Abstract: A method for automatically adjusting preload of a mandrel bearing and the apparatus thereof is disclosed. An inner separation ring and an outer separation ring are mounted between two bevel ball bearings inside a bearing seat. A heat insulation layer is formed on the outer separation ring and a helical groove is formed in an outside cylindrical surface thereof. Water flow-in and flow-out channels are defined in the bearing seat. The ends of the channels are respectively connected to the outlet end and inlet end of the groove of outer separation ring. The other ends of the channels are connected to a temperature controller located outside the mandrel. A thermometer is mounted inside the bearing seat at a location corresponding to outer ring of the bearings for measuring the temperature of the outer ring which is fed back to a controller. After performing calculation, the controller controls the temperature controller to change the temperature of the liquid flowing into the outer separation ring in order to control the length change of the outer separation ring which withdraws when cooled down and expands when heated up, and thus providing a simple and low cost design for automatically adjusting the preload of the bearing.

Granted: 2005-12-11
Abstract: There is provided a method for obtaining a target organic compound such as an alkyladamantyl ester efficiently by purifying a crude organic compound which contains, as impurities, sublimable materials which start to sublime at temperatures lower than a boiling point of the target organic compound by use of such a simple method as distillation during its production process, without being adversely affected by adherence of the sublimable materials. The distillation is carried out in the presence of a compound having a boiling point which is lower than a boiling point of the target organic compound, e.g., a carbonyl-group-containing compound. For example, 2-methyl-2-adamantyl methacrylate (boiling point: 92 DEG C/0.3 mmHg) containing sublimable impurities such as adamantane (sublimation starting temperature: room temperature or lower) is distilled in the presence of 1,3-dimethyl-2-imidazolidinone (boiling point: 225 DEG C).

Title: Irrigation use dripping pipe with integral formation construction
Inventor: SHIU TZAU-HUEI
IPC: A01G25/02
Filed: 2001-03-05
Granted: 2001-11-11
Abstract: An irrigation use dripping pipe with an integral formation construction is made by an integral formation device. An integral extrusion mold is used to directly extrude a pipe having a main conduit, a lamination pipe wall and a fiber core layer. The lamination pipe wall is directly extruded inside the main conduit. The fiber core layer is formed between the main conduit and the lamination pipe wall. When winding the formed pipe, a laser projector projects a projection beam in a fixed interval on the outer edge of the main conduit to drill an outlet hole. Meanwhile, another laser projector projects a light beam through the formation extrusion mold and onto a reflection mirror, reflecting on a focusing mirror to drill an inlet hole. Thus, only one formation process is used to produce an irrigation use dripping pipe having a construction comprising a main conduit, a lamination pipe wall, a fiber core layer, an inlet hole and an outlet hole, thereby achieving the objective of reducing the production process and working hours, as well as the production costs.

Granted: 2004-06-11
Abstract: A magnetic recording disk drive with a magnetoresistive (MR) read head and a control unit comprising an operating pressure logic function that is responsive to a thermoresistive signal contained in the feedback signal from the MR read head. The thermal conductivity of the air inside of the hard disk drive is effected by the air pressure. Fluctuation in the thermal conductance from the MR read head to its surroundings inside of the hard drive affects the temperature of the MR head, thus affecting the thermoresistivity of the MR read head. Based on a thermoresistive signal, the temperature of the head may be determined, which in turn is applied to determine the pressure, based on a predetermined relationship between the MR read head temperature, internal pressure, and internal operating temperature.

The temperature deviation of the hot plate is inhibited through the closed-loop feedback control. In addition, the end sides of the heater 16A to 16F are fixed to a hot plate body 13 via flanges with sealing packings 20A to 20F. The other ends are inserted into bottom holes 24A to 24F of support members 23A to 23F press-fitted in the other end sides of the holes 14A to 14F, and set so that the thermal expansion differences in between and gaps of a radial direction of substantially 0.2 to 0.4 mm can be formed.
