Q:Man, can you send me some national standards? Mainly for hydraulic use
Here you are, some European companies, but you need to download them on the Baidu Library
Q:How to save money on some bills!?
To clean the small rollers on a normal mouse that has the small rubber ball in it, do these steps. You will need a sturdy fingernail or cotton-swab or a few toothpicks or a single tooth from a plastic fork, and some tissues or cloth. Turn the cover counter clockwise (like backward in time) to unscrew and release the small circular cover. It may be tough and may take a lot of pressure. Keep track of this cover and the ball. Turn the mouse over into one hand and slap it into the hand if the cover and the ball do not come out easily. Again, this is for a normal wheel-mouse which is actually a wheels-and-ball mouse you will see this now, if you have the ball out. There are to rollers or wheels that need to be cleaned up if any crud gunk dirt stuff is on either one. There is a third roller too, or it may be a thin plastic piece like a short thin plastic toothpick. The two wheels and the roller all need to be cleaned. Clean these each roller and wheel WITHOUT REMOVING and WITHOUT BREAKING until any stuff that had been stuck on the contact surfaces is cleaned off. Now the ball can be put back into the mouse and the cover can be put back onto the bottom of the mouse to hold the ball inside the mouse. It is a messy and delicate task. This is why at work you may hear of people being told to buy a new mouse, or the I.T. department brings a new mouse and likely throws away the old mouse.
