Title: Semiconductor acceleration sensor
Inventor: KATO KENJI
IPC: G01P15/09
Filed: 1994-10-04
Abstract: PURPOSE: To relieve film stress, and reduce the warp of a beam part of an acceleration sensor, by laying a Ti based wiring durable to etching solution, instead of A wiring, in the wiring part of a semiconductor acceleration sensor. CONSTITUTION: In a part of an Si substrate, a diffusion resistor 4 is formed, on the resistor 4, an SiO2 oxide film 5 is formed, and a Ti film 8 is formed. Since Ti is a metal durable to etching, a protective film is not necessary to be formed on the whole surface of the Ti wiring 8. Nitride film passivation 7 is formed in the uppermost part of only the contact part of the Ti wiring part 8 and the diffusion resistor 4. That is, the cantilever part of an acceleration sensor of the Ti wiring 8 is constituted as a two-layered structure of an oxide film 5 and the Ti wiring 8. As compared with the conventional Al wiring of three-layered structure, film stress can be relieved. Thereby the warp of the beam part of the acceleration sensor can be reduced.

Title: Optical circuit device
Inventor: KANAZAWA MAMORU
IPC: G02B6/122
Filed: 1987-09-28
Abstract: PURPOSE:To improve the dissipation ratio of a waveguide type polarizer by forming a thin film having an intermediate refractive index between the abnormal light refrac tive index and the ordinary refractive index of an optical waveguide on a substrate, and arranging a lens device so that the center of the device can be positioned off a three-dimensional optical waveguide on the thin film. CONSTITUTION:The thin film 3 having the intermediate refractive index between the abnormal light refractive index and the ordinary light refractive index of the waveguide 2 is provided on the three-dimensional waveguides 2 and 22 having optical anisotropy, and furthermore, the lens devices 4 and 21 are arranged on the film so that the centers of the devices can be positioned off the three-dimensional waveguide 2. As the lenses 4 and 21, a lunebery type lens or a diffraction grating type lens, etc., is used, and a material having the refractive index larger than that of the thin film is selected in the former type. Therefore, mode light to be removed coupled on the two-dimensional waveguide of the thin film is made incident on a lens part 21. Since the center of the lens comes off the three-dimensional waveguide 22, the focal point 23 of the lens is formed on a position separated from the three-dimensional waveguide, then, no focusing light is made incident on a fiber 24. In such a way, it is possible to improve the dissipation ratio of the waveguide type polarizer.

Title: Inter-processor communication instruction processor for virtual computer system
Inventor: YAMAGATA MAKOTO
IPC: G06F15/16
Filed: 1988-09-28
Abstract: PURPOSE:To process an inter-CPU communication instruction with the least overhead by using a means which checks the real processor state information and requests an idle processor to start a virtual processor. CONSTITUTION:An RP test circuit 145 gives an access to an RP state table 7 via an RP state table address 133 and searches an idle real CPU. When this CPU is searched, the circuit 145 writes a code into a communication area 3 to designate the execution of a dispatcher 9. Then an SIGP (inter-CPU communication) circuit 146 sends an interruption request to the real CPU. Receiving this request, the real CPU carries out the dispatcher 9 by reference to a dispatcher address 135. As a result, a virtual CPU kept waiting at the head of a VP queue 8 starts the scan over the real CPU. In such a constitution, the overhead caused by the production of an inter-CPU communication instruction can be reduced.
