Title: Liquid crystal display device
Inventor: OKAMOTO SHINICHI
IPC: G02F1/141
Filed: 1988-12-13
Abstract: PURPOSE:To improve contrast by impressing electric fields to respective liquid crystal panels in such a manner that the molecular axes of ferroelectric liquid crystals and dichromatic dyes are respectively parallel with each other between the two liquid crystal panels in a bright state and intersect orthogonally with each other in a dark state. CONSTITUTION:A panel unit 10 is constituted of the liquid crystal panels 10A, 10B. An electric field impressing means 20 impresses the electric fields to the respective ferroelectric liquid crystals 14a, 14b. The molecular axes of the ferroelectric liquid crystal 14b and the dichromatic dye 15b are perpendicular to the light component transmitted through the liquid crystal panel 10A and, therefore, the light transmitted through the liquid crystal panel 10A transmits the liquid crystal panel 10B without attenuating in the bright state. The molecular axes of the ferroelectric liquid crystal 14b and the dichromatic dye 15b are parallel with the light component transmitted through the liquid crystal panel 10A and, therefore, the light transmitted through the liquid crystal panel 10A is nearly entirely absorbed by the liquid crystal panel 10B. The contrast is improved in this way.

Inventor: NAKAMURA KATSUSHIGE
IPC: F16H25/20
Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To enable positioning with very high accuracy while the structure is simple by providing two sets of rectilinear motion mechanisms formed by spirally advancing a moving nut on a feed bolt rotated by external driving force, and combining the mechanisms to constitute a positioning mechanism. SOLUTION: In the case of adjusting a focal point of an objective lens 51 of measuring optical instruments in a finite range, a clutch 30 is turned on to rotate a driving gear 48 by a motor, and a first gear 18 and a second gear 28 meshing with the gear 48 are rotated in the reverse direction by equal angle at a time. The rotation is transmitted to feed bolts 11, 12, thereby moving moving nuts 12, 22 which are screw-engaged with the feed bolts 11, 12 and opposite to each other in the feed direction in the opposite directions. In this case, the screw pitch of the second feed bolt 21 is set a little smaller than that of the first feed bolt 11, whereby the second moving nut 22 is moved for a difference in travel between both moving nuts 12, 22, thereby fine-adjusting the position of the objective lens 51 can be conducted.

Abstract: PROBLEM TO BE SOLVED: To make a black part hardly visible by using the character of visual sensation of a human being when the black part appears on a screen due to reason of a hardware. SOLUTION: This picture signal processor is provided with a specifying part 1 which obtains the position of a black line appearing on the screen and specifies the ambient range of the line, a setting circuit 2 in which a rate with which the luminance of a picture signal in the ambient range of the black line specified in the part 1 is to be raised is set and a processing part 4 which raises the luminance of the picture signal in the ambient range of the black line higher than that of the picture signal with which the signal is to be originally displayed in accordance with the rate set in the circuit 2 and outputs it.  Thus, this black line is made hardly visible by using the character of visual sensation of the human being by making the picture signal brighter while raising the ambient luminance of the black line in this manner and the quality of a picture is enhanced by an amount equivalent to the increased luminance.

Filed: 1987-12-15
Abstract: PURPOSE:To prevent the scatter of toner and the mixture of toner by impressing a voltage obtained by synthesizing a common AC voltage and a voltage selected from plural DC voltages on a developer carrier. CONSTITUTION:After the AC voltage oscillated by an oscillation circuit 10 is boosted to a specified voltage in a boosting circuit 11, the voltages outputted from different output terminals are smoothed in smoothing circuits 12 and 13 and outputted as DC components Va and Vb(<Va). The AC voltage oscillated by an oscillation circuit 14 is also boosted in a boosting circuit 15 and the outputted AC voltage Vac is superposed on the Va and Vb. Therefore, V1=Va+ Vac, V2=Vb+Vac are obtained. By controlling the bias of the developer carrier 1 with a switch 33 through a sleeve 31 according to the two voltages, the scatter and the mixture of toner can be prevented.

Title: Thermal transfer/recording device and ink ribbon cassette using the same device
Inventor: SUGIMOTO YUKIHIKO
IPC: B41J35/22
Filed: 1989-12-04
Abstract: PURPOSE:To determine the position of an ink ribbon correctly by providing a detection sensor which detects the movement of a required ink ribbon cassette to a position corresponding to a recording head and a control part which controls a lift base on detection results. CONSTITUTION:A lift 27 is activated by a command for recording to select a required color ink ribbon for printing. A vertical position detection sensor 82 detects the movement of a desired ink ribbon cassette 24 to a position corresponding to a recording head 22. The position is detected by projecting a light to a reflecting plate 47 from the vertical position detection sensor 82 and interpreting whether or not the desired cassette is in place through the reflecting beam. A control part 83 controls the drive of the lift 27 based on the detected results. As a vertical position can be determined with a ribbon cassette 24 given as a reference, the cumulative error of the cam of the lift 27 of the cumulative tolerance of the thickness of the cassette 24 can be ignored. In addition, the relationship between the ribbon position and the energized recording head 22 is made uniform at each step. Thus an offset position at each step can be corrected.
