Title: Light pulse radar apparatus for vehicles
Inventor: ENDOU HIROSHI
IPC: G01S17/931
Filed: 1981-10-31
Abstract: PURPOSE:To improve receiving sensitivity by an apparatus wherein a laser beam is divided into a carrier beam and a local oscillation beam, and a beat signal is obtained from the local oscillation beam and the reflected beam from the object to the carrying beam having been subject to pulse modulation and frequency conversion. CONSTITUTION:The output beam from a laser 11 is divided into a carrier beam Lc and a local oscillation beam Ll by a beam distributor 12. The carrying beam Lc is applied to an acoustic beam reflector 13 to be modulated with a high frequency signal from a high frequency generator 14. An output diffraction beam Ld from the deflector 13 is applied to a beam modulator 17 via a slit 15 and a lens 16 to be pulse-modulated and then sent out in the running direction of a vehicle from a transmission optical system 19. A reflected beam from the object is received by a receiving optical system 20 and fed to a receiving element 22 after being superimposed with the local oscillation beam Ll in a beam mixer 21. A beat signal eB obtained by the element 22 is fed through an intermediate frequency amplifier 23 to a detector 24 where it undergoes envelop detection. A video signal ed thus obtained is fed to an information processing circuit 25 together with a trigger signal et in synchronism with a modulation signal em of a pulse modulator 18. The circuit 25 receives ground speed information from a speed sensor 26 and issues an alarm (a) if a possibility of collision be detected.

Title: Composite sintered body for silicon carbide base
Inventor: OGATA KOJI
IPC: C04B35/591
Filed: 1990-06-29
Abstract: PURPOSE:To improve an anti-spalling property of a silicon nitride sintered body by nitriding the mixture of specified ration of the metallic silicon powder and fibers of one or more kinds of B, Mg, Al, Si, etc. CONSTITUTION:Into the silicon metallic powder and 0.2-40 wt.% of one or more kinds of the fibers selected from B, Mg, Al, Si, Ti, Cr, Fe, Ni, Cu, Zn, Sn, Pb and an organic binder such as acryl resin are added and mixed by using ethanol, etc., as a solvent. This mixture is dried, pulverized and mixed, press molded and sintered the molds in the nitrogen atmosphere. When a small amount of hydrogen is mixed into nitrogen, the nitridation of metallic silicon is conveniently accelerated. The improvement on the anti-spalling property is not caused by the loading of the fiber less than the lower limit, and in the case of exceeding the upper limit, fibers which do not form a reactive layer with the matrix are increased and the lowering of the strength is enhanced.

IPC: A47K3/00
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To reduce the cost by decreasing the number of parts by unifying substrates or control panels, of which the main function is equal, by providing a means for discriminating the presence/absence of optional function of equipment, of which the main function is equal, and a means for judging whether or not the operation of that optional function is to be accepted. SOLUTION: The presence/absence of a filtering function as the optional function of an air bubble generator is judged by an optional function presence/ absence discriminating means 31. First of all, it is watched whether a three-way valve position signal is detected or not. In case of YES, the permission of filtering function (the presence of a filter) is judged. In case of NO, on the other hand, a three-way valve is driven and the position signal of the operated three-way valve is waited for prescribed time. When no signal is detected within the prescribed time, the inhibition of filtering function (the absence of the filter) is judged. This discriminated result is sent to an acceptance judging means 32, and the acceptance judging means 32 regulates a manipulating means 33 or an operating means 34.  Namely, based on the presence/absence or permission/ inhibition judgement of the optional function, the operating switch of the manipulating means 33 is to be accepted or not to be accepted.
