Title: Amplifier circuit for telephone communication
Inventor: OKA TSUNEAKI
IPC: H04M1/60
Filed: 1985-09-02
Abstract: PURPOSE:To compensate level reduction at a high frequency band of a reception signal at increase in the line loss by varying a variable impedance in response to the detection output of a line current detection circuit so as to change the amplification factor at a specific frequency band of a reception amplifier circuit. CONSTITUTION:A detection circuit 6 detecting a line current is provided and variable impedance circuits 38, 48 are provided at least to one of a transmission amplifier circuit 30 and a reception amplifier circuit 40. The impedance of the variable impedance circuits 38, 48 is varied in response to the detection output of the circuit 6 to change the amplification factor at a specific frequency band of the circuit 40 to compensate the level reduction of the reception signal at a high frequency band when line loss is increased. Thus, the increase in the loss at a high frequency band when the line length is long is reduced and the long distance communication with high quality is attained without causing the decrease in the articulation of the talking voice and the increase in the signal error.

IPC: H04M3/42
Filed: 1988-08-04
Abstract: PURPOSE:To decrease the waste of a talking charge and to save the wait time by allowing a central controller to control the system such that a message representing enable recording is sent from a message transmission circuit to a trunk line and a message from the trunk line is recorded by a message recording circuit at the holding state of an extension telephone set. CONSTITUTION:The central controller 6 connects a message transmission circuit 9 to the trunk line 1 via a main switch 3 at the holding state of the extension telephone set 5 to send a message representing the reception of the message recording to the trunk line 1. Then the message recording circuit 12 is connected to the trunk line 1 via the main switch 3 to record the message from the trunk line 1.

Title: Optical fiber terminator
Inventor: FUJII YOJI
IPC: G02B6/00
Filed: 1990-07-24
Abstract: PURPOSE:To obtain high return loss by approximating the refractive indexes of adhesives for adhering the other end of a small optical fiber piece to dichroic polarizers to the refractive index of the core of the small optical fiber piece. CONSTITUTION:One end of the small optical fiber piece 1 is terminated by an optical connector plug 7 and at least two dichroic polarizers 3a and 3b whose azimuths cross each other at right angles are laminated and adhered to the other end of the small optical fiber piece 1; and the refractive index of adhesives 4a and 4b for adhering the dichroic polarizers 3a and 3b to the other end of the small optical fiber piece 1 are close to the refractive index of the core of the small optical fiber piece 1. Consequently, light which is guided out of the small optical fiber piece 1 is absorbed by the two dichroic polarizers 3a and 3b whose azimuths cross each other at right angles, so this light is never coupled with the small optical fiber piece 1 again and does not become waveguide light, and the high return loss is realized.

IPC: H04N7/173
Filed: 1987-08-05
Abstract: PURPOSE:To improve the quality of information by changing-over a picture and sound switching circuit with receiving sound end detecting information in a center side and sending the next picture data with a picture transmittable condition. CONSTITUTION:When A sound information are ended, the silence of a constant period is detected by a silence detector 18 to have a threshold which is enough smaller than a sound and enough larger than line noise and it is decided as A sound information ending and transmitted to a control device 1 as a sound ending code. The control device 1 changes-over a picture and sound changing- over switch 10 to a high-speed MODEM 6 side and executes the preparation of the next receiving of picture information. The sound ending code is sent to the control device 1 of the center side by a route 1. The control device 1 recognizes that a terminal side decides the A sound information ending, changes-over a picture and sound changing-over switch 17 to a high-speed MO DEM 14 side and sends the next B screen information to the terminal side by a route 2. Then, an operator can listen to a B sound simultaneously with a B picture in the same way as the case of an A picture. Thus, picture information and sound information can be automatically received continuously.
