Title: Burning device
Inventor: NISHIKAWA TAKASHI
IPC: F23D11/40
Filed: 1985-10-29
Abstract: PURPOSE:To form uniform fire flames at the whole flame holes placed at the circumferential wall of a burner head and eliminate ignited white smoke at the same time by installing a perforated plate and a mixing cylinder in a burner head in such a way that the plate has a non-hole part facing a mixed gas inflow hole and the cylinder has an opening facing the non-hole part of the plate and bypass holes facing an igniting electrode. CONSTITUTION:Premixed gas flowing into a mixing cylinder 20 collides with the non-hole part of a perforated plate 21 to disperse around the non-hole part and passes through the plate 21. A part of the gas is spouted from flame holes 14a near an igniting electrode through bypass holes 20b and the most part of the gas joins from the circumferential part of the cylinder 20 into a central hole 20a and flows into a burner head 13 to spout from flame holes 14 at the cicumferential wall. Therefore, mixing of vaporized fuel and burning air is extremely satisfactory. And, as premixed gas flowing into flame holes 14a for ignition arrives at the flame holes earlier in time than premixed gas flowing from the other flame holes 14, white smoke is not generated.

Title: Image forming device
Inventor: OSAKI MASAMITSU
IPC: G03G15/16
Filed: 1997-08-24
Abstract: PROBLEM TO BE SOLVED: To suppress the surface staining of toner on the surface of an intermediate transfer body and to enhance image quality by using a cleaning blade abutting on the surface of the intermediate transfer body in a trailing direction as a cleaning member. SOLUTION: The trailing system cleaning blade 17 is used. The blade 17 is set so that the fluctuation center thereof is positioned on a more upstream side in the moving direction of the surface of an intermediate transfer belt 5 than the abutting part of the blade 17 with respect to the belt 5. In such a case, when the tip edge part of the blade 17 abuts on the surface of the belt 5, such anxiety that the tip part is inverted because it is wound in the surface of the belt 5 is not caused. Thus, since toner separated from the surface of the blade 17 is attached to the non-image area on a more downstream side than the image area of the surface of the belt 5, the surface staining is prevented from occurring when the next toner is primarily transferred in the image area.

Title: Dynamic picture reproducing device
Inventor: KIKUCHI RYOICHI
IPC: H04N19/423
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To provide a dynamic picture reproducing device enhanced in responsiveness and capable of quickly executing the operation instruction entered by the user in the period when the compression-coded dynamic picture is decoded and reproduced in a slow mode without increasing the cost of the device. SOLUTION: A CPU 10 sets a variable denoting a storage capacity of data to an input buffer at slow reproduction smaller than that at usual reproduction. In the case of slow reproduction, compressed dynamic picture data from a recording medium are transferred to the input buffer, an MPEG decoder 14 decodes the transferred data and the dynamic picture is slowly reproduced. In this case, when a revision instruction of, e.g. show reproduction speed is entered from a user interface 19, the CPU 10 conducts control corresponding to the instruction after the input buffer 13 is empty, that is, all data in the input buffer 13 are given to the MPEG decoder 14.  Since the maximum capacity of data stored in the input buffer 13 has been set smaller in this case, the input buffer 13 is empty within a short time and the reproduction speed switching or the like at slow reproduction is controlled with an excellent response.

Inventor: SUZUKI KOICHI
IPC: G06F12/08
Filed: 1990-09-12
Abstract: PURPOSE:To prevent the deterioration of performance of the whole system by executing the page substitution in accordance with the number of times of accesses at every page held in a memory, when there is no page to be accessed in a main storage device. CONSTITUTION:The number of times of accesses at every page of a main storage is held in an R memory 23, and when the number of times of accesses of the main storage counted by a counter 11 becomes a prescribed number of times, the contents of this R memory 23 is subjected to decrement by an arithmetic circuit 27. Accordingly, the present use frequency of accesses to the main storage at every page is reflected on the contents of the R memory 23, therefore, in the case a processor tries to access data of an address of an extension storage which does not exist on the main storage, even if the contents of the R memory 23 are in an all page use state, the data can be transferred to the page whose using frequency is the lowest at present from a secondary storage by the contents of the R memory 23. In such a way, deterioration of performance of the whole system is prevented.

Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To reduce an equipment cost and running cost by forming a condenser of a front stage as a surface condensation type heat exchanger and forming a condenser of a rear stage as a jet ejector condenser in common use as an ejection and a condenser. SOLUTION: The first condenser of the front stage is formed as the surface condensation type heat exchanger 4 and the second condenser of the rear stage as the jet ejector condenser in common use as an ejector and a condenser constituting part of a momentum moving type vacuum pump which functions even if a condensed water temp. attains 50 to 70 deg.C. As a result, a manufacturing cost is reduced without using two units of heat exchangers. Since a high condensed water temp. suffices, the use of an inexpensive cooling tower making it possible to obtain a large volume of circulating water is eventually made possible and the initial running cost is reduced. Further, the intrusion of air bubbles into the condensed water does not occur and high condensation efficiency is obtd.
