摘要:
A controller of an automatic transmission can be set to be in a first control mode and a second control mode for controlling a transmission gear ratio of the automatic transmission. The controller in the second control mode automatically changes the transmission gear ratio. The controller obtains an index value and upper limit speed of rotation speed of a transmission output shaft. The controller in the first control mode allows the transmission gear ratio to be changed when an operation member is operated to increase the transmission gear ratio and the index value is equal to or lower than the upper limit speed. The controller has a setting section that sets the upper limit speed. The setting section sets the upper limit speed based on vehicle acceleration when the controller is in the first control mode and the operation member is operated to increase the transmission gear ratio.
摘要:
A controller (30) of an automatic transmission (13) can be set to be in a first control mode and a second control mode for controlling a transmission gear ratio (SR) of the automatic transmission (13). The controller (30) in the second control mode automatically changes the transmission gear ratio (SR). The controller (30) obtains an index value and upper limit speed (Lim) of rotation speed (Nout) of a transmission output shaft. The controller (30) in the first control mode allows the transmission gear ratio (SR) to be changed when an operation member (22) is operated to increase the transmission gear ratio (SR) and the index value is equal to or lower than the upper limit speed (Lim). The controller (30) has a setting section (S13) that sets the upper limit speed (Lim). The setting section (S13) sets the upper limit speed (Lim) based on vehicle acceleration (AR) when the controller (30) is in the first control mode and the operation member (22) is operated to increase the transmission gear ratio (SR).
摘要:
A stacked electronic component comprises a first electronic component adhered on a substrate via a first adhesive layer, and a second electronic component adhered by using a second adhesive layer thereon. The second adhesive layer has a two-layer structure formed by a same material and having different modulus of elasticity. The second adhesive layer of the two-layer structure has a first layer disposed at the first electronic component side and a second layer disposed at the second electronic component side. The first layer softens or melts at an adhesive temperature. The second layer maintains a layered shape at the adhesive temperature. According to the stacked electronic component, occurrences of an insulation failure and a short circuiting are prevented, and in addition, a peeling failure between the electronic components, an increase of a manufacturing cost, and so on, can be suppressed.

After formation of an opening by exposing and development of the photosensitive surface protection film and adhesive layer which is formed on the circuit side of the semiconductor wafer, the semiconductor chips having a photosensitive surface protection film and adhesive layer thereon is fabricated by cutting individual chips from the semiconductor wafer. After the second semiconductor chip is placed over the first semiconductor chip up by the suction collet, the second semiconductor chip is bonded with the first semiconductor chip by the first surface protection film and adhesive layer. The suction side of the suction collet has lower adhesion to the second semiconductor chip than that between the now bonded semiconductor chips.

An adhesive layer of which thickness is over 25 μm and a dicing tape are laminated on a rear surface of a semiconductor wafer. The semiconductor wafer is cut together with a part of the adhesive layer by using a first blade of which cutting depth reaches the adhesive layer. The adhesive layer is cut together with a part of the dicing tape by using a second blade of which cutting depth reaches the dicing tape and of which width is narrower than the first blade. A semiconductor element sectioned by cutting the semiconductor wafer with the adhesive layer is picked up from the dicing tape, and is adhered on another semiconductor element or a circuit board.

This invention serves to suppress the deterioration of oil tightness of a valve after welding without any change in the direction of fuel injection even with deformation of a convex portion after welding of an injection opening plate to a valve seat, as well as without any variation in the direction of fuel injection due to welding variation. In this invention, in a fuel injection valve which has a valve body for opening and closing a valve seat, and receives an operation signal from a control unit to operate the valve body so that fuel is injected from a plurality of injection holes formed in an injection hole plate welded through a welded portion to a downstream side of the valve seat while passing through a gap between the valve body and the valve seat, said injection hole plate is formed at its central portion with a convex portion which is substantially axisymmetric with respect to a valve seat axis and which has a circular-arc shaped cross section, and said welded portion is also substantially axisymmetric with respect to said valve seat axis. In addition, inlet portions of said injection holes are disposed in an injection hole arrangement surface diametrically outside of said convex portion and diametrically inside of a valve seat opening inner wall which is a minimum inside diameter of said valve seat, and said injection hole arrangement surface is coplanar with a surface having said welded portion.

摘要:
A stacked electronic part comprises a first electronic part which is adhered onto a circuit board via a first adhesive layer and a second electronic part which is adhered onto the first electronic part via a second adhesive layer. An insulating resin having a filling viscosity of 1 Pa·s or more and less than 1000 Pa·s or a photo-setting insulating resin is filled in the spaces below first bonding wires which are connected to the first electronic part. Thus, the occurrence of bubbles resulting from the resin non-filled portions below the wires can be prevented. Besides, the first electronic part and the second electronic part are adhered via an insulating resin layer having an adhering viscosity of 1 kPa·s or more and 100 kPa·s or less. Therefore, the occurrence of an insulation failure, a short circuit or the like resulting from a contact between the bonding wires of the lower electronic part and the upper electronic part can be prevented.
