，但我的組織均不是二三十年內所能怯復的」'確屬

名言。優良的組織和管理，非一臨可就，品績經過相當的時間和付出相當的代價，其道萬端，非數言可盡。

不過，我認為「延攬人才」和「建立制度」是最基本

的著手點。所謂「人才」，不僅指技術入才，也指業諧和管理等人才，現代企業，講究的是吋旦旦司。其。一個成功的企業家必定是最會用人的領導者。所以，我們要想把事業辦好，一定要把眼光放遠，胸襟放寬，隨時留意人才，物色人才，和重用人才。

所謂「制度」'是指推動和處理業務的內部各種

制度，包括了人寧、會計、生產、檔案等等各種大小

制度。我認為

9就是要依賴制度來達到「紀錄完整

和「不因人麼事」

o

「紀錄完整」是指公司和主廠的

每日動靜態都有卷可查。「不因人麼事」是指公司或工廠中任何重要人員的缺席，不致影響生產和業瑟的進行。政府機構，大部建立了一良好的制度，但以牽涉而較賢，故手續甚繁，因此影響了效率，我以為 9我們不妨參考政府機構的某些制度，取其優點，避其缺點，來建立一種通合於自己的簡單和有殼的制度。如

果有了「人才」而叉建立了「制度」，則有關組織和

管理的問題，等於解決了一大半，單槍匹馬，個人英雄主義的經營古式，是遲早要被淘汰抽。啟

the applieb voltage stays the same no matter how much Current flows, so avalanche diodes are widely used as

voltag 巴 regulators.

Dr. Shockley found that by adding anoth巴 r section to the diode, he could control the amount of current flowing through the device under avalanche conditions. This means that it could be used as an amplifier like an ordinary transistor.

The advantag巴 of the new device is that in high power

operation

,

where much heat is generated

,

it won't develop hot spots as ordinary transistors do. This is because higher temperatures increase the voltage at which avalanche oecurs

,

so tha t if it gets too ho t, th巴 avalanche transistor automat-' icalIy shuts down before it damages itself.

Dr. Shockley says he likes the device because

“

it seems to be a transistor that operates as high as 10 megacycles." He assigned the patent to International Telephone and Telegraph Corp , which is now working to p巴rfectthe device. Patent 3,339,086.

according to BTL spokesm巴口，

Noise is reduced by a device known as a compandor (compressor-expandor)

It reduces the variations in loudness of the speaker's voice so that his spe巴ch is at an almost constant level. That meansthat all of his words can be amplified the same amount and be loud enough to be heard over any electronic noise in the background. At th已 receiver end

---區~-~ew·Trans!si.or Device

A high power transistor device that works well at high frequenciesand isn't bothered by temperature problems was patented last week by Nobelist Dr. William Shockley

,

who describes it as

“

one of my most faγorite" inventions. Dr. Shockley, now at Stanford

was co-inventoe of

the original transistor in 19生8.

The new deγice uses the

of known velocity were sent through a stack of thin metal foils enclosed in a vacuum. As they passed from metal into

th巴 vacuum， the 臼 transition" radiation was measured. The

intensity of the radiation in the forward direction was found to increase in a rehular way as the velocity of the particles we立 t up.

If the transition radiation detector can be developed, it will be useful to det巴rmine the unknown velocity of particles by the amount of radiation they give off. This in turn could be used to identify unknown particles.

Although other techniques can b巴 used to measure vel-oeity of slower moving particles

,

the known methods don't work when speeds approach the speed of light in a vacuum. The research is reported in the Aug 28 PHYSICAL REVIEW LETTERS
