Title: Absolute position detector
Inventor: NAKAJIMA KEIICHIRO
IPC: G01B7/00
Filed: 1987-02-09
Abstract: PURPOSE:To reduce the size and cost of a battery by supplying the electric power from the battery at all times until a motor stops after being powered off and then supplying the power source from the battery intermittently at a constant period thereafter, and thus reducing the power consumption. CONSTITUTION:A control circuit consists of a power-off detecting circuit 11 and a power supply limiting circuit 12. Then when the power source is on, a CPU 1 detects an absolute value with position (angle) data S2 and data S5 on a rotating speed. While the power source is turned off, on the other hand, the battery B begins to power on a counter circuit 3, a rotation signal processing circuit 5, and a rotation detector 7 through a switching circuit 2. Then the circuits 3 and 5 are powered on at all times from the battery B even when the power source is turned off, but the power supply to the detector 7 is controlled by the circuit 12 according to a specific time sheet. Further, a pulse output from the circuit 5 is inspected every time the electric power is supplied to the detector 7 from the battery B and when there is the output, the circuit 3 measures it. An angle detector 6, on the other hand, uses a detector for the absolute position, so it can detect the angle of the motor M at all times without being powered on.

Title: Lens
Inventor: SAMU EICHI UON
IPC: G01S13/931
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To provide a durable, lightweight radar lens antenna which is suitable for the setting of a missile, and makes a fast scanning and has an unlimited range of consideration. SOLUTION: A radar lens 14 is formed of a conventional Fresnel lens 10, but a stepwise similar body in, preferably, three stages substitutes for a conventional curved surface. The thickness of the stepwise lens 14 of each step is a half or plural halves as large as the radar operation frequency at a halfway position of the lens 14. This lens 14 is thin enough (therefore lightweight enough) to quickly move laterally by, preferably, a combination of cams 42 and 52 and springs 44 and 54. Consequently, an extremely fast scanning can be made only in a limited visual field. When the lens 14 and feed horns 46, 48, and 50 are all supported by gimbals, the scanning becomes slow, but the range of consideration is unlimited.

IPC: G08G1/09
Filed: 1983-02-18
Abstract: PURPOSE:To obtain a system receiving surely traffic information containing in plural radio broadcasts by changing over a frequency dividing ratio of a PLL. CONSTITUTION:A radio signal received by an antenna 4 is given to a tuner 6 listening to a desired radio broadcast and a tuner 7 listening mainly to traffic information via a branching circuit 5. A signal demodulated by each tuner is outputted as sound from a speaker 13 via a changeover switch 8. A PLL6f receives a signal deciding a frequency dividing ratio from a line 15 and an oscillated frequency from a local oscillator 6b is frequency-divided by a frequency-division circuit 6g. A receivable tuning frequency is changed and plural radio broadcast stations are selected by comparing the frequency-divided signal with a reference frequency signal and making them coincident with each other. The frequency dividing ratio of the PLL is changed by a time sequential signal generated from a control means and when traffic information is included at the scanning of receiving, it is received.
