Pertaining to the feeding quantity of Zn, the content of Zn per unit cubic volume of the epitaxially grown layer 5 is set at Sp pieces. After the time t2 has lapsed, a valve 10 is closed. Then, the opening and the closing operation of the valve is repeated, and when the formula Sn=Sp.t2/t1 regarding Sn, Sp, t1 and t2 is satisfied, the InP of i-type can be grown. After crystal growth has been finished, the epitaxially grown layer 5 is annealed. As a result, the p-type dopants are diffused, the unnecessary n-type dopants are cancelled by the p-type dopants, and homogenous i-type InP crystal can be obtained.

Title: Gas laser oscillator
Inventor: MURATA TAKAAKI
IPC: H01S3/0975
Filed: 1987-09-18
Abstract: PURPOSE:To make high frequency discharge in a laser medium uniform, by providing a specified gap between a pair of discharge electrodes, which face each other through a discharge tube, and the surface of the outer part of the discharge tube, and making a high frequency voltage that is given to the outer part uniform even if the discharge tube has error in size. CONSTITUTION:When a high frequency voltage is applied across discharge electrodes 23a and 23b from a high frequency power source 25, gas 22 is discharged at a high frequency and excited, and laser is outputted. An air layer 24 acts as if a capacitor is inserted between the discharge electrodes 23a and 23b. The electrostatic capacitance is distributed approximately uniformly over the entire air layer regardless of the error in size of an outer part 21a of a discharge tube 21. Therefore, the high frequency voltage is imparted to the outer part 21a of the discharge tube approximately uniformly through the air layer. Thus the uniform high frequency discharge in the gas 22 and the efficient laser output are obtained. The central part of the discharge electrode is brought closest to the outer part 21a of the discharge tube. The distance between the outer part 21a and the electrode is made wider as the part of the electrode is approached. Thus the discharge is made uniform.

Abstract: PURPOSE:To reduce the processing capability of software and to control easily the progress of a sequence by adding a specific sequence number to the data obtained by integrating the information showing the validity of a group of transfer data and transmitting and receiving the data for processing. CONSTITUTION:The data 1' transferred from a DTE 1 is stored in an RMEM 6 in response to each sequence number like the memory allocation 13. A muCOM 7 scans periodically an address (i) to read out the data 2'. If the data on the address (i) has a change, the reception data corresponding to the changed bit is read out and processed. Furthermore the data 3' is written to an address (j) of the memory storing the transmission data to be sent to the DTE 1 in the form of a display that detected and processed said change according to the allocation 14. A sequence number is added to the data on the address (j) and the data 4' is sent to the DTE 1. Thus the DTE 1 can confirm that an effective data group is processed with reception of the data 4'. Then the validity display bit is set at '0' at the data part of the number (i) to be transmitted succeedingly. Then the data 5' is sent to the device at the remote side. Fereafter the processing is carried out in the same way.
