IPC: H02J7/02
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent the misjudgment of charge completion by comparing the voltage difference between the first voltage on power source side and the second voltage on secondary battery side at the time of break of a charging current and the voltage of the negative terminal of the secondary battery severally with the reference voltage thereby controlling charging. SOLUTION: A charging controller 27 switches the line over to, for example, the side of the contact a of a reference power source 25a by operating a reference power changeover switch 26. Then, the charging controller 27 starts quick charging and also struts a timer, and detects whether the voltage of the negative terminal of the secondary battery 21A has fallen under the earth voltage or not, and outputs a detection signal SB to a charging controller 27. The charging controller 27 terminates the quick charge after timer stops when the detection signal is low, that is, when the voltage of the negative terminal of the secondary battery 21A is higher than the earth voltage. Hereby, even if a plurality of secondary batteries 21A are charged in parallel, the misjudgment of the termination of charging can be prevented.

Title: Thermal condition stabilization device for machine tool
Inventor: TOMITA TAMAKI
IPC: B23Q11/14
Filed: 1975-08-28
Abstract: PURPOSE:Oil temperature is controlled comparing with atmospheric temperature in such a way that thermal strain of machine tool produced by the temperature rise through circulating oil own, can be prevented. CONSTITUTION:When temperature difference is negative comparing with the setting value in the case of morning, a relay CR2 actuates and its contact point Cr2 closes so that electricity is charged to a heater 9 to heat oil and when designated temperature difference is obtained, the heating stops. When oil for oil hydraulic driving device works, its temperature rises suddenly so that temperature difference between oil and atmosphere is positive over setting value and a relay CR1 actuates. Then, closing its contact point Cr1, oil is cooled through the drive of a motor 8 of a cooler 7. Thus, oil temperature can be controlled always in comparison with atmospheric temperature. For this reason, machine remains constant thermally whole day for avoiding the variation of product accuracy.

Abstract: PURPOSE:To prevent a part of a picture from being eliminated together with a frame part because of proximity or overlap between the picture and the frame part by scanning a line sensor on main scanning lines in both directions to obtain coordinates of edges of the picture and detecting the variation of coordinates for the same edge and determining the extent of entrance/approximation to the picture side of the frame part to be eliminated in accordance with this variation. CONSTITUTION:When the picture is read from the left to the right by a line sensor 30, coordinates of the left edge detected for entrance from a black frame to the picture are in the picture and are not accurate if the picture is close to the black frame, but coordinates of the right edge detected for entrance from the picture to the black frame are not affected by the picture at all. when the picture is read from the right to the left, coordinates of the right edge may be in the picture and are not accurate, but the left edge is accurately detected. That is, the variation of coordinates of the detected edge is very large when the picture is close to or overlaps the black frame, but it is small when the picture is sufficiently distant from the black frame. Thus, the extent of entrance/approximation to the picture side of the range to be eliminated is controlled in accordance with the variation to prevent the picture from being eliminated together with the picture.
