摘要:
A marine propulsion system comprising a push rod (50) for adjusting the pitch of propeller blades (34). The push rod (50) has a screw-threaded bolt (60) engaged with a nut (78). The nut (78) carries a bevel gear (84) by which the nut (78) can be rotated to cause the bolt (60) and therefore the push rod (50) to move longitudinally. The push rod (50) is connected to a claw with arms couple with pins (170). The pins (170) engage eccentric shafts (174) for unlocking a propeller base (190) so the base (190) can rotate around a transverse axis. The base (190) has an inclined surface which engages with an inclined surface defining an opening in the propeller's hub therefore locking the propeller blade (34) in position. The inclined surfaces are disengaged by rotation of the eccentric shaft (174) thus the propeller blades (34) can be rotated to adjust the pitch and than the inclined surfaces re-engage locking the propeller blade (34) in the pitch adjusted position.
摘要:
An integrated circuit is described that comprises a PMOS transistor and an NMOS transistor that are formed on a semiconductor substrate. A silicate glass layer is formed on only the PMOS transistor or the NMOS transistor; and an etch stop layer is formed on the silicate glass layer. Also described is a method for forming an integrated circuit. That method comprises forming a PMOS transistor structure and an NMOS transistor structure on a semiconductor substrate, forming a silicate glass layer on only the PMOS transistor structure or the NMOS transistor structure, and forming an etch stop layer on the silicate glass layer.
摘要:
Systems and methods for determining and sending a preferred of two electronic mail communications or messages (‘emails’) to a group to increase likelihood of its review. Information for conducting a test between two emails, referred to as A email and B email, is collected. The information may identify a particular group, and segments A and B of the group. The information may provide content for the emails and include differentiation information between the emails. Determination information on how to select one of the emails as the preferred email and when to select the preferred email may be collected. The information is used to send the A email to the segment A, to send the B email to the segment B, to determine the preferred email between the A email and the B email, and to send the preferred email to at least a portion of the particular group.
摘要:
Methods and systems for sending an email so recipients receive it at a selected time in respective time zones. Information about recipients may determine times zones. Information may include zip code, IP address, or identification of a server or service provider serving a recipient. Information may be based on a recipient's activity such as determination of a time zone in which more emails are received than any other, or having a highest weighted average (based on frequency of email receipt and recent history). The email is sent so recipients receive it at the selected time in the respective time zone. Recipients may be grouped by time zones. After sending the email to the recipients, open/click rates of the email by the recipients by the determined time zones may be determined and displayed on a time zone map.
