Title: Pulse width modulation control unit
Inventor: YAMAZAKI SHUICHI
IPC: H02P25/04
Filed: 1986-08-25
Abstract: PURPOSE:To heighten PWM (pulse width modulation) frequency and to strengthen resolving power, by providing clock pulses of different phases, multiple counters and logical circuits respectively. CONSTITUTION:To a programme interval timer (PIT) 11 8-bit data AD 0-AD 7 and counter select signals A 8 and A 9 are inputted from a microcomputer 4. On the other, to a PIT two clock pulses a and e of different phases are inputted from an oscillator 13. The PIT 11 outputs pulses with pulse width responding to the count value set by the use of the first and second counters built in. Through logical circuits 15 and 16 the pulses thus outputted are inputted into transistors Q1-Q4 of a motor driver 2 for PWM control over a motor 1.

Title: Effective utilization of memory in system for recording and reproduction
Inventor: INOUE KAZUO
IPC: G10L19/00
Filed: 1987-08-06
Abstract: PURPOSE: To effectively utilize a memory by checking the content of a recorded phrase, erasing soundless data when it is only made of silence and using it as a new phrase. CONSTITUTION: Whether or not a phrase just after sound recording processing is a silent phrase is checked/judged by whether or not the sound data in a memory area is amplitude data below a threshold every time sound recording processing is performed. Consequently, when the phrase is judged to be a soundless phrase, data in the phrase is cleared out or the soundless phrase is utilized as a new phrase without counting up a memory for storing the leading phrase number of unused area.

Title: Mask for solder paste printing and solder paste printing apparatus
Inventor: MOTOHASHI TAKAYUKI
IPC: H05K3/34
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To obtain a mask by which an unclear thing on a pattern such as whether the interval between patterns is ensured to be a prescribed value can be checked easily and surely by a method wherein a pattern for a gage is formed and arranged in a position in which a solder paste is printed on a board other than a practical pattern formation region.
