The present invention relates to: a time and temperature indication module inducing a user to rupture an initiation member through an easy action such that a diffusing material contained thereinside is diffused through a crack caused by the rupture; and a method for manufacturing the time and temperature indication module, the method being capable of increasing the strength of a sealing part of the time and temperature indication module through a laminating process using a thermosetting method such that leakage or elution of the diffusing material is prevented.

The invention discloses a pipeline delay-based system and a method for measuring concentrations of components of fruit juice sugar. The system comprises a spiral pipeline sample cavity, a circuit box, an ultrasonic transmitting transducer and an ultrasonic receiving transducer, wherein the ultrasonic transmitting transducer and the ultrasonic receiving transducer are respectively located at the two ends of the spiral pipeline sample cavity; the circuit box is located outside the spiral pipeline sample cavity and is externally provided with display equipment; the circuit box comprises a main control unit, a memory, a transmitting circuit, a receiving circuit and a pulse detection decision circuit; the main control circuit is respectively connected with the memory, the transmitter circuit, the pulse detection decision circuit and the display equipment; the ultrasonic transmitting transducer is connected with the transmitting circuit in the circuit box, the ultrasonic receiving transducer is connected with the receiving circuit in the circuit box; and the receiving circuit is connected with the pulse detection decision circuit. In the method, the concentrations of the components of fruit juice are calculated through measuring the propagation time of ultrasonic in the spiral pipeline sample cavity. The method not only omits the step of calculating the sound speed to reduce the system computation but also effectively improves the detection accuracy.

The invention relates to a desk and chair, in particular to a desk and chair which is convenient for storage. The utility model provides a desk and chair which is space-saving and convenient to store and which is convenient to carry. A convenient storage desk and chair, comprising: a desk board; a storage box installed on the desk board; two support rods, installed on the storage box; Between the support rods; the pressing component is installed between the support rods; the backrest component is installed on the seat cushion component. The present invention uses the seat cushion assembly that can be stored, and the seat plate and its upper device can be folded and placed under the storage box, saving a lot of space; the present invention can not only fix the backing plate through the inclined plate, but also make the seat cushion assembly People can support it and store it at the same time without taking up space; the invention only needs to push the special-shaped rod to store the cushion assembly directly, and the equipment is more convenient to use.
