IPC: H03M7/12
Filed: 1994-11-08
Abstract: PURPOSE: To provide a binary/decimal converting circuit which can convert arbitrary binary data with the large number of bits and can be integrated into a PLD or a gate array. CONSTITUTION: The binary data with the prescribed number of bits to be converted are initially set to a shift register 1, afterwards, the operated binary data are repeatedly inputted and finally, converted data composed of code bits are formed in the format of BCD. The number of times of block operation is equivalent to the number of bits of the shift register 1. A constant generating circuit 2 generates the constant of addition/subtraction at every time of operation. An adder/subtraction circuit 3 performs addition or subtraction successively designated from a least significant bit. An arithmetic and control circuit 4 inputs the arithmetic result to the shift register 1 in the order of addressing to one bit while controlling the constant generating circuit 2 and the adder/ subtraction circuit 3.  In that case, the code bit is inputted after being inverted and corresponding to the logic value of that code bit, it is judged whether the next operation is addition or subtraction.

IPC: H04W68/00
Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To control incoming call sound volume and incoming call pattern from a caller as well by providing a means for changing the incoming call sound volume based on a control signal transmitted from the side of call origination. SOLUTION: A call originating request is transmitted from the side of call origination to a base station and the report of call incoming is transmitted through a telephone network and the base station to portable radio equipment 10 on the side of call termination. On the other hand, a signal showing a report under calling is transmitted from the portable radio equipment 10 on the side of call termination to the base station until a callee operates the portable radio equipment 10. When the caller operates an operating part 44 to set the incoming call sound volume, incoming call sound pattern and maximum incoming call sound volume before a party on the side of call termination answers, a control part 40 converts these set values to a control signal and a radio part 20 transmits this signal to the base station.  The base station reports the control signal contained in this signal to the side of call termination. When this signal is judged as a signal for incoming call sound volume control on the side of call termination, the control part 40 compares it with the maximum ring back tone volume stored in a memory 32 and when it is lower than that volume, a ringer 50 is rung with the designated volume.

IPC: G02B7/28
Filed: 1998-10-21
Abstract: PROBLEM TO BE SOLVED: To highly accurately and quickly retrieve and decide an optimum focal position regardless of the profile shape of a featured value for a processing object. SOLUTION: In this parameter deciding method, an evaluated value profile for a very small part is prepared (S11), and the theoretical value Δr of a sampling interval applied to coarse adjustment is calculated by an analytical technique (S12). Next, the existence of a maximum value PL is discriminated from the evaluated value profile (S13), and in the case that the maximum value PL exists, the sampling interval Δr' is set based on a threshold TH which is equal to or larger than the maximum value (S14). Next, the theoretical value Δr and the corrected value Δr' of the sampling interval are compared, and in the case that the corrected value Δr' is smaller, the coarse adjustment is executed again by applying the corrected value Δr' (S16).
