IPC: H01M4/08
Filed: 1990-03-30
Abstract: PURPOSE:To form a battery having a long discharge time and less dispersion by mixing and stirring a plurality of powders having different bulk densities with a binder by means of a mixer having a horizontally rotating blade and a vertically rotating blade. CONSTITUTION:Manganese dioxide is used as an active material, carbon as a conductive material, and a diluted fluorine resin as a binder. Manganese dioxide is first mixed with carbon, then the diluted binder is injected, and, for example, a horizontal rotating blade 1 is set to about 150rpm, and a vertical rotating blade 2 to about 1000pm to conduct kneading for about 3 minutes. After completion of kneading, the mixture is discharged, and grading is performed after drying to form a powdery mixture. Hence, high bulk density and excellent flowability can be provided, and battery assembling process can be stabilized. A pellet is formed by use of the powdery mixture to form a battery, whereby a battery having a long discharge time and less dispersion can be obtained.

Title: Communication terminal
Inventor: KOJIMA HIDEYUKI
IPC: H04N1/32
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a communication terminal with a function of urging an opposite party to make redialing according to a caller number notice method, when the opposite party making a call without the caller number notice is a facsimile terminal. SOLUTION: An ID non-notice reason discrimination circuit 13 discriminates an ID non-notice reason from caller ID information sent from a caller via a line 12. When the discrimination result indicates that a call is not a number non-notice call, the processing continues to the usual communication flow. However, when the discrimination result indicates that the call is a number non- notice call, a communication control section 9 transmits a reception end signal to prepare for the reception of a call signal. Upon the receipt of the call signal, the line is closed to accept the call. Then communication according to a prescribed protocol is started. During a reply as a called station in a phase B, a CPU 1 causes the communication control section 9 to transmit a signal denoting 'to urge a caller to make redialing in accordance with a caller number notice method' to the caller.  After the transmission of this signal, the CPU 1 interrupts the communication by the protocol in the phase B before entering transmission of image information and sets a communication error.
