| 20110185569 | METHOD AND DEVICE FOR ADJUSTING VALVE CLEARANCE - A method for adjusting a valve clearance in a cylinder head using a rocker arm of a support point adjustable type. In the method, an adjustment screw is rotated in one direction until a camshaft comes in contact with a cam shaft contact section to make the amount of valve opening zero, then further rotated until the valve is released with a certain valve opening amount, and after that, rotated in a reverse direction by a certain rotation angle and accordingly loosened until a desired valve clearance value is obtained. In the process above, the method determines a first rotation angle of the adjustment screw necessary for the adjustment screw to move from a position where the valve is released with the certain valve opening amount to a position where the camshaft comes in contact with the camshaft contact section. Then, the method determines a second rotation angle of the adjustment screw necessary for the adjustment screw to move from the position where the camshaft comes in contact with the camshaft contact section to a position where the desired valve clearance value can be obtained. After that, the method rotates the adjustment screw in the reverse direction by a given rotation angle that is a sum of the first and second rotation angles. | 08-04-2011 |

| 20100121479 | DECOMPRESSING TYPE HEATER, ITS HEATING METHOD, AND ELECTRONIC PRODUCT MANUFACTURING METHOD - An object is heated to a preheating temperature in an atmosphere of a reducing gas under the atmospheric pressure while adjusting the setting of the emissivity of a non-contact temperature measuring part and regulating the temperature of the object according to the measured value measured by a contact temperature measuring part. The pressure of the atmosphere is reduced. The object is further heated to a heating temperature under a lowered pressure while regulating the temperature of the object according to the measured value measured by the non-contact temperature measuring part whose setting of the emissivity is adjusted during the heating process to the preheating temperature. The pressure of the atmosphere is increased back to the atmospheric pressure while maintaining the heating temperature of the object. The temperature of the object is decreased under the atmospheric pressure. With this, in the process of heating an object under a lowered pressure, the actual temperature of the object is managed over the whole steps, and the object can be most suitably heated according to the actual temperature. | 05-13-2010 |
