Title: Production of calcined powder of starting material for ferrite
Inventor: KUSAKABE NOBUO
IPC: C04B35/622
Filed: 1991-03-26
Abstract: PURPOSE:To produce high-quality calcined powder giving a molded body for a soft ferrite core which does not crack or hardly cracks during concluding firing. CONSTITUTION:When starting material for ferrite is calcined, average cooling rate within the range from the calcining temp. to 300 deg.C is kept at <=20 deg.C/min. Since a molded body of the resulting calcined powder for a soft ferrite core does not crack or hardly cracks during concluding firing, product yield can be enhanced and significant effects are produced with respect to production cost and productivity.

Title: Switching system for common line signal system
Inventor: NAKAGIRI ETSUJI
IPC: H04M7/06
Filed: 1987-03-17
Abstract: PURPOSE:To surely perform the test of a call, by shifting a state to an ordinary call processing state after performing the confirmation of test connection without transmitting and receiving an unrequired signal when a speech line is installed additionally. CONSTITUTION:An opposite station B clears a signal transmitting/receiving state until then by sending a line reset signal (RSC) (a), and its own station A can recognize the state of the opposite station B by receiving a reset confirmation signal (b) from the opposite station B. And a call connecting request from the opposite station B is blocked by sending a close request signal (BLO) (c), and also, it is possible to send a test call connection request signal (g) to the opposite station B. After the BLOc being sent, a close confirmation signal BLAd from the opposite station B is waited, and after the signal being received, a test call is placed. Also, when the RSC is issued prior to the test call, since a line identifying code exists in the RSC and the reset confirmation signal (RLG) is returned from the opposite station B when it is recognized, the acceptance state of the signal of the opposite station can be recognized by the reception of the RLG. In such a way, it is possible to place the test call correctly.

Title: Error rate supervisory system
Inventor: KURIHARA HIROSHI
IPC: H04L12/26
Filed: 1978-05-23
Abstract: PURPOSE: To increase the accuracy for the error rate supervisory circuit by adding the noise component to the base band signal before identification for identification and reproduction and then carrying out the logic calculation between the identified reproduction output and the identified reproduction signal of the main route to obtain the false error signal.  
     CONSTITUTION: For the received 4-phase modulated wave, synchronous detection 16 is given with 90° - phase shift 15 between the 4-multiplied 11 signal and the 4-multiplied carrier obtained from the 4-multiplied wave with deletion of the noise component through LPF12. Thus, the base band convereted noise component is drawn out to be added 20 to the base band signal which is obtained by branching off from the main route and before identification and reproduction. Then identified reproduction 21 is carried out, and logic operation 22 is given between the identified reproduction output and the identified reproduction signal of the main route to obtain the false error signal. In this way, a constant corresponding relation can be kept between the deterioration quantity of the error rate of the supervisory circuit group and the real error rate of the real circuit against the phase fluctuation of the timing signal. As a result, the accuracy can be increased for the error rate supervisory circuit.

Title: Start-stop data multiplexing system
Inventor: NISHIMURA YASUYO
IPC: H04L5/24
Filed: 1989-03-16
Abstract: PURPOSE:To prevent an idle state of a start-stop data by sending a multiplex data with a parallel data from a 2nd conversion section when a start-stop error takes place in the data in the case of serial/parallel conversion to an inputted start-stop data with a 1st conversion section. CONSTITUTION:A start-stop data comprising characters D1-Dn is inputted to serial parallel converters 3, 13 via a terminal 1 and an interface 2. The converter 3 applies serial parallel conversion to each start bit and each stop bit of the start-stop data D1-Dn with an output of an Z-A polarity change detection circuit 7. On the other hand, the converter 13 applies serial parallel conversion to the first start bit of the data with an output of a Z polarity detection circuit 9 detecting the said bit. Thus, if, e. g. a character D2 has a start-stop error, the characters D2, D3 are not converted by the converter 3 but by the converter 13. After a number 2 of the character D2 is stored in a RAM 16 together with the characters D1-Dn, the data is multiplexed and sent.
