Title: Telephone set
Inventor: NISHIKAWA SHIGERU
IPC: H04M1/00
Filed: 1987-10-01
Abstract: PURPOSE:To attain the holding release request from held side by providing comparing whether a reception signal level is a threshold level or over or not and a means informing the detection of a threshold level or over. CONSTITUTION:When a holding switch 11 is turned on, a control circuit 4 controls a speech circuit 3 to disconnect the line 2 from handsets 7, 8 and a speaker 9, and to hold the DC loop to the line 2. Then a holding tone sending circuit 10 is energized to send a holding tone to the line 2. Thus, the holding tone is sent to the held side. When the switch 11 is turned off, the talking enable state is restored. On the other hand, when a comparator 12 detects that the reception signal level is larger than the threshold level, the circuit 4 energizes a specific signal tone sending circuit 13 to output a specific signal tone from the speaker 9 and the presence of holding release request is informed from the held side. Thus, the sending of the holding release request is attained from the held side.

Title: Terminal equipment for polling system
Inventor: MIURA OSAMU
IPC: H04L12/44
Filed: 1991-09-25
Abstract: PURPOSE:To allow much more terminals to be connected to a center by reducing leakage of a spurious wave from the terminals so as to suppress a noise reaching the center. CONSTITUTION:This invention relates to a terminal for a polling system connecting to 2-way transmission lines formed in trees starting from a center 1 as a stem. An urging signal from the center 1 is sequentially sent to each of terminals 2i (i=1, 2,...). A demodulation circuit 6 of each terminal receives and detects the urging signal and gives it to a control circuit 7. The control circuit 7 detects its own terminal number to turn on a power supply switch circuit 10, which supplies an operating power supply to a modulation circuit 11 and turns on a carrier control circuit 12 after lapse of a prescribed time from that point of time and applies a replay signal to a modulation circuit 11, from which a modulation carrier is sent. After the application of the reply signal is finished, the control circuit 7 turns off the carrier control circuit 12 to stop the carrier transmission and turns off the power supply switch circuit 10 succeedingly.

Title: Cordless telephone set
Inventor: YAJIMA MIKIO
IPC: H04W76/02
Filed: 1993-10-01
Abstract: PURPOSE:To answer a telephone call even from a slave set which can not be changed to a speech channel as well at the time of call from a master unit by switching the reception channel of the master unit from the speech channel to a control channel during the transmission of a ringer request signal to the slave set. CONSTITUTION:At the time of reaching the ringing request timing of a slave set 3, a control circuit decides whether or not the slave set 3 is normally shifted to the speech channel. During the term of the ringing request timing to the slave set 3, the reception channel of the master unit is switched from the speech channel to the control channel, and a call originating request signal from the hand set 3 is received and waited on the control channel. When the speech button of the hand set 3 is pressed for responding to the originated telephone call, a radio path between the slave set 3 and the master unit is closed, a speech path is formed by connecting the slave set 3 and the master unit through a radio path of the designated speech channel to form a speech path, and a speech with an opposite party is enabled. Thus, at the time of calling from the master unit, even the hand set which can not shift to the speech channel can respond to the telephone call as well.

IPC: G06F17/15
Filed: 1986-10-16
Abstract: PURPOSE:To shorten the detection time of a correlation peak value by bringing binary signals of two systems to a correlation processing by using a hard circuit containing two pieces of shift registers. CONSTITUTION:A variable clock generator 10 generates a clock signal of some frequency and drives the first and the second shift registers 11, 12.

The coincidence discriminating part 13 discriminates a coincidence of the data contents between the respective data, and the number of times of its coincidence is counted by a counter group 14 at every bit. In this way, by a counting operation of this counter group 14, a coincidence frequency distribution is obtained, and also, from this coincidence frequency distribution, a correlation peak can be detected.

Title: Superconducting coil
Inventor: URATA MASAMI
IPC: H01F6/06
Filed: 1985-11-06
Abstract: PURPOSE:To increase the effective inner diameter of a superconducting coil by winding a superconducting lead by applying a tension which is large at the inside of the coil and small at the outside of the coil to the lead at winding time to reduce the thickness of a coil spool. CONSTITUTION:When a winding tension is varied according to the position of a layer so as to be strong at the inner layer side and weak at the outer layer side, the radial compressing force 2 applied to a winding blank becomes strong at the inner layer side and weak at the outer layer side. Accordingly, when the compressing force of each layer in case of applying an electromagnetic force generated by the energization becomes a predetermined value or higher, the wire blanks 3 or the blank 3 and the spool 1 are fixed with a predetermined value or larger compressing force. Accordingly, the blank does not move radially nor move axially by a stationary frictional force to eliminate a quench due to the movement of the blank. Thus, the compressing force applied to the coil spool 1 is reduced smaller than that of a coil wound in all layers by the tension of the innermost layer to reduce the thickness of the spool, thereby increasing the effective inner diameter.
