Title: Circuit for substituting line before encoding error for modified huffman code
Inventor: MIHASHI YOSHIYUKI
IPC: H04N1/419
Filed: 1987-11-30
Abstract: PURPOSE:To eliminate a need of an encoding circuit and a decoding circuit to reduce the circuit scale and to shorten the processing time by checking only decoding error in the modified Huffman(MH) code. CONSTITUTION:The MH code whose decoding error should be checked is stored in an input buffer memory 1. First, one-line components of the MH code are decoded by a decoding circuit 2, and the decoding circuit 2 does not output an original image signal but outputs only run lengths to only add white and black run lengths at the time of decoding one-line components of the MH code. when EOT as the delimiter of one line is detected, the totalized run length is compared with the number of picture elements of one line preliminarily set for decoding error check, and decoding error is decided if they do not coincide with each other. When the MH code of decoding error is stored in a line memory 6, the MH code corresponding to the line correctly decoded just before is stored in a line memory 7. Thus, the preceding line substitution processing of decoding error is performed without returning to an original image.

Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To realize the transmitter that materializes radio transmission of data, without losing an operating time and carrying performance of a data terminal while suppressing cost increase in the communication terminal equipment. SOLUTION: By a module built in a data terminal equipment, such as a communication terminal equipment and a computer making communication with a base station, by using the multi-carrier TDMA-TDD system, a very weak radio wave having the same frequency as a radio wave frequency used for communication with the base station is used for a timing (slot), when no communication is made with the base station is used to make data communication with a data terminal equipment such as a computer apart from the terminal equipment of the module and the data are stored in the communication terminal equipment at once. An electromagnetic wave with a usual output which is not a very weak wave and stipulated by the law is used to make data transmission with the base station for a timing (slot) when communication is to be made with the base station.  Thus, a data terminal equipment is realized, by which radio data transmission requiring much operating time is attained with superior carrying performance, without increasing the cost of the communication terminal equipment making direction communication with the base station.

Filed: 1994-12-08
Abstract: PURPOSE: To enhance the air-tightness in a throughhole by connecting a conductor provided in an inner face of a throughhole of a cover to an external electrode and supplying solder in the throughhole of the cover. CONSTITUTION: A throughhole 17 made to a cover 3 is formed to be conical in which the diameter of the throughhole toward a vibrator 1 is smaller and a conductor 18 in the throughhole 17 made to the cover 3 is connected to each of external electrodes 4, 5.

Furthermore, the lower part of the conductor 18 is spread toward an open ridge of the throughhole 17 at a face of the cover 3 opposite to the vibrator 1. In this state, molten solder is flowed into the throughhole 17 to cover the conductor 18 covering the upper small diametrical part of the throughhole 17 and solidified into solder 22. Since the outer face side of the throughhole 17 is covered by the solder 22 in addition to the conductor 18, the air-tightness is enhanced.

IPC: H03F1/02
Filed: 1989-11-27
Abstract: PURPOSE:To reduce electric power consumption by controlling a variable bias circuit in such a manner as to decrease the bias current flowing in a differential amplifier circuit when the detected potential difference with an analog comparator circuit is below a prescribed value. CONSTITUTION:The potential of the control signal output of the analog comparator circuit 130 is at a high level when the potential difference of the prescribed value Vr or below is generated between a 1st input terminal(a) of the differential amplifier circuit 910 and one end side (load side) of a resistor 120 for current/ voltage conversion (when the differential amplifier circuit 910 terminates the charging and discharging to a liquid crystal display section 86 which is a capacitive load). A transistor T 21 is, therefore, off and a high bias voltage VB is outputted in a variable bias circuit 140 and the bias current flowing in the differential amplifier circuit 910 decreases. Thus, the differential amplifier circuit is so controlled as to minimize the electric power consumption.
