Title: Detector for broken tool edge
Inventor: NAKANO MINORU
IPC: G01N29/14
Filed: 1981-05-06
Abstract: PURPOSE:To detect a defect at the edge of a cutting tool to maintain accurate machining operation of an unmanned machine tool by comparing the change in voltage in closed electric circuit closed when the tool edge is brought in contact with the work to be machined and the change in number of AE counts per unit time of the AE signals. CONSTITUTION:An electric closed circuit is established when the tool edge 2 comes in contact with the work 1 to be machined with the contact point 4 on. The change in current due to contact between the tool edge 2 and the work 1 is detected by a resistance 5, and the current change signal issured therefrom is converted into a change in voltage at a discriminator 14. The acoustic emission signals (AE signals) are detected by a detector 10, and the number of AE counts is converted into the number of change per unit time at the discriminator 14. By plotting these changes with the cutting time on the axis of abcissas, both a voltage drop and the AE signals are seen generated when the tool edge is broken, a rise in voltage and the AE signals when cut chips are stuck around the tool edge, and a voltage drop but no AE signal when cutting oil enteres between the tool edge and the work. Thus, the type of damage of trouble can be known to some extent.

Title: Optical receiving device
Inventor: MACHIDA SHINICHI
IPC: H04B10/69
Filed: 1994-04-07
Abstract: PURPOSE:To provide an optical receiving device which can correct the peaking of frequency characteristic caused by a parasitic inductor and the parasitic capacity by connecting a coil, a capacitor and a resistance in parallel to each other at the post stage of a preamplifier. CONSTITUTION:A resonance circuit consists of a coil 4, a capacitor 4 and a resistance 6 at the post stage of a preamplifier 3. When an optical signal is inputted to a photodetector 1, a current flows to the photodetector 1 in response to the optical level. This current is taken out by a bias resistance 2 as an electric signal and amplified and outputted by the preamplifier 3. The impedance of the resonance circuit is maximized by the resonance frequency defined by the coil 4 and the capacitor 5, and the level of the resonance frequency is decided by the resistance 6. The amplitude of the output signal received from a terminal 10 is reduced at a level close to the resonance frequency owing to increase of the impedance of the resonance circuit. Thus it is possible to correct the parasitic capacity of the photodetector 1 and the peaking of an inductor and to flatten the frequency characteristic by giving the characteristic adverse to the peaking of the photodetector 1 to the resonance circuit.
