Title: Direct positive image formation
Inventor: TOSAKA YASUO
IPC: G03C5/50
Filed: 1981-10-06
Abstract: PURPOSE:To facilitate control of each color gradation of a positive image, by changing intensity and/or exposure quantity of whole surface exposure in processing of light fogging after imagewise exposure of a photosensitive material having plural internal latent image type silver halide emulsion layers. CONSTITUTION:A silver halide color photographic material having at least 2 internal latent image type silver halide emulsion layers different from each other in each sensitive wavelength region, and each not fogged in advance is imagewise exposed, and subjected to whole surface exposure before or in a developing process to form a direct positive image. At that time, gradation of each color image is controlled by changing intensity and/or exposure quantity of radiation in the photographically effective wavelength region of the whole surface exposure. For example, when exposure quantity is maintained constant, the stronger the intensity, the lower contrast positive image is obtained, and when intensity is held constant, the more exposure quantity, the lower contrast image is obtained, thus permitting a desired gradation positive image to be obtained.

Title: Cipher control method of communication terminal
Inventor: ITAKURA TERUO
IPC: H04L9/08
Filed: 1983-08-31
Abstract: PURPOSE:To prevent the leak of a cipher by updating the cipher at every communication call for every communication destination. CONSTITUTION:When a communication is terminated, a cipher number generating circuit 26 of a terminal 2 is started, and a cipher is generated by, for example, rangom numbers and is sent to a terminal number cipher storage circuit 24. This circuit 24 updates contents of a memory corresponding to a destination terminal 1, with which a terminal 2 comunicates just before the communication is terminated, to said generated cipher. This new cipher is sent to the destination terminal 1 through a cipher transmitting circuit 27. Consequently, the new cipher is used for the next communication between terminals 1 and 2. Thus, even if the cipher used in the preceding communication is deciphered, communication contents are not leaked because another new cipher is used for communication.

Title: Water television camera
Inventor: SASAGAWA SHINYA
IPC: H04N5/225
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To turn on lights only when a television camera is under water by fitting a float switch for light to the television camera and automatically controlling the light by the up/down movements of a float. SOLUTION: When the television camera 1 is under water, the float rises, the float switch 3 is turned on and the lights 21 and 22 are turned on. When the television camera rises from beneath water by the change of a water level, maintenance and cleaning, the float 4 goes down, the float switch 3 is turned off and the lights 21 and 22 are put out. The fitting position of the float switch 3 is slightly higher than the glass faces of the lights 21 and 22 by considering the glass damage prevention of the lights 21 and 22. Even if the television camera 1 rises/descends by the change of the water level, maintenance and cleaning, the operation of 'OFF' or 'ON' of the lights 21 and 22 is prevented from being forgotten. Then, a system can be operated without causing the secondary damage of glass in the lights 21 and 22.

Inventor: TAKAGI TOSHIYUKI
IPC: B41J13/00
Filed: 1987-06-26
Abstract: PURPOSE:To prevent paper from being passed through a printing part before formation of an image on a photosensitive drum even when it takes time to expand data into dot patterns, by applying paper feed control individually to a paper-feeding part between a paper-supplying part and the printing part and a paper-feeding part between a sub-stacker and the printing part, after expansion of the data into the dot patterns. CONSTITUTION:A perfect printer comprises a paper-supplying part 11, a printing part 14, a sub-stacker 16 for maintaining paper printed on one side thereof, a first paper feeding-out part 9 for feeding the paper from the paper-supplying part 11 to the printing part 14, and a second paper feeding-out part 18 for feeding the paper printed on one side thereof from the sub-stacker 16 to the printing part, with the unprinted side as a printing surface. The perfect printer is operated under such control that printing data is expanded into dot patterns, printing is conducted on one side of the paper, the paper thus printed on one side thereof are maintained in the sub-stacker 16, and then printing is conducted on the remaining side of the paper, thereby completing perfect printing. Particularly, paper feed control over the first paper feeding-out part 19 and paper feed control over the second paper feeding-out part 18 are individually performed after completion of expansion of the printing data, to be printed on each side of the paper, into the dot patterns.

Title: Paper lift-up stopper
Inventor: MORIMOTO KIYOSHI
IPC: B65H3/00
Filed: 1985-05-31
Abstract: PURPOSE:To stop a motor in a state that proper pressure is added to a paper feed roller, by installing an operating member which turns a pass of light on or off at each zone. CONSTITUTION:At the point that a rear edge 823 of a light passing window 822 comes to near a slit 812, an operating member shifts from a first lift-up zone theta1 to an inertial lift-up zone theta2, therefore light passing comes on. And, the slit 812 passes through the zone theta2, and enters a second lift-up zone theta3 by little inertia force. In consequence, the light passing comes off whereby a reversible motor is redriven. And, when a front edge of the operating member 820 runs past the slit 812, a power source of the reversible motor is turned off. Here, since the zone theta2 is set so as to become a shorter built-up period than a build-up period T of the zone theta1, inertia of the reversible motor in this is small, whereby the rotation stop at once. That is to say, an upward velocity of copying paper is little whereby this copying paper comes into a state of being contacted with a first paper feed roller with proper pressure.
