摘要： This invention relates to a process for press-forming workpieces and a bolster apparatus for the same. The process employs a first bolster apparatus comprising a die holding portion and a transfer, and a second bolster apparatus comprising a die holding portion and a transfer. The process comprises the steps performed sequentially: an exchanging step of removing the first bolster apparatus from a bolster mounting portion of a pressing apparatus and mounting the second bolster apparatus to a bolster mounting portion of the pressing apparatus, thereby exchanging the first bolster apparatus with the second bolster apparatus; and a press-forming step of press-forming second workpieces with the second dies held in the second bolster apparatus by operating the pressing apparatus. The process and the bolster apparatus improve the productivity, and are advantageous when producing various types of products by the small lot, because the transfer can be exchanged simultaneously with the exchange of the bolster apparatuses. In addition, the bolster apparatus has done away with the base for the transfer, because the transfer is incorporated in the bolster apparatus.

摘要： A device for detecting properties of electrically conductive water-soluble oil used in hydraulic pressure-operated devices. The water-soluble oil property detection device is characterized in that it comprises a pair of electrodes placed in a water-soluble oil, a capacitor which is connected in series with the electrodes and which forms a filter circuit with the resistance of the water-soluble oil between the electrodes, a high-frequency power source which has a high-frequency oscillator circuit and a power amplifier and which is connected to both ends of the capacitor and electrodes, and AC-DC converter circuit which detects a high-frequency voltage value occurring at both ends of said capacitor or the resistance between the electrodes and converts the value to a direct current voltage signal, and an indicator part which indicates the output of the converter circuit in correspondence to water-soluble oil property changes.
