Title: Monitoring device for vehicle
Inventor: OMI OSAMU
IPC: B60R1/00
Filed: 1995-04-20
Abstract: PURPOSE: To provide a monitoring device high in the number of picture elements, small in outer diameter, capable of forming a sharp image and reduced in price by using a plastic multi-optical fiber for which circular light transmissive island parts being an image transmission body are arranged in a trapezoidal shape or in a zigzag shape in a sea part. CONSTITUTION: An image inputted from an object lens system 1 is guided through an image transmission body 2 to an image magnifying lens system 3 and a transmissive screen 4. The plastic multi-optical fiber in which 2,000-30,000 pieces of the circular light transmissive island parts (picture elements) having a diameter of 5-100μm are arranged in the trapezoidal shape in the sea part is used as the image transmission body 2. When the picture element system is smaller than 5μm, a transmission loss is increased and it is difficult to satisfactorily transmit the image. When the picture element system is larger than 100μm oppositely, the outer diameter of the entire multi- optical fiber is extremely enlarged and it is difficult to bend it.  Besides, when the number of picture elements is less than 2000, performance for discriminating the fine parts of an object to be observed is lowered and it is difficult to satisfactorily transmit the image. When the number is more than 30000, rigidity is enlarged and handlability is lowered.

Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To easily and speedily allot resources needed for multi-layered PCI bus architecture by grouping classified lists by first-fit algorithm and determining resource allotment to respective buses in bus layers. SOLUTION: A host processor 12 executes proper commands to determine a request to allot resources to respective devices. After this request is determined, requests of respective PCI (peripheral component interconnect) buses 19, 23, 25, 29, 36, and 39 in layers are determined. Then the buses 29 and 39 of the lowest order in the layers are discriminated and then resource allotment request of the device connected to the specific bus 29 or 39 of the lowest order is grouped into the request of the whole buses. This grouping acquires the resource request of the whole buses by using the first-fit algorithm.

Abstract: PURPOSE:To make it possible to prevent the leakage of steam even when an opening defect takes place in the packing head support of a turbine casing due to a secular change by a method wherein steam exhaust grooves are provided inside and outside a horizontal idle bolt hole. CONSTITUTION:When an opening defect takes place in the high pressure turbine casings 1 and 2 due to the long time use thereof, high pressure steam in the casings tends to leak outside. Therefore, in order to prevent such tendency, the steam 10 is, as a first step, introduced into a first steam exhaust groove 20 provided in the lower half section of the high pressure casing 1 and is discharged into a vent steam (a) section (not shown). Next, as a second step, a part of the exhaust steam 10 which has not been checked by the exhaust groove 20 is flowed into the idle bolt hole 22 and then discharged into the vent steam (a) section from a steam exhaust hole 23 drilled in the hole 22. Further, a part of the high pressure steam 10 which has not been checked even by the steam exhaust groove 20 and the exhaust hole 23 is introduced into a second steam exhaust groove 21 to thereby prevent the leakage of the steam 10 outside the casing completely.
