Abstract: PURPOSE:To sufficiently cope with a fluctuation in a linear speed and to perform high-precise control of a tension by determining the reference value of the rotation speed of a delivery drum based on the actual diameter of a delivery drum and a detecting linear speed on the detecting drum side and controlling the rotation speed of the delivery drum through correction of a reference value based on the position of a dancer roll. CONSTITUTION:The actual diameter of a delivery drum 3 is set at an actual diameter setter 17 and a wire rod 7 passes through dancer rolls 6a and 6b, and a winding drum 1 is rotated by a drive device 2. A reference computing part 18 calculates the reference value of the rotation speed of the delivery drum 3 based on an output from a linear speed detector 16 disposed on the winding side and the actual diameter of the delivery drum 3. Meanwhile, the rise of the dancer rolls 6a and 6b is detected by a displacement angle detector 11. An auxiliary computing part 19 corrects a reference value based on the detecting value of a displacement angle detector 11, and the correction value and the reference value are added by means of an adder 20. The adding value is outputted as a speed command value to a drive device 4A to control rotation of the delivery drum 3.

Title: X-ray photoelectron spectral microscope
Inventor: NAKAJIMA KUNIO
IPC: G21K7/00
Filed: 1993-03-15
Abstract: PURPOSE:To simply perform spectral analysis by using a laser plasma X-ray source as an X-ray source. CONSTITUTION:Laser light emitted from a laser 1 is condensed with an optical lens 2 and focused on a target 3. Plasma is produced on the target 3 by means of energy of the laser light and an X-ray is generated therefrom. The X-ray which is spectrally diffracted and condensed with a multilayer film condensing mirror 5 is narrowed down to a small X-ray beam with an X-ray optical element 6, so that a sample is irradiated. The element 6 has good use efficiency of the X-ray and is desired to be an oblique incident reflection type optical element capable of having high resolution. The X-ray is applied to only a part of the sample by means of the X-ray beam and photoelectrons is produced in its minute area. Energy analysis of the produced photoelectrons is performed with a photoelectron spectroscope 7 and they are detected with a photoelectron detector 8. In this state the analysis of an X-ray applied minute area is conducted. As mentioned above, analysis precision can be also heightened in a short measuring time.

IPC: A01D34/47
Filed: 1992-01-30
Abstract: PURPOSE:To improve the grass-discharging effect and the grass-collecting effect of a mower capable of cutting only softer weeds without cutting lawn grasses in a lawn. CONSTITUTION:The rear blade of a mowing plate is designed so as to be composed mainly of inclined parts and the inclined parts are arranged in a line in the central direction. The rear blade is directed upward and continued to the front blade. In a mower for lawn, a grass-discharging unit and a pendulum holder 7 are united into one body so as to perform a grass-collecting and discharging work in both the back and forth directions and a switch mechanism for a guide unit is additionally involved. Further, a large grass-collecting tool 31 is involved and satisfactory collection of grasses is carried out by forced air blown out of a motor chamber, thus making up a remote-controllable automated mower capable of being used in a wide golf course. In addition, in the case of a rotary mower, both the end parts of the mowing plate are fixed to a rotor and the force applied to the mowing plate during the work is reduced. The thickness of the blades can, therefore, made thin.

Title: Field effect transistor
Inventor: GOTO NORIO
IPC: H01L21/338
Filed: 1989-03-07
Abstract: PURPOSE:To control side-gate by forming a level which works as a charged trap at a semi-insulation region which is in contact with the gate metal on the surface of a semi-insulation substrate. CONSTITUTION:In an n-channel electric field effect transistor formed on GaAs semi-insulation substrate 9, a level which works as a hole trap is formed at semi-insulation regions 7 and 8 which are in contact with a gate electrode 3 on the surface of the semi-insulation substrate 9. Then, an n-type conductive layer 4 is formed by ion injection of silicon, a gate electrode 3 is formed by tungsten, and a deep level which becomes a hole trap is formed by ion implantation of chrome. Thus, when the Schottky metal side is biased to a positive potential, a hole trap is charged positively by capturing positive holes injected from a Schottky junction metal, thus increasing potential curvature due to positive charge of the regions 7 and 8. Therefore, implantation of holes is drastically reduced, thus drastically controlling generation of side-gate effect.
