Title: Display device for luminance interpolation shading
Inventor: KANEMA SEIICHI
IPC: G06T15/80
Filed: 1987-04-09
Abstract: PURPOSE:To perform the effective luminance interpolation shading display with use of the hardware of a small scale despite a large number of display colors, by forming an approximate polyhedron so that it can display colors having gradations. CONSTITUTION:When an elliptical object 100 is displayed, the sample points Pi are set on the surface of the object 100 and set an approximate polyhedron consisting of many faces defined by those points Pi. Then the inner product value of the light source direction vector of a face apex and the normal line direction vector of a face or the angle value formed these two vectors is obtained. The linear interpolation is applied to said inner product value or the angle value so that the inner product value or the angle value of display points within a face is obtained. Then the red, green and blue components of the luminance corresponding to the inner product value or the angle value are obtained in terms of each display point. These color component values are stored in a frame memory and the contents of this memory are displayed on a CRT monitor. Thus the hardware scale is reduced for display many colors and variable density gradations.

Filed: 1985-04-22
Abstract: PURPOSE:To prevent the generation of harmful gaseous NOx from a pickling bath in the stage of pickling away the scale on the surface of a worked Ti product by pickling the Ti product while a prescribed value of residual compressive stress is made to remain on the surface layer part of the product. CONSTITUTION:Scale is formed by oxidation on the Ti surface during a heat treatment in the stage of working the Ti stock to a plate, bar or pipe material by heating, hot working, cold working and annealing treatment. The Ti material is pickled with a pickling soln. of 30-60 deg.C contg. 2% HF and 15-13% HNO3 to remove said scale.

Title: Oxygen sensor
Inventor: KOJIMA TAKAO
IPC: G01N27/409
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To provide an oxygen sensor which can commence measuring accurately within a short time just after the start of an engine. SOLUTION: A porous protective layer 70 abutting on a heating element 60 reaches a high temperature within a short time since the porous protective layer 70 is heated directly by the heating element 60. And, since H2 , CO, etc. in exhaust gas just after the start of an engine arrive at a porous measuring electrode 15 via the porous protecting layer 70 which is heated, and oxidized into H2 O and CO2 in the porous protective layer 70; an oxygen sensor 100 does not indicate λ shifting (stoichiometyricaly) due to the presence of H4 and CO. Thus the oxygen sensor 100 can measure the oxygen concentration accuretely immediately after the start of an engine.

Filed: 1985-04-22
Abstract: PURPOSE:To continuously and efficiently remove slag by blowing a gas carrying treatment material with an immersion lance into the molten metal in the tilted vessel and floating the formed slag by swirling flow. CONSTITUTION:A ladle 12 contg. molten iron 10 is placed on an inclined base 13 and is inclined to a prescribed angle; thereafter the immersion lance 14 is gradually lowered and gas is ejected therefrom.

The formed slag is floated and collected to the slag discharge side formed by the swirling flow generated by the blowing of the powder. The collected slag is continuously scraped out by moving a continuous slag scraping device 18 supported by a lifting device 16 to a prescribed position and rotating a scraping plate 20. The integral treatment of the molten iron and slag removal are thus made possible.

Title: Memory control circuit
Inventor: SHIROMIZU YASUBUMI
IPC: G06F12/00
Filed: 1989-04-05
Abstract: PURPOSE:To reduce one of two memory circuits required by a conventional method by waiting writing operation until reading operation is ended when the reading operation completes with the writing operation. CONSTITUTION:When reading timing and writing timing are superposed to each other, processing is controlled so that the reading operation is executed with priority and the writing operation is waited. Thereby, a control circuit 103 sends a write checking signal 07 after successively ending the reading operation and the writing operation without immediately sending the signal 07. Therefore, a write address signal 02 and a write signal 01 are extended with time from a dotted line to a solid line. Consequently, the reading and writing operation are executed without generating any trouble even when only one memory circuit is used.

Filed: 1992-04-08
Abstract: PURPOSE:To prevent the PROM incorporated microcomputer from being read by an outsider in the microcomputer provided with the built-in PROM. CONSTITUTION:This microcomputer is constituted so as to be provided with the PROM 11, an address decoder 12, a data storage circuit 13 to store the data of 8-bits read out of the PROM 11, a NAND circuit 15, and a protection circuit 14 including four OR circuits 16. Besides, original data length is made 4-bits, and the overhead bits of 4-bits are given to it. The original data and the overhead bits are arranged alternately, and total 8-bits are read out in accordance with one address. In the case that one bit among the overhead bits of 4-bits is logical '0', the protection circuit 14 outputs logical '1' all for the data of that address. Since the normal bits and the overhead bits are placed alternately, it is very difficult to erase only the overhead bits by the irradiation of ultraviolet ray, etc. Accordingly, it becomes impossible to read out a program.

Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To decrease the replacement frequency of a liquid crystal back light by judging whether liquid crystal needs to be illuminated and turning on the liquid crystal back light only when the liquid crystal needs to be illuminated. SOLUTION: An operation environment judging circuit 54 compares the use frequency of a keyboard 22 and a switch 24 judged by a use frequency judging circuit 36 with a previously set use frequency and, when the judged use frequency is larger than the set use frequency, judges that the liquid crystal back light 14 needs to illuminate the liquid crystal 10 since an operator views the liquid crystal 10 with light possibility. An operator presence/absence judging circuit 48 compares generated noise with a predetermined noise level and then judges that the liquid crystal back light 14 needs to illuminate the liquid crystal 10 when judging that the facilities are in operation. An interval timer 16 controls the lightness and lighting time of the liquid crystal back light 14 according to lighting periods and lighting times matching the individual cases.

Title: Power source for electric discharge machining
Inventor: FUTAMURA SHOJI
IPC: G05F1/08
Filed: 1988-04-08
Abstract: PURPOSE:To perform accurate servo control during electric discharge machining by a method wherein, during a period in which a gate pulse is brought into an OFF-state, a portion between two ends across a switching transistor produces resistance responding to conductance between gaps. CONSTITUTION:A plurality of resistors R1-R3 are connected in parallel to a switching transistor SW, and a voltage between the ends of the transistor SW and a line resistor R0 is generated as a detecting voltage Vs. Switching of a plurality of the resistors R1-R3 is effected in a way that conductance between gaps is predicted from the thickness of a workpiece 8 and a manual change-over switch S is switched. When the transistor SW is turned OFF, a short time and an open time can be clearly discriminated. The detecting voltage Vs is divided by means of resistors 6 and 7, and is compared with a reference voltage Vr into which the voltage value of a power source E is divided by means of resistors 4 and 5, and a comparing result is sent as a detecting signal to a servo circuit 2. When the detecting voltage is below the reference voltage Vr, an electrode 9 and the workpiece 8 are forced to approach each other, and in the inverse case, an approach motion is stopped.
