Title: Photoelectric converter
Inventor: AKAMATSU NORIHIKO
IPC: G03B13/36
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To appropriately amplify contrast components without re-integrating by a method wherein a second output is detected prior to reading out an accumulated electric charges as a first output, and a processing method of the first output is switched in response to the second output. SOLUTION: An automatic gain control output signal AGCOS from a monitoring photodiode MPD is imparted to an integration time control part. The integration time control part decides whether or not an electric charge carrying amount of each line sensor reaches an appropriate value. This decision result is sent to a CCD control part, and a BG signal, a STICG signal and the like are imparted to each line sensor based on a signal from the integration time control part and a sensor control part to control operations. A CCD clock generation part transmits a common transfer clock to a shift register SR of the line sensor, and also a SH signal is imparted to the line sensors, respectively, to control a shift gate SH. The integration time control part calculates a contrast of electric charges based on a monitor signal, to decide an amplification mode and an amplification factor.

Title: Structure of rubber crawler
Inventor: KUMANO YOICHI
IPC: B62D55/253
Filed: 1995-07-05
Abstract: PROBLEM TO BE SOLVED: To provide an increased life for a rubber crawler by a method wherein the center of the bottom of a recessed part between protrusions for preventing dislocation of a wheel adjoining each other on the longitudinal direction of a rubber crawler is offset from the center of an overlapping part. SOLUTION: Protrusions 5 for preventing dislocation of a wheel are formed in such a state to protrude from the blade part 6 of a core 1 in a zigzagging manner toward the longitudinal direction of a rubber resilient body 2. A rubber resilient body 2 between the protrusions 5 and 5 of the adjoining cores 1 and 1 are previously removed to form a recessed part 7. When a roller or an idler is rolled over the protrusions 5 and 5, an inner frame is lodged between a pair of the projections 5 and 5 to prevent dislocation of a wheel. Further, expansion parts 8 and 9 are respectively formed right below the protrusions 5 and 5. Interference of the cores 1 and 1 with each other due to horizontal displacement of the cores 1 and 1 is prevented from occurring.  The lengths of the expansion parts 8 and 9 are different from each other and the center of an overlapping part 10 between the expansion parts 8 and 9 is displaced by an offset amount C from the center of the bottom part 70 of the recessed part 7. This constitution disperses distortion and prevents the occurrence of the crank of the bottom 70 .

Title: Solid-state image pickup element
Inventor: KURIHARA HAJIME
IPC: H04N1/028
Filed: 1984-09-17
Abstract: PURPOSE:To decrease number of transistors (TRs) by leading a light sensor output selected by a selection pulse of a drive circuit to the same output line so as to bring the product between an on-resistance of the switch and the light sensor capacitance to <=1/5 of the selection pulse width. CONSTITUTION:The drive circuit consists of master/slave shift registers 31, 32 and an inverter 33, a common terminal of polycrystalline silicon TFT switches Q1'-Q4' becomes an output signal line SIC3, the signal line is connected to a preamplifier with a low impedance and the level of the signal line reaches an apparent ground level. When selection pulses S1'-S4'- are impressed to the polycrystalline silicon TFT switches Q1'-Q4', an output signal is extracted to an output signal SIN3, a switching noise of a switch due to leading of the selection pulse is canceled because it is in opposite phase with the switching noise by the trailing of the selection pulse. Since the time constant is selected to <=1/5 of the clock pulse period, the time constant is as long as >=10 times, and high S/N is obtained with high speed read.
