Inventor: DATE YOSHITO
IPC: G09G3/36
Filed: 1990-01-31
Abstract: PURPOSE:To obtain the liquid crystal display device which does not cause its liquid crystal display panel to deteriorate even if the display control signal of a computer is ceased by providing a counter which counts a dot clock outputted from a display control system and a decision means which judges whether or not a horizontal synchronizing signal is outputted from a display control system. CONSTITUTION:This liquid crystal display device consists of the counter 15 which counts the dot clock from the CRT display control system of the computer and the circuit 16 which judges whether or not the computer outputs the horizontal synchronizing signal. Namely, the device is provided with the clock counter 15 which generates a dummy signal even if the signal of the synchronizing signal line from the CRT display control system 1 is ceased and the selector which switches the original synchronizing signal. Consequently, the liquid crystal display device which never causes the liquid crystal display panel 2 to deteriorate even if the horizontal synchronizing signal from the CRT display control system 1 is ceased is obtained.

Title: Multicolor fluorescent character display tube
Inventor: KIKUTA SHIGEKI
IPC: H01J31/15
Filed: 1985-02-12
Abstract: PURPOSE:To produce a multicolor fluorescent display tube which emits several colors according to the operation condition by forming a phosphor by performing low resistance treatment on a zinc-sulfide-system or zinc-cadmium-sulfide-system phosphor activated by manganese and a metal other than manganese. CONSTITUTION:Either a zinc-sulfide-system phosphor such as ZnS or a zinc- cadmium-sulfide-system phosphor is activated by manganese and a metal other than manganese such as Ag and the resistance of the phosphor is reduced by a compound such as indium oxide to prepare a phosphor which emits light when low-velocity electron rays bump against it. After that, this phosphor is applied to an anode by printing, thereby making a fluorescent character display tube. In this fluorescent display tube, either the voltage or the current density of the anode is varied to produce two bands of luminous spectrum. The luminous color of the fluorescent character display tube can be varied by varying excitation condition. Consequently, it is possible to easily produce a multicolor fluorescent character display tube having stable luminous color.

Title: Heat exhausting structure for electronic equipment
Inventor: ITO TOSHIAKI
IPC: G06F1/20
Filed: 1989-02-03
Abstract: PURPOSE:To prevent exhaust of heating in the equipment from giving an uncomfortable sense to an operator by providing a space part on a top board part of a counter, using the space part as an exhaust use duct, and also, connecting the duct to the outside of a room. CONSTITUTION:Hot air exhausted forcibly from an exhaust use fan provided on an exhaust hole 5-1 of an electronic equipment installed under a knee of an operator 9 is led into a space part 8-1 of a top board 8 from the inside of a partition plate 7 of a counter, and exhausted to the outside of a room by connecting one end of the top board part 8 to the outside of a room. Accordingly, hot air brought to exhaust heat from the electronic equipment goes into the partition plate 7 of the counter, and also, goes into the top board hollow part 8-1 since the inside of the partition plate 7 is connected to the inside of the top board 8, and exhausted from an end part of the top board 8. In such a way, it does not occur that exhaust from the electronic equipment installed under the knee of the operator 9 hits against feet of the operator 9, and also, since exhaust heat is exhausted to the outside of a room, an uncomfortable sensing is not caused to not only the operator 9 but a customer.

Title: Magneto-optical recording medium and magnetooptical recording and reproducing method using the same and magneto-optical recording and reproducing device
Inventor: MIYAMOTO JIICHI
IPC: G11B11/10
Filed: 1993-02-12
Abstract: PURPOSE:To obtain high S/N and to lessen the generation of crosstalks at the time of making tracks narrower in pitch by forcing a recording layer having >=2 axes of easy magnetization in a direction parallel with a substrate surface. CONSTITUTION:The recording medium having a recording film 1 laminated with Gd22Co88 by a sputtering method on a transparent substrate 2 having grooves 7 formed by a 2P method, etc., is subjected to recording. Spots are formed by condensing laser beams 3 with lenses 9 at this time. The temp. in the spot parts rises up to the Curie temp. of the film 1 and makes coercive force small when the beams 3 are strong. The spot parts are thus magnetized in the recording magnetic field 11 direction with a recording magnetism impressing means 10. The magnetization change does not arise when the beams are weak and, therefore, the recording marks are formed only when the beams are strong. Unrecording parts 6 where the magnetization direction 8 is reversed from the recording magnetic field are formed before recording and, therefore, the magnetic field 11 is magnetized in the reverse direction by irradiating the tracks with the strong beams 3 while the magnetic field 11 is reversed. As a result, the recording information is stabilized and noises are decreased. The adjacent track information is not picked up and the crosstalks are decreased even at the time of reproducing.

Title: Method for preventing corrosion and contamination of shell plate
Inventor: UEDA KENJI
IPC: B63B59/04
Filed: 1984-02-10
Abstract: PURPOSE:To prevent semipermanently corrosion and contamination of the shell plate by covering said plate with a copper-base metallic material and maintaining the protective current value only during sailing at an optimum value based on specific potential thereby effecting electrolytic protection. CONSTITUTION:The submerged part of a shell plate 1 is covered by a copper or copper alloy material 2. A power source 3 in the ship and an electrode 4 which is hoisted up and down by a hoisting device 6 are connected by a conductor 5 and the material 2 and the power source 3 as well as one end of a control device 8 are connected by a conductor 7. The device 8 detects the sailing and stop of the ship, commands the device 6 and receives the signal from a reference electrode 9 provided in part of the plate 1. The power source 3 turns off and the device 6 lifts the electrode 4 from the sea when the ship calls at a port. Then the material 2 elutes to generate an effect of preventing contamination. When the ship leaves the port, the device 6 casts the electrode 4 into the sea by the command from the device 8 and the power source 3 is turned on by the signal passing through the wire 12 of the device 8, then protective current 13 flows from the electrode 4 into the material 2, thereby decreasing the elution of the copper. The optimum current value is maintained in this stage by detecting the potential of the material 2 by the electrode 9 and controlling the power source 3 by the device 8 based on said value.
