Title: Relative position detecting device for mask substrate and wafer
Inventor: SHINOZAKI TOSHIAKI
IPC: H01L21/67
Filed: 1981-04-17
Abstract: PURPOSE:To detect the shifted location with high precision by a method wherein the alignment reference points on the mask and the wafer are illuminated by the single color light with the specified wave length to form the image of each location data on the same plane by means of diffracting the Fresnel zone plate. CONSTITUTION:The single color light with the wave length of lambda is illuminated through the intermediary of the prism 6 to provide the Fresnel zone plate with the focus f1 at the first degree of diffraction on the image forming location focussing on the alignment reference point 4 on the wafer 3. In case the gap between the mask 1 and the wafer 3 is d, if the expression fXlambda=n(f1-d)Xlambda with the n degrees selected is satisfied, the Fresnel zone plate 7 can also focus the alignment point 2 of the mask 1. Thus the alignment reference points 4, 2 of the wafer 3 and the mask 1 may become parallel with each other at the first and the n-th diffraction of the Fresnel zone plate and the image are formed on the light receiving surface of the photoelectric detector 9 by means of the relay lens 8 detecting the relative locations easily with high precision.

IPC: H04N9/75
Filed: 1981-04-17
Abstract: PURPOSE:To eliminate a color phase component in reference phase with a video signal of the NTSC system by finding a phase difference between a color signal being separated digitally in color, and the reference phase in the form of a function value, and obtaining a chromakey signal. CONSTITUTION:Sampling phase timing is set on axes I and Q and a ditized NTSC video signal fND is supplied to an YC separating circuit 21 to find an I and a Q value, which are applied to an IQ separating circuit 22. An I and a Q signal separated by the IQ separating circuit 22 are applied to a phase detecting circuit 23 and a chromaticity detecting circuit 24. The phase detecting circuit 23 detects a phase theta from the I and Q signals and generates a function in such a way that as a difference between the phase theta and a reference phase phi is  greater and greater, sensitivity is lower and lower. A multiplier 25 multiplies  this key signal by a chromaticity signal to generate a color cancellation signal eliminating a color component in reference phase phi.

IPC: H04N7/01
Filed: 1990-03-08
Abstract: PURPOSE:To reduce a chip area in the case of circuit integration and to decrease power consumption by giving only an output of one latch circuit to a 1H delay means. CONSTITUTION:When an input video data is an odd number line, a selector SL8 selects a data F, an SL16B selects an output of a latch 12B and a select signal corresponding to an even number line is inputted to the SL16A to select an output of a latch 12A. Thus, a 1H delay data E is delayed further by a 1/2 data and outputted from a video delay circuit 18, and a data resulting from delaying the data E by 2H is outputted from a video delay circuit 19. Moreover, when an input data is an even number line, the SL8 selects the data E, the SL16B selects an output of the latch 14B and the SL16A selects an output of the latch 14A respectively. Thus, the data E which is delayed by 1H is delayed further by 1/2 data and outputted from the circuit 18, and a 2H delay data is outputted from the circuit 19. Then an adder 21 adds an output of an adder 20 and a video data in 1H preceding and outputs the result.

Abstract: PURPOSE:To provide a measuring apparatus, which completes combination of items to be measured quickly, by setting the optimum input condition in conformity with the actual state of the distribution of weights of items to be measured. CONSTITUTION:When a weight value W of an item to be measured is not in the proper range, the operation of a measuring apparatus is stopped, or it is judged that the item to be measured is axcessively large or excessively small, and the item is classified (S310-S360). When the weight value W is adequate, an average weight AW and a standard deviation S are computed again (S370). As a result, an intermediate weight tolerances WU [n] and WL [n] vary. The weight value W of the item to be measured is added to the intermediate value before the input for each hopper. When the added value A is within the intermediate weight tolerance, the item to be measured is inputted into the optimum hopper. When the value is not within the tolerace, the item to be measured is processed as the item to be returned. (S380-S440). Since the intermediate weight tolerances WU [n] and WL [n] are corrected based on the actual average weight AW and the standard deviations, the optimum input condition can be set.

Abstract: PURPOSE:To secure easily the phase balance between the tweeter and the woofer, by distributing the non-vibrating parts of two woofers in a body and back to back with one of the two woofers set into the same direction as the tweeter. CONSTITUTION:Both woofer 210 and middle tweeter 220 are attached to buffle plate 230; and another woofer 211 is fixed to the opposite buffle plate 231. Speakers 210 and 211 are set back to back with their non-vibrating parts 210a and 211a unified into a body mechanically. In case some distance exists between speakers 210 and 211, these two speakers are connected via coupling means 270. In such constitution, both speakers are driven with the common power source. Thus the forward movement of one speaker's diaphragm will give the advance also to the diaphragm of the other speaker. So is for the backward movement of these diaphragms. Thus the same breathing vibration as the natural musical instrument is imitated substantially. And the phase matching is easy between the tweeter and the woofer since speaker 210 is turned to the same direction as speaker 220.
