Abstract: In an analog delay circuit having an analog-value memory circuit comprising memory cells arranged to form a matrix with each memory cell comprising a memory-cell capacitor and a select-switch device, read switches, write switches and reset switches are provided for the rows to form a read/write circuit. When a memory cell is selected, the capacitance of a parasitic capacitor connected to write and read nodes is reduced to the capacitance of a parasitic capacitor of one row selected by the select-switch device and, at the same time, electric charge accumulated in the parasitic capacitor of the selected row is reset by one of the reset switches provided for the selected row immediately prior to a read operation to read electric charge of the selected memory cell on the row, eliminating noise caused by the electric charge accumulated in the parasitic capacitor of the selected row.

Abstract: When a grounded conductive roller touches a transfer
drum through a transfer material while a voltage is
applied to a conductor layer, charges having a polarity
opposite to the polarity of the voltage applied to the
conductor layer are generated over the transfer material,
thereby making it possible to attract the transfer
material to the dielectric layer. Since the voltage is
applied to the conductor layer, the electrostatic
attraction of the transfer material and the toner
transfer can be carried out using a single power source.
Moreover, since the attraction of the transfer material
and the toner transfer are carried out by the charge
injection, a lower voltage can be used. Thus, the
voltage can be readily controlled while reducing the
ozone emission to a relatively low level. Furthermore,
since the toner transfer and electrostatic attraction of
the transfer material can be carried out using a single
power source, the apparatus can be downsized and less
expensive. In addition, when a semiconductor layer is
made of a solid elastic body, a high-quality transferred
toner image can be obtained without image quality
deterioration.

Abstract: An apparatus for retrieving data from a first network site for use by a second
network site utilizes a template that specifies the location of the data within a response
solicited from the first network site. The template is a mark-up document having a
similar format to the response and thus, it is not an application program. A marker is
included within the template to determine the location of the data within the response.
A matching mechanism, which may be used with any template, is utilized to compare
the template with the response to determine the exact location of the data within the
response. The data may be retrieved when its location within the response is
ascertained. Once retrieved, the data may be used by the second network site for
display in a format that is specified by the second network site. Accordingly, data is
located within the response with a template and not with a scanning application
program.

Abstract: The process involves pre-loading all bit lines to the blocking potential (VB) with the blocking decoder. All outputs of the word decoder are set to a protective voltage (VS) so all memory cells of the cell field are conducting and the blocking potential is carried over to the entire cell field. The blocking decoder is completely decoupled from the cell field so the blocking potential remains stored on the capacitors of the bit lines (BL). The bit decoder is switched on and connects a bit line with the line which holds the information value to be programmed. The information is transferred to the bit line. A word line is selected via the word decoder and set to the programming potential (VP). The memory cell is programmed, at the crossing point of the word line with the previously chosen bit line. Finally the word and bit decoder are switched off.

Abstract: An Fe-B-R based permanent magnet and metal pieces are
placed into a treating vessel, where they are vibrated and/or
agitated, whereby a metal film is formed on the surface of the
magnet. A sol solution produced by the hydrolytic reaction and
the polymerizing reaction of a metal compound which is a
starting material for a metal oxide film is applied to the metal
film and subjected to a heat treatment to form a metal oxide
film. Therefore, it is possible to form, on the surface of the
magnet, a corrosion-resistant film which can be produced easily
and at a low cost without carrying-out of a plating treatment
or a treatment using hexa-valent chromium and which has an
excellent adhesion to the surface of the magnet and can exhibit
a stable high magnetic characteristic which cannot be
deteriorated even if the magnet is left to stand for a long period
of time under high-temperature and high-humidity conditions of
a temperature of 80°C and a relative humidity of 90 %. Thus,
it is possible to provide an Fe-B-R based permanent magnet
