Title: Valve timing control device for engine
Inventor: OGURA AKIRA
IPC: F02D29/00
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To compensate influence of an external load to an engine to prevent errorneous learning when learning a reference position of a variable valve timing mechanism. SOLUTION: In this control device, in the case that an engine is in a stable state and feedback control with a most lag angle position as target valve timing VTTGT is executed, it is checked whether an air conditioner is turned on or not (S103, S104, S105). In the case of turning-on of the air conditioner, an air-conditioning correction value VTAC is added to actual valve timing VTB to correct the actual valve timing VTB (S106). Then, it is checked whether the engine is in a running range or not (S107). In the case of the running range, a running range correction value VTDRJ is added to the actual valve timing VTB to correct the actual valve timing VTB (S108).  By executing most lag angle learning by use of the corrected actual valve timing VTB, influence of an external load to the engine is compensated to prevent errorneous learning, and an offset to the most lag angle position is accurately reflected on a learning value to improve learning accuracy and to improve controllability of valve timing control.

Title: Image forming device
Inventor: FUJITA TAKESHI
IPC: G03G15/00
Filed: 1991-09-13
Abstract: PURPOSE: To effectively prevent the occurrence of a defect in driving caused by the toner stuck on a roller of a conveyance mechanism and the like by leaving the roller only inside an endless belt in overall length. CONSTITUTION: If the width of a conveyance belt 8 is taken as 11 , and the width of a roller 12 is taken as 12 , the widths of them are set as 11 <12 . If the width of the transferring area on an image bearing body 1a is taken as 13 , 11 >13 . Each length of rollers 11 and 76 which support and suspend the belt 8 is the same as that of the roller 12. Therefore, when the belt 8 is operated, both ends of the rollers 11, 12 and 76 supporting the belt 8 are completely covered with the peripheral edge section of the belt 8. Since all developing and transcribing processes are executed above the belt 8, toner will not drop and stick on both ends of the rollers by constituting a conveyance belt mechanism as described above. Therefore, the behavior of the belt 8 on the rollers such as vibration will not cause toner to enter between the surface of each roller and the rear face of the belt 8.

Abstract: PURPOSE:To enhance the degree of compression and to improve the channel using efficiency of a data communication system by deriving the number of same continuous character-strings, and bringing its number N to compression conversion to the combination of one piece or more of exponents and radixes, and a character. CONSTITUTION:A character-string extracting means 11 retrieves the continuous same character-strings from data 1, and for instance, derives the character A of character- strings 31a and 31b, and their numbers 125 and 1000. A compressing means 12 derives an exponent Xi and a radix Yi being the nearest to the number of characters by retrieving a power number table. For instance, in the case of the character-string 31b, the number 729 (the sixth power of three) being the nearest to 1000 is derived first, and subsequently, the number (the fourth power of four) being the nearest of the number 271 of the remainder is derived, and also, the number 9 (second power of three) being the nearest to the number 15 of the remainder is derived, the number 6 (the first power of six) of its remainder is derived, and a message train 32b combined with the character A is generated. In such a manner, data in which the same character- string is continued is compressed by a high compression degree, and the channel using efficiency can be improved.

Filed: 1988-10-18
Abstract: PURPOSE:To reduce operation cost and prevent the deterioration of the amount of retrieving heat by a method wherein gas is taken out of a duct communicated with a heat exchanger and shots are sent into a shot tank while gas after sending is returned to the initial duct. CONSTITUTION:When heat transfer tubes in a heat exchanger 6 are cleaned, gas, taken out of an outlet side duct 64, is sent into a transporting pipe-line 5 by a blower 1 and dust, adhered to the heat transfer tubes, is removed while dispersing the groups of shots into the heat exchanger 6 and dropping them naturally, then, the groups of shots are separated from the dust by a separator 3 after removing the dust and are returned into the transporting pipeline 5 again. Gas, which sent the groups of shots into a shot tank 7, is returned to the outlet side duct 64 through a returning pipeline 51. The gas for the transportation of the shots is the gas which flows through the heat exchanger 8 and, therefore, heating is not necessitated and the operation may be effected with a low cost. On the other hand, the amount of retrieving heat in the heat exchanger 6 will never be deteriorated any more.
