Title: Method and equipment for packet data communication
Inventor: FUREDORITSUKU HAIMAN
IPC: H04L12/56
Filed: 1994-04-07
Abstract: PURPOSE: To provide a system and a method for transmitting packet data for linking a remote data-possessing unit with a central computer. CONSTITUTION: A data packet is sent from a remote unit(RU) 15 through an RF link to intermediate base stations(BS) 12-14 and sent from these BS through a serial link 11 to a central computer 10. The RF link uses a frequency-hopping transmission method. The RU 15 and the BS 12-14 are synchronized with the repeated pseudo-random sequence of frequency in bands (902 to 928 MHz) allowed for this type transmission. The RU 15 starts an exchange and performs reception from the BSs 12-14, only during a strict time window continued for that transmission. The BSs 12-14 cannot start communication to the RU 15 but can only send data to the RU 15 as one part of the exchange. Answers from the BSs 12-14 to the RU 15 include synchronization information for maintaining connectability with the pseudo-random sequence.

IPC: H03K5/003
Filed: 1981-05-07
Abstract: PURPOSE:To eliminate variance in shift voltage by providing feedback to a differential amplifier by a transistor (TR) having the same polarity with an output TR. CONSTITUTION:The collector of one TRQ2 constituting a differential amplifier is fed back to the base of the TRQ2 through TRs Q5 and Q6. Consequently, the base potential of a TRQ1 is equal to that of the TRQ2. An output TRQ12 and the TRQ6 have the same polarity and are manufactured at the same time, so their base-emitter voltages are equal to each other and there is no variance in output voltage. In addition, a shift voltage is determined by resistances R11 and R12.

Abstract: PURPOSE:To store only necessary information and to utilize a storage area effectively, by opening a picture fetch gate when there are a specific number of white bits present during one scan, and writing a picture at the circumference of the front edge of a form in a picture memory. CONSTITUTION:When a scanner 11 makes a one-bit scan on a form by every clock of a clock generator 12, the output of the scanner 11 is sent to the writing circuit 16 of a picture memory and written in the picture memory 17 under the control of a gate signal from a counter 14. Namely, the counter 14 does not operate for the starting black ground and the writing circuit 16 inhibits writing to the picture memory 17. Once the front edge of the form is detected, the counter 14 starts counting to invert the gate signal when attaining to the specific number of bits, and the writing circuit 16 operates to send the output of the scanner 11 directly to the writing circuit 16 thereafter. At the same time, the output of a gate circuit is inverted to a low level to turn off a gate circuit 13 and the counter 14.

Filed: 1987-03-24
Abstract: PURPOSE:To obtain an operable differential amplifier even the threshold voltage of an FET is scattered by providing third and fourth FETs, which have respectively a serial resistance at a source side and in which a resistance edge is connected to a gate, between respective drains of first and second FETs and a first power source. CONSTITUTION:To the source side of FETs 3 and 4 for a load, serial resistances 7 and 8 are respectively connected and for respective gates, a bias is added from these resistance edges. When a current to flow at an FET is IDSS and the resistance of the serial connection to a source is RS, a gate bias is a potential lower than the potential of a source only by IDSSXRS. Consequently, the operable threshold voltage of the FET can be obtained from -IDSSXRS up to zero. According to the constitution, even when variance exists at the threshold voltage of the FET, the differential amplifier is constituted and can be sufficiently operated with the wide scope.

Abstract: PROBLEM TO BE SOLVED: To enhance the response to transition and to return from a panning operation. SOLUTION: A shake proof control circuit 22 calculates an angular displacement θ from an angular velocity sensed by angular velocity sensors 18a, 18b and calculates a corresponding shake correction amount based on a focal distance (f) and the angular displacement θ.
