Title: Hollow cylindrical honeycomb body and combustion device
Inventor: KAWASAKI YOSHITAKA
IPC: B01D53/94
Filed: 1988-12-15
Abstract: PURPOSE:To facilitate and complete the passage of gas and to improve gas purifying performance and reaction performance by a method wherein a plurality of plateform honeycomb bodies each having a number of communication holes are arranged to form a hollow cylindrical shape. CONSTITUTION:When gas is introduced through a lower opening, after it gradually flows along a flow passage and is collided with a cover body 5, it is dispersed in the direction of surroundings. The gas flows through communicating holes 2 to the outside of a hollow cylindrical honeycomb body 3. During the passage of it, floating particles are present in gas, the particles are captured by means of the inner surface of a honeycomb plate 1, and purified gas flows to the outside. In case of introducing gas having a high temperature, during passing through the communicating holes 2, heat exchange is effected therein, and heat possessed by the gas is moved to the honeycomb plate 1 to heat the honeycomb plate. Recovered heat is emitted to surroundings. Thus, since a gas flow passage is dispersed in a direction extending approximately at right angles with that of its original flow, there is no need for a wide space on the extension line of a gas generating source. Besides, since a high surface area can be ensured in a low volume, even in the case of a filter action or heat recovery, a device is compacted and efficiency is improved.

Filed: 1989-12-08
Abstract: PURPOSE:To perform cutting and good/bad discrimination of a glass original disk while checking the focus state by providing an observing means which observes an actuator driving current or voltage. CONSTITUTION:The change of the drive current is monitored by a digital oscilloscope 12. That is, both end voltages of a resistance R1 are inputted to the oscilloscope 12 through a buffer amplifier to forcibly monitor the drive current because the drive current flowing to a voice coil C flows to this resistance R1.
