IPC: H03M7/38
Filed: 1993-10-20
Abstract: PURPOSE:To make a circuit scale small, and also, to suppress an output delay of data by constituting the ADRC encoder without using a multiplier. CONSTITUTION:In the case of the number (N) of quantizing bits = 3, the ADRC encoder 10 decides directly to which numerical value obtained by dividing a dynamic range(DR) into seven equal parts the element data is the nearest by a technique of sorting without using a multiplier, classifies the element data into '0'-7. That is, the DR is inputted to a ROM 14 from a terminal 12, and the ROM 14 gives data (DR/14) corresponding to the inputted DR to a multiple circuit 16. The multiple circuit 16 allows the data to be subjected to '1'-13 folds (odd number folds). Subsequently, to which range prescribed by an output from the multiple circuit 16 the element data Lt-MIN inputted from a terminal 40 belongs is decided by using comparators 42-46 and selectors 50-56. The respective outputs of the comparators 42-46 are obtained as a value Q of three bits as they are.

Abstract: PURPOSE: To provide a simple telephone system with high secrecy by extracting the individual information of a visitor from pictures by an individual information extraction device and performing dialling and the display of telephone number information corresponding to the extracted individual information. CONSTITUTION: When the visitor lets a scanner read a business card, a picture input device 1 reads the business card as picture information and the inputted pictures are transmitted to the individual information extraction device 2 and a picture storage device 9.

Thus, the individual information such as a company name, a department name, an individual name and a telephone number is extracted and displayed at a display part 4. When the character recognition is inaccurate and when the visitor discovers errors in the displayed individual information, correct characters and numerals are inputted by using a correction part 5 and the individual information is corrected.  Thus, the accurate individual information of the visitor is obtained and transmitted to a controller 7. Then, the controller 7 displays the telephone number of a range set beforehand at a telephone book display device 8.

Title: Ratchet wrench
Inventor: KAMIYA TADASHI
IPC: B25B21/00
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of overshoot and to prevent the occurrence of unintended inversion switching. SOLUTION: In a ratchet wrench having a blade member 44 and the blade member 44 energized by a spring 58 through a push pin 56, an elastic member 66 formed of a material, such as rubber, having elasticity is incorporated in an internal space in the axial direction of the spring 58. This constitution increases a press force in a direction in which engagement between the claw 46 of a blade member 44 and the internal tooth gear 30 of an oscillation body 26 is held. Thus, when a force is exerted on the blade member 44 in a direction in which engagement between the claw 46 of the blade member 44 and the internal tooth gear 30 of the oscillation body 26 is released, the repulsion force of the spring 58 and the repulsion force of the elastic member 66 are exerted and the elastic member 66 is worked as a stopper, overshoot is prevented from occurring.  Further, since the holding force of a switching member 52 on a shank 36 is increased by the spring 58 and the elastic member 66, unintended reversion switching of a switching member 52 is prevented from occurring.

Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To make all parts into an IC and to surely hold the peak of the level of an input signal to always perform the stable operation even in the case that the input signal is not inputted for a set period or longer or its level is varied to the low level. SOLUTION: When an input signal 100 is higher than a hold voltage PDP of a capacitor 36, a sequencer 58 outputs a clock SCK1 to a leak circuit 34 to interruptedly hold the peak of the input signal 100 by the capacitor 36. When the input signal 100 is lower than the voltage PDP, the sequencer outputs a clock RCK1 to the leak circuit 34 to interruptedly discharge the hold voltage of the capacitor 36 up to a set voltage, and the capacity of the capacitor 36 is reduced. If a signal SEH doesn't go to the high level for a set time or longer, the sequencer 58 outputs the signal SCK1 at a prescribed timing to certainly hold the peak of the input signal 100 in the capacitor 36.
