Filed: 1991-07-31
Abstract: PURPOSE:To prevent wire-tapping and robbery including a software by controlling the turn-on of one part or the entire parts of a system power source when specified code information for the system power source turn-on control is inputted. CONSTITUTION:In the control processing of robbery-proof at a power source control processor 2, the contents of a C flag showing the setting of a robbery- proof function received from a CPU in the set processing routines of various flags are stored in an inside RAM 5, in the case of turning on the system power source, it is judged whether a power on key code is inputted from a ten key pad 41 or not and when the power on key code is inputted, a P flag showing the presence/absence of the input is turned on. When the P flag is turned on, it is judged whether the inputted power on key code is coincident with a set power on key code or not, when they are coincident, the key lock of power on (to turn on the system power source) is canceled, and a power on processing with the on operation of a power supply switch 6 is enabled for the first time.

Title: Recovery processing system for duplex volume
Inventor: SAITO YOSHIMASA
IPC: G11B20/10
Filed: 1986-09-12
Abstract: PURPOSE:To eliminate the needs for discriminating a copied area and a non- copied area by executing a preformat processing in which the physical record form of a copy volume is matched to that of a copy volume, permitting a copy processing and a general input output processing to uniformly access to both volumes, and alternately executing them. CONSTITUTION:Before the copy processing 4 starts, the preformat processing 3 is executed in which the physical record form of the copied volume is matched to that of the copy volume. To put it concretely, the content of a volume 1a in an 'ONDUAL' state is copied to a volume 1b in the 'NEUTRAL' state as it is. Since data of the same record form are written in both volumes, updated data by a general input/output processing is written in the same addresses of both volumes in the copied area, and in the non-copied area, same data are already written in both volumes. Thus, the discrimination of the copied area and the non-copied area is eliminated in the recovery processing of a duplex volume.

Then the signal inputted from the branching terminal 3 is transmitted in a direction opposite to the said direction and outputted uniformly to the input terminal 1 and the output terminal 2. Further, in inserting the choke coil L between the coupling point between the input terminal 1 and the output terminal 2 and the branching terminal 3, the terminals are short-circuited in terms of low frequency. Thus, in sending power at DC or low frequencies, the power is supplied from any terminal and received from any terminal.
