Title: Lithographic printing method
Inventor: NAKAZAWA YUSUKE
IPC: B41F7/02
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To prepare a clear quality image inexpensively by a method in which in lithographic printing in which the image is formed on a plate material on the basis of image data by using a printing plate, the image is formed on the plate material by an ink-jet process in which an oily ink is ejected by using an electrostatic field. SOLUTION: The head 22 of an ink-jet recording apparatus has a slit held between upper and lower units, the tip of the slit is a discharge slit 22a, a discharge electrode 22b is arranged in the slit, which is filled with ink 23. According to the digital signal of image pattern information, voltage is applied to the electrode 22b, so that an oily ink is ejected from the discharge slit 22a toward a plate cylinder 11 to be a counter electrode to form the image on the plate material 9 on the plate cylinder 11. Preferably, the oily ink is prepared by a method in which hydrophobic resin particles which are solid at an ordinary temperature are dispersed in a non-aqueous solvent 109 Ωcm or above in specific resistance and 3.5 or below in dielectric constant.

Title: Compaction treatment system
Inventor: IWABUCHI MASATO
IPC: H01L21/82
Filed: 1990-01-19
Abstract: PURPOSE:To enhance an integration density as desired by a compaction opera tion and to prevent that an interconnection resistance and a parasitic capacity are increased or become irregular by the compaction operation by a method wherein a pattern is compacted from the lower-rank side of a tree structure grasped from a slice structure and terminals of adjacent patterns are aligned. CONSTITUTION:Since a pattern is compacted from the lower-rank side of a tree structure grasped from a slice structure and terminals of adjacent patterns are aligned, a treatment on the upper-rank side acts in such a way that it does not affect a treatment which has been already completed on the lower-rank side. Consequently, adjacent cell blocks of the slice structure which can be expressed as the tree structure can be connected directly at terminals without a need for a special bent interconnection. Thereby, an integration density can be enhanced as desired by a compaction operation, and it is possible to prevent that an interconnection resistance and a parasitic capacity are increased or become irregular by the compaction operation.

Title: Voltage control oscillator
Inventor: ERUNSUTO FUUGO NORUDOHORUTO
IPC: H03B5/02
Filed: 1989-01-19
Abstract: PURPOSE: To set up idling frequency, frequency drift and sensitivity by frequency determining elements by providing the voltage controlled oscillator with an amplifier for supplying an output signal from a phase detector to the control input part of a phase rotation circuit network in an oscillator loop and providing the phase detector with I/O relation independent of temperature. CONSTITUTION: An input signal and an output signal to/from the phase rotation circuit network 2 are sent to the input part of the phase detector 4 and the phases of the two signals are mutually compared by the detector 4. An output signal from the detector 4 is filtered at its low band through a filter 5 and the filtered signal is supplied to the control input part of the network 2 through a high gain amplifier 6. When a control signal is sent to an adder circuit 7 for the amplifier 6, the network 2 automatically generates a phase shift corresponding to the output signal of the detector 4 and having size equal to that of the control signal and a reverse sign. Thereby the phase detector 4 has phase sensitivity accurately determined and independent of temperature.  Consequently the idling frequency, frequency drift and sensitivity can be completely determined by the frequency determining elements.

Abstract: PURPOSE:To enable inspection of general defects, such as nonuniformity in the film thickness of a minute part and a defect of a photosensitizing agent surface due to an extraneous substance, in a short time by intercepting a light of a short wavelength of a white fluorescent lamp, by forming it as a perfect diffusion surface illuminant and by applying a light diffused perfectly thereby to a substance to be inspected. CONSTITUTION:An illuminating device 1 is provided with color filter glass 1b (for which a transmission limit wavelength is 520 to 560 nm preferably) for intercepting a short- wavelength light in front of four white fluorescent lamps 1a, and with blue plate glass 1c and opaline glass 1d for diffusing light perfectly in front of the glass 1b. A glass board 2 coated with a photosensitizing agent 3 is illuminated by the illuminating device 1 and inspection is made by the naked eye. The eye is positioned on the occasion so that an angle of reflection to the surface of the glass board 2 is about 60 deg.. When a light diffused perfectly by a perfect diffusion light source thus constructed is applied in this way, a light (solid line) passing through a defect part and a light (dotted line) passing through a normal part are seen with different colors between then. Accordingly, a very slight difference in color of a minute part caused by a minute defect of the surface of a substance to be inspected can be observed and discerned distinctly.
