Title: D/a converter
Inventor: TAGAMI SHIGEO
IPC: H03M1/82
Filed: 1993-08-20
Abstract: PURPOSE:To provide a D/A converter capable of obataining a PWM wave by a low frequency clock while suppressing the generation of secondory distortion due to PWM and the generation of analog-like distortion due to dullness of a waveform, overshooting, and so on. CONSTITUTION:In the case of obtaining a septenary output value in this D/A converter for converting prescribed digital data into a PWM wave as an analog value, the input digital data are converted into four waveforms A to D by a PWM decoder 2 within 4 clocks based upon the count data of a 2-bit counter 3, the timing of the four waveforms A to D is adjusted by a D-FF 4 and the timing-adjusted waveforms A to D are synthesized by an adder 5 to obtain a PWM wave symmetrical about the center of signal energy in a time base direction and symmetrical about a reference level between positive and negative output values.

Title: Manufacture of semiconductor device
Inventor: USADA KAZUO
IPC: H01L23/495
Filed: 1982-12-27
Abstract: PURPOSE:To manufacture a plastic package by using a lead frame of one kind without changing the size of a stage in response to the size of a semiconductor chip by pasting a heat-resisting insulating tape on the surface of the stage to which the chip is fitted when the chip smaller than the size of the stage is loaded. CONSTITUTION:A gold pellet is placed on the stage 8, and heated and melted, the semiconductor chip 7 is compression-bonded with the stage 8 from the upper section of the pellet and die-bonded, and the insulating tape 11 is pasted on the stage 8 so that the outer circumference of the tape 11 is projected slightly to the outside from the stage 8 around the chip 7. Wires 9 are bonded, and the chip is molded. Even when the wires 9 hang down, the wires 9 are not directly in contact with the stage 8 owing to the insulating tape 11, and a short circuit is prevented. Since the insulating tape 11 is slightly larger than the stage 8, the end section of the stage 8 and the wires 9 are not in contact, thus completely preventing the short circuit.

Title: Pattern registration system for printed wiring board
Inventor: NAGAI TSUTOMU
IPC: H05K3/46
Filed: 1999-08-16
Abstract: PROBLEM TO BE SOLVED: To reduce the relative misregistration between patterns by providing a low-layer pattern recognition mark on the pattern which is one layer below a layer on which a pattern is to be formed and reading the mark with a camera for position detection through the insulating resin of the layer on which the pattern is to be formed, and then, registering the mark with an exposure recognition mark. SOLUTION: In the formation of a build layer pattern, a lower-layer pattern recognition mark 7 is formed simultaneously with the pattern in the lower-layer recognition mark and exposure recognition mark indicating area 5 of a mask film for exposing the surface-layer pattern of a core layer. Then the mark 7 is recognized with a camera for position detection incorporated in an exposing device through the resin of a build layer and registered with the exposure recognition mark 8 of a mask film for forming the pattern of the build layer. When the mark 7 is formed in the above-mentioned way, the sticking deviation between a base material and a film can be controlled with high accuracy, because the mark 7 can be registered directly with a pattern or hole to be registered instead of a visually deformed reference hole.
