Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To effectively avoid contact matching the intention or sense of a driver by starting the operation of an automatic brake device at the time point when the avoidance by steering operation is disabled. SOLUTION: A sensor output signal is inputted, a state amount is calculated (S10), and contact avoidance enabled relative distances (threshold values) Ls and Lb by steering operation and automatic brake are calculated (S12). Next, it is judged whether the measured relative distance is larger than the contact avoidance enabled relative distance Ls based on the steering operation or not (S14). In the case of YES, automatic brake-off is performed, namely, the brake mechanism is not automatically operated (S16). In the case of NO (S14), on the other hand, it is judged the contact avoidance by the steering operation is disabled, and it is judged whether the relative distance exceeds the contact avoidance enabled relative distance Lb by the automatic brake or not (S18).  In the case of YES, it is judged the contact avoidance by the automatic brake is enabled, and automatic brake-on is performed.

Filed: 1990-01-29
Abstract: PURPOSE:To measure the thermal mutual action of a multiple-beam semiconductor laser readily by adding a step for conducting a current less than a threshold value through a selected laser element. CONSTITUTION:An element (r) is selected among a plurality of laser elements, and a current Ir is conducted through the element. A light output Pr is measured with a detecting part 7. At this time, the temperature of a multiple-beam semiconductor laser 1 is made to be T deg.C. Then the temperature of the semiconductor laser 1 is increased by DELTAT deg.C with a Peltier element 5. The current Ir is conducted through the element (r), and a light output Pr' is measured with a photodetector 2. A temperature coefficient Kr of the element (r) is obtained with K=(Pr-Pr')/DELTAT based on the obtained measured value. Then, an element (s) which is different from the element (r) is selected. The temperature of the semiconductor laser 1 is made to be T deg.C. A current Tr is conducted through the element (r) and a current Is' which is less than its threshold value is conducted through the element (s) at the same time. Thus, an operating voltage Vs' of the element (s) and a light output Psr are measured. Mutual action Crs which is given to the element (r) from the element (s) can be obtained with Crs=(Pr-Psr)/ KrWs (where Ws=Is'Vs') based on the above described measured values.

Filed: 1982-02-10
Abstract: PURPOSE:To detect efficiently interference disturbance of identical frequency, by transmitting an encoded voice signal from a transmission side together with an periodically added frame signal, etc., and detecting the reception level of the signal all the time and evaluating the reliability of said added signal on a reception side. CONSTITUTION:On the transmission side, a signal sequence generated by adding the frame signal between encoded voice signals at specific intervals is transmitted. On the reception side, an interference deciding device 14 detects frame signals from a frame signal extracting device 11 for a specific time to measure the detection rate of the frame signals and a reception level detector 9 monitors the detection result of the reception level all the time. Once discriminating that the measured value of the reception level is high and the detection rate of the frame signals decreases, the interference deciding device 14 decides that there is interference disturbance of identical frequency. Further, the signal sequence may be constituted by adding discrimination signals, pseudo random signals, or error correction codes instead of the frame signals.

Title: Automatic tuning receiver
Inventor: MOTOHASHI MINORU
IPC: H03J1/00
Filed: 1982-02-10
Abstract: PURPOSE:To correct the time lag of a tuning voltage due to a low-pass filter by substituting a tuning clock with the output voltage of the low-pass filter when a stop pulse is sent. CONSTITUTION:When the stop pulse is inputted, a controller stops the tuning clock to be sent to a pulse synthesizer to open a gate which allows an A-D converter output to pass through it momentarily, and inputs the A-D converter output based upon an actual tuning voltage to an up/down counter, whose count contents are replaced. Consequently, tuning data at the point of stop pulse generation is obtained and correct tuning is performed without reference to the time lag due to the low-pass filter.

Title: Emulator control method
Inventor: YANAGAWA TSUTOMU
IPC: G06F9/44
Filed: 1986-01-30
Abstract: PURPOSE:To shorten the code transfer time and at the same time to improve the response for the control of an emulator by outputting an instruction code compressed into an intermediate code through the host computer side and then interpreting the code into a practicable form through the emulator side. CONSTITUTION:A series of intermediate codes undergone the data compression are outputted from a host computer 1 and sent to the side of an emulator 2 via a cable 3. A receiving circuit 21 receives those intermediate codes and sends them to the emulator 2. The emulator 2 interprets the received codes and converts them into the practicable commands that can control directly a target 4 to execute them. In this case, the intermediate codes are obtained by compressing the redundant data on the string of an ASCII type by means of a special code like an ESC sequence, etc. While the intermediate code undergone the data compression is converted into a code approximate to such a type that can be directly interpreted by the emulator 2. Thus it is possible to shorten greatly the code transfer time and also to improve the response for control of the emulator.

Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device capable of properly preheating a filament at the time of preheating and to decrease losses by reducing a preheat amount of the filament at the time of lighting. SOLUTION: An inverter circuit 14 oscillates with a high frequency at the time of preheating, and a resonance frequency of a filament preheat transformer Tr1 and of a capacitor C3 is set higher than a frequency at the time of preheating.
