Patent JP-S641083-A (JP)
Title: Object image synthesizer
Inventor: NEMOTO KEIJI
IPC: G06T15/80
Filed: 1987-06-23
Abstract: PURPOSE: To simplify the change processing of an area shape for the re-distribution of a load, by forming a spatial area in charge of each luminance calculation part with the rectangular parallelopiped of a plane perpendicular to an axis of coordinate, and changing the area by moving a boundary plane in parallel with the axis of coordinate corresponding to the load.  
     CONSTITUTION: The area in charge of the rectangular parallelopiped formed with the plane perpendicular to the axis of coordinate is allocated to each luminance calculation part which decides luminance based on crossing between a beam of light passing an image element from a view point and an object, and area information is stored in an initial area storage part 40. Meanwhile, the load is decided by a load deciding means 43, and the maximum and the minimum load in six adjacent boundary planes are selected, and the expanding and reducing directions of the area are decided by a direction deciding means 44. Next, an expansion deciding means 45 compares the load of the calculation part 3 with the maximum load of an adjacent calculation part from the means 43, and when deciding the necessity of expansion, expands the area by moving the plane in parallel with the axis of coordinate corresponding to the direction decided by the means 44. The reduction of the area is performed similarly, and since the apex of the rectangular parallelopiped is not set as reference, it is possible to simplify and perform the change of the area surely and to heighten the effect of the re-distribution of the load.

Title: Positioning device
Inventor: DOI MAKOTO
IPC: G05D3/12
Filed: 1991-06-27
Abstract: PURPOSE:To provide a positioning device with high stability even in an area having the problem of vibrations such as disturbance in the gain of velocity feedback in an extremely low speed state or a stopping state. CONSTITUTION:Difference between the target timing value of position movement from a software processing part 1 and the current position of a counter 10 depending on signals from an encoder 7 to detect the revolution of a motor 6 is amplified by a position loop amplifier 3 and outputted, and speed signals from a speed preparation circuit 8 are amplified by a variable gain speed feedback amplifier 19 and outputted. Difference between both outputs is amplified by a speed loop amplifier 4 and transmitted to a driver 5, and the motor 6 is driven. Thus, the software processing part 1 calculates the level of difference between the current position and the target timing value of the position movement, and the gain of the variable gain speed feedback amplifier 19 is switched to a larger gain when this difference is larger than a fixed value or to a smaller gain when the difference is smaller.

Title: Accelerator for electric motor vehicle
Inventor: TSUKIYAMA TADASHI
IPC: H02P29/00
Filed: 1977-12-26
Abstract: PURPOSE: To eliminate overrun of an electric motor vehicle even when a controller is disconnected in wires by using a control circuit such as an oscillator interlocked with an acceletator pedal, amplifier, variable reactor, rectifying circuit, inversion smoothing circuit or the like.  
     CONSTITUTION: The signal from an oscillator OSC is fed through an amplifier A 1 , a variable reactor VL interlocked with an accelerator pedal, a diode D 1  and an inversion smoothing circuit INS to provide a motor control signal from a terminal Vo. Since the input signal of the circuit INS is negative half-wave rectification signal and an electric circuit including the accelerator is energized by a battery as a power supply, no lower potential than the ground GND is applied to a control circuit. Thus, even if a disconnection of wires or like fault occurs at the reactor VL, the output of the circuit INS does not become high potential and, accordingly, an electric motor vehicle does not overrun.

Title: Fabrication of mask rom
Inventor: TAKAO YUKIHIRO
IPC: H01L27/112
Filed: 1993-06-28
Abstract: PURPOSE:To rationalize a fabrication process by achieving the formation of a protective film just after ion implantation by etching a layer insulating film taking an Al wiring as a mask and selectively implanting impurity into a channel region of a memory cell transistor. CONSTITUTION:On the surface of a semiconductor substrate 11 bit lines B are formed and further word lines WL, a silicon nitrided film SN, and a layer insulating film 12 with a reduced pressure CVD process. An Al wiring 13 is formed by sputtering and patterning Al over the entire surface of the substrate. The layer insulating film 12 is etched with use of the Al wiring 13 as a mask and a channel region CH of a memory cell transistor MT is rendered to selective ion implantation. A protective film 14 is formed so as to cover the semiconductor substrate 11. The layer insulating film 12 is etched using the Al wiring 13 as a mask in such a manner whereby a region where the layer insulating film 12 is removed is widened and hence no 'cavity' is produced even when the protective film 14 is formed at once.

Abstract: PURPOSE:To enable to use as the fuel of a boiler coal containing high iron content without the occurrence of slagging, by a method wherein burners at plural stages are installed, coal containing high iron content is fed to the burner at a lowermost stage, and the burner at the uppermost stage takes the form of a denitrificating burner. CONSTITUTION:Burners 2, 3 and 4, positioned at the lower part of a boiler furnance 1, are aligned in 3 stages, the burners 2 at a lower stage and the burner 3 at a middle stage form a main burner, and the burner 4 at an upper stage forms a denitrating burner. Coal containing high iron content contained in a banker 5 is the coal which has the amount of iron in ash being 10% or more in consideration of the softening and the melting temperature of coal ash. Coal containing high iron content, pulverized by a mill 7, is fed to the burner at the lowermost stage through a fuel pipe 13 by an air fan 12 to charge it into the furnace 1. In the burner 2 at the lowermost stage, an air ratio is set to 1.0 to form an oxidizing atmosphere. Thus, ash content is prevented from softening and melting as in a reducing atmosphere. Meanwhile, in the burner 4 at the upper stage, an air ratio is set to 0.8 or less, whereby a reducing atmosphere is produced and a boiler is capable of achieving low NOX combustion.
