Title: Cathode of electrode tube
Inventor: WATABE KEIJI
IPC: H01J1/20
Filed: 1985-04-05
Abstract: PURPOSE:To make it possible to obtain high current density by mixing Zr carbide given heat treatment in a vacuum within the range of a specific temperature with an alkaline earth metal oxide coating a substrate metal. CONSTITUTION:A substrate metal 1 mainly composed of Ni is coated with an electron radiation material layer 2 made of an alkaline earth metal oxide and heated by a heater 3 thereafter. In such a cathode, the alkaline earth metal oxide to be used is mixed with Zr carbide given heat treatment in a vacuum at 800-1,000 deg.C. When Zr carbide is mixed with the alkaline earth metal, the alkaline earth metal is reduced by Zr carbide for being fully and excellently activated thus being able to obtain electron radiation having high current density. At a heating temperature less than 800 deg.C, however, the alkaline earth metal is only slightly reduced while having a scanty effect. And at a temperature exceeding 1,000 deg.C, reducing force is strong while leading to a short life of a cathode.

Title: Semiconductor optical waveguide and its production
Inventor: SAKATA YASUTAKA
IPC: H01S5/12
Filed: 1995-03-30
Abstract: PURPOSE: To provide a low-reflection end face structure having excellent controllability and reproducibility by controlling the growth speed of clad layers in a waveguide direction by a method of selective growth of MOVPE in a semiconductor optical waveguide having a window structure for embodying the low reflection end face, thereby embodying a structure to obviate the occurrence of a difference in level in the clad layers. CONSTITUTION: A pair of SiO2 stripe masks are formed in the [011] direction on an n-InP substrate 101 at a spacing of 1.57μm. A multilayered structure including an active layer 104 is deposited by selective MOVPE on these regions of 1.5μm. At this time, the stripe mask spacings of the SiO2 are made zero in the regions of the window structure, by which the window structure is produced without executing etching of the semiconductor. The formation of the difference in level of the clad layers in the window region after the selective growth of the next clad layer 106 is prevented by previously forming the window region mask width larger than the width in the other regions.

Title: Formation of secondary battery having iron electrode
Inventor: IWAKI TSUTOMU
IPC: H01M10/28
Filed: 1983-04-25
Abstract: PURPOSE:To enable times of formation to be reduced and enable the method of manufacture to be simplified and its time to be shortened by using a large current in the initial stage and a small current in the last stage in carrying out discharging after charging is performed. CONSTITUTION:During the time when formation of a secondary battery having an iron electrode is performed after its assembly, discharging is carried out in which the current is gradually decreased within the range between 0.2-0.5C, which is the discharge rate of the initial stage, and 0.1-0.05C, which is the discharge rate of the last stage. As a result, time required for the formation can be greatly reduced especially when electrolyte is not sufficiently diffused into the iron electrode, for example, in the following cases: when a silver oxide electrode or the like in which voluminal expansion is caused by charging and discharging is used as a positive electrode; when the iron electrode touches a separator without allowing any space between a positive and a negative electrode in order to suppress the separation of active material in the electrodes which may be caused by repeating charging and discharging; and when the interelectrode distance is made small in order to achieve a high energy density.
