Filed: 1985-07-29
Abstract: PURPOSE:To obtain an Al-Si-Fe-Ni heat- and wear-resistant aluminum alloy having improved toughness and elongation by incorporating specific percentage of Si, Fe and Ni to Al. CONSTITUTION:In the Al alloy containing Si, Fe and Ni, Si content and the total amount of Fe and Ni (Fe+Ni) are regulated to 50-40wt% and 2-12wt%, respectively, the ratio of Fe to Ni is also regulated to 1:4-4:1 and the balance consists essentially of Al. The alloy having the above composition is cooled rapidly at >=100 deg.C/sec rate of solidification to regulate the sizes of intermetallic compounds and precipitates to <=50mu and then formed by hot extruding. In this way, the Al alloy improved in toughness and elongation without causing too much deterioration in wear resistance as well as heat resistance can be obtained.

Title: Calling detection system of telephone terminal
Inventor: SHIRAI SEIICHI
IPC: H04Q3/72
Filed: 1982-09-29
Abstract: PURPOSE:To reduce the power consumption, by detecting the off-hook of a handset at the telephone terminal side as a call through the detection of presence of an optical signal from a telephone terminal connected with an optical fiber at the station side so as to decrease the output state of light source at the station side. CONSTITUTION:A mirror 18 of an optical switch 17 is interlocked with a hook switch 4 and an optical pulse for call detection from a station is reflected or transmitted with the movement of the mirror 18. When the handset is at the on-hook state, the mirror 18 is positioned between ''SELFOC'' lenses 19 and 20, reflects an optical pulse for calling detection at the station side and transmits the light to the optical fiber 15 through the lens 19. The mirror 18 is interlocked with a hook switch 4 at the off-hook state and shifted so as not to be positioned between the lenses 19 and 20, and the optical pulse for calling detection passes through the lens 20 and is made incident to a light emitting element 14. T he optical pulse reflected at the light emitting element and returend to the station side is made sufficiently smaller than the reflecting pulse of the mirror 18, the station side discriminates the two kinds of reflecting lights and discriminates the off-hook state.

Title: Plasma display panel and manufacture thereof
Inventor: KIMA YASUNORI
IPC: H01J11/38
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a plasma display panel having addressing electrodes which can be manufactured at low cost without requiring a complicated process. SOLUTION: In a plasma display panel having addressing electrodes 9 to select lighting on and off of respective display cells in the front face plate or the rear face plate, the addressing electrodes 9 are formed from a Ni-B alloy film deposited from an electroless Ni coating solution using a boron compound as a reducing agent. Normally, since lighting information for a plurality of cells is not simultaneously supplied to the addressing electrodes, large current does not flow in the electrodes and the surface resistance value 0.5-20EΩ or lower is sufficient, so that thick film forming printing is not necessarily needed and a thin film coating layer can sufficiently satisfy the conditions.  There are many kinds of materials usable for electroless coating, the Ni-B alloy has an advantage from the overall view point of film formability, easiness of patterning, conductivity, heat resistance, and cost.

IPC: H04N19/91
Filed: 1991-06-14
Abstract: PURPOSE:To curtail an image data accumulation memory in the plotting device by executing a divided transfer from a host device, at the time of plotting image data of a large capacity. CONSTITUTION:The plotting device is formed by dividing it into a printer controller part 1-1 and a printer engine part 1-2. At the time of executing a divided transfer, an identifier for showing which of the head data, the intermediate data or the final data the transfer data is put to the header part of compressed/ encoded data which is transferred. The plotting device side for dividing and receiving its data discriminates the transferred compressed/encoded data by the head identifier, and executes a plotting expansion at every compressed/ encoded data. In such a state, in the case of becoming below the number of bits determined arbitrarily in the course of execution of the plotting expansion by the divided reception, the plotting expansion is suspended and the remaining bits are accumulated on a memory. Also, in the case of executing the plotting expansion by the divided reception, first of all, the plotting expansion is executed by placing the compressed/encoded data by the divided reception after the remaining bits accumulated on the memory, and plotting continued from the plotting expansion plotted previously is executed.

Abstract: PURPOSE:To have proper and flex anticipation of plane meeting 'by grasping the relative position relationship between a plane concerned and any plane as target using fuzzy control. CONSTITUTION:In a simulation flight system, in which the meeting point of a plane concerned 12 with any plane as target 11 can be anticipated, the target plane 11 continues to be in constant sped linear motion with no change in its current attitude. It is assumed, therefore, that the velocity vector Ve of the target plane 11 does not change, while an assumption is made for the plane concerned 12 so that its heading and path angle can be modified (altered) instantly. The relative position relationship between the two planes 11, 12 is grasped by fuzzy control, nd the plane meeting point in the stabilization axis coordinates system of the target plane 11 is determined from the position, velocity and attitude of the target plane 11 and the position and velocity of taxis plane concerned 12. This is followed by determining the heading modification angle (heading error) of the plane concerned 12 and its path modification angle (path angle error). The bank angle, incidence angle, and thrust force are controlled so that these two errors nullify.
