IPC: G01C19/5621
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To provide a device of detecting the breading of wires capable of reliably determining the breaking of a pair of signal lines. SOLUTION: As a signal line 4 is separated from a charge amplifier 7, which outputs a voltage corresponding to an inputted signal, a detection signal B is not transmitted through the signal line 4 in the case of the breaking of the signal line 4, and a drive signal A being added via a resistor 2 instead appears in the signal line 4. In addition, a signal line 5 is not broken, and a detection signal C appears in the signal line 5. A differential amplifier 9 outputs a signal D of sufficiently high level enough to indicate the difference between the signals of the signal lines 4 and 5. An AC amplifier 10 amplifies a signal D and outputs a signal E. A signal F from a synchronous detector 11 becomes a DC signal of sufficiently high level, and a signal G from an integrator 12 becomes a DC signal of sufficiently high level.  A comparator 13 determines the breaking of the line 4 on the basis that the level of the signal G is higher than a positive threshold value.

Title: Machining method for optical parts
Inventor: USHIYAMA KAZUO
IPC: B24B13/00
Filed: 1992-11-12
Abstract: PURPOSE:To prevent abrasive grains of a machining tool from adhering on and engraving in the surfaces to be machined in grinding and polishing by separating the machined surfaces of an optical part while the machining tool is rotated. CONSTITUTION:After a specified time has been collapsed, a three-way solenoid valve 71 is opened by a controller 74 while an upper shaft is stopped to move and a grinding disk is rotating to suck a work to be machined 67. Also, a bellows hose 70 is contracted due to negative pressure, and supporting links 31 and 32, are pulled in vertical direction for positioning. When fixed abrasive grains are used for the grinding disks, the work to be machined 67 must be raised during the rotation of the grinding disks to prevent adhesive from attaching on the ground surfaces. In this case, because the supporting links 31 and 32 are positioned due to contraction of the bellows hose 70, the work to be machined 67 can be separated from the rotating grinding disks without run-out. Thus the work to be machined 67 is not be damaged.

Filed: 1989-12-18
Abstract: PURPOSE:To decrease the number of winding layers and diodes, and to obtain stable high-voltage pulses by halving the number of turns of the winding layer on the outermost or innermost side of a secondary winding or the winding layers on both sides of the winding layer and another arbitrary winding layer to an adjacent layer, positioning one end at the same position as that of the winding end of the adjacent layer and locating the other end at the position of the half of the number of turns of the adjacent layer. CONSTITUTION:One layer 2 of a secondary winding is positioned on the innermost side of a bobbin, and one end is positioned at the same location as that of an adjacent winding layer and connected to the anode of a diode 6 and the other end is connected to the midpoint (ground potential in this example) of AC potential at the intermediate location 2a of the winding width of the adjacent winding layer. The voltage of the intermediate section of the adjacent layer is fixed stably at midpoint AC potential i.e., DC voltage, and adjacent winding layers 3, 4... mutually induce high voltages having the same phase, and pulses vertically divided, with the intermediate position of the winding layers as a midpoint, are generated. The high-voltage pulses of approximately half of a conventional peak value are applied to each winding layer of the secondary winding, thus reducing an insulating distance, then decreasing the number of diodes and miniaturizing a flyback transformer.
