Abstract: When a short circuit occurs in a lithium-ion secondary battery, a short circuit current is reduced to suppress temperature rise of the battery. In order to solve the above problem, a lithium-ion battery of the present invention includes an electrode having a mixture layer and a heat resistant layer disposed on the mixture layer and containing ceramic particles. The heat resistant layer includes a crosslinked resin, and the amount of the crosslinked resin is less than 10% by weight with respect to the sum of the amount of the ceramic particles and the amount of the crosslinked resin.

Abstract: A lithium ion battery includes: a positive electrode capable of occluding and emitting lithium ions; a negative electrode that is capable of occluding and emitting lithium ions; a separator disposed between the positive electrode and the negative electrode; and an electrolytic solution. The negative electrode of the lithium ion battery is coated with a lithium ion conductive polymer. The lithium ion battery maintains high-temperature storage characteristics at temperatures of 50° C. or more and output characteristics at room temperature of the lithium ion battery are improved.

Abstract: A lithium secondary battery is intended to suppress deterioration upon storage at high temperature of 50° C. or higher without deteriorating the output characteristics at a room temperature. The battery includes a positive electrode capable of occluding and releasing lithium ions, a negative electrode capable of occluding and releasing lithium ions, a separator disposed between the positive electrode and the negative electrode and an electrolyte, in which the electrolyte contains a compound represented by formula (1) (R?O)nSiR4-n??(Formula 1) where R? represents an alkyl group, R is selected from hydrogen, an alkyl group, an alicyclic group, and an aryl group, each of R? and R may be identical or different from each other, the alkyl group has a straight or branched chain having fewer than 10 carbon atoms, and n is an integer of 1 to 3, and a compound having a polymerizable group in the molecule.

Abstract: In a developing apparatus, a developing roller has a toner layer formed on a surface thereof, which toner layer is brought into contact with a photoconductor. A magnetic conveying roller having a magnet body is arranged rotatively close to the photoconductor. A regulating plate is provided at an outer periphery of the conveying roller.

Abstract: A control system for a pen-input type computer is capable of designating character kinds and character codes for each field in a screen that are registered in advance as an input field attribute of the pen-input type computer which is characteristic of each field. In this case, the combination of recognition candidates for recognizing input hand-written characters and the registered character kinds and character codes can be additionally registered. The input field attribute can be customized on the basis of the combination. Alternatively, when characters are input by moving a plurality of input pens on a screen, the control system is capable of imparting an identification code or a security level data to each input pen, so that data from the input pens can be distinguished from each other.
