A method and device for irradiating a pulse laser beam having a linear shape and a rectangular shape beam spot onto a non-single crystal semiconductor thin film. The method includes scanning the pulse laser beam so that previous and next beam spots are partially overlapped. The laser beam has a profile which includes: a first beam profile region having a first energy density which is lower than a micro-crystallization threshold value Ea of an amorphous semiconductor for forming a polycrystallization region; a second beam profile region having a second energy density which is not lower than the micro-crystallization threshold value Ea and is lower than a micro-crystallization threshold value Ep of a polycrystalline semiconductor for forming a first micro-polycrystallization region from an amorphous semiconductor region; and a third beam profile region having a third energy density which is not lower than the micro-crystallization threshold value Ep for forming a second micro-polycrystallization region from a polycrystalline semiconductor region.

In a thin film transistor, a first insulating film on a silicon layer formed in an island on a substrate is smaller in thickness than the silicon layer so that the stepped island edges is gentle in slope to facilitate covering the island with a second insulating film. This reduces occurrence of gate leak considerably. Since the peripheral region of the stepped island is smaller in thickness than the central region above the channel, it is possible to minimize occurrence of gate electrode breakage. The silicon layer contains two or more inert gas atoms, and the atoms smaller in mass number (e.g., He) are contained in and near an interface with a silicon active layer while the atoms larger in mass number (e.g., Ar) than those smaller in mass number are contained in and near a second interface with a gate electrode.

The disclosed method involves teaching a robot by moving a robot member and sampling its position at predetermined times. Only position data changed more than a predetermined difference from the last stored position data are recorded as instruction data and the instruction data are played back as position data at predetermined times independent of the time required to move the robot member in the teaching steps.

A control system of an industrial robot includes an operation program read out from a storage medium and deciphered and calculated to obtain data so that a robot machine is controlled on the basis of the data. An external memory has function of a conventional internal memory and it is limited to store one program in, for example, an IC card constituting the storage medium and the IC card is inserted into the external memory to supply the operation program. A plurality of operation programs are previously stored in, for example, a floppy disk device constituting a recording medium of the external memory and a desired program is selected by a keyboard to directly supply it to the controller of the robot to operate the robot.

A method for improving the starting phase of the running of a hydraulic turbine or pump turbine. According to this method, an opening of wicket gates is increased as a function of an increase in r.p.m. of a runner, so that the flow rate of water running into a runner may be maintained constant throughout acceleration and synchronizing process to the rated speed once attained said constant value at an early stage of starting.

To provide a structure and a manufacturing method which can manufacture, at a low cost and with good yield, a liquid crystal display panel having a lenticular lens and a substrate formed in a unified manner. When forming a lenticular lens onto a mother CF substrate by using a wet etching method, substrates are dipped into an etching solution while being raised up in such a manner that the length direction of slit openings of a mask is aligned with a vertical direction and an area having no mask pattern comes on a bottom side. With this, the residuals generated due to glass impurities can be drained towards the lower side along the lenticular lens shape to be discharged to the flat area, which makes it possible to suppress deterioration in the etching processed shape.
