Title: Method and device for producing ecr plasma
Inventor: FUJIYAMA HIROSHI
IPC: C23C16/511
Filed: 1992-03-14
Abstract: PURPOSE:To suppress the production costs by using together a weak magnetic field and a ferromagnetic body, thereby preparing the ECR conditions effectively, and reducing the amount of current feed to a coil for generation of a magnetic field. CONSTITUTION:A certain specified current is fed to a magnetic field coil 12 in the condition that the inside of a plasma generation device is maintained at a certain pressure level with argon gas, and a magnetic field having an axially oriented distribution is generated. Therein a ferromagnetic body is installed at a specified position in the device, and thereby a resonant magnetic field is produced to provide a magnetism having a required intensity. If microwaves are released into the device through a micro-coaxial line 11, an ECR plasma can be generated by this magnetism of the resonant magnetic field. The current to be fed to the coil can be much smaller at this time than in the case a magnetic field of required intensity is to be formed solely. This allows suppressing the production cost where ECR plasma is applied.

Filed: 1989-04-11
Abstract: PURPOSE:To temporarily store a printed matter to be kept secret from the third person and to print it out on demand by printing data stored in a storage device only at the time of input of a prescribed password from a password setting device. CONSTITUTION:Not only input data but also a password is sent from a host computer 1 to the printer side. If the password is not sent together with input data, normal processing is performed to execute printing. When the password is set, input data is stored in a user memory 10 together with the password. That is, the password is inputted by a password set switch 9, and the memory 10 is retrieved by the password. When the user memory 10 coinciding with the inputted password exists, normal processing is performed to terminate printing. Thus, the printed matter to be kept secret from the third person is temporarily stored and is printed out on demand.

Title: Fluorescent type liquid crystal display device
Inventor: TANI KAZUTSUKA
IPC: G02F1/137
Filed: 1980-07-02
Abstract: PURPOSE:To obtain high contrast storage dispaly without the inhibition of fluorescence by applying vertical grade processing to the surface of an electrode substrate, using a cholesteric liquid crystal with negative induction anisotropy and arranging the spiral pitch of the liquid crystal and the thickness of a layer so that they have a specific relation with each other. CONSTITUTION:When voltage is not applied, liquid crystal molecules and fluorescent molecules are arrayed vertically and the fluorescence energized by incident light from the external is generated in parallel with substrates 1 and 2, looking as if the whole surface of a cell is dark. When voltage is applied, DSM is generated and light scattering status is continued also after removing the voltage. The fluorescence is also scattered and discharged to the outside of the cell. The relation between the pitch (p) of liquid crystal and the thickness (d) of layer is regulated to 0.5 d/p 1. When the relation is not satisfied, light scattering status is not stably continued. Especially when d/p 1, vertical array is not formed at no voltage, so that effective display is disabled.

Title: Digital broadcast receiver
Inventor: KATSUMOTO YOJI
IPC: H04B1/16
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To allow a receiver to receive transmitter identification information without errors. SOLUTION: When an antenna 1 catches a digital audio broadcasting(DAB) signal, the signal undergoes high frequency amplification and frequency conversion at a front end 2 with the result being I/Q-demodulated by an I/Q demodulation circuit 31, and an FFT circuit 32 extracts a carrier-wise component. Carrier-wise power detection circuits 41, 50 obtain a carrier-wise power, consisting of a NULL symbol part and a carrier-wise component of a PRS part. A correction amount decision circuit 51 calculates the ratio of the carrier- wise component to the mean values of all carriers for each carrier as to the PRS part to determine a correction amount. A correction circuit 52 corrects the carrier-wise component for the NULL symbol part by using this correction amount.  A transmitter identification information signal (TII) decoding circuit 42 discriminates a transmission carrier from the carrier-wise component of the NULL symbol part after the correction to decode the transmission identification information, based on the discriminated transmission carrier.

Title: Semiconductor integrated circuit device
Inventor: MOGI KENJI
IPC: H01L21/8244
Filed: 1987-04-15
Abstract: PURPOSE:To obtain a high resistance value required in a fine region by a method wherein the load resistance is obtained by making use of a Schottky barrier to be caused when a semiconductor is connected to a barrier metal. CONSTITUTION:A high-resistance region 11 is formed inside a contact hole which is connected to a drain of a MISFET Q4 via a high resistance value, e.g., a barrier metal 12 which constitutes a Schottky barrier diode by connection to the drain is formed. By this setup, a power source voltage supply line 8 to supply a power source voltage is brought into contact with the drain of a driver MISFET by using the high resistance value. As a result, because the high resistance is formed inside a contact region, a region to form a resistor becomes unnecessary as compared with a conventional method; it is easy to realize the high integration density.
