Title: Image forming method
Inventor: SHIMIZU AKIRA
IPC: G06K15/00
Filed: 1985-05-21
Abstract: PURPOSE:To compensate the distortion of an image due to skew of a recording paper accurately with a simple constitution without requiring mechanical driven parts by shifting the image forming position on a recording head in the direction of dot lines in accordance with the positional deviation between the recording head and an image receiving member viewed in the direction of dot lines. CONSTITUTION:A controller 45 is provided with a counter to count the number of dot lines, and a programmable counter is provided and its initial value is set in accordance with a maximum distortion extent DELTAd of the image. Each time the dot line counter counts 100 dot lines, one is subtracted from contents of the programmable counter. Contents of the programmable counter are supplied to a deskew circuit 43, and the timing is controlled when a dot picture signal supplied from a character generator 42 is written in a buffer memory consisting of a random access memory provided in the deskew circuit 43. If the image on a recording paper 17 is deviated right, the write timing of the dot picture signal is shifted left by an extent corresponding to one dot at intervals of 100 dot lines.

Title: Finely adjusting mechanism
Inventor: NOSE HIROYASU
IPC: G12B5/00
Filed: 1989-05-01
Abstract: PURPOSE:To realize a finely adjusting mechanism which is adapted to prevent inclination of a horizontal plane of a sample stage and to prevent vertical twisting thereof by supporting a mobile member carrying the sample stage with an elastic member to press it with a piezo-electric element through a linear guide mechanism. CONSTITUTION:When a voltage is applied to an x-wise piezo-electric element 2 to stretch it in a direction (x), a mobile member 3 moves in the direction (x) through a pole 5. At this point, as the member 3 is supported with four elastic members 6, it moves keeping horizontal and hence, will not be inclined. The member 3 will not shift in a direction (y), as it is guided with the element 2, a guide member 4 and the pole 5. Likewise, when the member 3 is moved in the direction (y), it is guided linearly with the x-wise element 2, the member 4 and the pole 5 keeping horizontal and thus, can be moved without shifting in the direction (x).

Title: Operation system in adjustment of picture information reader
Inventor: OGASAWARA FUMIHIRO
IPC: H04N1/32
Filed: 1979-08-30
Abstract: PURPOSE:To make it possible to take out a video signal cheaply and simply while stopping the read head still, by providing a signal generating circuit, which generates the read start signal, separately from the picture information reader and by connecting this circuit to the picture information reader at an adjustment time. CONSTITUTION:At an adjustment time for the picture information reader, signal generating circuit B is connected to picture information read circuit A, and switch SW2 is switched from the position shown in the figure to the opposite position. At this time, if circuit A is fitted to the reader, switch SW1 holds the state of the position shown in the figure because the input of clock (f) is held. Then, input clock (f) is converted to scanning clock fa and is input to not only driving circuit 14 but also programmable counter 17 of circuit B. At this time, if switches SW11-SW1N are set properly, read start signal sb can be generated at the same timing sa signal as generated from synchronizing circuit 13. Consequently, when signal sb is input to circuit 14, the same video signal as the normal read operation can be output while stopping read head 2a still.

Title: Electrophotographic method
Inventor: AOKI KENJI
IPC: G03G15/04
Filed: 1979-08-29
Abstract: PURPOSE:To form an image of high resolution free from background stain by charging an electrostatic recorder, attaching a photoconductive toner to the recorder, imagewise exposing the recorder, and simultaneously applying AC corona discharge. CONSTITUTION:Electrostatic recorder 8 is charged with corona charger 7, and photosensitive toner 2 is attached to recorder 8 by scattering toner 2 through sieve 9, or doing the like. Toner 2 is imagewise exposed with optical system 14, while it is subjected to AC corona discharge at the same time with AC corona charger 13. At that time, since the toner 2 layer acts as an insulating layer in the dark 17, the charge on recorder 8 does not decrease, retaining the attachment force strong. On the other hand, since the toner 2 layer in the light 18 acts as a conductor, the AC corona current reaches the recorder layer 8, releasing all the accumulated charge and all the attachment force.

Title: Ophthalmologic photographic apparatus
Inventor: MATSUMOTO KAZUHIRO
IPC: A61B3/14
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To observe an optical image of an eye to be examined and an image taken by a photographic means without moving the photographer's eye. SOLUTION: After confirming the appearance of fluorescence, a photographer operates an observation switch 8 to photograph an eye E to be examined while observing it by infrared rays. A system control means 36 having detected an input in the observation switch 8 inserts visible-cut infrared transmission filter 17 into an optical path, while inserting a mobile mirror 31 into the optical path. As a result, the eye ground is lighted only by the infrared rays during the observation again and the photographer continues fluorescent photographing by operating a photographic switch 5, while observing an infrared image of the eye ground by a small display means 33. A person to be examined is lighted by a stationary light of visible light only during the period until fluorescence appears.  Thereafter, the photographing is carried on under the infrared observation to reduce pains caused by glaring. This allows the photographer to operate the observation switch 8 as required thereby enabling observation of a fluorescent eye-ground-image Er' with his naked eye without leaving the eye from a finder.

Title: Still image recording and reproducing device
Inventor: HIROSE KOICHI
IPC: H04N5/91
Filed: 1986-05-16
Abstract: PURPOSE:To always keep the continuity of the horizontal synchronizing signal period of a reproduced still image signal by cancelling the 0.5-H delay in the case that the switching of reproducing mode from the field still image reproducing mode to the frame still picture reproducing mode is executed within the 0.5-H-delayed field period. CONSTITUTION:A reproducing mode control circuit 24, in usual operation, controls so that a head switching switch16 is switched to a contact (a) side, and at the same time controls so that delay line switching switches 19 and 22 are aternately switched to contacts (c) and (d) at every one turning of a magnetic sheet 30, based on a TACH signal obtained from a rotation detection head 31. When a magnetic head 13 reproduces data from a frame still image signal are recorded, the reproducing mode control circuit 24 lets the switches 19 and 22 turn to the contact (d) side based on a discrimination output from a discrimination circuit 23 to release the 0.5-H delaying of a reproduced still image signal by 0.5H delay lines 18 and 21, and further lets the head switching switch 16 turn to a contact (b) side to switch the currently-used magnetic head from 13 to 14. As a result, the discontinuity at the field boundary that may occur to a horizontal synchronizing signal period and a color difference signal is prevented from occurring.
