Inventor: ITAGAKI MAKOTO
IPC: G02B21/00
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To vary light absorptivity and make the absorptivity of the phase plate continuously variable, and to improve the contrast of an image by placing a variable absorptivity absorber, which has a variable absorptivity light absorbing material varying the absorptivity, on the pupil conjugate surface of an objective.

This light absorber 6 is a variable absorptivity light absorber having the variable absorptivity light absorbing material which varies in the absorptivity according to an externally supplied electric signal and is placed on the pupil conjugate surface of the objective. Since the quantity of absorption of the direct light passed through the phase shift body 7 can be varied continuously thereby, the direct light can be made to have desired intensity, and the contrast of the observed image can be improved.  Further, the variable absorptivity light absorber 6 can be arranged in common to an objective of different power by placing the variable absorptivity absorber 6 on the pupil conjugate surface of the objective.

Title: Electrophotographic device
Inventor: SHIMADA AKIRA
IPC: G03G15/16
Filed: 1990-09-07
Abstract: PURPOSE:To prevent jamming and to carry out a transfer and separation without damaging photosensitive body and the top end of a separating nail by abutting the top end of the separating nail on the surface of the photosensitive body by means of electrostatic force acting between the electrifying charges of the separating nail and the photosensitive body. CONSTITUTION:A high voltage power source 15 applies a high-voltage on the to end part of the separating nail 14 to electrify the separating nail 14. Attracting or repulsing electrostatic force acts between the separating nail 14 and the photosensitive body 1 by the electrifying polarity of the separating nail 14 and the polarity of the electrifying charge of the photosensitive body 1. The top end of the separating nail 14 is abutted or removed to or from the surface of the photosensitive body 1 by the electrostatic force. The abutting or removing action is carried out in synchronization with the travelling of a sheet 5, so that the sheet 5 which is adhered to the photosensitive body 1 and carried up to the separating nail 14 caused by a failure in separating from the photosensitive body 1 in the vicinity of a transfer position A, can be surely removed form the photosensitive body 1, on the separating nail 14. Thus, even if the sheet is deformed, it can be surely separated without having the jamming caused by the winding of the sheet to the photosensitive body 1.

IPC: H04L27/12
Filed: 1984-11-07
Abstract: PURPOSE:To keep a frequency shift of an output signal to a constant value by feeding back an output level of an FM modulation means using a part of an output of a VCO to a voltage control ATT controlling a data signal level. CONSTITUTION:A part of an output of the VCO 23 is extracted by branching devices 24, 28 and inputted to a mixer 36. The mixer 36 mixes an output of a frequency synthesizer comprising a VCO 40 of PLL constitution and an output of the VCO 23, and the output is detected by an FM detector 38 through a BPF 37, the detected output is rectified by a rectifier 48 and the result is input ted to the voltage control ATT 21 as a control voltage signal 39. The oscillating frequency of a VCO 40 is set by using a frequency dividing ratio data 47 offset ting a frequench division ratio data 31 deciding the oscillating frequency of the VCO 23 by a certain value. Since a signal branched from the VCO 23 is subjected to FSK modulation by using an input signal 18, the output of the detector 38 is a detected output in response to the frequency shift of an FSK, the attenuation of the ATT 21 is controlled depending on the output of the signal 39 to make the frequency shift of the output signal 27 constant.

Title: Information recording system
Inventor: IIDA ATSUKO
IPC: G11B7/2433
Filed: 1986-10-06
Abstract: PURPOSE:To reduce the size and cost of a recording and reproducing device by projecting the laser light corresponding to a signal to a thin film essentially consisting of opaque low oxide of nickel thereby recording information. CONSTITUTION:The laser light corresponding to the signal is projected to the thin film essentially consisting of the opaque low oxide of nickel to form the image. The low oxide of nickel refers to a material expressed by NixOy (0<y/x<1) and is an n-type semiconductor which is usually dark brown. The transmittance of visible light of the low oxide film of nickel is larger as the value y/x approaches 1. The film having a large degree of black color in the region where x/y is relatively approximate 0 is oxidized by the heat energy of the laser light corresponding to the signal to the state in which y/x is 1 or nearly 1, by which said film is made transparent. Writing of the signal by the laser light is executed by converting the thin opaque low oxide film of nickel to transparent nickel oxide by thermal oxidation. For example, a semiconductor laser 1 of GaAlAs, etc., having 780nm is used. The reading is executed by projecting lower output light using the same laser.

IPC: G05D13/62
Filed: 1994-09-30
Abstract: PURPOSE: To provide a rotary body controller which stops a rotary body and eliminates unnecessary power consumption when there is no hindrance. CONSTITUTION: A system control circuit 103 which judges that there is no trouble even if a cylinder 1 is stopped once an eye sensor 101 detects nobody peeping into a finder, and then makes a rotation control circuit 102 to stop the cylinder, thereby eliminating the unnecessary consumption of the power source 10. When the eye sensor 101 detects there being a person who peeps into the finder, it is considered that the cylinder 1 needs to be rotated, and the cylinder 1 is then rotated to eliminate the time required to actuate the cylinder 1, thereby preventing the operability from being spoiled. Consequently, the unnecessary consumption of the power source is eliminated and the use time of the rotary body controller is prolonged.

Title: Collision preventing device for traveling vehicle
Inventor: IKEDA MASAHIRO
IPC: G05D1/02
Filed: 1988-09-21
Abstract: PURPOSE:To simplify the constitution of a collision preventing device while setting a transmission/reception range of the electromagnetic wave serving as the traveling vehicle existence signal by folding a loop antenna at the corner parts of the vehicle body at the front and back traveling sides respectively. CONSTITUTION:The bumpers 8 are attached at a vehicle A traveling along a guide line L at the front and back sides and over the both side parts of the body of the vehicle A. The loop antennas 9 are folded at the corner parts of the vehicle body and stored into both bumpers 9 to transmit and receive the electromagnetic waves of the set frequencies serving as the traveling vehicle existence signals. In this case, however, each antenna 9 is divided into the right and left parts approximately at the center of the width of the vehicle body. Thus these right and left antennas can transmit and receive the different electromagnetic waves. As a result, the transmission/reception range of electromagnetic waves can cover continuously the front and back traveling sides and also can be set at the sensing range for existence of the vehicle A with high accuracy.
