Abstract: PURPOSE:To obtain the optical waveguide which has small return light to a semiconductor laser. CONSTITUTION:When the wavelength of incident light on the optical waveguide as to incident light on the light incidence end surface 2a of the clad layer 2 of the optical waveguide and the light incidence end surface 3a of the optical waveguide layer 3 is denoted as lambda and the refractive index of the medium of the optical path for the incident light up to the optical waveguide is denoted as (n), the optical path difference DELTAL between the incident light on the incidence end surface 2a of the clad layer 2 and the incident light on the incidence end surface 3a of the optical waveguide 3 is made to be an odd multiple of quater wave length of incident light i.e., (2i+1) lambda/4n (i: 0, 1, 2, 3<). Consequently, the phase of reflected light from the incidence end surface 2a of the clad 2 becomes reverse to the phase of reflected light from the incidence end surface 3a of the optical waveguide 3, so the laser light which is reflected by the end surface of the optical waveguide is not supplied as return light to the semiconductor laser 4 to eliminate the unstableness of the operation of the semiconductor laser 4 such as variation in the oscillation output of the semiconductor laser 4 and a mode hop phenomenon due to the return light.

Inventor: SHIMURA TAKUYA
IPC: G06F12/08
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To shorten the transfer time of cache data in an exclusive control and to improve the performance of a multiprocessor system by providing a temporary ineffective state as a state of a cache line to be invalidated since an exclusive control instruction issue source does not always change data. SOLUTION: A cache control part has an ineffective state, an exclusive state, a shared state, a changing state, and a temporary ineffective state s cache states. When an exclusive control instruction is issued and a corresponding cache is in the exclusive state or shared state, the cache is placed in the temporary ineffective state and the cache data are not made ineffective. When another CPU or node in the system issues a read request to the corresponding address and a cache snoop result in the system is unchanged, data are read out of cache lines in the temporary ineffective state. Consequently, the data transfer time is eliminated to be able to reduce a deterioration in performance.

Title: Vacuum valve
Inventor: OKAZAKI TAKAYUKI
IPC: H01H33/66
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To prevent a metallic film from sticking inside a vacuum vessel by restraining a flow by this barrier member by installing a metallic barrier member for controlling a flow of metallic vapor at least on one side of the shaft direction of an arc shield. SOLUTION: A barrier member 1A composed of a ring-shaped metallic plate is installed in the upper bending part 2A of an arc shield 2, and a fixed rod 5A is penetrated through this inner cavity. Since the clearance between the barrier member 1A and the fixed rod 5A becomes narrower than usual, metallic vapor generated from a contact point hardly reaches an upper inner wall of a vacuum vessel 3, so that a vacuum valve stands electric current shutoff of the large number of times so as to lengthen the service life. The barrier member composed of a ring-shaped metallic plate is installed in the lower bending part 2A of the arc shield 2, and may be formed as a structure for penetrating a movable rod through this inner cavity.
