Title: Closed type lead storage battery
Inventor: HIGASHIMOTO KOJI
IPC: H01M50/40
Filed: 1988-11-11
Abstract: PURPOSE:To make it possible to restrain the lamination of an electrolyte without the lowering of battery performance by forming an electrolyte movement restraint region with a porous separator filled with an attractant.swelling substance having an attractableness and swelling property. CONSTITUTION:An electrolyte movement restraint region 10 is formed by filling a porous separator 9 with an attractant.swelling substance 11 having an attractableness and swelling property. Consequently since the substance 11 attracts an electrolyte to be swelled and closely adheres to the surface of electrode plates 2 and 3, the movement of the electrolyte in the interface between the region 10 and the plates 2 and 3 can be restrained. And since the region 10 by putting the substance 11 attracts the electrolyte, a cell reaction can be made to occur even in the region 10. This enables the lamination of the electrolyte to be restrained without the lowering of battery performance.

IPC: H02M7/12
Filed: 1988-11-12
Abstract: PURPOSE:To increase surge resistance by using two rectifying devices, which are connected in series and employed for connecting a neutral point, as Zener elements. CONSTITUTION:Both an internal surge and an external surge are absorbed through the series body of two Zener elements ZD7, ZD8 for connecting a neutral point. Consequently, clamp voltage is brought to the level of twice as high as Zener voltage, and kept constant both in case of the internal surge and the external surge. When the surges are generated, voltage at the level of the half of surge voltage is applied to the two Zener elements ZD7, ZD8 respectively. Accordingly, the level of peak voltage applied to one Zener element ZD7 (ZD8) is brought to the half of the peak voltage of the surges. Zener voltage is brought to the level of the half of clamp voltage.

Inventor: AKAI YOSHIMI
IPC: H05G1/02
Filed: 1990-10-24
Abstract: PURPOSE:To prevent deterioration in a CT image by a method wherein an X-ray source or an X-ray detection means is moved by a moving means to correct movement as caused by a thermal expansion of the X-ray source to set the X-ray source and the X-ray detection means in an initial relative position. CONSTITUTION:A moving means control section 8 picks up an electrical signal Vb detected and outputted with a sensitive part 14b of an auxiliary detection section 10b and an electrical signal Vd detected and outputted with a sensitive part 14d to control a moving means 4 so that an output difference therebetween is nullified. Subsequently, the moving means 4 moves an X-ray detector 10 in a direction of slicing under the control of a moving means control section 8 so that a sector X-ray beam 5 from an X-ray tube 3 always aligns the center of the X-ray detector 10. With an apparatus 1 thus arranged, even if an X-ray focus of the X-ray tube 3 moves in a direction of slicing by a thermal expansion, the X-ray tube 3 and the X-ray detector 10 can be maintained at an initial relative position relationship by the moving means 4 thereby obtaining a CT image better with limited generation of artifact regardless of continuous scanning.
