Filed: 1994-10-12
Abstract: PURPOSE: To obtain 3,4-caranediol useful as a repellent for insect pests, by reacting 3-carene with an organic hydroperoxide and then reacting the reaction product with an alkali metal. CONSTITUTION: 3-Carene of formula I is reacted with an organic hydroperoxide (e.g. tert-butyl hydroperoxide) in the presence of a hydrocarbon-soluble molybdenum salt in a solvent (e.g. toluene) at 50-100 deg.C to give 3 caraneepoxide of formula II. Then the compound of formula II is reacted with an alkali metal hydroxide or an alkali metal carbonate under 5-15kg/cm<2> in hydrous ethanol at 100-200 deg.C to give 3,4-caranediol of formula III. The hydrocarbon-soluble molybdenum salt is obtained by heating ammonium molybdate with a 4-30C hydrocarboncarboxylic acid in the presence of an organic amine under heating.

Title: Switchback running control device for industrial vehicle with automatic transmission
Inventor: FUJITA KATSUHISA
IPC: B60W10/11
Filed: 1988-09-30
Abstract: PURPOSE:To have stable switchback running control by gear shifting an automatic transmission by a forward/backward lever into a specified condition when judgement is such that the running speed has attained the specified low speed. CONSTITUTION:During switchback running, brakes are applied simultaneously with changing-over of a forward/backward lever 20 to cause a fork lift to be braked, so that the running speed attains the low speed immediately. When judging from signal given by a car speed sensor 15 that the running speed has attained the low speed, a CPU 41 changes over an automatic transmission into backward gearing position, a control signal is given to a forward/backward changeover solenoid control valve 30 to make drive control of a forward/ backward changeover actuator. This provides stable gear shift into the backward position without generating gear sound or vibration. Because a dry type single disc clutch (e) once disengaged is re-engaged upon changing-over of the gearing into the backward position, a control signal is emitted to a clutch controlling solenoid control valve 28. This provides stable control of switchback running.
