In a voice data processing method and device detecting a pitch from history data during a packet loss and generating compensating data thereof, input signal data is decoded in a normal mode, a calculation of a normalized cross-correlation in coarse search used for a pitch detection is repeated by a predetermined frequency of loops within a required frequency of loops, based on history decode data, a peak value of a normalized cross-correlation obtained by the calculation and a delay data value corresponding thereto are held, and fine search is executed by repeating the calculation of the normalized cross-correlation in the coarse search by a remaining required frequency of loops, by using the peak value of the normalized cross-correlation and the delay data value in a packet loss mode, thereby generating compensating data.

A CODEC has a DSP which can consecutively execute a plurality of algorithms without restriction of a memory capacity. The DSP performs an encoding/decoding operation on a digital signal. A program memory stores a program divided into a plurality of block programs, the program being stored on an individual block program basis. A data memory stores a set of data used for executing each block program stored in the program memory, the set of data being divided into a plurality of data blocks and stored on an individual data block basis. A program executing unit executes each block program stored in the program memory by using a corresponding data block stored in the data memory. A program changing unit obtains a new block program from an external device each time execution of one of the block programs by the program executing unit is completed so as to store the obtained new block program in the program memory.

In an exhaust gas after-treatment apparatus (30) including a particulate filter (32) that receives as exhaust gas having passes through a catalyst converter (31) and traps particulates in an exhaust, injectors (6 through 9) used for a post fuel injection to activate the catalyst converter (31) and a filter control unit (36) that performs pest fuel injection control, the filter control unit (36) includes a determination portion that determines whether a post fuel injection operation should be started, and a calculation portion that calculates an integration value of a fuel injection amount after the post fuel injection operation is started in a case where the post fuel injection operation is started in responding to the determination portion. The post fuel injection operation is stopped when the integration value has reached a specified value. It is thus possible to appropriately perform the post fuel injection control to activate the catalyst converter.

A thermal printing apparatus has a pair of transporting rollers for transporting a medium to be printed, a head angle member which holds a thermal head at right angles to a direction of transporting the medium transported by the pair of transporting rollers and which is pivotally supported at one end thereof, and a device for pivoting the head angle member so as to move the thermal head towards and away from the medium. The apparatus further has a shaft moving device which moves a shaft for mounting thereon the head angle member depending on a thickness of the medium.

The exhaust manifold gasket according to present invention consists of a pair of beaded plates provided with beads extending along the circumferences of exhaust holes therein, and a piled plate assembly inserted between these beaded plates. The piled plate assembly consists of a pair of flat plates, and a refractory sheet member disposed between these flat plates and containing a core plate therein. The refractory sheet member is formed out of a material having a high thermal resistance, excellent heat insulating characteristics and a high compression resiliency at a high temperature, such as a mica material. Accordingly, this exhaust manifold gasket has an improved compression resiliency at a high temperature and an improved sealability at a high temperature, and is capable of properly cutting off the transfer of heat.

This invention discloses the method of manufacturing metallic gaskets which are properly prestressed by a load which is determined according to a stress calculation. In the process of applying prestresses to the gaskets, a die formed to a thickness smaller than the thickness of the metallic gasket material--which has a bead portion and is coated with resin such as a fluoroelastomer--is placed close to and surrounding the outer circumference of the metallic gasket material or inside the holes formed in the metallic gasket material. Then, the tension side of the bead portion of the metallic gasket material is prestressed by a stress greater than a specified stress that will occur when the metallic gasket is used.
