Title: Method and device for automatic frequency control of semiconductor lasers
IPC: H01S5/40
Filed: 1989-03-30
Abstract: In the method for the automatic frequency control of semicon­
ductor lasers, the signal emitted from the laser (1) is sent to an 
optical resonator (6) whose resonance frequency is modulated by a ramp 
signal, the signal outgoing from the resonator (6) is converted into 
an electrical signal, the derivative of such an electrical signal is 
calculated, the zero crossing of the derivative is detected, the ramp 
signal is sampled in correspondence with such a zero crossing, and the 
sample thus obtained is algebraically summed to a reference signal 
dependent on the nominal laser emission frequency, thus obtaining an 
error signal which is sent to devices (3) driving the laser (1). In 
case of a plurality of lasers (1a..1n) the signals of which are wave­
length multiplexed, the ramp signal is sampled in correspondence with 
the derivative zero crossings corresponding with the emission frequen­
cies of the individual lasers (1a..1n), and the samples thus obtained 
are compared with respective reference signals, obtaining a control 
signal for each laser.  
     A device for implementing the method is also supplied.

Title: Hot backup file-server system
IPC: G06F12/00
Filed: 1989-09-07
Abstract: A computer system includes a main file server 
(20) and a backup file server (25). An overseer unit 
(30) within the system periodically causes the backup 
file server to be updated by copying new and 
therefore unbacked-up records from the main file 
server to the backup file server. If the main file 
server becomes unusable, e.g. because of a crash, the 
control unit diverts user logon requests to the 
backup file server.

Title: Semiconductor integrated-circuit device metallization
IPC: H01L21/28
Filed: 1989-12-01
Abstract: In the manufacture of an integrated-circuit device, periodic interruption 
of grain growth during chemical vapor deposition of a metal film results in enhanced 
surface smoothness and ease of patterning. Interruption of grain growth is by 
deposition of an auxiliary material which, in the interest of high conductivity of the 
film, may be conductive, may form a conductive compound or alloy, or may be 
eliminated upon additional metal deposition. When the metal is tungsten, silicon is a 
preferred grain-growth interrupting material.

Abstract: A material processing system has a plurality of material 
processing stations, one of which is a base material processing station. 
Material is directed to be processed serially through said plurality of 
processing stations in a given order to said base station. Such an 
arrangement is improved by providing that each of said plurality of

means responsive to said control signal for executing each processing at 
each said station, and means responsive to a completion of each station 
processing for providing a completion signal to the next successive 
station along said communication loop. The system may be used in a

gehende Spinnlösungsmittelentfernung bei hohen Spinnge­
schwindigkeiten notwendigen) hohen Temperaturen in Luft, 
ohne daß inerte Gase als Spinnluftmedien eingesetzt

Title: Pump with separate fluidizing vaned shaft adjacent impeller
IPC: F04D7/04
Filed: 1990-07-06
Abstract: A pumping system (10) is capable of handling a paper pulp suspension of medium consistency (e.g. about 8-15% solids consistency) utilizing a conventional centrifugal pump (12). A conventional pump system capable of handling 3-8% consistency pulp may be retrofit to handle 8-15% consistency pulp. A tube (30) with vanes (33), and having an open end (37), extends through the inlet (15) to the pump so that there is a small clearance (35) between the vanes and the inlet, and so that the open end is adjacent but spaced from the hub (18) of the pump impeller (17). A gas passage (48) extends from the hollow interior of the tube to an area remote from the pump. The tube is rotated in a direction of rotation opposite to the direction of rotation of the pump impeller, and at a speed sufficient to fluidize pulp of about 8-15% consistency, and to force the pulp toward the pump. Gas which collects at the pump impeller is withdrawn through the tube and the gas passage in a shaft (39) connected to the tube, and for that purpose a vacuum pump (52) may be utilized.
Patent EP-0435852-A3 (EP)
Title: Disk format for secondary storage system
IPC: G11B20/18
Filed: 1982-10-04
Abstract: In a disk type mass storage facility for data processing systems, a disk format which improves handling of defective segments of medium and reduces access time. The format has three layers. A first, physical layer comprises the bytes, sectors and collections of sectors, as well as error detection and correction codes. A second, logical layer is used to address the physical layer and to collect together sectors to form multiplicity of separately addressable spaces, with space having a distinct functional utility. As a third, functional layer the use of data fields in each space is specified. This layer governs the handling of bad blocks if required, and the use of certain format information. At the physical layer, bits are collected into sectors, sectors are collected into tracks, tracks are collected into groups, and groups are collected into cylinders. These are logically, rather than physically, defined collections. A group is set of tracks wherein individual tracks in a group can be selected in the inter-sector rotation time. At the logical layer, the disk is divided into three main areas, each separately addressable. The first main area is broken down into two sub-areas. The first subarea (12) is available to the host computing system for its use; the second sub-area (14 and 16) is used for replacement of the bad blocks. The second is for format information. The third main area (18) is for diagnostics. Handling of bad blocks is controlled by a hierarchically layered process. A portion of each disk, distributed across the medium, is reserved as spare sectors to replace defective sectors. After a bad sector is replaced, future attempts to access the bad sector are redirected (i.e., revectored) to the replacement sector. For the simplest revectoring, the bad block is replaced by a replacement block in a known location. If that cannot be done, multiple copies of the replacement block's header are stored in the bad block's data field and the copies are compared to find the replacement address. If the comparison fails, or the header cannot be read, a back-up table is available to match the available replacement addresses with the original address which was replaced. A special code is used to identify blocks wherein the medium is good but the contents of the block are logically corrupted. <IMAGE>
