Title: Electronic equipment
IPC: G06F1/16
Filed: 1992-03-19
Abstract: PURPOSE:To miniaturize a device by performing an opening/closing operation in two stages on a display device centering different rotary shafts in the middle state from a closed position to a position confronting with an operator. CONSTITUTION:An opening/closing mechanism 3 which connects an electronic equipment main body 1 to the display device 2 is provided with a mechanism main body part and a projection, and the electronic equipment main body 1 and the display device 2 are provided with a sliding part 7 and a sliding part 8, respectively. When the display device 2 is opened/closed, the opening/closing operation in two stages of the display device 2 can be surely and smoothly performed by suppressing the turning of the mechanism main body part by the projection, and controlling the turning of the display device 2 by the sliding parts 7, 8 according to their shape. Thereby, it is possible to miniaturize the device without taking excessive space for the opening/closing mechanism 3.

Title: Camera having inspection function and film cartridge
Inventor: MURAKAMI KOICHIRO
IPC: G03B17/00
Filed: 1994-03-31
Abstract: PURPOSE:To make the operation in camera production process easier and simpler and to enhance the functions of a camera to higher performance and higher quality by recording an information indicating a film cartridge for inspecting the functions of the camera on a specific film cartridge. CONSTITUTION:Tracks Ffs of reference positions are parts where magnetic information are recorded in track positions which are references. Ff1 to Ff8 are the parts where the information are recorded by shifting the track positions stepwise in the width direction of the film relative to the reference positions with respect to the magnetic recording parts Ffs having the magnetic information recorded at 8 points of the reference positions of a short length. The tracks Ff1 to Ff8 for inspection are reproduced by a magnetic head in such a manner, thereby, the magnetic reproduced output of the recording parts Ffs is maximized if the magnetic head exists in a correct position. The degree at which the magnetic head tracking position deviates is known if the max. reproduced output exists in the magnetic recording parts of Ff1 to Ff8. As a result, the magnetic head is easily mountable at the optimum position.

Title: Removing method for gas and inclusion from molten steel
Inventor: TAKEMURA YOUZOU
IPC: C21C7/072
Filed: 1981-04-28
Abstract: PURPOSE:To remove gases and inclusions from molten steel simultaneously in the stage of transferring the molten steel from one vessel to another vessel by blowing an inert gas and setting the amt. of said gas and the fall of the molten steel at specific values or above. CONSTITUTION:In the stage of flowing and moving molten steel from one vessel into another vessel, the molten steel is flowed and moved while an inert gas of 0.01-1.0Nm<2>t-steel is blown from near the steel outflow hole of the one vessel. In this case, the fall of the molten steel to the other vessel is assured at <=2.0m. Then, the foam diameter of the inert gas is reduced considerably, and the degassing and inclusion removing effects of the molten steel are shown. Here, if the fall of the molten steel is <=2m, the size of the inert gas foam increases sharply, and when the fall is large, the blowing amt. of the inert gas can be decreased but it is required to be the lower limit or above, and the upper limit or above is infeasible in practice. If powder of CaO, CaCO3, etc. is blown together with the inert gas, the inclusion removal effect is much improved.

Title: Liquid crystal display device and its production
Inventor: KUBOTA TAKESHI
IPC: H01L29/78
Filed: 1994-03-31
Abstract: PURPOSE:To allow an image displaying performance not to be deteriorated by making the restoration of a short-circuited fault possible when dust. etc., are intermixed in between electrodes of a signal holding capacitor and a point defect due to the short-circuited fault is generated and also allowing the capacitance of the signal holding capacitor not to be changed in the signal holding capacitor of a liquid crystal display device. CONSTITUTION:In this device, electrodes of the signal holding capacitor are made to be plural electrodes (a first to a third electrodes 8, 10, 16) of more than three electrodes and are made to be in a state in which adjacent electrodes are electrically connected. When a short-circuit is generated in between electrodes of the signal holding capacitor, the electrically connected connection part in between electrodes in between whose electrodes the short-circuit is not generated is cut with a laser, etc., to restore the capacitor, then a new signal holding capacitor is formed. Since the capacitance of the signal holding capacitor is not changed largely by this restoration, the point defect of the image is eliminated without deteriorating the image displaying performance.

Title: Recovering method for thallium from lead electrolytic solution
Inventor: OODO SHIYUUICHI
IPC: C25C1/22
Filed: 1980-05-15
Abstract: PURPOSE: To prevent the aging of a Pb electrolytic soln. contg. Tl due to the decomposition of additives in the soln. by using a diaphragm type anode when Tl is recovered from the soln. by electrolysis.  
     CONSTITUTION: An electrolytic soln. used in the electrolytic refining of Pb contains several W20g/l Tl. This soln. is poured into an electrolytic cell 1 and circulated through the inside and outside of the cell with a pump P. An anode 5 is put into a diaphragm 6 made of wood, synthetic resin, ceramic or the like, and the diaphragm 6 is filled with a sulfuric acid soln. having about 200g/l concn. as an anolyte 7 to produce an anode structure 3. This structure 3 is immersed in the electrolytic soln. 9, and by applying a DC voltage between the structure 3 and a cathode 2, Tl is deposited on the cathode 2 and recovered. Since the anode 5 hangs in the diaphragm 6, it does not directly contact with the soln. 9, and the soln. 9 is not aged by the decomposition of glue, sodium lignate, etc. contained in the soln. Thus, Tl deposit on the cathode 2 has high purity such as ≥99.99%.

Title: Plane light source
Inventor: SANO TOSHIHIKO
IPC: G02F1/13357
Filed: 1986-03-24
Abstract: PURPOSE:To uniform the brightness distribution on the surface of a light guide by using an aperture lamp as a fluorescent lamp and setting its aperture opposite a reflecting plate side. CONSTITUTION:When the aperture fluorescent lamp 4 is set having its aperture part 3 opposite the side of a reflecting plate 2, high-brightness light 5 from the aperture part is guided to both end parts of a diffusing plate 1 and low- brightness light 6 from the part except the aperture part is guided to the center part of the diffusing plate 1 respectively. Therefore, the center part of the diffusing plate 1 respectively. Therefore, the center part of a normal fluorescent lamp where the brightness of the brightness distribution 7 is high decreases in brightness and both end parts where the brightness is low increases; and those two variations uniform the brightness distribution under set conditions in this case. Thus, one aperture fluorescent lamp satisfies the set conditions, so a plane light source is obtained on the top surface of the diffusing plate and the efficiency is not spoiled.

Title: Semiconductor device
Inventor: FUKUI TAKAMICHI
IPC: H01L21/8242
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To avoid the breakdown of a gate oxide film, when a stress is imposed on a nitride film due to heat history, etc., by setting up the thickness of an insulating film underneath to be a specific times that the thickness of a nitride film. SOLUTION: A nitride film 8 is formed on a first underneath insulating film 7 by an LP-CVD process further to form the second underneath insulating film 9 on the nitride film 8 by a CVD process. Later, the surface of the second underneath insulating film 9 is flattened by etchback process using SOG or CMP. At this time, the breakdown life of a gate oxide film is made equivalent to that, when the nitride film 8 has not yet been formed by increasing the distance between a gate electrode 3 and the nitride film 8 about 20 times or more. Furthermore, the total implanted charge amount can be increased in proportion to the increased distance between the gate electrode 3 and the nitride film 8. Through these procedures, the stress imposed on the gate oxide film by the underneath insulating films can be relieved, thereby enabling the breakdown life of the gate oxide film to be lengthened.
