Abstract: PURPOSE:To provide an exhaust particulate processing unit that is able to reduce a quantity of exhaust flow coming in a filter so sufficiently for an amount necessary for regeneration and regenerating the filter efficiently in utilizing the restoration of ventilation resistance effectively with the regeneration of each filter and simultaneously to check a melting loss and a thermal crack or the like. CONSTITUTION:Two cylindrical filters 11 and 12 and a small filter being small in ventilation resistance and capacity but high in collecting efficiency both are installed in a first vessel 10 in a parallel manner, and likewise two other filters 21 and 22 of the same technical data are parallelly installed in a second vessel 20. At the time of filter regeneration, first of all, the small filter 14 is regenerated, restoring the ventilation resistance in this small filter 14, and in time of regenerating the filter 11 to be done successively, a quantity of exhaust flow coming in this filter 11 is sharply reduced. Subsequently, the filter 12 is regenerated, and the filters 21, 22 in the second vessel are regenerated in order. With this constitution, in comparison with such a case that the small filter 14 is omitted and only these filters 11, 12 and 21, 22 are regenerated in order, the exhaust flow coming into each filter during regeneration is reducible in quantity, so that power consumption in an electric heater is also reducible.

Sputter etching of CCl4 gas is used for that purpose. After that, the part where the polysilicon film 5A remains is subjected to isotropic etching using the same etching mask 11 to form a gate electrode 5 and the thickness of about 1/3 (about 1,000Angstrom ) the total thickness is removed. For this isotropic etching, plasma etching of C2ClF5 gas is used.

Title: Optical attenuator and its manufacture
Inventor: YAMAMOTO HIRONORI
IPC: G02B6/26
Filed: 1987-08-21
Abstract: PURPOSE:To reduce the cost and size of the optical attenuator by removing part of the coating of an optical fiber and exposing the element wire consisting of the core and clad, heating the element wire part up to temperature close to its softening point while applying external force and thus forming an optical attenuation part. CONSTITUTION:Part of the coating of the optical fiber 1 is removed to expose element wire, the fiber 1 is fixed by a clamper 11 with the element wire part 1a opposite a burner 10, and one end of the fiber 1 is connected to a light source 14 while the other is connected to a photodetection unit 15. When the burner 10 heats the element wire part 1a to temperature close to its softening point, the element wire enters a softening start and when external force such as tensile force and swinging force is made to operate at this time, a fine crack is generated over the entire area of the heated part, so that the crack generates loss of light. The total quantity of the crack, i.e. an attenuation factor is controlled with the heating time and external force and the optical attenuation part 1b with a desired attenuation factor is obtained. Consequently, the need for adjusting operation is eliminated without requiring any optical element and the inexpensive, small-sized optical attenuator is obtained.
