Abstract: PURPOSE:To achieve automatic stoppage of any kind of screw irrespective of pitch, by bringing a driver rotary system provided movably up and down against a lowering system to low position under normal state. CONSTITUTION:A work is secured below a base 10 secured to a moving system. A moving table 52 for containing a small screw 40 in a holding hole 53 will move from the lower section of small screw feeder 41 to the lower section of a driver rotary system 30 then air is fed through an air supply hose of moving table 52 to push the small screw 40 upward thus to hold a moving tube 34 in a fixed hole 35. Then said table 52 is reset to stop a motor 31 and upon abrupt lowering of driver rotary system 30 by means of a lowering system 20, the small screw 40 will collide against the work to move the movable tube 34 upward thus to position the leading edge section 33 of output shaft at the head of small screw 40. Upon detection of pressure, said motor 31 will start rotation to separate a lowering frame 22 from a stopper ring 25 thus to compress a spring 26 and to tighten the small screw 40 to predetermined position through rotation of said motor 31.

Title: Plasma control method and plasma generator
Inventor: KIMURA YASUKI
IPC: C23C16/50
Filed: 1994-09-09
Abstract: PURPOSE: To independently cause a periodical change and time modulation of plasma density by determining a composition of fed gas and inputted power for production of plasma into a state to make a plasma atmosphere cause a phase change. CONSTITUTION: A microwave generated from a microwave generating part 114 is inputted into a chamber 111 via a waveguide 113. The inputted power is determined at a value in the vicinity causing a phase change. The microwave causes ECR by a plain wave of 875 Gauss and is absorbed. High density plasma is formed in the vicinity of a plane P. Almost simultaneously with the input of the microwave, power is fed from an RF generating part 122 to an RF electrode 121 and etching of multilayer resist is started. At a time point when composition of ethanol exceeds 25%, power efficiency is changed into a low phase state, and when it becomes lower than 25%, the power efficiency is changed into a high phase state. Since the power efficiency is periodically changed in relation to the ethanol composition change, the plasma density is changed with the elapse of time.

Title: Steering control device of fork lift truck
Inventor: UTSUNOMIYA MASAAKI
IPC: B62D7/14
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent a steering wheel from continuously vibrating by setting a distance between a point showing a first threshold value and a point showing a second threshold value to be a deviation considering the maximum twist angle due to a spring constant in the steering angle direction provided in the steering wheel, in an output characteristic curve of the current command value to a steering motor. SOLUTION: In an output characteristic curve, the absolute value of e1 (a first threshold value) is set to be the same value as a twist angle between a tire and the road surface, and a distance between a point P11 (a point showing a second threshold value) and a point P12 (a point showing the first threshold value) is set to be a larger value than the maximum value of a twist angle under the condition such as various road surfaces and live loads. When deviation E becomes smaller than the e1 after a motor angle passes through a steering angle, the shaft of a motor is returned up to a tire angle by the twist torque of the tire, and the motor shaft is stopped between the point P11 and the point P12.  Further, when the deviation E returns between a point Q12 and the point P12, rotation of the motor is stopped between the point Q12 and the point P12, and hence continuous vibration is eliminated.

Abstract: PURPOSE:To acquire a film thickness measuring device of a simple structure and high precision and a reflecting mirror of high reflectivity wherein it is used by measuring a thickness of a thin film which is deposited and formed on an optical fiber end surface for each specific wavelength of a semiconductor laser. CONSTITUTION:An SiO2 thin film is formed on a substrate 5 as a low refractive index dielectric. When the film is formed to become the same as one-fourth of an oscillation wavelength of a semiconductor laser 1, output of a photodiode 11 shows an extreme value. Formation of the SiO2 thin film is discontinued when the extreme value is shown, and then deposit of amorphous Si is started as a high refractive index dielectric to form a thin film thereof. Also in the process, when a formed film thickness is one-fourth of the wavelength, that is, when output of the photodiode 11 shows an extreme value, a deposit source of a thin film formation material is switched. A multilayer film 6 which is formed by laminating a low refraction factor dielectric and a high refractive index dielectric alternately is formed on a substrate 5 in this way. A reflecting mirror having high reflectivity can be thereby formed.
