Title: Drive circuit for stepping motor
Inventor: MIYAGAWA YOICHI
IPC: H02P8/00
Filed: 1986-11-12
Abstract: PURPOSE:To detect the lifetime of a battery easily only by observing one terminal by simultaneously changing over two output signals from a stepping-pulse generating circuit for driving a stepping motor to reverse polarity. CONSTITUTION:When the lifetime of a battery is detected, i.e., when an output signal from a battery-lifetime detector 15 is at an 'H' level, both output pulses of a stepping motor terminal 9 and a stepping motor terminal 10 are at 'L'. When the output signal from the battery-lifetime detector 15 is at an 'L' level, inversely, a changeover circuit 6 is changed over, and both output pulses of the stepping motor terminal 9 and the stepping motor terminal 10 are at the 'H' level. Potential difference between the stepping motor terminal 9 and the stepping motor terminal 10 as driving sources for a stepping motor 16 does not fluctuate even when the output signal from the battery-lifetime detector 15 changes. Accordingly, the stepping motor 16 is driven normally.

Title: Feature detection method and system for article
Inventor: GOLD DAVID G
IPC: G06K7/10
Filed: 1986-11-14
Abstract: A method and system for sensing a characteristic (e.g. translucency) of a document (10) utilises radiation (17) from a specific window area (16) of the document (10). The radiation (17) is sensed by a sensor (18) with pixel dissection (P1 - P3), that affords pixels (P2) of a central location of the window area (16), a greater (x2) weighting so as to attribute enhanced significance to the central portion of the window area (16), whereby tolerance to misalignment with respect to the window area (16) is increased. Data signals in accordance with the weighted pixel signals are compared (62 Fig 3; 120 Fig 6) with stored values (64 Fig 3; 122 Fig 6) for the purpose of document authentication (66 Fig 3; 124 Fig 6). Pixel-weighting techniques used include filtering incident and transmitted light (46, 54 Fig 3, Fig 4), algebraically weighting derived signals (Figs 5, 6), and overlapping the sensed pixels (Fig 7).

Filed: 1989-10-19
Abstract: PURPOSE:To execute the operation of track servo even for the optical recording medium of a continuous servo system, and to obtain a small-sized and simple device by providing a means to detect independently the light outputs of three semiconductor lasers. CONSTITUTION:When a first light spot 11 advances on a track in the direction of an arrow mark in a figure, difference between quantity of light of reflected light in a second light spot 12 and the quantity of light of the reflected light in a third light spot 13 is caused accordingly to a deviation from the center of the track. Each reflected light is fed back to a second and a third semiconductor lasers, and the change of the quantity of light of the reflected light is detected as the change of the light output of the semiconductor laser. Accordingly, a track error signal can be obtained from the difference between the light output of the second semiconductor laser and the light output of the third semiconductor laser. Thus, the operation of track servo can be executed not only for the optical recording medium of a sample servo system but also for the optical recording medium of the continuous servo system, and the small-sized and simple device can be obtained.

Title: Driving method for liquid crystal display device and liquid crystal display device using the same
Inventor: OSHIRO MIKIO
IPC: G09G3/36
Filed: 1999-09-24
Abstract: PROBLEM TO BE SOLVED: To provide the driving method for a liquid crystal display device capable of writing a multilevel signal on a display electrode sufficiently even when bluntness is generated in a gate signal and to provide a liquid crystal display device using the same method. SOLUTION: In the state shown in the figure 1 (a), a gate delay is not generated in a gate signal Gn and the gate signal Gn has a pure rectangle shape. In the state shown in the 1 (b), the gate delay is generated in the signal and a gate signal Bf on a gate bus line 2 is blunted. However, a data signal Df is not outputted at the same timing as that of a data signal Dn and the changeover timing of the data signal Df is delayed by Δt than that of the data signal Dn. As a result, even though a gate-off time is delayed by an amount equivalent to the bluntness of the gate signal Gf, since the changeover time of the data signal of the data signal Df is also delayed by Δt, the original level of the data signal Df can be correctly written on a pixel electrode 8.
