Title: Data transmitting system
Inventor: TAKAHASHI YASUO
IPC: H04L5/06
Filed: 1979-07-13
Abstract: PURPOSE:To ensure an effective data transmissionalthough the length of 1-data frame differs among the transmitting stations, by switching the frequency of the local oscillator with every detection of the synchronous signal and then receiving selectively only the transmitting signal converted into the fixed frequency. CONSTITUTION:Frequencies f1-fn which are modulated by the data are allotted to data transmitting stations s1-sn. And frequency fr(r=1-n) is defined as fr= rf0-fs, and the transmitting signals are sent repetitively and continuously at time t formed by the synchronous signal of time t1 and the data signal of time t2. Receiving stations r1-rm receive transmitting signals f1-fn, and these signals are converted at frequency converter 1 into frequencies kf0+ or -f1-kf0+ or -fn by oscillation signal kf0 supplied from local oscillator 2. And only the signal of the station of fs is made to pass through BPF4 of central frequency fs. The synchronous signal is detected by synchronous signal detector 6, and the data signal is read by data receiver 5. At the same time, frequency setter 3 is switched every time the synchronous signal is detected by detector 6. Thus only the transmitting signal of the prescribed frequency is received selectively.

Title: Steam iron
Inventor: FUNAKOSHI KOJI
IPC: D06F75/14
Filed: 1989-04-10
Abstract: PURPOSE:To obtain a steam iron with a sufficient vaporization capacity even if steam is increased by providing a film, a mixture of polyphenyl sulfide resin and silica fine particles, on the inside of a vaporization chamber. CONSTITUTION:A vaporization chamber 1 wherein steam is generated, is provided on the top of a base 3 with a built-in sheathed-heater 2. A film 4, a mixture of polyphenyl sulfide and silica fine particles, is formed on the inside of the vaporization chamber 1, in order to improve vaporization efficiency. The film, the mixture of polyphenyl sulfide and silica fine particles, is applied and baked on the inside of the vaporization chamber. The silica fine particles are thus disclosed on the surface of the film and increase the surface area coming into contact with water. Furthermore, since the silica has a very highly hydrophilic property, it can instantaneously vaporize even a lot of water. The title iron is therefore made so that waterdrops are not spouted from a steam hole even if the steam is increased.

Abstract: PURPOSE:To obtain an air flow rate required for cooling a thyristor at a main part and an air flow rate required for transferring dust through a pipe at a central cleaner as well even at a low air flow rate by interlocking an input controlling slide volume on a hose grip and an air leaking unit. CONSTITUTION:A slide switch 2 is attached free to slide on a hose-end pipe 1 of a vacuum cleaner, and notch indicating plate 3 of suction force is provided beside the slide switch 2, on which 'high', 'medium', 'low' and 'off' are indicated.

IPC: H04M1/00
Filed: 1986-04-18
Abstract: PURPOSE:To surely inform an incoming call by detecting a noise level around a telephone set, comparing the detection output with a standard voltage, controlling the sound volume of a call tone to a sound volume coping with the noise and sending the result thereby giving a call tone of the pleasant sound volume even at a large noise or at a quiet surrounding. CONSTITUTION:A noise detection section 1 detects the surrounding noise, the detected output is rectified by a rectifier section 2 and a voltage representing the noise level is obtained. The voltage is compared with the standard voltage at the inside by a control section 3 and a control output proportional to the noise is obtained and the attenuation of an electronic variable resistor circuit 4 is decided. A call signal from a trunk line is detected by a 16Hz detection circuit 6 and a call tone generating circuit 7 generates a call tone depending on the detection output. The call tone has a value corresponding to the surrounding noise via the electronic variable resistance circuit 4 having a predetermined attenuation and is outputted from a speaker 5. Since the call tone is outputted by a sound volume in response to the surrounding noise and the incoming call is surely informed by a pleasant call tone in matching with the surrounding state.
