Patent JP-S60206928-A (JP)
Title: Internal combustion engine
Inventor: DAN MERITSUTO
IPC: F02B41/00
Filed: 1985-03-08
Abstract: An internal combustion engine has two cylinders (12, 14) interconnected at their head ends by a combustion chamber (20) which contains a catalyst (22). The cylinders have respective pistons (16, 18) reciprocable towards and way from the combustion chamber (20) and arranged to perform together the induction, compression, expansion and exhaust strokes. Air only or the like is freely inducted into one cylinder (12) while fuel or a fuel/air mixture is metered and inducted into the other cylinder (14) during the induction stroke. The catalyst is of a type which effects a chemical reaction to initiate combustion at a relatively low temperature so that when the fuel/air mix contacts the catalyst at the required temperature ignition takes place. The crank shaft angular phase difference between the pistons (16, 18) is controlled during operation so that the air in the first cylinder (12) is at a higher pressure than the fuel or fuel/air mixture in the other cylinder (14) during compression strokes and is forced through the catalyst, preventing contact of the fuel or fuel/air mixture in the second cylinder (14) with the catalyst until ignition is required when the first piston is in the vicinity of its top dead centre. Since it is the movement of the pistons themselves which control the ignition timing the latter is not dependent on the timed induction of the fuel and an external ignition circuit is also not required. This provides a much simplified form of engine.

Title: Removal of dissolved silica
Inventor: ICHIJO TOSHITAKA
IPC: C02F1/42
Filed: 1989-03-01
Abstract: PURPOSE:To simply and efficiently remove silica by treating raw water with an H<+>-type weak acidic cation exchange resin to form alkali removed soft water and, after adding caustic soda to the soft water, treating said soft water with a reverse osmosis membrane while activating a silica salt simultaneously by an appropriate method. CONSTITUTION:The alkali component and hardness component in raw water 1 are removed by an alkali removing water softening tower packed with a weak acidic cation exchange resin regenerated into an H<+> type. Since a large amount of decomposed carbon dioxide is contained in alkali removed soft water 4, said carbon dioxide is removed by countercurrent air blow in a carbon dioxide removing tower 5. Further, excessive acid is neutralized with caustic soda to make the soft water weak alkaline. A dissolved silica salt is activated in an ion activating apparatus 9 and silica is removed by a reverse osmosis silica removing cylinder 11. This method is economical because flocculation treatment is unnecessary and the removal ratio of silica is high and certain.

CONSTITUTION:A key is turned, and a detector circuit 17 outputs H by low engine temperature or a comparator circuit 8 outputs H by low temperature of glow plugs 1 themselves, if an engine is in a stop state, a transistor 27 and relay 26 are turned on to close a self holding switch 21, and the contact of a main relay 3 is closed becuase of H output of the comparator circuit 8, then the glow plugs 1 rapidly increase temperature even if an engine key switch 20 is not closed. If the glow plug reaches prescribed temperature, the output of the comparator circuit 8 becomes L, and the transistor 27 is turned off to open the self holding switch 21. Though the glow plug is cooled, power is not fed to the comparator circuit 8 and its peripheral circuits when the engine is not intended to start, then the main relay 3 and subrelay 4 are not operated.

Title: Method for setting paper supply timing for electrophotographic copying machine
Inventor: WAKIKAIDOU TAKAHIRO
IPC: G03G21/14
Filed: 1991-03-12
Abstract: PURPOSE:To easily align leading edge of a paper with the tip of a toner image by setting the timing of paper supply so that the leading edge of the paper is delayed with respect to the tip of the toner images as much as dislocation quantity from the reference position of an image forming position. CONSTITUTION:A control part MC controls a resist clutch CL and the various kinds of load LD by receiving an output from a keyboard KB and a sensor SR for detecting the leading edge of an original. Then, the timing that the leading edge of the paper P is aligned with the tip of the toner image formed on a photosensitive drum 9 is adjusted by the timing that the clutch CL is turned on by the operation of the keyboard KB. When the image forming position on the drum 9 is dislocated from the reference position in the rotating direction of the drum 9 by (alpha) by the optical magnification of the image, the timing is set so that the leading edge of the paper P is delayed from the tip of the toner image by (alpha). Thus, however the magnification is changed, the leading edge of the paper p can be aligned with the tip of the toner image within an allowable range.

Title: Molding method for calcium phosphate glass
Inventor: KOBAYASHI SHIGEYOSHI
IPC: C03B19/04
Filed: 1985-03-12
Abstract: PURPOSE:To prevent reaction between a mold material and molten glass and to obtain a molded body contg. no foam or foreign matter with high dimensional accuracy in the process for casting melt of calcium phosphate glass in a mold and cooling, by specifying the mold material. CONSTITUTION:Melt contg. >=90wt% calcium phosphate is casted in a mold consisting of a mold material contg. 1-90wt% BN and solidified by cooling. When the content of BN is <1wt%, the effect for reducing wettability by the mold material is insufficient. If the content of BN is >90wt%, the strength of the mold is decreased and the mold is easily broken during molding due to the insufficiency of the proportion of binder. Removal of BN from the mold is also caused during molding and removed BN is liable to mix with the glass. The kind of the binder for the mold material is not limited, but phosphate, silicate and gypsum are preferred because of providing a mold having high strength and resulting desirable operability such as requirement of appropriate hardening time, etc.

Title: Correcting lens for exposing fluorescent screen of color cathode-ray tube
Inventor: KUKI KOJI
IPC: H01J9/227
Filed: 1991-03-13
Abstract: PURPOSE:To prevent nonuniformity and discontinuity of luminance on a back surface of a panel to be irradiated even if a correcting lens consisted of a discontinuous lens block assembly is used by forming grooves on the surface along a boundary between adjacent lens blocks. CONSTITUTION:Grooves are formed on a correcting lens for exposing a fluorescent screen of a color cathode-ray tube consisted of a discontinuous lens block assembly along a boundary between adjacent lens blocks. V-shaped grooves having a top angle of 90 deg. are formed in the boundary between the lens blocks. The lens block is formed in 8mmX8mm, and 475 blocks in total of 19 columns by 25 rows constitute a multiple lens. Burr is generated when a discontinuous lens is processed by pressing. A step portion in the boundary between the lens blocks is cut by NC milling work. A milling depth is determined according to a step amount between the lens blocks and an incident angle different by the position on the lens. Consequently, it is possible to alleviate nonuniformity of light intensity due to the step portion between the lens blocks.
