Title: Digital signal recorder and digital signal reproducing device
Inventor: FUJIWARA YUJI
IPC: G11B20/12
Filed: 1993-11-17
Abstract: PURPOSE:To record data while reducing additional information effectively and to reproduce a video signal efficiently by recording frame information of data in a SYNC block to a predetermined location in the SYNC block in a 2nd group track. CONSTITUTION:A memory write control circuit 4 stores data coded in the unit of SYNC blocks SnB to memories 56. Various additional information is recorded at a predetermined position in the SnB and data of each DCT block are recorded in order from a lower frequency component. Thus, the data are sequentially recorded to each track of the memory 5. The additional information of higher frequency data of a 1st frame not written in the memory 5 is written to a predetermined position and the higher frequency data are written respectively to the data recording area of the memory 6 respectively. When a video signal of a 2nd frame is written in succession to the 1st frame, a pointer starting the input of the 2nd frame is recorded to a final byte and written in the remaining space. When the data are written from the start of the data recording area, frame information representing the 2nd frame is written and data of the 2nd frame are written.

Abstract: PURPOSE:To obtain excellent writing characteristics and reading characteristics and, further, improve the stability of information holding and reproduce durability by a method wherein (n) layers (wherein (n) denotes an even number not smaller than 3) of magnetic layers composed of magnetic thin films are laminated on a substrate with mutual exchange couplings and the respective magnetic layers satisfy specific conditions. CONSTITUTION:If the Curie point of an (i)th magnetic layer (wherein (i) denotes a natural number not larger than (n)) is denoted by Tc1 and it is defined that Tcn+1 = ambient temperature, for any natural number (m) which is not larger than (n-1)/2, the vertical magnetic anisotropy (Ku) and the saturated magnetization (Ms) of a (2m+1)th magnetic layer at a room temperature are 7X10<5> erg/cm<3> or larger and 300 emu/cm<3> or smaller respectively and Tc2m+1>=Tc1>=Tc2m and Tc2m>=Tc2(m+1). The magnetization of the (2m+1)th magnetic layer is so oriented as to provide the stable state of a coupling state produced by an exchange interaction with a (2m-1)th magnetic layer when the temperature of a (2m)th magnetic layer drops to its Curie point Tc2m or lower.

Title: Switchboard terminal
Inventor: SAKAI NOBUYUKI
IPC: H04M3/42
Filed: 1988-12-12
Abstract: PURPOSE:To easily comply with various requests given from the switchboard terminals (operators) and to ensure the exchange services by registering the automatic operation information showing whether various exchange services should be automatically operated or not. CONSTITUTION:When an incoming signal showing an incoming state is received by a switchboard terminal 1 from an electronic exchange 4, an operator usually operates a key for an answer via a keyboard 2 to produce an answer event. In this case, however, a connection control part 15 refers to the automatic operation information stored in a memory part 12 at the terminal 1. Then a signal generating part 14 produces an answer signal equivalent to a keyboard operation of the operator with the instruction of the part 15 since the automatic operation information ('1') is registered in a memory part 121 in response to the answer of the operator. Then the answer signal is inputted to an input/ output signal process part 11. Thus it is possible to transmit a signal to the exchange 4 in response to the answer event without requiring the actual keyboard operations of the operator.
