Title: Organic electrolyte secondary battery
Inventor: FURUKAWA SANEHIRO
IPC: H01M10/052
Filed: 1984-02-29
Abstract: PURPOSE:To obtain a secondary battery having good charge-discharge cycle performance and good leakage resistance by using a negative electrode made by binding lithium alloy powder with gelled electrolyte. CONSTITUTION:A negative electrode 6 made by binding lithium alloy powder with gelled electrolyte is used. For example, a mixture of small lithium pieces and aluminium powder is heated in an atmosphere of argon at 600 deg.C for several hours, and after cooling, it is crushed to form powder. The alloy powder obtained is put into distilled 1,3-dioxolane, then lithium tetrafluoroborate is gradually added as the solution is stirred. After standing several hours, lithium-aluminium alloy powder bound with gelled electrolyte is taken out and pressed in a desired dimension to form a negative electrode 6. Since mechanical strength is increased with gelled electrolyte, charge-discharge cycle performance is improved. By using gelled electrolyte as binder, a large amount of electrolyte exists on the surface of negative active material and reaction effficiency of negative active material is increased.

Title: Voltage comparator circuit
Inventor: NAGASHIMA YOSHITAKE
IPC: H03K3/0233
Filed: 1978-04-05
Abstract: PURPOSE:To secure limitation for the changing range of the output voltage within the range in which the input voltage increases or decreases to be applied effectively to the driving source actuating the relay by providing the differential amplifier circuit to perform the comparison between the input voltage and the set voltage. CONSTITUTION:The bases of transistor Tr10 and 11 forming the differential amplifier circuit are connected to emitter 1a of Tr1 and set voltage V2 respectively; and the bases of Tr3 and 7 are connected to set voltage V1 and V3 each. When input voltage Vi increases to exceed V2, output voltage V0 features the value which is obtained by subtracting the voltage drop amount caused by load resistance 19 from power voltage VCC. When Vi increases furthermore to exceed V1, the constant current caused by Tr8 and 9 features the Schmitt action. As a result, no current flows to Tr10 and 11, and V0 becomes VCC again. At this instant, the differential amplifier circuit has no operation losing the function as the voltage comparator. Under such conditions, Vi reduces down until  it becomes identical to V3. And when Vi becomes less than V3, Tr6 is turned on. As a result,  current I6 and I7 flow again to Tr14 and 15, and accordingly the differential amplifier circuit formed by Tr10 and 11 recovers its function.

Title: Image forming device
Inventor: AKIYAMA SATORU
IPC: H05B3/00
Filed: 1990-02-22
Abstract: PURPOSE:To prevent curling and wrinkling while suppressing over-shoot by carrying out controlling so that the supplying of electric power to a heater after the surface temperature of a heating roller reaches a deciding one is reduced as the surface temperature of the heating roller is lower. CONSTITUTION:A temperature storing means 24 storing the surface temperature of the heating roller 14 when a printing commanding signal is received is provided, and the deciding temperature is set between fixable and standby temperatures on an electric power control means 24. After the surface temperature of the heating roller 14 reaches the deciding one, the electric power control means 24 reduces the electric power supplied to the heater as a temperature stored in the temperature storing means 24 is lowered. Therefore, when the temperature stored at the time of receiving the printing commanding signal is low, a lot of electric power is supplied till the surface temperature reaches the deciding one, so that the supplying of the electric power is reduced after the surface temperature reaches the deciding one and the over-shoot is minimized when the surface temperature reaches the fixing capable temperature. Thus, the curling and wrinkling can be prevented while suppressing the over- shoot.

Title: Fuel control of coal-heavy oil mixed burning boiler
Inventor: ASADA EISUKE
IPC: F23N1/00
Filed: 1980-03-31
Abstract: PURPOSE: To better the following property of the total fuel quantity by changing the flow rate of heavy oil good in responsiveness for scores of seconds during which the quantity of coal can not be followed due to changes in the demand signal caused by an impact load even when coal is mainly controlled.  
     CONSTITUTION: While the fuel control system is settled stably, the heavy oil maintains a reference flow rate predetermined by a setting device 4, where the total signal of the amount of coal and the flow rate of the heavy oil is balanced with respect to the boiler master signal. Under this balanced condition, if the boiler master signal rise corresponding to changes in the load, the output of a subtractor 2 develops a deviation. The deviation signal is sent to a coal proportional integrator 3 while inputted into an adder 5 to increase the set signal of the flow rate of the heavy oil. As the heavy oil system responds quickly while the coal system takes much time to respond, increased flow rate of the heavy oil is fed back to the adder.
