Filed: 1988-05-06
Abstract: PURPOSE:To obtain a nonlinear optical compd. having great nonlinearity, great absorptivity for ultraviolet rays and visible rays at short wave length side, and high threshold value against breakage due to laser by introducing an acceptive substituent having a specified Hammett's substituent constant into phi, which is a mother skeleton having H or aliphatic substituents R1-R3 in phi-NR1-N=CR2R3. CONSTITUTION:The compd. has a structure expressed by formula I, wherein phiis an aromatic or heteroaromatic ring; A is an acceptive substituent having a Hammett's substituent constant sigma and 0<sigma<0.75; each R1, R2, and R3 is H or an aliphatic substituent. Namely, an acceptive substituent having a Hammett's substituent constant sigma defined by 0<sigma<0.75 and a donative linkage (-NR1-N= CR2R3) are introduced into a pi-electron conjugated system of an aromatic or heteroaromatic ring, thus the superpolarizability of a molecule is increased. The imine linkage (-N=CR2R3) contributes to increase charge transfer and is effective for increasing optical nonlinearity. By this constitution, a compd. having absorptivity for ultraviolet rays and visible rays at the short wavelength side and having also optical nonlinearity by one figure larger than standard conventional compds. is provided.

Title: Powder-filling device
Inventor: MUTO YASUTAMI
IPC: B65B1/32
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To increase filling accuracy, by filling power into a container by means of a powder supply device with a screwlike powder-conveying shaft and, at the same time, measuring the weight of the powder filled in the container, and by controlling the speed of the rotation of the powder-conveying shaft so that it decreases with an increase in the weight of the powder filled into the container. SOLUTION: A container 1 into which powder is to be filled is held on a tray 2, and the powder is filled into the container 1 by a powder supply device 3. The powder supply device 3 has a screwlike powder-conveying shaft 10 which feeds the powder by rotating on a conveying rotation-axis in a storage part 6 and powder passage 7. While the powder is filled into the container 1 by the powder supply device 3, the weight of the powder filled in the container 1 is measured by a load cell 5. In the case, the speed of the rotation of the powder-conveying shaft 10 is controlled so as to decrease with an increase in the weight of the powder filled in the container 1 measured by the load cell 5. This makes it possible to fill only a desired amount of powder into the container 1 without being influenced by a change in the condition of the powder.

IPC: G11B21/02
Filed: 1986-05-15
Abstract: PURPOSE:To surely protect the feeding motor of a pickup arm from a mechanical shock, for example, at a transportation time, etc., by providing a clutch means at the power transmission means of an arm feeding motor. CONSTITUTION:At the transportation time, when a shock is applied on a recording disk reproducing device, torque equivalent to the weight of the whole of a device is generated at the coupled in one body gear 610 of a transmission means 66 from a subchassis 17, and the torque is transmitted to the second gear 65. When the torque from the second gear 65 becomes a force by which a cone projection 601 slips out of a coaxial hole string 602 at the first gear 64 whose rotation is blocked by a worm 60, the first gear 64 ascends the slope of the cone projection 601 against the force of a coil spring 618, and the cone projection 601 moves changing the coaxial hole string 602 to be fitted one after another. By the above operation, the first gear 64 ceases to receive the torque from the second gear 65, and an excessive load is no more applied on an arm feeding motor 61 in an axial direction through the worm 60.
