Title: Voltage control oscillator
Inventor: WATANABE HIDEAKI
IPC: H03B1/04
Filed: 1986-06-20
Abstract: PURPOSE:To obtain a voltage control oscillator that can keep the highly accurate modulation characteristics by absorbing the resonance mode to a double wave and attenuating this resonance among those high-degree resonance modes to the basic wave of a secondary resonance circuit. CONSTITUTION:This voltage control oscillator contains the secondary resonance circuit consisting of a strip line 3 and a varactor diode 5 connected to the line 3. A resonance attenuating means is set at a position distant from the tip of the line 3 by about 1/4 wavelength against a frequency double as much as an oscillation frequency. The resonance attenuating means uses a chip resis tance 2 connected in series between strip lines or a radio wave absorber 6 fixed onto the strip line 3. Thus the attenuating means absorbs the resonance mode equivalent to the double as much as a basic wave and attenuate the resonance. Then the highly accurate modulation characteristics can be main tained.

Title: Eye pattern monitoring device
Inventor: MATSUI HITOSHI
IPC: H04L27/38
Filed: 1987-06-10
Abstract: PURPOSE:To easily observe the deterioration of a signal point by varying the brightness of the signal point according to whether a signal obtained by comparing signals before and after a decision device decides is larger or smaller than a constant value. CONSTITUTION:A comparing means is provided, which compares as to which is larger between the absolute value of the difference between a demodulated signal and a decision signal and a prescribed value and applies a voltage corresponding to the comparison result to the brightness modulation terminal of an oscilloscope 5. Namely, when a received signal has small deterioration, a signal point on an eye pattern comes close to a reference point, but when the deterioration is remarkable, the signal point leaves the reference point. In this case, signal points within a constant distance range from the reference point are displayed as dark signal points and signal points which are not within the distance range are displayed brightly. Therefore, the deterioration state of a received signal is easily decided.

Title: Forming method of resist pattern and production of semiconductor device
Inventor: WADA HAJIME
IPC: G03F7/40
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To form a pattern of a size smaller than the resolution limit of an aligner by expanding the resist pattern after the pattern is formed in a photoresist. SOLUTION: A resist film 26 is exposed and developed to form a resist pattern 28, and then the whole surface of the resist pattern 28 is exposed. Then the semiconductor substrate 10 is introduced into a vacuum chamber, which is evacuated. Then as the semiconductor substrate 10 is held at 150 to 180 deg.C, an acetyl chloride gas is introduced into the chamber to carry out the reaction of the resist pattern 28 and the acetyl chloride gas. On the resist pattern 28, the chemical reaction proceeds to increase the volume, which reduces the size of the punched pattern to form a contact hole. Then the expanded resist pattern is used as a mask to etch the interlayer insulating film 24 so as to form a contact hole which exposes source-drain diffusing layers 20, 22. Thus, the aperture diameter of the contact hole can be reduced smaller than the resolution limit of an aligner.

Abstract: PURPOSE:To prevent shortage of charging caused by wrong contact with a trolley wire, and facilitate starting after a long time stoppage by a method wherein, when a trolley wheel stops, a charging current to a battery mounted on a trolley wheel is detected, and, when the detected value is smaller than the prescribed value, the trolley wheel is moved, and when the detected current becomes the normal state, the trolley wheel is stopped. CONSTITUTION:A motor 14 is driven 13 by a battery 11 mounted on a trolley wheel 1, and a wheel 4 is rotated to move the trolley 1 along a rail 2 to stop the trolley at the prescribed position. At this time, a current charged from trolley wire 6, 7 to the battery 11 through brushes 8, 9 is detected by a current detection circuit 10. When the detected value is smaller than the prescribed value, a control circuit 12 energizes the motor 14 through a driving circuit 13, and when the detected current restores to the normal value, the motor is stopped. In this way, the shortage of charging caused by wrong contact of the trolley wires 6, 7 with the brushes 8, 9 can be prevented, and restarting can be surely effected even after a long time stoppage.

Title: Second harmonic wave generating device
Inventor: IKEDA SOTOMITSU
IPC: H01S3/109
Filed: 1988-06-14
Abstract: PURPOSE:To increase conversion efficiency, and realize high density integration by arranging a second harmonic wave generating region composed of II-VI compound semiconductor crystal, on a semiconductor laser layer composed of III-V compound semiconductor, and providing a diffraction grating at a position, in the region, where laser light diffracted by a diffraction grating in a semiconductor laser arrives. CONSTITUTION:A second harmonic wave generating region (SHG region) II is constituted of II-VI compound semiconductor crystal. For example, epitaxial growth is enabled on an AlGaAs system semiconductor laser, and the SHG region II can be easily formed in a unified body. Since the fundamental wave from the semiconductor laser I couples with the SHG region II without passing the external space, the intensity of the fundamental wave can be increased. By a diffraction grating GI in the semiconductor laser I, the fundamental wave generated from the semiconductor laser I is diffracted in the direction of the SHG region II and introduced. By diffracting the introduced fundamental wave with a diffraction grating GII in the SHG region II, the fundamental wave is effectively converted into the second harmonic wave. Thereby high density integration is enabled, and the conversion efficiency is increased.

Abstract: PURPOSE: To individually perform optical reflection measurement of the respective branched transmission lines of an optical subscriber transmission line in one-to-multiple connection by respectively setting specified filter means. CONSTITUTION: When discontinuity is present on the branched transmission line to an optical subscriber equipment 4, in an optical reflection measurement device 5, reflected light from a discontinued point is observed. Further, only the variable wavelength filter 7 of the branched transmission line connected to one optical subscriber equipment 4 is turned ON and the others are turned OFF.

When no reflected light is present, it is clarified that no discontinuity is present on the branched transmission line.  Similarly, even when discontinuity is present on more than two branched transmission lines and when the plural optical subscriber equipments 4 are arranged in an equal distance from a star coupler 2, the respective branched transmission lines are separately measured and the position of the fault point is discriminated.

Title: Method for storing holography and device thereof
Inventor: ROGER MORTON MACFARLANE
IPC: G03H1/04
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To obtain a memory system having reliability at a low cost by allocating the individual stages consisting of two stages consisting of an excitation stage and ionization stage to separate dopants. SOLUTION: A first coherent radiation ray of a first wavelength is split to a reference ray and a spatially modulated objective ray. The reference ray and the modulated objective ray are intersected with each other within the memory region of a holography memory medium and simultaneously the second radiation of the second wavelength is sent to the memory region. The photons from the first and second rays are absorbed by the excitation dopant and the electrons are successively progressed upward from the base state of the excitation dopant to the second excitation state of the excitation dopant existing under the transmission band of a host medium. Next, the electrons are progressed upward from the first excitation state to the second excitation state of the excitation dopant again existing under the transmission band of the host medium.  At the time the electrons attenuate thereafter, the energy transfers from the excitation dopant to the ionization dopant and generates charge carriers. The ionized electrons or holes form charge diffraction gratings in the memory medium.
