Patent JP-H0293306-A (JP)
Title: Method for alignment
Inventor: KAMON KAZUYA
IPC: G01B11/00
Filed: 1988-09-29
Abstract: PURPOSE:To effect alignment in longitudinal, lateral and rotational directions with a single alignment mark by constituting said alignment mark into a diffraction grating not possessing translational symmetry such as a Fibonacci grating. CONSTITUTION:A Fibonacci grating 10 is formed on a wafer 50. An incident light 52 is diffracted by this grating 10, and the diffracted light 11 enters a two-dimensional photoreceptor device 12 and forms a light receiving area 13. Alignment in longitudinal, lateral and rotational directions is done by detecting a position where the strength of the diffracted light 11 incident upon the photoreceptor device 12 is largest. More specifically, if the wafer 50 is shifted in a direction shown by an arrow 56, a position where the integral strength of the diffracted light 11 becomes maximum may be obtained. If the wafer 50 is rotated in a direction shown by an arrow 14, the diffracted light area 13 is inclined. Therefore, the wafer 50 should be rotated in a direction to correct the inclination. Thus, the alignment in longitudinal, lateral and rotational directions can be achieved by a single alignment mark.

Title: Applicator with valve
Inventor: WADA NAOKI
IPC: A45D34/00
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To realize the sure enclosing properties of a valve mechanism inside a front shaft by a method wherein a seat part is formed on an annular projecting part integrally formed rear at the rear end of the tip hole of the front shaft. SOLUTION: An annular projecting part 9 is formed near the rear end of the tip hole 4b of a front shaft integrally with the front shaft. A seat part 9a abutting against the valve part 6b of a valve body 6 is formed near the apex of this annular projecting part 9. The valve part 6b and the seat part 9a close a valve through the forward energization of the valve body 6 for urging, resulting in ensuring the enclosing properties of the valve. The valve has a valve mechanism, which opens the valve by releasing the urging through the retreating of the valve body 6. Further, the projecting part 9 must be annular, since the seat part 9a is formed on the portion of the projecting part 9. Furthermore, the wall thickness of the projecting part 9 is preferably made to be uniform in order to prevent a sink mark from developing due to the thermal lowering after the injection molding of the valve.

IPC: G01N22/04
Filed: 1994-09-16
Abstract: PURPOSE: To enable a specified result of cooking to be always attained without having any relation whether or not a wrap is applied over a food to be cooked by a method wherein a heating and cooking operation is controlled in response to whether or not the wrap is applied to the food to be cooked. CONSTITUTION: A control circuit calculates a reference discrimination time for discriminating whether or not a wrap 12 is applied over a food 1 in reference to a weight of the food 1 read from a weight sensor 18 in advance and compares it with a counted value of a timer 2. In the case that the counted value of the timer 2 is shorter than the reference discriminating time as a result of comparison, the control circuit judges that the food 1 being heated and cooked at present is not provided with the wrap 12 and determines a cooking time.  In the case that the counted value of the timer 2 is longer than the reference discriminating time, the control circuit judges that the food 1 being heated at present is applied with the wrap 12 so as to determine the cooking time, With such an arrangement as above, it is possible to get a positive result of cooking which is always kept constant without having any relation with whether the wrap 12 is applied or not.
