Abstract: PURPOSE:To deburr surely and easily a casting by pressing a blade member to the casting and clamping the casting from both sides in the direction parallel with the pressing direction of the blade member then pressing the blade member to cut the flash of the casting. CONSTITUTION:A robot arm 4 is driven to move a deburring tool 6 in such a manner that the burr 2 advances horizontally into the space between the edge 10e of the blade member 10 and a positioning part 10f.

The blade member 10 is pressed downward by piston rods 16, 19, 21 to notch stepwise the burr 2 from the outside until the burr is cut down to the root. The sure and easy cutting of the burr of the casting is thus made possible by using the robot having the relatively weak supporting power.

Filed: 1982-05-20
Abstract: PURPOSE:To detect a fault of an output independently, by connecting plural input and output buffers connected to an internal logical element successively in series through selecting circuit in a loop, and causing self-oscillation. CONSTITUTION:The selecting circuits 6 are provided between plural input buffers 2 and output buffers 3 connected to the internal logical element 1, and the selecting circuits 6 select test or normal mode under the control of a control circuit 7.

When the test mode is set by the control circuit 7, the input and output buffers 2 and 3 are connected in series alternately to form a loop, which enters into a self-oscillation state. If some buffer is faulty, the oscillation is not performed. Further, the delay time is tested by measuring the oscillation frequency. Thus, the buffers are checked independently of the internal logic element and made into an integrated circuit suitably.

Title: Optical head
Inventor: DOI AKIHIKO
IPC: G02B7/00
Filed: 1985-04-23
Abstract: PURPOSE:To dispense with a driving device for shifting in two directions and to simplify the structure and adjustment by providing a luminous flux changing device that changes the state of divergence and convergence of luminous flux that passed a collimating device shifting a light source. CONSTITUTION:In focused state, if the state of flux L of laser light that passed a collimating lens 23 is set to parallel luminous flux, flux L of laser light that passed the collimating lens 23 becomes the state of convergence when a semiconductor laser 21 is put away from the collimating lens 23, and flux L of laser light that passed an objective 25 is converged at a position near the objective 25. When the semiconductor laser 21 is brought near the collimating lens 23 becomes the state of divergence, and flux L of laser light that passed the objective 25 is converged at a position off from the objective 25. That is, by making tracking with a converging device and making focusing with the light source, a driving device for shifting in two directions becomes unnecessary, and the structure and adjustment become simple.

Title: Optical repeater
Inventor: TAKEMURA NOBUYUKI
IPC: H04B10/293
Filed: 1992-04-07
Abstract: PURPOSE:To provide a function to demodulate and extract a first monitoring a signal and to transmit the main signal light by superimposing a second monitoring signal with the same frequency as that of the first monitoring signal. CONSTITUTION:An optical demultiplex coupler 4 demultiplexes the main signal light (c) on which the first monitoring signal (a) from a signal light input terminal 1 is superimposed. The optical level of the main signal light (c) is changed since it is intensity-modulated by the monitoring signal (a), therefore, a receiver 5 performs optical/electrical conversion on the level, and extracts the first monitoring signal (a). An excitation light source driving circuit 8 inputs the excitation light (e) of an excitation light source 9 to the rare earth doped optical fiber 3 while controlling the output level of it. The amplified light (h) in which th optical level of the main signal light (c) is uniformalized can be outputted by inputting the excitation light (e) by performing such control so as to set a level error signal (g) at negative phase against the first monitoring signal (a). Also, the second monitoring signal (b) is generated from a monitoring signal generation circuit 13, and signal light (d) on which the second monitoring signal (b) is superimposed is transmitted.

Filed: 1980-06-26
Abstract: PURPOSE:To correct shading, by comparing the output of an envelope detector with the reference signal, then negative-feeding back the result of comparison to a gain control type amplifier, and picking up a compensated output signal. CONSTITUTION:When a signal IN in which the level of the center A is high, the level of both ends B, B' is lowered, and the locus of the waveform of upper end draws an envelope, is inputted to an envelope detector 2 via a gain control type amplifier 1 by shading, an envelope signal V2 is outputted from a detector 2.
