Title: Rare earth element-doped quartz glass and its production
Inventor: KAMIYA KAZUO
IPC: C03C14/00
Filed: 1990-01-23
Abstract: PURPOSE:To improve the intensity of emission spectrum and laser characteristics by dispersing phosphate of rare earth elements in quartz glass. CONSTITUTION:A porous glass base material having 0.3-1.0g/cm<3> average volume density is obtained by depositing fine particles of glass which are obtained from hydrolysis of Si compd. such as SiCl4 in flame. Then this base material is immersed in an org. solvent (e.g. methanol) solution containing a soluble salt of rare earth element (e.g. ErCl3) and if required, photosensitizer. Then the base material is dried in air, heated at 100-300 deg.C in an ammonia gas atmosphere so that ammonia gas is absorbed to neutralize the salt into hydroxide, and immersed in a solution containing phosphoric acid to change the rare earth elements into phosphate. Further the mother material is sintered at 1200-1800 deg.C in a He gas atmosphere to form transparent glass.

IPC: B60W10/18
Filed: 1991-02-04
Abstract: PURPOSE:To detect a preceding car without fail even in case of a curved running way, and to improve reliability of an automatic tracking system and the like. CONSTITUTION:Detection signal from a scanning laser radar device 10 is fed to an ECU 12. The ECU 12 detects a preceding car which runs on the same running lane, based on the detection signal from each sensor and the laser radar device 10. However, in the case that the preceding car can not be detected and also steering thereof is out of control, the ECU 12 judges that the preceding car is running on a curved way and the vehicle on which the ECU 12 is loaded, is running just before the curved way. Subsequently, an image obtained by a detection camera 24 of running way is processed by a computer 26 to calculate radius of the curved way, and, by changing a laser beam direction, the preceding car is re-detected.

Abstract: PURPOSE:To enable a proper control by a method wherein a detection area of an obstacle is divided into small areas and the obstacle is detected at each small area to judge a comprehensive degree of danger according to the ranks of the small areas and the degree of danger of the obstacle. CONSTITUTION:A controller detects a steering angle and a vehicle speed with a steering angle sensor 5 and a vehicle speed sensor 6 to estimate a slippage angle of a body and a turning radius and also a road of the vehicle. Then, the controller sets a detection area within a scanning range of a light emitting device 2 while dividing the area into a collision area, a near miss area and an alerting area by ranking. The small areas are determined by an angle of expansion from the center axis in the ongoing direction of the vehicle.

Filed: 1980-02-08
Abstract: PURPOSE:To perform a homing of a sailing object with a simple constitution, by discriminating whether an underwater sailing object is approaching from the back side or the front side of a target from the priodical reflected waves given from the target and accordingly inducting the direction during the start and completion of reception of the reflected waves. CONSTITUTION:The transmission wave of frequency fT transmitted via the transmitter TM plus the transmitter/receiver A and B is reflected at the target and then received at the receiver RV via the transmitter/receiver A and B. The reception frequency fR is expressed by an equation, where the underwater sound velocity is C, the speed of underwater sailing object is VG and the speed component on the axis of the target underwater sailing object is VT each. The VT is negative and positive when the sailing object tracks at the back side and the front side of the target respectively. Thus a comparison is given between the reception frequency fR and the reference frequency fRO=(C+VG)/(C-VG) to decide a back tracking or a front tracking. According to this discrimination, the direction of induction is decided.

Title: Arrangement for fan
Inventor: SUGAWARA NORIO
IPC: F04D17/04
Filed: 1981-02-02
Abstract: PURPOSE:To enable to deflect air flow for a large angle without changing the air-flow rate of a cross-flow fan, by making currents of air produced by vortices flow along the downstream portion of a rear guide, and thereby deflecting the flow of air ejected from the fan. CONSTITUTION:A cross-flow fan 7 produces current of air. In case that the angle theta of a rear guide 9b is smaller than about 60 deg., flow produced by vortices V is divided by a flow controlling member 11, and currents of air Fa between the flow controlling member 11 and a stabilizer 8 tend to issue in a horizontal direction by the function of the vortices V. However, since the amount of air of the currents Fa is much greater than that of currents Fb between the flow controlling member 11 and rear guide 9b, the direction alpha of air flow is made horizontal as a whole, i.e., substantially parallel to the direction of currents Fa, so that air flow can be deflected for a great angle without causing change in the air- flow rate.
