Title: Cement-type inorganic board with joint pattern and its production
Inventor: FUJII KEIKO
IPC: B28B11/10
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To provide a cement-type inorganic board with a joint pattern which can prevent the generation of bursting in through holes. SOLUTION: In a cement-type inorganic board with a joint pattern manufactured by a process in which one side of an unhardened cement-type inorganic board 2 in which through holes 1 opening on a side end surface are formed in the thickness is pressed to form an uneven joint pattern, and the board 2 is dried and hardened, the through hole is formed to have a cross section of a rounded quadrangle. Since the stress concentration at the rounded corners of the through holes 1 is prevented, even when the steam pressure in the through holes 1 is increased by the evaporation of water during heat-drying the unhardened board 2, the generation of bursting can be prevented.

Title: Sound drop-out compensating method
Inventor: YUASA MASATOSHI
IPC: G11B20/06
Filed: 1986-09-10
Abstract: PURPOSE:To prevent the generating of a noise by connecting a sound signal before and after a drop-out. CONSTITUTION:A drop-out detecting circuit 32 detects a drop-out and generates a detecting signal. During the period, an address counter 26 stops an action changed to the value of an address memory 36. After the detecting signal is completed, when the detecting signal is inputted, the counter 26 increases successively the value of the address again and re-starts the writing of a compressed sound signal to a memory 20. The writing signal is read in accordance with the compressibility from a control code identifying circuit 28, converted to an analog signal by a D/A converting circuit 22, and then, a continuous sound signal is obtained and the prevention of the generation of the noise can be executed.

Title: Manufacture of liquid crystal display panel
Inventor: ASADA JUNICHI
IPC: G02F1/13
Filed: 1987-08-27
Abstract: PURPOSE:To eliminate the unbalance of the tension of a bag, and to prevent the generation of the dislocation of the upper and lower substrates, by holding a cell in a position where the interval of the inner peripheral edge of an annular plate material having the thickness of 1.5-3 times of the thickness of the cell and having a groove part on a surface, and the outer peripheral edge of the smaller substrate of the cell becomes symmetrical against the center of the smaller substrate. CONSTITUTION:Large and small substrates 1, 2 with an electrode are opposed through a thermosetting sealing material 13 and a spacer material 14 and aligned exactly, thereafter, stuck to each other, and formed so that the center of the smaller substrate 2 becomes eccentric relatively in the left direction of the paper surface against the center of the larger substrate. The stuck cell 3 is inserted into a bag-like heat resisting film 16, in a state that it has been held in a planar jig. It is brought to pressure reduction by using a vacuum packing machine, thereafter, the film 16 is sealed by a heat seal 17, and the periphery is returned to the atmospheric pressure. Accordingly, the cell 3 is pressurized by the atmospheric pressure through the film 16. In such a way, since the cell 3 is positioned so as to become symmetrical against the center of the substrate 2, the tension of a bag becomes equal at both sides, and the dislocation of the upper and lower substrates is not generated.

Title: Metal with high free-cutting property
Inventor: YOSHINAKA MINORU
IPC: C22C49/00
Filed: 1988-08-29
Abstract: PURPOSE:To reconcile high free-cutting property and improvement of mechanical strength with each other by blending zinc-oxide whisker with metal and also specifying the diameter of the base part of the whisker and the length of the whisker from the base part to the tip, respectively. CONSTITUTION:Zinc-oxide whisker is blended by about 0.1-50vol.% with a metallic raw material, such as Al, Mg, Cu, Ti, and alloys thereof. As the above whisker, the one in which the diameter of a base part and the length from the base part to the tip are regulated to 0.7-14mum and 3-20mum, respectively, is used. Further, it is preferable that the whisker is composed of a nucleus part and the part of acicular crystals spreading from the nucleus part in dissimilar plural axial directions. Since the zinc-oxide whisker is a pure single crystal and has a cleavage plane in a direction perpendicular to the C-axial direction, high free-cutting property can be provided only by blending this whisker by small amounts with the metal. Moreover, by using a tetrapod-like article as raw material, the whisker contributes toward uniform dispersion into matrix and effectively serves to improve free-cutting property and mechanical strength.

CONSTITUTION:In a bend point detecting part, the outline of a character pattern read  out from a character pattern memory 31 is traced by an outline tracing part 32, and  coordinates of outline points are stored in a memory 33. In a line parameter calculating part 34, parameters (a)-(c) of the expression of a line connecting start point coordinates 35 and K-th outline point coordinates 36 are calculated. I-th outline point coordinates 37 are read out from the memory 33, and the length between these coordinates  and the line is calculated by a length calculating part 38. A maximum value of (K-1)- number of calculated lengths is obtained in a maximum value selecting part 39. This  maximum value is compared with a threshold value in a discriminating part 40; and if  it is smaller than the threshold value, an indication is given to the memory 33 to repeat  the operation for the next (K+1)th point. If the maximum value is larger than the  threshold value, the outline point giving this maximum value is defined as a bend point.
