Title: Formation of electrically conductive carbon film
Inventor: MIZOGUCHI AKIRA
IPC: C23C14/32
Filed: 1987-01-27
Abstract: PURPOSE:To obtain a carbon film having high electrical conductivity even when the temp. of a base material is lower than the conventional temp., by forming a carbon film on the base material heated to a relatively low temp. by an ion beam process with a hydrocarbon as starting material. CONSTITUTION:A quartz base material 7 is fitted to a base material holder in a chamber 1 and the chamber 1 is evacuated to 1-2X10<-4>mmHg with an evacuating device composed of a rotary oil pump 20 and a diffusion oil pump 21. A hydrocarbon as starting material 2 is jetted from the nozzle 6 of a crucible 3 and voltage of several ten - several hundred volts is impressed between an electron emitting filament 12 and an electron accelerating electrode 16 to emit electrons toward beams 15 of the starting material and to ionize the starting material. This ionized starting material is accelerated toward the base material 7 heated to 400-<900 deg.C by an ion accelerating electrode 13. Thus, a carbon film having superior electrical conductivity is formed on the surface of the base material 7 at the relatively low temp. Methane or ethane may be used as the hydrocarbon.

IPC: H04B10/556
Filed: 1979-02-13
Abstract: PURPOSE:To obtain the digital signals by supplying both the data signal waveform and the call signal waveform to the modulator in the alternate switching and then giving the sampling with the frequency which is higher enough than the data signal frequency, thus amplifying the system constitution. CONSTITUTION:The data signal sent from data transmitter 1 is D/A-converted through modulator 21. And the call signal from telephone transmitter 11 is supplied directly to switch unit 22 since it is the analog signal. The both signals are switched in the time-division way through unit 22, and both the data signal and the call signal are sampled together at DELTAM modulator 23 and with the frequency which is higher enough than the frequency of the data signal. And one pulse of the data signal is converted into the digital signal of plural bits and then into the optical signal through photoelectric converter 2 to be converted again into the electric signal through photoelectric converter E2'. After this, the electric signal is converted into the analog signal through DELTAM demodulator 23' to be divided into the data signal and the call signal each through switch unit 22' to be sent to data receiver 1' and telephone receiver 11' directly each.

Title: Ofdm signal transmitter
Inventor: MITSUBORI SHIGERU
IPC: H04N7/08
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To enable adaptive copings against interference to an orthogonal frequency division multiple(OFDM) signal which has been difficult in conventional methods and the effective utilization of a frequency. SOLUTION: This OFDM signal transmitter 21 receives and demodulates an OFDM signal that is sent from an OFDM transmitter 22 by an OFDM receiver 23 and reads a frequency spectrum of an interference wave in a null symbol period from the demodulation data by an interference wave detection circuit 236. A mapping control circuit 226 adaptively changes the position of a carrier hole by sending an instruction to a mapping circuit 222 of the transmitter 22, based on the interference wave information. Also, when an interference wave is not detected, data transmission such as communication usage is allocated in place of a carrier hole.

Title: Current detector
Inventor: NUKUI TADASHI
IPC: G01R15/20
Filed: 1994-02-10
Abstract: PURPOSE:To automatically compensate an unbalance component of Hall element by counting the output pulse corresponding to the unbalance amount of output voltage of the Hall element. CONSTITUTION:A Hall element 1 to which a current converted 2 from voltage and a magnetic field converted from measured system current by a core are inputted outputs a voltage proportional to the product of the current and magnetic field. The output voltage is amplified 4 and a voltage C which is sign- inverted by an inversion amplifier 5 is inputted by an output terminal 20. At this time, a comparator 6 outputs a voltage E at an H (L) level when the voltage C is higher (lower) than reference potential. An up/down counter 9 whose counter value is preset to be 32768 up- (down-) counts the voltage when the voltage E is at the H (L) level, and the result becomes larger (smaller) than 32768 when the polarity of the unbalance amount of the output voltage of the element 1 is positive (negative). A compensation calculation part 10 calculates the difference to find out the compensation value of unbalance components, and a variable resistance element 7 changes the resistance value with the converted 11 output voltage and makes the unbalance component of the element to be zero.

Abstract: PROBLEM TO BE SOLVED: To prevent an observer from closing one eye and putting a cap on a lens to simplify the adjustment operation of diopter difference by providing a covering means respectively covering the visual fields of right and left telescopic optical system. SOLUTION: LCD panels 51 and 52 for selectively shielding each visual field are provided behind left and right visual field frames 16 L and 16 R. The panels 51 and 52 separately operate by a driving voltage sent from a control part 100. The panels 51 and 52 shield light when a voltage is impressed and transmit light when the voltage is not impressed. That is, the visual field of wither one of telescopic optical system 10 L and 10 R on the LCD panel on which the driving voltage is impressed is shielded, visual field of the other telescopic optical system on the LCD panel on which the driving voltage is not impressed is shielded, so that the visual field of the telescope optical system on the LCD panel of which the driving voltage is not impressed can be observed.  Thus, the visual fields of the left and right system 10 left and 10 right are successively shielded by the panels 51 and 52, so that the adjustment for the diopter difference can be performed while the observer looks at the binoculars with both eyes.

Abstract: PURPOSE:To obviate the occurrence of off-track at the positioning of head even if the spindle part inclines owing to the change of environmental temperatures by so arranging the apparatus that the direction of the tension of belt being exerted to the spindle part becomes orthogonal to the seek direction of carriage. CONSTITUTION:The spindle part 3 of a revolving shaft 1 concentrically fixed with plural sheets of discs 10 at a specified pitch is turnably supported via bearings 5, 5' to a housing 4 and revolves by being driven by a motor 22 via pulleys 21, 24 and belt 25. A motor 21 is disposed in the position deviated from the ordinary line a-a. The motor 21 and tension pulley 24 are provided in the positions symmetrical to the line b-b orthogonal to the line a-a running the center of the spindle part 3. As a result, the direction of the tension of the belt 25 being exerted to the spindle part 3 is orthogonal to the seek direction of the carriage 2. Hence, even if the spindle part 3, i.e., discs 10, incline upon changing of environmental temperatures, this becomes irrespective from off-track, thus the problem of off-track at the head positioning may be prevented.

Title: Resist coating method
Inventor: ENDOU SHIYUUJI
IPC: H01L21/027
Filed: 1978-02-17
Abstract: PURPOSE: To prevent the second dispersion of the linear resist onto the substrate from the periphery of the substrate and thus to obtain the flat pattern by giving the spin-coating of the resist onto the substrate while spraying the inactive gas to the surface to be coated.  
     CONSTITUTION: The Si substrae is rotated at 4000rpm, and the positive resist of 35cp viscosity is dropped down to the center. At the same time, the N 2  gas is sprayed toward the center and vertically to the substrate. Thus, no linear protrusion is caused to the coated resist. Also, the exposure is given via the electron beam to secure the 1μm inter-line space after the pre-baking, and then the development is given with the methyl isobutyl ketone solution. After this, no linear resist is left at the inter-line space even though the after-baking may be applied. As a result, a high-accuracy pattern can be obtained when the Al film pattern is formed on the resist.
