Title: Active noise eliminating device
Inventor: TACHIBANA TOSHIYUKI
IPC: H03H17/00
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To make auditorily inconspicuous an identifying sound which is used to identify a secondary sound path (transfer function). SOLUTION: To identify the secondary sound path C, a dummy signal m(k) generated by a dummy signal generator 15 after having its level adjusted by a level adjustment part 18 is radiated as the identifying sound from a secondary sound source speaker 7 to the secondary sound path C. At this time, a level detection part 19 detects the output signal e (k) of an error microphone 11 when the identifying sound is not outputted and then noise level which is left in an exhaust duct 1 without being removed completely is detected. According to the detected level, the level adjustment part 18 is controlled to make the radiation level of the identifying sound high enough to identify the secondary sound path C, i.e., nearly equal to noise level, and consequently the identifying sound is prevented from being more conspicuous than the noise.

Filed: 1992-05-08
Abstract: PURPOSE:To exactly recognize a DCC even when a detecting hole for discrimi nating a cassette as the DCC is decided to be blocked up due to some cause or other. CONSTITUTION:It should not happen that plural detecting holes for discriminating tape length provided on a cassette half of the DCC are all blocked up. Consequently, when even one hole is open, decision can be made as the digital compact cassette. Therefore, when the detecting hole for discriminating the cassette is decided to be open by using a hole detecting signal outputted from an open/close hole sensor 19, the cassette is recognized as the DCC by a system controller 16, and when the detecting hole for discriminating the cassette is decided to be blocked, whether all the detecting holes for discriminating the tape length are blocked or not in very respect is checked. Then, when even one out of the detecting holes for discriminating the tape length is open, the cassette is recognized as the DCC, and when all of the holes are blocked, the cassette is recognized as an analog compact cassette (ACC), and hence a cassette identification signal CID is inputted to an analog audio circuit 20.

Abstract: PURPOSE:To form sufficient swirl at the time of combustion by forming a bulkhead parting a combustion chamber into the space, to which exhaust valves face, and the space, to which the exhaust valves do not face, and communicating path in a part of the bulkhead. CONSTITUTION:A screen bulkhead 12 parting a combustion chamber 4 into the space to which a exhaust valves 6 and 7 face and the space to which the exhaust valves 6 and 7 do not face without preventing the directing of fuel spray is formed in the combustion chamber 4 between the cavity 2 formed on the top face of a piston 1 and cylinder head 2. A communicating path 13 communicating the space parted by the bulkhead 12 is formed in a part of the bulkhead 12. Since owing to this constitution, ignition and combustion are started firstly from the space, to which the exhaust valves 6 and 7, which is always exposed to the exhausted air of high temperature and heated, face, the pressure difference is generated between both spaces parted by the bulkhead 12 in the beginning of combustion. Therefore, jetted air flows out through the communication path 13 resulting in the formation of swirl.

Title: Cordless telephone set
Inventor: WAKAYAMA SHINICHI
IPC: H04W76/02
Filed: 1988-05-14
Abstract: PURPOSE:To attain power supply stop to a speech circuit section and speech end with simple structure and simple circuit constitution by adopting the constitution such that a speech circuit section of a slave set is brought into the end of call via a master set if the slave set in busy state is returned to the home position in the master set and the power supply to the speech circuit section is stopped. CONSTITUTION:If a slave set 1 is contained in a containing section 30 of a master set 3 while a speech switch 16 is being depressed representing the speech state, since a light emission element 20 displays the talking state, a photodetector 35 detects its display state. Thus, in the presence of an output from the photodetector 35, an end of call control output circuit 51 sends an end of call control signal to the slave set 1 via an antenna 31. The slave set 1 receives the end of call control signal via the antenna 11 and uses an end of call control circuit 43 to stop the power supply from a battery 44 to the speech circuit section 42. Thus, the state reaches substantially the end of call, the power consumption in the succeeding speech circuit section 42 is prevented and the light emission element 20 goes off.
