Title: Resin sealed type semiconductor lead frame
Inventor: IWAMA NAOKI
IPC: H01L23/50
Filed: 1993-11-16
Abstract: PURPOSE:To enhance a depressed part of a lead frame in processing accuracy by a method wherein a plating layer is removed from the depressed part so as to keep the depressed part high in processing accuracy and a recessed part as deep as prescribed. CONSTITUTION:A tie bar 1, a die pad or a recessed part 2 in parallel with the die bar 1, and a depressed part 3 adjoined to both the die bar 1 and the recessed part 2 are all formed of a conductive metal thin plate by the use of a press die, whereby a prototype of a depressed type resin-sealed semiconductor device lead frame can be obtained. At this point, a dent a is produced at the end of the tie bar 1 due to a press die used in a pressing process. A silver plating layer 4 is deposited on the die pad 2 on which a semiconductor chip is mounted but not on the depressed part 3 where a conductive metal thin plate is exposed, and thus a depressed type lead frame is obtained. As mentioned above, a depressed part is not coated with a plating layer, so that a recessed part can be kept high in processing accuracy and as deep as prescribed.

Title: Binary encoding system
Inventor: KAWAI NAOKI
IPC: H03M1/12
Filed: 1987-11-13
Abstract: PURPOSE:To minimumize the error of a signal amplitude due to an erroneous bit by executing a binary encoding to be suitable for signal level distribution. CONSTITUTION:The binary encoding, except for a most significant bit, is caused to be a group according the number of a bit 1 in a binary code and these groups are arranged symmetrically toward both sides from a central value in the order of the small number of the bit 1. Then, in the group, the bit 1, except for the highest order bit, is arranged in the order to be nearly right closed or left closed and further, a different code is added to the codes of the both sides as the highest order bit. For example, by inputting a natural binary code (a) ot an Nbit to the address of an ROM1, a code (b) to be converted to a 'weighting order code' is obtained to an output. Then, the code (b) is used for transmission or a recording signal. The received or reproduced code (b) is returned to the natural binary code (a) again by an ROM2. Namely, by using the 'weighting order code', an influence due to a code error, in case that there is the error in information, can be decreased.

CONSTITUTION:Let a luminous quantity made incident in a photoelectric conversion element for a storage time T be LSIG and a signal charge generated in the photoelectric conversion element by the light be QSIG, then even when the illuminance is high and the luminous quantity LSIG is large, since the storage of the signal charge is implemented by the charge transfer element, the value of the signal charge QSIG at which the signal charge starts flowing to an overflow drain is larger than a conventional value and the range of linear function relation between the signal charge QSIG and the luminous quantity LSIG is established is widened. That is, the range from which an output signal in proportional to the luminous quantity LSIG of a light made incident in the solid-state image pickup device is widened in the drive method storing the signal charge in the charge transfer element Thus, at the time when the charge transfer element is in transfer operation and the signal charge is stored in the photoelectric conversion element, blooming is suppressed.
