Inventor: HIROSE YOSHIOKI
IPC: B22C1/18
Filed: 1984-08-22
Abstract: PURPOSE:To form a casting mold having a dense surface by forming a mold coating material consisting essentially of a binder, refractory material and hardener into a two-liquid type, incorporating the binder contg. an acidic silicic acid sol into the 1st liquid and incorporating the alkaline hardener into the 2nd liquid. CONSTITUTION:The mold coating material 4 prepd. by mixing the 1st liquid and 2nd liquid with the refractory material is sprayed onto the surface of a pattern 3. Molding sand 6 added and mixed with the binder is then packed into a molding flask 5 before the mold coating material layer 4a cures. CO2 is then passed into the flask 5 to cure the sand 6. The layer 4a cures by reacting with the sand 6 from the point of the time when said layer is embedded into the sand 6 and therefore the boundary faces between the sand 6 and the layer 4a are adhered and solidified. The casting mold 7 transferred with the layer 4a to the sand mold is thus obtd. when the pattern 3 is removed.

Title: Method for detecting alignment mark in electron beam lithography system
Inventor: MATSUOKA GENYA
IPC: G06T7/00
Filed: 1993-07-15
Abstract: PURPOSE:To realize highly accurate lithography by evaluating a detected waveform and removing defective signals thereby preventing erroneous detection of alignment mark using correlation processing. CONSTITUTION:A detection signal 411 is subjected to smoothing thus removing noise therefrom. It is then subjected to first degree differentiation and the polarity at the negative part of differentiated signal is inverted to produce a waveform 101. The interval between peaks of the waveform 101 depends on the width of used mark and the degree of blur at the edge of electron beam. The P-P value of the signal provides a guide in the decision whether a correct groove is present in the detection signal. When these values are determined, a decision can be made whether the detection signal is a correct signal or not.

Filed: 1992-07-02
Abstract: PURPOSE:To prevent generation of through current by providing voltage level converting means and pulse generating means for supplying different pulses to control terminals of a switching element from a reference signal and a control signal. CONSTITUTION:A control circuit 60 for executing a pulse width modulation of a pulse generator 21 has differential amplifiers in pulse generators 21.

Abstract: PROBLEM TO BE SOLVED: To recover the construction wastes produced from a building site with high efficiency by collecting and carrying the construction wastes with a collection bag provided with an index for separation, and consistently processing the wastes on the basis of the index for separation to a final disposal place. SOLUTION: It is required that the wastes are completely separated on the basis of indexes consistently to the final disposal place through the collection and conveying of the construction waste, to recover and recycle at high efficiency the construction wastes produced in a building site. As the most desirable index, the color indexes for separation are used.

For example, the bag made of a polypropylene film reinforced by woven net is used. Only by packing the wastes by separating the same in the bags of different colors, the various kinds of wastes can be prevented from being mixed by mistake, and the forwarding after the use of bags becomes unnecessary.
