Filed: 1985-05-31
Abstract: PURPOSE:To improve a lead frame by providing a position mark which indicates the connecting position of bonding wiring with external leads, thereby preventing mounting bonding wirings from contacting with islands. CONSTITUTION:A semiconductor element 102 is mounted on an island 101, external leads 11 are disposed outside the island 101, and the element 102 and the leads 11 are connected therebetween by bonding wirings 103. The second bonding area of the (inner) leads 11 of a lead frame is formed with a position mark 12 of circular recess by coining at the center of the prescribed distance from the ends of the leads. Thus, it prevents the wirings 103 from contacting the island 101 to facilitate the extension of the wirings 103 of the lead frame.

Title: Shift operation control device for vehicle
Inventor: MOROTO SHUZO
IPC: F16H61/04
Filed: 1995-05-16
Abstract: PURPOSE: To perform smooth gear shift operation by a method wherein, in a neutral position, a cut signal from a clutch means is started, and when both a running signal exceeding a given speed and an accelerator ON signal are received, an engagement signal is transmitted from the clutch means regardless of a disengagement signal. CONSTITUTION: When skip gear shift is effected during running, a manual shift means 76 passes a neutral position in the middle of gear shift operation. But, in the position, an accelerator pedal 71 is stepped on once, the number of revolutions of an engine is increased and an accelerator sensor 72 is brought into an ON-signal state. A clutch means 6 is engaged, an increased engine output shaft is transmitted to the input shaft of a gear shifter 1 and the generation of a rotation difference between the input output sides of a speed change gear is reduced. Pedaling of the accelerator pedal 71 is released and the clutch means 6 is disengaged, and a manual shift means 76 is switched from a neutral position to a given speed. Since the clutch means is operated like a double clutch only through operation of the accelerator pedal, a gear shift operation is smoothly performed in any state.

Abstract: PURPOSE:To prevent the wasteful evaporation of a liquid holding an airtight chamber to high humidity, by providing the member for opening and closing the hole communicated with a nozzle surface in the airtight chamber of a capping means in a movable manner and closing the hole by moving the member at the retracted position of the capping means by gravitational action. CONSTITUTION:A cap roller 12 is rotated when a recording apparatus is used to detach a capping member 13 from the position of a nozzle surface 1e and the nozzle surface 1e is opened to the outside to perform recording. At this time, the capping member 13 is located at a retracted position and, because a roller 20 closes a communication hole 12c, a chamber 12b is made airtight to prevent the wasteful evaporation of a liquid 10. When the recording apparatus is not used, the cap roller 12 is rotated to the reverse direction to allow the capping member 13 to contact with the nozzle surface 1e and the capping member 13 is contacted with a head 1 under pressure and acts so as to cover the periphery of the nozzle surface 1e. At this time, because the roller 20 is moved to open the communication hole 12c, the vapor of the liquid introduced into the chamber 12b is introduced into the capping member 13 to hold the nozzle surface 1e to high humidity.
