Title: Geared pulley for geared belt transmitting mechanism
Inventor: TOKORO HIROJI
IPC: F16H55/38
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To sufficiently reduce the noise without lowering the transmitting ability and the lifetime of a belt by opening an air flow passage such as a groove or a hole, which is communicated with outside, in a bottom surface of a gear groove, not in a side surface of a gear. SOLUTION: Since a bottom surface of a tooth groove 21 is formed with a groove 22 in the gear cross direction so that the bottom surface of the gear groove is communicated with outside, resistance of the outside air, which is flowed into between a tooth crest of a belt and a bottom surface of a gear groove of a pulley is reduced, and the compressed air to be left between the tooth crest of the belt and the bottom surface of the gear groove of the pulley is eliminated so as to reduce the noise. In a gear side surface of the pulley, an air flow passage such as a groove and a hole is not provided, and the power transmitting area of the gear side surface of the pulley and the gear side surface of the belt are not reduced so as to prevent the lowering of transmitting ability and the lifetime of the belt. Consequently, noise can be sufficiently lowered without lowering the transmitting ability and the lifetime of the belt.

Title: Automatic tracking device for magnetic recording and reproducing device
Inventor: SEKIYA MASATAKA
IPC: G11B15/467
Filed: 1990-05-18
Abstract: PURPOSE:To automatically acquire the most suitable tracking state by separating a synchronizing signal from a video signal regenerated from a rotary video head and adjusting automatically a tracking amt. with a synchronous disturbance in the synchronizing signal. CONSTITUTION:The video signal regenerated by the rotary video heads 1 and 2 is inputted from an amplifier 11 to a signal processing circuit 16, and from a demodulated signal, the synchronizing signal is detected. A period of the signal is measured by a synchronization detecting circuit 18, where a variable amt. in the same field is detected, and this variable amt. is compared with a variable amt. of the previous field to be determined as either of two large and small values and then the determined value is outputted to a tracking adjusting circuit 20. A direction of tracking correction is determined by the circuit 20 according to the large or small size of the variable amt. detected by the circuit 18, and hence a tracking amt. is increased or decreased in the direction of diminishing a synchronous variation. Then, the state of the least amt. of jitters is discriminated by a discriminating circuit 19. By this method, the most suitable tracking is obtained automatically.

IPC: G01R31/08
Filed: 1982-07-22
Abstract: PURPOSE:To curtail expense with a better accuracy by arranging an oscillator in a measuring apparatus for relative processing of two or more input signals to enable synchronization with one or more input signals so that two or more input signals are normally allowed to be relatively processed with output of the oscillator as simulation signal by synchronization thereof at a fixed interval. CONSTITUTION:A portable DC ground-fault point detector is provided with an oscillator 8 the same in the frequency as that of an earth voltage E0, which is to be synchronized with the earth voltage E0 through a synchronization wire 7. After the establishing of the synchronization, the wire 7 is removed and a relative processing is done with the output of the oscillator 8 as simulation signal of the earth voltage E0. This eliminates the need for constant connection of the synchronization wire 7 allowing free use of a portable DC ground-fault point detector at a desired location. The same effect can be obtained when using a wireless signal or a signal through a searh coil 13 utilizing a lead wire 6 in place of the synchronization wire 7. This method enables a relative processing without connection of all input signals.
