Title: Electron gun for color picture tube
Inventor: IZUMIDA YUKIHIRO
IPC: H01J29/50
Filed: 1983-05-18
Abstract: PURPOSE:To enlarge the aperture of a main lens as well as to improve the assembling accuracy of an electron gun and make improvements in the focusing characteristic, by setting an electron beam passing hole of a main lens forming electrode down to each of specified deformed holes, while forming a special groove on the bottom surface of at least one side of electrode. CONSTITUTION:Two sets of elliptical thick platelike electrodes, which sets up three electron beam passing holes in-line form in a long diametrical direction, are made to be oppositely set up with the bottom side at regular intervals, and a main lens field forming electrode constituting a main lens electric field is installed in position between these opposite electrodes. Electron beam passing holes 50A-50C at both sides of an elliptical thick platelike electrode 50 of an electron gun for a color picture tube like this is set down to each of connected deformed holes setting the outer direction down to a semicircle while the inner direction to a semioval making the short diametrical direction of an oval thick plate a long diameter, respectively.

Title: Nitriding-preventing heat treatment for stainless steel wire
Inventor: KO NORIJI
IPC: C23F17/00
Filed: 1986-04-14
Abstract: PURPOSE:To prevent surface nitriding of stainless wires, by removing a wire- drawing lubricant adhering to stainless wires prior to heat treatment at the time of subjecting stainless wires to heat treatment such as wire drawing, etc., in an N2 gas-containing atmosphere. CONSTITUTION:Since a stainless steel for welding has remarkably high work hardenability, it is subjected to plural heat treatments and wire drawing workings at the time of wire drawing working so as to be worked into a stainless-steel welding wire. At this time, as a lubricant, a simple substance of stearate such as calcium stearate, sodium stearate, etc., or the one to which small amounts of MoS2, etc., are added is used. Prior to the heat treatment stage at the time of wire drawing working according to this process, the wire- drawing lubricant is removed by means of pickling or degreasing, so that exposure of high-activity steel-wire surface owing to the desorption of lubricant by decomposition in the course of heating for heat treatment can be prevented, and accordingly, the nitriding of stainless-steel welding wires due to N2 gas in the atmosphere can be prevented.

Title: Index head
Inventor: MATSUDA MASAJI
IPC: B23Q3/18
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To provide an index head capable of visually-reading an index angle directly. SOLUTION: An index 7 is set to the zero degree of a scale of an angle index member 4 mounted on an index head 1, and a vernier is set to the zero degree of a micro color 10. While an index handle 9 is being turned to an index angle to be determined, the angle of the unit of the degree of the index angle to be determined is confirmed and matched through the angle index member 4 and the index 7. When it reaches an aimed angle, the angle of the unit of minute is matched through the micro color 10 and the vernier. To determine the next angle, the above process is repeated.

IPC: H01L29/786
Filed: 1993-03-19
Abstract: PURPOSE:To prevent the failure due to the depletion type of an N-channel FET which is not intended and the failure that the threshold voltage of a P- channel FET shifts largely to the negative side, by performing heat treatment for a specific time or longer in an oxidizing atmosphere after a gate insulating is formed. CONSTITUTION:After an Si thin film 2 is formed on a substrate 1, an I-type region 2a and an N-type region 2b are formed by the selective doping of N-type impurities. The Si thin film 2 is patterned in a specific form and turned into an island. A gate insulating film 6 is formed at 600 deg.C or lower. After contact holes C1, C2 are formed, a gate electrode 7 is formed, and a source electrode 8 and a drain electrode 9 which are in contact with a source region 4 and a drain region 5 are formed. While the substrate is heated according to the need, annealing is performed for 10 minutes or longer in an oxygen atmosphere, thereby neutralizing positive charges in the gate insulating film 6. Hence the quality of an N-channel TFT can be improved.

Filed: 1983-05-19
Abstract: PURPOSE:To detect optically the moving speed of a moving body with high accuracy under a non-contacted condition, by detecting correlatively the moving condition of a speckle pattern formed by receiving reflected lights from the moving body. CONSTITUTION:When a moving body 10 is irradiated with a spotlight from a laser light source 12, a speckle pattern which moves in accordance with the moving speed of the moving body is formed and the pattern light is received by a photodetector 11 which is composed of photoelectric element arrays and controlled by a shift pulse SP from a divider 15. Then the correlative value of the speckle pattern is calculated by a correlator 23 based on similarity obtained by shifting successively the sample value of the previous and current outputs of the detector 11 one by one through memories 17 and 18 which writing and reading mode are switched at every shift pulse SP, etc. Successive correlative values are processed by a buffer 24 and comparator 25 and the moving quantity of the speckle pattern between pulses SP corresponding to the moving speed is calculated by means of an up-down counter 28 which performs up-counting at every comparison until the correlative value becomes minimum and the difference in the correlative value is inverted. In this way, the moving speed of the moving body 10 is measured with high accuracy under a non-contacted condition.

IPC: H01J61/10
Filed: 1994-03-18
Abstract: PURPOSE:To reduce the influence of an electric field generated near electrodes and a magnetic field to delay the blackening, and prolong the lifetime by stretching a band made of magnetic material over the glass surface of a fluorescent tube at electrode positions in both ends thereof or changing the structure of the electrodes. CONSTITUTION:A band made of the C-shape magnetic material 1 is stretched around the periphery of coiled electrode filaments 6 of both ends of a fluorescent tube 2 over a glass tube. A V-type, U-type and O-type band can be used in place of the C-type. A core of the filament 6 is fitted in the coaxial direction with the fluorescent tube 2, or the filament 6 is folded into two to form a bifilar winding. Furthermore, shielding plates 7 made of metal plate are fitted to both ends of the filament 6. Stretching of a C-type band is desirable to be used with other method. Exposure of one part of the fluorescent coating with electron or gas molecular by the generation of an electric field due to the discharging phenomenon and the generation of a magnetic field due to the filament 6 is thereby reduced to delay the blackening.
