Title: Copying machine provided with liquid crystal display
Inventor: TAKAHASHI KOZO
IPC: G02F1/13
Filed: 1989-01-25
Abstract: PURPOSE:To eliminate the reflection of light on the surface of a LCD and to obtain a copied image provided with sufficient contrasts by providing an exposure stopping means stopping the driving of an original exposing lamp in a screen copying mode when the LCD is mounted on the front surface of an original platen. CONSTITUTION:The original exposing lamp 24 is not driven in the screen copying mode when a LCD device 1 is mounted on the front surface of the original platen 5, the same as in an original copying mode after the operation of a printing switch PSW. Therefore, when an optical system device 27 is moved on the rear surface of the original platen in the direction of an arrow B, irradiating light from a light source 3, passes through a LCD 2 and the optical system device 27, and is distributed to a photosensitive drum 6: irradiating light from the original exposing lamp 24, is not distributed to the photosensitive drum 6. Thus, as for the photosensitive drum, the electric charge of the black part of an electrostatic latent image is not erased by reflecting light from the LCD, whereby the copied image of sharp contrasts can be obtained.

Title: Push bell input apparatus
Inventor: TSUDA TAKU
IPC: H01H9/18
Filed: 1989-01-25
Abstract: PURPOSE:To apply backup function to as many push bells as possible by producing a signal for identifying the first or second push bell when either of them is operated and producing a signal for identifying the first push bell by operation of the second bell when a switching bell is operated. CONSTITUTION:When each of push bells 27 to 29 is depressed, a signal corresponding to it is read out as it is by a control section 25 if a switching bell 31 is not depressed in an operation section 26. When the switching bell 31 is depressed, a signal corresponding to a stop bell 28 is produced by depressing a reverse bell 29, further signals corresponding to a start bell 27 and the reverse bell 29 are produced, respectively. When the switching bell 31 is depressed, each of the push bells 27 to 29 of a group 30 of push bells in usual use is shifted by one. Thus, even if one push bell is failed when actually used, another push bell can respond to that by depressing the switching bell 31. Therefore, backup function is obtained.

Title: Driving method for liquid crystal display device
Inventor: TANAKA HIDEO
IPC: G02F1/133
Filed: 1989-01-25
Abstract: PURPOSE:To obtain an LCD which has a small image flicker by varying a scanning signal potential in synchronism with the inversion of an image signal and not varying the scanning signal, the image signal, and the potential difference between common potentials, at every field. CONSTITUTION:The driving waveform of the LCD is so set that the image signal 2 is written in picture elements of an (N)th row with a scanning pulse 41 when the polarity is positive or with a scanning pulse 42 when negative and the pulses 41 and 42 differ in peak height. Further, the potential of the part where none of pulses of the scanning signal 3 is applied is made different according to the polarity of the image signal 2. In this constitution, the image signal 2 is inputted from a drain electrode through a TFT for the period of the scanning pulse 41 when the image signal 2 is in a positive to hold charges in liquid crystal. This driving waveform makes scanning pulses that the TFT senses invariably constant irrelevantly to the positive and negative fields to reduce the flickering of the LCD.

Title: Heat transfer tube
Inventor: KAMEOKA HIDEMITSU
IPC: F25B39/00
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To increase heat transfer area, to vigorously disorder an interface of absorption liquid film at a surface of the tube, and to improve heat transfer characteristics by forming many grooves of a trapezoidal section on an outer periphery of the tube in parallel and setting a depth and bottom width of the groove to specific ranges.

The depth of the groove is specified at 0.2 to 1.0mm to obtain an effect due to interface disturbance of a liquid film. Thus, a heat transfer area of the inner surface of the tube can be increased, and since the interface disturbance is generated in material to be cooled or cooling water flowing in the tube, heat transfer characteristics can be further improved.

Title: Printer
Inventor: KOBAYASHI KAZUYOSHI
IPC: B41L13/04
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent skew of a master by automatically correcting a course of the master straightly. SOLUTION: A thermal head 10 is relatively brought into contact with and separated from a platen roller 9 plural times during a period for conveying a master 1 at a predetermined distance toward a plate cylinder 2 so that the roller 9 is rotated only when the master 1 on the roller 9 is brought into pressure contact with a thermal head 10. Accordingly, each time when the head 10 is separated from the roller 9, the master 1 is released from its holding state, and each time of this release, a course can be slightly effectively corrected by strength of stiffness of the master 1. Further, since the master 1 can be conveyed only when the master 1 is uniformly sandwiched between the roller 9 and the head 10 in the entire area of its width direction, frictional pressure applied to the master 1 at the time of conveying can be made uniform and hence the master 1 can be conveyed straightly.

Title: Exposure by electron rays
Inventor: MIYAUCHI SAKAE
IPC: H01J37/302
Filed: 1981-02-05
Abstract: PURPOSE:To avoid a repeated exposure to an overlapped portion by a method wherein a figure is converted to a collection of ridge-point expression data having no overlapped portion while holding the shape of a drawing figure when the figure having ridge-point is drawn by an electron ray exposing method and thereafter it is exposed to light. CONSTITUTION:An electron ray exposure unit comprises CPU1, bit matrix development controller 2, memory controller 3, bit matrix 4, drawing data registering memory 5 and registers r1-r7. In this way, a command signal is transmitted from the CPU1 to the controller 3, thereby clearing the memory contents on the matrix 4. Subsequently, a standard figure having an angle point in the CPU1 is divided into a plurality of minute figures having no overlapped ridge-points while maintaining the basic figure, while a start signal is applied to the controller 2 and the output thereof is developed to the matrix 4. In this case, the registers r1-r7 serve to judge the existence of the overlapping, and if the overlapping is detected, they store the ridge-point expressing data to the memory 5 after newly sectioning the figure.

Title: Production of color filter
Inventor: MORI YASUKI
IPC: G02B5/20
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To make it possible to form fine patterns of multicolors with good workability, high accuracy and good yield by subjecting colored photosensitive resin layers to exposure in patterns, then reexposing only the apertures and heating the resin layers to increase the film thickness of the apertures. SOLUTION: The colored photosensitive resin layer 3 of a first color is laminated on a transparent substrate 2 in such a manner that the resin layer 3 does not enter between black matrixes 1 (b). After the resin layer is exposed to a pattern form by using a photomask 6 (c), both the photoset parts and unset parts are melted and softened by heating and are brought into tight contact with the substrate 2 (d). Only the apertures are then reexposed (e) and are heated by which the unreacted monomers are diffused into the reexposed parts, are migrated from the unexposed parts and are polymerized. The film thickness, therefore, increases in the reexposed parts and decreases in the other parts (f). The base film 4 is peeled at this time and the resin layer is developed (h).  The colored photosensitive resin layer 8 of a second color is then stuck (i) and further, a third color is stuck thereto after the operation similar to the first color.
