摘要： A varistor having a non-linear coefficient of at least 40 and improved stability for DC stress is produced by a method including a step of mixing ZnO powder with a solvent solution of Mn and Pb compounds, a step of calcining the resultig mixture, and a step of pulverizing the calcined product to obtain a pulverized product. These steps are performed while preventing the contamination with a Group IIIb or Ia element, so that the pulverized product has MnO and PbO contents of 3-7 mole % and 0.003-0.01 mole %, respectively, and a content of impurity compounds of a IIIb or Ia element of not greater than 20 ppm by weight. The pulverized product is molded and sintered to obtain the varistor.

摘要： A drive device for a light-emitting element that improves accuracy while driving the light-emitting element at small currents for which a comparatively simple configuration is provided. The drive device includes detecting means, comparing means, a driving voltage source, and offset means. The detecting means detects a voltage corresponding to a current flowing through a first resistor for current detection. The first resistor is coupled to a light-emitting element in series. The comparing means compares a magnitude of the detection voltage of the detecting unit with a comparison voltage. The driving voltage source applies a voltage corresponding to a comparison result by the comparing means to a series circuit of the light-emitting element and the first resistor. The offset means corrects the voltage corresponding to a current flowing through the first resistor by a correction voltage.

摘要： Upon displaying a targeted stereoscopic image formed by a background image planar component and a spring-out image stereoscopic component, a stereoscopic display device controls and stereoscopically displays the spring-out image having a large parallax so that the amount of transmitted light of a light transmitting portion of a light control panel is T1. Thereafter, the amount of transmitted light of the light transmitting portion of the light control panel is switched from T1 to T2, where T2 is larger than T1. The background image having a small parallax is displayed.
