早期原装的机械手表。这品相的很难得啊。


我觉得对老手表,老相机之类的收藏品来说,品相比牌子更重要。

The 1000/6.3 came complete with:

The lens itself
A huge reversible lens shade
A huge leather front lens cap
A huge protective rear cap large enough to be a salad bowl
Built in filters at the rear of the lens
A huge custom steel case proudly proclaiming "Reflex - Nikkor f=1000mm 1:6.3"
A small site built into the barrel to help point the lens
It is a HUGE lens. The lens and the case weighs 40 pounds!

Total 1000/6.3 production in Nikon Rangefinder mount  was about 45 units. The first lens was number 100630 or 100631.  The last reported lens is # 100680.   Total production in  F mount was about 60 units. The first F mount lens was 631000 and the last reported lens is # 631056.     The first 10 or so 1000/6.3's in NRF mount were all black. Production then shifted to a light gray crinkle paint.  A very few may have been made in Bronica mount

极少见的苏联相机。FED-2试制款。
Ziga的藏品。

Hi to all.

I've been reading this great forum for a long time, but I haven't posted here until today.

I recently acquired very early FED-2 with a serial number 000004 and stamped rangefinder window. Based on Aidas' page I believe this particular FED-2 is a new type since it has (compared to PE0350) a different rewind knob, different arrow engraved at the shutter speed selector and slide switch on the back side for the film rewind release. I have only late FED-2s with rounded rangefinder window to compare it to so I don't know if there are any internal differences compared to known preseries models.

Unfortunately it doesn't work - shutter release button is stuck - and previous owner tried to repair it and lost some screws. There is also a "focusing" knob missing on the lens.

I would like to hear your general thoughts on this particular camera and recommendation, where to get the missing parts and if replace them at all. Are the screws on  ...

I would like to hear your general thoughts on this particular camera and recommendation, where to get the missing parts and if replace them at all. Are the screws on the accessory shoe flat headed? I have little to none doubts that the camera is real since it was not sold by a dealer, but I would like to hear your thoughts on that as well since you are much more experienced than I am. Do you think I should get it fixed or leave it as it is?

Thank you for your time and have a nice day,

Ziga.

近日,由北方微电子公司自主研发的12英寸28纳米等离子硅刻蚀机,已经全面通过中芯国际集成电路制造有限公司的生产线全流程工艺验证,并获得客户订单。这标志着中国集成电路高端装备自主化取得了新的突破,并缩短了与国际一流设备的差距。

等离子刻蚀机是在硅片表面实现三维精细加工的高端设备,是集成电路制造中最核心的装备之一。当前,国际上进入量产的最高水平是28纳米技术,相比40纳米技术,可使集成电路的功耗更小、速度更快、成本更低,主要应用于CPU、存储器、移动通信、数字音视频等高端芯片产品。目前,国际上仅美国和日本各有一家企业能够提供满足28纳米生产线的成熟设备。
由于技术门槛高,高端刻蚀设备成为长期制约※※集成电路产业发展的瓶颈。目前,※※大规模集成电路生产线(8-12英寸)的芯片制造设备大量依赖进口,不仅严重影响※※集成电路产业发展,也对※※电子信息安全造成重大隐患。
北方微电子28纳米等离子硅刻蚀机通过自主创新,突破了精密等离子体控制、硅片表面温度精确控制、高气流均匀控制等多项关键技术,以全新的硬件设计达到了高速率、高均匀性、低损伤和低缺陷、精确尺寸和形貌控制、低颗粒污染等要求,多项关键指标达到国际先进水平。28纳米刻蚀技术的突破,打 ...


信息社会中不可或缺的集成电路芯片,则要靠光刻机来制造。光刻机在芯片制造业中的地位和作用就相当于机床在机械制造业中的地位和作用。一台光刻机中的核心子系统包括:超精密环境参数控制系统、大功率深紫外激光器、超大数值孔径的透镜组、纳米移动定位系统、超高精度多自由度移动工作台等等。
  目前上海微电子的光刻机能够刻蚀90nm的集成电路,距离国外先进水平还有相当的差距,不过这已经为中国的电子工业提供了相当的支持,毕竟并非所有的芯片都需要做到20nm。中国的自主CPU龙芯2F采用90nm制程可以达到800MHz的主频,性能高于1GHz的Pentium III,这就是说,中国已经可以自主掌握这一水平的CPU制造了,其经济意义和军事意义都不可低估。更为重要的是,在解决了有和无的问题之后,在此基础上中国将会继续冲击更高端的光刻设备,自主制造更高端的芯片。
  光刻机是一个极其复杂的光机电系统,其中的核心零件也都需要高端的特殊设备才能加工出来,比如光学系统中的透镜。为了降低衍射效应以便得到更细的线宽,光刻机中使用的激光波长只有通常可见光的三分之一,因此对透镜表面光洁度的要求比普通光学零件要高出三倍,为此必须使用特殊的抛光技术,才能满足其极为苛刻的形貌指标。
  光刻机所涉及的产业链非常长、非常高端,世界上没有任何一个国家可以完全独立地掌握其全部子系统的研发和制造技术。目前世界上最大的光刻机生产商ASML是荷兰公司,光刻机中的光学镜组来自德国、干涉测量系统来自美国,其产品可以说是整个西方世界科技成果的总和。在这方面,中国要想取得独立自主的发展,实际上是在以一己之力追赶所有发达国家数百年的积累,每一个单项的突破都意味着中国又追上了一步,这个过程将会是漫长而艰辛的。不过依托完整的产业链、庞大的工业产能和雄厚的人才基础,中国的IC产业最终实现全面超越是完全可以期待的。
