Title: Lock-up control device for torque converter
Inventor: WATANABE AKIRA
IPC: F16H59/18
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To change locking pressure with a desired dynamic characteristic by setting a target before-after differential pressure by a lock-up pressure intensifying/reducing command signal, and computing the command value by a before-after differential pressure filter making before-after differential pressure respond with a target dynamic characteristic to adjust the before-after differential pressure. SOLUTION: A lock-up pressure reducing part 8 performs pressure reducing control of differential pressure before and after lock-up on the basis of information from a coasting switch 6 and a lock-up part 7. In case of a transition state from driving to a coasting state, a lock-up state is checked, and in case of a locked state, lock-up target differential pressure dPr required in the coasting state is computed and substituted for dPi to be the input of a lock-up before- after differential pressure filter. Target differential pressure dPi is inputted by the lock-up before-after differential pressure filter to compute the differential pressure command value dP0 . The differential pressure command value dP0 is converted into a lock-up duty D and outputted to a lock-up solenoid 4. Locking pressure can therefore be changed with the desired dynamic characteristic of a designer.

Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous data from being written in memory cells of non-selection by raising potentials of bit line pairs according to voltages to be supplied from a ground terminal to word lines of inactivated states. SOLUTION: A clamping circuit 201 is provided with an NMOS transistor whose source and gate are respectively connected to data busses (I/O lines) 1 and a ground terminal GND and to whose drain a power source voltage is connected. When a write buffer 31 is of the output of a low level, the signal of the low level is transmitted to the I/O lines as it is. At this time, when arising from a zero level is present in a voltage to be supplied from the ground terminal GND to the gate of the clamping circuit 201, the level of the gate becomes high as compared with that of the source. Consequently, the NMOS transistor 201 is turned on by the order of the raising of the voltage to be applied by the ground terminal GND. Moreover, the low level on the I/O lines is also raised in accordance with the order of the raising of the voltage to be applied by the ground terminal GND.

Abstract: PURPOSE:To make electric connection between a conductive film and the outside sure by forming a part whose wettability to resist for patterning is decreased, at a part where a pattern is not formed on a conductive film deposited on the surface of a semiconductor manufacturing substrate. CONSTITUTION:A mask substrate 1 is formed by depositing a Cr film 3 as a conductive film on the surface of a glass substrate 2, and the upper surface of the film 3 is covered with resist 4 for patterning. Excepting a pattern forming region 1a, the other region 1b on the periphery of the substrate 1, where a pattern is not formed, is not coated with the resist 4, and an exposed part 3a where the Cr film 3 is exposed to the outside is formed. This exposed part 3a can be electrically connected with an earth pin 5. As to the exposed part 3a, a part of the film 3 is, e.g., compulsorily contaminated, thereby decreasing the wettability of the contaminated part to the resist. When a pattern is formed on the substrate 1 in this state, charge on the substrate 1 can be prevented by grounding the film 3 via the earth pin 5.
