Title: Charge pump voltage converter
Inventor: SHIMODA SADAYUKI
IPC: H02M3/07
Filed: 1990-09-06
Abstract: PURPOSE:To implement two types of charge pump voltage converters in the form of a monolithic IC without increasing the chip area by sharing a part of switching transistors being employed in the two types of charge pump voltage converters. CONSTITUTION:Elements for generating a one time voltage having reverse polarity are transistors 2-5 and capacitors 6-7. A voltage -V1 having reverse polarity appears at an output terminal 8. Elements for generating a doubled voltage having same polarity are switching transistors 2, 3, 9, 10 and capacitors 13, 14. A voltage 2V1 having same polarity appears at an output terminal 15. When the two switching transistors 2, 3 are shared by charge pump converters having same polarity and reverse polarity, chip area can be reduced as compared with a case where they are implemented in the form of individual monolithic ICs resulting in an inexpensive IC.

Title: Data retriever
Inventor: HAYASHIBARA IZUMI
IPC: G11C7/00
Filed: 1994-10-03
Abstract: PURPOSE: To shorten overhead time of a CPU required for interrupt processing by providing a memory section to store retrieving data and a data to be re trieved separately to enable batch retrieval. CONSTITUTION: When a retrieving key data is inputted through a data selector 12, the data is compared with storage data stored in an FIFO memory 18 with a retrieving section 16 and with the coincidence thereof, the retrieving section 16 outputs a retrieving signal indicating the presence of the retrieving key data in the memory 8 to a CPU 20. The sequential data via the data selector 12 is stored into a FIFO memory 14 different from the memory 8. This allows a batch processing of retrieving information to increase the frequency of interruption with respect to the CPU 20 and enables the shortening of overhead time of the CPU 20 thereby achieving a higher processing speed of the CPU 20 in substance.

IPC: F24C15/16
Filed: 1987-09-24
Abstract: PURPOSE:To prevent flowing of hot water over a pan when the pan is pulled out, by a method wherein, in a gas kitchen range with a grill for domestic use, a stepped part is formed in front of a grill pan, and a wave dissipating plate is situated to the front part of a broiling net placed on the stepping part. CONSTITUTION:With a handle 1 pulled out, a glass 2 integrally situated to a glass frame by means of a screw 7, a glass frame 3, and a pan 4 are simultaneously pulled out. During grill cooking, water is placed in the pan 4. When, in the middle of cooking or on completion of cooking, the pan 4 is pulled out, and water producing hot water flows to the front of the pan 4 but is collided with a wave dissipating plate 6 having a size A longer than that of the step, formed at the front part of a broiling net 5, of the pan. A part of the hot water is splashed back to the bottom part of the pan 4, the velocity of flow of the rest is reduced by means of a gap between the wave dissipating plate 6 and the pan 4 to return the rest to the bottom of the pan 4, and is prevented from flowing over the pan 4. Also when the upside of the broiling net 5 is down for the use, no gap between the wave dissipating plate 6 and the step part of the pan 4 is formed. But, since the wave dissipating plate 6 is a size A longer than the step of the pan 4, water is prevented from flowing over the pan 4.
