Title: Control circuit having integrated circuit with delay of predetermination start for mos power transistor
Inventor: ARUBERUTO GOORA
IPC: G11B19/00
Filed: 1988-12-21
Abstract: PURPOSE: To make a preliminary setting accurate for the starting delay by providing an SCR circuit parallelly to a related threshold circuit corresponding to a charging voltage, with a method allowing the start when the charging voltage of a R-C electrical network reaches a prescribed threshold value. CONSTITUTION: A voltage Vr in operation charges a capacitor Cb at a voltage Vb while a capacitor Cx begins charging through a resistor Rx. With the charging current of the capacitor Cx reaching a voltage that conducts the NPN transistor Q3 of an SCR circuit, the terminal voltage of a resistor R2 in the related threshold circuit so rises as to conduct the PNP transistor Q2, Q1 of the SCR circuit as well, so that the capacitor Cx causes a sharp rise of voltage in the gate of a MOS transistor M to start conduction. The movement of the voltage Vx incident to the charging time is such that, following an initial slow rise, the voltage momentarily rises rapidly, starting the MOS transistor M and that, with a slow fall continuing subsequently, a starting delay capable of accurate preliminary setting is realized, as is the clear conduction of the MOS transistor M.

Title: Optical waveform measuring instrument by light sample
Inventor: TAKARA HIDEHIKO
IPC: G01J11/00
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To make the eye pattern measurement with high time resolution possible by generating a specific sampling light pulse train of an ultra-short pulse width and low jitter by repetition of low pulses. SOLUTION: The output of a pulse light source 13 is amplified by a first optical amplifier 14-1 and is made incident on an optical gate switch 23. On the other hand, the other of the branched outputs of an oscillator 11 is divided down in frequency to 1/M.N by a frequency dividing circuit 12. An electric pulse generator 22 is driven by the electric signal of the divided down lowfrequency f0 -NΔf, by which the electric pulse trains of the repetitive frequency f0 -NΔf and pulse width 100ps to 1ns are generated. The optical gate switch 23 is driven by matching the timing with the light pulse trains by such electric pulse signals, by which the light pulse train of the repetitive frequency M(f0 --NΔf) is divided down to the light pulse train of the low-repetitive frequency f0 -NΔf.  At this time, the electric pulse signals include the jitter, but the frequency dividing is executed without receiving the influence of the jitter by gating the light pulses near the center of the electric pulses.

Title: Load abnormality detecting circuit
Inventor: SHIO TAKEHISA
IPC: G01R31/02
Filed: 1990-11-26
Abstract: PURPOSE:To detect the load abnormality of a body earth type load circuit having no return wire by providing a transistor performing switching operation by the voltage drop generated across both terminals of the current detection resistor provided in series on the side of the output line of the load circuit when a load current flows. CONSTITUTION:When voltage drop is generated in a current detection resistor R2, a transistor Q3 is turned ON. When the potential of an output wire 2 is zero at this time, a load short-circuit is generated. This state where the transistor Q3 is turned ON and the potential of the output line 2 is zero is detected by an NOT element U3 and an AND element U5. In such a case that no voltage drop is generated in the current detection resistor R2 and the transistor Q3 is turned OFF and the potential of the output wire 2 is high, load disconnection is generated. This state where the transistor Q3 is turned OFF and the potential of the output wire 2 is high is detected by an NOT element U2 and an AND element U4.
Patent JP-H02169272-A (JP)
Title: Color converter
Inventor: MOROO JUN
IPC: H04N1/46
Filed: 1988-12-22
Abstract: PURPOSE:To contrive higher color reproduction properties at the time of changeover of a paper, an ink or the like by printing a color calibration color scale on a predetermined part of a paper simultaneously with printing on the paper, and correcting the next color printing so as to obtain a density coefficient equivalent to the color scale. CONSTITUTION:At the time of the n-th run of printing, a color scale printed in the (n-1)th run is read by a CCD sensor 16, and the read value is inputted to a color calibrating part 15. The part 15 receives outputs from the sensor 16 and a YMC color scale generating part 17, determines coefficients in a masking equation, and writes the coefficients into a non-volatile memory 14. By such a process, it is possible to determine the coefficients to be used in the next run of printing. Since both an actually outputted signal and a read color signal are clear, the color calibrating part 15 can comform printing to the color scale at the time of determination of the coefficients for color conversion. Thus, the coefficients determined at the n-th run of printing are used at the time of the (n+1)th run of printing. By these operations, high-quality printing can be performed even upon changeover of a paper.

IPC: G21B1/00
Filed: 1989-12-12
Abstract: PURPOSE:To enable increase of rigidity without enlarging the section of a conductor, by providing an inside coil and an outside coil which are disposed in proximity to each other in the radial direction. CONSTITUTION:When electricity is made to flow through a feeding part 7A and a discharging part 7B of a poloidal field coil 1, the outer peripheral side of an inside coil 1A turns to be of high temperature and the inner peripheral side thereof to be of low temperature by a cooling operation of a cooling duct 4A provided on the outer peripheral side thereof, while the inner peripheral side of an outside coil 1B turns to be of high temperature and the outer peripheral side thereof to be of low temperature by the cooling operation of a cooling duct 4B provided on the outer peripheral side thereof. As the result, a difference in thermal elongation in the circumferential and radial directions occurs in the coils 1A and 1B. Even when the coils 1A and 1B expand by heat, the outer periphery of the coil 1A and the inner periphery of the coil 1B are not separated from each other. At the same time, a tensile force is given to a bind wire 5 by the thermal elongation in the radial direction of each coil, the two coils are made to approach each other as a counterforce thereof, a compressive force is applied to a packing 2 and thus strong integration is attained. In this case, the rigidity is larger than that in the case when the coils 1A and 1B are disposed separately.
