Filed: 1984-11-07
Abstract: PURPOSE:To easily prevent oil mist generated in an oil tank from leaking outside of the oil tank, by providing a viscous seal section by means of a viscous fan, between a rotary member and a stationary section. CONSTITUTION:A narrow gap is defined between the outside of a thrust bearing metal 1 journalled by a bearing 2 within oil and a seal 4b, and is used as a viscous seal section 9.

Title: Method of testing integrated circuit
Inventor: KURIHARA MASAHIRO
IPC: G01R31/28
Filed: 1987-09-21
Abstract: PURPOSE:To enable the testing of an integrated circuit being divided into function blocks, by making a signal terminal in a normal operation mode serve in common as a test terminal in a test mode to use a test signal in a time division manner. CONSTITUTION:When testing a block 1, a contact of a selector switch SW is opened or closed to turn a test timing signal T1 to H or a test timing signal T2 to L. An input signal to the block 1 is given as signal inputted direct from a terminal A and test signal inputted at a terminal D. With the inputting of the test signal, in a normal operation mode, a situation is established as equivalent to that when a block 2 is operated and then, an output thereof is inputted into the block 1. Then, an output signal from the block 1 is outputted direct at a terminal B because the signal T2 is H. Thus, in a test of the block 1, an output of the block 1 can be tested directly as this eliminates the operation that the block 2 is run and an output thereof is inputted into the block 2 to test.
