Title: Growing method of compound semiconductor single crystal having volatility
Inventor: OZAWA SHIYOUICHI
IPC: C30B27/02
Filed: 1983-10-20
Abstract: PURPOSE:To grow a uniform and high-quality single crystal by covering the upper layer of the melt with a liquid capsuling material layer, and incorporating a specific melt floating layer into the lower layer in pulling up a III-V group compd. semiconductor single crystal from the melt in a crucible and drying. CONSTITUTION:The surface of a GaAs melt layer 23 in a quartz crucible 21 is covered with a liquid capsuling material layer (B2O3)22, and a melt floating material layer (Bi2O3)24 which does not react with the melt 23 and whose specific gravity and specific heat are higher than those of the melt 23 is placed under the layer 22. In addition, a film 25 of the melt floating material is formed on the inner surface of the crucible 21 contacting with the melt 24. Under said conditions, a seed crystal 29 supported by a lifting shaft 28 is passed through the liquid capsuling material layer 22, brought into contact with the melt layer 23, and lifted up while rotating to gradually grow a GaAs single crystal 30. The change of thermal conditions due to the decrease in the amt. of the melt during the growth of the single crystal is prevented by the liquid capsuling material layer 22, and the optimum conditions are maintained. The intrusion of impurities from the crucible 21 is prevented by the melt floating material layers 24 and 25, and the high-quality single crystal 30 can be obtained.

Title: Instrument for measuring mobility of carrier
Inventor: SAKAI AKIRA
IPC: G01N37/00
Filed: 1989-07-31
Abstract: PURPOSE:To effectively measure the mobility of a carrier by providing the second probe which is electrically insulated from the first probe at a position separated from the first probe by a fixed distance and using one of the probes as a probe for injection and the other as a probe for detecting injected carriers. CONSTITUTION:When a potential difference is given in advance to an electrode of a power source 14 fitted to a sample 3, injected electrons move along an electric field and, when they reach a point just below a probe 1, the electric potential is instantaneously changed and a pulse-like change is caused in the tunnel current between the probe 1 and sample 3. When the pulse is detected by means of a detection circuit 11 and the time lag between the detected pulse and the voltage pulse first applied across a probe 2 is measured with a timer 12, the flying time tau of the injected electrons can be found. When the interval (d) between the probes 1 and 2 is measured in advance by means of a scanning tunnel microscope STM, the average speed of the injected electrons can be found from v=d/tau (where, v = speed). Therefore, the mobility of electrons is measured at a very small area on the surface of the sample.

Title: Data transfer system
Inventor: MURAMOTO KOJI
IPC: G06F13/12
Filed: 1990-07-25
Abstract: PURPOSE:To reduce the overhead from the point of time when a data transfer request is made to actual data transfer by prefetching transfer data on a main storage device asynchronously with a data transfer request from an input/output device. CONSTITUTION:A local channel 4 prefetches the transfer data on the main storage device 2 according to control information from a remote channel 5 and transfers the data to the remote channel 5. The transferred data are received by a receiving circuit 55 and stored in a data buffer 51. The data buffer 51 is divided into areas by subchannels and when the receiving circuit 55 receives the transfer data, attached control codes are set in a channel control circuit 50; and the control codes are decoded and then addresses where the transfer data are stored are indicated to the data buffer 51. Then a channel control circuit 50 repeats operation until byte counting is carried out to the end and thus continues to prefetch data. Consequently, the overhead for each data transfer request is reduced.
