Title: Liquid crystal color filter
Inventor: OTSUKA SHOJI
IPC: G09F9/00
Filed: 1990-04-19
Abstract: PURPOSE:To improve a display position by adopting a configuration such that the arrangement of three primary color filters for red, green and blue colors is deviated in the vertical direction with respect to the horizontal direction. CONSTITUTION:The arrangement of three primary color filters for red, green and blue colors is deviated in the vertical direction with respect to the horizontal direction. Thus, adjacent lines of separate lines 11,12,13,...22 are parted in the vertical direction and not on a line in the horizontal line. Then the deviation is selected to be, e.g. 1/2 color filter, and the liquid crystal cell is arranged corresponding to the color filter, and in the case of scanning, a relevant liquid crystal cell is activated so that every other color filter in the horizontal direction is valid. Since separate lines in the horizontal direction to separate adjacent color filters in the vertical direction are dispersed, the separate lines are not eminent on the entire display screen. Thus, the position of liquid crystal display is improved.

Title: Axial flow fluid turbine
Inventor: OCHIAI HIROSHI
IPC: F01D3/04
Filed: 1984-05-23
Abstract: PURPOSE:To reduce the axial thrust by providing a pressure equalizing chamber at the end surface of a generator on the outlet side in a turbine body and communicating the pressure equalizing chamber through a balanced pressure passage with the inlet side in the turbine body so as to generate in the pressure equalizing chamber a thrust directed opposite to the axial thrust of a turbine wheel. CONSTITUTION:Fluid under high pressure flows through an inlet port 3, and a lift generated by a moving blade 1C rotates a generator 5 through a turbine wheel 1. Then, the pressure of the fluid under high pressure is decreased, when it reaches an outlet port 4, and at this time, the axial force component of the lift causes the turbine wheel 1 to generate an axial thrust directed from the inlet port 3 to the outlet port 4. As a balanced pressure passage 10 serves to complete communication between a space 2A defined on the inlet side in the turbine body and a pressure equalizing chamber 7, a pressure-bearing disc 9 generates a thrust directed opposite to the above-mentioned axial thrust. Therefore, if the area of the pressure-bearing disc 9 is properly set, the axial thrust of the turbine wheel 1 can be kept in an equilibrium condition or reduced.

Title: Image forming device
Inventor: TAKAHASHI KAZUHIKO
IPC: G03G21/14
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To make the time required for processing able to be shortened when an image is intermittently formed by making the start of a polygon mirror driving motor independent of the start of a photoreceptor drum driving motor. SOLUTION: When the photoreceptor drum is started to be rotated, the photoreceptor drum driving motor is driven when a throw-up signal being independent of the polygon mirror driving motor as a reference pulse signal. Thus, when the image is intermittently formed, only the photoreceptor drum driving motor can be intermittently driven and stopped while the polygon mirror driving motor is continuously driven. When phase difference between a scanning start signal and the throw-up signal becomes small to such an extent that the step out of the photorecetor drum driving motor can be evaded after the rotational frequency of the photoreceptor is stabilized (time T1), the driving of the photoreceptor drum driving motor is switched to the driving executed based on the scanning start signal from the driving executed based on the throw-up signal.

Filed: 1994-05-19
Abstract: PURPOSE:To switch the resolution in the subscanning direction of pictures corresponding to an output means such as a monitor or the like by a stuck image pickup device by switching whether or not to add picture signals. CONSTITUTION:By picture element mixing control signals from a system controller 18, signals S1' and S2' from a TG part 11 and output signals from a mask part 16 are selected by a changeover switch 17 and switched and outputted signals S1 and S2 are supplied to an addition part 15. That is, control is performed so that picture elements are mixed and reading is performed in an interlace system because flickers appear visually and the pictures are difficult to see when the information of the high resolution of a total scanning line number level is supplied to the display system of the interlace system and the picture elements are not mixed and the reading is performed in a non-interlace system because the pictures are blurred in the direction when the information of the low resolution in the subscanning direction is supplied to the non-interlace display system inversely. Thus, the resolution in the subscanning direction of the pictures can be switched corresponding to the output means such as the monitor or the like and visually improved characteristics can be obtained.

The ink image is further transferred onto a medium to be recorded 7 passing through an impression cylinder 6 rotating in an arrow dirrection D in contact with the blanket cylinder 5. An image 8 corresponding to the ink image is formed. In the ink used at this time, a liquid dispersion medium and a pH buffer are incorporated as basic elements. The liquid dispersion medium basically has gas generation characteristics by an electrolysis, i.e. adhesion control characteristics. The pH buffer in use is soluble in the liquid dispersion medium and has a buffer action in the water solution in a 1 - 14 pH range.
