Original address: http://leihuang.org/2014/12/03/simple-factory/Creational modeThe production of objects needs to consume system resources, so how to produce, manage and manipulate objects efficiently is always a subject to be discussed, the creational model is related to the establishment of objects, and the model under this classification gives some guiding principles and the direction of design. Listed below are all belong to the creational mode

orchestra and the military band, this group of instruments is called the canal group. Correspondingly, the lip-spring musical instrument is called the brass tube group (in fact, these kinds of instruments are indeed made of copper ). next we will introduce these instruments.

The appearance of digital camera and digital camera makes the connection and transmission of camera, camera and computer more convenient. The 4 "I" (iphoto/imovie/idvd/itunes) of Mac OS X 10.2 Systems showcases the concept of digital video and digital Life for beginners and home users. Where iphoto is a digital photo management editing software, imovie is a video movie editing software, iDVD is a DVD burnin
I. Chinese semiconductor device model naming method
The model of a semiconductor device consists of five parts (the models of the Field Effect Device, special semiconductor device, composite tube, pin tube, and laser device are only part 3, 4, and 5. The five parts have the following meanings:
Part 1: digital representation of the Number of valid electrodes for a semiconductor device. 2-diode, 3-Transistor
for switching power supplies and motor drives. In the following introduction, NMOS is also used.
Parasitic Capacitance exists between the three pins of the mos tube. This is not what we need, but is produced by manufacturing process restrictions. The existence of parasitic capacitors makes it difficult to design or select the driving circuit, but there is no way to avoid it. I will introduce it in detail later. A parasitic diode exists between the dr
The dual-tube telescope is a useful astronomical observation tool. You can use it to watch a game, concert, or birds in the sky. You can also use it to enjoy the galaxy, the crater on the moon, several satellites around Jupiter and countless stars 2 million light years away. Many people mistakenly think that the dual-tube telescope is not used for astronomical observation. In fact, it is a favorite tool of
One, to solve the problem that QuickTime recording screen can not bring sound:Use the QuickTime screen under MacSoundflower->audio Setup->soundflower (2ch), the right mouse button, in the pop-up menu, "Use this device for sound input" and "Use this device for sound output" are dimmed.At this point we can no longer hear the sound of the Mac, but can record a recording screen with a sound through QuickTime.You need to set it up before the QuickTime recording screen:After recording, in order to hea
I. Digital Display Principle
We use the seven-and eight-segment LED digital tubes most often. The eight-segment has a decimal point while the other is basically the same. The so-called eight-segment is that there are eight small LED light-emitting diodes in the digital tube, and different shapes are displayed by controlling the light-off of different LEDs. Digital tubes can be divided into two types: Common cathode and common anode. In fact, the total

The specifications and parameters of ball tubes include the structure parameters and electrical parameters. The former refers to the various parameters determined by the structure of the ball tube, such as the tilt angle of the target surface, effective focus, shape size, weight, filtration equivalent of the tube wall, anode speed, operating temperature and cooling form. Electrical Parameters refer to the s

Two-way thyristor has primary electrode 1, primary electrode 2 and control pole. If the resistance between two primary electrodes is measured with A multimeter R × 1k, the reading should be approximately infinite, the positive and reverse resistance readings between the control pole and any prima
