Title: Specific graphic generating circuit of crt display device
Inventor: FUJITA SATOSHI
IPC: G06T11/20
Filed: 1986-03-05
Abstract: PURPOSE:To eliminate the need for the repeating calculation of adding and multiplying and to increase processing speed by multiplying the data of determinant data to display a specific graphic and the determinant data for converting an image for enlargement and reduction and generating specific graphic data. CONSTITUTION:An ALU 21 prepares a determinant B for generating a circular graphic based upon circular graphic central coordinates and radius in a segment buffer 1. A matrix multiplier 38 multiplies a matrix for converting an image and the formula B stored at a matrix stack memory 37. Further, the ALU 21 makes a circular graphic approximate to a polygon, the value of an argument thetaof respective peaks is counted by an address counter 24, the address of a look-up table memory 23 is designated and the values of sintheta and costheta are read. These are stored to registers 32 and 33. Based upon the multiplying result of these values and the matrix, the multiplier 38 executes the calculation concerning respective peaks, when the calculation is completed, the calculating result is stored to an FIFO 39 and outputted to a clip processor.

Title: Segment generating circuit of crt display device
Inventor: ISHIDA KOICHI
IPC: G06T11/00
Filed: 1986-03-05
Abstract: PURPOSE:To omit an unnecessary coordinate conversion and a clip processing, to increase processing speed and to improve the through-put of a device by calculating the existence scope of a primitive included in a segment at a segment unit beforehand. CONSTITUTION:An ALU 21 reads primitive data in a segment header, calculates the maximum and minimum values and makes the average values into central coordinates. The distance between maximum values of central coordinates and X and Y coordinates is obtained as a radious (r) and stored into the segment header. When graphic data are displayed, a converting matrix is prepared from an image converting parameter, next central coordinates and the coordinates on the circular circumference expressed by the radius (r) are calculated, these are given to a multiplier 38 and the matrix multiplication is executed. The area surrounding the circular graphic described by central coordinates and a radius r' approximately adopted after conversion is made into the existence scope after the coordinates are converted, when the scope is in a display area, graphic data are converted, and when the scope is off from the area completely, the coordinate conversion and the clip processing of the graphic data are not executed.

Title: Reducing projecting exposure device
Inventor: KANEKO NORIO
IPC: H01L21/027
Filed: 1984-03-16
Abstract: PURPOSE:To execute precise positioning rapidly even when an exposure wavelength and an alignment wavelength differ by using an auxiliary lens and introducing a parallel plane glass as required. CONSTITUTION:A space between an original picture on a reticle 1 and a wafer 2 is kept accurately to a (g) line having an exposure wavelength. The image 8 of a pattern 9 illuminated by a (d) line having a wavelength for alignment is imageformed on the reticle 1 while being separated only by a distance rd. When an auxiliary lens 11 is arranged at a distance (b) in the lower section of the reticle 1 at that time, the image of the pattern 9 is image-formed on the reticle 1 as an image 8a. Consequently, positioning is enabled without vertically moving the wafer. When an (e) line is used for the auxiliary lens 11, the image of the pattern 9 for the wafer 2 does not reach the reticle 1 and is image-formed at a position at a distance epsilone from the reticle 1 as an image 8b because the wavelength of the (e) line is shorter than that of the (d) line. When a parallel plane glass 12 is inserted vertically to an optical axis for alignment between the reticle 1 and the auxiliary lens 11, the pattern 9 for the water 2 is image-formed on the reticle 1 as an image 8c.

Abstract: PURPOSE:To achieve low speed precision indexing and high speed rotation by providing a motor included in a casing of a rotation indexing table, connecting the indexing table directly with it, and performing rotation indexing for a low speed and a high speed by changing a rotation detecting means. CONSTITUTION:A motor 7 is composed of a stator 8 comprising a three-phase winding 8a fixed to a casing 2 and a stator iron core 8b, and a rotor 9 comprising a rotor winding 9a provided at a shaft 6 and a rotor iron core 9b. A rotation detecting means 11 at the shaft 6 detects a change of an excited voltage by a change of mutual positions between a first member 14 fixed to the shaft 6 and a second member 15 when an AC voltage is added to the second member 15 fixed to a casing 2 by an inductosyn, for example, and it is taken as a pulse by an A/D converter. The pulse generated by a rotation number of the first member 14 is changed for pulse generation in two stages or more including 9000 pulses/rotation to 0-400rpm, and 1024 pulses/rotation to 400-6000rpm, for example. An indexing table 3 is fixed to the shaft 6 by a bolt 16, so the rotation of the shaft 6 becomes the rotation of the indexing table 3 as it is.

Title: Probe for ultrasonic flaw detection
Inventor: SHIRAI TASUKU
IPC: G01N29/04
Filed: 1987-03-04
Abstract: PURPOSE:To improve flaw detecting sensitivity, reliability and the abrasion resistance of a wedge member by adhering a metallic thin film to the surface of one end of the plastic wedge member abutting against an ultrasonic vibrator in a housing at the other end, said surface being in contact with an object to be inspected. CONSTITUTION:An ultrasonic vibrator 2 in a housing 1 is obliquely located on a wedge member 3 made of a plastic and a cable 4 is connected to the vibrator 2. A thin plate 11 made of an austenitic stainless steel or cemented carbide is adhered to the whole surface 10 of the wedge member 3 in contact with an object 5 to be inspected. The thickness of the thin plate 11 is of the degree of 1/10-1/20 the wavelength of an ultrasonic wave in the object 5 to be inspected, though depending on a flaw detecting frequency and the like. Thus, since a sensitivity is improved, an in-wedge noise generated in the wedge member 3 with the improvement of the sensitivity is reduced and there is no or little abrasion of the wedge member 3, the life of a probe is improved and the necessity of recalibration due to the abrasion is removed.

Title: Reverse conducting 2-terminal thyristor
Inventor: HAGINO HIROYASU
IPC: H01L29/74
Filed: 1978-04-26
Abstract: PURPOSE:To make the breakdown voltage of diode region larger than the ON voltage of SCR and prevent commutation failure and diode breakdown by making the concentration gradient of the pn junction, which first and second semiconductor layers form, smaller in the diode region than in the SCR region. CONSTITUTION:In an SCR element 10a, a P type impurity is diffused in an N type substrate deeper in its diode region D than its SCR region to form a layer 11a, whereby a PN junction 17a is formed deeper in the substrate than 18. As a result, the impurity concentration gradient of the junction 17a is smaller than the junction 18a and therefore the breakdown voltage of the junction 17a becomes larger than the junction 18a. Hence, the SCR fires always before the diode region breaks down, thus firing failure and the diode region breakdown does not occur.

Abstract: PURPOSE:To improve sealing performance and durability by arranging a magnet on any of facing surfaces of a valve seat or a valve body in order to hold magnetic fluid and sealing the passing fluid by means of the magnetic fluid when a valve is closed. CONSTITUTION:A valve seat 13 having a through-hold 14 and a valve body 4 facing movably with the valve seat 13 are arranged in a valve box 1. An annular magnet 5 is arranged on a surface of the valve body 4 facing with the valve seat 13 so as to hold magnetic fluid 9. When a valve is closed, passing fluid is sealed by the magnetic fluid 9. When the valve is opened the valve body 4 is separated from the valve seat 13, then the magnetic fluid 9 is attracted by the magnet 5 in the valve body 4 and separated from the valve seat so as to provide a space between the valve body 4 and the valve seat 13 thus enabling passage of fluid. Consequently, passage of fluid can be blocked reliably by simply contacting the valve body 4 lightly against the valve seat 13, and the durability is also improved.
