Title: Method of generating dc arc
Inventor: NARISEI TORU
IPC: H05B7/18
Filed: 1992-05-15
Abstract: PURPOSE:To stabilize arc when the arc is extended by generating the arc while sucking the atmospheric gas on a hollow electrode top end side through the core hole of the electrode. CONSTITUTION:A hollow electrode having a core hole 3 in the shaft center part is used as an electrode 1, and the inner part of the core hole 3 is sucked from the base end side by a pump 5 or the like, whereby an arc A is generated while sucking the atmospheric gas on the electrode top end side. Since a negative electrode point C can be restricted on the inner surface of the core hole 3, electrode point movement on the electrode side is eliminated, and instability of the arc A is reduced. Further, since the negative electrode point C is situated in the electrode, the sectional area change of the arc column is not so large as that near the negative electrode point, and the generation of plasma gas current is also reduced on the electrode side to reduce the instability of the arc. Preferably, the sucking gas quantity is 3-5m<3>/min, and the bore of the core hole is 50-90mm.

IPC: B22F9/10
Filed: 1992-05-15
Abstract: PURPOSE:To increase the yield of the globular metal fine particle by the rotary disk atomization method and enhance the economics thereof by specifying the temp. of the molten metal or alloy. CONSTITUTION:The temp. of the molten raw metal or alloy is kept higher than the m.p. of the metal or alloy by 50-200 deg.C or preferably by 80-150 deg.C, and the melt is atomized. Consequently, the wettablity of the rotary disk with the melt is improved, a uniform melt film is formed on the disk, the melt film is not waved, and the production of a large-diameter liq. droplet resulting from breakage is not caused. As a result, the yield of the globular metal fine particle is increased in the rotary disk atomization method.

Title: Controller for inverter
Inventor: MIKI OSAMU
IPC: H02M1/00
Filed: 1992-06-09
Abstract: PURPOSE:To realize smooth emergency stop through such control as indicating and processing method is switched at the time of operation based on a signal for switching operation/stoppage through an operating means and emergency stop can be carried out through the operating means even when operation/stop can not be carried out through the operating means. CONSTITUTION:Upon actuation of an operating key 35e, a microcomputor(MC) 33 checks operation mode and in case of setting operation section command mode, a command for clearing the operation command is delivered to MC 25 thus stopping an inverter unit. In other case, no signal is delivered to the MC 25 but an indication for confirming emergency stop is given on an indicator 37. When an operation key 35e is operated under that state, the MC 33 delivers an emergency stop signal to the MC 25 and executes emergency stop of inverter unit thus making possible to execute emergency stop from setting operation section even during automatic operation of inverter unit when operation/stop can not be carried out from the set operation section.

Title: Foreign substance inspection apparatus
Inventor: SHISHIDO HIROAKI
IPC: G03F1/84
Filed: 1986-06-27
Abstract: PURPOSE:To enable detection of a foreign substance which scatters light so feebly that it cannot be discriminated from a pattern, by extracting a pattern edge portion from a transmitted light detection signal of a sample and discriminating light scattered by a foreign substance from said signal. CONSTITUTION:A pattern edge extracting circuit 23 processes a transmitted light detection signal and extracts a pattern edge on a photomask from said signal. A foreign substance dlscriminating circuit 24 removes a scattered light detection signal from the pattern edge from a detection signal supplied from a scattered light detection section 16 and determines whether any foreign substance is detected or not based on the data of said pattern edge. In this manner, minute foreign substances can be detected indenpendently from scattered light from the pattern edge. A flat-type foreign detection circuit 30 differentiates a detection signal given by illumination of transmitted light to emphasize the edge portions of a foreign substance if any and determines whether a foreign substance is detected or not.

IPC: H04L25/02
Filed: 1985-07-08
Abstract: PURPOSE:To eliminate necessity of providing an AC power equipment in a slave station and reduce the cost of equipment by transmitting alternating signals for electric power from a master station to a transmission line and making a slave station obtain DC power source basing on the alternating signals for power. CONSTITUTION:A master station 1 is made to output alternating signals Sa..., Sb... in addition to reset pulse P0, count pulses P1-P5 to transmission lines La, Lb.

IPC: H04N1/32
Filed: 1991-05-23
Abstract: PURPOSE:To attain a restoration to a normal transmission sequence in an FSK mode even when a synchronism is lost due to the intrusion of a noise on the transmission of picture data in a high speed MODEM mode, at the time of the transmission of the picture data by an ECM communication. CONSTITUTION:When the synchronism is lost due to the incapability of the reception of a synchronizing flag included in a frame on receiving the picture data for each block constituted of plural frames in the high speed MODEM mode, the high speed MODEM mode is forcedly switched to the FSK mode in order to wait the reception. Afterwards, at the time of receiving a transmission confirmation request signal at the tail of the picture data of one block, which is transmitted from a transmission side in the FSK mode, a retransmission request signal is transmitted to the transmission side in order to request the retransmission of the frame which can not be correctly received.

IPC: G06F3/038
Filed: 1992-06-09
Abstract: PURPOSE: To improve the processing speed of a cursor processing circuit by performing cursor data processing for displaying the data on the screen of a monitor by hardware. CONSTITUTION: The position designating section of a cursor processor processes cursor signals displayed on the screen of a monitor together with video signals. A reference position generator 200 generates the positional information by sections of the screen. A position control signal generating section 220 generates X- and Y-axis active sectional signals for setting the displaying position of a cursor upon receiving position designating information and the positional information by sections. The cursor data which are generated by means of a cursor data generating section upon receiving the Y-axis active section signal are arranged on the screen at the position designated by the X- and Y-axis active section signals by a cursor data arranging section 230. The arranged cursor data are inserted into video data by a data inserting section 240.  Since the cursor data are processed by hardware, the processing speed of the cursor processor is improved.

Abstract: PURPOSE:To approximate the image data to the image of an original picture by providing a mosaic matching processing part to select an optimum mosaic pattern in order to increase the consistency at the time of the mosaicing process of small blocks adjoining to small mosaicly processed blocks. CONSTITUTION:When image data 1 is divided into small blocks, collated individually with a mosaic pattern dictionary 2 to make mosaic, based on one- dimensional image information in the X or Y direction of the edge surface, in which a continuously mosaic-made mosaic is connected to already mosaicly processed small blocks, a mosaic pattern matched with it is selected. When small continuously connected blocks are collated with a mosaic pattern dictionary, the blocks are collated with the candidate of earlier selected mosaic patterns and the mosaic pattern consistent with two-dimensional elements in X and Y directions is selected. Thus, the consistency between mosaics is improved, and the image data can be made mosaic by the smooth segment approximate to the image of the original picture.
