Title: Manufacture of semiconductor element
Inventor: SHIMOKAWA MASAAKI
IPC: H01L21/31
Filed: 1988-02-02
Abstract: PURPOSE:To prevent the function of a final protective film from decreasing at a sidewall due to brittleness by forming the sidewall made of a plasma silicon nitride film, P-SiN film, on the sidewall of the step of a base, and then forming a plasma silicon nitric oxide film, P-SiON film, on the whole surface. CONSTITUTION:A plasma silicon nitride film 13 is formed on the whole surface of a base having a step. The whole film 13 is anisotropically etched, the sidewall 13a of the film 13 is formed on the sidewall of the step of the base, and all the film 13 is removed from the other. A plasma silicon nitric oxide film 14 is formed as a final protective film on the whole face of the base. Thus, the decrease in the function as the protective film due to an brittleness is prevented by the sidewall 13a.

IPC: H01J43/12
Filed: 1978-02-28
Abstract: PURPOSE: To establish high secondary electron emission rate, by constituting the electrodes with the secondary electron emission electrode forming perforated insulation thin film layer on the conductive substrate and the secondary electron collection electrode of positive potential, and improving the secondary electron emission performance due to gas ion injection.  
     CONSTITUTION: The perforated insulation thin film layer 3 is formed on the substrate 2, and the secondary electrons produced with the secondary electron emission electrode 1 are collected at the collective electrode 4 of mesh shape. The DC voltage V c  to keep the collection electrode 4 positive to the electrode 1 is fed. With this constitution, when ion flow 5 is incident on the electrode, it is accelerated with the DC voltage V c  collides with the surface of the electrode 1, emitting secondary electrons from the surface and they are collected with the electrode 4. With this construction, since the thin layer 3 is almost the same potential as the electrode 4, the secondary electrons produced from the deep part emit from the surface while repeating the multiplication by collision inside it along the potential gradient.

Filed: 1979-02-26
Abstract: PURPOSE:To heighten the control response frequency of a liquid jet recording method adapted for small-size high speed recording by passing ion flow from a bias shield electrode layer side through an aperture to collide it with flying droplets to charge and deflect the droplets. CONSTITUTION:A liquid jet recorder has a deflecting electrode 3 at one side of and a laminate 8 of a control electrode layer 4, an insulating layer 5 and a bias shield electrode layer 6 stacked sequentially from the flying passage 2 of droplets 1 at the other side of the flying passage 2 and perforated with an aperture 7 therethrough in parallel with the flying passage 2.

Abstract: PROBLEM TO BE SOLVED: To minimize the dispersion in the quantities of braking of each vehicle unit by changing a power regenerative brake current in each control unit, based on the difference between the integrated value of a regenerated current obtained in every control unit and the average value of the integrated vales of regenerated currents.

Abstract: PURPOSE:To obtain a space with high magnetic flux density by opposing magnetic poles magnetized the same of a couple of cylindrical or columnar magnets and driving a diaphragm by a voice coil interlinked with the magnetic flux vertical to the axial direction of the magnets generating from the opposing part. CONSTITUTION:A couple of the cylindrical magnets 1, 2 are arranged so that the same magnetic poles (e.g., the N poles) are opposed via a disc spacer respectively. In this state, the magnets 1, 2 are fixed to a frame 5 by a fixing screw 4.

Abstract: PURPOSE:To enable a head to be positioned in a short time to a non-recorded position by positioning a head after shifting it a prescribed quantity in a prescribed direction from a position whereat the presence of the record is firstly detected by a reverse movement. CONSTITUTION:A magnetic disk 2 is rotated by a motor control circuit 89 so that the disk is not injured by a system controller 91 during the movement of the head 5. Simultaneously, a step motor drive circuit 87 is controlled so that the head 5 is moved in the direction of X towards the central position of the disk until it is stopped at a last number track position. Then the head 5 is moved in the direction opposite to the direction X while a changeover switch 86 is switched to a contact C to start the operation of a record presence/ absence detector 85. By responding to the first output H responsive to the record presence from the circuit 85, the controller 91 controls a circuit 97 to stop the head 5, then to move the head by one track in the X direction for positioning the head. Hence, the head can be positioned to a non-recorded track surely in a short time irrespective of the erased track, etc.
