Title: Very noiseless motor driven centrifugal fan
IPC: F04D29/66
Filed: 1989-05-09
Abstract: The motor driven centrifugal fan (10) 
according to the present invention 
has the inner surface (18) of the volute (12) and possibly also the inner 
surfaces of the sidewalls (13) laterally defining the volute which are 
roughened.

shape, for example of orange-peel type, or of regular shape, for exam­
ple regular polygons or circles which can be arranged along parallel 
lines which are or not offset from each other.

Title: Multi-processor system
IPC: G06F15/17
Filed: 1989-06-06
Abstract: Disclosed is a multi-processor system in which 
central processing units (10,20) each provided with a main 
storage unit (13,23), an extended storage unit (14,24), an instruction 
processor (11,21) for making access to the main storage unit (13,23) or 
extended storage unit (14,24) through a storage control unit (12,22), and 
the storage control unit containing an interface control (15,25) 
for making communication between one central processing 
unit and another central processing unit are coupled with 
each other through the interface control, in which each 
of the central processing unit is operable by an 
independent operating system. In this system, the 
operating system for each of the instruction processor (11,21) 
permits an access to the extended storage unit (14,24) or each 
of the central processing units by specifying an 
identification number set for the extended storage unit 
thereof. This enables the extended storage unit to be 
shared in the system because the extended storage unit is 
accessible directly from each of the central processing 
units.

Abstract: A permanent non-erasable memory (16) stores formatting 
data and command bit patterns for a plurality of 
devices of different categories manufactured by 
different manufacturers to be controlled by the remote 
control transmitter incorporating the memory. To select 
the correct format, the user activates an enter initiate 
key, thereafter a key to indicate the category of the 
selected device, and thereafter two digits which together 
signify the manufacturer and model number. The keyboard 
output signals resulting from activation of tne keys 
are stored in RAM (44) in the microprocessor (10) controlling the 
remote control transmitter's operation. The stored values 
in RAM constitute an address for the memory. Under 
microprocessor control, the data read out from memory 
is then applied to the transmitter driver circuit (29) to 
cause the properly formatted device control signal to 
be transmitted.

Title: Traversed (d, k) code translation
IPC: G11B20/18
Filed: 1989-04-20
Abstract: Uncompressed data is represented in a constrained code for transmission 
through a channel which may include record media. A d,k code having a 
code rate of m/n is employed. "d" represents the minimum number of 
successive zeros in the channel code while k represents the maximum 
number of zeros in the channel code. "n" is an integer representing the 
number of code bits in a channel group. The encoding and decoding 
follows a sliding block coding and decoding algorithm. In the channel 
coding, the number of successive ones is limited to being not less than 
two, in some coding it can be a value of d-1. The modification of the 
d,k code results in decreasing error propagation while increasing the 
recorded information density. This increase is achieved by increasing 
the channel code dictionary.

Abstract: A method and apparatus are provided for 
controlling the working depth of a bucket for an 
excavating machine (100) having an outreach boom (102) 
which is pivotally attached at one end to the machine, a 
downreach boom (108) pivotally attached to the opposite 
end of the outreach boom, a digging bucket (112) pivotally 
attached to the end of the downreach boom opposite to that 
to which the outreach boom is attached, and hydraulic 
power cylinders (116, 118, 120) for moving the pivotally 
interconnected elements. A laser beam (126) is projected 
at a reference height and a beam sensor (128) mounted on 
the outreach boom (102) of the machine detects the beam 
(126) by means of a plurality of individual sensor 
locations. The angular orientation of the downreach boom 
(108) relative to vertical is detected by an angle sensor 
(134, 136, 138, 140, 142) and a microprocessor controller 
(150) connected to the beam sensor (128) and the angle 
sensor (134, 136, 138, 140, 142) repetitively defines, as 
a function of the angular orientation of the downreach 
boom (108), one of the plurality of individual sensor 
locations (C1-CX) as an on-grade sensor location. The 
microprocessor controller (150) compares the defined 
on-grade sensor location to the sensor location having 
detected the laser beam to generate an outreach boom 
adjustment signal representative of the movement of the 
outreach boom (102) which is required to maintain the 
bucket (112) on-grade as the downreach boom (108) is 
pivoted with respect to the outreach boom (102).
