Title: Formation of organic thin film using radical and organic thin film forming device
Inventor: NAGASHIMA NAOKI
IPC: C23C14/12
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To provide a technique for forming an org. thin film on the activated surface of a substrate without receiving any damages. SOLUTION: A substrate is arranged in a vacuum vessel 12 before an org. thin film is formed on the substrate 11, the vessel is evacuated, the substrate 11 surface is irradiated with a radical by a radical gun 5, then the substrate is sent to an evacuated vacuum vessel 32, and the org. thin film is formed on the activated surface. Since the surface is treated with the radical gun 5, a transparent conductive film is hardly damaged, and even a substrate of resin is treated because a temp. rise is slight. The org. film is formed without being exposed to the atmosphere after the transparent conductive film surface is activated, hence the adhesion of the transparent conductive film to the org. thin film is improved, and an EL element good in characteristic is obtained.

Abstract: PROBLEM TO BE SOLVED: To remarkably relax the problems of tired eyes and ached eyes of a driver caused by excessive brightness by providing a means for measuring the brightness in a room having a monitoring device and a means for controlling the brightness of a back light in response to the measured brightness. SOLUTION: A photo sensor 27 changes the level of an output current in response to light intensity and the current is transformed to a voltage by a signal processing circuit 26 and the voltage signal is transformed to a digital signal of 10 bits, for example, by an A/D converter. On the other hand, the brightness of a liquid crystal panel 21 is changed by controlling the inverter 23 of a back light and changing the brightness of a back light 25. A CPU 10 reads the digital signal of the brightness in a driver's room from the A/D converter and compares it with a threshold value previously memorized in a ROM 11 to determine a brightness level in the stepwise adjustment of a level 1 for a fine weather during a day (maximum brightness), a level 2 for a cloud weather during a day (intermediate brightness), and a level 3 for night (minimum brightness).

Inventor: LEE SEUNG HEE
IPC: G02F1/1368
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To improve transmissivity of light, a numerical aperture and a response speed by alternately arranging a counter electrode and a pixel electrode without a gap and forming the counter electrode and the pixel electrode from transparent substance. SOLUTION: The counter electrodes 2b-2f and the pixel electrodes 5a-5d in a liquid crystal are arranged without a gap each other. Then, since the space where an electric field is applied is narrowed, the response speed of a liquid crystal display device is improved. Further, since the counter electrodes 2b-2f and the pixel electrodes 5a-5d consist of the transparent substance, the transmissivity and the numerical aperture are improved. At this time, since the counter electrodes 2b-2f and the pixel electrodes 5a-5d consist of the transparent substrate, the width of the counter electrodes 2b-2f and the pixel electrodes 5a-5d is formed narrowly for driving the liquid crystal existing on the upper part of the counter electrodes 2b-2f, the pixel electrodes 5a-5d. Thus, the transmissivity of the liquid crystal display device is improved further.

Filed: 1991-12-03
Abstract: PURPOSE:To unnecessitate the reconstruction of the program library by estimating the image subdividing the storage area and deciding the recycle of the corresponding section for each update of a program. CONSTITUTION:In the storage medium storing the program library performing the registration of a new program or the update of the stored program, the image data multi-dividing the program storage area for each step number size (mesh) is prepared (for example, one section is taken as 100 steps to decide the main frame such as 0001, 0100 to nnnn) in updating or newly registerring programs, then at least one of the divided unit areas is allocated to the program. For each update of the program, the recycle of the unit area corresponding to the program is decided based on the utilization rate. Thus, the recycle of the storage area which has been treated as a dead area is enabled, unnecessitating the reconstruction of the program library.

Title: Power supply
Inventor: KOSAKA MITSUAKI
IPC: H02M7/48
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To accurately detect whether a load is normal or abnormal, even if the output voltage to the load is DC or DC-superposed by making a difference in induced voltages between both U cores a specified value or below, when the load is normal and making it a larger value than that when the load is normal, when the load is abnormal. SOLUTION: When the output voltage to a load is DC-superposed, leakage magnetic flux is different at the A side (negative side) and B side (positive side) of a secondary winding. Therefore, low resistors R1, R2 are set to such values that the voltages V1 , V2 at points A, B are nearly the same at normal operation. With the appropriate setting of the values of the low resistors R1, R2, current is not made to flow into a detection resistor R5, because V1 becomes equal to V2 and R3 becomes equal to R4 in the case that each neon tube is correctly connected, and therefore the neon tube emits light. When one of the neon tubes is broken or the like, however, the voltages induced in both the U cores are greatly different, and a specified voltage Vdet appears in a second high resistor R5. By this method, it can be told clearly distinguished whether a load is normal or abnormal.

Title: Display method for sequence control
Inventor: KAWAKAMI TAKAYUKI
IPC: G05B19/05
Filed: 1989-12-28
Abstract: PURPOSE:To make a high speed data transfer means unnecessary by transferring display data from a sequence controller to a display device when the display device is connected to the sequence controller and picture-displaying the content of display data concerned by means of a control code from the sequence controller. CONSTITUTION:Display data is stored in the display data storage part 2c of the sequence controller 2A. When the display device 3A having a display data storage part 2c is connected to the sequence controller 2A, display data is transferred from the display data storage part 2c of the sequence controller 2A to the display data storage part 3c of the display device 3A so as to store it. After display data is transferred, the sequence controller 2A outputs the control code showing a display content to the display device 3A, which extracts display data equivalent to the control code from the display data storage part 3c and displays a picture. Thus, a private line for improving the transfer speed of display data can be made unnecessary.

Abstract: PROBLEM TO BE SOLVED: To smoothly move a guide member with a simple constitution and effectively carry out restriction to movement of an endless belt in the direction perpendicular to the rotation without shortening its service life. SOLUTION: In this image forming device, a guide 332 is provided in a driven shaft 331 of a driven roll 33 and energizing springs 333 are installed in between a side board 335 to which the driven shaft 331 is attached through a bearing 334 and the guide 332.
