IPC: H02M7/48
Filed: 1980-08-11
Abstract: PURPOSE:To facilitate the protection and cooperation of an inverter device and a load by switching the inverter from a voltage controlling loop to a current controlling loop when the output current of the inverter is limited, thereby arbitrarily selecting the current limiting value. CONSTITUTION:The first sensor 4 for detecting the output voltage of an inverter 1 and the second sensor 5 for detecting the output current of the inverter 1 are provided, and a switching circuit 10 for switching switches 10a, 10b from the first state to the second state when the output current is increased higher than the prescribed current limiting value of the output signal of the second sensor 5 is provided.  When the switches 10a, 10b are the first state (the switch 10a is closed and the  switch 10b is opened), an amplifier 11 receives the output signal of the first sensor  4, and when the switches are the second state (the switch 10a is opened, and the switch 10b is closed), it receives the output signal of the second sensor 5, thereby  amplifying the input and controlling the phase of a gate signal with the output signal of the amplifier.

Title: Method and device for inspecting appearance defect of body
Inventor: MATSUOKA KATSUTOSHI
IPC: G01N21/84
Filed: 1985-05-27
Abstract: PURPOSE:To inspect the appearance of a body speedily and inexpensively by detecting variation in the quantity of light caused by a moving object being a material body to be inspected by an optical sensor in the form of a time series of an electrical signal, and analyzing its aperiodicity. CONSTITUTION:A bearing is rotated at a constant rotating speed and irradiated with light from an optical fiber 17 from below. The irradiated light is transmitted through a holder, photodetected by optical fibers 18 and 19, and converted into an electrical signal (original signal) by a preamplifier circuit 22 or 23. The original signal is inputted to a comb-shaped notch filter to check the mean value of a signal after a signal component of frequency corresponding to a normal shape while the amplitude of the frequency component corresponding to the normal shape is evaluated without passing the signal through the comb- shaped notch filter. Then, an amplitude discriminating circuit 29 detects abnormality of claw clamping and a mean value discriminating circuit 30 detects a defect such as nonclamping. An amplitude discriminating circuit 31 detects the deformation of the holder and a mean value discriminating circuit 32 detects abnormality of the holder.

Abstract: PROBLEM TO BE SOLVED: To automatically plat characters or the like on a predetermined line on a small paper by a method wherein a pen arm shiftable to XY-directions to the surface of a paper is provided and, at the same time, a sub-scale is arranged shiftably to a X-direction or to a Y-direction. SOLUTION: When characters or the like are plotted along the line G of the small surface of a paper H, the ruled line Kj of a sub-scale 40 is brought in line with the line G of the surface of the paper H. In this case, when the ruled line Kj is inclined to the line G or the line is parallel to a X-axis, the surface of the paper H is slipped to a main body 11 so as to bring the line G in line with the ruled line Ka.

Abstract: PURPOSE:To obtain an arithmetic unit which effectively uses registers, by exchanging high-order digits and low-order digits of input data by a selector circuit in case of the operation between contents of the high-order digit side and the low-order digit side of registers. CONSTITUTION:In case of the operation between the high-order digit side of an item to be operated and the low-order digit side of an arithmetic item, a selector circuit 31 selects the high-order digit side of the output signal of a selector 20 and supplies it as the arithmetic item of an ALU 41 of the low-order digit side. Since the input of the item to be calculated of the ALU 41 of the low-order digit side is fixed to the low-order digit side of the register output which is the item to be calculated, the result from the arithmetic operation between the low-order digit side of the item to be calculated and the low-order digit side of the arithmetic operation item appears in the output of the ALU 41. In case of the arithmetic operation between the upper digit side of the item to be calculated and the low-order digit side of the operation item, a selector circuit 30 selects the low-order digit side of the output signal of the selector 20. This output and the high-order digit side of the output of a selector 21 are supplied to an ALU 40, and the arithmetic operation result appears in the output of the ALU 40.

Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a low pressure mercury vapor discharge lamp which is capable of preventing deterioration of efficiency in a low power region and in a low temperature environment and saturation of an optical output in a high power region. SOLUTION: A low pressure mercury vapor discharge lamp 1 is provided on the inner face side of a light emitting tube 2, with a phosphor layer 3 of a three-wavelength type and an outer tube 4 in a coaxial manner. There is provided a gap 6 having mercury enclosed between the light emitting tube 2 and the outer tube 4.

Abstract: PROBLEM TO BE SOLVED: To provide a printing control apparatus capable of housing many pages by an accumulation memory within the range capable of corresponding to the printing speed of a connected printer. SOLUTION: When all of the data stored in a work memory 26 are compressed, they are expanded to be successively sent to a printing part 13 and, when all of the data are not compressed, they are sent to the printing part 13 as they are.
