Title: Automatic transmitting and receiving modem
Inventor: TAMURA YU
IPC: H04M11/00
Filed: 1988-09-30
Abstract: PURPOSE:To attain a data communication and a call with one line by providing a controller to control a ringer part, output a ringer signal to a telephone set and connect the telephone set to the line when an identification signal detector detects an identification signal. CONSTITUTION:The handler of a terminal 11 sends a prescribed PB sound from a telephone set 9 to call a telephone set 13 during the data communication. An identification signal detector 3 informes a modem controller 8 of a number corresponding to the PB sound and the controller 8 switches a switching circuit 4 to the side of the telephone set 13 and switches a switching circuit 5 to the side of a ringer part 7. When a handler on the side of a modem 1 responds to this and picks up a receiver, the switching circuit 5 detects this off-hook, informs the controller 8 and the controller 8 switches the switching circuit 5 to the side of a channel 15. Thus, it becomes unnecessary to perform a troublesome operation and the call by the telephone is attained without providing more lines.

IPC: G02B13/18
Filed: 1988-09-30
Abstract: PURPOSE:To make the parallel eccentric driving quantity of a movable lens irrelevant to the value of focal length while maintaining excellent optical performance and to simplify mechanism by using a movable lens group as the lens group of part of the variable magnification optical system and driving the movable lens group eccentrically, and thus correcting the deviation of an image. CONSTITUTION:A 1st group I with positive refracting power and a 2nd group II with negative refracting power are provided and moved as shown by arrows to perform magnification variation from a wide-angle end to a telephoto end. Further, the 1st group I consists of a group 11 with negative refracting power, a diaphragm SP, and a group 12 with positive refracting power. Then a hand shake of a camera and the blurring of a photographed picture caused by the vibration of the variable magnification optical system are corrected by driving the group 12 as the movable lens group eccentrically in parallel at right angles to the optical axis. Focusing, on the other hand, is performed by moving the group 11 which is arranged in front of the diaphragm SP on the optical axis. Consequently, the mechanism is simplified and excellent optical performance is obtained.

IPC: H04L7/08
Filed: 1989-09-22
Abstract: PURPOSE:To prevent an erroneous data from being read in by adopting the constitution such that the data read is stopped when frame synchronization is unlocked and the error data is detected. CONSTITUTION:A data frame synchronization detection circuit 2 detects whether or not frame is out of synchronization and outputs a reset signal to a timer circuit 4 when the frame is out of synchronization unlocked. Moreover, a data error detection circuit 6 judges whether or not a data output of a data read circuit is an erroneous data, and outputs a reset signal to a timer circuit 4 when the data is an erroneous data. The timer circuit 4 is reset by OR between the data frame synchronization detection circuit 2 and the data error detection circuit 6 and resets a start flag detection circuit 3 when a prescribed count is counted afterward. Thus, reading of an erroneous data is evaded.

Title: Frequency conversion circuit
Inventor: AKITANI MAKOTO
IPC: H03D7/00
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To balance an output waveform in spite of an input electric field, using simple circuit constitution. SOLUTION: A bidirectional diode 3 is installed between an RF(radio frequency) input terminal and the base of a local amplifier 2. When the amplitude of an RF input signal 10 is large (when electric field is strong), current flows in the bidirectional diode 3, and a base voltage applied to the local amplifier 2 is changed. Base bias current from a bias supply circuit 4, where the amplification output is set to be input, changes. A matching condition with a matching circuit 5 collapses with the change in bias current, the gain of the local amplifier 2 is reduced and output power is decreased. The frequency conversion gain of a mixer 1 receiving a local wave, whose injection level drops in reduced, and voltage does not reach the saturation voltage of the mixer 1.  Although a strong electric field is inputted, the IF(intermediate frequency) output signal 11 of a balanced output waveform can be obtained from the IF output terminal of the mixer 1.
