Title: Cutting tool and manufacture of it
Inventor: MATSUBARA MASARU
IPC: B23B27/14
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To provide a cutting tool excellent in the fracture resistance of a cutting face when cutting hard material at a low cost by orienting the majority of whiskers in the direction crossing the cutting face. SOLUTION: This cutting tool, made of ceramics as matrix in which whiskers are scattered, has high toughness. Since the majority of the whiskers are oriented in the direction crossing a cutting face, a crack on the cutting face of the cutting tool, which is caused by the back component of cutting resistance, is restrained from propagation due to the pullout effect of these whiskers and the absorption of energy. As a result, the fracture of the cutting face is restrained. Therefore, it is desirable that all the whiskers are oriented in the direction crossing the cutting face, but if only the majority of whiskers are oriented to such a direction, fracture resistance can be mere improved than in the case where whiskers are randomly oriented.

Title: Charger for assembled battery
Inventor: SHINPO TOSHIYA
IPC: H02J7/02
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To efficiently charge a battery set efficiently without overcharging each battery by cutting off the connection between the battery and a charge circuit thereby stopping the discharge, when the terminal voltage of each battery reaches the second reference voltage. SOLUTION: When the voltage of some terminal of batteries 1a-1c reaches the first reference voltage, the discharge to the whole of an assembled battery 2 is stopped, and a discharge circuit is connected to each battery 1a-1c, and they are discharged individually. After that, when the terminal voltage reaches the second reference voltage, the discharge circuit is cut off from the battery to stop the discharge. As a result, the residual capacity of charge of each battery 1a-1c is made even to zero each. Accordingly, it becomes possible to charge each battery 1a-1c equally, and it becomes possible to prevent the overcharge of the specified battery caused by the difference of the residual capacity of the charge.

Title: Optimization system for enquiry of database
Inventor: UIMIN DEYU
IPC: G06F17/30
Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To provide a means which optimizes database retrieval from a multi- database system. SOLUTION: A database inquiry tree is reconstructed by performing an optimizing process in two steps for optimizing inquiry/response time. In the first optimizing step, a linkage tree which has a route inquiry node, a plurality of low-order inquiry nodes, and a plurality of table nodes each of which has left- and right-side slave sub-trees and is deep on the left side is generated. Then the response time of the route and low-order nodes and the access/response time to each table node are estimated. In the second optimizing step, the linkage tree is transformed into a balanced linkage tree by using the response time data so that the costs of the left-side slave sub-trees can substantially become equal to those of the right-side slave sub-trees. Finally, data are fetched from a related data base in response to the inquiry corresponding to the balanced inquiry tree.
