Title: Method and device for manufacturing color filter and color filter substrate
Inventor: TANIDA TAKAHIKO
IPC: B41J2/175
Filed: 2001-04-20
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for manufacturing a color filter for improving efficiency of an area on which ink is discharged in a preliminary discharge region, besides increasing total possible discharge amount in the preliminary discharge region with a definite area and further preventing a defective product and a color filter substrate. SOLUTION: A dummy cell 5 in the preliminary discharge region 4 is formed by surrounding an area larger than that of a cell 3 in an effective pixel region 2 and the preliminary discharge is carried out on the dummy cell 5 from an inkjet head. Thereby the efficiency of the area on which the ink 8 is discharged in the preliminary discharge region 4 is improved and the total possible discharge amount in the preliminary discharge region 4 with the definite area is increased. Also because the dummy cell 5 is surrounded by a black matrix 6, the ink 8 does not flow out to the side of the effective pixel region 2.

Title: Friction wheel continuously variable transmission
Inventor: KOYAMA TAKAO
IPC: F16H15/52
Filed: 2001-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a friction wheel continuously variable transmission for reducing cost by using a disc having an expensive cone face only on one side of an output side and an input side. SOLUTION: Rotation to an input shaft 1 reaches a friction wheel support shaft 2 via gears 3 and 4 and subsequently reaches to a power roller 8 via a loading cam 9. The power roller 8 imparts rotational force in a direction, corresponding to an output disc 12 in a contact part with an output disc recessed type cone face 12a and extracts rotation out of the output disc 12 via an output shaft 11. The loading cam 9 generates thrust, according to transmission torque and presses the power roller 8 on the output disc recessed type cone face 12a to enable transmission. The speed change ratio between the input shaft 1 and output shaft 11 is determined as (B/A)×(C/D) by a fixed gear ratio C/D between the gears 3 and 4 and a rotation transmission ratio B/A between the output disc 12 and the friction wheel support shaft 2, and the speed change ratio can be controlled by B.  When a speed change arm 6 is located at an oscillating position, corresponding to a command speed change ratio by a varying speed motor 15 via a speed change gear 14 and the shaft 2 is located at a corresponding turning position, the B becomes a value in response to the command speed change ratio and the speed change ratio can be made as the command speed change ratio.
