sekolah,, pentingkah ???

sekolah??? tentunya kita tak asing dengan kata tersebut. sebuah kata yang selalu kita dengar tiap hari . sekolah merupakn rutinitas harian kita. tanpa kita berpikir panjang setiap hari kita selalu pergi ke sekolah . namun dibalik itu semua . apakah kita benar-benar mengerti arti sekolah ??? coba berfikir sejenak ....
pasti bayangan yang ada di adalah buku , bulpen ,seragam , guru , teman-teman sampai-sampai PR .
Bagi kita arti sekolah bisa bermacam-macam . ada yamg menganggap sekolah itu berangkat berangkat pagi pulang sore .Sekolah itu menyenangkan. sekolah itu tempat mencari pengetahuan . sekolah itu lan sekolah itu tempat dapat PR. sekolah itu .... blablabla..... . Sangat banyak sekali pendapat tentang sekolah dari yang positif sampai yang negatif. namun bersekolah pada hakikatnya adalah mencari ilmu agar kita bertambah Pandai .

Dengan bersekolah kita akan bertambah ilmu dan tentunya p[asti akan bertambah PANDAI. pandai ???? ya tentunyas . Tapi .. (lho kok ada tapi??) yup bagi kita yang memperhatikan dan bersekolah dengan sungguh-sungguh dan mau berusaha insyallah pasti kita akan tambah pandai . (yang bener..?) . ya iya lah... Bedain ama temen-temen kita yang nggak niat sekolah (pasti aku yakin temen-temen bukan bagian dari mereka) , suka bolos, nggak ngerjain PR , Cuma main , nggak merhatiin guru waktu nerangin , sekolah cuma buat rutinitas, sekolah cuma foya-foya (waduh ngeri) wah,,, pasti yang diajarin guru nggak ada yang nyangkut di otak mereka , kalo ada yang nyangkut pasti cuma dikit. Makanya ayo kita berusaha supaya jangan seperti mereka .
Dengan sekolah (bener-bener sekolah)
1.ilmu kita nambah tiap hari .
2.Berwawasan luas.
3.Memiliki akal dan budi peketi luhur n' tata krama.
4.Bertanggung jawab (kalo di kasih PR ngerjain).
5.Nambah saudara.
6.bersosialisasi dengan masyarakat .
7.Bermanfaat bagi semua.
8.Dicari banyak orang .
de el el , masih banyak sekali hal yang kita dapatkan dari sekolah.
semestinya bangsa kita nggak ketinggalan jaman .makanya ayo SEKOlAH . mari Tunjunan kepada Dunia kalo kamu emang Pemuda . Pemuda tu nggak cuma ikut-ikutan ,tapi tahu buat apa sekolah. kita adalah pemuda penerus bangsa , so jadikan indonesia jaya di dunia. SEMANGAT......!

UV TRON® DRIVING CIRCUIT

Hamamatsu C3704 series UV TRON driving circuits are low

current consuming, signal processing circuits for the UV TRON,

well known as a high sensitivity ultraviolet detecting tube. The

C3704 series can be operated as a UV sensor by connecting the

UV TRON and applying DC low voltage, as they have both a highvoltage

power supply and a signal processing circuit on the same

printed circuit board.

Since background discharges of the UV TRON caused by natural

excitation lights (such as a cosmic ray, scattered sunlight, etc.)

can be cancelled in the signal processing circuit, the output

signals from the C3704 series can be used without errors.

When the high sensitivity sensor “UV TRON R2868” (sold

separately) is used, the flame from a cigarette lighter (flame

length: 25mm) can be detected even from a distance of more

than 5m.

APPLICATIONS

l Flame detectors for gas and oil lighters

l Fire alarms

l Combustion monitors for burners

l Electric spark detector

l UV photoelectric counter
