Provided are a magnetic recording and/or reading apparatus and a method of manufacturing a power transmitting gear. The magnetic recording and/or reading apparatus includes a power transmitting gear. The power transmitting gear has one end coupled to a loading motor and the other end coupled to a plurality of link gears to transmit power from a loading motor to drive components during loading and unloading of a magnetic tape. The power transmitting gear includes a first gear engaged with a motor gear coupled to a shaft of the loading motor. The power transmitting gear also includes a second gear engaged with one of the plurality of link gears and a shaft member coupling the first and second gears. A space is formed inside the shaft member to prevent the shaft member from deforming during manufacture of the shaft member.

摘要:
An open-tube type impurity diffusion apparatus for simultaneously diffusing impurities into a plurality of wafers in a same controlled environment. The apparatus includes a diffusion box including a diffusion source, a diffusion box for holding a plurality of wafers, a slider including a body having a perforated portion and non-perforated portion and heaters disposed in a furnace. Because the apparatus can be used to simultaneously diffuse impurities into a plurality of wafers once, a mass of semiconductors can be produced, production cost and time can be decreased, and deviation of the wafer characteristics from wafer to wafer within a batch can be minimized.

A magnetic recording/reading apparatus comprises a head drum disposed on a deck to record or read information on/from a magnetic tape. An FPC fixing member is disposed on the deck to fix an FPC having a signal line to transmit a signal. The apparatus is configured to prevent noise generated between the head drum and the magnetic tape from transmitting to the outside and to a microphone. Thus, quality of recorded sound is improved.
摘要:
A head drum apparatus comprises: a lower drum; a stationary shaft pressed and fitted into a center hole of the lower drum; an upper drum rotatably coupled to the stationary shaft via at least one bearing; a boss fixed to the top portion of the stationary shaft by means of a set-screw; a motor rotor mounted to the top surface of the upper drum; a motor stator fixed to the boss, the motor stator being opposite to the motor rotor; and a ground device. The ground device includes an anchor member anchored to the upper surface of the boss and an elastic member fixed to the bottom surface of the anchor member. The elastic member extends downwardly through a bore in the boss, and a ground member is fixed to tile lower end of the elastic member. The ground member is in elastic contact with an outer race of an upper bearing. Accordingly, the assembly and the disassembly operations of the components of the ground device become simpler and easier, thereby increasing the productivity and enhancing the service operation efficiency thereof.

A liquid crystal display device (LCD) is constructed with a light blocking layer positioned on a data line region of a lower substrate defined by pixel regions and data line regions. A data line is positioned on the data line region of the lower substrate to overlap the light blocking layer with a gate insulating layer interposed therebetween. An organic insulating layer is positioned on the data line region of the lower substrate in order to cover the data line. Pixel electrodes are respectively positioned on the pixel regions to be spaced apart from the data line. Capacitors are respectively positioned on the pixel regions, and each of the capacitors has a lower electrode formed of a first transparent conductive material and an upper electrode formed of a second transparent conductive material, and the upper electrode is physically insulated from the data line with the organic insulating layer interposed therebetween.
摘要:
A lever fixing apparatus of a cassette housing has at least one lever for connecting a cassette holder to a chassis and at least one snap fixing unit for connecting the lever to at least one of the cassette holder and the chassis in a snap manner to hingedly fix the lever thereto. The lever fixing apparatus can fix the lever to the chassis without using additional coupling parts. Accordingly, the number of processes for assembling the cassette holder to the housing bracket can be reduced and the working time is saved, thereby the productivity being increased.
