摘要:
An image forming apparatus has an image forming unit together with a fixing unit which uses two rotating members to form a nip in which the recording material with an unfixed image is fed. A driving unit drives the rotatable fixing members and a flywheel is used for increasing an inertial force of that drive, there also being a connecting device which selectively connects the flywheel with the driving unit together with a switching device that switches operation of that connecting device in accordance with the type of recording material being used or the density of the image to be printed.

A miniature zoom lens has, sequentially from an object side, a first lens group G1 having negative refractive power, a second lens group G2 having positive refractive power and including a diaphragm, and a third lens group G3 having positive refractive power. The first lens group G1 is formed from a single negative lens L1. The second lens group G2 is formed from, sequentially from the object side, a single positive lens L2 and a single negative lens L3. The third lens group G3 is formed form a single positive lens L4. The first lens group G1 is immovable and the second lens group G2 and the third lens group G3 move in an optical axis direction at variable power. The miniature zoom lens provides a large zoom ratio while keeping a constant total length.

A SRAM of complete CMOS type having its memory cell composed of six MISFETs, in which a pair of local wiring lines for connecting the input/output terminals of CMOS inverters are formed of a refractory metal silicide layer formed over a first conducting layer constituting the individual gate electrodes of the drive MISFETs, the transfer MISFETs and the load MISFETs of the memory cell and in which a reference voltage line formed over the local wiring lines is arranged to be superposed over the local wiring lines to form a capacity element.Moreover, the capacity element is formed between the local wiring lines and the first conducting layer by superposing the local wiring lines over the first conducting layer.Moreover, the local wiring lines are formed by using resistance lowering means such as silicification. In addition, there are made common the means for lowering the resistance of the gate electrode of the transfer MISFETs and the means for forming the local wiring lines.

A resin composition for use in a hybrid lens containing a radical polymerizable monomer and a silane coupling agent. A specified di(meth)acrylate compound and a specified mono(meth)acrylate compound are used preferably as the radical polymerizable monomer. A hybrid lens molding die in which a glass lens base material and a glass mold of transferring an aspherical shape are opposed to each other is used, a resin composition for use in the hybrid lens is filled between them and UV-rays are irradiated from both sides of the glass lens base material and the glass mold to manufacture a hybrid lens in which the resin layer is bonded on the glass lens base material. A high performance hybrid lens having a resin layer of large thickness, with a large localized thickness and capable of increasing the aspherical quantity can be manufactured by the method.

A sheet processing system comprises a plurality of sheet processing devices, a primary sheet conveyance path, a secondary sheet conveyance path, and a controller which controls the sheet processing devices. The controller uses the primary sheet conveyance path to execute one job, and uses the secondary sheet conveyance path to execute another job in parallel with that one job.

A user sets n=0, his mail account A and password S, then computes V.sub.0 =E(A,S), W.sub.0 =E(A,V.sub.0), V.sub.1 =E(A,A.sym.1), W.sub.1 =E(A,V.sub.1) and M.sub.0 =E(W.sub.1, V.sub.0), and initially registers W.sub.0, W.sub.1, M.sub.0 and A by e-mail in a mail server. At a visiting site the user sends a service request and A to the mail server form an arbitrary terminal connected to the Internet, and the mail server reads out the authentication session number n corresponding to the identifier A and sends it back to the user. The user computes V.sub.n-1 =E(A,S.sym.(n-1)), V.sub.n+1 =E(A,S.sym.(n+1)), W.sub.n+1 =E(A,V.sub.n+1). V.sub.n =E(A,S.sym.n) and M.sub.n =E(W.sub.n+1, V.sub.n) and sends V.sub.n-1, W.sub.n+1 and M.sub.n to the mail server. The mail server computes E(A,V.sub.n-1) and E(W.sub.n, V.sub.n-1) and if they agree with preregistered W.sub.n-1 and M.sub.n-1, respectively, the mail server accepts the user as valid and sends a mail message of the user.
摘要:
There is provided a technique capable of reducing the electrode resistance by widening the effective area of an electrode in a cell for a standard potential supply connected to the memory cell. There is also provided a technique capable of reducing the memory cell area by reducing the area necessary for separation between the electrode in a cell for the standard potential supply and adjacent other electrodes. Two transfer MOS transistors of a first conductivity type and two driver MOS transistors are provided. A conductive layer for fixing the source potential of the driver MOS transistors to standard potential is so disposed above the transfer and driver MOS transistors as to the wholly cover the memory cell. Separation is carried out by using a photo-mask having an optically transparent substrate provided within the same transmissive portion with a pattern of a plurality of so-called phase shifter regions for inversion of the phase of transmitting light.

A fuel supply device of a gas turbine engine is provided. The fuel supply device includes a fuel divider which divides fuel supplied from a collecting fuel passage to feed the fuel to a pilot fuel passage and to a main fuel passage. The fuel divider includes a movable member which is movable according to fuel pressure at the fuel entrance and opens and closes pilot ports and main ports according to a distance of the movement of the movable member. When the fuel pressure at the fuel entrance is not higher than a predetermined value, the fuel is supplied only to the pilot fuel passage, while when the fuel pressure at the fuel entrance is higher than the predetermined value, the fuel is supplied to the pilot fuel passage and to the main fuel passage.
