Title: Ultrasonic sensor
IPC: G01S15/87
Filed: 1992-03-26
Abstract: PURPOSE:To prevent the malfunction of an ultrasonic sensor caused by another intruding object by again comparing reflection patterns when a movement detecting signal is generated after detecting the existence of an object and, in case the existence of another object is detected, extending the termination of the detecting signal by a prescribed period of time. CONSTITUTION:When a detecting signal in a movement detecting system is generated after the existence of an intruding object, the reflection patterns from the object before and after the movement of the object is detected stored in storage circuits 17 and 18 are again compared 15. In case the reflection patterns do not coincide with each other similarly to the case where the existence of the intruding object is detected, a delay circuit 16 extends the termination of detecting output by a prescribed period of time. When a movement detecting signal is generated during the extended period of time, the detecting output is not terminated until the detecting signal in an existence detecting system obtained from the circuit 18 becomes coincident with the detecting signal stored in the circuit 17. Therefore, even when the movement of another intruding object is detected while an intruding object already exists, it does not occur that the already intruding object is misrecognized as a stationary object.

Thus, as the direction of the electric fields 1, 2 approaches without changing the quality of the electric fields 1, 2, the synthesized electric field 5 is decreased and the attenuation of components 1, 2 is decreased. In receiving the components 1, 2 by the polarization direction rotating device comprising circular waveguides W shown in figures c, d, e and twisted rotating fins 7-10, the electric charge distribution on the fins is obtained at the inlet as shown in the figure (c), and since the fins are rotated at the inlet as shown in the figure (c), and since the fins are rotated gradually and bonded at the outlet, the components are added and strengthened as shown in the figure (e). In giving a taper to the fins between the inlet and outlet, the major wave in the waveguide is led.

Title: Superconductive coil
Inventor: NAKAO HIROYUKI
IPC: B60L13/04
Filed: 1987-03-24
Abstract: PURPOSE:To rapidly and efficiently recover refrigerant gas after cooling by forming a gradient in a cooling tank. CONSTITUTION:Liquid helium is supplied by a supply pipe 30 to a linear section 48a at the lower side of a liquid helium containing space 48. It branches to right and left sides while cooling a superconductive coil member 54 to arrive at an upper section 48b. The liquid helium is evaporated as helium gas upon cooling of the member 54 at this time. The helium gas is recovered from a recovery tube 33 (recovery branch tube 31 and a recovery main tube 32). Since a gradient is formed at the upper section 48b of the space 48, the recovery can be sufficiently conducted even if the tube 31 is opened to the side of the space 48.

Title: Manufacture of combustion detecting element
Inventor: YAMANA TOSHIFUMI
IPC: F23N5/24
Filed: 1980-05-28
Abstract: PURPOSE:To provide electrodes adjacently to a slit, by a method wherein after a pair of electrodes have been formed on both sides of an element substrate, a slit is formed dividing said electrodes into two sets. CONSTITUTION:A pair of electrodes 3 and 3 of an electrode material such as platinum or the like are formed on both sides of an element substrate 1 made of an oxygen ion conductive solid electrolyte or metal oxide semiconductor so as to extend over both sides of a position where a slit 2 is to be formed. Then, the slit 2 is formed at said position. Consequently, said electrodes 3 and 3 are divided into two sets, one side and the other side, to obtain a detecting element. Thus obtained detecting element has each set of electrodes which are arranged adjacently to each other so as to abut on the slit respectively. Therefore, when the combustion state of a burner is measured, it is detected by the respective sets of electrodes under the same conditions with each other. Accordingly, malfunction will never occur, and there is no possibility of a short circuit between the electrodes because no electrode material hangs over the slit, unlike the method wherein after a slit has been formed electrodes are formed.
