Abstract: PROBLEM TO BE SOLVED: To provide a size inspection device for IC lead which can measure the flatness, etc., of the IC lead of a BGA(ball grid array), CSP(chip size package), etc., in a short time. SOLUTION: The size inspection device 1 for IC lead has a contacting-needle holder 4 which holds a plurality of lead contact needles 5 in the arranging pattern corresponding to IC leads to be measured. When the lower end 51 of each needle 5 is brought into contact with the corresponding IC lead 21, the upper end section 52 of the needle 5 is protruded from a plane of projection 6 by the amount corresponding to the height of the lead 21.

Title: Digital signal reproducing method
Inventor: KAWAMAE OSAMU
IPC: G11B20/18
Filed: 1990-11-28
Abstract: PURPOSE:To prevent the generation of an abnormal sound, etc., and to prevent the error correction by C2 parity by processing all of the data of one block including an erroneous block address as error data when an error is detected in the block address. CONSTITUTION:The error of the block address 5 and an ID code 6 can be detected by a parity code 7 but there is the probability of a missing in detection in the error detection of the simple parity degree. The missing in detection arises at a fairly high rate of the probability of the missing in detection if, for example, an 8-bit parity code is used. The deviation in order of the data is resulted if particularly the block address 5 is erroneous. Namely, a block deviation arises and such is the cause for the generation of the abnormal sound. If, therefore, the error is detected in the block address, all of the data of this block are outputted by adding the error codes thereto. The generation of the abnormal sound and the erroneous correction in the correction of the error detection by the C2 parity are prevented in this way.
