Title: Device for cooling main electric motor of rolling stock
Inventor: KANDA MASAHIKO
IPC: B61C17/00
Filed: 1990-11-28
Abstract: PURPOSE:To surely prevent drops of water from entering into a main electric motor in a device wherein fresh air is taken in by a blower and allowed to flow into the main electric motor via an intake duct by sticking water absorbing material on the inner surface of the duct, and providing heating elements in close contact with the outer surface of the duct. CONSTITUTION:A duct 3 is connected at one end to a main electric motor 1 via a flexible air duct 2 and connected at the other end to a blower 4. The duct 3 extends downward from the blower 4 and is immediately curved horizontally and extends horizontally and is then curved downward and connected to the flexible air duct 2. Water absorbing material 5 is stuck to the horizontal portion and the curved exit portion of the duct 3 and heating elements (positive characteristic thermistors) 7 are stuck to the horizontal portion of the duct and the outside of the curved exit portion via a heat conducting plate 6. If some snow is mixed in cooling wind supplied from the outside of a train by the blower 4, the snow is melted by the heat conducting plate 6 heated by the heating elements 7 and is absorbed by the water absorbing material 5. The water absorbed is evaporated by heating so that the water absorbing property of the water absorbing material 5 is maintained.

IPC: G02F1/133
Filed: 1987-12-23
Abstract: PURPOSE:To obtain an effective aperture rate of 100% and to improve picture quality with high contrast and high brightness by forming grooves on the picture element electrode formation side of a glass plate except where picture element electrodes are to be formed. CONSTITUTION:The grooves 11 are formed in the lower glass substrate 1 except where the picture element electrodes 5 are formed. Reflecting films 12, e.g. Al film are formed on the glass substrate 1 where the grooves 11 are formed and flattened by lapping, etc. Scanning electrodes, thin film transistors (TR) 4, signal electrodes 3, and the picture element electrodes 5 are formed on the flattened glass substrate 1 where the reflecting films 12 are charged across, for example, SiO2 insulating layers. Light incident on the groove where the reflecting film 12 is formed is reflected and gathered in the area of the picture element electrode 5. Namely, a wiring part converges even light which enters the thin film TR part and not utilized before on the picture element electrode area. Light incident to effective screen area is therefore all incident on the picture element electrode area. Consequently, the effective aperture rate is 100%, the contrast and brightness are improved, and the picture quality becomes excellent.

Title: Luminescence device
Inventor: RIKIHISA HIROAKI
IPC: H01J61/04
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To shorten the distance from an electron generation point to a luminescence point and to allow luminescence on a face by providing a medium generating electrons when receiving the light of a photoelectric material, a medium generating light when receiving the electrons of a fluorescent material, and a means feeding energy to electrons. SOLUTION: A reflecting face 40 of light and the face of a fluorescent material 30 are overlappingly arranged, and a voltage is applied between the fluorescent material 30 and a photoelectric material 20. When light hits the photoelectric material 20, for example, electrons are generated on the photoelectric material 20, electrons are accelerated toward the fluorescent material 30 because the voltage is applied, and light is generated when the electrons hit the fluorescent material 30. Light is sent toward the photoelectric material 20 after hitting the reflecting face 40. Part of the light generated by the fluorescent material 30 is sent to the photoelectric material 20 without hitting the reflecting face 40. If the quantity of this light is sufficient, no reflecting face 40 is required, and part of the light is extracted to the outside.  Part of the remaining light is sent to the photoelectric material 20 to generate electrons again, the electrons are accelerated to hit the fluorescent material 30, thus the luminescence of the whole device can be continued.

Abstract: PURPOSE:To obtain a permanent magnet where its corrosion resistance is high and its glass layer is excellent in durability, by causing the surface which contains specific amounts of rare earth elements, Fe and B and possesses the principal phase of a crystal structure of tetragonal system to have a base layer and further, the surface of the base layer to have a glass layer thereon. CONSTITUTION:An ingot which is obtained by casting an alloy containing 8-30at.% rare earth elements, 42-90at.%, and Fe 2-28at.% B is reduced to powder and is molded in a magnetic field and after sintering it, it is quenched to obtain a sintered compact. The compact is treated with aging in an inactive gas to obtain a permanent magnet. In order to improve the adhesive property of a glass layer at the surface of the permanent magnet, for example, a base layer is formed at a depth of 0.01-50mum by an electrolytic plating or the like. The glass layer formed at the surface of the base layer serves as a protective layer so as to improve the corrosion resistance. For example, a slurry having 40 parts of glass powder that is made by pulverizing a glass having a composition of 10SiO2-25B2O3-65ZnO; 10 parts ethylcellulose; and parts terpineol 50 is applied by dipping to the permanent magnet having the base layer and after drying it, it is burnt for an hour at 700 deg.C.

Title: Igniter for internal combustion engine provided with anti-reverse rotation circuit
Inventor: OGAWA TOMOYUKI
IPC: F02P11/02
Filed: 1987-12-24
Abstract: PURPOSE:To facilitate manufacture of a generator having an ignition power source coil and a signal coil by arranging an igniter such that an ignition block switch switches the section for blocking supply of ignition signal upon forward/reverse rotation of an engine and blocks supply of ignition signal only when the engine rotates reversely. CONSTITUTION:During an interval between time points when a signal coil 6 for detecting reverse rotation produces a negative polarity signal and a positive polarity signal respectively, an ignition block switch circuit 8 blocks supply of ignition signal through a trigger signal supply circuit 9. Since the section where the circuit 8 blocks supply of ignition signal does not lap over the section where a signal coil 3 for determining an igniting position produces an igniting position determining signal during forward rotation of engine, igniting operation is carried out with no trouble. Since the output from a signal coil 6 for detecting reverse rotation is inverted and a positive polarity signal is produced first during reverse rotation of engine, the ignition blocking switch circuit 8 operates upon provision of an igniting position determining signal from the igniting position determining coil 3 to block supply of igniting signal to an ignition coil 1. By such arrangement, manufacture of generator can be facilitated.
