Title: Drive circuit and television receiver using the same
Inventor: YOSHIDA TOMOISA
IPC: H04N5/63
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To detect a short-circuit of a load at low cost. SOLUTION: The voltage across the dropper resistor R1 of a load detection circuit 16 connected to an audio amplifier power supply line 24 is divided by using resistors R2, R3 and a transistor(TR)1 is on/off-controlled based on the voltage across the resistor R3. When the load is short-circuited, the TR1 becomes conductive and provides its output to the CPU 28 of a control circuit 18. The CPU 28 outputs a control signal accordingly to turn on a TR2, thereby deactivating a relay 32. Then, a power consumption circuit 14 is turned off and supply of power is cut off.

Title: Induction apparatus
Inventor: NAKAMAE JUNICHI
IPC: G01S13/88
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To prevent a plurality of flying objects from being induced to the same target. SOLUTION: Deflected transmission and reception waves are switched to a vertical or horizontal deflection wave according to a deflection wave switch signal 29. A mono-pulse comparator 4 receives reception signals 22a to 22d, and outputs a Σ signal 23, ΔAz signal 24, and ΔEl signal 25. When a level of the Σ 23 signal is a preset value or more, a search unit 6 outputs a search signal 26 indicating a target search. When a transmission trigger pulse 27 is outputted to the transmitter 2, a distance computer 7 measures a time until the search signal 26 is received, computes a distance up to the target, and outputs a distance signal 28. When a transmission source discriminator 8 receives the distance signal 28, it stores that value, and outputs a deflection wave switch signal 29.  After the deflection wave switch signal 29 is outputted, if a value of a distance signal 28 to be received again does not match the deflection wave switch signal 29, the received reflection wave is judged to be due to another induction apparatus, and continues a target search.

Title: Rotating speed detector
Inventor: TERAMAE KATSUHIRO
IPC: G01D5/245
Filed: 1993-12-10
Abstract: PURPOSE:To reduce detection errors caused by temperature change. CONSTITUTION:Resistors R1, R2 for detection are connected to a pair of magnetic detection coils 2a, 2b in series respectively, which are driven by high frequency current generated by an oscillator provided with an active element 9. Detection signals of each magnetic detection coil 2a, 2b are taken out from the connection points of the magnetic detection coils 2a, 2b and the resistors R1, R2. After the taken-out detection signals are rectified in rectification circuits 5a, 5b, differential amplification is performed in a differential amplifier 6. And the output of the differential amplifier 6 is compared with reference voltage generated in a reference voltage generation part 8 in a comparator 7. And, the output of the comparator 1 becomes detection output in accordance with the recess and projection of a rotor. In this constitution, since the two magnetic detection coils 2a, 2b are driven under approximately the same conditions, a difference of detection sensitivity between the two detection signals caused by temperature change is difficult to produce.

Title: Preparation of plastic lens having refractive index distributing
Inventor: KENMOCHI KATSUE
IPC: B29D11/00
Filed: 1987-12-08
Abstract: PURPOSE:To obtain the subject lens having an arbitrary refractive index distribution, by evaporating a mixture of a plurality of monomers having each different monomer b.p. and polymer refractive index and polymerizing them while condensing the vapors on a core material. CONSTITUTION:A mixture of monomers 2 consisting of a low b.p. monomer liq. A and a high b.p. monomer liq. B is put in a flask 1 and heated. When the temp. of the mixture 2 is elevated and exceeds the b.p., generated vapor is introduced into a reaction tube 6 and a layer adhered and condensed on a core material is solidified and fixed by UV light from a UV lamp 9 while the core material is rotated in the direction of an arrow. A solidified layer 12 is thereby gradually accumulated around the core material 8. As the vapor compsn. from the flask 1 gradually shifts to the higher b.p. side, with development of the layer 12, the ratio of a polymer of the high b.p. monomer becomes higher. Since it is possible by using this method to change largely the ratio of compsn. of two or more monomers, it is possible to make the refractive index distribution constant large, to make the numerical aperture of a lens large and to obtain an erect image of the same magnification with a short cylindrical body and as a relation between the diameter and the refractive index of the cylindrical body is easily controllable, a stable quality can be obtd.

Abstract: PURPOSE:To restrain stickness of bottom dross to a steel sheet by arranging a porous plate restraining the flow in a bath between a sink roll and the bottom part of a pot. CONSTITUTION:By arranging the porous plate 6 between the sink roll 2 and the bottom part of the pot in a zinc bath vessel, the flow in the bath generated by rotating the sink roll 2 and shifting the galvanized steel sheet 4 in the bath is shut off with the porous plate 6 to restrain the raise-up of the bottom dross 7. At the same time, as a part of the vigorous stream between the sink roll 2 and the porous plate 6 is flowed out from the holes 5 in the porous plate 6 and shifted to the lower part of the porous plate 6, the bottom dross 7 is not so much deposited at the lower part of the porous plate 6 that the raise-up of the bottom dross 7 generates.
