IPC: H03H19/00
Filed: 1981-06-12
Abstract: PURPOSE:To obtain a signal voltage dividing circuit having high accuracy, by connecting the 1st and 2nd switches which are formed by combining a switch having the 1st and 2nd contacts and the capacitance and extracting the voltage of the joint by holding the sample. CONSTITUTION:The other end of each of the capacitances 8 and 15 having an earthed end respectively is switched to the 1st and 2nd contact 18 or 19 and 20 or 21 by means of the switches 7 and 14. The contact 18 is used for a signal input, and the contact 21 is earthed. At the same time, a switch 25 is connected to the joint between the contacts 19 and 20. The switching between the contacts 26 and 27 is controlled by a clock signal 9 so that the switch 25 is connected to a terminal 14 when the switches 7 and 14 are connected to the contacts 19 and 20, respectively. Then the voltage of the terminal 14 is sampled by the switch 25 and held at a holding capacitance 17 to reduce the effect to the signal emerging at a terminal 28 although the stress capacitances 22 and 23 of the switches 7 and 14 exist.

IPC: C23F3/00
Filed: 1983-05-23
Abstract: PURPOSE:To generate high precision and high quality finish on a surface by placing a workpiece in etching solution so as to face to a flat and convex lens, and by polishing the surface by radiating argon laser beams onto the surface while making relative movement between the workpiece and the lens. CONSTITUTION:A workpiece (aluminium alloy) 12 fixed to the surface plate is placed in the vessel 15 containing solution 14 for etching the workpiece so as to face to the flat face of a flat and convex lens 13 with a minute clearance (e.g. h=20-30mum). The surface of the workpiece 12 is polished by radiating argon laser beams 16 on the surface of the workpiece 12 through the flat and convex lens 13, while moving the surface of workpiece 12 relatively to the surface of the lens 13 by a travel table 17. The radiation of the laser beam 16 promotes etching on the workpiece 12 to dissolve the surface layer thereof. At this moment, large shearing stress is applied by fluid friction to the protrusions of the workpiece 12, so that such protrusions are removed in its quantity more than their surroundings, and the surface precision of the workpiece 12 is corrected to copy the flat face of the lens 13, whereby a high precision flat surface is generated.

Title: Start-up circuit for sea water battery
Inventor: OKADA CHIKASATO
IPC: H01M10/44
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To bring the operation starting time forward after putting a battery into the water by providing a short-circuit for the output of a battery and a circuit for opening the short-circuit when the current value exceeds the predetermined value. SOLUTION: When a battery 1 is putted into the sea water, the sea water intrudes into the battery 1 so as to generate the voltage. Since a (+) terminal and a (-) terminal of the battery 1 form a short-circuit with a fuse 3, the current I1 is made to flow from the (+) terminal to the (-) terminal, and voltage is not applied to a load circuit 2. Internal resistance RB inside of the battery 1 is unstable at the initial time and the current I1 is small, but when the sea water sufficiently intrude and the battery 1 is heated by the current I1 , the internal resistance RB is reduced and stabilized, and the current I1 becomes large. When the current I1 exceeds the rated current of the fuse 3, the fuse 3 is blown ont and the voltage V is applied to the load circuit 2, and the current I1 is made to flow so as to start the operation of the load circuit 2.  With this structure, the time to be required for reducing and stabilizing the internal resistance of the battery can be shortened.
