Title: Manufacture of thin type printed board
Inventor: TSURUOKA KOICHI
IPC: H05K3/00
Filed: 1988-06-15
Abstract: PURPOSE:To prevent a substrate from crawling up onto a roller or being rolled inbetween rollers by providing a part whose thickness is thicker than that of other part, at the end part in the transfer direction of a printed board. CONSTITUTION:A part whose thickness is thicker than that of other part is provided at the end part in the transfer direction of a thin type printed board 1. The length 8 in the transfer direction of the end part thicker in thickness is made longer than the interval 7 between fellow rollers arranged in the transfer direction. By thickening the end part this way beforehand, even if it is subjected to ejection of etching liquid 6 during transfer by a roller in an etching process, it can stand the ejection pressure of the etching liquid 6, and it never bends vertically, Hereby, the regular transfer passage can be maintained, and it can prevent such a trouble that the printed board 1 is released from gap between fellow rollers neighboring in the transfer direction and the production process stops or that the printed board 1 itself bends.

IPC: F16C32/06
Filed: 1985-07-05
Abstract: PURPOSE:To ensure the stability of bearing rigidity by cantilever-supporting a moving part interposed between the first and the second recesses with prescribed clearances to a valve body by means of two sheets of plate springs and communicating the first and the second recesses with the first and the second pocket parts of a housing. CONSTITUTION:A body 21 is supported by bearing housings 24a and 24b, and the pressurizing fluid flows out from the clearances H1 and H2 between the body 21 and lands 25a, 25b. The first and the second recesses 36 and 37 in the flanges 30 and 31 of the valve body 29 of a control throttle valve 28 are communicated with the first and the second pockets 22 and 23 in the bearing housings 24a and 24b respectively. If a load DELTAW acts on the body 21, the clearance H2 becomes larger than the clearance H1, and the pressure P1 at the recess 36 becomes larger than the pressure P2 at the recess 37 to bend plate springs 41, 42 so that a moving part 40 performs a parallel displacement. And, if the clearance X1 increases, the quantity of pressurized fluid to the pocket 22 increases, and a large differential pressure change for a load is generated even for a slight change in the clearances H1 and H2, and accordingly the bearing rigidity is enhanced.
