Title: Photoelectric transfer device
Inventor: SHINOHARA MASATO
IPC: H04N5/369
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To reduce the current consumption when incident light is stronger than required by controlling an overcharge leakage means based on a quantify of signals output from a photoelectric transfer element to set a limited value for the optical signal current. SOLUTION: The potential of a terminal 6 is so determined that a limiting value for the emitter current of a photo transistor may be equal to the drain current of a MOS transistor 5 in a saturated region. The potential at the drain of the MOS transistor 5 is low, so the potential applied to the gate of a transistor 7 is low and the drain current is sufficiently smaller than the optical signal current. When the emitter current reaches the limiting value, however, the MOS transistor 6 comes to a saturated region and therefore the gate potential of the transistor 7 sharply rises and the photoelectric current generated in a photo transistor 1 is caused to flow as the drain current of the transistor 7 and the emitter current is not caused to flow beyond the limited value.  Even if optical signal charges are generated beyond the limiting value, the consumed power of a photoelectric transfer device can be kept within a certain level.

IPC: F27D9/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a mechanical analyzer to be used for either a dynamomechanical analyzer or a thermo-mechanical analyzer. SOLUTION: A dynamo- and a thermo-mechanical analyzer has a slide 8 which has a large displacement space, a low friction, and a small mass and is to be driven vertically in an air bearing guiding apparatus. The position of the slide 8 is measured by converting two output signals in phases at right angles and emitted by an optical encoder, which has high partial resolution function and a long path, into digital signals and interpolating the signals. In this case, force is applied to the slide 8 by a linear permanent magnet motor 11 having high power, high linearity of the power, and low sensitivity to temperature change. The position signals produced from output signals in phases at right angles converted into digital signals and interpolated are analyzed as a function of the applied force and the viscoelastic properties of a sample of a material are computed.
