Title: Electron beam testing method and electron beam tester
Inventor: FUJIOKA KAZUMICHI
IPC: G01R31/302
Filed: 1987-05-27
Abstract: PURPOSE:To enable the precise quantitative measurement of the potential contrast image of a wiring electrode under an insulating film without eliminating the insulating film, by applying and cutting a bias voltage with a period longer than the time interval in which the potential contrast image vanishes just after the applying and cutting of bias. CONSTITUTION:A sample 4 is arranged on a socket 3 in the state where a chip is exposed. The inside of a sample chamber 1 is set in a specific atmosphere, and an electron beam 6 is projected into the sample chamber 4. The sample 4 is operated by a bias applying equipment 8. Just after the bias is applied, and just after the bias is cut off, potential contrast images generate, respectively.

Title: Measuring system of azimuth
Inventor: NOMI HITOSHI
IPC: G01S1/32
Filed: 1990-05-18
Abstract: PURPOSE:To obtain a necessary azimuth resolution and a precision superior to the measuring precision of VOR by determining an azimuth angle by transmitting signals from a plurality of transmission antennas on the transmission side in a prescribed sequence and at a prescribed time interval and by detecting a change in phase of each reception signal on the reception side. CONSTITUTION:An antenna switching circuit 2 supplies an output of a transmitter 3 to a transmission antenna group 1 comprising a plurality of transmission antennas, by switching them in a prescribed sequence and at a prescribed time interval. The transmitter 3 outputs a modulated high-frequency signal during the period of a specific transmission antenna (a reference signal period) and delivers an output of an oscillator, as it is, during the remaining period (a measuring period). A signal from a ground-side apparatus enters a reception circuit 21 from a reception antenna 20 and is outputted therefrom to a signal separating circuit 22. The signal separating circuit 22 outputs a signal in the reference signal period to a phase synchronous oscillator 23 and a signal in the measuring period to a phase detecting circuit 24. Using an output of the phase synchronous oscillator 23 as a reference signal, the phase detecting circuit 24 detects the phase of the output of the signal separating circuit 22 and outputs phase change information to an azimuth computing element 26. A resolution is improved in proportion to the number of the transmission antennas.

Title: Detecting circuit of signal level
Inventor: HIGASHIYAMA NAOTOSHI
IPC: H04N5/94
Filed: 1981-08-17
Abstract: PURPOSE:To detect the dropout of a frequency modulated wave, by providing a phase  comparator in addition to the phase comparator that demodulates the frequency modulated wave of a video disk and adding the output of a voltage control oscillator to the  phase comparator via a phase shifter to perform synchronizing wave detection. CONSTITUTION:The frequency modulated wave of a video disk is amplified by an  intermediate frequency amplifier 1. A voltage controlling oscillator 2 oscillates the  frequency approximate to a signal wave. The output of the oscillator 2 is applied to a  phase comparator 3 to be compared with the output of the oscillator 2. The output of  comparison is turned into the control signal for the oscillator 2 as well as into the  demodulated signal after the high frequency is eliminated through an LPF4. The output of the amplifier 1 and the output of the oscillator 2 obtained via the phase shifters 6 and 7 are applied to a phase comparator 5. Thus the comparator 5 works as a synchronizing wave detector. The input signal of the comparator 5 is set at zero for a  period during which the dropout is caused for the frequency modulated wave. As a  result, no voltage is caused at the output terminals 8 and 9. The voltage is produced  when the normal input signal exists. Therefore the dropout of the modulated wave can  be detected by the presence or absence of the difference voltage between the terminals 8 and 9.

Filed: 1985-06-13
Abstract: PURPOSE:To remove an unnecessary circuit holding by stopping the sending of a circuit connection specifying signal and disconnecting a circuit when a terminal controller decides the unnecessity of communication with a terminal equipment and executes the processing. CONSTITUTION:When a host interface signal ER is turned on, signals DSC, CI outputted from an NCU interface are turned on and a flip flop FF1 is turned on, so that line active status is set up. Consequently, a DR signal ON is informed to the host interface. Similarly, CML signal ON is informed to an flip flop FF2 and the connected status of the circuit is held. Thus, unnecessary circuit holding can be removed by controlling the flip flops by an MPU.

Abstract: PURPOSE:To detect a slip of an original at the transmitter side, by making an arrangement that picture signals of one line are stored and picture signals of the n-th line from the line of the stored picture signals are compared with the stored picture signals, and when they coincide with each other, an alarm is  given. CONSTITUTION:Picture information signals arrived through a telephone line, etc., are introduced into a terminal 1 and sent to a picture signal extractor 2. At the extractor 2, only picture signals are fetched and sent to one line memory. When picture signals of one line, namely, one main scanning, are accumulated in a line memory 4, picture signals of the next line are sent to another line memory 3 based on the instruction from a controlling circuit 12, and the picture signals stored in the line memory 4 are sent to a printing register 5. At this time, the picture signals sent to the memory 3 are compared with those delivered from the memory 4 at a comparator 7, and, when they completely coincide with each other, the comparator 7 puts out the output. When they do not coincide, the comparator does not put out the output. When the output is putted out, an alarm is given so that it is easily detected that the original slips at the transmitter side.

Abstract: PURPOSE:To provide a vibration damping device which may permit a minute displacement of a structure due to a wind pressure or a temperature change, etc. without any restrictions and absorb a sudden vibrational displacement due to an earthquake, etc., by fixing a cylindrical resisting member with a minute annular spacing defined between the same and an inner circumferential surface of a cylindrical member filled with a viscous material. CONSTITUTION:There is provided in a cylindrical member 1 a piston 9 fixed to an end of a rod 7 and formed with a through-hole 10 of a large diameter. A cylindrical resisting member 11 is fixed on an outer circumferential surface of the piston 9, and there is defined a minute annular spacing S between the cylindrical resisting member 11 and the cylindrical member 1. The spacing S is secured by a spacer 12. Owing to a viscous shear resisting force of a viscous material 18 filled in the minute spring S, there is created a small resisting force against a gentle relative displacement, while there is created a greatly large resisting force against a sudden relative displacement. A change in volume of the cylindrical member 1 is absorbed by extension and contraction of a bellows 14 mounted to a cap of the cylindrical member 1 so as not to generate an inner pressure.
