Abstract: PROBLEM TO BE SOLVED: To readily produce a high-silica zeolite having specific X-ray diffraction peaks and a porous structure by mixing an oxide selected from Si and Ge with a selected metal oxide in a specified molar ratio, adding water and an organic compound thereto, carrying out a thermal reaction and then removing the organic compound. SOLUTION: A first component of an organic compound comprising a di- quaternary salt of 1,1'-butylenedi(4-aza-1-azonia-2,5-dimethylbicyclo[2.2.2]octane), water and an oxide of an element selected from Si and Ge or its mixture is mixed with a second component of an oxide of an element selected from Al, B, Ga, Fe, Ti and Zn or its mixture.

Title: Pseudo half-tonal image transmission method for facsimile equipment
Inventor: OKUBO YUKO
IPC: H04N1/41
Filed: 1987-01-23
Abstract: PURPOSE:To reduce the quantity of codes to be transmitted by generating plural picture element patterns the numbers of black picture elements included in whose unit blocks are different from each other, substituting the unit picture element block in a transmission original with one of said picture element patterns, and directly coding this picture element pattern to transmit. CONSTITUTION:At the time of transmitting a facsimile message, a square area of 4X4 pieces of picture elements is taken out and the area is made a unit picture element block on the transmission side, the tone of this square area is determined from the densities of each one of the sixteen picture elements, thus generated tone is coded then transmitted. On picture element necessarily comes to be either a white or a black picture element, hence, there are two information present for one picture element. Therefore, since one picture has one bit of information, sixteen bits of information is included in said 4X4- picture-element unit block. In case the dither system is used, sixteen gradations can be expressed by means of picture element pattern. Therefore sixteen codes are necessary, and 4 bits are enough for the coding. By thus coding the gradations directly, the quantity of transmission codes can be reduced.

Abstract: PURPOSE: To bring out medium tone wherein the turbidity and displacement of colors are inconspicuous by using the color mixture by juxtaposition and that by a color reduction method properly and separately in accordance with the density of color in a colored-image recording method wherein ink of multiple colors is jetted in dot matrixes numbering n×m.  
     CONSTITUTION: In the case when a colored image represented by medium tone is formed by using image elements consisting, for instance, of dots numbering 3×3, a dot-matrix table wherein a cyan color takes a dot pattern formed by extending a recording area from an upper-left corner as a starting point toward a lower-right corner with the rise in a density level and wherein a magenta color and a yellow color take dot patterns formed by extending the recording area from a lower-right corner and from a lower-left corner respectively is employed as the one for each color employed for the aforesaid image elements. Accordingly, in a middle-low density area, colors overalp little with each other to present the color mixture by juxtaposition, which is superior in brightness, and in a high density area, the colors overlap with each other to present the color-mixture by the color-reduction method, whereby the conspicuousness of the displacement of color is prevented.

Abstract: PURPOSE:To prevent the formation of any irregular shaped part at the end part and improve the yield of width adjustment by screwing down by the amount of predetermined calculation at the time of adjusting to decrease the width of the end parts in the lengthwise direction of a slab by a predetermined amount. CONSTITUTION:The end part 2 of a slab 1 of width H0, thickness W0, and length L0 is screwed down by a forging to 6.

Title: Alternating current power source system
Inventor: ISHIDA ISATO
IPC: H02J9/06
Filed: 1990-01-26
Abstract: PURPOSE:To switch to a plurality of AC power source at arbitrary timings by controlling the voltage of at least one AC power source, in order to cause a current to flow in the reverse direction to a load current flowing in a bidirectional semiconductor switch, in accordance with a result judged by a discriminating means and a detecting means. CONSTITUTION:When t<t1, V1 (the voltage of an AC power source 1) < V2 (the voltage of an inverter 2) is discriminated by detecting that a semiconductor element is on. And, the inverter 2 controls the voltage so that V1>V2 may be satisfied at time t=t1. The output of a voltage discriminating circuit 6 changes at time t=t2 when V1>V2 was satisfied. This signal change gives an ON signal to a bidirectional semiconductor switch 4. When the switch 4 was turned on, voltage of V1-V2 is applied to the semiconductor switch 32 in order to cause a current to flow in the reverse direction to a load current. When the current became zero, the load current begins to flow through the switch 4 from the inverter 2.
