Abstract: PURPOSE:To easily detect an error by means of visual observation when the segmenting result of a unit character string is incorrect by displaying the original image of a binarized image of a unit character string and a frame-type graphic form formed by the circumscribed frame rectangle of the unit character string. CONSTITUTION:Frame type graphic forms 6a-6c formed by the coordinates of the circumscribed rectangle of a unit character string based upon a segmented result are displayed on a display screen so as to surround the binarized image of the unit character string entered as a character string indicating the function of a symbol graphic form. When the distance between each two characters existing in a unit character string 1c (CNT) indicating the function of a symbol graphic and a unit character string 1d (M74HC163) indicating a symbol name is less than a previously determined distance, both the unit character strings 1c, 1d are extracted as one unit character string (CNTM74HC163). When the frame type graphic forms 6a-6c formed by the coordinates of the circumscribed rectangle of the unit character string based upon the segmented result are superposed on the extracted unit character string and displayed, the error of the unit character string segmented result can be easily detected.

Title: Manufacture of semiconductor substrate
Inventor: IZAWA NOBUYUKI
IPC: H01L21/324
Filed: 1986-10-02
Abstract: PURPOSE:To obtain an N-type semiconductor substrate of high resistivity by a method wherein a P-type semiconductor whose resistivity is more than 1000OMEGA.cm and whose oxygen concentration is 2 X 10<17>-1 X 10<18>/cm<3> is heat-treated at 400-500  deg.C and oxygen contained in the semiconductor is transformed into a thermal donor so that a P-type impurity can be removed. CONSTITUTION:If, among a radiation-detecting device, a photodetecting device, a high breakdown strength semiconductor-device or the like, an N-type semiconductor substrate of high resistivity is to be obtained by heat-treating this substrate at a comparatively low temperature, the following procedure makes it possible to manufacture the substrate at a good yield rate and at a low cost. For example, a P-type Si single crystal whose resistivity is 1500OMEGA.cm is processed by a Czochralski method and this crystal is sliced to form an Si substrate. This substrate is heat-treated at 450  deg.C to obtain an N-type substrate with a resistivity of 5000OMEGA.cm. In this case, the initial acceptor-concentration of the starting substrate is about 9 X 10<12>/cm<3>, and the donor concentration of the substrate which is finally transformed into the N-type substrate is about 8 X 10<11>/cm<3>. This means that, because the donor concentration is given by oxygen, it is sufficient for a donor to have a concentration of 9 X10<12> + 8 X 10<11> = 9.8 X 10<12>/cm<3>.

Title: Manufacture of foamed product with core material
Inventor: NAKAJIMA AKIRA
IPC: B29L9/00
Filed: 1987-09-18
Abstract: PURPOSE:To make it possible to favorably discharge residual air and blowing gas in foam space by a method wherein specified air-permeable sheet is employed as coating sheet so as to be coated on a core material at the side, on which foam layer is formed or is not formed. CONSTITUTION:Under the state that a foam molding mold 26 consisting of a top force 22 and a bottom force 24 is open, a skin 12 is set on the inner surface of the bottom force 24 and a core material 14 is set on the inner surface of the top force 22. An air-permeable sheet 30 is coated on the surface, which is positioned inside the foam molding mold, of the core material 14. The air- permeable sheet 30 has open pores or open cells, which permeate gas and suppress the passing of foaming material to the degree of oozing-out so as not to make any trouble on a product under the degree of the pressure to be applied during foaming operation. Due to the permeation inhibitory function to foaming material of the air-permeable sheet 30, urethane is prevented from leaking. In addition, due to the permeation permissive function to gas of the air- permeable sheet 30, the residual air and developed gas are effectively discharged out of the foam space.
