Title: Magnetic recording and reproducing apparatus
IPC: G11B15/467
Filed: 1989-12-05
Abstract: A magnetic recording and reproducing apparatus for 
performing automatic tracking in a video tape recorder of a 
helical scan type. A magnetic head is wobbled by an 
electromagnetically driven actuator in a transverse 
direction of a recording track, a tracking error signal is 
obtained by extracting a signal component attributable to 
this wobbling from a signal reproduced by the magnetic head, 
and the extracted signal component is fed back to the 
electromagnetically driven actuator. By setting the 
magnetic head width to 1 - 1.5 times the recording track 
width, a dead zone is made small, and the tracking error 
signal is obtained positively. In addition, by setting the 
frequency for driving the electromagnetically driven 
actuator at a level between a primary resonance frequency 
and a secondary resonance frequency and by subjecting the 
driving frequency to phase conversion, the driving frequency 
is converted into a high frequency to permit highly accurate 
tracking. Furthermore, any deviation in the tracking by a 
fixed magnetic head caused by a DC current and the like is 
prevented by extracting a low frequency component containing 
a DC component from the tracking error signal and by feeding 
back that extracted signal to a capstan motor for driving a 
magnetic tape.

Title: Sample data transmission apparatus
IPC: H03M13/27
Filed: 1990-07-26
Abstract: In a sampled data transmitting apparatus in which the sampled data to be transmitted are divided into odd-numbered samples and even-numbered samples and arranged in different rows of a two-dimensional data array, and in which error correction codes are annexed to each row and to each column of the two-dimensional data array, the row arraying sequence in one of the odd-numbered or even-numbered rows is caused to differ from the row arraying sequence in the other of the odd-numbered or even-numbe red rows so that odd-numbe red data and even numbered data continuous with the odd-numbered data are not arranged in one row. In this manner, even when the error correction becomes unfeasible by the error correcting code for one row, interpolation becomes feasible because there exist no odd-numbered data or even-numbered data continuous to each other in the row.

Title: Poppet valve and valve assemblies utilizing same
IPC: F15B13/04
Filed: 1992-02-07
Abstract: In a housing, there is formed, in series, a first end cavity, a first cylinder cavity, a pressure cavity, a second cylinder cavity and a second end cavity. The cavities are separated by walls which include orifices. Two identical valve members are located in the housing. The first valve member has a piston and a valve plug in the first end cavity and a valve plug in the pressure cavity. The second valve member has a piston and a valve plug in the second end cavity and a valve plug in the pressure cavity. Pressure in the pressure cavity acts on the confronting ends of the two valve members. A two position control rod, in a first position, connects pressure to the piston in the first end chamber and connects the second end chamber to return. The piston has a larger area than the second end of the valve member, creating a force differential which moves the first valve member endwise inwardly. Pressure acting on the second end of the second valve member moves it endwise outwardly. The same control rod, in it's second position, connects the second piston with pressure and the first piston with return. Pressure acting on the second end of the first valve member moves it endwise outwardly. Pressure acting on the second piston moves the second valve member endwise inwardly. Such movement of the valve members moves the valve plugs to open and close orifices in the separator walls, to switch pressure and return between two paths leading from the valve assembly. <IMAGE>
