Filed: 1988-07-06
Abstract: PURPOSE:To obtain the title high-purity artificial quartz crystal having a low content of impurities, especially of Al, and having excellent radioactivity resistance by using specified crystalline silica as the raw material at the time of producing an artificial quartz crystal by hydrothermal growth. CONSTITUTION:When an artificial quartz crystal is produced by hydrothermal growth, amorphous silica contg. <=10ppm of the impurities of the alkali (alkaline earth) metal elements such as Li, Na, K, Mg, and Ca and transition metal elements such as Al, Ti, Cr, Fe, and Cu is impregnated with an aq. soln. (e.g., an aq. NaOH soln.) contg. alkaline compds. selected from Na, K, and Li to increase the crystallization rate and to lower the treating temp. The impregnated silica is then dried to control the content of alkali metal elements to >=5ppm, and then heat-treated preferably at 900-1,600 deg.C to convert the silica to crystalline silica contg. cristobalite. The crystalline silica is used as the raw material.

IPC: G06T5/00
Filed: 1989-06-30
Abstract: PURPOSE:To eliminate dots in a low-density part, a link of void in a high-density part, and a chain texture in middle and low-density parts by providing an already binarized window in the periphery of a weighted picture element, and changing and correcting the arrangement of a dot pattern in the window based on this dot pattern. CONSTITUTION:A binarized signal correcting circuit 7 provides a 3X3 window for an already binarized signal and identifies whether it is adapted to the pattern. That is, an already generated texture is recognized to check whether it is necessary that the arrangement of the binarized signal is broken to correct the regular texture or not. If it is recognized that the texture to be corrected is generated, a correction pattern is selected and the binarized signal in the window is corrected in accordance with this correction pattern. Thus, dots and a link of void in the error diffusion method and an uncomfortable texture in middle and low-density parts are eliminated.

Title: Aqueous bakable coating composition
Inventor: TADENUMA HIROSHI
IPC: C09D7/12
Filed: 1989-06-30
Abstract: PURPOSE:To prepare an aq. bakable coating compsn. which service for wt. reduction and gives a coating film excellent in the appearance by compounding a carboxylated acrylic polymer with specific hollow particles of a carboxylated polymer. CONSTITUTION:100 pts.wt. carboxylated acrylic polymer is compounded with 1-200 pts.wt. hollow particles of a carboxylated polymer having a toluene- insoluble content of 50wt.% or higher and a glass transition temp. of at least 60 deg.C give an aq. coating compsn. A pref. outside diameter of the hollow particle is 0.05-50mum; the outside diameter smaller than 0.05mum tends to cause crack in the coating film, while that larger than 50mum gives the coating film a poor flatness and an inferior gloss and makes the coating film easily stainable with time. To obtain a good balance between wt. reduction and appearance, a pref. inside diameter is 0.2-0.8 time as large as the outside diameter; the inside diameter smaller than 0.2 time gives a coating film inferior in the opacity and wt. reduction, while that higher than 0.8 time gives a coating film with an inferior hardness.

Abstract: PROBLEM TO BE SOLVED: To provide a vacuum cleaner wherein a motor-operated blower can be controlled according a cleaning operation without complicating construction so that malfunctions can be avoided. SOLUTION: A grip pat with an operation means 34 to set a drive condition of a motor-operated blower M is provided at one end of a hose, the other end of which is connected to a body of vacuum cleaner. A cleaning condition detecting sensor 45, wherein a conductive rolling body is disposed between a pair of spaced apart electrodes so as to roll, is provided at a grip part which tends to vibrate due to cleaning and in which a signal line 50 of the operation means 34 can be utilized. The means 34 is set to drive the blower M, thereby performing cleaning.

Title: Chrominance signal processor

IPC: H04N9/88
Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To prevent the hue disturbance by evading the missing of the input signal of a 2nd frequency divider even though a horizontal synchronizing signal is missed by the drop-out, etc. SOLUTION: A 2nd VCO 20 has its central frequency of almost double fH (horizontal scanning frequency) and has its output signal frequency which is halved by a 1st frequency divider 21. A 2nd phase comparator 18 compares the phases with each other between the output signal of a horizontal pulse circuit 17 and that of the divider 21. A 2nd output phase error signal is smoothed by a 2nd LPF 19 and controlled, so that the oscillation frequency of the VCO 20 has double fH. Therefore, the output signal of the divider 21 is equal to fH. In such a constitution, the oscillation of the VCO 20 is carried on despite the missing of a horizontal synchronizing signal. As a result, the output signal of the divider 21 is never missed. Thus a 1st switch circuit 15 never has the hue disturbance of a 3H period with no inversion caused in the selecting procedure of signals (a) and (b).
