Are you certain? A "conventional" cap would not be able to retain the memory
very long. You need something 0.1F or larger -- and conventional caps rarely
come in that size.

I installed a supercap in my Lux tuner, and it holds the memory two or three
days.

I would concur with William. I have a 0.22F @ 5v on my desk at the
moment, it holds its charge for many days.

Lets get things correct here. Memory backup capacitors can have
very high capacitance values and extremely low leakage. That is
not in dispute. The term supercap does not refer to the typical
memory capacitor installed on consumer electronics equipment.
That is a different type that has high series resistance. If you
have a ESR meter, measure one for yourself but discharge it first
for a long time.

Thanks for your note.
Yes the cap I have is intended for memory retention service. I do have
an ESR meter but it hadn't occurred to me to actually measure it,
though I do take your point about discharging it first. I did
discharge it some time ago and was surprised by how much the voltage
had recovered the following day.

I'm not sure what the "typical" memory capacitor is. With respect to my Lux
5T50, the cap was one I selected and installed.

Hi William,
I found references to "Super Cap" on EPCOS website.
http://www.epcos.com/inf/20/25/ds/b32330_b32332_450.pdf
Not quite what I expected.

This is an AC starter cap -- dubbed a Super Motor Cap. Not the same thing.

Does anyone have a data sheet for a "Toshiba" IC Part No:TA7228P.
There is no sign of it on the Toshiba Electronics web site and google
just gets thousands of hits for merchants trying to sell parts.
This is an old IC that I discovered in a box that I was clearing out, so
its just curiosity on my part.

Thanks in advance for any info.

My vrt databook just identifies it as a 5.7W audio amplifier.

Thanks John, Is the TA7222AP an equivalent part ?

Hi Franc,
Thanks. I couldn't find any meaningful information on the net. I'm
guessing that the device must be around 20 years old or so.

Go to a Canon Service Station, that's a common CCD failure,
and Canon mostly will make a guarantee repair even when the
regular guarantee time is over.
Last known cost free repair had a friend in July this year
for his IXUS-400.

From: nosrah

Lady Aisha (may Allah be pleased with her) is what this humanity
possesses of bright mind, sharp wit, and abundant knowledge.
Additionally, for her effective role in serving the Islamic thought
through relating Prophet Muhammad's (PBUH) Hadiths (narrations);
interpreting a lot of the aspects of the Prophet's (PBUH) life and her
juristic deductions.
She is also a woman who exceeded the boundaries of her role as a woman
to become a teacher for a whole nation that is the Islamic nation.

May Allah be Pleased with her was one of the skilful people in Qur'an,
Hadith and Islamic Jurisprudence, thus Urwah- bin al- Zubair said:'' I
have never seen someone who knows more of the Qur'an and its
commandments, nor al-Hallal (lawfulness), or Haram( sinful deeds), or
poetry, or Arabs oratory or backgrounds than Aisha.''

In this researchable point I have raised three domains in which lady
Aisha (may Allah be Pleased with her) has been distinguished in, and
they are:

1-Her knowledge and teachings.

2-The oratorical interpreter lady.

3-The lady faqiha (Islamic jurist).

I have chosen these domains for their importance and obvious influence
on the Islamic community and thought, Lady Aisha (may Allah be Pleased
with her) with her knowledge and her knowingness contributed in
amending the concepts, and the orientation to follow the Messenger of
Allah's Sunnah (Prophet's tradition), that's why the intellectuals
used to go to her to grasp from her abundant knowledge ,thereby she
became an illuminative source (lamp) that sheds its light on the
people of science and its students .......
