Title: High frequency change-over circuit
Inventor: OIKAWA KAZUO
IPC: H01P5/12
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To provide a compact high frequency switching circuit which secures its stable characteristic in a wide band by performing the bias separation and the cut-off of signal transmission and the signal transmission line between both elements by means of a DC cut filter. SOLUTION: A bias circuit is changed-over so that an FET 13 of the 1st input line side and an FET 23 of the 2nd input line side are turned on and off respectively. In such cases, the input signal is amplified with low noises by an amplifier circuit of an FET 13 and transmitted to an output terminal 50. Thus, the FET 23 is turned off and the impedance Z2 has a high level when the FET 23 is viewed at a point B where the 2nd input line is connected to a DC cut filter 30. Therefore, the signal transmission is cut for a line 32 of the filter 30. As a result, the input line of the turned-off FET 23 can be disregarded and only the input line of the turned-on FET 23 is connected to the terminal 50 via the filter 30 in this switching circuit.

Title: Small size measurement
Inventor: NAKADA HIDEFUMI
IPC: G01B21/02
Filed: 1978-10-16
Abstract: PURPOSE: To improve the measuring accuracy by dividing and differentiating the size signals.  
     CONSTITUTION: The size signals 4, which are generated by the scanning operation of such a pattern 1 in the direction of arrow 3 with electron beams as is formed in submicron unit on a substrate 2 and as is made of chromium or silicone oxide film, are suitably divided in an X (or vertical) direction so that the maxiumum or minimum is sampled in each divided section. After the division into one signal waveform by the maximum only and into the other signal waveform by the minimum only, the respective signal waveforms thus divided are differentiated to take out the respective peak values of the differentiated waveforms, from which the respective center values are calculated to determine the size of the pattern 1. Thus, even if the S/N ratio of the signals 4 is not good, the correct signals can be taken out, and the end portions of the pattern 1 can be properly grasped thereby to attain the desired object.

Title: Measurement of pulse width
Inventor: HIBI MICHIO
IPC: G01R29/02
Filed: 1983-07-13
Abstract: PURPOSE:To eliminate errors possible in the results of measurement by determining a pulse width depending on a shift of a clock phase shifting circuit with the control of computation/control/memory circuit. CONSTITUTION:A bit synchronization circuit 4 counts a bit error rate with an error counting circuit 7 depending on a clock phase shifted and a computation/ control/memory circuit 8 computes and memorizes the results to control a clock phase shifting circuit 9 until the shifting of the clock phase is ended equivalent to one bit of data. This operation is repeated and the control is stopped when the shifting of the clock phase is ended equivalent to one bit of data. Meanwhile, the shift in the clock phase of the circuit 9 is determined as measured value with the pulse width of a digital waveform. This enables the measurement of the width of a phase jitter even in the pulse width of a signal pattern other than repeated signals thereby eliminating errors in the results of the measurement.
