Title: Controller for posture of baggage
Inventor: MAEKAWA KIYOSHI
IPC: B65G57/28
Filed: 1983-03-25
Abstract: PURPOSE:To permit efficient loading when box-shaped baggages are loaded in stage form by installing a dimension measuring apparatus on an upstrem-side conveyor and installing a direction changing apparatus on a downstream-side conveyor, among two conveyors which cross at right angles with each other. CONSTITUTION:When a baggage A is transported on a conveyor 1 and reaches the position of a dimension measuring apparatus 3, a rotary encoder 6 starts counting, and sends the result of counting as the data of length into a controller when passage of the baggage is completed. Said controller compares the data with a set data and judges the correctness in direction change, and when changing direction is necessary, a raising and lowering means 11 is positioned at a descent position. Therefore, the baggage A is guided into a guide roller 14 by the synthesized transfer actions of the conveyors 1 and 2, and direction-changed by 90 deg. in the horizontal direction and transported by the conveyor 2. When direction change is unnecessary, the elevation means 11 is operated to project a belt conveyor 8 upwardly from a roller R. After the baggage A is loaded onto the belt conveyor 8, the baggage A is loaded onto the roller R and transferred onto the conveyor 2.

Title: Semiconductor substrate spin coating method and device
IPC: B05D1/40
Filed: 1992-03-10
Abstract: PURPOSE:To stop coating solution from flying off from the peripheral part of a substrate so as not to adhere to the edge face or the rear of the substrate by a method wherein the substrate is rotated at a high speed as a contact is kept coming into contact with the edge face of the substrate. CONSTITUTION:An applicator nozzle 4 is positioned at the center of a substrate 1, and a prescribed amount of coating solution 5 such as adhesive wax is made to drip from the nozzle 4. At this point, a contact 7 such a Teflon thread is kept on standby by the side of the substrate 1. As the contact 7 is kept in contact with the edge face of the substrate 1, a rotary table 7 is rotated at a high speed in the direction indicated by arrow F through a spindle shaft 6. At this point, coating solution hardly adheres to the edge face or the rear of the substrate 1. By this setup, coating solution flying off from the peripheral part of a substrate can be prevented from adhering to the rear or the edge face of the substrate, so that the substrate can be improved in both quality and yield.

Title: Control device for internal combustion engine
Inventor: NOZAWA MASAE
IPC: F02M25/07
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To early activate catalytic converters when an internal combustion engine is in a cold state. SOLUTION: A CPU 31 in an ECU 30 operates VVT mechanisms 23, 24 when an engine 1 is in a cold state, and controls the amount of overlap of valve-openings of an intake valve 11 and an exhaust valve 12 to an extent of 30 deg.CA. In this case, internal EGR is actively performed to slow down the burning speed of fuel in a cylinder, and unburnt fuel which is not burnt in the cylinder, is discharged in an exhaust pipe 3 and then self-ignites to be burnt (after-burning). By positively allowing the unburnt fuel to after-burn in the exhaust pipe 3, the temperature of exhaust gas is maintained at high temperatures, and thus early activation of catalytic converters 13, 14 in cold state is accelerated.  Further, when the engine 1 is in a cold state, the CPU 31 performs control of angle of lag of the ignition timing, control of air-fuel ratio in lean state of a mixture, and control of spark advance of the exhaust valve 12. By combining these control operations and performing these control operations the effect of an increase in the temperature of exhaust gas by after- burning can be more positively realized.

Title: Optical pickup device
Inventor: YAMANAKA HARUYOSHI
IPC: H01S5/00
Filed: 1988-03-08
Abstract: PURPOSE:To reduce the slippage of a focusing point at writing and reading times and to prevent the generation of a signal error by combining the lens system having a color aberration and semiconductor laser having an astigmatic difference. CONSTITUTION:A semiconductor laser is reduced at its astigmatic difference when its optical output is increased and, on the other hand, the wavelength is moved to a long wave length side and the focusing point is slided together by the color aberration of a lens system. For instance, when the optical output of the writing and reading laser 1 to an optical disk 4 is taken in 15mW and 2.5mW, a 2-3nm wavelength is moved by switching and the slippage of the focusing point by color aberration becomes in 2-3mum. The astigmatic difference is reduced in 2-3mum in case of the astigmatic difference of 5mum being in 15mW in case of <=5mW optical output. The slippage of the focusing point by the movement of an oscillating wavelength is combined so as to absorb it by the fluctuation of the astigmatic difference. The slippage of the focusing point at writing and reading times is thus reduced and the signal error can be eliminated.
