摘要:
A high melting, high boiling organic compound is easily and stably purified by continuously supplying the molten organic compound to a rectification zone under a subatmospheric pressure and continuously distilling off and recovering vapors from the top of the rectification zone, while continuously withdrawing bottoms containing higher boiling impurities and/or involatile impurities than the desired compound from a reboiling zone at the bottom of the rectification zone to the outside of rectification system by means of a barometric leg, without any pretreatment of removing lower boiling impurities therefrom before the rectification, and without disturbing a pressure balance in the rectification system.

A semiconductor processing device according to the invention includes a first non-volatile memory (21) for erasing stored information on a first data length unit, a second non-volatile memory (22) for erasing stored information on a second data length unit, and a central processing unit (2), and capable of inputting/outputting encrypted data from/to an outside. The first non-volatile memory is used for storing an encryption key to be utilized for encrypting the data. The second non-volatile memory is used for storing a program to be processed by the central processing unit. The non-volatile memories to be utilized for storing the program and for storing the encryption key are separated from each other, and the data lengths of the erase units of information to be stored in the non-volatile memories are defined separately. Therefore, the stored information can efficiently be erased before the execution of a processing of writing the program, and the stored information can be erased corresponding to the data length of a necessary processing unit in the write of the encryption key to be utilized in the calculation processing of the CPU.

A solar cell 1 has a number of grooves 2 formed in parallel with each other on a first main surface 24a of a silicon single crystal substrate. An electrode 6 is formed on the inner side face of each groove 2 on one side. Each groove 2 is formed in the direction in disagreement with the direction on the first main surface 24a. This raises mechanical strength of the solar cell 1. The direction of formation of the grooves 2 preferably crosses the direction nearest to the direction of formation at an angle of 4°˜45° on the acute angle side.
