Title: Method for driving solid-state image pickup device
Inventor: HASEGAWA KAZUMASA
IPC: H04N5/335
Filed: 1985-09-05
Abstract: PURPOSE:To eliminate a noise due to leading or trailing of an end pulse by applying a start pulse in opposite phase to the end pulse to other solid-state image pickup element as soon as the timing of the end pulse of one solid-state image pickup element is given. CONSTITUTION:Since the end pulse output of the 1st solid-state image pickup element is inverted by an inverter 109, the phase of the end pulse 504 of the 1st solid-state image pickup element and the phase of the start pulse 505 of the 2nd solid-state image pickup element are inverted. The noise due to the trailing and leading of the end pulse of the 1st solid-state image pickup element is cancelled by the noise due to the leading and trailing of the start pulse of the 2nd solid-state image pickup element. Thus, the output signal waveform is not uniformed even during the period of t4-t6 as shown in a waveform 509 and a normal signal waveform is outputted.

Title: A/d conversion circuit
Inventor: SHIOZAKI YUKINORI
IPC: H03M1/14
Filed: 1990-07-25
Abstract: PURPOSE:To improve the resolution for A/D conversion without increasing the number of comparators by generating a step signal corresponding to a digital code and subtracting an analog signal outputted from a signal generating section from an analog signal outputted from a sample-hold(S/H) circuit section. CONSTITUTION:A counter 9 outputs a digital code. A signal generating section 4 generates a step analog signal corresponding to the digital code. The S/H section 2 holds an analog signal from a pre-stage analog circuit 1 for a prescribed period. A subtractor section 3 subtracts an analog signal from the signal generating section 4 from the output analog signal from the S/H section 2. A reference voltage generating section 5 generates a reference voltage at every resolution of A/D conversion. Thus, the resolution of A/D conversion is enhanced without increasing the number of comparators being components of the A/D converter circuit.

Filed: 1988-08-05
Abstract: PURPOSE:To obtain an economical prime mover by converting the imbalance of the position energy of a weight which is generated by utilizing a shape memory alloy to the kinetic energy and turning a rotary shaft. CONSTITUTION:As for an arm 6 made of the shape memory alloy which possesses the equal dimension and equal temperature characteristic, one edge side is fixed onto the boss 5 of a rotary shaft 4, and a weight 7 having a certain mass is fixed at the other edge side.
