Title: Inverted pattern forming apparatus
Inventor: ARAI TETSUYUKI
IPC: H01L21/66
Filed: 1987-02-06
Abstract: PURPOSE:To form a synthesized inverted pattern readily, when image data are prepared according to design pattern data, by adding positive or negative flags and region setting data. CONSTITUTION:Design pattern data DA-DC for design patterns A-C are read through a magnetic tape reader 23 and put into a minicomputer 24. The data are converted into formats for divided regions (X1, Y1)-(X3, Y3). Flags for inverted images or positive images are added to the design pattern data of the inverted pattern or the non-inverted patterns. The design data for pattern forming regions are also added. The data are stored in a magnetic disk 25. The design pattern data of the divided region, which is one step further than the applicable divided region, are inputted into a raster conversion circuit 26 from the disk 25. A bit pattern is formed. Which of the positive image or the inverted image is used for drawing is determined based on flag information, and the result is inputted into a bit pattern memory 27. The output of the memory is compared with the data of a mask 32 in a circuit 31 for defect, comparison and judgement.

Abstract: PURPOSE: To easily produce a mold provided with gagging lugs of high weld strength by providing cast holes of a polygonal shape to the side walls of a mold for casting steel ingot, fixing gagging lug members therein by means of wedges and welding these.  
     CONSTITUTION: A mold for casting formed with cast holes for mounting gagging lugs on the side walls is cast. The rod 22 of a gagging lug 21 for mold having been manufactured separately is fitted into each of the cast holes of this mold from the outer side of the mold, and is fixed to the inside surface of the cast hole by means of a wedge 31. Next, the rod part 22 of the member 21, the wedge 31 and the inside surface of the cast holes of the mold are arcwelded by using a steel-base welding rod. These are welded until deposited metal goes flush to the inside surface of the mold, and the part projecting from this plane to the outside is ground off. In using the mold, the peeling of the deposited metal of the gagging lugs or the failure of the gagging lugs themselves or the mold body does not occur. The mold for casting firmly weld-fitted with the gagging lugs is easily produced.

Title: Two-wavelength absorption photometer
Inventor: SUZUKI RIYOUICHI
IPC: G01J3/427
Filed: 1978-03-10
Abstract: PURPOSE:To improve the accuracy of a two-wavelength absorption photometer by dividing light passing through a specimen and alternatively exchanging two filters of different optical paths to simultaneously produce photo current from the respective detectors. CONSTITUTION:The light passed from a light source 13 passes a specimen 15 and is divided via a beam splitter 16 and reflecting mirror 17 into two first and second optical paths. The lights are simultaneously passed through monochromatic filters Flambda1 18 and Flambda2 19 for passing light of wavelength lambda1 attached to one rotary member into detectors 21, 22. That is, the light of lambda1 is inserted into first optical path at first duration and light of lambda2 is inserted into second optical path at the same first duration, and vice versa at second duration as rotated by half. Thus, upon rotation of a rotary shaft 20 the first and second durations are continuously alternatively generated. Accordingly, both the detectors 21, 22 share equally the information of lambda1, lambda2 of wavelength so as to cancel the difference of the detectors 21, 22 and also the unbalance due to the division of the light in order to enhance the accuracy of the two-wavelength absorption photometer.

Abstract: PURPOSE:To make a portable radio equipment miniature and light in weight by switching the value of a direct current voltage generated by a reference voltage generation circuit, which is controlled by the output of a voltage detection circuit and defines the logical output of a logical circuit and the output of the logical circuit as inputs, and sending a signal corresponding to a ground signal as well with being loaded on a high frequency feeding line. CONSTITUTION:A current passing element 43 is connected between the direct current circuit and ground of a booster amplifier 1 and a voltage detection circuit 43 is inserted to the direct current circuit of a portable ratio equipment 3. When the booster amplifier 1 is connected to the portable radio equipment 3, a current flows from a reference voltage generation circuit (VREF) 35 through the voltage detection circuit 43 to the current passing element 23 and this current is detected by the voltage detection circuit 43. Then, the output of the circuit 43 controls a LOGIC 34 and a VREF 35. Accordingly, the LOGIC 34 and VREF 35 are operated samely as a case that they are controlled by the ground signal. Thus, since a ground signal terminal can be further omitted from the portable radio equipment, the portable radio equipment can be miniaturized further easily.

Abstract: PROBLEM TO BE SOLVED: To reduce the circuit scale of a device itself with the same constitution even in the case where devices of the same constitution are prepared according to a division number at the time of dividing multibit data into plural parts to perform ECC control. SOLUTION: Multibit data 101 are divided into plural blocks, and check bit generation circuit 10A and 10B are provided correspondingly to each block. Check bit intermediate data generation parts 240A and 240B use party check matrixes, which have symmetry in associate matrix expression, to generate check bit intermediate data of each block. At this time, a block obtained by changing the byte order of an input block in consideration of symmetry of check matrixes is selected by a selector 235B to generate intermediate data with respect to a lower-order block. These intermediate data are transmitted and received through a signal line 250 to generate entire check bits in check bit generation circuits 255A and 255B. With respect to check bits related to the lower-order block, bytes are transposed by a selector 260B to output block data 107 and 108 and their check bits 109.
