Title: Signal amplitude adjustment circuit
Inventor: YOSHIZAWA AKIHIRO
IPC: H04N5/08
Filed: 1989-12-25
Abstract: PURPOSE:To attain amplitude adjustment of an external input video signal suitable for a television receiver or the like with simple circuit constitution by connecting a video input line via a resistor automatically when a changeover switch is thrown to the position of an external input and inputting an input signal to a synchronizing separator circuit while the amplitude is reduced with a division ratio of an output impedance of an external device so as to avoid the use of a special circuit and an exclusive IC. CONSTITUTION:When a changeover switch 3 is thrown to the position of an external video signal input terminal 2, a high level voltage is outputted from an input discrimination circuit 11, a transistor(TR) Q110 is turned on and the amplitude of the external video signal is decided by the impedance division between an output impedance rEXT8 of an external device and a resistor R19. Thus, the amplitude of the external video signal is made equal to the amplitude of an internal video signal and inputted to a buffer circuit 4 and since a synchronizing signal separated by the synchronizing separator circuit 6 has the same amplitude independently of external and internal input signal, the same synchronizing signal is outputted.

Filed: 1993-12-28
Abstract: PURPOSE:To connect an external machine device such as an MIDI piano, etc., to a 'KARAOKE' (orchestration without lyrics) system and to operate it syn chronizing with the pronunciation of the 'KARAOKE' in an electronic circuit. CONSTITUTION:An MIDI filter 25 and a time offset filter 12 are connected to a sequencer 11. The MIDI filter 25 is the filter performing the operation such as that it rewrites the MIDI data to a format which the MIDI piano 27 reads them or the like.

The operation time difference of the MIDI piano 27 is about 500ms, and the same of the electronic circuit is nearly zero. Thus, the time offset filter 12 delays the inputted MIDI data by 500ms to output to respective parts. As the data delayed by the time offset filter 12, the performance data excepting a piano part, the lyrics display data and the effect control data, etc., outputted to a DSP are included.

IPC: F02M35/10
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To enhance the characteristic of distributing to cylinders the exhaust recirculated to an intake passage located upstream of an intake collector. SOLUTION: The branch passages 5a-5d of cylinders are connected to the side face of an intake collector 4 and an intake passage 6 is connected to one end.
