There is provided a positive photoresist composition capable of forming a pattern with excellent resolution, excellent resistance to reflection off the substrate, and excellent perpendicularity. The positive photoresist composition comprises (A) an alkali-soluble novolak resin in which a portion of the hydrogen atoms of all the phenolic hydroxyl groups are substituted with 1,2-naphthoquinonediazidesulfonyl groups, and (B) a dissolution promoter represented by a general formula (b-1) and/or a general formula (b-11) shown below.

A means for increasing development velocity of a positive photoresist composition is provided which contains a photosensitive novolak resin formed by replacing some hydrogen atoms within those of all phenolic hydroxyl groups of alkali soluble novolak resin by 1,2-naphthoquinonediazide sulfonyl group. This means is positive photoresist composition and a formation method of a resist pattern using the composition which contains (A) a photosensitive novolak resin formed by replacing some hydrogen atoms within those of all phenolic hydroxyl groups of alkali soluble novolak resin by 1,2-naphthoquinonediazide sulfonyl group, which is dissolved in (B) propylene glycol alkyl ether acetate.

A DC power supply system and a control method, which can continue charging of a storage battery with a constant current even if an assist current is needed due to, for example, overload during charging of the storage battery and can suppress a current output from the storage battery as much as possible. In a power supply system, when a charger operates at a potential of an output voltage smaller than the potential of the output voltage of a rectifier during charging of the storage battery, the output current of the charger is controlled so that a charging current Ie supplied from the charger to the storage battery is kept at a predetermined value, and when a load requires a current larger than the current supplied by the rectifier during charging of the storage battery, the potential of the output voltage of the rectifier is reduced smaller than the potential of the output voltage of the charger by a current drooping operation, and the diode is electrically connected, the output current of the charger is controlled so that the charger outputs the assistant current Ic supplied toward the load while the charging current Ie is kept at a predetermined value.
摘要:
A digital broadcast receiver includes an operation mode manager that switches an operation mode to a first mode in which a function is implemented by the downloaded application or a second mode in which a function is implemented by the pre-installed application, and a key delivery module that delivers the key code received from the remote control to the downloaded application or the pre-installed application. When the receiver is in the first mode, the key delivery module delivers the received key code to the downloaded application if the received key code is a key code for the first mode, and delivers the received key code to the pre-installed application if the received key code is a key code for the second mode. When the receiver is in the second mode, the key delivery module delivers the received key code to the pre-installed application.

A video decoding and outputting apparatus includes: (a) a receiving means for receiving a digital broadcast; (b) a restoring means for restoring video data and information related to the video data from the digital broadcast received by the receiving means; (c) a viewing restriction information extracting means for extracting viewing restriction information from the related information restored by the restoring means; (d) a video converting means for converting the video data restored by the restoring means into an analog video signal; and (e) an outputting means for inserting the viewing restriction information extracted by the viewing restriction information extracting means into the analog video signal converted by the video converting means, for output.
摘要:
An exhaust muffler comprising an outer cylindrical body, front and rear end plates mounted on each end of the outer cylindrical body, porous plates fitted on the insides of the outer cylindrical body and each of the end plates, and partition plates for dividing the internal space of the outer cylindrical body into several chambers, wherein when joining the component parts with each other, three or four component parts are superposed via their joint portions each on the other and integrally joined by laser beam welding so as to obtain a reduction of welding steps and minimize the thermal influence in the manufacturing process while ensuring an air-tight condition of the partitioned chambers. When an exhaust pipe and tail pipe are connected to the end plates, respectively, they are laser beam welded to the end plates in a superposed fashion. Alternatively, the outer cylindrical body is formed in a multiple-layered construction with inner and outer panels which are so formed integral with each other as to squeeze or press inwardly, when assembling, an internally installed unit over its fill periphery, thereby not requiring particular measures for fixedly securing the internally installed unit to the outer cylindrical body. Preferably the outer cylindrical body and end plates are formed on an aluminum-plated or a stainless steel plate, thereby dispensing with a coating after welding.
摘要:
An edge protector for an electrolysis electrode onto which a thick-electrodeposited copper product is deposited for producing an electrolytic copper product, has an outer surface shape in the central portion thereof which reduces the thickness in that portion to improve uniformity of cooling, and thereby reduce stress cracking as a result of the reduced buildup of thermal stresses. The outer surfaces may be inclined planes or suitable curved shapes that converge from an outer jaw toward an inner jaw. In one embodiment an edge protector is taught such that its top end is angled downward from its center outward at an angle of less than twenty degrees to prevent creation of sharp edges and difficulty in removal. A spreader bar has a shape which enables clamping of the edge protector onto an electrolysis electrode without excessive expansion of the outer jaw, thereby lengthening service life, and easing installation. Both a hollowed and a tapered spreader bar are taught for end insertion.
