Title: Wiring error detector for a door operator
IPC: E05F15/00
Filed: 1992-01-29
Abstract: A door operation control system has a door opening for moving a door between open and closed positions. A door operator control circuit selectively operates the drive means to move the door between the open and closed positions. An obstruction detection device detects whether there is an obstruction in the path of the door between the open and closed positions and generates a signal in response thereto. The obstruction detection device is connected to the control circuit by wiring to permit operation of the door opener in the absence of a signal from the obstruction detection device and to prevent certain operations of the door opener in the presence of a signal from the obstruction detection device. An error detection circuit detects faults or errors in the wiring and generates a signal to prevent certain operations of the door operator when the faults or errors are detected. The error detection circuit prevents unsafe operation of the door opener if a wiring error has made the obstruction detection device inoperative. <IMAGE>

The digital voice patterns are converted into an analog signal. The analog voice signal is amplified in an amplifier and the selected numerals are output one after the other as voice signals via a loudspeaker 26. <IMAGE>
Patent EP-0664521-A3 (EP)
Inventor: IKEDA JUN
IPC: G06T11/60
Filed: 1994-11-11
Abstract: When input color data requests a draw logic
operation between pigments, an RGB draw operation is
performed under the control of a controller. The
controller performs a YMCK draw operation for a data
input which does not require a draw logic operation
between pigments so as to increase the number of
reproducible gradation levels, reproducible resolution,
and throughput. One of the RGB and YMCK draw
operations can be properly selected in accordance with
draw data supplied from a data source. A draw logic
operation between pigments for data which does not
require a draw logic operation between pigments can be
realized without reducing the number of gradation
levels and the resolution.

Patent EP-0735772-A3 (EP)
Inventor: BERETTA GIORDANO
IPC: H04N7/26
Filed: 1996-03-07
Abstract: A method of compressing color source image data includes forming
a quantization table with a "supra-threshold" term. This method includes
a step of selecting a set of target images, where each target image
includes one or more image elements such as text. These image elements
are then analyzed to identify those that are more important for visual
quality. These "supra-threshold" terms are then selected that gives a
larger weight to the quantization table elements that correspond to
important image elements and a smaller weight to the table elements
that correspond to less important image elements. This process
selectively weights the characteristics of each DCT basis vectors. By
giving larger weights to the table elements that correspond to the "up-downness"
of the image, i.e., the vertical attributes of the image elements,
and the "left-rightness" of the image, i.e., the horizontal attributes of the
image elements, and smaller weights to the table elements corresponding
to the "criss-crossedness" of the image, i.e., the diagonal attributes of the
image elements, the visual quality of an image that includes text can be
preserved while significantly increasing the compression ratio.

Abstract: There is provided a process for injection molding a
preform for stretch blow molding a thin-wall vessel such as a
bottle using amorphous polyethylene terephthalate (A-PET) as
a molding material, wherein a required amount of crystallized
polyethylene terephthalate (C-PET) is added to the A-PET.
The resulting mixture material can be easily plasticized to
increase the IV value of the molding material to a value
higher than that of A-PET so as to injection mold the
preform. A-PET which is hardly usable as a molding material
for stretch blow molding due to its low IV value is made
usable as a molding material for stretch blow molding by
increasing its IV value making use of plasticization at the
time of injection molding.
