Patent number: 6005422Abstract: A semiconductor integrated circuit and a method for reducing the consumed power are provided. A comparator outputs bits having the same level, which correspond to each other, of a last input stored in a register and a current input that acts as an input signal. A zero counter counts the number of the bits having the same level output from the comparator. If the number of the bits having the same level is smaller than a predetermined number, the current input is not similar to the last input. Consequently, an instruction is given to a flip-flop to invert the current input. The inverted current input becomes similar to the last input. Thus, the consumed power of a logic can be reduced.Type: GrantFiled: December 24, 1996Date of Patent: December 21, 1999Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Hiroyuki Morinaka, Hiroshi Makino, Kimio Ueda, Koichiro Mashiko

Patent number: 6001518Abstract: A reversible heat-sensitive recording medium has a substrate where a reversible heat-sensitive recording layer and a protective layer are successively formed on top of it. The reversible heat-sensitive recording layer is formed by a reversible heat-sensitive recording material including a leuco dye and a color developing/reducing agent. The color developing/reducing agent is a combination of two kinds of color developing/reducing agents, one with a high color developing ability and the other with high image preservation and stabilization capabilities. The two agents are combined at a ratio between 1:4 to 4:1. Thus a reversible heat-sensitive recording material with a fine color developing ability and high image preservation and stabilization capabilities can be obtained.Type: GrantFiled: April 9, 1998Date of Patent: December 14, 1999Assignee: Kyodo Printing Co., Ltd.Inventors: Haruhiko Ohsawa, Shin-ichi Koizumi, Hiroyuki Morinaka, Minoru Fujita

Patent number: 5859800Abstract: A highly reliable data holding circuit with a reduced circuit area and reduced power consumption is disclosed. Output terminals (DO, DOB) are connected to input terminals (DI, DIB) receiving signals at H and L levels (potentials VDD and GND) in mutually exclusive relation through transistors (MN2, MN1) and inverters (INV1, INV2). Input terminals of the inverters (INV1, INV2) are connected to power supplies (VDD) through transistors (MP2, MP1) having gate electrodes connected to output terminals of the inverters (INV2, INV1), respectively. The transistors (MN2, MN1) cause a voltage drop of the signals to be applied to the inverters (INV1, INV2) by the amount of a threshold voltage (Vthn). One of the transistors (MP1, MP2) which receives a signal at L level at its control terminal provides a potential (VDD) to the input terminal of one of the inverters (INV1, INV2) which is to output a signal at L level, compensating for the voltage drop by the amount of the threshold voltage (Vthn).Type: GrantFiled: October 14, 1997Date of Patent: January 12, 1999Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kimio Ueda, Hiroyuki Morinaka, Koichiro Mashiko

Patent number: 5781062Abstract: A logic circuit (L.sub.i) is connected between a virtual power supply line (VDDV) connected to an actual power supply (VDD) through a PMOS transistor (Q1) and a virtual grounding line (GNDV) connected to an actual ground (GND) through an NMOS transistor (Q2). During an active period, the transistors (Q1, Q2) are constantly conducting, and the virtual power supply line (VDDV) and virtual grounding line (GNDV) are at the power supply potential (VDD) and ground potential (GND), respectively. During a standby period, the transistors (Q1, Q2) periodically repeat conduction/non-conduction to charge and discharge the virtual power supply line (VDDV) and virtual grounding line (GNDV), suppressing power consumption while preventing loss of information held by the logic circuit (L.sub.i).Type: GrantFiled: January 3, 1996Date of Patent: July 14, 1998Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Koichiro Mashiko, Kimio Ueda, Hiroaki Suzuki, Hiroyuki Morinaka
