Abstract: An optical information storage medium includes at least one substrate, at least one recording layer, and at least one thermal diffusing layer. In this case, the recording layer is disposed over the substrate, and the thermal diffusing layer is disposed at one side of the recording layer. If the recording layer is composed of an endothermic-exothermic mixed material, the thermal conductivity coefficient of the thermal diffusing layer is approximately smaller than 10 W/m-K. If the recording layer is composed of an exothermic material, the thermal conductivity coefficient of the thermal diffusing layer is approximately greater than 10 W/m-K.

Abstract: A method of updating parameters of an embedded system through an object push profile (OPP) is used to update parameters of a Bluetooth-enabled device that does not have a keyboard. By using the OPP, a vCard is sent from an initiator to the embedded system, and a resolver extracts contents of fields of the vCard and stores the contents in a storage module. The contents are used to set a device name and a password of the Bluetooth device.

Abstract: Disclosed is an improved jack structure, includes a main body, a cover, two protective covers, a lock piece and a conductive piece. When an object is inserted into a single one of insertion holes each corresponding to one of the protective covers on the main body, a corresponding one of the protective covers is pushed to move. A protrusion of the pushed protective cover then pushes an urging portion of the lock piece and the urging portion is stopped by the other one of the protective covers. Therefore, the improved jack structure can be prevented from being inserted with an acute object and thus from occurrence of electric shock.

In addition, the pump has a simple apparatus with a lighter weight and smaller volume, thereby decreasing the space of operation and storage.

Abstract: An ion sening circuit comprises a bridge sensing circuit and a differential amplifying circuit. The bridge sensing circuit detects the ion concentration of the solution in the operation mode of constant voltage and constant current. The differential amplifying circuit compares the output of the bridge sensing circuit and a floating reference voltage, thereby the delivered voltage to the bridge sensing circuit, such that the opeation mode of constant voltage and constant current is formed accordingly. The main features of the disclosed circuit are that it grounds the reference electrode and floats the source terminal. The drawbacks of not being manufactured with intergrated circuits by CMOS technology and low benefits when applied to sensor arrays are avoided by the disclosed circuit.

Abstract: A cruciform pump comprises a casing, a positioning round disk in the casing; a driven rotary disk; and two sliding blocks. A center of the positioning round disk is arranged corresponding to a center of the casing, and has a cruciform sliding groove. The driven rotary disk is eccentrically installed on the positioning round disk. One rotary shaft at one surface of the rotary disk protrudes out of the casing. The two sliding blocks are installed in the cruciform sliding groove. Each block is conformed to the sliding groove, so that the positioning round disk is driven by the sliding blocks. When the driven rotary disk rotates through two circles, the positioning round disk only rotates through one circle. During rotation, the two sliding blocks move along the cruciform sliding groove; then, one side of the sliding block presses fluid flowing out, and another side thereof will suck fluid into the sliding groove.

Abstract: Within an apparatus for storing a liquid, there is first included a storage tank. The storage tank has formed integral thereto and in fluid communication therewith a liquid inlet port and a liquid outlet port. The storage tank also has formed integral thereto and in fluid communication therewith a gas inlet port and a gas outlet port. Finally, the gas outlet port has connected thereto and in fluid communication therewith a floating plug valve. The floating plug valve comprises a first plug movably positioned over and sealing a first aperture within the floating plug valve such that a first weight of the first plug and a first area of the first aperture define an upper operating pressure of a gas introduced into the storage tank through the gas inlet port. The apparatus of the present invention also contemplates a floating plug valve employed within the apparatus of the present invention.

In the apparatus, a main gas supply source and at least one back-up gas supply source are provided which are connected by a plurality of conduits to a process tool. The conduits further include pressure regulators such that a gas pressure from the main gas supply source is always regulated at about 0.5 Kg/cm2˜1 Kg/cm2 higher than a gas pressure from the back-up gas supply source. The apparatus operates by pneumatic means so that no electric power is required. The apparatus further operates automatically by switching from the main gas supply source to the back-up gas supply source when the pressure drop in the main gas supply source exceeds the pressure differential that is preset in the system, e.g., between about 0.5 Kg/cm2 and about 1 Kg/cm2. Any other suitable range of pressure differential may also be used depending on the type of gases transported and the conduits used.
