Method of controlling continuously variable transmission and control system

An oil pressure-learning method which enables an oil pressure control system that controls line pressure and belt clamping pressure by oil pressure actuators independently of each other, to accurately control both the line pressure and the belt clamping pressure. The oil pressure-learning method is applied to an oil pressure control system provided with a line pressure control solenoid for controlling a line pressure control valve, and a belt clamping pressure control solenoid for controlling a belt clamping pressure control valve. A belt clamping pressure command value that is outputted to the belt clamping pressure control solenoid as a control command value of belt clamping pressure, and a line pressure command value that is outputted to the line pressure control solenoid as a control command value of line pressure are learned in advance. This enables the oil pressure control system to control both the line pressure and the belt clamping pressure with accuracy.

Synchronous motor drive unit and a driving method thereof

A rotary sensor that outputs two analog signals, such as one sine wave and one cosine wave and has multiple periods within one period of the electrical angle of a motor is employed. The motor is energized at each position for a specified length of time upon its startup by using multiple electrical angles corresponding to the multiple candidate absolute angles obtained from the rotary sensor signal as the initial position of the motor, and the electrical angle at which the motor acceleration becomes maximum is determined as the absolute angle. While the motor drive is in operation, on the other hand, the phase difference Δθ between the phase of the motor at the counter electromotive voltage and the control phase is directly computed from the parameters of the motor, sensed current, voltage command and angle speed so as to correct the shifted position.

Method for isolating cell-type specific mrnas

The invention provides methods for isolating cell-type specific mRNAs by selectively isolating ribosomes or proteins that bind mRNA in a cell type specific manner, and, thereby, the mRNA bound to the ribosomes or proteins that bind mRNA. Ribosomes, which are riboprotein complexes, bind mRNA that is being actively translated in cells. According to the methods of the invention, cells are engineered to express a molecularly tagged ribosomal protein or protein that binds mRNA by introducing into the cell a nucleic acid comprising a nucleotide sequence encoding a ribosomal protein or protein that binds mRNA fused to a nucleotide sequence encoding a peptide tag. The tagged ribosome or mRNA binding protein can then be isolated, along with the mRNA bound to the tagged ribosome or mRNA binding protein, and the mRNA isolated and further used for gene expression analysis. The methods of the invention facilitate the analysis and quantification of gene expression in the selected cell type present within a heterogeneous cell mixture, without the need to isolate the cells of that cell type as a preliminary step.

A detachable, heat resistant, flexible button protector protects against button degradation during laundering, dry-cleaning or hot ironing operations. The protector has an enclosure for forming a cavity surrounding at least one button. A slit in the side of the enclosure accommodates insertion of the button into the cavity. Button degradation is prevented by sealing the enclosure to minimize penetration of cleaning fluids during insertion and residence of the button within the cavity. The protector shields the button from corrosive laundering and dry-cleaning chemicals, while allowing entry of chemicals that wash the fabric on which the button is sewn. It is strong enough to withstand compressive force and shock impact produced by laundering machinery. Chipping and chemical degradation of buttons is virtually eliminated. Laundering, dry-cleaning and ironing operations are carried out economically in an efficient, reliable manner.
