Abstract: PURPOSE:To make it possible to form a visible image by displaying a black and white image on a liquid crystal panel in accordance with an image signal and heating a photosensitive recording medium after the exposure of the displayed image on the photosensitive recording medium. CONSTITUTION:If a command for image printing is entered by manipulating a controlled display part 68, a control circuit 50 selects between filters which permit a lambda1 wavelength component to pass by controlling a filter drive mechanism 56, and then introduces the selected filter into an optical path 34 from a light source 12. In addition, the control circuit 50 instructs a frame memory unit 62 to read blue component data. Subsequently, the blue component data is read sequentially in order of raster scanning of the blue component data and then is supplied to a liquid crystal panel 18 by an output of the drive circuit 44, resulting in a visualization of a black and white image. Synchronized to this visualization process, the control circuit 50 enables the light source 12 to emit a light, so that a blue component image is recorded as a latent image in the lambda1 photosensitive layer 120 of a photosensitive sheet 78. Similarly, the remaining color component images are recorded in a lambda2 photosensitive layer 116 and a lambda3 photosensitive layer 112. Next, the control circuit 50 transports the exposed photosensitive sheet 78 to a thermal development part 20 and controls a derive circuit 52 for the thermal development part to heat the sheet 78.

Title: Plasma display
Inventor: HOSONO MASAHISA
IPC: G09G3/28
Filed: 1991-05-09
Abstract: PURPOSE:To detect a resistance on a surface when a panel is broken so as to inhibit an output of a high voltage by grounding a part of the end portion of a transparent film to a ground, and connecting a part of the other end portion to a logic power source via a resistance. CONSTITUTION:On a display surface of a panel 1, there is provided a conductive transparent film, on one side of the left end of which is grounded by the use of metal electrodes 2. A part of the end portion of the transparent film is connected to a logic power source via a resistance R2. There are further provided a surface resistance RP of the transparent film and a resistance R3 having a resistance value slightly higher than the resistance RP. Accordingly, since a differential input voltage of a comparator 3 becomes a value relating to a voltage VCC of the logic power source, it is normally plus so that an output is also plus, thus leading to operation of a high voltage power source 4. When the panel 1 is broken, the resistance RP is increased. As a result, the differential input voltage of the comparator 3 becomes minus. Consequently, the output of the comparator 3 comes into a low level, thus stopping the output of the high voltage power source 4.

Title: Electrically rewritable nonvolatile memory
Inventor: HAMAMOTO KATSUYA
IPC: H01L21/8247
Filed: 1993-04-28
Abstract: PURPOSE:To prevent the occurrence of erroneous erasure, erroneous writing, and erroneous reading by making a driver to select and drive all word lines at a fixed voltage during the period of a reset signal outputted from a reset circuit when the power supply is turned on and a discharge circuit to discharge electricity from a control gate and bit lines. CONSTITUTION:When the power supply is turned on, a reset circuit 2 outputs a reset signal 201 for a fixed period of time (several mus) and a bias circuit 3 outputs a fixed voltage (2V) 301 upon receiving the signal 201. When the signal 201 is inputted, a driver 4 selects and drives all word lines by outputting a voltage which is equal to the voltage 301 to word lines 101 and 102. As a result, four memory cells 1 are turned on and a discharge circuit 5 starts discharging operations to discharge electricity from control lines 111 and 112 and bit lines 121 and 122. When the circuit 5 starts the discharging operations, the cells 1 are short-circuited with each other, but, since all word lines are not selected and driven with a power supply voltage at a logically high level, but with the voltage of 2V which is lower than the lowest programmable voltage, the occurrence of erroneous erasure, erroneous writing, and erroneous reading is prevented.
