Abstract: When the operation of any of manufacturing apparatus is halted, influence exerted by the operation halt on the manufacturing state of each of products is evaluated based on the difference between the number of products in a processing waiting state in the manufacturing apparatus at a time at which the operation of the manufacturing apparatus is halted or at a time antecedent thereto and the number of products in the processing waiting state in the manufacturing apparatus at a time at which the manufacturing apparatus is reoperated after the operation thereof is halted or at a time posterior thereto or on the difference between the period during which the product processed by the manufacturing apparatus during a given period antecedent to the time at which the operation of the manufacturing apparatus is halted is in the processing waiting state in the manufacturing apparatus and the period during which the product processed by the manufacturing apparatus during the given period posterior to the time at which t

Abstract: A processing result storage device stores data on the results of an etching apparatus having processed a product. An apparatus property storage device stores data which indicate the property of the etching apparatus as processing property data. A process stability judgment device judges the stability of a step based on the processing result data stored in the processing result storage device and the apparatus property data stored in the apparatus property storage device. When the process stability judgment device has judged the step to be stable, the processing rate automatic calculation device calculates an etching rate. On the other hand, when the process stability judgment device has judged the step to be unstable, the processing rate recalculation device calculates an etching rate, based on the results of the etching apparatus having actually etched. The processing requirement determination device determines the etching requirements from the calculated etching rate.

Abstract: A variable F (a, n) defined by Equation (1) (wherein k (a, n) is a constant set on a step P (a, n) which is the nth step of a product a, Tave (a, n) is an average wait time for the same step as the step P (a, n) which is obtained from the past processing results, Tw1 (a, n) is a processing wait time which is a time difference between a processing end time for a step P (a, n--1) and a processing start time for the step P (a, n), N (a) is a final step for the product a, Te (a, N(a)) is a end time for a final step P (a, N(a)), Tout (a) is a target delivery date for The product a, and E (a) is the number of steps in which the product a is not yet processed) is set on all manufacturing steps of a product which is put in a manufacturing line. The processing start and end times for each step are determined in such a manner that the absolute value of the variable F (a, n) is smaller than a preset constant Fmax which is equal to or greater than 0 so that an initial manufacturing project is formed.

Abstract: The directivity as well as the gain of an antenna element associated with a finite length reflector, which includes a feed antenna such as a dipole antenna and a reflector having a finite length of several wavelengths or less, are improved by disposing a non-feed loop element having a peripheral length of about 2 wavelengths along a common imaginary plane with the feed antenna so as to surround the feed antenna. Preferably, the non-feed loop element is disposed in parallel to the reflector, and more preferably it is disposed nearly symmetrically with respect to the center of the feed antenna.

Abstract: An operating mode switching mechanism for a tape recorder for effecting various operations in response to operation of manually operating keys comprises a single solenoid for causing a rotary wheel to start rotating so that various operations are selectively performed depending on the duration for which the solenoid is energized by moving a carrier plate carrying thereon an electromagnetic transducer head, between first and second positions. The rotational angle of the rotary wheel is detected by a photo sensing means, and the detected angle will be used in an electrical circuit in which three different pulses for energizing the solenoid are selectively produced in accordance with the selected operating key and the detected rotational angle of the rotary wheel. Energization interval of the solenoid is, thus synchronized with the rotation of the solenoid thereby providing accurate operating mode switching operations.
