A PID (Packet Identifier) filter circuit includes a FIFO (First-in, First-out) memory. Filtering may be performed irrespective of the length of the PID and irrespective of whether the position of the PID is fixed in the packet. The circuit includes a comparison value table for storing therein comparison values, and a comparator for taking comparison values successively from the comparison value table and for comparing value of the PID in the input packet data with the comparison values on a word by word basis. A FIFO memory stores input packet data. The FIFO memory does not implement a read operation until the input packet data is determined to contain desired data based on its PID. If the input packet data is determined not to contain desired data, any portion of the input packet data already stored in the FIFO is superseded.

A fluid compressor comprising a helical blade type compression mechanism that includes a cylinder, a roller arranged inside the cylinder and a helical blade interposed between the roller and the cylinder. The blade, the roller and the cylinder are formed of materials whose coefficients of thermal expansion satisfy relationships: Blade>Roller>Cylinder. According to this invention, pressure release can be easily performed in the case where the liquid flows back or under a low-temperature condition as at the time of actuation. In addition, the compression performance can be improved under a high-temperature condition during operation.

A laser device dices a substrate by generating a continuous wave-oscillation laser beam 3 that is converged by a lens 4 and focused at a predetermined focus O between the surface of the substrate 1 and a tip of a nozzle of a guide 5. Then, the focus is expanded to result in a laser beam 3a having a beam spot diameter of S at the surface of the substrate 1. A flow of assist gas G.sub.0, G.sub.1, G.sub.2 having a predetermined constant pressure is supplied from a gas intake 6 surrounding the laser beam 3. As the laser beam 3a is defocused, the beam spot diameter S is expanded and its energy distribution is moderated. The gas is blown onto the substrate 1 at constant pressure in order to suppress generation of strains due to thermal deformation.

A refrigerant compressor for using HFC 134a as a refrigerant and a refrigerator oil such as polyether type oil, polyester type oil, or the like which is compatible thereto is disclosed. The refrigerant compressor has a iron type substrate with a compound layer mainly made of iron sulfide on sliding portions such as sliding parts and shaft in the compression mechanism. The sliding parts in the compression mechanism are a cylinder and a rotor and a piston which are moving parts. In a rotary type compressor, the sliding parts are a blade and so forth. The hardness of the compound layer mainly made of the aforementioned iron sulfide is large and thereby effectively preventing metals from being contacted and preventing adhesive abrasion which is the primary cause of the abrasion of the sliding portions. In addition, since the compound is stable in a moist situation, even if it is used along with polyether type oil, polyester type oil, or the like and HFC 134a, corrosion and abrasion due to dissolving of compound layer can be prevented.

A hermetic type refrigerant compressor operates using a refrigerant and a refrigerator oil in which the refrigerant is soluble. The refrigerant compressor includes slidable members adapted to slidably move and a compressing mechanism for compressing the refrigerant with the aid of the slidable members in a hermetic casing. The refrigerant, the refrigerator oil and the slidable members are selected and constructed in the following manner. The refrigerant is a 1,1,1,2-tetrafluoroethane or a 1,1-difluoroethane, the refrigerator oil is at least one kind of refrigerator oil selected from a polyalkylene glycol based oil and a polyester based oil, and at least one of the slidable members has a slidable surface which is prepared such that a surface hardened layer having a Vickers hardness of 400 or more and a thickness of 2 microns or more is formed on a substrate of ferrous metallic material, and subsequently, an iron oxide layer composed of Fe.sub.3 O.sub.4 as a main component and having a thickness of 0.01 micron or more is formed on the surface hardened layer. Each slidable member has surfaces each of which exhibits especially improved abrasion resistance.
