Title: Picture editing for electronic copying machine
Inventor: SUZUKI TAKANOBU
IPC: G03G15/043
Filed: 1986-10-15
Abstract: PURPOSE:To register plural graphics corresponding to a designated area with only continuously inputting the coordinate of points by comparing the coordinate of a start point and that of a point inputted last among inputted plural points and specifying an area surrounded by the coordinate of plural points which have been inputted till then as the area for editing an original. CONSTITUTION:For inputting plural graphics, the coordinate of the inputted point is compared with that of the start point of respective graphics. If the inputted point is near the start point, the input of the graphic corresponding to one designated area is judged to be finished, and the graphic is automatically registered, whereby a system shifts to the input of the next graphic. Consequently, a user does not need to register and operate the graphic at every graphic. If the points are inputted continuously, plural graphics are automatically registered. Thus, the operation at the time of inputting plural graphics is simplified and plural graphics can be easily inputted. Furthermore, operational errors can be reduced.

Title: Manufacture of sealed lead-acid battery
Inventor: HASEGAWA TOSHIAKI
IPC: H01M4/22
Filed: 1992-09-16
Abstract: PURPOSE:To prevent the oxidation of a negative electrode by oxygen gas without filling a battery with the hydrogen gas and oxygen gas generated by electrodialysis of water, and prevent a reduction in capacity by covering, in the end of battery can formation of electrode plate, an exhaust hole provided on a lid with a flat blocking member opened and closed by a small gas pressure in the battery. CONSTITUTION:Formation is stopped after a determined time from the start of formation, an exhaust hole 5 is covered with a flat blocking member 8, and, thereafter, the formation is again performed, for example, for one hour. At this time, the blocking member 8 can be opened by a slight rise of battery internal pressure. When the formation is conducted in the state where the exhaust hole 5 is covered, thus, the gas generated by electrodialysis of water easily opens the blocking member 8, and the gas is almost released to the outside of the battery through the exhaust hole 5. Oxygen gas is absorbed by a negative electrode 2. Although the lead of the negative electrode is oxidized to form lead oxide, the formation is continued so that the lead oxide can be returned to lead thereby.

Title: Target for magnetic recording medium and production thereof
Inventor: AIDA MICHIYOSHI
IPC: G11B5/85
Filed: 1990-09-19
Abstract: PURPOSE:To efficiently remove the impurity elements of the target material for magnetic recording and to improve the magnetic characteristics of films by adding <=1wt.% rare earth metal into target constituting elements during the melting of the elements and confining the residual concn. of the rare earth metals in the target to <1wt.%. CONSTITUTION:The target material which is previously melted in a vacuum or inert gaseous atmosphere is subjected to a molten metal treatment to add <=1wt.% rare earth metal into the target material and the residual conc. of the rare earth metal in the target is regulated to <1wt.% in order to more efficiently remove the impurity elements contained therein. The rare earth metal added into the molten metal in the vacuum and inert gaseous atmosphere turns to the oxide of the rare earth by reacting with the oxygen existing in the molten metal. The oxide existing in the molten metal is wholly or partly reduced by the rare earth metal. The other impurity elements move together with the oxide of the rare earth as slag to the outside of the molten metal, i.e. casting surface and the impurity elements in the molten metal are expelled. The impurity elements in the target are easily and efficiently removed in this way and the magnetic recording medium having the excellent magnetic characteristics is produced.

Title: Neural circuit element
Inventor: ASAI MITSUO
IPC: G06N3/06
Filed: 1991-09-26
Abstract: PURPOSE:To realize a large-scale artificial neural net by asynchronously operating and compact neuron circuits. CONSTITUTION:The output of a neuron is expressed by the same pulse as a living body, and its degree of excitement corresponds to the pulse density of the output. Since the sum of products between each neuron and a weight value is obtained as an electrostatic capacity, the internal energy of the neuron corresponds to the potential of the electrostatic capacity. When the neuron excites to increase the internal energy, that is, when the potential of the electrostatic capacity 2 rises to reach a threshold, the electric charge of the electrostatic capacity 2 is discharged by a switch element 4. The threshold element can be realized with an inverter circuit. The potential change of the electrostatic capacity 2 is outputted to the outside by a transmission circuit, for example, inverter circuits 5 and 7 to output pulses whose density corresponds to the internal energy.
