摘要:
A work machine includes a main pole internally including a rotation shaft, a tool unit located at one end of the main pole, and a power unit located at another end of the main pole. The main pole includes a first partial pole, a second partial pole and a joint member that joints them to each other. The first partial pole includes a positioning member. The joint member includes a positioning hole configured to engage with the positioning member and a guide groove extending from the positioning hole. The guide groove is configured to guide the positioning member to the positioning hole and to allow the positioning member to escape in at least a section thereof.

A piezoelectric acoustic component includes a diaphragm having a substantially rectangular piezoelectric plate including front and back surfaces, an electrode disposed on the front surface, a substantially rectangular metal plate bonded to the back surface of the substantially rectangular piezoelectric plate directly or via an electrode disposed on the back surface of the substantially rectangular piezoelectric plate, an insulating cap having an upper wall, four side walls extending from the upper, a pair of support members arranged to support the diaphragm at the inside of the two of four sides walls opposed to each other, and a plate shaped substrate having a first electrode section and a second electrode section. The diaphragm is disposed the insulating cap. Two of four side edges of the diaphragm are opposed to each other and fixed to the pair of support members. A gap is formed between the other two of four side edges of the diaphragm and the cap and is sealed by elastic sealing material. An acoustic space is provided between the diaphragm and the upper wall of the insulating cap. An opening edge of the four side walls of the insulating cap is bonded to the substrate. The metal plate is electrically connected to the first electrode section. The electrode disposed on the front surface of the substantially rectangular piezoelectric plate is electrically connected to the second electrode section.

This invention concerns a sintered article for a sheath in an apparatus for continuous casting of a thin sheet and a sheath using the sintered article. The sintered article comprises boron nitride, zirconium oxide, and at least one member selected from the group consisting of aluminum nitride and aluminum borate and combines resistance to thermal shock, lubricity, and strength. The sheath is formed of the sintered article and, therefore, enjoys the prominent properties of the sintered article.

Experiential gradation correction curves for sample images are prepared. By analyzing the experiential gradation correction curves and accumulated density histograms of the sample images, two points (Y.sub.1, Q.sub.1) and (Y.sub.2, Q.sub.2) are specified, where Y.sub.1 and Y.sub.2 are values of accumulated occurrence and Q.sub.1 and Q.sub.2 are halftone dot percentages for image reproduction. The values Y.sub.1 and Y.sub.2 through an accumulated density histogram of an original image whose gradation is to be corrected. A gradation correction curve Q=G(x) is determined so as to pass through the two points (x.sub.1, Q.sub.1) and (x.sub.2, Q.sub.2).

Highlight density (X.sub.H) (or shadow density) is established on the basis of a cumlative histogram (H(X)) of density of an original. Computed first are reference densities (X.sub.HR, X.sub.HL and X.sub.Hl -X.sub.Hn) associated with prescribed reference statistic values (Y.sub.HR, Y.sub.HL and Y.sub.Hl -Y.sub.Hn), respectively, and threshold values (W.sub.Hl -W.sub.Hn). Then, the reference density (X.sub.HR) is compared with a prescribed threshold density (X.sub.HS), and a difference (X.sub.Hi) concerning the reference density (X.sub.Hi) is compared with the threshold value (W.sub.Hi) in a procedure, to thereby select one of procedures for establishing the highlight density.
摘要:
A character drawing method for use in a bit map display system in which after sentence data constituted by character code data have been converted into character pattern data, a bit string for forming characters is transferred to a memory for display corresponding to pixels so as to be displayed. In the character drawing method, drawing of the characters is performed through optimum distribution of functions of processings to be executed such that the processings are executed in parallel by a multiprocessor.
摘要:
A standard gradation correction curve independent of characteristics of an original image is prepared in advance. An accumulated density historgram curve of the original is obtained from image data of the original. A first gradation correction curve is obtained by modifying the standard gradation correction curve, while a second gradation correction curve is obtained by modifying the accumulated density histogram curve. A third gradation correction curve is obtained by linear combination of the first and second gradation conversion curves to perform gradation correction of the image data on the basis of the third gradation correction curve.
