Title: Semiconductor memory device having function of generating write signal internally
IPC: G11C7/10
Filed: 1989-02-02
Abstract: A semiconductor memory device includes : a circuit (43, 
45, 46) for defining a cycle (t R , t W ) in response to a clock (CLK) 
and a write enable signal ( WE ) and outputting a write control 
signal (WS) under a specific condition; a unit (30) for inverting 
the clock to an inverted clock ( CLK ); a circuit (47) for 
generating0 a write signal (WP) in response to the inverted clock 
when the write control signal is output; and a memory cell array 
(40, 40a, 40b) in which a write access of data (D IN ) is carried 
out based on the write signal. A register (44) is further provided 
which latches the write data (D IN ) and transmits it to the memory 
cell array in response to the inverted clock and the write signal. 
An input terminal and an output terminal can be made common (T5) 
by making a latch timing of the write data different from that of 
the write enable signal, or the number of input terminals can be 
decreased by inputting the write data in a time sharing mode. This 
results in a decrease in scale of the whole circuit as a device.

Abstract: A method of forming a nonsilicon 
semiconductor layer on an insulating layer by forming a 
thin heteroepitaxial layer (20) of nonsilicon semiconductor 
on a first substrate (10) having a lattice structure which 
matches that of the heteroepitaxial layer. A first 
insulating layer (30) is formed on the heteroepitaxial 
layer. A second insulating layer (50) is formed on the

a preferred embodiment the heteroepitaxial layer is 
germanium, gallium arsenide or silicon-germanium alloy 
while the first substrate is silicon, germanium, 
gallium arsenide or silicon-germanium alloy.

Abstract: A probe head (10) for orientating a probe relative to a 
head of a coordinate measuring machine, has a support 
(12), a rotor (14) rotatable relative to the support (12), 
and a swivel (18) rotatable relative to the rotor (14). 
The rotor (14) and swivel (18) are mounted for rotation 
through a series of discrete, and repeatable rest 
positions. The relative orientation of support (12), 
rotor (14) and swivel (18) is detected by an indicating 
mechanism comprising a printed circuit board (34) having a 
series of electrical conductive elements (36) and (38) and 
a contact arm (40) mounted for rotation over the 
conductive elements on the circuit board (34). When the 
electrical contacts (42) to (46) come into register with 
the conductive elements (36) on the circuit board (34) a 
pulse is transmitted to a micro-processor (50) which 
determines the relative orientation of e.g. the support 
(12) and rotor (14); this is shown on an LCD (52). The 
micro-processor may also provide instructions (on the LCD 
(52)) indicating in which direction the rotor (14) should 
be moved in order to attain a predetermined position 
stored in a memory of the micro-processor; an indication 
is provided on the LCD (52) that such a predetermined 
position has been attained.

IPC: H02P27/02
Filed: 1991-12-12
Abstract: An induction motor control apparatus for controlling the power factor at which an induction motor 12 operates includes sensors and circuits CT, 22; 16, 24; 26 for periodically detecting the effective (RMS) values of current and voltage supplied to the motor winding during a fixed number of cycles, e.g. one cycle, and multiplying these to obtain a value of apparent power of the motor, together with circuits CT, 146, 28 for detecting the working power of the motor, with the power factor of the motor being thereby accurately obtained. That detected power factor is compared with an ideal value of power factor, to obtain an error amount that is applied to control the motor voltage. The ideal power factor is obtained by multiplying a designated value of power factor by a compensation amount that is determined in accordance with the motor load, thereby ensuring that stable operation of the motor is achieved even under the no-load condition. <IMAGE>   <IMAGE>

Filed: 1990-06-15
Abstract: A sheet overlapping detecting method for use with sheets of unstable density includes the following steps. Light is radiated through a sheet of paper by N light emitting means and detected by N light detecting means, respectively, which generate a corresponding signal. The maximum light intensity signal is then selected and compared with each remaining N-1 signals to generate corresponding difference values associated with each N-1 signal respectively. The difference values are then compared with a predetermined value  @  @ d and the corresponding light intensity signals of all difference values which exceed this value are rejected. The average value Dr of the remaining light intensity values is then calculated and compared with a prestored overlapping determination value to determing whether overlapping of sheets has occurred. <IMAGE>

Abstract: The object of the invention is a method or protocol for the adaptation of digital
multimedia data flows at variable speed (the quantity of information of the flow
is not constant within the time unit), for services requiring the synchronization
of the receiver with the source, in the payload of ATM cells transmitted, at their
turn in a discontinued way. The method is based on the identification of a set of
M j  integer information blocks of one of the components of the multimedia flow
generated with a constant recurrence frequency T Mj  and including a
whatsoever number Bl of integer data blocks of each other I-th multimedia
component. 
     The set is therefore inserted together with additional service data in the
payload of Ni ATM cells in such a way that it will be possible to identify the first
 n (1<=n<<Ni)  payloads of the Ni cells from the others e.g. through the insertion
of a START byte into the first n cells. The timed transfer of such groups of Ni
cells with timing equal to the period T Mj  guarantees the transfer of the timing
from the source to the receiver.

Abstract: A system and method for discovering consumer purchasing tendencies
includes a computer-implemented program which identifies consumer
transaction itemsets that are stored in a database and which appear in
the database a user-defined minimum number of times, referred to as
minimum support. Then, the system discovers association rules in the
itemsets by comparing the ratio of the number of times each of the large
itemsets appears in the database to the number of times particular
subsets of the itemset appear in the database. When the ratio exceeds a
predetermined minimum confidence value, the system outputs an association
rule which is representative of purchasing tendencies of consumers.

Abstract: Recording and reproducing a television signal with a DC shifter prevents
compression distortion of a PAL plus television signal. The PAL plus television
signal includes a vertical resolution signal, for enhancing vertical resolution, which
is included in the same compression blocks as some of the component video signals.
Such compression blocks are shifted to a DC set up value so that the signals within
those compression blocks do not have varying DC offsets which otherwise could
result in compression distortion. Similarly, upon reproduction, the DC set up value
is removed after decompression and the original television signal is restored with
complete vertical resolution.

boost converter function and the buck function have

converter (30) reduces parts count, as compared to the
parts count required for
the separate boost and buck circuits of the prior art, by
making some components of the single circuit act
simultaneously in both the boost and buck functions. The
rigid forcing of the ac input current waveform to follow
the ac input voltage waveform is relaxed, to give
performance priority to the buck function for the common
components. Harmonics are allowed to enter the system in
moderation in return for a less expensive and more
