Abstract: PURPOSE:To enable to use the system also to the transmission line with band limit such as radio transmission lines, by using the multiplexing bit rate in the middle band of each hierarchy group. CONSTITUTION:In the bit multiplexing system of each digital multiplexing signal of primary group of 2048Mb/s, secondary group of 8448Mb/s and the third group of 34,368Mb/s, each bit rate of the first to third hierarchy groups is made into low order group bit rate by using the multiplexing bit rate at the middle band of each group as listed in Table 1, for duplexing or triplexing, and the multiplexing bit rate having the bit rate and justification rate as listed in Table 1 is obtained. Thus, the rate of clock increase is small, the frame synchronizing return time is shorter, and the constitution is made that the justification jitter and the residual jitter of waiting time jitter can be small, then the digital signal at the middle of each hierarchy group can be fed even to the radio transmission line where occupied area is limited.

Filed: 1990-03-06
Abstract: PURPOSE:To increase or decrease the quantity of radiation reaching a sample from a radiation source speedily by rotating and moving the sample while making a reactor internal tube, which contains the sample, eccentric. CONSTITUTION:While a nuclear reactor is in an operation state, a reactor core 2 emits much radiation and the reactor internal tube 3 inserted into a container 1 and the sample S are irradiated with the radiation. Then the irradiation quantity becomes small when the sample S is put away from the reactor core 2 or large when the sample comes close. For the purpose, a rotary driving source 5 is put in operation and then its turning force is transmitted to the reactor internal tube 3, which is swiveled horizontally on a center line X of rotation by the eccentricity to move the sample S stored in the reactor internal tube 3 at the lower part in the direction where the opposition distance between the sample S and reactor core 2 becomes small or large, thereby causing transient variation by which the irradiation quantity of the sample S increases or decreases continuously. Further, a place where a radiation attenuator is increased or decreased is provided on one side of the sample S to cause the transient variation even when the direction is changed by the horizontal swivel.

The dummy silicon oxide films 16 are removed from MOS type transistor regions but retained on bipolar type transistor regions, and then gate oxide films 19 are formed in the regions now free of their oxide films 16. Accordingly, Si3N4 15 may be removed concurrently with the dummy silicon oxide films 16, which keeps constant the impurity distribution in the bipolar type transistor regions. This design ensures a sufficiently high breakdown strength.
