Title: Method and device for image correction
Inventor: SAKAI YOSHIHIRO
IPC: G03G15/04
Filed: 1989-07-17
Abstract: PURPOSE:To readily correct an original sheet in a short time by placing a reversible heat-sensitive sheet which shifts to a transparent state from a cloudy state and vice versa on the original sheet and switching a part that is not to be copied to an opaque, cloudy state by a heating head. CONSTITUTION:The reversible heat-sensitive sheet 2 which shifts to a transparent state from a cloudy state and vice versa is placed on the original sheet 1, and the heating head 4 switches the part not to be copied to an opaque, cloudy state from a transparent state. The reversible heat-sensitive recording material is known as thermochromic material which selectively realizes a transparent or cloudy state at a room temperature due to the difference between heating temperatures, and which is composed of a matrix material made of thermoplastic resin and an organic low- polymer substance dispersed in the matrix material. Consequently, the original contents can be corrected in a short time instead of altering the original itself, without waste and trouble.

Title: Dynamic pressure fluid bearing device
Inventor: MURAKAMI HIDENORI
IPC: F16C17/10
Filed: 1986-08-05
Abstract: PURPOSE:To decrease the rotating speed to start floating in the thrust direction and shorten the time to attain the stationary flotation quantity by providing a pressure regulating valve on a flow hole communicating a pressure chamber formed between the end face of a shaft and the thrust bearing face to the outside of a housing. CONSTITUTION:A flow hole 11 is provided at the center of the thrust bearing bottom 3 of a housing 1, and a pressure regulating ball 12 is brought into contact with it. When the housing 1 is rotated, the housing 1 is floated by the action of the dynamic pressure generating groove 5 of a shaft 4. During the low-speed rotation, the ball 4 is kept in contact with the flow hole 11, the fluid does not flow out, and the housing 1 is floated at a lower rotating speed. When the rotating speed is increased and the dynamic pressure is made larger than the energizing force of the ball 12, the fluid flows out, and the flotation quantity of the housing 1 becomes a fixed value. Therefore, the rotating speed to start floating is decreased and the time to attain the stationary flotation quantity is shortened by regulating the pre-load by the ball 12.

Title: Paper leaf sorting device
Inventor: ISHIGURO AKITO
IPC: B65H3/06
Filed: 1982-10-20
Abstract: PURPOSE:To enable leaves of paper to repair in themselves their abnormal sorting caused by a wedge phenomenon by respectively driving a picking up means in the paper sending-out direction and a gating means in the paper delivery direction at the time of paper feed means stoppage. CONSTITUTION:When leaves of paper 1 are set, and a solenoid 9 is excited to suck a movable body 9a without driving a feed roller 7, a driving arm 11 moves in the arrow (a) direction. Then, rotary shafts 3a, 8a, a pick up roller 3, and a gate roller 8 are respectively turned in the arrow directions (b), (c) via auxiliary arms 12, 13 and oneway clutches 16, 17 pivotted round the derivery arm 11. Hereby, a wedge phenomenon of the leaves of paper 1 is corrected. On the contrary, when the solenoid 9 is deenergized, the driving arm 11 is returned back to a stopper 20 position by means of a tensile spring 19. However, the leaves of paper do not return back to an original position since the above-mentioned respective clutches 16, 17 are idly slided.

IPC: H04L27/00
Filed: 1986-08-05
Abstract: PURPOSE:To form encoding low in redundancy, and a modulating and demodulating circuit by adding an error correcting code only to a subset having a short distance between signals. CONSTITUTION:A speed conversion circuit 1 makes four continuous binary data into data blocks l in length and separates two groups of (a1, a2-ak) and (a11, a12, a13) from a signal D1 having the shortest distance between subsets. Three-bit data a11, a12 and a13 are added to other data D2, D3 and D4 one by one. Data length should be l+1 when an encoder 2 adds four bit parities P1-P4 to a1-ak included in the data D1 and when data a11, a12 and a13 are added to the data D2-D4 one by one. Thus, since the amount of error correcting redundant bits can be minimized to lower redundancy.

Abstract: PROBLEM TO BE SOLVED: To reduce an amount of operation and to make a circuit scale of a data delayer provided between operation units smaller to a considerable extent by performing block matching with regard to all prediction block candidates in a search area, obtaining a prediction block matching most to an encoding block and detecting a motion vector.

On the other hand, a reference pixel value is once accumulated in a reference memory 2 and inputted to reference registers 4 and 5. By this reference pixel input, the reference pixels corresponding to all the prediction block candidates within a range of a horizontal direction -4 to +3 and a vertical direction -4 to +3 are inputted. In this way, the result of PE 6 is accumulation added at a PE 7 furthermore, and a sum of difference absolute value (AE) of the encoding blocks and the prediction block candidate is outputted from the PE 7. Then, a motion vector is decided with the prediction block candidate having the minimum value out of an amount of error outputting the final step PE as the prediction block.

Title: Spatial optical modulating device
Inventor: IGASAKI YASUNORI
IPC: G02F1/133
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To provide the spatial optical modulating device which is simple in structure and easily controlled and has fast response. SOLUTION: An optical modulation layer 17 consisting of an a-Si photoconductive layer 14 varying in resistance with write light intensity and liquid crystal modulating read light is arranged between ITOs 13 and 20 applied with a driving voltage of 5.1 V lower than a conventional driving voltage from a driving device 2. The incidence of the write light decreases the resistance of the photoconductive layer 14 and then the tilt state of liquid crystal molecules of the optical modulation layer 17 changes to modulate the read light. For erasure, the tilt state of the liquid crystal molecules of the optical modulation 17 is put back to the original state by natural migration, but a non-modulation state corresponds to a halfway state of the natural migration, so the time up to the return to the state is shortened to improve the response.  Further, weak irradiating write light is made present even when there is no write image to hold the modulation quantity of the read write at 0.
