Title: Boosting chopper device, power supply device, discharge lamp lighting device, and lighting device
Inventor: SHIRATA NOBUYA
IPC: H02M3/155
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To improve output voltage leading characteristics and to reduce power loss due to a starting means. SOLUTION: A boosting chopper device has a main circuit 3 that includes a boosting inductor and a switching means in series and a smoothing means 4 that is connected between both terminals of a switching means 3b, and switches the switching means 3b by a control means 5. In this case, a starting means 6 is used to activate forcibly, power is supplied from a feedback power supply 7 that is electromagnetically coupled to a boosting reactor 30 to a control power supply after starting, and at the same time the starting means 6 is stopped by an operation stopping means.

Inventor: ITO MASAHISA
IPC: G01T1/17
Filed: 1990-05-28
Abstract: PURPOSE:To make it possible to adjust dead time of an X-ray detector system only by one variable resistor and to know the dead time simply as the length of a TTL digital pulse by an oscilloscope or the like, by changing continuously the width of an output pulse waveform outputted from a pulse-height discriminator of the X-ray detector system. CONSTITUTION:Receiving a signal from a preamplifier, a linear amplifier (AMP) shapes its waveform to be of a Gaussian type by a differentiating circuit and an integrating circuit incorporated therein. In a pulse-height discriminator (SCA), a signal of the AMP in the front stage is subjected to pulse-height discrimination by LLD (Lower Level Discriminator) and outputted as a rectangular digital pulse. By using a variable resistor in place of a fixed resistor determining a time constant (which is determined by a resistance and the capacity of a capacitor and takes a fixed value generally) of output-stage IC which determines an output pulse width of a TTL level, in the pulse-height discriminator of an X-ray counter, the output pulse width is changed continuously.

Title: Photoelectric conversion device
Inventor: KATSUUMI KAZUNARI
IPC: H01L27/146
Filed: 1986-06-13
Abstract: PURPOSE:To reduce costs without adding processes by forming feedback resistors of a signal amplifier, a dummy signal amplifier and a differential amplifier on an insulating substrate in a same layer with sensor lower electrodes and gate electrodes. CONSTITUTION:Feedback resistors of a signal amplifier 27, a dummy signal amplifier 28 and a differential amplifier 29 are formed by thin film technology as patterned resistors simultaneously by forming them on an insulating substrate in a same layer with sensor lower electrodes 13 and 14 and gate electrodes 33. As these feedback resistors must have high resistance values and it is necessary to form narrow patterns to obtain the high resistance values, the defective resistors may be caused by defective patterns. However, if there is a defect, a resistor chip is bonded to bonding pads 41 and 42 exposed on both sides of the feedback resistor to operate the device normally.

Title: Variable impedance circuit
Inventor: KATAKURA MASAYUKI
IPC: H03G3/10
Filed: 1978-11-09
Abstract: PURPOSE:To realize a floating type variable impedance circuit which can easily be integrated, by using a couple of differential transistors. CONSTITUTION:Current sources 12 and 22 are those whose output currents are controlled by control voltages VC1 and VC2 applied to control terminals 3a and 3b respectively and current sources 11 and 21 supply currents a half as much as those of current sources 12 and 22. In variable resistance elements R1 and R2, collectors of a couple of transistors Q12 and Q21 are connected to their bases and Q11 and Q22 are not connected together. Viewing R1 and R2 from terminal 1, R1 is high in impedance because of a reverse PN junction and R2 has impedance (r2). Further, R2 is high in impedance and R1 has a value of (r1) being viewed from terminal 2. Circuit R can therefore be considered a reverseparallel-connection circuit of R1 and R2 with a connected voltage follower and a ratio of (r1) to (r2) becomes equal to that of IC1 to IC2.
