Title: Exposure of fine pattern
Inventor: YAMADA AKIO
IPC: H01L21/027
Filed: 1989-07-14
Abstract: PURPOSE:To simply and surely align a beam with an optical axis by specifying data on a deflection amount which are given to a third deflection means and a fourth deflection means on the radiation side of a stencil mask. CONSTITUTION:The following are installed: a third deflection means 15c which directs a beam having passed through a mask 20 to an optical axis again; a fourth deflection means 25d which deflects the beam directed to the optical axis in such a way that the beam travels on the optical axis. Data on a deflection are given in such a way that individual deflection angles theta3, theta4 satisfy the following formulae: theta3=-theta1
-thetap
+alphatheta<b> and theta4=+theta1
+thetap
+betatheta<b> (in these formulae, theta1s is a deflection angle corresponding to D1
, thetap
 is that corresponding to Dp
 and theta<b> is that corresponding to D<b>; the deflection data D1
 is decided by a desired position on a mask sheet through which the beam is passed; the data Dp
, D<b> for deflection correction use are decided by the D1
; alpha and beta are constants). The beam which has been patterned by the mask sheet 20 is returned again on the optical axis to execute an exposure operation. Thereby, the beam which has passed the mask can again accurately be put on the optical axis, and a fine pattern can accurately and surely be exposed.

IPC: G11B7/09
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To provide an adjusting method of optical pickup device and a tracking error detecting device which can cancel the DC offset of tracking error signals in accordance with scattering, etc., of optical pickups. SOLUTION: The offset of a tracking error signal 10 is cancelled by subtracting the cancel(CSL) signal which is obtained by multiplying a correction Kw and adding/subtracting a correction Kwo from a push-pull(PP) signal. This time, first the tracking servo is operated to variably set the value of Kwo in the condition that the spot of light is not moved on the light detector so that the DC level of the PP signal becomes a reference voltage(Vc). Next, in the condition that the tracking servo is suspended and the above spot is moved by a given amount on the light detector, the DC level of the above PP signal is detected, and then the value of Kw is variably set so that the DC level of the PP signal accords with the above detected level.

Title: Pouch with improved discharging efficiency
Inventor: WATANABE TAKEHIKO
IPC: B65D33/38
Filed: 1993-07-23
Abstract: PURPOSE:To prevent the part where a spout is formed from buckling in pressing a pouch body with a hand and eliminate unsatisfactory discharging of contents, by providing a sealed face having a spout with a buckling prevention structure. CONSTITUTION:A pouch 1 has a size and a shape which meet an amount of liquid 2 to be filled, and has a content volume so that the width of a filling space normally becomes greater toward lower end and smaller toward a top sealed-face 4 in which a spout 3 is formed. An upturned sealed-part 4 is formed at least at one end of the sealed face 4 in which the spout 3 is formed. Thus, even when the upper part of the pouch expands by the grasp of the body of the pouch with a hand, the force of the contents acts in the direction of the upturned sealed-part 10 and force stretching the pouch 1 in the x-axis direction acts. This performs a function to prevent the occurrence of a wrinkle, and prevents buckling of the root of the spout due to wrinkling of the sealed face 4, therefore stable discharging is obtained.
