Title: Transistor circuit
Inventor: SHIMIZUME KAZUTOSHI
IPC: H03K19/00
Filed: 2000-11-10
Abstract: PROBLEM TO BE SOLVED: To reduce useless power consumption caused by a leakage current, etc., in a standby mode. SOLUTION: MOS transistors A and B constitute a transistor circuit (inverter here). A MOS transistor D is a MOS transistor for leakage current cutoff, whose channel is longer than those of the MOS transistors A and B, is made to be conductive only when the circuit is made to operate by the action of an enable terminal (Enable) and is made to be nonconductive to interrupt the leakage current when the circuit is made to be in a standby mode. A MOS transistor C does not affect the circuit when the circuit is made to operate, but suppresses the useless transistor through-current of the standby type circuit of a post stage, which is conventionally caused by midpoint potential in a standby mode by making the potential (not midpoint potential) of an output terminal (Output) to be high or low potential only when the circuit is made to be in the standby mode.

Abstract: PROBLEM TO BE SOLVED: To process images in more finely split frequency bands by obtaining band limiting image signals band-split into finer frequency bands. SOLUTION: A blurred image signal forming means 1 subjects an original image signal Sorg of a square pixel arrangement to an interpolation process (a) which is a squaring and dicing reducing process to obtain a reduced image signal S1, which is then subjected to an interpolation process c which is a dicing and squaring reducing process to obtain a reduced image signal S2. These processes are repeated to obtain a plurality of reduced image signals Sk, each of which is then interpolated and enlarged to the same size as the original image to obtain blurred image signals Susk. The values of differences between adjacent blurred image signals Susk and between the original image signal Sorg and the blurred image signal Sus1 are used as band limiting image signals.  At least one of the band limiting image signals is subjected to a conversion process and the converted band limiting image signals are integrated to produce an integrated signal. The integrated signal is multiplied by a predetermined accentuation coefficient and added to the original image signal Sorg, whereby a processed image signal Sproc wherein the high frequency components of the original image are accentuated is obtained.

Title: Computer system
Inventor: YONEDA TAKASHI
IPC: G06F11/14
Filed: 2000-12-11
Abstract: PROBLEM TO BE SOLVED: To safely operate a computer system by a correctly read program even when the program inside a ROM is erroneously read. SOLUTION: A latch circuit 3 latches the program which is read from the ROM 2. Even when the program B is erroneously read from the ROM 2 as a program C, a CPU 1 outputs an access signal to the ROM 2 again and reads the same program B from the ROM 2. Since the program B is compared with the program C of the latch circuit 3 by a coincidence detecting circuit 4 and is not coincident, the CPU 1 outputs the access signal again. As a result, the program B compared with the program B of the latch circuit 3 by the coincidence detecting circuit 4 on the assumption that the ROM 2 correctly outputs the program B, the programs are coincident so that the CPU 1 regards the program B as the correctly read one and performs the instruction.
