The present invention provides a device for measuring a hard granular object having a measuring vessel, a holder and a shutter which cannot be damaged by a granule caught between them when used to measure a granular object with high hardness and a method for measuring a hard granular object therewith. The present invention also provides a device and a method for removing fine granules from a hard granular object such as spherical adsorptive carbon containing fine granules and measuring the hard granular object. A device 20 for measuring a hard granular object comprises: a measuring vessel 21 having a first face 21d, a second face 21e parallel to the first face 21d, and a space 21a formed between the first face 21d and the second face 21e for receiving a hard granular object supplied from the first face 21d side; a holder 22 located on the side of the first face 21d, having a through hole 22a communicable with the space 21a, and slidable along the first face 21d; a shutter 24 located on the side of the second face 21e, having a through hole 24a communicable with the space 21a, and movable parallel to the second face 21e; and a pressing means 23 for pressing the holder 22 toward the measuring vessel 21.

In a book-making equipment (1) in which laminated sheet papers (10) permit one elevational end side to be bonded on a work table to produce a booklet. The laminated sheet papers (10) are thrown into a hollow space between pressure surfaces (20) with the book-making equipment (1) stood on the work table. The laminated sheet papers (10) thus thrown into the hollow space, permit the one elevational end side or other end side to be trued up with the one elevational end side extended beyond the pressure surfaces (20) by a predetermined length. The laminated sheet papers (10) permit the one elevational end side to be clamped with the clutch pieces 2 stably stood on the work table. This makes it ready to bond the one elevational end side of the laminated sheet papers (10), and eliminating the necessity of the time-consuming labor and the special skill with a good appearance and bonding strength insured in the booklet.

The present invention provides a lubricant for a compression type refrigeration system using ammonia as a refrigerant, which comprises polyether compounds and aromatic amine compounds or phenothiazine compounds, and preferably further comprises alcohol compounds such as polyhydric alcohol partial ether and/or benzotriazole compounds. Further, the present invention provides a working fluid composition comprising the lubricant and an ammonia refrigerant, and a refrigeration system which is filled with the working fluid composition. The lubricant has not only good compatibility with ammonia, but excellent stability and lubricating property, and therefore can suitably used in a compression type refrigeration system using an ammonia refrigerant that does not have the possibility of ozone layer depletion and global warming phenomenon.
