Title: Color electrophotographic printing device and method
Inventor: AOYAMA KAZUMI
IPC: G03G21/14
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To simplify a color electrophotographic printing device and method and to achieve cost reduction by making the distance between primary and secondary transfer parts on an intermediate transfer element longer than the length of a storage medium in the feed direction. SOLUTION: The distance Ltb between a primary transfer part 14 and a secondary transfer part 15 on a transfer belt 6 is made greater than the length Lohp of an OHP sheet 7 along its feed direction. After primary transfer of an image 10-a of the last color on the transfer belt 6 from a photoconductor belt 5, a speed control part 16 immediately makes the speed of the transfer belt 16 as slow as the speed of a fuser 8. In this case, since the distance Ltb between the primary transfer part 14 from the photoconductor belt 5 and the secondary transfer part 15 transferring images to a storage medium is longer than the distance Lohp of the OHP sheet 7 along the feed direction, an image 10-b is still located between the primary transfer part 14 and the secondary transfer part 15 on the transfer belt 6.  Therefore, the OHP sheet 7 is fed to the secondary transfer part 15 of the transfer belt 6 at a slow speed and is transferred without the loss of time such as waiting time.

Title: Transfer system
Inventor: FUKUDA TAKAFUMI
Filed: 1989-12-28
Abstract: PURPOSE:To shorten a transfer operation time by using a memory card stored plural transfer data. CONSTITUTION:The transfer data D in the memory card 1 are successively read out from a memory means 4 and displayed on a memory card display means 5 by a retrieving means 6 and the card 1 is inserted into an automatic teller machine 2 with a transfer function. In the machine 2, the card 1 is sucked by a sucking means 11 and the data D displayed on the means 5 are read out from the means 4 by a reading means 9. The machine 2 checks the data D from the card 1, and when the data D are correct, a guide picture is displayed on a display means 10 in the machine 2. A customer inputs additional data by an input means 8 in accordance with the instruction of the screen of the means 10 to execute transfer operation. If the data D are not correct, the machine 2 displays a message such as 'memory card transfer data reinput' on the means 10 to instruct reoperation. After executing correct operation, the machine 2 discharges the card 1 by a discharging means 12. Thus, the operation time can be shortened by using the card which previously stored plural transfer data.

Title: Slave pattern information storage circuit
Inventor: MIYAUCHI MASAYOSHI
IPC: H04N5/265
Filed: 1989-12-29
Abstract: PURPOSE:To prevent lateral stripe and missing of lateral lines by applying N-line of averaging processing and outputting a slave pattern video data when the data is outputted one per N horizontal scanning lines. CONSTITUTION:A changeover circuit 11 receives a slave pattern video output DT1 and the output per each horizontal scanning line is outputted cyclicly from output terminals Q1, Q2, Q3. Line memories 121, 122 latch tentatively a data outputted from the output terminals Q1, Q2 and outputs the data based on a control signal. An averaging processing circuit 13 applies averaging processing to a data outputted from the line memories 121, 122 and the data outputted from the output terminal Q3 of the switching circuit 11 and outputs the result to the line memory 2. Thus, all of three lines of information sets are included in slave pattern information outputted in the rate of one per three horizontal scanning lines from an N:1 processing circuit 1. Thus, occurrence of lateral stripes and missing of lateral lines of a character or the like are prevented.

Title: Semiconductor memory
Inventor: ORITA NOBUYUKI
IPC: G11C17/12
Filed: 1989-12-29
Abstract: PURPOSE:To increase a read speed by discharging digit lines other than a digit line selected for the fall of a word line at the time of reading out a memory cell. CONSTITUTION:A digit line control circuit is provided which detects the word line selection of an X decoder and discharges non-selected precharged digit lines simultaneously with detection. Since a word line X1 and digit lines D2, D3 to Dm intersect each other in many positions in this case, many small parasitic capacities exist. Since these parasitic capacities have a very large value in total, the fall speed of a select signal X1 is increased by capacity coupling when non-selected digit lines are quickly discharged simultaneously with the fall of the select signal X1. Thus, the read speed of a transistor Q11 as the memory cell is increased.

Title: Three-dimensional coordinate measuring equipment
Inventor: SUZUKI YASUO
IPC: G01B21/20
Filed: 1993-12-15
Abstract: PURPOSE:To prevent the danger of an operator at the time of the exchanging operation of measuring probes and the damage of the measuring probes by providing a measuring-probe exchanging-operation detecting means and a control means stopping a driving means. CONSTITUTION:When an operator opens a door 22 for a storage chamber 21 when a measuring probe 14 is exchanged, a door-opening signal displaying the start of exchanging operation is transmitted over controllers from a 20 (a measuring-probe exchanging-operation detecting means). The controllers (a control means and a signal processing section) control the operation of an X-axis carriage 11, struts 6, 7 and a Z-axis guide 13 through a motor (a driving means). Consequently, when pre-operation (the opening and closing of the door 22) is detected, the X-axis carriage 11, the struts 6, 7 and the Z-axis guide 13 are stopped, thus avoiding a danger applied to the operator due to the movement of the guide 13, etc., when the probe 14 is exchanged. When the probe 14 is exchanged, power, a signal and the supply of compressed air are interrupted, thus preventing the damage of the probe 14 due to overcurrents and an air current at high pressure.

Title: Production of color filter and color liquid crystal display element
Inventor: OGURA MASAYOSHI
IPC: G02F1/1335
Filed: 1997-12-12
Abstract: PROBLEM TO BE SOLVED: To produce a color filter having almost uniform film thickness by including a second exposure process for exposing a photosensitive material again after the photosensitive material is developed and before baked. SOLUTION: After development, the photosensitive material is irradiated with UV rays under specified exposure conditions for post-exposure (second exposure process) of a film 3r of a color phase R (process c). After the post- exposure, the film is subjected to post-baking by using an oven or the like to thermally polymerize and harden the film 3r of the color phase R (process d). By forming a color filter layer 3 in this procedure, the difference in film thickness of the color filter layer 3 is controlled to <=0.1 μm. Namely, by controlling the quantity of exposure light in the second exposure process for exposing again the photosensitive material after development and baking, spreading of the area where photopolymn. is completed in the film thickness direction in the photosensitive material can be controlled.  Therefore, reduction in film thickness after baking can be controlled and the film thickness is made uniform.
