Title: Coating method
Inventor: MATSUDA HIROMU
IPC: B41M5/26
Filed: 1987-06-26
Abstract: PURPOSE:To orient a surfactant to the surface of a coating liquid to a saturation value and enable stable and sufficient display of the function of the surfactant with a small addition quantity, by a method wherein the period of time required for passage from a coating part to a drying part is set to be not shorter than the period of time required for the surfactant to be oriented to the surface of the coating liquid in a coating environment ranging from the coating part to the drying part. CONSTITUTION:The period of time required for passage from a coating part to a drying part is set to be not shorter than the period of time required for a surfactant to migrate from a liquid to a gas-liquid surface and reach a equilibrium state. During the passage from the coating part to the drying part, the surfactant is oriented to the surface of the coating liquid to a saturation value, and it is fixed by drying in the oriented state, whereby the function thereof is sufficiently displayed. The period of time required for the function of the surfactant to be stably developed is made to be orientation time. Most of commercial silicone or fluoro surfactants have a high mol.wt., and particularly when the surfactant has a higher mol.wt. or a greater molecular size, the migration of the surfactant in the coating liquid is slower, and the orientation time is longer, resulting in that the desired effect is displayed in the case of practical coating by use of a coater.

Title: Travel controller for battery-powered vehicle
Inventor: SAKANO OSAMU
IPC: B60L9/18
Filed: 1994-07-12
Abstract: PURPOSE:To increase an operating time and to improve the operability at the time of a slow velocity by controlling a drive circuit based on an output signal from a rotation and accelerator sensor, executing a regenerative drive when the number of revolutions of a travel motor is larger than a predetermined value at the time of releasing an accelerator pedal and controlling the slow speed traveling at the time of smaller. CONSTITUTION:A control circuit 7 calculates the vehicle speed based on the number of revolutions of a travel motor 3 detected by a rotation sensor 4. Various drive modes are discriminated based on the rotating direction of the motor 3 detected by the sensor 4, the depressed state of the pedal 5 detected by an accelerator sensor 5a and the set advancing direction detected by a forward/reverse switch 6a. Thus, if the number of revolutions of the motor is a predetermined value or less when the accelerator is turned OFF, the vehicle is traveled at a slow speed, and an operator can travel at a slow speed only by braking without using the accelerator. When it is the predetermined value or more, regenerative operation is conducted to improve the operating time.
