Inventor: MOCHIZUKI MASARU
IPC: H04B1/26
Filed: 1989-09-06
Abstract: PURPOSE:To reduce or suppress fluctuation of a local oscillating frequency and to decrease a tracking error by using two variable capacity diodes in anti- parallel connection for a resonance circuit of a local oscillation circuit and impressing a control voltage to the diodes in a way that one terminal voltage is increased while the other is decreased. CONSTITUTION:A resonance circuit 40 has two variable capacity diodes 42, 43 in anti-parallel connection. A local oscillation circuit 13 is oscillated in a resonance frequency according to a tuning voltage Vsym, then when a terminal voltage of one variable capacity diode 42 (43) is increased according to the phase of the oscillated frequency signal, the terminal voltage of the other variable capacity diode 43 (32) is decreasing. Thus, even when there is any nonlinearity in the capacitance versus voltage characteristic of the variable capacity diodes 42, 43, so long as the tuning voltage Vsym is constant, the degree of change in the combined capacitance of the variable capacity diodes 42, 43 in following an AC voltage change of the oscillating voltage is decreased substantially to ignocable degree and the local oscillating frequency is made stable.

IPC: G01R31/02
Filed: 1988-09-13
Abstract: PURPOSE:To inspect conductivity of a through hole from existence of a plated layer formed on an edge of the through hole by plating the through hole exposed on a ceramic substrate surface. CONSTITUTION:A conductive coat layer 3 is formed by electrolytic plating, sputtering, evaporation, etc. on one surface 1a of a ceramic substrate 1. Then, plating solution is put into a plating bath 4, and the substrate 1 is formed with the conductive coat layer 3 formed, and with an electrode board 6 located opposite to each other, voltage is applied from a power source for plating 5. Since a through hole 2 has a diameter of approximately 100 to 200mum, it becomes completely conductive or does not become conductive at all. If the ceramic substrate 1 is thus plated, a plated layer 7 is formed on an edge of the through hole 2 on the other surface 1b of the ceramic substrate 1 when the through hole 2 is conductive, and if the through hole 2 is not conductive, no plated layer 7 is formed on the edge of the through hole 2 on said side 1b of the substrate 1.

Title: Reflection mask, exposure apparatus, and manufacture of integrated circuit
Inventor: MURAKAMI KATSUHIKO
IPC: G03F1/24
Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To prevent the line width of a circuit pattern transcribed on a wafer from being affected by the unevenness of the reflectance of a reflection mask, by making unfixed and different from each other the extendedly existent periodic lengths of a multilayer film along its lamination direction. SOLUTION: On a substrate 1, a multilayer film 2 is formed to form thereon an absorbent layer 3 having a predetermined circuit-pattern shape, and the periodic lengths of the multilayer film 2 are made unfixed to vary them in the course of its lamination. That is, by dividing the multilayer film 2 into first and second blocks having two respective periodic structures, the first block is laminated at a periodic length d1 and the residual second block is laminated at a periodic length d2 changed in the course of the lamination of the film 2. Also, the multilayer film 2 is so laminated that its initial layer present on the side of the substrate 1 is formed at the periodic length d1, and the periodic length of its layer becomes dN on its surface side.  In this way, by changing the periodic lengths of the multilayer film 2 in the course of its lamination, the half-value width of its reflectance curve versus the wavelength of a projection beam can be expanded. As a result, the yield of the manufacture of a reflection mask is improved to make reducible its manufacturing cost.

Title: Data separate circuit
Inventor: HAYAKAWA HISATO
IPC: G11B20/14
Filed: 1990-08-31
Abstract: PURPOSE:To generate a stable data window by outputting only a down signal in proportion to delay time by a phase comparator based on delay time information while holding the delay time when the pulse of a pulse trains delays the phase to a feedback signal for phase comparison. CONSTITUTION:When comparing the phase of a read data pulse with that of the signal for phase comparison having the double frequency of transfer speed generated by frequency-dividing the output of a voltage controlled oscillator 3 in a field where the read data pulse trains are not arranged at equal intervals, a holding means 9 holds the delay time in the case that the read data pulse delays the phase to the signal for phase comparison. When the read data pulse exists with the 1/4 time of the transfer speed, a phase comparator 8 actuates the down signal only for the held delay time and when the read data pulse does not exist within the 1/4 time of the transfer speed, the down signal is not activated. Thus, the stable data window reducing jitter is outputted, and a stable data separate operation is enabled.

Abstract: PURPOSE:To enhance the accuracy of measurement using Pockels effect by eliminating errors in measurement which depend on the double refraction temperature characteristic of a phase difference plate. CONSTITUTION:Outgoing light I0 from a light source 31 is converted by a polarizer 32 into linearly polarized light, which is then given a phase difference pi/2 by a quarter wavelength plate 33 and separated by an analyzer 35 into P- polarized light and S-polarized light after application of an AC voltage V thereto using a Pockels element 34.

The electric signals V1, V2 are input to respective arithmetic circuits 38a, 38b and outputs V11, V12 are calculated from equations: V11=(V1-DC1)/DC2; V22=(V2-DC2)/DC2; DCn is the DC component of Vn. At an arithmetic circuit 38c, an equation V3=1/(alpha/V<11>-beta/V22) is computed and a voltage or an electric field is calculated from its output value V3. Errors depending on double refraction temperature characteristic can be eliminated by setting of alpha, beta to adjusted values.

Title: Measuring method and apparatus of loss coefficient of wave guide
Inventor: TAKESHIGE KUNIHIKO
IPC: G01N25/20
Filed: 1989-09-07
Abstract: PURPOSE:To easily measure transmission loss by measuring an increase of temperatures because of the thermal energy generated through absorption of a guided light by a metal on a waveguide. CONSTITUTION:A light from a semiconductor laser 4 as a light source is connected to a wave guide 2. A mercury 1 is provided on the waveguide 2. Therefore, a guide light P is absorbed by the mercury 1. Approximately the whole of the energy of the light P is absorbed by the mercury 1, which is converted to thermal energy and raises the temperature of the mercury 1. This increase of temperature is converted to electric signals by a thermocouple 3. At this time, the laser 4 is pulse-driven because of an increase of S/N, and the electric signals are amplified by a lock-in amplifier 5. The signals are plotted by a pen recorder 6 with a logarithm to a transmitting distance L of the light. In this manner, an increase of temperature generated through pulse-driving of the laser 4 is measured by a temperature measuring device at least at two points since the mercury 1 is moved. After the results are integrated, they are recorded by a recording device.
