    摘要: A method for producing an aromatic carbonyl compound represented by the formula (B)-1 or (B)-2: ##STR1## comprising decomposing a hydroperoxide represented by the formula (A)-1 or (A)-2: ##STR2## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are defined in the specification, in an inert gas atmosphere in the presence of an aqueous layer containing an iron salt, a copper salt and an acid is disclosed. Novel m-(2-hydroxy-2-propyl)acetophenone and m-isopropenylacetophenone which are useful as an intermediate for the preparation of medicines are also disclosed. A method for producing m-isopropenylacetophenone comprising dehydrating m-(2-hydroxy-2-propyl)acetophenone in the presence of an acid catalyst is further disclosed.

    摘要: RFID tags are attached to tools of a preform head, a bonding head, and a push-up unit, and information related to each tool such as a dimension of a processing-target die is stored into the RFID tags. When a tool is mounted, an operator inputs manufacturing conditions related to the tool. When information related to the tool read from the RFID tag by an RFID reader/writer and the manufacturing conditions related to the tool do not match each other, a message about wrong mounting of the tool is displayed on a monitor. Further, an operation history of the tool is written into the RFID tag by the RFID reader/writer when the production is completed. The operation history is read when the next production is started, and if the values of the operation history exceed predetermined numbers of times, a message is displayed on the monitor.

    摘要: The present invention provides a manufacturing method of a semiconductor device which can speedily peel extremely thin chips which are laminated to an adhesive tape without generating cracks or chippings. A head of a vibrator is brought into contact with a back surface of an adhesive tape to which a plurality of semiconductor chips obtained by dividing a semiconductor wafer are laminated. By applying longitudinal vibrations having a frequency of 1 kHz to 100 kHz and an amplitude of 1 μm to 50 μm, the chip is peeled from the adhesive tape. In applying the longitudinal vibrations to the adhesive tape, a tension in a horizontal direction is applied to the adhesive tape.
