Abstract: A method and apparatus for successively conveying substrates between a plurality of processing units, the processing units processing the substrates as required where, when one of the plurality of processing units raises an alarm to inform the user of the occurrence of some abnormality, the processing and conveyance of the substrates located on the transport path in and after either an alarm-raising processing unit or a predetermined skip-mode subject unit are completed; however the conveyance is suspended for the substrates located on the transport path before either the alarm-raising processing unit or the predetermined skip-mode subject unit.

Abstract: Transport robot circulates in a predetermined order among a plurality of substrate processing parts while holds substrates, thereby to perform circulating transportation of the substrates. Controller calculates a minimum wait cycle which corresponds to the number of circulating transportation during time from first circulating of a first substrate to first circulating of a second substrate under the condition that interference between the first and second substrates is prohibited. When the minimum wait cycle is shorter than a standard wait cycle which corresponds to the number of circulating transportation for processing of the first substrate, starting of the circulating transportation of the second substrate is delayed in the range of the minimum wait cycle to a standard wait cycle. Hence, the processing of the second substrate can be started without waiting for completion of the processing of the first substrate, resulting in that through put is improved.

Abstract: Substrates of a precedent lot are transported among first processing parts while being processed by the first processing parts. The circulating transportation for the precedent lot is interrupted after starting of the circulating transportation of the first substrate of the precedent lot before starting of the circulating transportation of the last substrate of the precedent lot. Thereafter, a substrate of a subsequent lot is transported among second processing parts while being processed by the second processing parts. Hence, processing of the substrates of the precedent and subsequent lots are concurrently processed, resulting in improving a through put.

Abstract: The present invention provides a membranous-vibration sound absorbing material which can achieve not only good sound absorbing characteristics, workability and strength but also transparency. The membranous-vibration sound absorbing material can also achieve dust-proof and dust-free properties when necessary and can be suitably used for application in clean rooms and the like.

The aluminum base metal foil (or thin resin film) has ruptures, which vibrate in the process of sound absorption to permit the sound absorbing material to exhibit excellent sound-absorbing characteristics over a broad frequency range. The improved sound absorbing material can be produced by a process which comprises the steps of preparing a laminate comprising the members described above and pressing the laminate so that the individual members are compressed together while forming ruptures in a regular pattern in the aluminum base metal foil (or thin resin film).

Abstract: A process for preparing a porous metal plate is disclosed which is adapted to use short metal fiber to prepare the plate. The process is capable of providing a porous metal plate which has increased bending strength and porosity, of which the porosity and thickness are controlled as desired and which has a wide and lengthy shape. The so-formed porous metal plate is capable of being extensively utilized, for example, not only as a filter and a sound absorption material but for a fuel cell, a catalyst and the like. It is formed by applying adhesive onto a surface of a substrate, and embedding short metal fibers in the adhesive. The composite thus formed is then pressed, to push over the short metal fibers, and the composite is then sintered. The substrate is a material which is capable of being burned out, or is a metal net, or is a release paper, so that the final plate will be porous throughout.
