A logic circuit is provided which includes a first multi-emitter transistor with its emitters coupled to a group of first input lines and a first transistor with its base coupled to the collector of said first multi-emitter transistor. A second transistor is also provided with its base coupled to the collector of said first transistor, said second transistor having a polarity opposite to that of said first multi-emitter transistor. A second multi-emitter transistor is connected with its base coupled to the collector of said second transistor and with its emitters coupled to a group of second input lines, and a third transistor is connected with its base coupled to the collector of said second multi-emitter transistor and with its collector coupled to an output line. The collector of said first multi-emitter transistor is coupled to the emitter of said second multi-emitter transistor in order to absorb minority carriers stored in the transistors. This feature significantly improves the circuit operating speed. A further feature is the provision of a logic circuit which is highly integrated and which consumes reduced amounts of electric power, while maintaining high-speed performance of the TTL circuit, by substituting a multi-collector transistor that reversely operates for an inverter portion of the TTL circuit.

A semiconductor integrated circuit device incorporating bipolar transistors and IILs comprises respective buried layers in a substrate and active regions. A buried layer formed in the IIL region has a larger Gummel number than that of a buried layer formed in the bipolar transistor region so that a leakage current to the substrate is prevented. A larger Gummel number of the buried layer is accomplished by increasing the impurity concentration or the thickness of the layer. The device structure allows an enhanced circuit packing density, while suppressing a leakage current to the substrate.

First and second oil flow passages are defined in a wall portion of a transmission casing. The first oil flow passage has an open end exposed to an interior of the casing. The second oil passage is connected to the first oil passage through a connection opening defined by the first oil passage. A separate pipe member has a predetermined end portion that is inserted into the first oil passage from the open end of the same. The predetermined end portion comprises a cylindrical portion having a fixed length; an end opening defined by an end of the cylindrical portion and exposed to the first oil passage; and an orifice opening defined by a side wall of the cylindrical portion. The orifice opening is blocked by an inner wall of the first oil passage when the connection opening takes a first position relative to the open end of the first oil passage, and exposed to the second oil passage when the connection opening takes a second position relative to the open end of the first oil passage. The second position is closer to the open end of the first oil passage than the first position is.

A resin composition is provided which comprises from 50 to 95% by weight of a modified ethylene-vinyl alcohol copolymer (C) obtained by reacting an ethylene-vinyl alcohol copolymer (A) with a monovalent epoxy compound (B) having a molecular weight of 500 or less, and from 5 to 50% by weight of a soft resin (F) that has at least one functional group able to react with a hydroxyl group and has a Young's modulus at 23° C., 50% RH of 500 MPa or less, wherein the soft resin (F) is dispersed with an average particle diameter of 0.1 μm or less in a matrix of the modified ethylene-vinyl alcohol copolymer (C). This resin composition is excellent in barrier properties and also in flex resistance and impact resistance at low temperature.

It is an object of this invention to provide a user-legible print result in consecutively printing a plurality of pages of images. To this end, it is checked whether there is continuity between data to be printed at the lower end portion of a page and data to be printed at the upper end portion of the next page. If there is continuity, a page break is inserted before the data at the lower end portion of the page, and an image of the data at the lower end portion is printed on the next page. Controlling a printing method in this manner makes it possible to prevent character split due to printing across pages and provide a user-legible print result.
摘要:
A bus bar has a lead portion and a bus bar portion which are integrally shaped. The lead portion is provided in such a shape that branches from the bus bar portion. A part of the lead portion forms a connection part directly electrically connected with a transistor electrode and a diode electrode by a connecting material such as solder. The thickness of the lead portion including the connection part is made smaller than the thickness of the bus bar portion. Accordingly, such an interconnection structure can be provided in which the electrode of the semiconductor device and the bus bar are electrically directly connected with each other and thermal stress at the connection part therebetween can be relieved.
