Abstract: PROBLEM TO BE SOLVED: To improve the cycle life-time characteristic of a charged battery, by changing over its charging current into a second current as responding to its kind, when the differential value of its voltage in the case of charging it by a first charging current exceeds a predetermined value. SOLUTION: When determining that a comparison value ΔVi-06 of a data Vi-06 preceding the present data by six sampling times which are stored in a battery-voltage storing means 531 exceeds a stored data ΔVmin of the minimum voltage increase value associated with the comparison value ΔVi-06 by a value not smaller than a predetermined value K, determining that a charged battery 2 has been charged to the vicinity of its fully charged state, a signal fed from a battery-kind determining means 6 is inputted to an input port 58 of a microcomputer 50 to determine whether the charged battery 2 is a nickel-hydrogen battery or not.  When the charged battery 2 is a nickel-hydrogen battery, a signal LOW is inputted to the input port 58 of the microcomputer 50, and reversely, since a signal HIGH is inputted to the input port 58 when being a nickel-cadmium battery, whether the signal LOW is inputted to the input port 58 or not is determined. When determining that the signal LOW is inputted to the input port 58 and the charged battery 2 is a nickel-hydrogen battery, its charging current is reduced to improve the cycle life-time of the charged battery 2.

Title: Multiple address communication system
Inventor: TAKAHASHI HIDEHIRO
Filed: 1986-06-19
Abstract: PURPOSE:To decrease the time required for information transmission by generating a table described with a request degree at each reception station and applying retransmission based thereupon thereby sending information surely to the reception station having high necessity of information. CONSTITUTION:A transmission station 1 refers to a table 5 to decide whether or not a retransmission request signal is a significant retransmission request and sends the same information repetitively until the significant retransmission request is lost. The information is split with respect to information transmission to form plural frames and if retransmission is applied at each frame, or a transmission station decides it no significance regardless of retransmission requests by a reception station 4x to a M-th frame FM and if no other significant retransmission request exists, the transmission station sends a frame FM+1. In this case, it is clear that the station 4x cannot complete the said communication. Thus, the transmission station rewrites the table to set a setting value Nx relating to the station 4x as 0 and it is decided that the retransmission request sent from the station 4x is not significant.

Title: Rolling bearing
Inventor: KITAMURA MASAYUKI
IPC: F16C33/62
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To elongate a life under the vibration and impact environment, by using a steel for bearing, including carbon and chrome as the main additional elements, and including a specific amount of silicon, as a material of a fixed ring, and specifying the amount of the residual austenite after the quenching and tempering. SOLUTION: A fixed ring exposed under the vibration and impact environment, is made of a steel for bearing, comprising carbon and chrome as the main additional element, and including 0.15-0.35% of silicon, as a material, and the amount of the residual austenite just under a bearing face after the quenching and tempering, is controlled to be not more than 8%. The residual austenite is unstable in texture under the vibration and impact environment, and the yield strength is low, so that the micro plastic deformation is easily generated, and further the partial change of texture and the cracking are easily generated by the vibration and the impact when the amount of the residual austenite is over 8%. Further the loading circle at the fixed ring side is constant, so the vibration and the impact have high influence, and the life of a bearing is determined by the damage of the fixed ring.  That is, the long life can be obtained under the vibration and impact environment without increasing the size of the bearing.
