A knock control system which includes a knock control unit constructed of a transducer portion for detecting vibrations of an engine and converting the detected vibrations into an electric signal, and a knock signal processing unit for delivering a signal indicative of the occurrence of a knock in dependence upon a receipt of the knock signal from the transducer portion. The knock signal processing circuit controls the ignition timing of the internal combustion engine on the basis of the knock signal from the knock control unit. At least one of the transducer portion and the knock signal processing circuit unit of the knock control system is mounted on a portion of a distributor which has a fixing base portion at a part of the housing thereof.

To improve an anti-heat shock performance and an electric field concentration relaxation (an insulation performance) between a secondary coil and a center core, to attain a narrow diameter structure in an individual ignition type ignition coil and further to improve an assembling working of the ignition coil. The individual ignition type ignition coil is adopted to an engine having a plastic head cover. A secondary coil 3 is positioned at an inner side of a primary coil 5 and between a secondary bobbin 2 and a center core 1 a soft epoxy resin 17 is filled up. In the secondary bobbin 2, a secondary coil low voltage side is a potting side of the soft epoxy resin 17 and an inclination having a difference in an inner diameter is provided on the inner diameter in which the secondary coil low voltage side is formed large and secondary coil high voltage side is formed small. In the secondary bobbin, a thickness in the secondary coil low voltage side is formed thin and a thickness in the secondary coil high voltage side is formed thick. The soft epoxy resin 17 has a dent 17′ according to a compression molding and has a glass transition point Tg which satisfies a condition of [an allowable stress of the secondary bobbin > a generation stress at (from −40° C. to a glass transition point of an insulation resin)]. The secondary bobbin is formed by PPS and the primary bobbin is set to the primary coil at outer side of the secondary assembling body and under an assembling condition the winding is carried out.

This invention relates to an image forming apparatus including a developing unit which develops an electrostatic latent image formed on an image carrier by using a two-component developing agent containing polymerized toner. The developing unit includes a supply/convey member which conveys the two-component developing agent in the axial direction while agitating it and a toner density sensor which detects the toner density of the two-component developing agent. The toner density sensor is placed to be in a non-contact state with respect to the supply/convey member and oppose it with a gap of 0.8 mm or less. The diameter of the supply/convey member is set to 23 mm or more.

User information stored in a second server as a proxy authentification device is deleted from a first server performing authentification of the network connection. Accordingly, it is possible to easily and surely delete the user information stored in one of the plurality of second servers from the first server. That is, it is possible to delete user information stored in a server such as a proxy server acting for authentification in a short period of time.

A node is a signalling end point that handles a control signal of the common channel signalling system. Four IP-STPs are signalling transfer points that transfers the control signals. A node and four IP-STPs belong to a logical network A identified by a network identifier NI=0, and four IP-STPs belong to a logical network B identified by a network identifier NI=15. In the logical network A, only one signalling point code is allocated to the four IP-STPs. The control signal is transferred using the network identifier NI and signalling point code SPC.

An ignition apparatus is received in a plug hole which is formed by a cylinder head and a cylinder head cover of an internal combustion engine. A side core has a slit between two horizontally extending side wall ends. The side core is selected from a laminated sheet structure comprised of two grain oriented silicon steel sheets, each having a slit between two horizontally extending side wall ends, and the plural slits align at substantially the same position. The slit prevents a one-turn short of a magnetic flux of the side core. Thereby a predetermined secondary voltage more than an engine requirement secondary voltage is obtained. An ignitor reception portion has an independent and individual ignitor reception portion and an independent and individual coil reception portion, with the ignitor reception portion and the coil reception portion being combined.

An apparatus establishes a common signal channel with a flexible channel capacity for effective utilization of the total traffic capacity between two exchanges or stations which are interconnected by the common signal channel. A traffic detecting unit in one of the exchanges detects a traffic volume in the common signal channel between the exchanges. Based on the detected traffic volume, a channel capacity change determining unit determines whether a channel capacity to which the common signal channel is set needs to be changed or not and determines a new channel capacity to be established for the common signal channel if the channel capacity needs to be changed. If the channel capacity to which the common signal channel is set needs to be changed, a channel capacity change executing unit executes a change in the channel capacity to which the common signal channel is set based on the established new channel capacity.

A swing analyzing device comprising swing practice equipment such as a golf club, wherein acceleration sensors are arranged on the shaft or on an axis of the swing practice equipment, or near the axis, and a dynamic quantity representing a movement of the shaft, such as an angular velocity, angular acceleration, and angle of the shaft, is calculated from an output of the acceleration sensors. The acceleration sensors are preferably arranged on the shaft in a spaced apart relationship so that directions of detecting acceleration substantially coincide with an axis of the shaft. A further acceleration sensor can be arranged on the shaft so that a direction of detecting acceleration forms a certain angle with an axis of said shaft.
