Title: Z butter system for graphic processor
Inventor: HOSOYA KENICHI
IPC: G06T15/40
Filed: 1991-06-17
Abstract: PURPOSE:To shorten the plotting time for the whole screen by controlling whether a frame buffer part and a Z buffer part are updated or not, without reading out a Z value from the Z buffer part. CONSTITUTION:A Z buffer control part 13 writes a Z value of a given coordinate in a register for constituting Z value storage parts 14, 15. Subsequently, the Z value written in the Z value storage parts 14, 15, and a value written in a register of the front Z value storage part 16 are compared by a comparator of a Z value comparison control part 17, and which Z value is the largest is decided. In the case the value of the Z value storage parts 14, 15 is larger than the front Z value storage part 16, a given straight line is not subjected to hidden-line erasure since it is in the front. In this case, since it is in front of any value stored in a Z buffer 12, data of the Z buffer 12 and a frame buffer 11 are updated with regard to an address in which this straight line is plotted. In this case, since it becomes unnecessary to read out the value of the Z buffer 12, the read-out time is not required.

Title: Base circuit of transistor
Inventor: IWAMOTO HIDEO
IPC: H03F1/52
Filed: 1982-08-18
Abstract: PURPOSE:To protect a transistor (TR) from a large displacement current, by operating a switching device so as to short-circuit the base and emitter, when a voltage change detector detects the voltage change applied between the collector and emitter of the TR. CONSTITUTION:A base drive device 2 drives a TR1. The voltage change applied to the collector and emitter of the TR1 is detected with a differentiating circuit comprising resistors R10, R13 and a capacitor C11. A detected current flowing to the differentiating circuit charges up the C11 and the charging current is branched into the R13 and the base of a TR12. Thus, the TR12 is turned on and the base and emitter of the TR1 is short-circuited. The displacement current because of the voltage change between the emitter and collector of the TR1 is led to the base, allowing to prevent the destruction of the TR1.
