Title: Broadcasting system discrimination device
Inventor: KUNIHIRA TADASHI
IPC: H04N7/00
Filed: 1988-01-19
Abstract: PURPOSE:To precisely discriminate a broadcasting system with simple constitution by measuring only the cycle of a vertical synchronizing signal with the aid of using a reference clock signal and discriminating the broadcasting system of an NTSC/PAL system when the cycle is over a second threshold value. CONSTITUTION:When the VSS signal is inputted from an input terminal 3, a flag is set to a flag register 4 and simultaneously to that, the count value COUNT 1 of a round type counter 2 at that time is fetched by a latch circuit 5. Besides, as the count value of the counter 2 when the VSS signal one before is inputted is stored in the area of an address called a COUNT zero in an RAM 7, the cycle of the VSS can be obtained. The 90% of the reference cycle of the VSS signal of an NTSC system is stored in an ROM 8 as a second threshold value (the THR 2), it is judged as noise when the cycle of the VSS signal is below the THR 2, the discrimination of the broadcasting system at that time is stopped and the average value of the count value of the counter 2 corresponding to the reference cycle of the VSS signal is made to be a first threshold value (a THR 1) for the discrimination of the broadcasting system.

Title: Synchronous wind generator
Inventor: LEVINS NIKOLAJS
IPC: H02K21/26
Filed: 2016-12-09
Abstract: The invention relates to electromechanical industry, particularly to synchronous electric machines with excitation from the permanent magnets, which are widely applied for the small and medium power wind generators. A synchronous wind generator with excitation from permanent magnet and with concentrated armature winding (tooth coil) is proposed (fig.3). Differences of proposed generator's construction from well-known constructions are the following: number of generator's stator teeth is proportional to doubled phase number of the armature winding and for the generator's poles is one common divider which is equal to 2. Besides the difference of stator teeth and rotor pole number is equal to 2. The proposed wind generator is recommended to be produced with multiphase execution, i.e. with a number of phases which is larger than 3. Fulfilling all the above constructive peculiarities, generator has a significantly reduced teeth braking torque between the stator teeth and the rotor poles, which provides a wind generator starting up at lower wind speed. At the same time an increase of wind generator's power density and capacity of utilization rate, as well as reliability and lifetime resource is provided.
