摘要： An image forming member, e.g. a pen or a cutter (for cutting image patterns), which member requires to be lowered onto and applied with a given pressure to a writing surface, is controlled in two modes. In a position control mode, the image forming member is controlled by means of a closed loop circuit by which it is lowered and positioned at a very small distance off of the writing surface. In accordance with a second, pressure control mode, the image forming member is controlled by means of an open loop circuit. With the aid of the open loop circuit the member is lowered and then applied with a given pressure to the writing surface. Thus, accurate and rapid controlling of such an image forming member is achieved.

摘要： A magnetic field distribution measurement device (1) provides a non-contact magnetic field measurement on a subject's chest at a plurality of coordinates and forms therefrom time-series magnetic field distribution data. A first arithmetic device (2) in response generates image data representing a three-dimensional, intramyocardial current density distribution. A second arithmetic device (3) receives a plurality of tomographic image data separately obtained by a tomographic diagnosis apparatus and processes the data to generate three-dimensional, anatomical image data. A display device (4) receives these data and displays on an anatomical image an image representing an intramyocardial current density. This can facilitate identifying an anatomical, positional relationship of an abnormal, electrical reentry circuit caused in heart muscle. Furthermore, the anatomical image may be replaced with an image representing a normal stimulation propagation circuit and serving as a template.

摘要： A battery pack which is constituted by a plurality of lithium secondary batteries and which can prevent performance deterioration and has a long life is provided. The battery pack is manufactured by connecting in series four lithium ion batteries in which a lithium cobaltate is used for a positive active material and an amorphous carbon is used for a negative active material. In the battery, a percentage of the difference between positive electrode charging capacity and negative electrode charging capacity to capacity of the lithium secondary battery was set to 6%. The SOC difference among the four batteries was adjusted to 6 points or less. Even a battery having a low SOC is full charged, lithium oversupplied does not exceed a lithium amount capable of being occluded by a negative electrode at a battery having a high SOC, and thereby the active material does not deteriorate.
