Title: Picture tube
Inventor: INABA MICHIHIKO
IPC: C23C8/10
Filed: 1985-07-22
Abstract: PURPOSE:To achieve a low PD level and produce a bright clear flat picture plane by using an intratubular part which is made by forming a black oxide film of spinel structure over the surface of an alloy base having a special composition with a layer containing a higher concentration of chromium than the alloy base interposed. CONSTITUTION:The picture tube of this invention includes an intratubular part which is made by forming a black oxide film of spinel structure containing chromium, nickel and iron over the surface of an alloy base composed of iron, 25-45wt% nickel and 0.3-10wt% chromium with a layer containing a higher concentration of chromium than the alloy base interposed. The content of Ni is adjusted to 25-45wt% in order to adjust the thermal expansion coefficient of the alloy base to at most 90X10<-7>/ deg.C. Ni contents of outside this range can not achieve a sufficiently low thermal expansion coefficient of the alloy base. Cr increases the thermal expansion coefficient of an Ni-Fe alloy and reduces its 0.2% yield strength which determines the moldability of the alloy. Since a CR content of 0.5 or higher suppresses the 0.2% yield strength of the alloy and a Cr content exceeding 10wt% increases the 0.2% yield strength, the content of Cr is restricted to 0.3-10wt%. The black film formed over the surface of the alloy base achieves improved thermal radiation.

Title: Electrostatic charger
Inventor: MIZOGUCHI TADASHI
IPC: G03G15/02
Filed: 1983-09-01
Abstract: PURPOSE:To enable progression and suppression of electric discharge by providing a grid for controlling space charge between a discharge wire and a screen grid. CONSTITUTION:An electrostatic charger consists of a discharge wire 1, a grid 2 for controlling space charge, a screen grid 3 and an outside frame shield 4. The influence of temp. on the corona start voltage at paired flat plates of a positive needle having a determined gap is such that the corona discharge voltage decreases as the temp. rises. The discharge gap length optimum for the electrophotographic process is therefore taken larger than the discharge gap length l1 shown in the figure and the impressed voltage is taken larger than the corona discharge voltage of a dotted line to meet said gap. If the corona start voltage increases with a decrease in temp., the voltage of the same polarity as the polarity of the voltage impressed to the wire 1 is impressed to the grid 2 and the substantially large voltage is kept impressed to the wire 1. The voltage on the grid 2 is changed in conformity with the temp. detecting circuit. The corona start is thus progressed by decreasing the voltage of the grid 2 when the temp. is low, and the corona start is suppressed by increasing the voltage when the temp. is high. The stable discharge hence stable charging characteristics is obtd.

Title: Formation of electrostatic latent image
Inventor: OKA KOUZOU
IPC: G03G15/05
Filed: 1982-09-17
Abstract: PURPOSE:To eliminate the need for Corotron, by applying a voltage between the conductive substrate and beltlike electrodes of a photoreceptor consisting of the conductive substrate, insulation layer, beltlike electrodes and photoconductive layer, and injecting electric charge in the photoconductive layer then maintaining the substrate and the electrodes at the same potential and exposing an image to the photoreceptor. CONSTITUTION:An insulation layer 2 of polyester, etc. is provided on a conductive substrate 1, and beltlike electrodes A1-A3 of Al or others are formed thereon, then a photoconductive layer 4 is provided thereon. A voltage is applied between the substrate 1 and the electrodes A1-A3 and electric charge is injected into the layer 4. The injected electric charge arrives at the surface of the layer 4 and is trapped thereon. If the electrodes A1-A3 and the substrate 1 are then set at the same potential, the state similar to the state when corona discharge is performed is realized. An image is exposed on the surface of such photoreceptor, by which the electric charge on the surface is neutralized in the incident part of light and an electrostatic latent image is formed. The need for Corotron is thus eliminated.
