Patent JP-S62190976-A (JP)
Title: Automatic focusing device
Inventor: TOYODA HIDEO
IPC: H04N5/232
Filed: 1986-02-18
Abstract: PURPOSE:To drive a motor securely into a focusing state by detecting whether or not a synchronous detection output which becomes a signal for driving the motor is nearly fixed in phase and its amplitude is within a specific range for a certain time, and supplying the synchronous detection output or alternate signal to the motor or varying a loop gain according to the detection result. CONSTITUTION:When a lens 1 comes close to a focusing point and a reference frequency component becomes small, the output amplitude of a synchronous detecting circuit 10 decreases gradually. At this time, if its output level enters the blind sector of the motor 12 and the motor 12 stops, the synchronous detecting circuit 10 outputs a signal which has the same polarity and level continuously. A comparing circuit 13 or 14, therefore, outputs logic 1 continuously according to the polarity. This is detected by a shift register and an AND circuit and sent to a control circuit 19. The control circuit 19 connects a switch 20 to a battery 21 or 22 for a constant time according to whether the detection result is sent out of an AND circuit 17 or 18. Consequently, the values of the batteries 21 and 22 are set larger the blind sector, and then the motor 12 moves in a focusing direction.

Abstract: PURPOSE:To omit the erasion of data by operating a power supply by a spare power source when the power supply from a main power source is stopped, and saving the data to a nonvolatile storage means. CONSTITUTION:When a fault occurs in a main power source device 3, and the power supply to the main body of a computer 1 is stopped, a spare power source device 16 starts the operation, operates the power supply to the main body of the computer 1 instead of the main power source device 1, and at the same time, operates an interruption to a CPU 11. At that time, the CPU 11 recognizes the occurrence of the fault of the power source by this interruption, and saves the data which are difficult to be restored and reactivated once erased among the data in a buffer for a secondary storage device 2 of a main storage part 13, to a nonvolatile memory 15. Then, the main body of the computer 1 stops the operation.

IPC: H01M4/68
Filed: 1986-02-19
Abstract: PURPOSE:To reduce the weight of a whole storage battery without deteriorating the performance thereof, by adding prescribed short fibers or whiskers to lead or a lead alloy to make an electrode of a fiber-reinforced composite material having the lead or lead alloy as the matrix thereof. CONSTITUTION:Reinforcing fibers made of potassium titanate whiskers or short fibers of alumina are preparatorily formed as a column. The formed fibers are disposed together with lead in a die made of graphite. The die is then set is a hot-press and heated at a prescribed temperature for a prescribed time under vacuum suction. The formed fibers and the lead, which is to become a matrix, are then pressed at the pressure of 200kg/cm<2> to impregnate the molten lead into the preparatorily formed piece of the fibers to reinforce the lead by the potassium titanate whiskers or the fibers of alumina. A fiber- reinforced material is thus manufactured to make an electrode. This results in reducing the weight of a whole storage battery without deteriorating the electric conductivity, durability and corrosion resistance thereof.
