In an industry in which egos frequently are as large as the products are small, Adam Osborne may take the prize for each. Mr. Osborne is the founder and president of the Osborne Computer Corporation, which makes a portable, mass-marketed personal computer that is quickly gaining popularity. Mr. Osborne is also an uninhibited commentat or on the personal computer industry and is quick to find fault with his competitors andto boast of his own accomplishments. ''I liken myself to Henry Ford and the auto industry,'' he said during an interview in his office, south of Oakland. ''I give you 90 percent of what most people need.

International Nearly 200 Poles were arrested in Poznan, a city in western Poland, when they tried to hold a demonstration to protest martial law, the Warsaw radio said. In Warsaw, a series of symbolic protests urged by the Solidarity trade union failed to take place. (Page A1, Column 6.) Israel will oppose more arms sales to Jordan by the United States. Israel's Cabinet Secretary, Aryeh Naor, said that Israel ''won't sit in silence'' over the potential change in the Middle East balance of power in a response to Defense Secretary Caspar W.

France's Socialist Government began taking control of a huge slice of the country's privately owned industry and banking this weekend. When the program is completed, probably this summer, more industry will be under Government control than in any other country in Western Europe. State-owned companies will employ roughly 23 percent of the work force, and the Government will control 75 percent of all bank deposits and loans as well as 29 percent of the country's industrial production. For the Socialists, the program is the cornerstone of a high-risk strategy for breaking out of the economic recession afflicting all the major Western industrial economies.

The continuing differences between Secretary of State Alexander M. Haig Jr. and Defense Secretary Caspar W. Weinberger seem so obvious to some ranking officials that they say the effective management of the Reagan Administration's foreign policy is being threatened. It has been clear for some time that the disagreements between the two secretaries were more than the usual State Department-Pentagon rivalries, despite repeated efforts by both men and their aides to gloss them over publicly. But in recent months, with the Administration deeply involved in trying both to maintain a cease-fire in the Middle East and to keep the Western alliance together in the midst of the Polish crisis, these Haig-Weinberger differences appear more acute. White House Frowns on Conflict Because the White House has made it clear that it does not like to see any public debate among its top aides, Mr. Haig and Mr. Weinberger have been under pressure to play down the intensity of the conflict. Mr. Haig, who lacks Mr. Weinberger's longstanding personal friendship with the President, has in particular sought to avoid any public clash. However, when pressed today about public disagreements on how hard to press the Soviet Union, Mr. Haig acknowledged on the ABC News television program ''This Week'' that the dispute existed.

Congress shows little interest in abolishing the Department of Energy, a step that has long been sought by the President. Key House and Senate members object to the move, and many others find it politically unappealing. (D1.)
