Title: Secondary battery using carbonaceous material
Inventor: NAKAJIMA TAKAYUKI
IPC: H01M4/587
Filed: 1986-11-08
Abstract: PURPOSE:To obtain a compact, lightweight power source with particularly excellent cycle characteristics and self-discharging characteristics by using n-doped body of specific powder carbonaceous material as an active substance for negative electrode. CONSTITUTION:In a nonaqueous secondary battery having n-doped body of specific powder carbonaceous material as an active substance for the negative electrode, a specific surface area A (m<2>/g) of the carbonaceous material measured by BET method is in the range of 0.1<A<100. The crystal thickness Lc (Angstrom ) measured by x-ray diffraction and the true density rho (g/cm<3>) should satisfy conditions: 1.70<rho<2.18 and 10<Lc<120rho-189. The grain size distribution of carbonaceous material in a range from 0.1 to 50 mum is 90% or more in volume and the initial current efficiency of active substance is 50% or more. If the specific surface area A (m<2>/g) of the carbonaceous material measured by BET method is less than 0.1 m<2>/g, smooth electrochemical reaction on the electrode surface can hardly proceed because of the too small surface area. If the specific surface area is 100 m<2>/g or more, disadvantageous degradation of characteristics occurs regarding cycle life, self-discharge and current efficiency.

Title: Timer device
Inventor: NIINUMA SHIGERU
IPC: G04F3/00
Filed: 1984-12-19
Abstract: PURPOSE:To improve the economy and reliability by improving an automatic supervisory circuit of a timer so as to prevent the increase in the number of confirming times attended with the number of timers to be checked. CONSTITUTION:In inputting a check input signal 1 to a check input terminal TC1, a digital timer T1 and a confirming timer Tx give logical 1 at their output terminals after a prescribed time and the timing of the Tx is set to a momentary position, its output causes logical 1 and gives it to the input terminal of an AND1 momentarily. Since logical 1 is inputted by a NOT to the other input of the AND1 until the setting time comes by the timer T1, the output of the AND1 is logical 1 to set an F/F and gives logical 1 to the input of an AND2. When the output terminal of the timer T1 gives logical 1 after the setting time of the timer T1, the input level of the AND1 via the NOT is logical 0 to release the set input of the F/F, logical 1 is given to the other input of the AND2, the output of the AND2 goes to logical 1, an OP being a check result confirming output gives logical 1, and the result of check is discriminated as 'good'. This is similar when the check input signal 1 is given to a check input terminal TCn.
