Title: Slip control device for vehicle
Inventor: HOSODA KOJI
IPC: B60W10/18
Filed: 1989-09-28
Abstract: PURPOSE:To maintain proper acceleration and ensure the stability of a vehicle for the change of a road surface mu value by delaying the operation of slip control when the mu value immediately prior to the detection of a large slip value is large. CONSTITUTION:A control unit UTR performs engine control via the control of a brake and the motor 106 of a throttle opening adjustment mechanism 44 in controlling a slip. When an accelerator throttle valve is not wide open and the slip control is not under way, the unit UTR judges whether the slip value S of a drive wheel is equal to or more than a target value SET for an engine. If YES, the unit UTR judges whether a road surface value mu immediately prior to the detection of a slip value equal to or above SET is larger than the predetermined value mu0. If YES, the slip control is prohibited. Also, after the predetermined time, a slip flag showing the slip control under way is set to 1, and a lower limit control value SM is set, thereby performing the brake control.

Filed: 1999-09-08
Abstract: PROBLEM TO BE SOLVED: To improve the welding efficiency without developing the lack of fusion by making a welding electrode oscillate along a bevel wall and a welded bead surface of a pre-welded layer. SOLUTION: The V bevel is arranged between two pieces of thick steel plates 10a, 10b and the welding layer is divided into plural layers and a vertical multi-layer welding is executed with an electro-gas welding method. Since the route w1 of the welding electrode in a primary layer is oscillated along the bevel walls 1a, 1b of the primary layer, the route is formed in triangle shape. Since the route w2 of the welding electrode in a secondary layer is oscillated along the bevel walls 2a, 2b and the bead surface 1c of the primary layer, the route is formed in trapezoidal shape. The route w3, w4 of the welding electrode in a ternal layer and a quantenary layer are formed in trapezoidal shape, too.  In the oscillating route of the welding electrode, at the cross points between the bead surfaces of the pre-welded layers and the bevel walls, i.e., at the temporary stopping points A, B, C, D, E, F, G, it is desirable that the welding electrode is temporarily stopped or the shifting speed is reduced or the welding current is increased.

Title: Ink jet recorder
Inventor: SATO EIICHI
IPC: B41J2/045
Filed: 1985-11-15
Abstract: PURPOSE:To eliminate interference between heads and record with high quality, by correcting the magnitude of a driving signal supplied to an ejecting energy generating means, according to the magnitude of a driving signal supplied to other ejecting energy generating means. CONSTITUTION:The pressure generated at the time of driving and the amount of an ink ejected are substantially proportional to each other, and an interference pressure delta appears directly as a variation in the amount of the ink ejected. When signals A-1-A-n for determining driving amounts for nozzles are supplied from driving signal sources in driving circuits for converting elements 3, a voltage corresponding to the interference pressure delta generated according to the driving amounts for adjacent ones of the nozzles is subtracted from a normal voltage by a subtracting circuit 9-1 to determine a peak value, and a driving pulse thus corrected in voltage is generated by a switching circuit 9-2. A driving voltage can be corrected by appropriately selecting resistors R-1-R-k according to a correction quantity, whereby the ink can be ejected in an appropriate amount.
