Title: Inverter control circuit
Inventor: KATSUTO MASAYUKI
IPC: H02P25/04
Filed: 1984-10-17
Abstract: PURPOSE:To stably operate an inverter without stalling a motor by reducing the frequency of the inverter in the prescribed frequency when the current of the motor increases and becomes the state exceeding a stalling preventing level. CONSTITUTION:Since the current I0 of a motor 4 for detecting through a current detector 7 and a current transformer 6 is lower than a stalling preventing level at normal time, a level discriminator 8 does not energize a signal 8a. Thus, an inverter controller 9 inputs a control signal 9a to an inverter 3. Here, when the slip frequency fs of the motor 4 increases due to certain cause and the current I0 exceeds the stalling preventing level, the discriminator 8 energizes the signal 8a. Accordingly, the value of the output frequency command is abruptly reduced in response to the signal 9a of the controller 9. Thus, the slip of the motor 4 increases to prevent the motor from stalling.

Title: Dry etching method
Inventor: HANADA KAORU
IPC: C23F4/00
Filed: 1993-08-31
Abstract: PURPOSE:To perform highly reliable etching of a silicon material layer while utilizing a sidewall protection effect of deposited substances using an etching apparatus for single wafer processing. CONSTITUTION:When etching a first gate electrode G1 connected directly to an embedded contact 11 of an Si substrate 1 of SRAM, an RF bias, 2MHz in frequency and 5 to 10W in power is applied to a substrate at the time of over etching, utilizing a microwave plasma etching apparatus with magnetic field and Cl3/CH2F2/SF6 mixed gas. Therefore, generation of notch on the surface of edge 10 of the first gate electrode G1 can be prevented with the sidewall protection effect of the carbonic polymer derived from CH2F2. Since an ion incident energy is optimized and excessive deposition of carbonic polymer is controlled depending on the bias application condition, deterioration in etching rate and uniformity can be prevented even in the latter half of the lot in the single wafer processing.

Filed: 1997-08-12
Abstract: PROBLEM TO BE SOLVED: To improve water permeability just after construction and reduce the lowering of water permeability attendant on use by using aggregate having specific values for the minimum aggregate size, the maximum aggregate size and a uniformity coefficient, as aggregate at least for a surface layer portion. SOLUTION: Aggregate whose minimum aggregate size is 4 to 2 mm, maximum aggregate size is 20 mm or less, and uniformity coefficient is 1 to 5 is used at least as aggregate for a surface layer portion and the void fraction of the part where aggregate is used, is 20% or higher. And then if aggregate whose minimum size is less than 2 mm is used, the initial water permeability is low and a decrease in the water permeability attendant on use is large. If its minimum size is over 4 mm, though a decline in water permeability is low, initial water permeability is low. If the uniformity coefficient is less than 1, the initial water permeability is low, and a lowering of water permeability is large. On the contrary, if the uniformity coefficient is higher than 5, the initial water permeability is low.

Inventor: RAINERU GEERUMAN
IPC: H04N9/75
Filed: 1993-09-01
Abstract: PURPOSE: To provide a chromakey which satisfactorily adjusts data of a picture locally with respect to time. CONSTITUTION: When a background picture signal will be inserted to a key color-characterized key color area of a foreground picture signal, fading operation is performed between picture signals in a proportional area depending upon a control signal, and an intermediate color occurring in a proportional section of the foreground area is converted to a new intermediate color, and this new intermediate color constitutes conversion from the color of the foreground picture signal to the color of the background signal.  For the purpose of most suitably adapting in this chromaky method, individual proportional sections for areas of various color positions of a foreground picture signal L(t) are properly fixed, and a distance Lx between the color position of each area and that of the key color is individually determined by using base parts and top parts of their edge parts, and a control signal K is generated for each area dependently upon the distance of the color position determined for each area.
