Title: Chain conveyor
Inventor: MINAZU OOTOSHI
IPC: B65G17/24
Filed: 1984-01-12
Abstract: PURPOSE:To aim at commonly using component parts for various kinds of chain conveyors, by providing such an arrangement that ring plates and guide rollers are supported onto a roller shaft on both sides of a carrier roller, and a spring is disposed between a chain link piece and the guide roller on each side of the carrier roller, so that contact pressure between members may be adjusted. CONSTITUTION:A substance to be conveyed is set on a carrier roller 7 and is conveyed by moving a chain 5. At this time, contact pressures between guide rollers 9, 9' and ring plates 8, 8', and between the ring plates 8, 8' and the carrier roller 7, which are obtained by spring washers 10, 10', are adjusted. For example, if the pressures are reduced, the guide rollers 9, 9' and the carrier roller 7 may be rotated independently from each other so that the substance is stopped or reversely moved. While if the contact pressure is slightly increased, the substance is conveyed at a speed equal to that of the chain 5. Further, if the contact pressure is further increased, the substance may be conveyed at a speed higher than that of the chain 5. With this arrangement, it is possible to aim at commonly using component parts for various kinds of chains and as well standardizing them, and as well it is possible to aim at rationalizing the assembly of chains.

Title: Focus detector
Inventor: AKASHI AKIRA
IPC: G02B7/28
Filed: 1987-01-12
Abstract: PURPOSE:To attain focus detection compensating the disablement of focus detection due to hand vibration on a telephoto lens and a far/near competition state of a wide angle lens by switching a focusing deciding range in accordance with the focal distance of a mounted photographing lens. CONSTITUTION:Photometric elements ST1-ST3 for AGC are respectively constituted of photodiodes to output a control signal SAGC through an conversional amplifier AAMP. An optical image formed on a sensor string SAA is also formed on the elements ST1-ST3 and the same optical image as that on the SAA is utilized for AGC. When a signal CAGC is 'H' (telephoto lens), AGC is attained in all the area, and when the signal CAGC is 'L' (wide angle lens), AGC is executed only on the center part. Consequently, focus detection compensating the disablement of focus detection due to hand vibration on the telephoto lens or the far/near competition state on the wide angle lens can be attained.

Abstract: PURPOSE:To simplify the construction by cleaning a guide roller interlocked in the low speed rotation range a belt-driven pulley installed concentrically with guide roller to be guided by a printing sheet and shutting the interlock in the high speed rotation range during printing. CONSTITUTION:A guide roller 3 rotatably installed on a rotary shaft 6 through a bearing 13 is rotated with running of a printing sheet to guide it. A belt pulley 5 is installed at one end of the rotary shaft 6 through another bearing 15 and driven by a sheet threading belt 4. A plurality of sprags 11c are arranged between an inner ring 11a fixed at the end face of the pulley 5 and an outer ring 11b fixed at the end face of roller 3. At the time of low speed rotation in order to clean the roller 3, the pulley 5 and roller 3 are interlocked with each other, and at the time of high speed rotation of roller 3 during printing, the pulley 5 is shut from interlocking to allow the printing sheet to rotate the roller 3.

Title: Sequential control circuit
Inventor: IWAKUNI SHIYUUZOU
IPC: G05B19/02
Filed: 1982-01-18
Abstract: PURPOSE:To prevent a filter effect from being spoiled without generating any individual frequency components by providing circuits for by-passing flip-flops corresponding to an objective system of sequential control supplied with a stop command. CONSTITUTION:At time Tx, when a pulse has a logical level 0, a bypass for an FF8 is formed and pulses B' and C' coincide with each other. Therefore, pulses C' and D' have logical levels 1 and 0 alternately and repeatedly. At this time, pulses H', I', and J' are outputs of AND between pulses B', C', and D', and E, F, and G, so when the E has the logical level 0, the H' has the logical level 0 without fail. Therefore, the signals H', I', and J' which are 120 deg. out of phase with one another when the E has the logical level 1 become signals I' and J' which are 180 deg. out of phase after the time Tx. Namely, when an optional number of output signals are intercepted, the remaining signals are generated automatically with an equal phase difference, preventing a component of individual frequency from appearing at a load side.

Inventor: UESUGI KENICHI
IPC: B21C51/00
Filed: 1986-01-16
Abstract: PURPOSE:To prevent a possible slip, by a method wherein a thin film like gas is interposed between a rotary part and a stationary part to support the rotary part with the gas so as to make the tracking property of a shape detecting roll better at acceleration or the like to provide synchronization between the speed of a steel plate and the circumferential velocity the of a roll without providing any auxiliary driver such as DC motor. CONSTITUTION:A high pressure air is sent into a hollow part of a hollow shaft 8 as bearing gas from an air feed port 10. This air is forced from a nozzle 11 into between the inner wall of a circular hole of a disc 2 and the outer wall of the follow shaft 8, where it is made a thin film to support a radial load of a roller 1. This enables the formation of a support surface for a load over the radial entire length of the roller 1. In addition, a part of high pressure air fed is forced into the end face of a roller via a bypass 12 thereby supporting thrust-direction load with air.

Title: Driving method for optical write type liquid crystal light valve
Inventor: YAMAMOTO SHUHEI
IPC: G02F1/135
Filed: 1990-01-12
Abstract: PURPOSE:To simplify configuration by always irradiating a light valve with a write beam and a read beam while impressing a rectangular wave voltage between the transparent electrodes of the light valve. CONSTITUTION:When an optical write type liquid crystal light valve 17 is continuously irradiated with the read beam while impressing a rectangular wave voltage 12, an electron positive hole pair is generated. Then, the electron is moved to a positive pole side and the positive hole is moved to a negative pole side. At such a time, when the valve is irradiated with the write beam, the electron positive hole pair is generated as well even near the surface of hydrogen amorphous silicon optical conductor on a write side and when the polarity of ferroelectric liquid crystal side is positive, namely, when the optical conductor side is negative, an electronic carrier is moved. Then, the impedance of the optical conductor at a part irradiated with the beam is lowered and the sufficient voltage is applied to a ferroelectric liquid crystal molecular. Afterwards, the state is inverted to a stable state inverse to the time of read beam irradiation and required information can be written. Thus, high resolution and high contrast can be obtained with the simple configuration and operation.
