Title: Key telephone system
Inventor: IWATA HIDETOSHI
IPC: H04Q3/58
Filed: 1990-09-07
Abstract: PURPOSE:To easily identify whether or not a call comes from a trunk line by ringing each single telephone set with a call signal in the case of the arrival of the call from the trunk line and generating a sound different from the ring tone from a speaker. CONSTITUTION:In the case of the arrival of a call from a trunk line 1, a control circuit 5 starts a 16Hz signal oscillator 3 and an incoming call tone oscillator 4. Since the 16Hz signal oscillator 3 outputs a 16Hz call signal, each single telephone set not hooked off rings and since a tone signal different from the 16Hz signal is outputted from the incoming call tone oscillator 4, a sound different from the ring tone is sounded from a speaker 9. Thus, the arrival of the call from the trunk line 1 is confirmed by each of the single telephone sets 61,..., 6n, and the arrival of the call from the trunk line 1 is identified depending on the sound from the speaker.

Title: Magnetic disk device
Inventor: ASADA HIDEO
IPC: G11B20/12
Filed: 1987-09-21
Abstract: PURPOSE:To correctly read out data from a data track by adding a flag capable of discriminating other records than the final record to the final record of the records to be written in a series of format operations. CONSTITUTION:In a write format of the titled magnetic disk device, a home address exists immediately after an index mark, and a record exists after the home address. A count part of the record consists of a bit of defective information 11, a bit of address information 12, a record number 13, a record length 14 and a final record flag 15. As to the flag 15, [FF] is written in case of the final record, and [00] in case of other records.

Title: Taping device and taping system
Inventor: TASHIRO HIROAKI
IPC: B65H81/04
Filed: 1990-09-07
Abstract: PURPOSE:To mechanize the commencement and termination of taping and automatic supply of a tape by providing a mechanism, which bonds and fixes the head/terminal of a tape to a clamp L coil and cuts the tape end, a mechanism, which automatically supplies the tape, and a mechanism, which tapes both ends of the coil automatically and inclines and rotates the coil. CONSTITUTION:A bonding gun 17 is placed on a cylinder through a mounting base 16. At the time of bonding, the bonding gun 17 shifts in the arrow direction by the working of the cylinder 19. Since the direction of the cut on the circumference provided on a rotation ring 2 is up at this time, the bonding gun 17 does not interfere with the rotation ring 2. In this condition, an adhesive is applied right on a coil strand 1. After application, the bonding gun retreats to the former position by the working of the cylinder 19. By the bonding gun 17 retreating, the tape 4 is prevented from interfering with the bonding gun 17 when it rotates.
