Title: Current mirror circuit
Inventor: TSUCHIYA MITSUHARU
IPC: H03M1/74
Filed: 1989-05-24
Abstract: PURPOSE:To eliminate the influence of the stray capacity of a transistor(TR) and to speed up the operation by connecting a capacitor whose capacity is larger than the floating capacity of the TR between the common base of TRs constituting the current mirror circuit and a power source or the ground. CONSTITUTION:The large capacitor C is connected between the common base CB and power source Ve. Consequently, pulse voltages induced from the respective collectors to the common base CB are divided by the capacitor C connected to the floating capacity Cs. The voltage-divided value is larger and larger as the value of the capacitor C is larger and larger than the floating capacity Cs, and when the capacity of the capacitor is 100 times, unnecessary pulse components generated by this current mirror circuit become 1/100 as large as those of a convertional circuit. Consequently, the influence of the stray capacity Cs of the common base CB is eliminated substantially by connecting the capacitor C. Therefore, even when switches SW1-SWn operate fast, the influence of their pulse voltages is eliminated and the current mirror circuit can operate fast.

Filed: 1993-05-11
Abstract: PURPOSE:To ensure a wide and continuous sound recording region by detecting the gap between recorded regions on a minidisc and sorting the recorded information when the detected gap is larger than a predetermined value thereby eliminating the gap. CONSTITUTION:The UTOC recorded on a minidisc 12 is sorted according to the address of cluster thus preparing a new table. The gap in the table is then searched and when the gap between the regions is equal to or larger than six clusters, the data is read out from the region on the disc 12 until a RAM 3 is filled or up to the end of the region. The data written into the RAM 3 is then rewritten to a new location of the disc 12 thus shifting the region. This constitution eliminates many trash regions generated at the time of edition of the minidisc and ensures a wide and continuous sound recording region thus reducing the impact resistance at the time of sound recording.
