Title: Manufacture of cathode plate for lead-acid battery
Inventor: HENMI TOSHIO
IPC: H01M4/20
Filed: 1981-12-24
Abstract: PURPOSE:To increase strength of an active mass of a cathode plate before formation to increase production efficiency by converting lead oxide into lead carbonatre using carbon dioxide gas when the paste for the cathode plate is kneaded. CONSTITUTION:Part of lead oxide in a paste is converted into lead carbonate with carbon dioxide gas which evolves by reaction of dilute sulfuric acid with barium carbonate used as an anti-shrinkage agent for a cathode plate when the paste is kneaded, or during water kneading of convertional paste kenading process, carbon dioxide gas is blown in the paste to convert lead oxide into lead carbonate. By either way, the crystal of lead carbonate is uniformly generated in the paste to increase strength of an active mass. Therefore, since strength of the active mass of a cathode plate is substantially increased, coming off of the active mass in handling in a drying process or in a stacking in an assembling process is prevented, and production efficiency is improved.

Title: Method and apparatus for transmitting data signal
Inventor: MICHELS-KROHN KARL-HEINZ
IPC: H04L12/42
Filed: 1986-09-11
Abstract: A method and apparatus for transmitting data between a number of control devices which are connected to each other by at least one clock-controlled loop, which is operated directionally dependent, are disclosed which cause a transmit authorization signal to be sent via the loop from control device to control device which places each control device, upon receipt thereof, in a transmit authorization status. A control device receiving the transmit authorization signal emits data signals to be transmitted via the loop, with a receiver address identifying a selected other control device intended to receive the data signals, before forwarding the transmit authorization signal to another control device. The control device which transmitted the data signal is then switched to an acknowledgement signal reception status. If the intended other control device receives the data signals correctly, it sends an acknowledgement signal to the transmitting control device. The transmitting control device is maintained in the acknowledgement signal reception status for a time no longer than arrival of a further transmit authorization signal. If the transmitting control device receives the acknowledgement signal within this time, it is then switched to a status enabling renewed emission of further data signals. If no acknowledgement signal is received within this time, the transmitting control device is switched to an error status for either reporting the error or initiating steps to correct the error.

Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To provide the control device of a brushless motor for enabling advance angle control for allowing the switching time of the conduction state of a switching element to precede the change time of a rotor magnetic pole detected by a magnetic sensor, regardless of software.
