Title: Data transmission system
Inventor: OKUBO TAKAYUKI
IPC: H04L12/54
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To allow a server side to discriminate the end of reception of data immediately and correctly, and to eliminate the need for re-transmission from a transmitter even if an image is not normally outputted in the system that sends/receives data used for print such as image data or desk-top publishing DTP data. SOLUTION: An integrated program that automatically applies batch processing to a series of processing from file compression, transmission and file deletion when a transmission file and a destination server are selected is mounted on a controller 4 of a transmitter 1. When the transmission of data has been finished in the case of sending data, a transmission end flag file is sent succeedingly. When a reception folder 11 recognizes the transmission end flag file, the reception folder 11 discriminates that the reception of data is finished. Furthermore, upon receipt of a signal denoting a fact of normal image output from an image output device 14, the reception folder 11 moves the data to a 1st folder 20. Upon receipt of a signal denoting a fact that the image output cannot normally be made, the reception folder 11 moves the data to a 2nd folder 21.

Title: Internal-combustion engine with turbo charger
Inventor: KOMATSU HIROSHI
IPC: F02B37/22
Filed: 1985-01-17
Abstract: PURPOSE:To prevent torque drop in the range of starting the operation of a second turbo charger by substantially initially operating at least one variable capacity type of a plurality of turbo chargers. CONSTITUTION:An exhaust controlling valve 43 at the second turbo charger 9 side is closed in the low rotation and load of an engine, while the capacity of a first turbo charger 5 is minimized, i.e. the area of a turbine inlet path is minimized by a flap 39 of a variable capacity mechanism 33. Thus, exhaust is not flowed to a second turbine 11 and only the first turbo charger 5 is operated. And when discharge pressure, i.e. supercharging pressure reaches a predetermined value by a first compressor 21 as the engine load is increased, the flap 39 is opened to enlarge the capacity of the first turbo charger 5. Thereafter, when said capacity is maximized, an exhaust controlling valve 43 is opened and exhaust flows also into a second turbine 11, while the capacity of the first turbo charger 5 is lessened.

Filed: 1991-01-21
Abstract: PURPOSE:To offer the liquid crystal panel which makes a high-brightness, high- contrast image display and to the liquid crystal projection type television receiv er which uses the liquid crystal panel. CONSTITUTION:A light shield film 19 is formed at part of an additional capacitor and a light shield film 25 is formed as the top layer of a TFT. Light which is incident from the side of an opposite substrate 11 is scattered by high polymer dispersed liquid crystal 13 and the TFT is irradiated with a part of the light. The light shield film 25, however, is formed on the TFT, so the light does not reach the semiconductor film 21 of the TFT. Further, light which is reflected by a lens, etc., to return from the side of an array substrate 18 is cut off by the light shield film 19 and this light does not reach the semiconductor film 21 of the TFT either. No light excitation is therefore caused in the TFT, whose off characteristics can be held excellent.

Abstract: PURPOSE:To transfer deuterium in hydrogen to water, in carrying out exchange reaction, by a method wherein water is sprayed and a plurality of means for passing the formed mist like water and hydrogen through a catalyst layer in a concurrent downward flow are stacked. CONSTITUTION:In transfer of deuterium in hydrogen to water, water is supplied from a tower top and hydrogen from a tower bottom and said water is flowed downwardly onto a partition plate through a flooding pipe 4. To an ejector part 3, a nozzle 8 appropriately throttled so as to pass hydrogen and water vapor at a high speed is provided to promote the mixing of water and a hydrogen gas and, thereby, water is converted to mists. Water, hydrogen and water vapor are concurrently directed upwardly in a guide cylinder 6 and impinged to a flow passage deflector plate 7 to be reversed and passed through the catalyst layer 2 from an upper part to a lower part thereof. During this time, the exchange reaction is generated between hydrogen and water vapor as well as water vapor and water. Water with a large particle size is fallen onto the partition plate 5 and hydrogen, water vapor and mist like water are raised through a gap 9 and directed to an ejector part of the partition plate 5 of an upper stage. By repeating the above described process, deuterium is effectively transferred to water.
