Title: Antenna system for reception of synchronizing broadcast
Inventor: TAKAHASHI AKIRA
IPC: H01Q1/32
Filed: 1984-04-02
Abstract: PURPOSE:To attain the stable reception among areas having the same level of electric power at the middle part between adjacent broadcast stations in a synchronizing broadcast system, by synthesizing the outputs of monopole antenna and multi-turn loop antennas formed on ferrite bars. CONSTITUTION:A whip antenna 11 is used to receive the electric fields, and bar antennas 12 and 13 formed by winding coils round ferrite bars are set orthogonal to each other to receive the magnetic fields. The outputs of antennas 12 and 13 are connected in parallel by an impedance matching box 14, and a capacitance is used to secure the parallel tuning between the outputs of both antennas 12 and 13 and the reactance of a loop antenna. This induced voltage is dropped by a transformer, etc. to secure the matching of impedance and then synthesized with the output of the antenna 11 by a synthesizer 15. Then this synthetic output is led to a receiver 16.

IPC: G02F1/133
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To suppress display unevenness and to obtain uniform display quality by converting a voltage pattern so that change points of the level of voltage applied to row electrodes in one selection period decrease in number, applying voltage to column electrodes and making a gradational display. SOLUTION: An MLA arithmetic circuit 13 reads gradation data 103 out of a frame memory 12. For example, 3-bit gradation data are read out and converted into 4-bit data representing an ON display or OFF display in each of four-divided selection periods, and data of virtual rows are generated corresponding to display data of three lines which are selected at the same time so as to set two levels of the voltage applied to the column electrodes in each divided period. A column data converter 14 converts the voltage pattern signal into a voltage pattern which generates no display unevenness.  Namely, the divided periods are provided in one selection period, the voltage pattern is converted so that the number of change points of the voltage level applied to the column electrodes is decreased, and the voltage is applied to the column electrodes according to the voltage pattern to make a gradational display.

In case an electric power supply B is sufficient in its capacity, an output of the detector S is "0", and CPU executes no operation. When the electric power supply B is working, if its capacity drops, an output of the detector S becomes "1", it is detected in CPU, and a flip-flop F1 is set to "1". By this set signal, a warning is displayed on its display part D. Moreover, an output of an inverter I becomes "0", a key signal from the keyboard part KB is inhibited, and it is not inputted to CPU.

Title: Reaction gas monitoring method and ion source for mass spectrometry used therein
IPC: H01L21/205
Filed: 1992-03-24
Abstract: PURPOSE:To provide an ion source and a semiconductor manufacturing device with a reaction gas monitor loaded with the ion source. CONSTITUTION:An ion source to be loaded on a reaction gas monitor attached to a semiconductor manufacturing device, is formed out of a V-shaped filament 1 and an electron lens 2 for shading, and a low temperature condition of an ionization chamber 3 is achieved. The gas pressure in the ionization chamber is increased by regulating the conductance of a gas leading port 8 in the periphery of the ionization chamber and of a gas discharging part 9, while the ionization efficiency is improved by controlling the movement of electrons in the ionization chamber by providing a magnet 6, and the monitor sensitivity is thus improved. The thermal reaction in the ionization chamber 3 is suppressed by reducing the temperature of the ionization chamber 3 to a no more than a threshold of the thermal reaction, and the noise level of output is reduced. Since the intensity of the signal of the output is increased by improving the efficiency of ionization of the molecule to be analyzed a measurement of high S/N ratio is achieved. A semiconductor manufacturing device that can monitor the reaction gas in a formed film is thus achieved.

Title: Mobile radio test system
Inventor: KOO HIDEO
IPC: H04B17/00
Filed: 1986-03-26
Abstract: PURPOSE:To eliminate the effect on a mobile station on a main line due to the leakage of a transmission signal at test by using two waves of different frequencies for the transmission signal. CONSTITUTION:In measuring the transmission output, a test equipment 3 starts a radio equipment 7 through a control cable 11 and the output is measured by the test equipment through a signal cable 10 via a coaxial relay 12. In testing the modulation, a transmission relay a16 is closed and the signal is modulated by the 1st transmission signal 8 and the result is measured by the test equipment. Similarly, a transmission relay b17 is closed and the modulation is measured by the 2nd transmission signal 13. Since the modulation degree is measured one by one wave sequentially in this way, even when the transmission signal leaked from an antenna 6 reaches a mobile station on the main line, only one of transmission signal receivers 9, 14 is operative, and since no output of a coincidence circuit 15 is given, it is impossible to send stop information to the vehicle and the mobile station on the main line is operated according to the schedule.

Title: Speed control system for moving body
Inventor: MISAKI YOSHINORI
IPC: H02P25/06
Filed: 1978-06-02
Abstract: PURPOSE: To accurately control the speed of a moving body even if the moving body is close to a destination, by setting a raised speed command lower than a reference speed to compensate the overshoot when the moving body is accelerated.   
     CONSTITUTION: When the moving body is started at a point (a) to move to the destination (c), the output of a subtraction circuit 3 selected by a switch circuit 4. When the moving body reaches an intermediate point (b), the switch circuit is shifted to select the output of a memory circuit 1. As a result, the moving body is accelerated between the points (a), (b) and the acceleration is stopped at the point (b). The overshoot takes place because of the inertia. The difference between the reference speed curve 5 and the raised speed command curve 6 is made in expectation of the overshoot. Therefore, the overshoot is compensated. This results in accurately controlling the speed even if the moving body is close to the destination.

On the other hand, the closing control of the upper stage movable guide vane 4 is continued, therefore, the hydraulic pressure fluctuation moves from the return path 5 to the flow path of a casing 6 and the pressure of the path 5 is reduced. When the pressure of the return path becomes higher than the specified value at that time, the closing control of the lower stage movable guide vane 2 is effected again. According to this method, only the specified pressure permissible for the return path 5 among the hydraulic pressure fluctuations is impressed.
