Title: Method for inspecting appearance of soldering for printed board
Inventor: KIRA HIDEHIKO
IPC: G01N21/91
Filed: 1989-05-11
Abstract: PURPOSE:To accurately decide the propriety of soldering just by visually observing inspection by previously applying paint on a part of the solder fused surface of the end face of an electrode and detecting the remaining state of the paint after soldering. CONSTITUTION:The paint is previously applied on the part of the solder fused surface of the end face of the electrode of chip parts 13 and most of the paint remaining part is shielded by a solder fillet 15 after soldering. In the case of a defective in soldering, most of the paint remaining part is exposed on the solder fused surface as shown in a defective soldering part 11 provided so as not make solder wet, thereby easily deciding the propriety of soldering by visual observation. In the case that red paint is used as the paint, for example, the state of the red paint is image-picked up by an ITV camera 4 through an optical filter 18 which transmits only red color and expanded to perform the visually observing inspection, or in the case that fluorescent paint is used as the paint, for example, the visually observing inspection is performed with the quantity of the light emitted in accordance with the remaining state of the paint in a condition that the quantity of irradiating light of a light source 3 is decreased to get dim, whereas the propriety of soldering is more easily decided.

Title: Two-cycle engine
Inventor: KATO TAKASHI
IPC: F02B33/44
Filed: 1992-04-14
Abstract: PURPOSE:To prevent a mixture, with which a combustion chamber is once charged, from being sucked back into a crank chamber by providing a check valve device, which prevents a combustion mixture from reversely flowing in the crank chamber from the combustion chamber, in a scavenging passage. CONSTITUTION:A crankcase 20 is tightened to the lower part of a cylinder 14. A piston 22 is fitted reciprocatably slidably in the cylinder 14, to form a combustion chamber 24. A crank chamber 44, formed in the crankcase 20, communicates with a scavenging port 34 through a scavenging passage 46 of sinuate structure. A check valve device 48 is set up in the scavenging passage 46. In the check valve device 48, a mixture is permitted to flow in only a direction of the combustion chamber 24 from the crank chamber 44. The mixture is impeded from reversely flowing into the crank chamber 44 from the combustion chamber 24, and the mixture, with which the combustion chamber 24 is filled, is prevented from being sucked back to the crank chamber 44. Thus by increasing charging efficiency of the mixture in an engine, an output can be improved.

Title: Method for removing inorganic material and/or heavy organic material in solvent-purified coal
Inventor: MIFUJI YUTAKA
IPC: C10G1/00
Filed: 1985-06-03
Abstract: PURPOSE:To remove efficiently inorganic materials and/or heavy organic materials in solvent-purified coal, by bringing the solvent-purified coal into contact with a deasphalting solvent and mixing them to promote the growth of grains of the contained materials, precooling the resultant mixture to reduce the mutual adhesion of grains and subjecting the mixture to gravitational settling. CONSTITUTION:Inorganic materials and/or heavy organic materials in solvent- purified coal are removed by the gravitational settling method. A deasphalting solvent is brought into contact with the solvent-purified coal at a temperature as high as >=150 deg.C and mixed therewith to promote the growth of grains of inorganic materials and/or heavy organic materials. The resultant mixture is then precooled to <=150 deg.C to reduce the mutual adhesion of the grown grains, and the gravitational settling is carried out to remove the settled materials to the outside of the system. Thus, the inorganic materials and/or heavy organic materials in the solvent-purified coal are removed.

Title: Method for liquefying coal containing circulation system
Inventor: OKUMA OSAMU
IPC: C10G1/00
Filed: 1985-06-03
Abstract: PURPOSE:To improve the yield of a liquid hydrocarbon, by subjecting solvent- purified coal obtained by hydrogenation reaction of coal to a deashing step, removing only the ash, and circulating preasphaltene separated in the deasphalting step through the hydrogenation reaction. CONSTITUTION:For example, a slurrying agent and catalyst are added to coal dust, and the resultant mixture is brought to a high-temperature state. The mixture is then fed to the primary hydrogenation region, and high-pressure hydrogen is introduce thereinto to carry out the primary hdrogenation reaction at a high temperature under high pressure. The hydrogenated material is then distilled to separate naphtha and a solvent fraction as a product. The solvent- purified coal (CLB) is then subjected to a deashing step and deashed to prevent the accumulation of the ash in the system. After deashing, the CLB is fed to a deasphalting step to separate preasphaltene, which is circulated through the primary hydrogenation step to improve the yield of the distillate oil.

Abstract: PURPOSE:To simplify the assembling and to prevent the cross-talk discharge, by adhering a spacer having a flange section to the open end for inserting a U-shaped electrode then pressing it through a stopper board and fixing to a stem. CONSTITUTION:A spacer 5 having a flange section 5 composed of such as ceramic is adhered to one open end 3 of two U-shaped tubes 1 having the inner wall coated with phosphor subsistance 2. Then it is inserted into the notch section 9 of a stopper board 8 and placed over the electrode 13 on a stem 11 to press the flange section 5 of the spacer 6 against the flange section 5, while the stopper board 8 is secured to the stem 11 through a supporting rod 14 to secure between the U-shaped tube 1 and the stem 11. Thereafter an outer tube 16 is put on and sealed to the stem 11 to form a discharge lamp. Since the U-shaped tube 1 isn't required to be welded to the stem 11, the assembling is simplified while the oxidation of the electrode 13 is prevented to prevent the occurrence of the cross-talk discharge.

Title: Device of changing over multistage speed change gear of automobile
Inventor: HERUMUUTO REMUBORUTO
IPC: F16H61/32
Filed: 1978-09-29
Abstract: In a hydraulic transmission in which couplings and brake bands (servo-elements) control the gear ratio and are themselves engaged and disengaged in accordance with pressure applied thereto, a motor-driven slider is provided to connect a main pressure source directly to servo-elements which will remain engaged in the newly selected gear ratio. Solenoid operated valves are interposed between the main pressure source and a second intake port of the slider. Milled channels in the slider connect this second intake port to the servo-elements to be newly engaged during the gear shift. A known gear control unit operates the valves to control the rate of change of pressure increase at the second intake port to a selected value which will limit the jolt of the vehicle to a predetermined maximum jolt.

IPC: G01S13/58
Filed: 1980-08-29
Abstract: PURPOSE:To make it possible to measure the speed of a ball at the moment said ball is hit by means of a club, bat or the like, by utilizing the fact that when the fluctuation of the input frequency becomes small, the phase comparison output pulse width of a phase-locked loop (PLL) circuit becomes small. CONSTITUTION:A detection Doppler signal based on the frequency shift according to the moving speed of a moving object 1 such as a ball used in golf or baseball is applied to a PLL circuit 11 through a waveform shaping circuit 7. When the fact that the phase comparison output pulse width varying with the change of the input frequency of said circuit 11 has become less than a given value is detected by means of a synchronism detecting circuit 12 and a phase comparator 13, the synchronized state with the Doppler signal by means of the ball 1 having less speed change is judged to have been reached. Then, the start of the clock signal counting by means of a counter 8 is controlled. Accordingly, it is also possible to measure the speed of a ball at the moment it is hit by means of a club, bat or the like according to the Doppler signal from the ball separated therefrom the Doppler signal by means of the  club or bat.
