摘要:
In a method of manufacturing a semiconductor device having an LDD structure, source gases for generating plural types of impurity ions exhibiting different molecular weights and different projected ranges in a target during impurity implantation are supplied to a plasma space, ionized, accelerated with a voltage, and implanted in a semiconductor region on the target substrate. In the case of manufacturing a top-gate transistor, a gate electrode on the semiconductor region has a sufficient thickness to serve as a mask. In the case of manufacturing a bottom-gate transistor, a mask and a resistor are used. An implantation angle is set to an optimum value as desired. Thereafter, the impurity is activated as desired. Thus, the semiconductor device having the LDD structure is manufactured by a single step of impurity implantation.

A method of manufacturing a rubber coated fabric for a tire which includes a weft cutting step of cutting a weft of the rubber coated fabric base substance using a cutting device at a cut pitch Cp of two to five times an arrangement pitch P of a warp. The cut ductility of the weft is set between 5 and 20%. The cutting device utilizes first and second rollers in which the peripheral protrusions and the peripheral grooves are alternately formed. Groove widths W1 and W2 of the peripheral grooves of the first and second rollers are set between 2.0 and 5.0 mm, protruding widths T1 and T2 of the peripheral protrusions of the first and second rollers are set to 0.25 to 0.5 times the groove widths W1 and W2, and the insertion depths h1 and h2 of the peripheral protrusions to the peripheral grooves are set between 2.0 and 4.0 mm.

In assembling at least one metal frame in abutting supporting relation to a diaphragm to form a diaphragm assembly for an electro-acoustic transducer, for example, as in a microphone or headphone, the diaphragm, which may be an electret, is formed at least in part of a thermoplastic resin so as to provide the latter at each surface of the diaphragm which, in the abutting supporting relation, is engaged by a surface of a metal frame, and the frame or frames and the diaphragm are pressed together in the desired abutting supporting relation while each metal frame is heated so that heat is transmitted through the latter to melt the thermoplastic resin at the engaged surfaces of the diaphragm and frame or frames, whereupon the heating of the frame or frames is halted so that the thermoplastic resin hardens to bond together the diaphragm and frame or frames in the desired abutting supporting relation.

According to a method for manufacturing a pneumatic tire of the present invention using a rigid core, high-speed durability may be improved. The present invention comprises manufacturing a green tire in which the green tire is manufactured by adhering tire component members in sequence onto the rigid core. The manufacturing of the green tire comprises forming a band ply in which a band forming member is spirally wound on the rigid core to form the band ply, the band forming member being configured by a band cord, or a narrow band-shaped strip coated with a topping rubber. In the formation of the band ply, the bend forming member is heated to a temperature of above 100 deg. C. while being wound spirally with the bend forming member being extended by at not less than 0.5%.

An information processing apparatus/method employs error detection or correction to encode information to be distributed in a description format used in a multimedia network in which the error detection or correction encodes at least a portion in the header in the information to be distributed with higher redundancy than the entity in the information to be distributed. The encoded information to be distributed in a broadcast signal is multiplexed and transmitted. Alternatively, the information processing apparatus/method may involve: transmitting a portion of the header in the information to be distributed at least a plurality of number of times while the entity in the information to be distributed is transmitted; and/or transmitting a plurality of kinds of information as an entity in the information to be distributed, and using different error detection or correction ability in correspondence with the kind of information. The information processing apparatus/method may also involve inputting information data, and a check code for correcting an error of the information data, detecting the error state of the information data, setting an allowable error state of the information data, and controlling processing for the input information data in accordance with results in the setting step and the detection step.

A motorcycle tire comprises: a toroidal carcass comprising two carcass plies of cords arranged at an angle of from 20 to 80 degrees with respect to the tire circumferential direction; and a band comprising at least one ply of at least one helically wound cord disposed radially outside the carcass. The band cord is made of steel filaments of 0.08 to 0.20 mm diameter twisted together into a L×M×N structure. The band cord has a low tensile elastic modulus range and a high tensile elastic modulus range, wherein an inflection point between the low tensile elastic modulus range and the high tensile elastic modulus range lies between 2% elongation and 7% elongation of the cord, and a tensile force required to cause 2% elongation of the band cord is not more than 60 Newton.
