specified position. CONSTITUTION:The dividing operation of an index table 3 moves a workpiece comprising a stem 5 inserted into a stem guide 11 of a lower electrode unit 4 and a metal cap 6 from a position D-D to a position B-B. The index table 3 stops its rotation at this position, and at the same time a vertically reciprocatable cylinder 19 rises to bring a piping block 18 and an absorption pad 17 both installed at the tip of a cylinder rod into contact with the lower end face of a lower electrode holder 13 for completing the connection with an evacuation system 26. If the posture of the installed workpiece is proper, the vacuum sensor confirms the proper posture by obtaining the degree of vacuum higher than a specified value. This enables detecting an improper installation posture such as the complete stranding on or the gradient in the stem guide.

Title: Image reader and image copying machine using the same
Inventor: KAWASAKI SHIGERU
IPC: H04N1/401
Filed: 1994-03-26
Abstract: PURPOSE:To eliminate uneven shading correction due to an optical path length difference between an original platen glass and a shading plate by providing the shading plate at a position equivalent optically to an original face with respect to an image forming optical system via a transparent member. CONSTITUTION:A shading plate 123 is placed on a transparent member 124 made of a dummy glass having the same refractive index and the same thickness as those of an original platen glass 122 to make an optical distance of the plate 123 and an original face 121 with respect to an image optical system 125 or a CCD 126 equivalent to each other. Thus, in the case of shading correction, a reflected light of the plate 123 with a uniform density being a reference against uneven lighting of a light source 115 in the main scanning direction is detected by the CCD 126 and a coefficient for correcting an output difference between the edge and the middle part is calculated. Since the optical distance between the plate 123 and the original face 121 is made equivalent, no luminance distribution difference between the plate 123 and the original face 121 is not caused. Moreover, since a correction coefficient is multiplied by an output of the CCD 126, uneven lighting is corrected and the shading is completely corrected to read image data without uneven color.

Title: Reversible counter
Inventor: YOSHIDA SUMIO
IPC: H03K23/00
Filed: 1979-06-27
Abstract: PURPOSE:To constitute a counter whose dividing ratio is expressed by one ''even number''-th with a small number of control elements by detecting the set state and fixed count-value state of a counter and then by exercising up-down control over the counter with a level signal based upon the detection result. CONSTITUTION:Reversible counter 2 counts clock pulses CP and its count direction is brought under the control of RSFF1. Fixed count value detecting circuits 3 and 4 detect the contents of counter 2 reaching a fixed count value and with their detection signals, FF1 is brought under set-reset control. In this case, pulse removing circuits 5 and 6 remove the error detection of circuits 3 and 4 due to difference in timing. Now, when counter 2 is to operate at dividing ratio 1/14, circuit 3 sets FF1 on detecting count value ''0'' and then counter 2 counts up; and circuit 4 resets FF1 on detecting count value ''7'' and counter 2 is brought under switching control to count down, counting up and down cyclically between ''0'' and ''7'', so that the counter will eventually operate at a division ratio of 1/14.

IPC: H04B10/00
Filed: 1989-03-30
Abstract: PURPOSE:To stabilize the quality of a transmission signal by providing a light transmitter and a single mode fiber transmission system to transmit the output of the light transmitter on which a countermeasure for reflected light is applied. CONSTITUTION:Light transmitted by a fiber 12 for transmission is introduced to a light receiver 101. The light receiver 101 is comprised of a photodetector 13 which performs the photoelectric conversion of reception light and a low-noise amplifier 14 for amplification. The output terminal of the fiber 12 for transmission is coupled directly with the photodetector 13 by using a diagonal grind connector 15, and the plane of the final output terminal coupled with the photodetector 13 is formed obliquely against the optical axis of the fiber. By employing such structure, it is possible to couple the reflected light generated at the end face of the fiber with the photodetector without returning to an LD. In such a way, the quality of the transmission signal can be stabilized.
