Patent JP-S62198878-A (JP)
Title: Image forming method
Inventor: WATANABE HARUO
IPC: G03G15/02
Filed: 1986-02-26
Abstract: PURPOSE:To improve the sensitivity of a photoconductive toner and to reduce the residual potential thereof by preliminarily electrostatically charging the photoconductive toner to a reverse polarity then charging the same to a prescribed polarity and irradiating light thereon. CONSTITUTION:The photoconductive toner 2 is sprayed uniformly over the entire surface on a conductive substrate 1 and the entire surface is electrostatically charged to the prescribed polarity (positive) by using a corona charger 3. The light is irradiated over the entire surface to decrease the positive charge. The photoconductive toner 2 is then charged to the reverse polarity (negative) side with about the same potential as the potential of the previous charge by using a corona charger 4 to execute image exposing. The photoconductive toner 2 in the part irradiated with the light so as to correspond to the image is made selectively conductive, by which the electrostatic charge is lost and the electrostatic attraction force to the substrate 1 is annihilated. The photoconductive toner 2 in which the charge potential remains is selectively transferred to a transfer substrate 5 by the electrostatic attraction force.

Title: Device for sealing cathode-ray tube
Inventor: HAYASHI AKIHIRO
IPC: C03C27/02
Filed: 1987-02-24
Abstract: PURPOSE:To obtain the title sealing device capable of preventing an abnormal temp. raise at a neck part and capable of remarkably reducing the oxidation level of an electron gun, by separately arranging the plural burner tips of a ring burner for welding the neck part and the stem part of the electron gun at the positions where the mutual interference between the flames can be avoided. CONSTITUTION:The burner tips 23 are separately arranged in plural directions so that the flame projecting directions do not interfere with each other, and a flame 36 is ejected from the tips. Since the flame 36 is moved along the outer peripheral surface of the neck part 12a by the rotation of the ring burner 21, the peripheral surface of the neck part 12a is uniformly heated. Excessive heating caused when the flames 36 are ejected and interfere with each other can be eliminated, and also the expansion of the flame can be prevented. By this method, since the abnormal temp. raise in the neck part 12a is eliminated, the oxidation due to the heating of the electron gun parts at high temp. is prevented. As the flame does not expand unlike the conventional method, the welded part of the neck part 12a is locally softened, the thickness of the welded part is decreased, cutting is facilitated, and the neck part can be surely welded to the stem part 11a.

Title: Mig welding method
Inventor: KIRIYUU KOUJI
IPC: B23K9/173
Filed: 1979-04-05
Abstract: PURPOSE: To decrease the displacements of elongation on the welding start side and end side and keep the material deterioration range low by forming the groove part divergent downward and convergent upward and affixing straps to the outside circumference of the groove part then inserting a wire and feeding inert gas thereby performing welding.  
     CONSTITUTION: With the welding works 1, 2 of good heat conductivity such as copper, the welding groove part 3 is formed to a trapezoidal shape which is divergent downward and is convergent upward. Strap members 4, 5 are affixed to both the side faces and bottom face of this groove part 3. A welding wire 6 is inserted into this groove part 3 and welding is started by supplying inert gas. This method eliminates the need for the releasing of the welding latent heat input through reinforcement of weld and enables the effective utilization of welding heat input. Hence, the material deterioration range may be made narrow, the displacements of the elongation of the weld zone reduced and the even elongation achieved.

Title: Photomagnetic recording medium
Inventor: SAITO ICHIRO
IPC: G11B11/10
Filed: 1985-03-04
Abstract: PURPOSE:To improve a shelf life by providing an intermediate layer formed by dispersing an Se compd. into a dielectric material. CONSTITUTION:This photomagnetic recording medium is laminated with at least the intermediate layer 2 and a photomagnetic recording layer 3 on a light transmittable substrate material 1 and has the intermediate layer formed by dispersing the Se compd. into the dielectric material. The effective temp. increase of the layer 3 is not possible if the film thickness of the intermediate layer 2 formed by dispersing the Se compd. into the dielectric material is too large or too small and therefore the intermediate layer is preferably formed to about 0.005-0.5mum thickness and is more particularly preferably set at the thickness at which the intermediate layer exhibits an antireflection function. The dielectric material constituting such layer 2 is, for example, an oxide such as SiO, SiO2 or ZrO2, nitride such as AlN, Si3N4, ZrN or CrN or sulfide such as ZnS or Bi2S3. The volumetric ratio of the Se compd. with respect to the dielectric material, when designated as (q), is preferably made in a q=5-90% range. The absorption of light increases at the value of (q) exceeding 5% and the medium is thermally unstable and such instability is disadvantageous in terms of recording sensitivity when the value is below 5%.

Title: Transmitting device
Inventor: NAKATANI TADASHI
IPC: H03M5/18
Filed: 1987-02-25
Abstract: PURPOSE:To prevent a pulse transformer from heating and being a very high temperature by preventing a driving circuit from continuing to turn on for a certain constant time or above even when a control circuit is troubled and the condition that a signal to cause a pulse current to flow at the pulse transformer is outputted is continued. CONSTITUTION:When a high level continues to be outputted as an output (a) of a control circuit 1, a current i1 to flow at a capacitor 16 comes to be a differentiated waveform port. When the current i1 approaches to 0, a transistor 5 is turned off. At this time, a current to flow at the collector of the transistor 5, first, flows by 71.4mA only due to the function as the transformer of a pulse transformer 9, soon, the pulse transformer generates a magnetic saturation, the function as the transformer is eliminated, and a current limited only by the direct current resistance of a secondary coil starts to flow at 500 mA. Since the current i1 to flow at the capacitor 16 approaches 0, and then the transistor 5 is turned off, the collector current of the transistor 5 is also returned to 0. Thus, the heating of the pulse transformer caused by the trouble of the control circuit can be prevented.
