Title: Discharging device in magnetic field
Inventor: KAGEYAMA KATSUHIRO
IPC: C23C14/35
Filed: 1982-02-15
Abstract: PURPOSE:To form a strong film having good adhesion by leading sputtering atoms generated by crossed field discharge to the outside of a discharging device through an aperture of an anode and coating the inner wall face of a vacuum container. CONSTITUTION:When high voltage is applied between an anode 1 and a cathode 2 in a vacuum container, magnetron discharge is generated and continued at a part formed by the inner face of a tube, i.e. an anode, and the anode side surface of the cathode 2. The surface of the center of electrode 2b of the cathode 2 is made of a coating material, for instance, titanium, and ions generated by discharge collide with the electrode 2b and sputter the surface material. The sputtered material penetrates the aperture of the anode 1, goes to the outside of the anode 1, and deposits on the surface of solid around the anode 1 and cathode 2 and performs coating. Covers 16 are provided on supports 3, 5 that support the anode 1 and cathode 2 to protect the penetrated surface of the vacuum container from pollution due to sputtering atoms.

IPC: H01M10/05
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To provide a secondary battery indicating a good discharge characteristic when lithium manganese oxide having a spinel structure is used for a positive electrode, by containing a specific amount of malonic diester in organic electrolyte. SOLUTION: Organic electrolyte contains 0.5-3.0 vol% of malonic diester. Preferably, the malonic diester is diethyl malonate or di-n-propyl malonate. Since the organic electrolyte contains the malonic diester, a cycle characteristic is greatly improved. The malonic diester decomposes on a negative electrode surface during charge, good coating for accelerating going in/out of lithium ions is formed. As solvent of 97-99.5% other than the malonic diester, for example, cyclic carbonate class such as ethylene carbonate, chain carbonate class such as dimethyl carbonate or diethyl carbonate, lactone class such as γ- buthrolactone, or composite solvent such as sulfolane is used.

Abstract: PURPOSE:To provide the high sensitivity frequency modulator whose linearity is excellent and which is operated stably through the configuration offering small size and ease of manufacture by modulating an intensity of an impressed DC magnetic field with a signal so as to vary a wavelength of a magnetostatic wave. CONSTITUTION:A ground plate 8 is adhered to a rear side of a dielectric board 7 and an input electrode 9 and an output electrode 10 for a strip line are arranged opposite to each other at a required magnetostatic wave propagation interval on the front side.

Moreover, when a magnetostatic wave (k) is generated in the thin film 11 whose electrode 9 receives a required high frequency electromagnetic wave, the magnetostatic wave (k) propagates in the thin film 11 at a right angle to the electrode 9 and reaches the output electrode 10. Then, a frequency modulation output high frequency electromagnetic wave converted from the magnetostatic wave (k) subject to phase modulation is extracted from the electrode 10 during propagation. As a result, the high sensitivity frequency modulator whose linearity is excellent and which is operated stably through the configuration offering small size and ease of manufacture is obtained.
