Abstract: PURPOSE:To provide a simple and easy manufacturing method of a high- precision LDD structure. CONSTITUTION:By an isotropic etching operation by making use of a photoresist 5 as an etching mask, a polycrystal silicon film is etched, and a gate electrode 6 is formed. At this time, the polycrystal silicon film at the end part of the photoresist 5 is side-etched positively. Then, by making use of the photoresist 5 as can ion implantation mask, phosphorus ions are implanted into a polycrystal silicon film 2 via a gate oxide film 3, and heavily doped regions 7a, 7b are formed. In succession, by making use of the photoresist 5 as the ion implantation mask, the phosphorus ions are implanted obliquely into the polycrystal silicon film 2 via the gate oxide film 3, and a lightly doped region 8a is formed. As a result, in the polycrystal silicon film 2, the lightly doped region 8a is formed, in a self-aligned manner, in a region excluding a part directly under the gate electrode 6 at the inner side than the heavily doped region 7a.

Title: Plasma treating apparatus
Inventor: SAKASHITA TAKESHI
IPC: H01L21/302
Filed: 1979-02-20
Abstract: PURPOSE: To reduce treatment irregularity by carrying out plasma treatment between substrate plates or within a substrate plate uniformly by a mechanism wherein, in case of imparting reciprocal movement to an axial direction of a vacuum container and rotary movement around an axis to a substrate plate putting table, at  least the former movement is imparted.  
     CONSTITUTION: A support 2 for supporting a substrate plate 1 is put on a substrate plate putting table 24 and, after a top cover 11 is put on a vacuum container 10 to close and evacuated from an exhaust port 20, a high purity gas is introduced from a gas introducing port 19. When gas pressure in a container 10 becomes constant, a rotary shaft 21 is rotated at a constant angular speed. Thereby, the movement of a guide pin 25 is initiated on a guide groove 22 and a container 10 is reciprocally moved to an axial direction because the rotation of a putting table 24 attached by a pin 25 is prevented by a stopper 29. Subsequently, high frequency electric power is applied to a high frequency electrode 18 by operating a high frequency oscillator 17 to generate plasma and a substrate plate 1 is subjected to etching treatment by plasma for a predetermined period.

Abstract: PROBLEM TO BE SOLVED: To provide specific resistance necessary to be hated in a normal temperature area, reduce dispersion of the specific resistance to a temperature change, and provide excellent heat resistance by forming a ceramic heating element of composite ceramics of a perovskite type oxide and magnesia, and setting the weight ratio to a specific range. SOLUTION: A perovskite type oxide and magnesia expressed by a formula [(La1-x Ax ) (B)O3 ] are formed of composite ceramic on which the weight ration is set to 1:9 to 7:3. In the formula, (0.05<=x<1) is realized, and A is Mg, Ca, Sr, Ba or the like, and B is Mn and Cr. The composite ceramic can be excellently heated as a heating element since specific resistance can be set to 10 to 10Ω.cm in a normal temperature area, and dispersion of the specific resistance to a temperature change by heating can be reduced, and heat resistance is improved. The specific resistance of the composite ceramic can also be easily adjusted by properly adjusting the content of magnesia being an insulating material.

Title: Electromagnetic display device
Inventor: JIYON BURAUN
IPC: G09F9/37
Filed: 1989-01-31
Abstract: PURPOSE: To obtain a more economical display device by using a reversible stator core of a single high-residual magnetism, which is provided with an anterior free end part positioned on a line being parallel in a visual field direc tion extending from a rotary axis to a rear part. CONSTITUTION: The residual fluxes of the core 24 having an S-polarity 28 keep a rotor 22 at one of halt positions as against a stopping material 20 by a deenergized coil 26 and the side surface A of the rotor is displayed in a visual field direction. When the coil 26 is energized in order to reverse the polarities of the core 24 and a core end part 28, a reverse polarity rotates the rotor 22 under the control of a magnet 38 and executes stopping as against the other stopping materials 20. When the core 24 is temporarily changed-over, the residual fluxes of the core 24 holds the rotor 22 at the position unless the coil 25 is continuously energized. When it is desired that the position of the rotor 22 is reversed again, the direction of the coil 26 is corrected by a pulse in order to reverse the polarity of the core 24.  Thus, easy magnetic driving is obtained and the rotor is driven by the single core between the limited positions.

Abstract: PURPOSE:To detect a micro defect present in the vicinity of the surface of a steel material with high sensitivity by setting the water distance of a probe of a specific frequency and a specific focal length so that ultrasonic beams are converged in a specific range including the surface of the material. CONSTITUTION:The water distance (distance from a probe to the surface of a material to be inspected) for a probe having a frequency of not smaller than 15MHz and not larger than 50MHz and a focal length of not smaller than 12.7mm and not larger than 38.1mm is set so that ultrasonic beams are converged in the range of 2mm below the surface of water including the surface of the material. When this kinds of point convergent ultrasonic waves is brought into the material from the surface perpendicularly within + or -5 degrees, a multi- reflecting echo generated from a micro defect within 2mm from the surface can be detected. Therefore, a defect below the surface can be detected by utilizing the multi-reflecting echo. If a wide-band probe having a narrow pulse width is used, the insensitivity band of the surface echo can be reduced more.
