The American semiconductor industry - fast-growing, prosperous and free of Government control - has stood in stark contrast to some older industries, including steel and automobiles, which have suffered from foreign competition and aging factories. Such factors have forced those industries to seek Government help. Now, however, the semiconductor industry is also appealing to Washington for help in competing with the Japanese and in investing in new equipment. It is mounting a campaign for freer trade and tax incentives.

The Supreme Court, ruling in two unrelated murder cases, today significantly expanded the constitutional protection against self-incrimination. The Court ruled in one case that a murder defendant must be given the right to remain silent when questioned by a psychiatrist who might later testify for the prosecution that the defendant was ''dangerous'' and should be put to death. That decision, in which the Court was unanimous although divided in its reasoning, has the immediate effect of invalidating the death sentences of 30 inmates in Texas. The second decision, also unanimous, held that once a criminal suspect has invoked his right to have a lawyer present during questioning, he cannot later be regarded as having waived that right unless he initiates further conversations with the police.

Italian voters today overwhelmingly rejected a proposal for the repeal of a liberal abortion law in spite of a determined campaign by the Roman Catholic Church and an antiabortion movement linked to the governing Christian Democratic Party. WIth 97 percent of the votes counted, the repeal had been rejected by 20,839,824, or 68 percent, with 9,905,350 votes in favor. The margin was far higher than even the most optimistic defenders of the law had expected.

Two small pipe bombs similar to one that killed a man at Kennedy International Airport on Saturday were found yesterday on Manhattan's East Side. Both were safely removed and no one was injured. The bombs were found at the United States Mission to the United Nations and the Honduran Consulate. Authorities said the bombs apparently were sent through the mail over the weekend by the same Puerto Rican terrorist group that had left three other bombs at the Pan American World Airways terminal at Kennedy Airport on Saturday and Sunday, including one that blew up, killing a 20-year-old airport worker. Police investigators, meanwhile, said they had found a witness who described in some detail a man who ran from a restroom in the terminal shortly before the fatal blast and had warned the witness to ''keep her mouth shut'' about him.
