Title: Controller for meandering of metallic strip
Inventor: MIWA YOSHIKAZU
IPC: B21C47/34
Filed: 1995-01-25
Abstract: PURPOSE: To provide a controller which is capable of correcting the meandering of a metallic strip even in a state where tension is not imparted. CONSTITUTION: The meandering controller 20 is constituted of a detecting means 29 for detecting the meandering quantity of a transported metallic strip, control means 37, bridle roll 30, snubber roll 32 and tilting means 36 provided in the snubber roll. In a state where no tension is imparted to the metallic strip 28, the detecting means 29 detects the meandering quantity of the strip 28 and, in response to that output, the control means 37 calculates the tilting quantity, which is the quantity to be controlled, and outputs it to the tilting means 36. In response to that output, the tilting means 36 tilts the axial line of the snubber roll 32, in a horizontal plane including that axial line, against a perpendicular plane including the axial line of the bridle roll 30. Thus, a meandering correcting force is imparted to the metallic strip 28.

Title: Electronic scanning antenna
Inventor: SHIRAMATSU KUNIAKI
IPC: H01Q3/38
Filed: 1983-01-25
Abstract: PURPOSE:To reduce the side lobe produced by a quantized phase error at beam scanning by adjusting the phase of an input signal of a phase shifter as specified with a phase adjuster and setting the phase shift amount of the phase shifter to a prescribed value. CONSTITUTION:The phase of an input signal of the phase shifter 2i relating to the i-th element antenna 1i is adjusted by using a phase adjuster 9i based on the phase of an output terminal of a transmitter 7, for example, as -alphar<2m>, where alpha is an optional constant and i=1, 2-, (m) is a natural number. In setting the phase shift amount of said phase shifter 2i as [alphar<2m>-betai]B by a control signal from a control circuit 5, the phase of the signal applied to the element antenna 1i is [alphar<2m>-betai]B-alphar<2m>, where [X]B is a digital phase amount quantized by B closest to the X, beta is a constant corresponding to a beam scanning angle and beta is the minimum unit phase angle. Thus, the side lobe produced by the quantized phase error at beam scanning is reduced.

Abstract: PURPOSE:To reduce a device in size and to enable the light from a light-emitting section to efficiently land on a text by a method wherein a photodetecting element is built on a substrate, a light-transmitting layer is provided on or under the photodetecting element, and a light-emitting section built of an EL light-emitting body or the like is unified with the photodetecting element through the intermediary of the light-transmitting layer. CONSTITUTION:An EL element 2 is built on a glass substrate 1. Next, water glass is applied to the EL element 2 and then curing is accomplished for the formation of a first light- transmitting layer 3. Cr or the like is evaporated on the light-transmitting layer 3 for the formation of an electrode 4 to serve also as a light-screening film, wherein a light-receiving window 7 is provided by etching. Amorphous silicon is formed thereon by CVD, which is followed by the attachment of transparent electrode ITO. In this process, amorphous silicon is removed by dry etching from between the light-receiving window 7 and a photodetecting element 8. On the photodetecting element 8 thus constructed, a second light-transmitting layer 5 is formed. Light 10 from the EL element 2 travels through the light-transmitting layer 3, to light-receiving window 7, and the light-transmitting layer 5, and then lands on the section to be read of a text 6. The light reflected from the text 6 arrives at the photodetecting element 8, where it is converted into electrical signals.

Title: Reflection type ultrasonic wave switch
Inventor: OKAMOTO MINEO
IPC: G01S15/04
Filed: 1979-01-31
Abstract: PURPOSE:To prevent malfunction due to reflected wave from the floor surface by a method wherein an object to be detected is removed from the space between the ceiling and floor for a given period of time after power is turned on so that the traveling time of wave in the space is memorized, and at the same time detection area is defined. CONSTITUTION:When power switch for ultrasonic wave switch 14 is turned on, timer circuit 5 is actuated for a specified time, output form receiver 3 is input to the memory 7 via judging circuit 6. When ultrasonic wave go-and-return time t exceeds the time t1 set previously, the circuit 6 stores it as the go-and-return time of reflected wave. At normal operation, the time t stored in the memory 7 is read, gate control circuit 9 forms gate control pulse, which closes and opens the gate circuit 10. This allows the detector 11 to receive reflected wave that comes during a definite period t3, i.e. signal by reflected wave from the object to be detected present in the detection area. This eliminates detection output due to reflected wave from the floor, so that the switching circuit 12 works only when the object 3 is present in the detection area.

Abstract: PURPOSE: To obtain the novel optical path switching element which switches the optical paths of the 4-terminal light circulator by interposing optically anisotropic crystal between a pair of double-refractive prisms and letting two orthogoal polarizing components be selectively transmitted.  
     CONSTITUTION: When random-polarized light in entered from terminals IN-2, IN-4, light 40 is made to light 42 of P polarization of 45° in a double-refractive prism 32 and enters magneto-optic crystal 33, by which it is rotated 45° and light 43 is produced. The light 43 aligns to the S polarization plane in a double-refractive prism 31 and therefore the P polarization component of the light 43 is fetched as light 45 of output in terminal IN-3. Similarly, the light 41 entered from terminal IN-4 becomes S-polarized light with light 42 and when it further rotates 45° and enters the prism 31, it is in alignment to the P polarization plane and therefore it is fetched out as light 44 in terminal IN-1. In this way, the optical paths may be changed to 2-3, 3-4, 4-1, 1-2 between the terminals.
