Title: Gaussian lens
Inventor: YAMAZAKI SHOICHI
IPC: G02B9/42
Filed: 1990-10-29
Abstract: PURPOSE:To enable a Gaussian lens wherein optical performance, especially axial chromatic aberration and petzval's sum are excellently corrected for by specifying a third Abbe's number for a Gaussian lens. CONSTITUTION:When Abbe's number for a third lens of meniscus form, having a negative refraction power, whose convex face is directed to an object is represented by formula I, the conditions of formulae II and III are satisfied. In the formula I, Ng is an index of refraction for the g ray, Nd is an index of refraction for the d ray, NF is an index of refraction for the F ray and Nc is an index of refraction for the C ray. Further, the formulae II and III are conditional formulae when glass with high anomalous dispersion is used for the third lens. By using glass satisfying the conditional formulae, the axial chromatic aberration can be extremely reduced and high resolving power can be obtained at the respective wavelengths of red, blue and green. Accordingly, the axial chromatic aberration becomes small and the lens becomes light. By balancing the various aberrations, high resolution is attained at the respective wavelengths of red, blue and green.

Title: Dc-dc converter for thin film transistor liquid crystal display
Inventor: BUN SHIYOUKAN
IPC: G09G3/36
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To improve power conversion efficiency by introducing a polarity signal and an inverted polarity signal which have mutually opposite phases, and constituting a circuit by using PMOS transistors and NMOS transistors which are low power elements, diodes, and capacitors. SOLUTION: A polarity signal POL is introduced. By its pulse waveform, a DC power supply VDD forms a pulse waveform at a node N1, via a PMOS transistor M61 and an NMOS transistor M62. By a capacitor C61 and diodes D61, D62, a pulse waveform whose voltage is about twice the DC power supply VDD is formed. On the other hand, an inverted polarity signal POLB is introduced, and a pulse waveform of opposite phase is formed by a similar circuit constitution. Both of the pulse waveforms are synthesized at a node 5 and charge a capacitor C63. The charged voltage is outputted as a smoothed DC voltage VCC, which is about twice the DC voltage VDD. Thereby the power consumption of a DC-DC converter for a thin-film transistor liquid crystal display is reduced, and the power conversion efficiency can be improved.

Title: Gain variable amplifier
Inventor: HARASAWA KATSUYOSHI
IPC: H03G3/10
Filed: 1988-11-24
Abstract: PURPOSE:To eliminate the fluctuation of a direct current level in an output signal when a gain is variable by shunting a current into a first differential pair output signal current and a load resistor side by a differential pair, which controls an output signal current, detecting the fluctuation of the direct current to be obtained from the load resistor side and adding the direct current, which corresponds to fluctuation quantity, to the output signal current. CONSTITUTION:The common emitter part of the first differential pair of transistors 1 and 2, which have an input signal terminal as a base, and a load resistor R1 are connected to the respective collector parts of the second differential pair of transistors 3 and 4 to control the gain. Then, the division rate of the current, which flows to the first differential pair and the resistor R1, is determined. A voltage V1 to be obtained from this load resistor R1 is compared with a reference voltage Vref by the third differential pair. The respective collectors of two transistors 5 and 5, which have a same phase, in this third differential pair are respectively connected to the collector parts of the respective transistors 1 and 2 in the first differential pair. Then, the direct current level fluctuation of a signal to be outputted by a current I3, which is generated by this third differential pair, is compensated. Thus, the output direct current level of a variable amplifier is not fluctuated at all even when the gain is variable.

IPC: H02P8/32
Filed: 1986-12-12
Abstract: PURPOSE:To reduce vibration of a stepping motor after stopping by setting an excited state just before stopping to single-phase excitation. CONSTITUTION:ROM2 generates a driving pulse pattern for a step ping motor 4 according to an address assignment of a motor drive and control circuit 1. A motor driving circuit 3 drives the stepping motor 4 by single-phase or two-phase excitation according to said driving pulse pattern generated from the ROM2. In this case, if the stepping motor 4 is driven by repetition of two- phase or single-phase excitation and two-phase excitation, the stepping motor 4 is caused to stop in a single-phase excited state without fail. As a result, vibration is decreased as compared with stopping after two-phase excitation drive and a noise of apparatus is reduced therethrough.
