Abstract: PURPOSE:To facilitate discharge of polishing scraps and to prevent the occur rence of clogging in an abrasive grain layer by supplying cleaning fluid from the end portion of a forming base material, externally fitting a porous compact to a fluid supply pipe shaft having an exhaust hole on the periphery thereof and boring a discharge hole in a portion of a heat contraction tube where there is no abrasive grain layer. CONSTITUTION:An indefinite number of discharge holes 14 are disposed along exhaust grooves 13a-13f produced in a portion of the surface of a heat contrac tion tube 10 where there is no abrasive grain layer. With the tube 10 adhering to a forming base material 2, when a cleaning fluid is supplied from a supply beak 3a of a fluid supply pipe shaft 3, the fluid is dispersed in a porous impact 5 through an exhaust hole 3b and jetted from a discharge hole 14 to the exhaust grooves 13a-13f. Thus, when a polishing surface 4 of a forming wheel 1 is pressed to a polished surface (f) of a work piece W to be polished, polishing scraps stay in the exhaust grooves 13a-13f, which are removed through the exhaust grooves 13a-13f by a cleaning fluid jetted from the discharge hole 14. Accordingly, clogging is hardly caused by polishing scraps in partial abrasive grain layers 12a-12f and the renewal frequency is decreased.

Title: Solidification time deciding method
Inventor: HONMA REIKO
IPC: G01N11/16
Filed: 1990-03-29
Abstract: PURPOSE:To shorten the measurement time without decreasing the measurement accuracy by using variation in the oscillation frequency of a piezoelectric oscillator as an index of measurement and finding the time when the frequency variation reaches a threshold value when the solidification reaction of a liquid sample is measured. CONSTITUTION:A cell 2 where one side of the crystal oscillator 1 contacts liquid contacts a thermostatic chamber 3 and is connected to an oscillation circuit 4, a frequency counter 5, and a microcomputer 6. The surface of the piezoelectric oscillator connected to the oscillation circuit 4 vibrates finely and when a material contacts the oscillator, its oscillation is affected, so that the oscillation frequency varies. The oscillation frequency decreases gradually as the solidification reaction advances and becomes constant at the end of the solidification. The time up to when the oscillation frequency reaches a certain constant value (threshold value) is found to decide the solidification and the solidification time is decided at the time Ta when a point A is reached.

Title: Ignition timing controlling apparatus for internal-combustion engine
Inventor: IWATA TOSHIO
IPC: F02P5/153
Filed: 1982-05-14
Abstract: PURPOSE:To prevent excessive delay of the ignition timing of an internal-combustion engine, by restricting the control quantity in delaying the ignition timing for sporadically caused high knocking in an ignition timing controlling apparatus which executes feedback contrl of knocking. CONSTITUTION:The level of knocking signals applied to an integrator for controlling the ignition timing during one ignition cycle is restricted by a means 6 for restricting the control quantity of delay of the ignition timing. A capacitor 63 is charged by a knocking detector 2 and discharged by a transistor 67 at each ignition cycle. In case that the level of knocking signals during one ignition cycle is high, the charging voltage of the capacitor 63 becomes higher than VR, so that the level of the output signal of a comparator 68 becomes low and an AND-circuit 69 is closed. Therefore, it is avoided that the ignition timing is delayed greatly by a single, high knocking signal. On the other hand, in case that knocking is caused continuously, the ignition timing is delayed by a required quantity.
