The resultant fluoride raw materials is heated under high vacuum of <=10-6 torr in the furnace at a temperature of room one up a prescribed one >=500 deg.C to remove moisture and oxygen. Then, the raw materials are molten, a flon gas is introduced to remove impurities and the objective fluoride bulk single crystal is formed by the melt-growth method. Thus, a crack-free and transparent cerium-containing barium lithium fluoride single crystal is obtained.

Title: Coding/decoding device
Inventor: INOUE SEIYA
IPC: H04B14/04
Filed: 1989-06-28
Abstract: PURPOSE:To obtain a coding/decoding device preventing the degradation in the error rate characteristic by detecting a delimiter of interleave with a code synchronization detection means and miniaturizing a device. CONSTITUTION:When a code synchronizing control circuit 21 discriminates that the synchronization of a code is not taken at an integration period, a block phase control circuit 22 shifts the phase of a block of de-interleave by one bit and when the circuit 21 decides the synchronous state, the circuit 22 keeps the phase of the delimiter of a current block. The code synchronizing control circuit 21 is used to fined out the delimiter of the interleaved block at a reception side and de-interleave is applied for each delimiter of the block and a Viterbi decoder 11 applies error correction decoding. Thus, the delimiter of interleave/de-interleave is implemented without the use of a unique word and a unique word insertion circuit, a detection circuit and a speed circuit, etc., are omitted. Thus, the bit rate in the transmission line is lowered by the absence of the unique word and the error is reduced.

Abstract: PURPOSE:To improve the utilizing efficiency of a common bus by providing an FIFO newly so as to preclude the possibility of useless monopoly of the common bus when a register being a transfer destination is not idle. CONSTITUTION:A bus control circuit 22 supervises whether or not a transmission request comes to a central processing section 1 and stores data to an FIFO 32 via an input circuit 21 on the occurrence of a request. When an FIFO 14 is idle thereafter, the data is sent from the FIFO 23 to the FIFO 14 and then the transfer is finished. When the FIFO 14 is not idle, the bus control circuit 22 transfers the data from the FIFO 23 to an FIFO 24 but does not transfer the data to the central processing section 1. When the FIFO 14 is idle on the occurrence of a request, the data in the FIFOs 23, 24 is transferred to the FIFO 14 to make the transfer complete (105). Moreover, when the FIFO 14 is again not idle, the FIFO 24 is updated or a 2nd data is invalidated.

Abstract: PURPOSE:To prevent residual image phenomenon from occuring by a method wherein a base region and an emitter region of a phototransistor are respectively connected to switches so as to control the elimination, storage and extraction of carriers. CONSTITUTION:A base region 3 of a phototransistor 1 is connected to a drain of a MOS transistor 5 while an emitter electrode 4 is connected to a regulated voltage source through another MOS transistor 8. When a gate electrode the transistor 5 is impressed with negative pulse phi RES, the potential of region 3 regardless of the value thereof represents the value of voltage source connected to a source electrode 7. The term in such a state is assumed as the first term. Next, in the carrier extinguishing process, transistors 5 and 8 are set up respectively in non-conductive state and conductive state.
