Title: Negative electrode material for lithium secondary battery and lithium secondary battery
Inventor: MATSUYOSHI HIROAKI
IPC: H01M4/587
Filed: 1994-07-14
Abstract: PURPOSE:To obtain the lithium secondary battery, which has excellent energy density, excellent discharging characteristic and excellent cycle characteristic, by using carbide, which is obtained by baking Brooks-Taylor type mesophase small spherical body, as the negative electrode material. CONSTITUTION:Brooks Taylor type mesophase small spherical body is baked in the nitride atmosphere so as to obtain the Brooks-Taylor type mesophase small spherical body carbide at 1.50-2.00 of true specific gravity. It is used for the structural member of a negative electrode of a lithium secondary battery. Raw material of MCMB (meso carbon micro beads) of the Brooks-Taylor type mesophase is manufactured form coal tar or pitch. Spherical body of type MCMB has the structure that condensed multi-ring aromatic molecular are vertically laminated in the optical axis direction. Consequently, since the end surface of carbon is arranged vertical to the surface of the spherical body of MCMB, lithium ion can easily go in and out at the time of charge and discharge, and the diffusing speed thereof is considered high.

Title: Indoor type temperature sensor
Inventor: FUJII KOICHIRO
IPC: F24F11/02
Filed: 1985-07-23
Abstract: PURPOSE:To uniquely determine the correction value to compensate for a temperature increase due to the internal heat generation by covering the entire surface of the base for wall installation with the heat insulating material on the side of the circuit base plate to thermally insulate the circuit base plate and the base for wall installation so that the heat generated in the internal circuit may not escape from the wall installation base. CONSTITUTION:The temperature sensing unit 106 normally comprises a thermistor etc., and a room temperature to be measured is converted to a resistance value which is converted into a voltage signal etc. by a sensor circuit, but an amount corresponding to a temperature increase resulting from the internal heat generation of the sensing circuit is subtracted as a correction value. In determining a correction value, since the entire surface of the wall installation base 101 is covered with the heat insulating material 102 on the circuit base plate 105 side, the amount of generated signal heat which escapes from the wall installation base 101 can be negligible. Therefore, a correction value for the temperature increase can uniquely be determined without being affected by the material and structure etc. of the wall to which the sensor is attached.
