Title: Detecting device of tool breakage
Inventor: TAKINAMI KOJI
IPC: B23Q17/09
Filed: 1985-01-11
Abstract: PURPOSE:To improve reliability of detecting the breakage of tool by indicating abnormality of a sensor when a measured time until receiving a reflected wave which is obtained by giving a driving signal to an AE (Acoustic Emission) sensor at an interval of defined time, is above a time corresponding to the thickness of a sensor installing object. CONSTITUTION:A pulse signal is given to a transmitting part 31 from the pulse generator 30 of a sensor check circuit at every defined period while machining, to drive the wave sending piezoelectric element 7b of an AE sensor 7. Also, an AE signal is transmitted to a base 2, causing a reflected wave to be applied to a wave receiving piezoelectric element 7a when the wave is sent and after a certain period of time due to bottom reflection. This signal is given to a transmission receiving part 32 and, if there are wave receiving signals which are above a defined level due to a surface wave or a reflected wave, an output is applied to a gate circuit 33, and the clock of a clock generator 34 is transmitted to a counter 35 by opening the circuit at intervals of time at which the output is applied, and the clock signal is counted during this time. And, when the transmission receiving part 32 does not receive a reflected signal even if a defined counted value L is exceeded, an abnormality is indicated.

Title: Manufacture of resinoid grindstone
Inventor: SAWAKE KOUICHI
IPC: B24D3/28
Filed: 1983-01-13
Abstract: PURPOSE:To prevent slip and clogging of the grindstone by a method wherein granular filler, employing hydroxy propyl cellulose, insoluble and inflatable with respect to water and having low degree of substitution, as binding and corrupsing agent, is mixed with phenolic resin and abrasive grains to form the grindstone. CONSTITUTION:3-15 parts by weight of hydroxypropyl cellulose, having low degree of substitution, is added to 10pts.wt. of filler and good binding and corrupsing properties may be obtained, further, uniform mixing and molding is permitted. The corrupsing property is caused by the water inflatabiliy of the hydroxypropyl cellulose and is generated by the inflating pressure thereof. The filler improves the performance of the grindstone so as to make the grinding effect of the abrasive grains effective at all times, improves also the economic property of grinding work and helps the emission of heat, generated by the grinding and cutting, from the surface of a metallic work piece.

Abstract: PURPOSE:To prevent occurrence of potential difference due to different breakdown voltage of a protective element, by rectifying an abnormal voltage applied onto a communication line through a rectifying element then absorbing abnormal current through different protective elements according to the polarity of the abnormal voltage. CONSTITUTION:Two diodes 1a, 1b having cathodes connected each other and two other diodes 1c, 1d having anodes connected each other are grounded respectively through Zener diodes 2a, 2b, and the joints A, B between diodes 1a, 1c and 1b, 1d are connected respectively with a communication line 3.

Filed: 1989-01-13
Abstract: PURPOSE:To abate disturbance in controlling an anti-lock brake system by providing bilaterally asymmetrical circular-arc formed guides for dividing a part of a space part into small areas in the inner and outer peripheral directions extendedly at the side face of a blade. CONSTITUTION:Guides 50a, 50b are provided at high pressure generating parts at the time of normal rotation so as to divide space parts 44 into plural small areas A1, B1 in the radial direction. Accordingly, the flow (a) of a highly viscous fluid at the time of normal rotation flows within the small area A1, so that vortex is not easily generated, generating pressure is doubled, and the pressing force of an operating piston is heightened. At the reverse rotating time of a blade 42, the pressure of large areas A, B becomes high, but the flow (b) of the highly viscous fluid in the large areas A, B flows largely, so that vortex is easily generated, and pressure generation thereby becomes lower in reverse rotation than in normal rotation. Pressure generating characteristic of becoming high or low according to the normal or reverse differential rotation can be thus obtained.
