IPC: G02B27/28
Filed: 1991-12-19
Abstract: PURPOSE:To prevent an extinction characteristic and to improve a yield so as to inexpensively obtain the optical isolator by adhering a Cd1-xMnxTe single crystal to the crystal adhering part at the front end of a holder and inserting this crystal into the central part of a permanent magnet in a manner as not to come into contact with the permanent magnet. CONSTITUTION:The optical isolator consisting of semimagnetic semiconductor cadmium, manganese, tellurium, and Cd1-xMnxTe (0<X<=0.7) single crystal as Faraday rotor materials is constituted by adhering the crystal 4 of the Cd1-xMnxTe single crystal to the front end of the hollow holder 21 disposed on the outside of the hollow permanent magnet 1 and inserting the crystal 4 into the central part of the permanent magnet 1 so as not to come into contact with the permanent magnet 1. Since the stress from the adhesive stuck to the permanent magnet 1 is not applied to the supporting part of the crystal 4, the extinction characteristic of the crystal 4 is not degraded. The degradation in the extinction ratio is controlled to 1 to 2dB by this method, by which the degradation in the extinction ratio is prevented and the yield is improved.

Title: Data processor having variable length code processing mechanism
Inventor: YASUSATO AKIRA
IPC: G06F12/04
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To execute VLC decode processing and VLC encode processing through a little instruction steps by loading variable length code data to a buffer register and shifting them out of the buffer register. SOLUTION: All the load/store width of BR0 and BR1 is assumed as 32 bits. In the decode processing, a left shift instruction designates a shift amount as an operand and shifts data to left just for the designated amount. Similarly, the value of OFFR is incremented just for the shift amount. When the value of OFFR is more than 32, a conditional load instruction loads the data of 32 bits on a memory with the value of AR as an address onto the BR1. and increments the value of AR just for 4. When the value of OFFR is more than 32, a conditional left shift instruction shifts the BR1 to left just for (OFFR-32) bits and replaces the part of (OFFR-32) bits of the BR0 with shifted-out bits. At the same time, the OFFR is decremented just for 32.
