Filed: 1986-10-14
Abstract: PURPOSE:To make the passing flow proportional to the section area of each orifice, by making the sections in the flow direction of the orifices which regulate the flow of the fluid passing through the plural valve seats, in the similar figures. CONSTITUTION:The sections square to the flow direction of a fluid of orifices 7a, 7b, 7c, and 7d of valve seats 6 are all circular, and the ratio of their areas is 1:2:4:8, the converted ratio of their diameters being about 1:1.4:2:2.8. On the other hand, the lengths of the orifices7a, 7b, 7c, and 7d are set mD which are proportional to the diameters D of the orifices 7a, 7b, 7c, and 7d. Since the length of the orifice of each element valve is proportional to its diameter, the difference between the pressure losses of the passing fluid through a small bore orifice and that through a large bore orifice is little.

IPC: F16H15/52
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To supply the sufficient quantity as required of a lubricant regardless of its change gear ratio at all times. SOLUTION: The driving force of an engine E is transmitted to driving wheels by a chain 72 by way of a continuously variable transmission T and an auxiliary transmission R. Oil discharged out of an oil pump 82 provided for the shaft end of the speed reduction shaft 69 of the auxiliary transmission R lubricates a speed change rotating member 39 through an oil flowway in the inside of the transmission main shaft 21 of the continuously variable transmission T. The number of revolution of the speed change rotating member 39 is increased at the side of a TOP ratio so as to allow the necessary quantity of lubricant to be thereby increased, and since the number of revolution of the oil pump 82 driven by the speed reduction shaft 69 of the auxiliary transmission R is also increased, lubricating performance at the TOP side can thereby be sufficiently secured.  And furthermore, oil at the side of a LOW ratio side is prevented from being excessively fed, and the quantity of power consumption by the oil pump 82 can thereby be reduced.

Title: High-speed printing system
Inventor: KUBOTA KOJI
IPC: B41J2/255
Filed: 1987-09-29
Abstract: PURPOSE:To enable a high-speed bit-shifting process for printing data, thereby realize high-speed printing and enhance the efficiency of a printer system, by providing a DMA controller which outputs a shifting signal under the control of a processor and controls direct transfer of the printing data between a memory and a buffer memory. CONSTITUTION:By a DMA controller 5 controlled by a processor, printing data for each recording element such as a nozzle collectively stored into a memory in the order of printing is transferred directly to a buffer memory 4 through an array-converting circuit 3. In this case, a shifting signal according to the interval of the recording elements is outputted to the circuit 3, thereby performing appropriate bit-shifting for the printing data transferred. The bit- shifted printing data transferred to the buffer memory 4 is outputted to the recording elements, whereby the printing data are printed. Thus, the bit-shifting process can be performed at a much higher speed, as compared with a conventional program control system in which the process is carried out through a processor. Therefore, high-speed printing by the recording elements can be realized, and the efficiency of a printer system can be markedly enhanced.
