Title: Electron gun for cathode-ray tube
Inventor: JITSUKATA HIROSHI
IPC: H01J29/48
Filed: 1981-05-08
Abstract: PURPOSE:To obtain beam spots with a small diameter by making the beam passing hole of a control electrode to have a rectangular shape, and making the opened sections of electrodes forming a main electrostatic lens to have rectangular shapes the directions of the long sides of which correspond to the direction of the long side of the rectangular beam-passing hole. CONSTITUTION:A control electrode 2 of an electron gun is provided with an electron-beam passing hole 11 having an almost rectangular shape. The opened sections of a focusing electrode 4a and an accelerating electrode 5a, which work as a main focusing lens system, have rectangular shapes the directions of the long sides of which correspond to the direction of the long side of the hole 11. As a result, the spherical aberration of the long side of the electron gun doesn't become larger than that of the short side of the gun, and small beam spots with an almost circular shape can be obtained on a fluorescent screen.

Title: Semiconductor device
Inventor: SAKURAI JIYUNJI
IPC: H01L29/10
Filed: 1978-06-07
Abstract: PURPOSE:To establish MOSFET of high dielectric strength, by providing the low concentration layer from the substrate in the semiconductor substrate under the opening of insulation film. CONSTITUTION:The SiO2 film 13 of the P<+> substrate 10 is opened and the P layer 17 is formed with N type ion injection. The concentration and depth of the layer 17 can be determined by referencing the depth of the next N<+> diffusion. Further, the P<-> epitaxial layer 12, gate oxide film 13, and polycrystal Si gate electrode 14 are formed selectively. Succeedingly, the electrode 14 is made conductive with the N<+> diffusion to form the N<+> layers 15 and 16. In this case, even if the N<+> layers 15 and 16 are extended to the P<+> substrate side, the junction is formed with the N<+> layer and the P layer 17. Since the layer 17 is selected with the concentration to obtain desired greater dielectric strength, the increase in the junction capacitance and the lowering in the source and drain dielectric strength as conventional devices can not be taken place.

Title: Aqueous colloid dispersion liquid for fumed silica
Inventor: DENISU JII MIRAA
IPC: C04B14/06
Filed: 1990-03-20
Abstract: PURPOSE: To improve stability by dispersing specific amts. of fumed SiO 2  an acid and a stabilizer into water.  
     CONSTITUTION: The water is charged into a high shearing mixer. The acid selected from hydrochloric acid, sulfuric acid or acetic acid, etc., is then added thereto at about 0.0025 to 0.50 wt.% on the basis of the weight of the fumed SiO 2  to be added. While the mixer is kept operating, the fumed SiO 2 , having a surface area below about 75m 2 /g is added thereto in the amt. to attain a concn. of about 60 wt.%, by which the first dispersion is formed. The additional water is thereafter added thereto to dilute the dispersion and to prepare the aq. colloidal dispersion of the concn. of at least about 40 wt.%, following which the stabilizer like alkali, such as NH 4 OH, or amine, such as triethyl amine, is added to the dispersion and the pH of the final dispersion is adjusted to about 7 to 12. The aq. colloidal dispersion of the fumed SiO 2  is thus obtd.

Title: Production of diaphragm for acoustic apparatus
Inventor: HIROSE MINETAROU
IPC: H04R7/02
Filed: 1978-06-07
Abstract: PURPOSE:To enable the diaphragm having a required thickness to be inexpensively produced in a short time by rapidly spreading the diaphragm raw material having been heated and melted on the specific substrate then cooling and solidifying the same. CONSTITUTION:Raw material such as B is inserted in pipe-form refractories 4 and is placed on a support base 13 together with a heating furnace 3. A flange part 8 is strongly pushed to the furnace 3 to fix the furnace 3 and secure airtightness so that high pressure gas 10 is supplied only into the refractories 4. A hermetic vessel 12 is put on a base 14 and the inside of the vessel 12 is evacuated. After the raw material 1 is heated and melted by the W heater 5 of the furnace 3 provided with heat-insulating refractories 6, a valve 9 is rapidly opened to allow the gas 10 to be blown into the refractories 4 through the pipe 7. The molten raw material 1 is injected from the portion 4a of a smaller sectional area onto the substrate 2 which is being rotated at a high speed about the center of the substrate 2 as its rotating center by a rotating mechanism 11. The material is then spread thinly, cooled and solidified, whereby the thin plate to become the diaphfragm is formed.

Title: Manufacture of semiconductor device
Inventor: NEMOTO TAKENAO
IPC: H01L21/3213
Filed: 1993-03-26
Abstract: PURPOSE:To improve the electromigration resistance of metallic wiring formed of Cu-added Al. CONSTITUTION:After forming wiring on a metallic thin film, a semiconductor is subjected to aging treatment at a temperature between 100 deg.C and 250 deg.C. As a result, the electromigration resistance of the metallic thin film can be improved without increasing the Cu content of the thin film, since a sufficiently large amount of an Al-Cu alloy is deposited in the thin film. It is desirable to perform the above-mentioned aging treatment to the semiconductor device when the device is abruptly heated to about 400 deg.C and abruptly cooled from the temperature at the time of packaging the device during the course of the manufacturing process of the device, because it is considered that the Al-Cu alloy deposited on boundaries of Al grains is taken into crystal grains when the semiconductor device is abruptly heated and cooled.
