Abstract: PURPOSE:To make a sound signal easily audible even in noisy circumstances by largely amplifying the sound signal inputted from an input means according to the magnitude of noises by means of an amplifier, and making the outputted signal large. CONSTITUTION:A vehicle speed signal is always detected by a sensor 10, inputted through a waveform shaping circuit 9 to a control circuit 8, the control circuit 8 where the vehicle speed signal is inputted computes the magnitude of the external noise based on the vehicle speed, and increases the amplification degrees of amplifiers 3a and 4a according to the magnitude. Consequently the sound signal inputted from a microphone 7 is largely amplified according to the magnitude of the noise, and transmitted from a radio 2 to the other side as the large sound signal. On the other hand, the sound signal inputted from the other side by the radio 2 is largely amplified according to the magnitude of the noise, and outputted through a speaker 6 as the large sound signal. Thus, even when the external noise is large, the sound signal can be made easily audible on both transmission and reception sides.

Title: Ion current detector
Inventor: IKEUCHI MASAYUKI
IPC: F02P17/12
Filed: 1990-11-09
Abstract: PURPOSE:To improve detectability by applying positive-polarity bias voltage to a pair of spark plugs, respectively. CONSTITUTION:At a spark timing for an internal combustion engine, ignition high voltage arises in the secondary winding 1b of an ignition coil 1, a discharge current flows in a passage shown in an arrow mark, and discharge occurs between the respective electrodes of spark plug 3a, 3b to ignite and fire mixture in a cylinder in a compression stroke. At this time, the combustion of mixture involves electrolytic dissociation to create ions. With the movement of electrons due to positive-polarity bias from a power source 8, an ion current flows in a cylinder where combustion occurs, but electrons have greatly smaller mass and faster moving speed than positive ions so that a great amount of ion current is obtained. Voltage developed in an output terminal 10 by the ion current can be detected to identify the combustion of mixture. It is thus possible to improve detectability.

Abstract: PURPOSE:To prevent the step disconnection of the second layer wiring formed on the first layer wiring through the intermediary of an insulating film from occurring by a method wherein the stepped first wiring is formed in the section by the initial wet-etching process and the successive dry-etching process. CONSTITUTION:A photoresist layer is exposed using a photoresist to form a photoresist 6c after specific pattern on the exposed part on the surface of the first aluminum wiring layer 3. The first aluminum layer 3 is wet-etched leaving it in the specified thickness using the photoresist as a mask and then the residual part is dry-etched away to form the first aluminum wiring 3. Next, after coat-forming an interlayer insulating film 4 on the whole surface including the first aluminum wiring 3a, aluminum is evaporated on the whole surface and then the aluminum layer is etched away after specific pattern to form the second aluminum wiring 5. The second aluminum wiring 5 is stepped in the section similar to the first aluminum wiring 3a. Through these procedures, the second wiring 5 can be formed interdigitally with the first aluminum wiring 3a thereby preventing any step disconnection from occurring.

Filed: 1993-12-06
Abstract: PURPOSE:To utilize a resource by providing toner-saving mode in which development conditions and transfer conditions are altered, thereby eliminating a troublesome operation and suppressing toner consumption. CONSTITUTION:The device employs a toner reuse type by which, for example, untransffered toner and transfer residual-toner are accumulated on a cleaning roller 37 during the insertion of paper, and the untransferred toner and transfer residual-toner are returned to a developing roller 36 during the non-insertion of the paper. Here, to print in the saving mode, images, in particular characters and lines, are formed as so-called center omission images, whose outlines are clearly seen but toner is not attached to their middle parts, and the untransferred toner in the middle parts is recovered to be reused for development. In this case, a switch S1 is turned off, and the pressure of a transfer roller 32 is increased. When the pressure of the transfer roller 32 is increased, the toner aggregates on the surface of a photoreceptor 31 and firmly sticks to the photoreceptor 31, and its force becomes stronger than the action of an electric field with which the toner is transferred to the transfer material P, so that complete transfer is not carried out.

Abstract: PROBLEM TO BE SOLVED: To automatically adjust the center frequency of a signal to be measured at the time of measuring the harmonic component of the signal by impressing a voltage signal which makes the center frequency of the signal equal to the phase of a reference signal upon a Gaussian filter 4. SOLUTION: A Gaussian filter 4 generates a center frequency based on a reference signal inputted from an oscillator 2 through a buffer 3 and, when a signal to be measured is inputted from an input terminal 1 through a switch 5a, the filter, 4 mixes the center frequency with the harmonic component of the signal to be measured and outputs the mixed signal to a comparator 6. The comparator 6 compares the mixed signal with a reference signal inputted through a buffer 3b , fetches the shifting amount of the phase as a voltage value, and inputs the voltage value to a CPU 11 through an amplifier 9 and an A/D converter 10. The CPU 11 outputs a voltage signal which makes the phase of the center frequency generated by the filter 4 equal to that of the reference signal to the filter 4.  Therefore, the phase of the center frequency can be adjusted automatically even when a different signal to be measured is inputted.
