Title: Suction device of internal-combustion engine
Inventor: AOYAMA SHUNICHI
IPC: F02B23/08
Filed: 1984-10-23
Abstract: PURPOSE:To remove the deviation of a quench layer and reduce the exhaust quantity of HC by extending the top wall of a combustion chamber in the vicinity of a side where an opening and closing valve is not installed, toward the central direction of a combustion chamber thereby to form a squash surface confronting the top surface of a piston. CONSTITUTION:A vent roof type combustion chamber 4 is formed by a cylinder head 10 and a cylinder block 11. In this case, the cylinder head 10 forming the top wall of a combustion chamber in the vicinity of a first suction valve 1A largely extends in a substantially crescent shape toward the inner side of the combustion chamber 4 to form a squish surface 10a. According to this construction, when a piston 12 draws near to the upper dead center at the time of a compression stroke, suction air (squish surface) extruded out of a gap formed the squish surface 10a and the upper wall surface of the piston 12, flows at a high speed toward the central part of the combustion chamber 4. Accordingly, the fuel in the quench layer formed on the inner wall surface of the combustion chamber 4 in the vicinity of the first suction valve 1A, is guided toward the central part of the combustion chamber 4.

Title: Charged particle beam irradiating apparatus
Inventor: NAKASUJI MAMORU
IPC: H01L21/263
Filed: 1996-08-22
Abstract: PROBLEM TO BE SOLVED: To assure flatness of a face of a wafer or a mask on which a sample is put by removing dusts adhered to the face by irradiating a charged particle beam after introducing a reactive gas. SOLUTION: Gaseous oxygen is introduced from an oxygen bomb 51 via an oxygen supply pipe 47 into a sample chamber 30 in which an electrostatic chuck 32 for fixing a wafer 31 or the like is installed. When a beam current is flowed from an electron gun 3, the gaseous oxygen is formed into plasma by a charged particle beam, so that organic dusts 34 are oxidized to H2 O, CO2 , and CO. By exhausting these gases together with the gaseous oxygen by a vacuum pump 37, the dusts 34 are removed. A sample face position measuring device 27 for detecting abnormality in height in the Z direction of a sample face 31 and a mask face 12 is provided. When height abnormality is detected, a similar dust removing work is performed. Consequently, the flatness of the face of the wafer and the mask is assured.

IPC: G02B5/20
Filed: 1996-08-22
Abstract: PROBLEM TO BE SOLVED: To provide a uniform film in the application of a transparent protecting film material by performing a corona discharge processing after formation of a colored layer to reduce the ink repellency of a protruding part. SOLUTION: A protruding part 2, preferably, a protruding part 2 by black mask is preliminarily formed on a substrate 1. Thereafter, colored ink is sprayed by ink jet to form a colored layer 5, whereby a color filter is formed. After coloring the picture element part, ink repellency of the upper surface 4 of the protruding part 2 is removed by corona discharge treatment in order to form a transparent protecting film. Since not only the removal of the ink repellency of the part subjected to ink repelling treatment, but also the enhancement of hydrophilic and lipophilic properties of the whole base can be attained by the corona discharge treatment, satisfactory applicability of the transparent protecting film can be provided. The ink repellency of the protruding part 2 can be removed by a simple treatment just before the formation of the transparent protecting film, so that a bad effect such as discoloration of the picture element is hardly caused, and the productivity can be improved.

Title: Semiconductor device
Inventor: HIRAYAMA HIROMITSU
IPC: H01L21/822
Filed: 1984-10-22
Abstract: PURPOSE:To reduce output-waveform strain without easily using a filter, etc. by forming a conductor for grounding around an integrated circuit formed onto a semi-insulating semiconductor substrate, a pad for a terminal for an input and input/output signal lines. CONSTITUTION:A conductor 6 for grounding is arranged around bonding pads 1, 4 for input/output terminals to an integrated circuit 2 shaped onto a semi- insulating semiconductor substrate 3 and an input/output signal connecting line 5. Consequently, distances among the input/output terminal pads and the grounding conductor can be reduced remarkably, thus localizing the induction noise field of clock signals, which have been radiated within a range comparatively wider than chip size, near the clock input/output terminal pads. Likewise, a distance between the output terminal pad and the grounding conductor is also shortened, and the device is difficult to receive the induction noises of clock signals. Accordingly, the induction noises of clock signals in an output electrode can be minimized, thus easily improving the waveform strain of output signals.

Abstract: PURPOSE:To prevent effect of interference of a chrominance signal by providing a prescribed synchronizing relation between the sampling period and a color burst signal included in a composite picture signal in extracting a monochroic picture signal from a color composite signal. CONSTITUTION:A digital color composite picture signal Vd of a receiver 1 is given to a bus L. An OSC section 16 consists of a PLL to generate a sampling clock fs of an A/D converter 12. The frequency of a clock fs is set sufficiently higher than the maximum frequency of a color composite picture signal Va. The OSC section uses a PLL to apply phase lock to the period of the clock fs to one over an integer of the period of the color burst signal B. The sampling circuit 21 of the picture recorder 2 samples the signal Vd by using a sampling clock fs/m having a comparatively longer period. A 1/m frequency division circuit 25 frequency-divides the frequency of the clock fs of the receiver 1 to one over m (integer) to generate a clock fs/m. Thus, the clock fs/m has always a prescribed synchronizing relation to the signal B.
