Title: Positioner mechanism for light beam storage device
Inventor: TSUKADA EIICHI
IPC: G11B7/085
Filed: 1980-10-15
Abstract: PURPOSE:To make the device small-size, light-weight, and cheap, by mounting one light control optical system on positioners and joining and separating the head positioner and the recording positioner to switch the recording mode and the reproducing mode. CONSTITUTION:In the reproducing mode, a head positioner 3 is moved in directions of arrows A and B selectively in a high speed intermittently through a guide 4 by a motor to move a light control optical system 1 to the object position. In the recording mode, a steel ball 2 is joined with a feed rod 5 to join a recording positioner 6 and the head positioner 3 under the state where a constant current is flowed to a driving motor for the head positioner 3 to give a constant acceleration. The light control optical system 1 is then moved to the object position by a high-precision feeding of a screw feeding mechanism 7. Thus, the device is small-size, light weight, and cheap.

Title: Adjusting method for cutting speed of cutter and device thereof
Inventor: NAGAHIRO MASAJI
IPC: B23D55/08
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To adjust a cutting speed to a proper speed at all times according to the change in temperature of an actual working fluid. SOLUTION: The cutter is provided with a fluid pressure cylinder 41 making a saw blade housing 5 (tool housing) bearing a saw blade freely rotatably approach and recede from a work and a flow rate control valve 57 controlling the flow rate of a working fluid operating this fluid pressure cylinder 41. Data of the correlation of the opening degree of the flow rate control valve 57 and flow rates is preliminary stored in a memory 71 for every several set fluid temperatures.  Even if a change is generated in the temperature of the working fluid supplied to the fluid pressure cylinder 41, the values of the opening degree of the flow rate control valve 57 and the flow rate for the temperature of the actual working fluid are calculated by an arithmetic unit 73, based on data of the correlation of the opening degrees of the flow rate control valve 57 and the flow rates in two high and low set fluid temperatures for the temperature of the actual working fluid. As a result, a proper cutting speed for the work can be always obtained because the opening degree of the flow rate control valve 57 is adjusted to supply an optimum flow rate to the fluid pressure cylinder 41.

Filed: 1988-06-09
Abstract: PURPOSE:To standardize the fault position of an optical cable from a terminal station to a standardization possible distance by means of an OTDR system by permitting a standardization signal to bypass an optical repeater in a repeating installation. CONSTITUTION:At the time of normal optical cable communication, a controller 5 connects the output side of the optical repeater 2 with the optical cable 13 by an optical switch 4, and main signals which are transmitted from the terminal station 10 and which are inputted from the repeater in a preceding stage are waveform-shaped/amplified by the repeater 2. When the OTDR fault position is standardized, the alternating current of a frequency f1 in a control signal generation means 11 is superimposed on the feeding voltage of a feeder 12, is transmitted and it changes over the switch 4 on the side of a through fiber 3 through the controller 5, whereby a measurement instrument 20 receives the standardization signal to be transmitted and a return signal due to the back scattering of the fault so as to standardize the fault position. A frequency f2 is transmitted, the switch 4 is changed over and a system is returned to a normal state after the termination of standardization.

Abstract: PURPOSE:To prevent the occurrence of defective marking and to reduce a time required for adjustment of a distance and measurement, by detecting automatically the distance of a marking mechanism from a surface to be marked, and by giving an alarm when a gap is made between the value thereof and a set value. CONSTITUTION:A means to detect the distance between a surface to be marked and a marking mechanism is provided, and when a gap is made between the distance and a set value, an alarming means is made to operate according to an instruction from the detecting means. Concretely, the characteristic of a circuit element on a stage 2 is measured by a probe needle 3, and when said element is determined as defective, a discrimination mark is given thereto by a marker 4. Defective marking is eliminated by making appropriate the distance between the marker 4 and the surface of a wafer 1 by means of a sensor 5. In the case when a detection value of a change in capacity becomes divergent from a set value, the sensor 5 sends its signal to an alarm 9 to make it operate for giving an alarm, while delivering a stop signal so as to discontinue a marking operation. This operation is started again after the distance between the tip of the marker 4 and the surface of the wafer 1 is adjusted to accord with the set value.
