Title: Automatic detector of boring surface
Inventor: WAKAMATSU KAZUHIKO
IPC: G05B19/18
Filed: 1983-02-04
Abstract: PURPOSE:To permit to control the driving of a main spindle by an electric signal by a method wherein a high frequency circuit is provided between a work driving table and a main spindle head to detect the difference of an inductance upon separation and contact between a working surface and a drill as a current or a voltage. CONSTITUTION:A discriminating comparator ICI, driven by the input of a voltage difference in which a threshold value to discriminate an amplitude is subtracted from the detecting output of a high frequency voltage at a discriminating threshold value setting circuit 10, functions so as to output the minute change of a high frequency oscillating voltage accompanied by the contact of the tool as the change of clear D.C. voltage. A light LED2 is lightened during a period wherein the tool is separated from the work while the light LED1 is lightened during the period wherein both of them are being contacted, whereby the relative positional relation between both of them is indicated. Thus, the contact between a machine tool and the work may be detected by the output voltage, therefore, the control of driving of the main spindle for a boring lathe or the like may be effected. Accordingly, an useless time after switching a feeding speed due to the change of the length of the drill or the position of the boring surface to the beginning of working may be minimized.

Title: Non-response transfer system of automatic private branch exchange
Inventor: KONDOU HIROYUKI
IPC: H04M3/42
Filed: 1984-02-02
Abstract: PURPOSE:To avoid a complicated operation by securing the connection to extensions of different end information with dialing of a numeric character in case a designated extension gives no answer. CONSTITUTION:When an extension A has a dialing operation to an extension B and the extension B gives no answer, the dial numeric characters are received by an originating register ORT and sent to a central controller CC.

Abstract: PURPOSE:To allow a spindle mechanism to attain stable rotating accuracy by fixing a bearing housing with the either one of an inner or outer ring as a reference, applying preload in a thrust direction so as to uniformly bring a bearing into contact with the inner and outer ring and assembling the spindle mechanism in that state. CONSTITUTION:First, the bearing housing 1 is fixed on an assembly jig 11 by a bolt 15, and an O-ring is put into the bearing fitting part of the housing 1 to apply an adhesive 17. Next the bearing 3b is put into an assembly jig 12 and fixed by an adapter 13 and a bolt 14 so that the inner ring of the bearing 3b will not move. While the adhesive 17 gets wet, the O-ring 10 is deformed between the housing 1 and the outer ring of the bearing 3b to lift the outer ring, and the bearing comes in contact with the inner ring. The adhesive 17 is dried in that state. After it dries, an upper side bearing assembly is removed out of the assembly jigs 11 and 12. It is assembled as a spindle mechanism, whereby its inner and outer rings come in contact with the bearing uniformly due to the force of a thrust preload spring 5.

Abstract: PURPOSE: To remove a cake efficiently from a cylindrical filter cloth in a backward washing and, at the same time, enable the filter cloth to be attached to cylindrical filter frames of various sizes by covering the cylindrical filter frame having perforations with the cylindrical filter cloth in a bellows fashion. CONSTITUTION: A cylindrical filter cloth 13 spreads as a cover on a cylindrical filter frame 12 with plural perforations12A in a bellows fashion according to the length of the filter frame 12. If a cake accumulates on the filter cloth 13 to clog the cloth 13, the filter cloth 13 is washed by removing it from the filter frame 12 or backward washed by injecting under pressure a cleaning water from the outer or the inner side of the filter cloth 13. In both of these cases, the cake sticking to the surface of the filter cloth 13 scales off by stretching/ shrinking and fluctuating the filter cloth 13 applied as a cover to the filter frame 12 in bellows fashion. In aaddition, the cake is removed from the filter cloth 13 by the pressure of the cleaning water.  Consequently, the cake accumulating on the filter cloth 13 is easily removed, and filter media of various sizes with the same filtration area are obtained by properly selecting the sizes of the filter frame 12.

Title: Method and device for processing image
Inventor: MOROZUMI YUICHI
IPC: G06T11/00
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To prevent the degradation of plotting performance by stopping the transmission of attribute data and a graphics command to a graphics processor, of which load exceeds a threshold, and distributing the attribute data and the graphics command to the other graphics processor. SOLUTION: First to fourth geometry engines 21-24 respectively calculate their own loads of geometry processing from the attribute data and the graphics command transferred from a command distributor 10. Besides, high load signals HL1-HL4 are outputted for showing whether the load of geometry processing exceeds the prescribed threshold by concentrating the graphics command or not. When the high load signals HL1-HL4 are detected, the command distributor 1O stops transferring the graphics command to the geometry engine until these signals are canceled. Thus, the attribute data and the graphics command are distributed to the other graphics processor.
