Title: Nonaqueous electrolyte battery
Inventor: JINNO MARUO
IPC: H01M10/0569
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery with an improved reservation property in charging in which generation of self-discharge caused by contact reaction between an electrode material and a nonaqueous electrolyte solution is suppressed by mixing a solvent consisting of a specific sulfonic compound with a solvent in a nonaqueous electrolytic solution. SOLUTION: A nonaqueous electrolyte battery is provided with a positive electrode, a negative electrode, and a nonaqueous electrolytic solution. A solvent of the nonaqueous electrolytic solution contains one or more kind of a solvent consisting of a sulfonic compound represented by a formula: R1 -SO2 -R2 (R1 , R2 represent different alkyl groups of C1-4 ). A content of the sulfonic compound ranges from 1 to 80% by volume desirably. When a carbonous material which can store/release a lithium ion is used for the negative electrode, a reaction with the nonaqueous electrolytic solution is suppressed further, so that a reservation characteristic of the nonaqueous electrolyte battery is improved further.

Title: Thermal recording material
Inventor: KANEKO MANABU
IPC: G03C1/498
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To obtain a thermal recording material in which stain is reduced while enhancing color reproducibility by adding a whiteness improving agent to a region where a free photoradical generating agent and a coloring matter are present. SOLUTION: A whiteness improving agent is added to a region where a free photoradical generating agent and a coloring matter are present. The whiteness improving agent includes a hydroquinone derivative, e.g. 2,5-di- sec-dodecyl hydrohydroquinone. Production mechanism of stain is not clarified but a subreaction other than discoloring of coloring matter may take place through the free photoradical upon activation of the free photoradical generating agent to color the subreaction products with yellow to produce yellow stain. Alternatively, the coloring matter may not be decomposed nor discolored sufficiently due to decomposition of the unreactive free photoradical generating agent and the insufficiently decomposed coloring matter may develop a color again as the time elapses. The whiteness improving agent blocks generation of stain at the white part.

Abstract: PURPOSE:To supply an output voltage stably by means of an input voltage as close as possible to a setting output voltage by employing a PNP transistor(TR) for an output TR of an output voltage setting circuit, applying feedback control to the PNP TR and obtaining a constant output voltage. CONSTITUTION:With an input voltage applied to an input terminal 1, a current flows to a TR Q6 and a resistor R4, the same current flows to TRs Q5, Q7 accordingly. The collector current of the TR Q7 flows to the base of a control TR Q9 to turn on the TR Q9. As a result, the base potential of the TR Q8 is lowered and the TR Q8 is turned on. With the TR Q8 turned on, the control TR Q3 is turned on via the emitter and collector and a TR Q9 is turned off. The output voltage setting circuit 8 is made stable by the feedback control. The band gap circuit 6 in this state utilizes a difference of the base-emitter voltage of the TRs Q1, Q2, a constant current devided by the resistor R3 is extracted from the output voltage setting circuit and an output voltage decided by the output voltage setting circuit is outputted to an output terminal 2.
