  • Publication number: 20040152894
    Abstract: Processes for producing a compound represented by the formula (1), which includes an acrylic acid derivative and is useful as an agricultural chemical or medicine. One of the processes comprises the step of formulating a compound (3) and converting the OH of the resultant compound (2) into OR″. The first step comprises reacting a formic or orthoformic ester in the presence of a Lewis acid and a base. The second step comprises reacting the compound with R″OH or with R″OH and CH(OR″)3 under acidic conditions or using a phase-transfer catalyst in a two-phase system and regulating the base and the concentration thereof to stereoselectively synthesize the target compound. In another, process, the compound is efficiently produced without isolating the compound. The compound can also be produced without the compound (2).

  • Patent number: 6742349
    Abstract: Data is transmitted to a main control device via sensing means such as temperature sensors, each having a memory means in which the ID code is stored, and via transmitting/receiving means such as switching elements. There is a stand-by period in the operation of the main control device after the main control device issues a command to start a sensing operation until the main control device issues a command to perform a read operation. The main control device receives power through a signal line the voltage of which is kept at a high level during the stand-by period. Thus, an equipment sensing system and an equipment control device which enable reliable and quick sensing, cost reduction, smooth control, and simplified wiring are provided.

The power roller are frictionally engagement with the traction surfaces of the input and output disks and transmit a driving force. At least one of the input disk, the output disk and the power rollers is formed of an alloy steel which contains 0.15 to 2.0% by weight of Mo. The alloy steel is subjected first to carburization or carbonitriding processing executed at a temperature not lower than 1,000° C., and then to hardening and tempering. The alloy steel has a surface carbon content of 0.8 to 1.4%.
