Abstract: PURPOSE:To improve the density in the vertical direction of a picture by increasing the number of apparent horizontal scanning lines in the vertical direction even if the spot diameter of an electron beam becomes smaller. CONSTITUTION:The consitution provides cathodes 1R, 1G and 1B which emit electrons, and the first-fourth grids 2-5 which draw out electrons respectively from the cathode 1 and converge them through action of an electron lens, further accelerate them to make them collide with a phosphor screen as electron beams 6R, 6G and 6B, whereby each grid 2-5 is provided with pass holes 7R- 10R, 7G-10G and 7B-10B for the purpose of allowing passage of electron beams 6R, 6G and 6B respectively, said pass holes are prepared in pairs respectively in the vertical direction with the fixed interval to form the electron beams 6R, 6G and 6B in pairs in the vertical direction. When the electron beams 6R, 6G and 6B, which are thus formed in pairs in the vertical direction, are made to collide with the phosphor screen, the vertically separated horizontal scanning lines in pairs can be thereby displayed simultaneously on the phosphor screen.

Title: Producing device for magnetic recording medium
Inventor: MATSUZAKI SOUICHI
IPC: G11B5/85
Filed: 1982-04-23
Abstract: PURPOSE:To prevent the electrostatic charging of a substrate, by irradiating an electron beam to an evaporating source at the incident angle to the extent that the reflected electron generated when the electron beam is irradiated to a ferromagnetic metal does not stick on the substrate or above. CONSTITUTION:A cylindrical vacuum vessel 1 is maintained at about 10<-5> Torr degree of vacuum. A substrate 3 consisting of a beltlike polymer molding of polyester is supplied from a feed roll 2, moves along the peripheral surface of a cylindrical can 4 and is taken up on a take-up roll 5. The electron beam irradiated from an electron gun 9 is deflected by a magnetic field generating part 10 and is irradiated at a prescribed incident angle to an evaporating source 7. The incident angle of the electron beam to a ferromagnetic metal 8 is increased so that reflected electron 12 reflects at a larger refrection angle and sticks hardly on the substrate 3. The electrostatic charging of the substrate by the reflected electron of the electron beam is thus prevented; therefore, the taking up of the substrate is made easy.

Title: Driving circuit of light emitting diode
Inventor: AKUTSU MASAHARU
IPC: H01L33/00
Filed: 1979-05-31
Abstract: PURPOSE:To reduce the number of parts used in the light emitting diode driving circuit by forming a circuit for controlling the light emission of two LED with one transistor. CONSTITUTION:When no control voltage is applied to the control voltate input terminal 8 of a transistor Tr1, the transistor Tr1 is turned off. Therefore, an LED3 does not irradiate a light. On the other hand, since a voltage necessary to irradiate light is applied through a diode 7 to the LED4, the latter irradiates light. Then, when a control voltage is applied to the control voltage input terminal 8 of the transistor Tr1, the latter is turned on to cause the LED3 to be applied with a voltage necessary for emitting the light thereto. However, since the LED4 receives a voltage lower than the voltage necessary for irradiating the light, it stops irradiating the light. In this manner, the LED3, 4 are alternatively irradiated with one transistor.
