摘要:
A client signal having a constant bit rate is segmented every a bytes to create code information blocks. The bit rate of the client signal is increased such that the client signal has the code information block and an empty area comprised of b bytes, and the ratio c/a is equal to or higher than 110% to create a code block 3 comprised of c bytes. The code information block in the code block is encoded such that an error correcting code is included therein to have an encoding gain of 6 dB or higher for a bit error ratio of 10−12. Associated check bits are placed in the empty area to eventually generate a super FEC signal.

An object of the invention is to provide a medicine feeding apparatus in which a usability is improved by automatically executing a fine adjustment of a horizontal position and a vertical position of a door panel in correspondence to an operating of taking a drawer in and out without necessity of executing a troublesome mount fine adjusting work of a door panel. In a medicine feeding apparatus provided with a main body, drawers attached to the main body so as to be freely drawn, and a plurality of tablet cases detachably attached to the drawers and receiving medicines, a door panel of the drawer is rotatably held and is finely adjusted to a proper position in correspondence to an operation of taking the drawer in and out.

In an optical switching apparatus having redundantly-arranged optical switches, a route switching operation mode, an autonomic redundant switching operation mode and a compulsory redundant switching operation mode are discriminated from one another so that these operation modes are prevented from being executed at the same time, and also proper mask processing is performed at every switching operation mode. Therefore, emission of an undesired alarm and thus occurrence of malfunction when each switching operation is carried out can be prevented.

A machining strain removal apparatus for removing machining strain present on a treated surface of a workpiece, for example, a ground back of a semiconductor wafer by polishing the treated surface or ground back with a polishing tool with a high efficiency in a high quality. The apparatus includes a chuck for holding the workpiece while exposing the treated surface, and a polishing component for polishing the treated surface of the workpiece held on the chuck. The polishing component includes a polishing tool, and presses the polishing tool being rotated against the treated surface of the workpiece, thereby polishing the treated surface.

In a transmission network including multiplex transmission units A, F, G, D and E, when the line breakage has occurred on the OC-12 transmission path of the direction from unit A to unit F, the unit F detects the signal coming in from the OC-12 path indicative of the line breakage. The unit F inserts the APS bytes which comes in from the unit A into the undefined area of the OC-192 transport overhead which is reserved for the through-transport of APS bytes, and transports it to the unit G. On receiving the through-transport APS bytes, the unit G inserts it intact into the defined area for the APS bytes in the OC-12 transport overhead, and sends it to the unit D. In this manner, protection switching between the units A and D is carried out.

A grinding machine includes at least a turntable, rotary chuck tables for holding workpieces to be machined, a first grinding device for grinding the workpiece held on the chuck table and a second grinding device for grinding the first-ground workpiece held on the chuck table. The first grinding device comprises at least a first grinding wheel having pieces of grindstone set so as to define together a first grinding plane, and a first spindle fixed to the first grinding wheel. Likewise, the second grinding device comprises a second grinding wheel having pieces of grindstone set so as to define together a second grinding plane and a second spindle fixed to the second grinding wheel. The first and second grinding devices are so arranged that the first angle formed between the linear line connecting from the center of rotation of the turntable to the center of rotation of a selected chuck table and the linear line connecting from the center of rotation of the selected chuck table to the center of rotation of the first spindle is equal to the second angle formed between the linear line connecting from the center of rotation of the turntable to the center of rotation of the selected chuck table and the linear line connecting from the center of rotation of the selected chuck table to the center of rotation of the second spindle. This arrangement assures that all finished workpieces have the same thickness.

In a projection exposure apparatus used in lithography process for transferring a predetermined pattern formed on a reflection type mask onto a photosensitive substrate, the reflection mask and the substrate are moved relative to each other by a scanning driver, and the illumination optical system located between a radiation light source and the reflection mask includes a field stop located near a position conjugate with the reflection mask. In another embodiment a scanning driver changes the positional relationship between the reflection mask and the projection optical system, or/and between the substrate and the projection optical system. In another embodiment an image of the field stop is formed on the reflection mask by a relay optical system, preferably a catoptric system, forming the predetermined pattern. The projection optical system located between the reflection mask and the substrate directs the light reflected from the mask to the substrate, and illuminance distribution of the light on the exposure area of the substrate is adjustable by changing the position of reflection optical elements located along the optical path of the radiation light in the illumination optical system.

A multiplex type transmitting apparatus is arranged to have a plurality of slow signal receive/transmit sections for accommodating a counterpart for a SONET system or an SDH system, a multiplex separation converting section, and a receive/transmit section for a SONET system or SDH system fast signal. The slow or fast signal receive/transmit section includes a receive processing unit on a receive side for receiving the SS bits of the SONET/SDH system signal received from a transmission path, an internal SS bits setting unit for setting the SS bits of the received signal to internal SS bits if the SS bits of the received signal are “10” or “00”, a transmit processing unit on the receive side for transmitting a signal to the multiplex separation converting section as keeping the SS bits as “11” when an AIS-P is transferred, and a transmit processing unit on a transmit side for transmitting the signal from the multiplex separation converting section onto the transmission path as keeping the SS bits identical with the internal SS bits.
