Title: Formation of resist pattern
Inventor: FUKUZAWA TAKESHI
IPC: G03C5/00
Filed: 1987-02-25
Abstract: PURPOSE:To obtain a method having excellent reproducibility and dimensional accuracy by coating a wafer with positive type resist, giving a focus value larger than an optimum value, aligning a focal point under a resist layer to expose it, and forming an inversely tapered shape resist pattern. CONSTITUTION:A wafer 1 is coated with positive type resist, a focus value is increased larger than an optimum value to align a focus under the resist layer to be exposed, thereby forming an inversely tapered shape resist pattern 2. That is, the focus value is slightly increased for an optimum exposure time, i.e., the focus is slightly moved toward the lower part of the resist to be exposed. Accordingly, when a forming method for the pattern is used, an ideal metal pattern can be formed by a lifting OFF method in simple steps, and an ion-implanted region of concentration distribution can be formed in simple steps.

Title: Belt type continuously variable transmission system
Inventor: TAMAGAWA TAKAO
IPC: F16H9/10
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To smoothly perform the speed change by a belt type continuously variable transmission system by taking a balance between the force for eccentrically displacing a power transmission ring and the force for energizing the power transmission ring to the concentrical side. SOLUTION: A hydraulic cylinder 110 is operated, and the belt tensile force by this operation is added to the tensile force given to a belt 102 by an elastic member 134 of a tensioner. In the case where the resultant force is larger than the force of an energizing member built in a variable diameter pulley 107 and for energizing a power transmission ring to the concentrical position, the power transmission ring is displaced so as to be eccentrically positioned in relation to the rotary axis K, and a desirable transmission ratio is obtained. In the case where the hydraulic cylinder 110 is not operated, since the force of the energizing member for energizing the power transmission ring to the concentrical position is larger than the force of the elastic member 134 for displacing the power transmission ring, the concentrical condition is maintained.  Balance of the force through the belt 102 is utilized so as to smoothly perform the speed change.

Filed: 1987-02-27
Abstract: PURPOSE:To alleviate the abrupt change of a control current when an accelerating state is transferred to a decelerating state by adding an amplitude controller for limiting a driving current at the time of acceleration. CONSTITUTION:A difference counter 2 counts down a distance from the present position of a head to a target track by the output of a track loss detector 11.

IPC: G03B33/12
Filed: 1988-02-25
Abstract: PURPOSE:To make bright lines inconspicuous by providing the halved dichroic mirrors of a color separating means in a state where the mirrors are dislocated from each other. CONSTITUTION:A color separating means 47 is provided with a plane plate type red-reflecting dichroic mirror 62 and halved plane plate type blue-reflecting dichroic mirrors 63 and 64 by making them cross at right angles in the shape of X and being dislocated from each other while their dichroic multilayered film surfaces 65 and 66 are parallel with each other. In other words, the color separating means 47 is set in such a state that, when the means 47 is viewed from the direction, from which green light comes out along the incident light, cross cut faces 67 and 68 can overlap. Therefore, when the pupil of a projection lens 56 is viewed, the dark lines corresponding to the intersecting section 76 of the color separating means 47 become narrower and the conspicuousness of bright lines is improved. Moreover, regarding the blue light, the problem of bright lines can be ignored since the optical path from the intersecting section 76 of a light valve 54 is long.
