An optical glass comprising in mass %: The optical glass should preferably contain 0.1-5% WO, 3.6-15% MgO, 0.1-5% LiO+NaO+KO, 0&#x2014;less than 0.5% and SbO+AsOwith the mass ratio of ZnO/BaO being 0.12&#x2014;less than 0.50. The optical glass should preferably have refractive index (nd) within a range from 1.54 to 1.65 and Abbe number (&#x3bd;d) within a range exceeding 57 up to 69 and liquid phase temperature within a range from 870&#xb0; C. to 930&#xb0; C. There is provided an optical glass having high resistance to devitrification and medium refractive index and low dispersion characteristics which is free of ingredients such as TaOhaving a high cost of raw material and therefore can be manufactured at a relatively low cost of raw materials.

An optical glass comprises, in mass percent, 15&#x2013;35% of PO, 40&#x2013;60% of NbO, 0.5% to less than 15% of NaO and 3% to less than 25% of BaO, has a ratio in mass % of (BaO+NbO)/{(TiO+WO)&#xd7;3+BiO+NbO}&#x3e;1.0; is free of Pb and As; and has a refractive index (nd) within a range from 1.78 to 1.90 and an Abbe number (&#x3bd;d) within a range from 18 to 27.

A gas cushion apparatus with a support member to hold a blank, gas pressure cylinders that push the support member upwards, a hydraulic cylinder whose upper rod is connected to the support member, a pneumo-hydraulic converter for secondary lifting with a piston that partitions the interior into an oil chamber communicating with the oil chamber on the side of the rod of the hydraulic cylinder and a gas chamber, a check valve that allows oil to flow from the oil chamber on the side opposite to the above-mentioned rod to the oil chamber on the side of the aforementioned rod, and a drain port communicating with the oil chamber on the side of the above-mentioned rod of the hydraulic cylinder.

Die cushion apparatus

An optical glass includes SiO ; PbO; B O ; not less than 0.1 mass % of TeO ; and not less than 0.4 mass % of Li O.

An optical glass comprises the following composition in mass percent of: SiO 18-29%; PbO 68-78%; and TeO 0.1-3.5%; wherein the glass has optical constants which are a refractive index (nd) having a range of 1.75 to 1.87 and an Abbe number (&ngr;b) having a range of 21 to 28; and a wavelength of a light transmitted through the glass having a thickness of 10&plusmn;0.1 mm at a transmittance of 80% by including a reflection loss, is not more than 420 nm.

A high-speed network printer apparatus which can be used in common by clients having different communication protocols and which can sort out printing jobs into the order of clients. Printing information is supplied from a client which may be a personal computer or a work station through a connector of the printer apparatus. A LAN interface driver receives the printing information and identifies a communication protocol by which the printing information is transferred. A communication protocol controller receives printing information in accordance with a predetermined protocol. A spooling controller, which is coupled to a storage unit which stores the received printing information, creates a queue for printing jobs. A printer controller reads out from the storage unit the printing information corresponding to a printing job of the highest priority which is designated by the queue, and forms a dot image on the basis of the printing information. A printing mechanism prints the image on paper. A mailbox stores printed paper into a designated bin. A printing job table is provided in the printer apparatus, in which each row is allotted to one printing job which includes a field for storing an emulation program name. A registering unit judges whether or not there is a another printing job having the same emulation program name to expedite the printing process.

Network printer apparatus and LAN network system

Cross bars 18, to which workpiece holders 19 are attached, are provided across a press line L, together with feed beams 14 between which the cross bars are installed and which are suspended from the lift beams 13 and can move freely in the horizontal direction of the press line. A feed and transfer device 52 can move the feed beams freely in the horizontal direction of the press line. A connecting rod 56 connects the feed beams and the rack beam in a freely rotatable manner. A connecting link 60 connects a point in the vicinity of an intermediate portion of the connecting rod to a bracket 58 installed on the rack beam, in a freely rotatable manner. An operating direction changeover mechanism 61 converts the differential movement caused by the curvature of the press transfer motion, produced in the feed beams when the lift beams are raised or lowered, into a horizontal movement in the direction of the press line in synchronism with the raising or lowering of the lift beams.

Apparatus and methods for transferring workpiece in a transfer press

In a system comprising a data processing unit and at least one output device, the data processing unit extracts from output information prepared by an application program media resource information needed in outputting the output information from the output device. The data processing unit reads needed media resource information from media resource storage on the basis of the extracted information, downloads the read media resource information into the output device and then outputs the output information to the output device to initiate an outputting process.
