Title: Uninterruptive switching controller in generator of ship
Inventor: OGINO HIROYUKI
IPC: H02J9/08
Filed: 1993-10-07
Abstract: PURPOSE:To simplify the control system by canceling a holding command for the number of rotation of a main engine, when load transfer to a preparatory generator is completed. CONSTITUTION:When a speed reducing command signal for a main engine is detected by a speed reducing command detector 1, a preparatory generator is started, and a holding command for maintaining the number of rotations of the main engine is outputted from a number-of-rotations maintaining command issuing apparatus 7. And when the completion of load transfer to the preparatory generator is detected by a load transfer completion detector 9, a signal is outputted to a number-of-rotation maintenance canceling apparatus 11 and holding command is canceled, on the basis of a signal from the load transfer completion detector 9 or a timer 6, and the speed of the main engine is reduced. And even when the load transfer to the preparatory generator has not been completed, a signal is outputted to the number-of-rotation maintenance canceling apparatus 11, and the speed of the main engine is reduced when time set by the timer 6 has passed. Consequently, it becomes possible to simplify the control system.

Title: Etching method utilizing ion beam
Inventor: YAMAGUCHI ATSUMI
IPC: H01L21/3065
Filed: 1988-10-04
Abstract: PURPOSE:To improve symmetric property of etching by generating a set of at least two ion beams and simultaneously scanning in such a manner that they have opposite moving directions on the scanning surface to eliminate redeposition. CONSTITUTION:A region 1 to be subjected to an etching process is scanned by two ion beams 2. First, the ion beams 2 focused to have about 1mum diameter are scanned in the scanning direction 3 from the center of the region 1. In both outside regions of the first scanned part 4, the scanning is carried out subsequently and this scanning sequence is then repeated successively. In this way, a region 4 to be etched is wholly etched. In this case, if the two ion beams 2 are successively scanned in the opposite directions, the material scattered by the ion beams is scarcely redeposited. Further, grooves are formed in a symmetrical shape so that the symmetrical property of the etching can be improved.

Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To prevent a metastable state of a semiconductor integrated device which has a holding function. SOLUTION: The elements (6) to (8) detect the changes of data signals received from an input (A). An element (11) decides to or not to show the above changes of the data signals to the elements (12) and (13) based on the state of a transmission gate element (1). The elements (12) to (15) control the clock signals which are received from an input (B). The delay in the buffer of an element (9) is controlled to make the changes of the data signals pass through the element (1) while an element (13) is closed. Then the buffer of the element (7) decides a time when the element (13) is kept closed. In such an operation of a circuit that is shown in a diagram, the signals received from both inputs (A) and (B) never simultaneously change at the element (1). Thus, a metastable state of a semiconductor integrated device can be prevented.

Title: Production of optically active 1-@(3754/24)1-naphthyl)ethylamine
Inventor: NAKAI SAKIE
IPC: C07C209/88
Filed: 1992-09-21
Abstract: PURPOSE:To resolve (RS)-1-(1-naphthyl)ethylamine in excellent yield and optical purity by using a specific optically active tartaric acid anilide obtained from inexpensive raw material in high yield and capable of industrially feeding as a resolving agent. CONSTITUTION:An optically active tartaric acid anilide derivative (e.g. o-nitro- tartaric acid anilide or p-methoxy-tartaric acid anilide) of the formula (R is methoxy or nitro) as a resolving agent is brought into contact with (RS)-1-(1- naphthyl)ethylamine in a solvent to prepare a sparingly soluble diastereomer salt. Then, a solution of the salt is cooled and/or concentrated to crystallize and separate the sparingly soluble diastereomer salt from the solution. On the one hand, residual mother liquor is cooled and/or concentrated to deposit and separate a readily soluble diastereomer salt from the liquor. Since the optically active tartaric acid anilide derivative of the formula used as the resolving agent is sparingly soluble in water, it can be recovered in high yield from the diastereomer salt solution, and is hardly decomposed or racemized in a recovery process.
