Title: Ignition timing sensing method for internal combustion engine and its device
Inventor: KIKUCHI TOMOSHI
IPC: F02D41/40
Filed: 1999-08-16
Abstract: PROBLEM TO BE SOLVED: To provide an ignition timing sensing method and device for an internal combustion engine which can estimate an ignition timing independently of an operation condition of the internal combustion engine. SOLUTION: An internal combustion engine has a pressure sensor for sensing inside pressure of a cylinder. In such an internal combustion engine, fluctuation of the inside pressure of the specified cylinder is sensed from a compression stroke to an explosion stroke, wavelet-conversion is carried out in respect to a signal indicating fluctuation of the pressure inside the cylinder, a characteristic peak is sensed from a spectrum of the signal which is wavelet-converted, and the sensed peak is determined as an ignition timing. In such a case, in order to suppress calculation work of the wavelet-conversion, the signal of the inside pressure of the cylinder is first divided into plural frequency bands which are continuously distributed from low to high bands. Wavelet-conversion is performed and an ignition timing is obtained in each frequency band.  The ignition timing in the low frequency band is corrected by the ignition timing in the high frequency band, for improving accuracy of the ignition timing.

Inventor: KIMURA ETSUKO
IPC: H01L27/12
Filed: 1988-09-16
Abstract: PURPOSE:To allow the selective hydrogenation of a polycrystalline silicon film without deteriorating the properties of the lower transparent electrode of a charge holding capacitor parts by selectively depositing and forming an insulating film contg. active hydrogen in the film to the part exclusive of a charge holding capacitor and thermally diffusing the hydrogen in the film, thereby hydrogenating the film.

Title: Handset speech device
Inventor: MATSUDA MITSUHIRO
IPC: H04M1/00
Filed: 1988-09-16
Abstract: PURPOSE:To adjust a call sound volume and to keep a speech sound volume constant by driving a series circuit consisting of a speaker and the resistor of a sound volume adjusting circuit with a current source output format at the time of performing speech, and driving it with a voltage source output format at the time of calling. CONSTITUTION:A call tone signal drives the series circuit consisting of the variable resistor VR for adjusting sound volume of a handset 1 and the speaker SP via a call tone amplifier AMP3 and a switch circuit SW. When the handset 1 is lifted, the switch circuit SW is turned off, and a reception signal is inputted to a reception amplifier AMP2 via a hybrid circuit 28, and a V-I converter CNV drives the sereis circuit consisting of the variable resistor VR and the speaker SP by a current proportional to the output voltage of the reception amplifier AMP2. In such a case, since the output impedance of the V-I converter CNV shows infinity  essentially, a current is not affected by the resistance value of the variable resistor VR. In such a way, it is possible to perform the adjustment of the sound volume effectively by the variable resistor at the time of performing the call and to perform the speech at a constant sound volume.

Filed: 1991-09-10
Abstract: PURPOSE:To provide the display panel device having an exposing part larger than heretofore and functions as a display part having good visibility without increasing the number of light emitting elements by constituting a light guide of transparent lens member and diffusing member CONSTITUTION:The light guide 11 is constituted of the diffusing member 11A and the transparent lens member 11B. Further, the two members 11A, 11B are fixed by a transparent adhesive. The diffusing member 11A is formed of, for example, a polystyrene resin or acrylic resin contg. diffusing particles and the one transparent lens member 11B is formed of a transparent acrylic resin. The luminous flux 10A from a light emitting diode 10 is projected by having the directivity of a certain range and is made incident in a substantially wasteless form on the diffusing member 11A. The incident light on the diffusing member 11A is diffused by its diffusivity but the diffusing member 11A is formed in the position of the display part 9 and, therefore, the most of the diffused light is visible. The visibility from vertical and lateral directions is thus improved.

Title: Check circuit for smoke sensor
Inventor: MORISUE KAZUNARI
IPC: G08B17/107
Filed: 1988-09-14
Abstract: PURPOSE:To discriminate whether data are due to the deterioration of a light emitting or light receiving element or contamination of a wall surface by comparing the value of analog data returned from a smoke sensor at the time of checking the operation and no-operation of the sensor with the value corresponding to the smoke concentration when a fire starts. CONSTITUTION:When work check controlling data are transmitted, a multiplex transmission circuit 8 discriminates the data, instructs the checking of the actuation of a signal process circuit 9, and turns on and turns off a transistor Q3. A repeater discriminates the value of returned analog data and, when the value is lower than the actuating level, discriminates that the value is caused by a defective element. When no-operation check controlling data are transmitted, a no-operation checking command is given to the signal process circuit 9 and a transistor Q4 is turned on. In addition, another transistor Q2 is turned on an turned off. When the value of returned analog data exceeds the actuating level, the repeater discriminates that the value is caused by contamination.

Title: Reader for tri-state digital encoder
Inventor: MIYAZAWA MASAHITO
IPC: G02B7/10
Filed: 1988-09-14
Abstract: PURPOSE:To read an encoded value directly with simple circuit constitution by providing an encoder means and a detecting means which detects the encoded value according to the output of the encoder means at respective logic levels. CONSTITUTION:Data supplied to input terminals (a) and (b) of the tri-state digital encoder K have invariably opposite logical levels through the operation of an inverter A. Output terminals 1 - (n) of the encoder K, on the other hand, are pulled up, so they enter an 'H' state in an 'open state' regardless of the input data. In other states, the logic levels of the input terminals of the connected encoder K are outputted as they are and supplied to and stored in an interface circuit IF. Consequently, the output-side level of the encoder K which is stored can be read and processed by a central arithmetic unit CPU when necessary. Consequently, the output of the encoder K is readable without requiring any special circuit element.
