Title: Sheet clamp
Inventor: MORISAWA MASAHARU
IPC: B42F15/00
Filed: 1989-05-24
Abstract: PURPOSE:To repeatedly use a release sheet without damaging or breaking a clamp main body when the sheet is repeelled by applying synthetic paper to the back of the clamp main body made of expandable resin via an adhesive and applying a release sheet to the back of the synthetic paper via a releasable adhesive. CONSTITUTION:A permanent adhesive 2 is applied to the back of a plate body 1' made of expandable resin such as urethane, and synthetic paper 3 made of chloroethylene, etc., sticks thereto. A releasable adhesive 4 is put to the synthetic paper 3 as less adhesive glue, and a preservation release sheet 5 is applied thereto. To use the release sheet, the release sheet 5 is peeled, and a part a' of the rear face is applied to part of a sheet B releasably, and simulta neously the other part a'' of the rear face is applied to a wall surface C releasably. To repeel the sheet, the synthetic paper 3 acts to strengthen the adhesion, and the adhesive surface of the releasable adhesive 4 is peeled against tensile force between the releasable adhesive 4 and the sheet B and tensile force between the releasable adhesive 4 and the wall surface C. At this time, a clamp main body 1' is supported by the synthetic paper 3, thereby preventing damage including rupture.

Title: Residual capacity meter of battery
Inventor: TANJO TAKEJI
IPC: B60L50/16
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To detect and display the exact residual capacity of a battery regardless of the occurrence of deterioration. SOLUTION: A state of charge SOC3, where a decline rate of the possible output power of a battery exceeds a prescribed value, is supposed as SOC 100%, and a state of charge SOC4, where the possible input power is equal to the possible output power, is supposed as SOC 0% as well. SOC of the battery is obtained based on an open terminal voltage at the time when SOC of the battery is 100%, an open terminal voltage at the time when SOC is 0% and an open terminal voltage of the battery detected by a voltage detector, and then a residual capacity is displayed by the SOC.  Therefore, the capacity of a new battery and the capacity of a deteriorated battery become apparently nearly equal, so the apparent capacity does not reduce even when the battery is deteriorated, and SOC of the battery can be easily detected by the open terminal voltage, and besides, even when the battery is deteriorated, an actual residual capacity does not become smaller than the residual capacity displayed value.

IPC: G06K9/20
Filed: 1992-05-26
Abstract: PURPOSE:To enable efficient work without necessity for confirming the direction of read original images on a display in the case of inputting images. CONSTITUTION:First of all, a counter 4 is initialized to '1' and counters 5 and 6 are initialized to '0' in a step 21. In a step 22, characters are segmented from original images and in a step 23, the segmented characters are recognized. When the recognition is successful in a step 24, the counter 5 is incremented by '+1' in a step 25. When the recognition is unsuccessful, the segmented characters are rotated at 180 deg. in a step 26 and concerning these characters rotated at 180 deg., they are recognized in a step 27. When the recognition is successful in a step 28, the counter 6 is incremented by '+1' in a step 29. When these processes are completed, '1' is added to the counter 4 in a step 31. The above- mentioned processes are repeated six times and finally, the direction getting the more number of times for performing the recognition successfully is defined as the correct direction in a step 32. When the direction is reversed, the original images are rotated at 180 deg. in a step 33.

CONSTITUTION:A digital phase comparator 2 outputs the digital phase difference signal corresponding to the phase difference of both a reference clock signal inputted to an input terminal 1 and an output clock signal of a digital control oscillator 6. An arithmetic unit 3 receives the digital phase difference signal, and outputs a 1st digital control signal proportional to the phase difference from a proportionality control term 31. By adding the same digital phase difference signal to an integral control term 32, an integrated 2nd digital control signal integrated after multiplying a very small coefficient by a digital phase difference signal is outputted. a second digital control signal is stored in a nonvolatile memory 4. An adder 5 adds the output from the nonvolatile memory 4 to the 1st digital control signal from the arithmetic unit 3, then outputs a control signal to the digital control oscillator 6.
