Title: Control method of inverter for driving induction machine
Inventor: KIMURA FUMITAKA
IPC: H02P25/04
Filed: 1985-12-10
Abstract: PURPOSE:To prevent the generation of an unstable phenomenon, and to improve operating efficiency by computing a correction value of the basis of the quantity of a state in an induction-machine drive system and executing phase modulation to a sine wave as the reference of an inverter control circuit. CONSTITUTION:Input currents to an inverter circuit 5 are detected by a detecting circuit 8, and a correction value phi(t) is computed by an arithmetic circuit 9 on the basis of a current value detected by the detecting circuit 8. An unstable-phenomenon inhibiting-function interrupting section 20 turns a control function ON-OFF in response to the quantity of a state detected by the detecting means. Accordingly, the state in which the correction value phi(t) is added to and subtracted from a theta signal from a theta generator 12 is brought by the unstable-phenomenon inhibiting-function interrupting section 20 and synchronous type operation is conducted under a normal stable-operation state, thus improving operating efficiency as compared to the case of the unnecessary inhibition of an unstable phenomenon.

Title: Perfume modifier which imparts sedative effect
Inventor: OKAZAKI YOSHIRO
IPC: A61K8/00
Filed: 1992-09-25
Abstract: PURPOSE:To develop perfume compositions of various types and fancy, with which a sufficient sedative effect is imparted by using 1,3-dimethoxy-5- methylbenzene as the perfume modifier. CONSTITUTION:A perfume composition containing 0.01-30wt.% 1,3-dimethoxy-5- methylbenzene as a perfume modifier which can impart a sedative effect is provided. This composition may be optionally combined with auxiliary components to give a perfume fluid, a cologne, a skin care, a body rinse, an aromatic agent, a deodorant, a bath or the like. The amount of 1,3-dimethoxy-5- methylbenzene added to the perfume composition may be suitably determined according to the object of use, etc. When the amount of the perfume modifier used is 0.01wt.% or above, the perfume composition can show a sedative effect. Even when the modifier is contained in an amount of above 30wt.%, it cannot show a marked sedative effect. Therefore it is not desirable to add this modifier in an amount larger than that in consideration of the balance among the perfumes.
