Patent JP-S58185954-A (JP)
Title: Internal-combustion engine
Inventor: KOBAYASHI AKIHIRO
IPC: F02D17/02
Filed: 1982-04-26
Abstract: PURPOSE:To reduce a pumping loss in cylinders at the stopping side as well as to realize a distinct improvement in fuel consumption, by intercepting the supply of suction air into cylinders at the stopping side at the time of operating a partial cylinder, while constituting an engine structure so capable of leading the atmospheric pressure inside, in case of a cylinder number control engine. CONSTITUTION:During high-load running, a cutoff valve 6 is opened while a breather valve 9 is closed, and in this condition, the air being fed through a suction passage 4 is distributed to all branch passages 4a-4d and simultaneously operates all fuel injection valves 5a-5d, operating all cylinders 2a-2d. On the other hand, during light-load running, fuel injection valves 5b and 5c are stopped by action of a fuel control mechanism whereby the cutoff valve 6 is closed and the breather valve 9 is opened by means of a valve control mechanism. If so, it means that cylinders 2b and 2c at the stopping side are supplied with such air as being substantially equivalent to the atmospheric pressure via an atmospheric passage 7, so that a pumping loss in these cylinders 2b and 2c can be reduced.

Title: Superimposed transmission system
Inventor: ARITOME HIDEKI
IPC: H04J3/16
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent the 'head break' of a voice that occurs right after a high/low quality switching operation by forming a superimposed transmission system where the sound signals of a low quality section are compressed and the image signals are superimposed on the blank parts produced by compression of the sound signals to synthesize the transmission data and to transmit them. SOLUTION: An image input part 12 inputs the images. When a moving image is inputted, an image pickup device like a camera, etc., is used. Then an image reading device like a scanner, etc., is used for a static image. A sound signal memory part 15 temporarily stores the digital sound signal received from a sound signal encoding part 13 and then outputs the sound signal to a multiplexing part 18. At the same time, the part 15 delays the sound data by a time that is needed for a sound signal decision part 16 to detect the high/ low quality sections. Thus the synchronization is secured between the sound data which are read by the part 18 and the identification signal sent from the part 16. As a result, the 'head break' of a voice occurring right after a high/low quality switching operation can be prevented.

Title: Fringe scan shearing interference measuring instrument
Inventor: KANOU TOSHIO
IPC: G01B9/02
Filed: 1984-04-06
Abstract: PURPOSE:To measure an objective surface with large asphericality without increasing the size of each corner cube (CC) by causing information light to strike a beam splitter through a relay lens and then allowing measurement light and reference light to enter respective CCs. CONSTITUTION:The convergent relay lens 38 is provided between a beam splitter 18 which splits light into illumination light traveling to a converter lens 20 and information light and a beam splitter 22 which separates measurement light and reference light from each other. The measurement light and reference light are incident on an image forming lens 36 through CCs 24 and 26 and the splitter 22 to form images on an area sensor 34. A lens 38 functions to make the information light incident on the splitter 22 as convergent luminous flux. Therefore, divergence is suppressed by the lens 38 and the light is made incident on the CCs 24 and 26 even the objective surface is aspherical and the information light from the lens 20 is divergent, so even an objective surface having larger asphericality is measured.

Title: Anticorrosive for metal
Inventor: KAWASAKI YOSHINARI
IPC: C23F11/14
Filed: 1981-05-07
Abstract: PURPOSE:To enhance the corrosion preventing effect of the resulting anticorrosive for metal and to remove a fear for environmental pollution by adding polymaleic acid or a salt thereof and a sarosine compound or a salt thereof as effective components. CONSTITUTION:This anticorrosive for metal contains polymaleic acid or a salt thereof and a sarosine compound or a salt thereof represented by formulaI (where R is 8-22 C hydrocarbon) as effective components. This anticorrosive is used to prevent the corrosion of metal contacting with water, e.g., ferrous metal. Since this anticorrosive contains both of said components, the formation of scale is extremely inhibited, and a superior corrosion preventing effect is shown by this anticorrosive used ina smaller amount than the amount of an anticorrosive contg. only a sarcosine compound. By combining said components with aliphatic hydroxycarboxylic acid, the corrosion preventing effect can be enhanced furthermore.

     CONSTITUTION: Under atmospheric conditions, a substituted 5-nitrosopyrimidine is subjected to a reductive formylation to obtain a 5-formylaminopyrimidine of the formula (wherein R 1  to R 3  are each H, OH, SH, NH 2 , an alkylamino, halogen, O-alkyl, S-alkyl, 1-4C alkyl or aryl). This reductive formylation is carried out in the presence of a catalyst based on a noble metal (particularly preferred being Pd or Pt) and formic acid and a salt thereof. It is suitable to carry out the reaction at 50-200°C. It is preferred that the catalyst is separated by filtration from the reaction mixture and the product is successively crystallized from the solution by condensation and/or cooling. Particularly, it is suitable that an NaOH solution is added to the reaction mixture until the product has been completely dissolved and subsequently, the catalyst is separated by filtration to successively re-precipitate the formylamino compound with the use of an acid.
