摘要:
In an ignition system for an internal combustion engine, a signal generator generates a given ac signal in synchronism with the rotation of the engine and a waveform reshaping circuit reshapes the waveform of the ac signal from the signal generator thus generating a pulse signal. An ignition timing control circuit is responsive to the pulse signal from the waveform reshaping circuit to control the timing of ignition of an ignition coil in which a primary current is switched on and off in accordance with the pulse signal.

In an interchangeable camera lens having a cam sleeve rotatable by a sliding movement of an operation ring, the cam sleeve comprises a first cam slot for moving lens of variable magnification and a second cam slot for moving lens of focus compensation. The first cam slot has a first rectilinear portion inclined at a predetermined angle with respect to the axial direction of the cam sleeve and a second portion angled from the front end of the rectilinear portion toward the circumferential direction thereof. The second cam slot has a first arc-shaped portion and a second portion angled rearwardly from the end of the arc-shaped portion.

Modified polyolefin having high adhesion strength and less irritating odor during processing is obtained by reacting unsaturated carboxylic acid or its anhydride grafted polyolefin with a bifunctional compound having alcohol groups or amine groups. Preferable unsaturated carboxylic acids are maleic acid, and endobicyclo-[2,2,1]-5-heptene-2,3-dicarboxylic acid. Preferable bifunctional compounds are ethylene glycol, 1,4-butanediol, 1,6-hexanediol, glycerine, ethylene diamine, 1,3-diaminopropane m-phenylene diamine, etc.

Techniques described herein generally relate to processing data sets. The data sets can each include multiple indexed data values that can be partitioned into first and second portions. Each data value in each of the first portions of the data sets may have a greater magnitude than each data value in each of the second portions of the data sets. The first portions and second portions of the data values can be further processed by either different processors, or different processor cores as may be desirable.

This invention constructs within the LAN a private area network (PAN) which is configured by terminal devices (personal computers and the like) of a specific group, is hardly influenced by the LAN traffic, and has high security. For this purpose, a PAN server which manages the communication route between specific terminals is installed within the LAN. The PAN server sets the communication route of each terminal device as label information, and causes switches and terminals to set pieces of label information generated for them. When the frame of data from a given port of each connection switch contains information representing PAN communication, the connection switch outputs the data to only a port specified by routing label information described in the frame.

The present invention aims at a tractor which can easily perform an assembling operation and a maintenance operation of a PTO transmission mechanism. According to the present invention, a PTO casing which incorporates a PTO transmission mechanism therein is detachably mounted on a rear portion of a transmission casing and, at the same time, the PTO casing is mounted in a state that a front portion thereof is housed in the inside of the transmission casing. By mounting the PTO casing which incorporates the PTO transmission mechanism therein on the rear portion of the transmission casing in this manner, it is possible to easily perform the assembling operation and the maintenance operation of the PTO transmission mechanism. Further, by mounting the PTO casing in a state that the front portion thereof is housed in the inside of the transmission casing, it is possible to miniaturize the transmission casing (make the transmission casing compact).
