Title: Gps receiving device
Inventor: YAMAOKA NOBORU
IPC: G01S19/27
Filed: 1985-02-28
Abstract: PURPOSE:To measure quickly the present position of a moving body, when a power source has been turned on, by providing a track data availability discriminating means, etc., and executing position measurement from stored track data, when the recollection has become unnecessary. CONSTITUTION:A radio wave from a GPS satellite is received by a reception processing part 12, and track data, etc. of each satellite are calculated and stored in a reception processing part use memory 14. On the other hand, time data of the track data is stored in a track data collecting time memory 16. When a power source is turned on again after the power source has been cut off, a collection time data T1 of the previous time and the present time data T2 are read out, and supplied to a track data availability discriminator 22. In this state, when a signal for making a recollection of the track data unnecessary has been received in the discriminator 22, the reception processing part 12 executes position measurement by the data which has been collected and stored before the power source is cut off. As a result, the collecting of the track data is unnecessary, and the position measurement can be executed quickly from the time when the power source is turned on.

Title: Reed-solomon code error detector
Inventor: OOTSUBO SHIYUUJI
IPC: G06F11/10
Filed: 1984-03-02
Abstract: PURPOSE:To attain quick error detection and correction processing by deciding whether or not a final syndrome is to be zero from the result of half-way operation of a syndrome in the reception with the transmission system using a Reed- Solomon code. CONSTITUTION:Each transmitted symbol is received sequentially by a reception circuit 1, a prescribed operation is inputted to syndrome operation circuits 11- 14 and the result is inputted to a correction execution circuit 60. Every time each symbol is received to the reception circuit 1, the syndrome is calculated by the operating circuits 11-14 by selecting a check symbol number N being a positive integer, a total transmission symbol number M and a value L satisfying L<N. When the symbols of M-L-set are transmitted to the reception side, the result of halfway operation of syndrome is discriminated. When the transmission has no error at all at the reception of the M-L-set of the symbols, a prescribed discriminating formula is established, and if the discriminating formula is not established, the error location detection and error correction are processed immediately.

Title: Inside-cylinder pressure detector for internal combustion engine
Inventor: IWATA TOSHIO
IPC: G01L23/10
Filed: 1988-02-22
Abstract: PURPOSE:To detect the timing at which the inside-cylinder pressure becomes the maximum with a simple constitution by inputting the output signal of an inside-cylinder pressure sensor in the form of an electric current and detecting a zero-crossing timing as the maximum point of the inside-cylinder pressure. CONSTITUTION:Electric charges Q are outputted from a piezo-electric type inside-cylinder pressure sensor 1 in corresponding to inside-cylinder pressures and an electric current of -dQ/dt is outputted from an operational amplifier 51 to a resistance 52 under the feedback control of the amplifier 51. When the voltage of the resistance 52 drops, the output current of the sensor 1 is converted into a voltage value. Since the maximum point of the waveform of the inside-cylinder pressure becomes the highest point, the zero-crossing point coincides with the maximum point of the inside-cylinder pressure and, when the zero-crossing point of the output signal of the amplifier 51 is detected, the timing at which the pressure becomes the maximum can be detected. Since high-frequency components of pressure vibration, etc., are superposed upon the output signal of the sensor 1 and it is necessary to remove the components before detecting the zero-crossing point, a low-pass filter 53 is provided between the amplifier 51 and a zero-cross detector 54. Thus clear signals indicating the timing at which the inside-cylinder pressure becomes the maximum can be obtained from the detector 54 with a simple constitution.

Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To prevent generation of a short circuit in a connection hole and a gate electrode and maintain high insulation pressure resistance even when misalignment is generated in forming an aperture portion in an interlayer insulating film, by forming an insulating film protected by a sidewall made of amorphous silicon onto the inner wall of the connection hole. SOLUTION: A connection hole for connecting a diffusion layer 17 formed in a semiconductor substrate 10 with an upper wiring layer 23 is formed. On the inner wall of the connection hole, a double-layer insulating film 20 including an SiN layer and an SiO2 layer protected by a sidewall 21A made of amorphous silicon is formed. Thus, even when misalignment is generated in forming an aperture portion in an interlayer insulating film 18, a shoulder portion of a gate electrode 15 or the like is prevented from being exposed and thus a short circuit is prevented from being generated in the connection hole and the gate electrode 15. Also, since the insulating film 20 formed on the inner wall of the connection hole is protected by the sidewall 21A made of amorphous silicon, damages to the insulating film 20 are prevented.
