Title: Manufacturing method of alkaline dry cell
Inventor: IWAI KENJI
IPC: H01M2/02
Filed: 2000-11-08
Abstract: PROBLEM TO BE SOLVED: To enhance production efficiency, a homogeneous coating work of an electroconductive coating possible, and improve the work environment in a manufacturing method of an alkaline dry cell to form an electroconductive film between a positive electrode mix and a positive electrode can. SOLUTION: After preheating the positive electrode can at a prescribed temperature only for a prescribed time, a water-based electroconductive coating material is coated and the electroconductive film is formed by making the electroconductive coatings dried at the prescribed temperature and only for the prescribed time. The positive electrode mixture is housed in the positive electrode can, and abutted on an inner wall of the positive electrode can via the electroconductive film. By this, because the water-based electroconductive coating material is coated and evaporation begins in a state that the inner wall of the positive electrode is kept at the high temperature, a drying time of the electroconductive coatings is made shorter.  Furthermore, because a surface tension of the electroconductive coatings becomes smaller and the coatings become easier to adhere to the inner wall of the positive electrode can, and sagging of the electroconductive coating just after coating becomes less. Furthermore, usage of an organic solvent harmful to the human body becomes unnecessary.

Abstract: PROBLEM TO BE SOLVED: To actualize an OFDM transmission system which can accurately estimate a SWEEP symbol start position in any transmission state and always perform synchronous detection without being affected by whether or not a reflected wave and a noise component are present. SOLUTION: The digital transmitter which uses an orthogonal frequency- division multiplex modulation system transmitting multiple kinds of synchronous symbol groups and multiple data symbols as a signal of frame constitution calculates a reference threshold for detecting the end part of a no-signal period wherein frame synchronism in the synchronous symbol groups is detected from the maximum and minimum values of mean electric power values by 1/2-symbols periods of a receive signal in a specific period, so normal synchronization with a main wave can be actualized in a short time in any transmission state under wider-range conditions without being affected by whether or not a reflected wave and a noise component are present.
