Patent JP-S60257541-A (JP)
Title: Production of semiconductor device
Inventor: SAKURAI HIROMI
IPC: H01L21/76
Filed: 1984-06-04
Abstract: PURPOSE:To prevent an SiO2 film from being etched during epitaxial growth as well as to reduce defects in the periphery having vertical walls and surrounded by the isolating oxide film and by providing a thin insulating film containing no oxygen on the surface of the inner wall of the aperture and the upper face of the SiO2 film, and then forming an active region by causing Si to grow epitaxially. CONSTITUTION:An SiO2 film 2 is formed on an Si substrate 1 and provided with an aperture 3 by anisotropic etching such that the aperture has vertical walls. The upper face of the SiO2 film 2 and the internal wall faces of the aperture are covered with an insulating film containing no oxygen, e.g. with an Si3N4 film 5, such that a second aperture 6 is provided within the aperture 3 while a part of the Si substrate 1 is exposed on the bottom of the aperture. An Si layer 4 is then selectively caused to grow epitaxially within the second aperture 6. Subsequently, protruded portions of the epitaxially grown Si layer 4 and the Si3N4 film 5 on the upper face of the SiO2 are removed by polishing so as to flatten the surface and to obtain an active region 4a. In this manner, the aperture walls are not etched any way during the epitaxial growth, and therefore the verticality of the walls can be maintained.

IPC: C23C14/58
Filed: 1987-05-14
Abstract: PURPOSE:To carry out anticorrosive treatment and coloring of a steel material with a long service life by galvanizing the iron-based material, plating it with copper and chemically treating the resulting copper layer. CONSTITUTION:A steel sheet 1 is galvanized to form a zinc layer 2 and this layer 2 is plated with copper which is liable to form a colored film by a chemical reaction by conventional electroplating or other method to form a copper layer 5. A light-brown or brown colored chromate layer 6 is then formed on the layer 5 by chromating the layer 5. The color tone of the colored chromate layer 6 depends on the compsn. of a chromating bath, immersion time and chromating temp. and the layer 6 can be colored green. A copper-zinc alloy layer contg. 0.01-10wt.% copper may be formed on the steel sheet 1 and colored by chemical treatment.

Title: Ink-jet type recording apparatus
Inventor: USUI HISAKI
IPC: B41J2/045
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To maintain an ink amount constant correspondingly to a change of an external environment, by arranging a means for outputting to a piezoelectric vibrator a driving signal executing a second swell process whereby a pressure generation chamber is swollen to show a smaller volume change than at a first swell process, a shrink process whereby the pressure generation chamber is shrunk, etc. SOLUTION: A control means outputs first discharge pulse in response to a printing signal output from a host, thereby discharging charges of a piezoelectric vibrator 5. In consequence, a pressure generation camber 2 is swollen by an amount corresponding to a potential difference of a first hold voltage and a zero potential and a meniscus of a nozzle opening 13 is greatly drawn to the pressure generation chamber 2. The control means outputs a first charge pulse before and after the vibration of the meniscus reverses, thereby quickly charging the piezoelectric vibrator 5, whereby the pressure generation camber 2 is shrunk suddenly by an amount corresponding to a potential difference of a second hold voltage and the zero potential. As a result, the ink in the pressure generation chamber 2 is pressured and the meniscus is pressed from the present position to the nozzle opening 13.  The ink is discharged as ink drops from the nozzle opening 13.

Title: Manufacture of resin filled with filter
Inventor: TAMAOKI AKINOBU
IPC: C08J3/20
Filed: 1986-05-21
Abstract: PURPOSE:To make a filler hard to settle even under long-term storage, by a method wherein a liquid resin compound which has been expanded thermally through heating is filled with the filler obtained by mixing up two kinds of the fillers whose particle diameter ratios are specific with each other so that a filling ratio at a room temperature becomes a specific one and the liquid resin composite filled with the filler is cooled. CONSTITUTION:Manufacture of resin filled with a filler includes mixing up two kinds of the fillers whose particle diameter ratios are 5 or more with each other at the ratio between 50wt% or more of the filler whose particle diameter is large and less than 50wt% of the filler whose particle diameter is small. A liquid resin compound which has been expanded thermally through heating at the temperature of 50 deg.C or more is filled with same filler so that a filling ratio at a room temperature becomes 40vol%-80vol%. The liquid resin filled with the filler is cooled. As a filler content becomes high because sizes of the fillers are different from each other and the filler is cooled after the filling, the filler becomes hard to settle.

Abstract: PURPOSE:To keep the mold temperature approximately constant at desired value even when ambient temperature changes and consequently manufacture the product having stable quality by a method wherein set temperature is corrected in response to the output of a second temperature measuring means for measuring the measuring the ambient temperature. CONSTITUTION:The temperature theta2 at a heating part measured by a thermocouple 1a is transferred through an A/D converter 6 to a CPU 7d, resulting in outputting command signal from the CPU 7d so as to bring the temperature theta2 at the heating part close to a set value theta0'. Said command signal is transferred through an input-output port 7c in the form of on-off signal to a photo- coupler 9a so as to control the electric current, which flows through a heater 10a. Thus, the set value theta0', which is the desired value of the heating part, is obtained from the set value theta0 of the mold temperature of each injection molder and ambient temperature theta1 so as to control each temperature in order to keep the temperature theta2 at the heating part at the set value theta0'. Thus, the mold temperature can be kept constantly regardless of the change of the ambient temperature.
