摘要:
An eye-opening margin measurement method for a high-speed serial data reception circuit which uses a circuit for eye-opening margin measurement involving operation of a clock data recovery circuit without fixing the clock phase. In this method, an error acceleration test can also be made on received data by giving an offset pulse signal to phase information to add a jitter component. The method uses a semiconductor integrated circuit device which includes a serializer/deserializer circuit (SerDes) for receiving serial data and a reference serializer/deserializer circuit (Ref_SerDes) for receiving an accompanying clock signal. The SerDes circuit converts received serial data into parallel data through a recovery clock whose phase is controlled using phase control signal P_CS generated by the Ref_SerDes circuit. An offset pulse signal Offset_Pulse from the pulse-forming circuit is applied to the phase control signal P_CS to make eye-opening margin measurement.

A capacitive element C1 having a small leakage current is formed by utilizing a gate oxide film 9B thicker than that of a MISFET of a logic section incorporated in a CMOS gate array, without increasing the number of steps of manufacturing the CMOS gate array. The capacitive element C1 has a gate electrode 10E. A part of the gate electrode 10E is made of a polycrystalline silicon film. The polycrystalline silicon film is doped with n-type impurities, so that the capacitive element may reliably operate even at a low power-supply voltage.

This invention relates to a precast gel for electrophoresis comprising a support filled with an aqueous gel prepared by polymerizing an aqueous solution comprising a radically polymerizable monomer, a crosslinkable monomer, a buffer, a redox initiator comprising an oxidizer/reducer, and a photo sensitizer and having a pH level of 6.0 to 7.5 via light application. The slab gel for electrophoresis of the present invention can produce a precast gel for electrophoresis within a shorter period of time and in an easier manner than is possible with conventional techniques. Accordingly, the present invention enables production of a high-quality precast gel for electrophoresis in terms of productivity, cost, and quality, and the industrial applicability thereof is remarkable.

A semiconductor device fabrication process comprising an encapsulation step of carrying out encapsulation by vacuum pressure differential printing by the use of a liquid resin encapsulant containing a solvent in an amount of from 5% by weight to 50% by weight, and preferably from 25% by weight to 50% by weight. The encapsulation step comprises: printing the liquid resin encapsulant by vacuum pressure differential printing in such a way that; the encapsulant covers at least an internal connecting terminal provided on a substrate, a semiconductor chip, and a wire interconnecting the internal connecting terminal and the semiconductor chip; and that the thickness of the encapsulant lying above the wire at the highest position of the wire comes to be at least 0.8 times the thickness of the encapsulant lying beneath the wire at the same position; and curing or drying the encapsulant.

A multi-mode image forming apparatus and method have a first mode which can be used by all users and a second mode which is available to authorized users only. The second mode is induced in response to a request from a management apparatus which is connected image forming apparatus. A reception arrangement is arranged to receive updating data sent from the management apparatus in the second mode and to store this data in a memory from which a non-volatile memory of the image forming apparatus can be updated at a later time. This arrangement permits file data to be transferred from the management apparatus to a HDD in the image forming apparatus. During an update, this data can be read out from the HDD to an EEPROM (non-volatile memory) so that even if the updating operation fails, the time for repeating the updating can be minimized.

A breakthrough buffer for a mechanical press (1) includes at least one buffer body (20) disposed between punch slide (2) and lower press frame (7) to cushion punch plate (3) during breakthrough of punch (4) through a workpiece, a timing regulator (40, 70, 90) connected to each buffer body for regulating timing of buffering during breakthrough, and a control system (60) to provide a command signal to this regulator to minimize noise or vibration occurring during the breakthrough. The control system includes a controller (63) which is responsive to the output of noise sensor (61) or vibration sensor (65) during breakthrough. The buffer body can include fluid driven buffer piston (22) in a buffer cylinder (21), with the buffer piston being associated with a guidepost (5). Alternatively, the buffer body can include piston (82) which contacts the guidepost and which is fluid driven (30, 81) in opposition to spring (83). The timing regulator can include an annular guide (46, 71) which is movable vertically by stepping motor (41) and worm gear drive (42, 44). A locking mechanism (73) can restrain trailing whirl of the guide. Alternatively, the timing regulator can include regulating piston (94) in regulating actuator (93), with fluid pressure on one side being controlled by proportional valve (91) responsive to the command signal, while fluid pressure on the other side is applied to each buffer piston.

An error rate of a bit synchronous circuit is decreased to a large extent by preventing following excessively the jitters included in input data. A phase detect circuit of a bit synchronous circuit includes a majority decision circuit. The majority decision circuit counts UP0 and DN0 signals as a phase comparison result of comparing phases by a UP0 counter and a DN0 counter for a period of time, and its count number is judged by a magnitude relation determination circuit. The magnitude relation determination circuit outputs an UP signal if the UP0 signal is majority, a DN signal if the DN0 signal is majority, and a FIX signal if the UP0 signal is equal to the DN0 signal. Accordingly, since it is possible to prevent following the jitters included in input data, etc., an error rate for bit synchronization can be reduced to a large extent.
