Title: Shaping method using heat fusing powder
Inventor: NAGAMORI SHIGERU
IPC: B23K26/34
Filed: 1988-03-14
Abstract: PURPOSE:To shape a specified shape material with an inexpensive material by moving beams toward a flat layer of powder to irradiate it, forming a section shaped molten curved material, feeding the powder continuously, directing the beams and forming the molten cured material. CONSTITUTION:Heat fusing powder 18 is fed from a quantitative feeder 20 onto a table 12 to form flat layer. Then, beams 32 are directed toward the upper surface of a flat layer of the powder 18 by actuating a laser transmitter 30 and also the beams 32 are moved after the section shape of an object shaped material by actuating a laser scanning device 26 and varying continuously the angle of a mirror 24. The powder 18 irradiated with the beams 32 is immediately melted and cured to form a molten cured material 34. Further, a table 12 is lowered by required height, and the powder 18 is fed onto a powder flat layer, while the beams 32 are directed and moved. The object shaped material is formed as a laminated molten cured material 34 by repeating said procedures. The object shaped material shaped thus can be shaped with an inexpensive material such as metallic powder or the like.

Abstract: PURPOSE:To ensure a frequency characteristics for a converting circuit itself, by forming a feedback line with a series or parallel circuit of CR at the positive and negative inputs of a differential operational amplifier and using the double terminal impedance which is between the positive input and a common potential point. CONSTITUTION:A differential operational amplifier A has a sufficiently large gain, and the output of the amplifier A is fed back to a negative and positive inputs via a parallel circuit of a capacitor C1 and a resistor R1 plus a series circuit of a capacitor C2 and a resistor R2 respectively. Then a proper resistance R is connected between terminals 1 and 1' to obtain the negative L, C and R impedance circuits equivalently at terminals 2 and 2'. Accordingly the out-of-band characteristics becomes stable at a high frequency since the terminals 2 and 2' approximate gradually to an open state.

IPC: H01L21/027
Filed: 1986-03-19
Abstract: PURPOSE:To enable occurrence of pinholes in spin coating to be prevented and a Cr film to be etched using a thin film resist by once forming a thick resist film by the spin coating process, and then, uniformly etching the whole surface of the thick resist film after baking it. CONSTITUTION:The 500-1,000nm thick resist film 5 is formed on the Cr film 3 (light shading film) formed on the surface of a glass substrate 1 under usual easy conditions by using a usual spin coater and feeding a resist solution through a resist feeder 7. For example, when a novolak type resist is used, the glass substrate 1 is etched on the whole surface by immersing it into a dissolving solution of KOH or the like, or the spin-and-spray process to form the thick resist film into the thin film resist 50 having a desired thickness of 100-300nm. At the time, this film thickness can be controlled by irradiating, for example, laser beams, and executing low speed etching while monitoring reflection interference. This thin film resist 50 is exposed and developed, and the Cr film 3 is etched by using this resist as a mask, thus permitting the thin film resist 50 freed of pinholes to be formed.
