Title: Impact type printing apparatus
Inventor: ITOU JIROU
IPC: B41J9/38
Filed: 1979-04-16
Abstract: PURPOSE: To accomplish a smaller size and a lower power consumption with the guaranteed given clearness of priting by means of an intermediate level provided between the transmission level to be directly attracted to the electromagnet and the impact hammer.  
     CONSTITUTION: An intermediate lever 34 is provided between the transmission lever and the impact hammer 26. The attraction of the electromanget 23 is transmitted to the impact hammer 26 from the transmission lever 24 via the intermediate lever 34 so that the hammer strikes the type 27 and the ink ribon 28 to print. In this case, the relation between the average clearance length δ 1  between the magnetic material piece 25 and the electromagnet, the stroke Δx 1  of the impact hammer and a 1 , b 2 , a 1 ' and b 1 ' is given by the equation I or II, ensuring the improvement in the lever ratio to (b 1 /a 1 ) (b 2 "/a 1 ') from (b 1 /a 1 ). As a result, if the stroke Δx 1  of the impact hammer is the same as the conventional one, the clearance length δ 1  can be reduced as the lever ratio increases, ensuring the efficient application of the electromagnet along with a less size. The current flowing through the electromagnetic coil is minimized thereby lowering the heat generated.

Title: Plasma device
Inventor: MANABE YOSHIO
IPC: C23F4/00
Filed: 1986-03-04
Abstract: PURPOSE:To form a film having uniform and good quality with simple constitution by disposing a cylindrical substrate in a plasma chamber to which a microwave and magnetic field are impressed and making the intensity distribution of the magnetic field high near the cylindrical substrate and low in the position apart therefrom in the outside circumferential direction. CONSTITUTION:The cylindrical substrate 2 is disposed into the plasma chamber 1 where plasma is induced by the microwave and magnetic field. A gas for CVD is then introduced into said chamber. The above-mentioned magnetic field is impressed in approximately parallel with the substrate 2 by hole pieces 8 disposed on the outside of the plasma chamber 1. The intensity distribution thereof is formed high near the cylindrical substrate 2 and low in the position apart therefrom in the outside circumferential direction. The direct contact of the plasma with the chamber wall is thereby obviated and the ions and free radicals are transported to the cylindrical substrate 2 by which the good-quality film is formed without a rotating mechanism. The intensity of the magnetic field near the cylindrical substrate 2 is adjusted to the intensity at which electron cyclotron resonance arises or above and the plasma chamber 1 is formed to the cylindrical shape coaxial with the cylindrical substrate 2 so that a coaxial or semi-coaxial type microwave resonator is preferably formed by both.
