IPC: G03F1/84
Filed: 1990-10-08
Abstract: PURPOSE:To surely measure the thin thickness of a mask for phase shift by calculating phase difference between light passing a part where a phase shifter is mounted and light passing a part where no phase shifter is mounted. CONSTITUTION:A reticle 10 is irradiated with illumination light L2 from a light source 1, and light quantity distribution obtained by receiving the light quantity of the projection image of the reticle 10 with a detector 16 is transferred to a processing circuit 18 as an electrical signal. At the processing circuit 18, the light quantity of the image of the mounting part 11b of the reticle 10 and that of the image of the non-mounting part 11a out of light quantity distribution signals are measured, respectively, and a light quantity ratio for them is found. The error of phase shift quantity by the phase shifter 11b can be decided based on an obtained light quantity ratio, the pattern size (the width (l) of chrome film 11c in this case) of a measured pattern, and the setting positions (de-focusing quantity) of the reticle 10 and the detector 16 in a direction of optical axis AX.

Title: Motion vector detector
Inventor: IWATA EIJI
IPC: H04N19/523
Filed: 1993-10-28
Abstract: PURPOSE:To reduce the memory capacity by comparing the quantity of difference absolute sums and storing selectively a minimum value of the difference absolute sum of entire picture element accuracy and a difference absolute sums thereabout to a difference absolute sum storage memory based on the comparison output. CONSTITUTION:A difference absolute sum outputted from a full picture element accuracy difference absolute sum arithmetic circuit 200 for each clock cycle is fed to a comparator 203, in which a minimum value of the difference absolute sum is obtained. Thus, the comparator 203 obtains a motion vector of the full picture element accuracy up to a current point of time and the vector is fed to a memory control circuit 204. The circuit 204 selectively stores the difference absolute sum taking a minimum value and the difference absolute sums thereabout to a memory 201. Thus, a memory capacity is reduced more than an object block number. Furthermore, a half picture element accuracy computing element 202 calculates the motion vector of half picture element accuracy from the difference absolute sum stored in the memory 201 when the motion vector of the full picture element accuracy is confirmed.

Title: Heat induction machine
Inventor: JIYATSUKU SUTERURINI
IPC: F25B29/00
Filed: 1984-12-21
Abstract: The machine for the more effective utilisation of heat uses a working substance which is a mixture of two pure substances with different boiling points. The machine has two columns (Cd,Cg) operating at different pressures. In the first column a quantity of heat (Qo) is supplied to the base of the column. This heat causes one of the components of the working substance to evaporate and flow to the upper part of the second similar column (Cg) which operates in a reverse manner. Quantities of heat are transferred between the two columns at different heights above the base of each column.

Title: Driving mechanism changeover device
Inventor: KATO MASAO
IPC: G11B15/675
Filed: 1990-10-11
Abstract: PURPOSE:To attain smooth changeover by providing an elastic member loaded between one end of a worm gear and a locking member, deformed when a prescribed force or over is exerted on the worm gear axially against the position restriction due to the locking member and allowing the axial movement of the worm gear to the changeover device. CONSTITUTION:A worm box 3 being a locking member formed in a channel shape is mounted on a worm shaft 1 freely slidably in the axial direction through two sides 3a, 3b opposite to each other, and a compression spring 4 is wound and mounted on an outer circumference of the worm shaft 1 between one end face of the worm gear 2 and one side 3a of the worm box 3. Thus, when the worm gear 2 moves in the axial direction with turning from one end to the other end of a moving range restricted by a locking member 3 and starts meshing with a driven member 7 and when the phase of the worm gear 2 and that of the gear of the driven member are not matched, the worm gear 2 is escaped in the axial direction by the compression of an elastic member 4 against the travelling locking member. Thus, wrong meshing of both the gears is prevented and smooth changeover of the drive mechanism is attained.

Title: Method for aligning reticle
Inventor: MORI YUICHIRO
IPC: G03F1/42
Filed: 1991-10-18
Abstract: PURPOSE:To accelerate aligning by carrying out the aligning according to first and second position alignment marks formed on a reticle board at a predetermined interval. CONSTITUTION:After two alignment marks 2, 3 are formed at a predetermined interval in a direction X on a reticle 1, a first alignment point is recognized, and they are aligned in directions X and Y with the point as a reference point. Then, a second alignment point existing in the direction Y at a predetermined interval in the direction X from the point is searched, and recognized. Thereafter, when a first alignment point is recognized as a reference point and a stage 5 is so moved as to scan vertical lines at a predetermined interval from the point in the direction X, since the second alignment point exists on the vertical line, it can be easily recognized. Thus, since the two alignment points can be recognized in a short time, an automation for aligning can be facilitated.
