    • A method for producing .alpha.-(p-isobutylphenyl)propionic acid or its alkyl esters which is characterized in that starting materials are inexpensive, processes are easy to be done and products are highly pure. The method comprises the steps of (I): catalytically cracking 1,1-bis(p-isobutylphenyl)ethane at temperatures in the range of 200.degree. to 650.degree. C. in the presence of a protonic acid catalyst and/or a solid acid catalyst to produce isobutylbenzene and p-isobutylstyrene; and (II): reacting said p-isobutylstyrene with carbon monoxide and water or alcohol at temperatures in the range of 40.degree. to 150.degree. C. in the presence of a metal complex carbonylation catalyst to produce .alpha.-(p-isobutylphenyl)propionic acid or its alkyl ester; or (III): reacting said p-isobutylstyrene with carbon monoxide and hydrogen at temperatures in the range of 40.degree. to 150.degree. C. in the presence of a metal complex carbonylation catalyst to produce .alpha.-(p-isobutylphenyl)propionaldehyde and then oxidizing said .alpha.-(p-isobutylphenyl)propionaldehyde to produce .alpha.-(p-isobutylphenyl)propionic acid. The recovered isobutylene is recycled to produce 1,1-bis(p-isobutylphenyl)ethane by reaction with acetaldehyde in the presence of sulfuric acid.

    • Carbon fibers are produced by continuously heat-treating acrylonitrile fibers up to the crystal collapse starting temperature of said fibers while maintaining said fibers under a fixed length or tension in an oxidizing atmosphere, then sufficiently thermally stabilizing fibers by further subsequently continuously heat-treating them in a temperature range gradually elevated up to a fixed temperature in a range of from a temperature about 20.degree. C lower than the deterioration starting temperature of said fibers to a temperature about 20.degree. C higher than said deterioration starting temperature in an oxidizing atmosphere. The thus sufficiently thermally stabilized fibers are treated with a reducing liquid and subsequently carbonized or graphitized in a non-oxidizing atmosphere or under a vacuum.

    • The objective of this invention is to provide a boost circuit that reduces power consumption and prevents malfunctioning when the input voltage becomes greater than a target voltage for the output voltage. Control circuit module 5 sets both control signals HCNT2 and LCNT2 to low level “L” when the conditions “output voltage VBoost is higher than voltage OVREF” and “voltage (VIN+VOFFSET) is higher than output voltage VBoost” are satisfied. With this, in boost circuit module 7, switch SWH will be off and switch SWL will be on to forcibly switch to mode B. In mode B, because switch SWH is on, output voltage VBoost will be near input voltage VIN, and the power consumption can be reduced.
    • 本发明的目的是提供一种升压电路,其在输入电压变得大于输出电压的目标电压时降低功耗并防止故障。 当条件“输出电压VBoost高于电压OVREF”和“电压(VIN + VOFFSET)高于输出电压VBoost”时,控制电路模块5将控制信号HCNT2和LCNT2设置为低电平“L”。 因此,在升压电路模块7中,开关SWH将断开,开关SWL将被强制切换到模式B.在模式B中,由于开关SWH导通,因此输出电压VBoost将接近输入电压VIN,功率 消费可以减少。
