This disclosure provides systems, methods, and apparatuses, for producing an electrical apparatus. In one aspect of the disclosure, a method includes identifying a first electrical apparatus including a first winding configured to receive a first voltage, the first winding including a first electrical coil and a second coil coupled in series. The method also includes determining, based on a reduction rate, one or more characteristics of a second electrical apparatus including a second winding configured to receive the first voltage, the second winding including a third electrical coil and a fourth coil coupled in parallel. Each of the first coil and the second coil including a first number of turns and each of the third coil and the fourth coil including a second number of turns. The reduction rate is associated with a ratio based on a reducing number of turns and the first number of turns.

Reduction rate and voltage multiple for parallel circuit

The present disclosure relates to a frequency sensitive type shock absorber configured to generate a soft damping force using one dividing disk to change the damping force on the basis of a traveling speed of a vehicle and a state of a road surface, improve ride comfort and steering stability, and decrease a manufacturing cost.

Frequency sensitive type shock absorber

Provided is a shock absorber for a railway vehicle, in which an eccentric disk is disposed on a rear surface of a valve disk to set a supporting force for an initial opening position of the valve disk to a relatively low value and continuously open the valve disk from the initial opening position of the valve disk during strokes, thereby controlling a damping force in a low speed section and realizing a soft damping force.

Shock absorber for railway vehicle

The present invention relates to a body valve assembly for a shock absorber, which is capable of improving ride comfort by improving the degree of freedom of the adjustment in damping force and preventing the damping force from being rapidly changed.

Body valve assembly for shock absorber

Provided are picolinamide and pyrimidine-4-carboxamide compounds, a method for preparing the same, a pharmaceutical composition containing the same, and a medical use using the compound as an agent for preventing, regulating, and treating diseases related to regulation of glucocorticoids by using selective inhibitory activity of the compound for an 11&#x3b2;-HSD1 enzyme. The picolinamide and pyrimidine-4-carboxamide compounds of the present invention are selective inhibitors of human-derived 11&#x3b2;-HSD1 enzymes, and are useful in an agent for preventing, regulating, and treating diseases related to glucocorticoid regulation in which human-derived 11&#x3b2;-HSD1 enzymes are involved, for example, metabolic syndromes such as, type 1 and type 2 diabetes, diabetes later complications, latent autoimmune diabetes adult (LADA), insulin tolerance syndromes, obesity, impaired glucose tolerance (IGT), impaired fasting glucose (IFG), damaged glucose tolerance, dyslipidemia, atherosclerosis, hypertension, etc.

The present invention relates to a stable pharmaceutical composition for injection containing docetaxel and a method of preparing the same. More particularly, the present invention relates to a pharmaceutical composition for injection containing docetaxel having better storage stability than conventional medications, which is prepared by dissolving docetaxel, a water-insoluble compound, in distilled water after mixing it with cyclodextrin (CD) and a water-soluble polymer such as hydroxypropyl methylcellulose (HPMC), polyethylene glycol (PEG) or polyvinylpyrrolidone (PVP) and lyophilizing the mixture, and a method of preparing the same.

Stable pharmaceutical composition containing docetaxel and a method of manufacturing the same

Disclosed herein is a shock absorber for damping vibration transmitted to a vehicle according to a road state. The shock absorber includes a cylinder and a piston valve disposed within the cylinder and connected to a piston rod. The piston rod includes a hollow chamber formed within the piston rod, a floating piston disposed within the hollow chamber to move up and down and to divide the hollow chamber into upper and lower chambers, and a moving mechanism formed in the hollow chamber to move an operating fluid to upper and lower portions of the floating piston. The shock absorber can change a damping force according to a displacement of the piston rod, thereby improving driving comfort and stability of the vehicle.

Shock absorber

A self leveling shock absorber includes a base shell, an inner tube in the base shell, having a low pressure chamber between the shell and the inner tube, a piston rod in the inner tube and having a hollow portion with an upper portion closed, a piston valve coupled to the piston rod, dividing space in the inner tube into rebound and compression chambers. An outer tube installed to a lower portion of the inner tube having a high pressure chamber and a gas chamber between the shell and the outer tube. A diaphragm divides the high pressure chamber from the gas chamber. A body valve is installed to a lower end of the inner tube to control flow of fluid between the low pressure chamber and the high pressure chamber, and a pump rod is provided having a hollow portion and one end installed to the body valve and another end inserted into the hollow portion of the piston rod. A relief valve is positioned under the pump rod.
