Title: Synchronization clock generator
Inventor: SUKOTSUTO MAAKINSON
IPC: H03L7/08
Filed: 1989-10-27
Abstract: PURPOSE: To prevent the accumulation of clock skew errors by compensating timing skew so as to make cycles symmetrical (equal interval) with each other. CONSTITUTION: Clock distribution on respective boards (circuit boards) 52, 70A and 70B is performed by a phase locked loop(PLL) circuit 72 and a gate array (SCR) tar distribution 74 and the PLL circuit 72 is laid out uniformly on all the boards of a system. The PLL moves and controls the transition point of clock signals inputted to the gate array so as to be matched with reference clock signals, matches gate array output with the reference and obtains frequency multiple clock signals for which the skew errors are small and symmetry between the cycles is improved. Thus, the storage of the clock skew errors is prevented.

Abstract: PROBLEM TO BE SOLVED: To make an energy cost extremely low by connecting a gas turbine to a generator, and using the gas turbine waste gas for a pre-heating of combustion air by passing the gas turbine waste gas through a pre-heater. SOLUTION: Air Al is jetted into a compressor 11 which is driven by a gas turbine 13 and is compressed, and in a combustor 12, a gas G is charged to the compressed air and burned. By introducing the gas G to the gas turbine 13, a generation is performed by a generator 14, and at the same time, the waste gas of the gas turbine 13 is passed through a pre-heater 3 for combustion air A, and the combustion air A is pre-heated. In this case, a denitration is performed when the waste gas which has passed the pre-heater 3 is discharged to the atmosphere, and for this denitration, demineralized water is fed to the combustor 12.  Then, when the waste gas, which has passed through a waste gas treating equipment 15 such as a wet scrubber from a waste heat boiler 5, is discharged to the atmosphere from a chimney 16, the waste gas at approx. 200 deg.C, which has passed the pre-heater 3, is injected for the prevention of a white fume.

IPC: G06F12/00
Filed: 1989-10-30
Abstract: PURPOSE:To eliminate the useless storage areas by storing the data base record as the history record for each record prior to the update of the data base record. CONSTITUTION:An integrated control part 11 informs a data base control part 14 of a request for update of a data base. The part 14 extracts the correspond ing data base record out of a data base file store part 15 and copies the record to a data base history file store part 16 to update the data main body part of the record. Thus, each data base record is updated and a new data base history record is produced in a data base history file for each update of the data base record. As a result, the data base records are updated for each record and at the same time these records are stored for each record prior to the update of the data base record. Thus, the increase of a data base storage area can be avoided.

Title: Protection film for thin film solid-state element
Inventor: UMEZAKI HIROSHI
IPC: G11C11/14
Filed: 1987-11-11
Abstract: PURPOSE:To obtain a protection film with low stress and high reliability by driving an ion by using high molecular resin and also in the neighborhood of its surface. CONSTITUTION:As the protection film, the high molecular resin, for example, polyimide resin 6 is used. In the high molecular resin 6 in which the ion is driven, weak connection in a molecular is broken, which forms graphite structure where the coupling of carbon is formed in net shape. Therefore, mechanical strength can be intensified remarkably more than an ordinary high molecule, and also, penetrability for a water content can be decreased. Meanwhile, the stress in an area other than the area on which the ion is driven is small because the property of the high molecular resin can be shown as it is. In such a way, it is possible to obtain the protection film with the low stress and the high reliability.
