A first connector 30 mounted on an upper surface of a substrate 10 has a first contact 38 which contacts with a card 32 inserted from one end and extends through a through hole 22 of the substrate 10 at the other end. The first contact 38 is supported by the first connector 30 in a distant position from the substrate 10, and a connecting portion 38c thereof and the through hole 22 are spaced apart. A second connector 60 has a second contact 66 which contacts with an external connector 90 inserted from one end and the connecting portion 38c of the first contact 38 inserted from the other end. The substrate 10, the first and second connectors 30 and 60 are connected each other by connection between the connecting portion 38c and a spring 66c. The first and second connectors 30 and 60 include shield shells 40 and 68 covering the first and second connectors 30 and 60, respectively, and the shield shells 40 and 68 are maintained in the same electric potential through a ground electrode of the substrate 10 to effectively prevent unwanted emission caused by a ground potential difference between connectors.

The present invention is to provide a delay correction circuit for a semiconductor tester which can decrease a circuit size and electric power consumption in a timing correction part. To achieve this goal, a variable delay element which corrects the phase difference stemming from the common parts of test stations is provided at an output of a waveform controller. At an output of a waveform output controller which generates the signal determining whether a signal should be applied to the test stations, flip-flops are provided which perform an inter-leave function. A gate circuit is provided which combines each unit of the inter-leave function based on the output signal of the variable delay element. An AND gate is provided which takes the logical AND between the output of the gate circuit corresponding to the test station and the output of the variable delay element. A variable delay element which corrects the phase difference stemming from each test station is provided at the output of the AND gate.

An image coding system and method thereof previously defines a plurality of combinations into a table. The table includes candidate values for quantizing steps and candidate values for upper limit values of space frequencies in correspondence with an image code size. The frequencies are coded into the pattern table on the basis of an error between the required code size, which is decided by the system performance, and required images. The generated code size is taken at the time of prediction coding between motion compensation frames. One combination of a quantizing step and upper limit values of space frequency are selected. The combination is coded from the candidate values depending on the image attribute and codes conforming to an international standard. The combinations are generated at a satisfactory coding efficiency. The coding efficiency is achieved by controlling the coding parameters depending on the image attribute and generated code size.

An electrical connector 10 has electrical contacts 30a, 30b arranged in cavities 40a, 40b of a housing 50. Electrical contacts 30a, 30b include contact sections 31 and termination sections 32a, 32b having plate sections 36 oriented perpendicular to a surface of the contact sections 31 and soldering termination members 37. When electrical contacts 30a, 30b are placed in the housing 50, a rear portion 34 of the contact section 31 can be bent due to the fact that cut-outs 47a, 47b corresponding to the rear portion 34 are provided in the inside walls of cavities 40a, 40b, thus allowing for elastic deformation of the rear portion 34. In addition, plate sections 36 have lugs 38 accommodated in grooves 55 formed in the housing 50. Because of resilience of the rear sections 34, the lugs 38 engage against bottom surfaces 56 of the grooves 55, thus determining the position of the soldering termination members 37.
摘要:
A method for separating a joined substrate type wafer, which wafer is composed of a pair of semiconductor substrates joined through an insulation film, utilizes dielectrics through simple processing steps. Trenches for separating a semiconductor substrate with dielectrics are dug from the surface of the substrate and a dielectrics film is deposited on the surface of the substrate including the trenches. Then poly-crystalline silicon is grown by CVD to a thickness of about 0.5 .mu.m, which is deep enough to fill the trenches. The process time for growing poly-crystalline silicon is shortened, and the processing step for removing the poly-crystalline silicon deposited on the unwanted areas is eliminated by growing the poly-crystalline silicon in the trenches but not on the crystalline surface of semiconductor regions based on the growth rate dependence of the poly-crystalline silicon on the crystallinity of the surface on which the poly-crystalline silicon is grown.

A sheet supplying apparatus supplies sheets one by one from a paper cassette to a transfer portion defined between a photosensitive body and a transfer charger in a housing. The sheet is picked up by rotation of a pair of feed rollers. The picked-up sheet is aligned by register rollers. The feed rollers are driven in synchronism with the operation of the register rollers.
