IPC: C08L101/00
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To develop a metal composition without releasing environmental pollutants such as SOx or halogens at the time of baking and establish a method for application thereof to a decoration of pottery, glassware, etc., an electrode, etc., of an electronic part by utilizing the metal composition. SOLUTION: A metal acetylide compound represented by the general formula M(- CE≡C-R)n [M is a metal atom; (n) is the valence of the metal atom M; R is a hydrocarbon group containing or without containing oxygen atom] is used as a metal source and kneaded with a resin or an organic solvent to produce a metal composition such as a metal liquid or a metal paste. Since the metal acetylide compound contains neither sulfur nor halogen elements, sulfurous acid gas or halogen gases are not released even by baking. Thereby, the compound is capable of contributing to the cleaning up of environment. Since the solubility thereof in organic solvents is high, the compound is suitable as a raw material for the metal composition.  Furthermore, 1a metal film formed after the baking has high smoothness, denseness, metallic lustrousness and electroconductivity, the metal film can be utilized for a decoration of a decorative article, an electrode, etc., of an electronic part.

Title: Converter
Inventor: KITAIZUMI TAKESHI
IPC: H02M7/48
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To reduce waveform distortion from the output current of a converter by enabling an auxiliary control circuit to make feedback control, based on the information from a control circuit which generates a signal for controlling a switching element upon receiving information from a current monitor, and the information from a resonance voltage detecting circuit which detects the primary-side resonance voltage of a high-frequency transformer. SOLUTION: An auxiliary control circuit 15 drives an oscillation circuit 16 upon receiving information fed back from the current monitor 9 of a control circuit 8 and a resonance voltage detecting circuit 14. Consequently, the switching waveform of a switching element 3 becomes such a waveform that its envelope is synchronized to a commercial alternating current and contains a high frequency. The commercial alternating current has a frequency of about 120 Hz and the high frequency is 20 kHz. In other words, the inside of the envelope is controlled at a density which is 100 times higher than that of the envelope.  Even when, for example, a load 12 fluctuates, therefore, the waveform of the output current Io of a converter can maintain the low-distortion sine wave of the commercial alternating current, because the information on the fluctuation can be detected instantaneously by means of the monitor 9 and detecting circuit 14.
