Title: Electric field curtain device
Inventor: WATANABE TOSHIO
IPC: B03C3/88
Filed: 1983-12-15
Abstract: PURPOSE:To convey charge particles in a specified direction by connecting the ends of the electric field curtain electrodes provided on an insulating support layer so as to parallel with each other to mutually the same phases by resistance electrodes and providing distributing electrodes via a dielectric layer on the resistance electrodes. CONSTITUTION:Resistance electrodes 6, 7 connecting the ends of electric field curtain electrodes 2, 3 are formed of semiconductors and the electrodes 2, 3 are connected by the same resistors r1...rn and r1'...rn'. The DC voltage gradient which is higher on the side impressed with the power source and successively lower toward the ground side is obtd. between the electrodes 2 and 3 by these resistance components r1...rn and r1'...rn'. The electric field generated between the electrodes 2, 3 is thus gradually decreased from the side impressed with the voltage toward the ground side and the charge particles floated and oscillated on a dielectric layer 8 start moving toward the side where the voltage gradient is lower.

Title: Capacitor
Inventor: KATO REI
IPC: H01L27/04
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To prevent a drop of Q value by a resistance to the earth producing in a semiconductor substrate by forming a lower resistance layer than the substrate between the first insulating layer and the substrate in which a first insulation layer, a first conductive layer, a dielectric layer and a second conductive layer are laminated in sequence. SOLUTION: A conductive layer (low resistance layer) 20 which is lower in resistance than a semiconductor substrate 10 is formed between an insulation layer 12 and the semiconductor substrate 10. Thus, a current flows into the conductive layer 20 through the insulation layer 12 from a conductive layer 14, and it hardly flows into the semiconductor substrate 10. An insulation layer made of oxide film or nitride film may be formed between the conductive layer 20 and semiconductor substrate 10. The formation of the conductive layer 20 reduced a resistance to the earth, and the Q value of a MIM capacitor is made large at a port 1. Since the Q value is improved as the resistance to the earth is reduced, the noise index of an amplifier using a MIM capacitor C can be reduced and a ratio of a carrier of an oscillator output to a noise can be improved.

Abstract: PROBLEM TO BE SOLVED: To provide a display device which facilitates the formation of a display area to a larger area, is capable of recording images with a sample recorder, such as a magnetic pen, and makes it possible to obtain bright display images distinct in brightness and darkness. SOLUTION: The one surface of a substrate 1 which allows the transmission of light is provided with a magnetic layer 2 of rare earth iron garnet. The surface of this magnetic layer 2 and the other surface of the substrate 1 are provided with polarizer layers 3, 4.

The magnetic layer 2 of the rare earth iron garnet allows the changing of the direction of the magnetization in the respective parts with the simple recorder, such as the magnetic pen, and is, therefore, easy to handle.  Plastic films, glass plates, etc., which are inexpensive and are formable to the larger area are usable for the substrate 1.
