Abstract: The present invention relates to a method for producing music plate of music box, and more particularly to a music plate production method that can increase yield rate of music box, which includes a roll finishing step, a punch press step, a heat treatment step, a cut-off step, a chamfering step, and a valve needle formation step. The roll finishing step rolls steel material into continuous and wavy sheet metal with different thickness; the punch press step utilizes a punch press machine to punch and cut out a plurality of grooves on the trenches of the sheet metal beforehand and these grooves are used as the guiding lines for a grind cutter to carry out a cutting during the valve needle formation step. By means of the grooves cut beforehand on the trenches of the sheet metal serving as the guiding line for cutting, the grind cutter just need to proceed cutting along the grooves while cutting the sheet metal. Therefore, the occurrence of defective product arising from different width of valve needle won't be caused. Thus, the yield rate is increased. Moreover, by cutting sheet metal at the thickest portion only, the cutting process can be also conducted in a much more convenient way.

Title: TTL-to-CMOS input buffer circuit used for power dissipation reduction
Inventor: LI HUNG-DA
Filed: 2004-06-18
Abstract: A TTL-to-CMOS input buffer circuit used for power dissipation reduction is disclosed, which can stabilize the buffer stage input/output voltage logic conversion point for the purpose of power dissipation reduction when the power voltage, semiconductor process, and temperature (PVT: process, supply voltage, temperature) change. In order to stabilize the logic conversion point of the input buffer stage, the present invention adds a bias device to generate a negative feedback control signal for being applied to the input buffer stage in order to control and modulate the input buffer stage. Furthermore, in order to monitor the logic conversion point of the input buffer stage, the present invention duplicates the first stage (i.e. input stage) of the input buffer stage circuit into a first stage (i.e. copied input stage) of the new bias device. A comparator is installed in the new bias device as a second stage in the bias device. This comparator performs comparison and control duties on the copied input stage, and uses the compared result to produce a bias feedback signal (BIAS) in order to monitor and modulate this input buffer device. Thus, the input/output voltage logic conversion point of the buffer device becomes stable in order to avoid causing an excessive difference between the low-to-high level transmission time (tLH) and the high-to-low level transmission time (tHL) in this buffer device, as well as deterioration of the noise margin of the high/low levels. Under serious conditions, these defects will cause erroneous signal conversion which leads to defects and limits, such as disabling of the whole CMOS circuit. Thus, the invented device can ensure the normal operation of the whole CMOS circuit. In addition, with the special design of this invention, the transistors can be respectively connected in series and in parallel for forming a structure of transistor combination in order to provide the equivalent width and length (W/L) ratio, thereby enabling the buffer circuit of this invention to achieve the function and goal of having a logic conversion point with high stability and reducing the static power dissipation.
