Title: Signal processing system for y/c separation video signal
Inventor: FUJII NOBORU
IPC: H04N9/797
Filed: 1986-09-18
Abstract: PURPOSE:To reduce deterioration of picture quality even when dubbing is made many times by detecting phase difference between horizontal synchronizing signals extracted from reproduced luminance signals and chroma signals and forming vertical synchronization information for chroma signals. CONSTITUTION:Saw tooth wave SS of a saw tooth wave generator 12 is sampled by a sampling pulse M3that indicates nearly middle point of horizontal synchronizing signals H(C). The sampling voltage shows phase accuracy of a pair of rotary heads. Phase errors ERR obtained from a sampling hold circuit 13 are evened off by a smoothing circuit 16, and selected by switches S1,S2 for each A recording track and B track, and held by capacitors C1, C2. Thereby, it becomes possible to eliminate the problem of writing in different address even when phase error becomes large by dubbing of several times.

Title: Hysteresis inverter
Inventor: IWASAKI TOMONOBU
IPC: H03K19/0948
Filed: 1986-09-18
Abstract: PURPOSE:To vary the hysteresis output characteristic of an inverter by impressing a voltage to a gate of a 1st transistor (TR) and a common gate of the 2nd and 3rd TRs so that the 2nd and 3rd TRs are turned off/on when the 1st TR is turned on/off. CONSTITUTION:In pressing a voltage S1 is fed to an external terminal 6 of a hysteresis inverter, when the voltage V of the input signal is increased by a threshold voltage Vth3 of the TR 3 than the power supply Vss of a low potential, the TR 3 is turned on. In this case, the potential S1 fed to the external terminal 6 is divided by the resistances of the TRs 4 and 3 and the result is fed to the source of the TR 2. Then the TR 2 is not turned on until the input signal voltage V fed to the input terminal 7 does not reach the voltage V2 higher than the source voltage of the TR 2 by the threshold value Vth2. Then a low level signal E1 is outputted at an output terminal 8.

CONSTITUTION:The surface of a substrate 11 is oxidized in steam at 1100 deg.C to form an oxide film 12. Then, a silicon nitride film 13 is deposited on the oxide film 12 and then a silicon oxide film 141 is deposited on the silicon nitride film 13. This substrate 11 is joined to another substrate 15 which is oxidized for the surface only. The joined body is oxidized in steam at 1100 deg.C to have a good adhesion. After that, the joined body is exposed to a nitrogen atmosphere to adhere the substrates 11 and 15 firmly through oxide films 12, 141 and 142 and a nitride film 13. Next, the substrate 11 is ground from the side opposite to the substrate 15. After the distortion caused by grinding is eliminated by etching, the surface of the substrate 15 is polished again. Then, the device is subjected to the LSI process including element separation at 1000 deg.C or below to make a CMOS.

Title: Grinding wheel
Inventor: TSUJISATO YASUO
IPC: B24D5/06
Filed: 1986-09-17
Abstract: PURPOSE:To easily press a dust structure when it is molded, by constituting an abrasive grain layer of belt-shaped ring, tilting to the rotary axial line, so that the abrasive grain layer can be divided by a dividing surface almost perpendicular to the rotary axial line. CONSTITUTION:A pair of end part grindstones 10A, 10A and a central grindstone 10B are coaxially connected, and the two end part grindstones 10A, 10A are formed quite the same. In order to manufacture the end part grindstone 10A, having an abrasive grain layer 10A tilting at its one end surface, a metal mold is used as shown in the drawing. A bed metal 11A is mounted to be inserted into this metal mold, and a binding agent C, with which the periphery of the bed metal 11A is filled, is pressed. In said metal mold, it is only required to form the upper end surface of the filling binding agent C into an almost horizontal level, accordingly the binding agent C, easily performing its charge, enables a dust structure of uniform density to be molded. Similarly also in the central grindstone 12B, since both end surfaces of an abrasive grain layer 10B are almost vertical to the bed metal, the dust structure is molded further easier than the end part grindstone 10A. Accordingly, manufacture of a grinding wheel is easier than in the past.

Filed: 1991-08-29
Abstract: PURPOSE:To surely invert a transfer material upside down without trouble of jamming or the like so as to obtain high-quality pictures on both side with no stain due to stacking of toner powder by setting up a feed roller and a handling roller of the transfer material in a position with a different phase in the width direction of the transfer material. CONSTITUTION:A handling roller 5 and a press attached roller 5A brought into press contact with this roller 5 from below are positioned on a center line of width of a transfer material, and feed rollers 4 are arranged paired in a symmetrical position separated from the center line to provide an auxiliary roller 4A of diameter a little smaller than the feed roller 4 in a position corresponding to the handling roller 5. Accordingly, even when a slip is generated between the transfer materials by actuating the feed roller 4 to stick toner powder of the above positioned transfer material to an upper surface of the transfer material, the toner powder is not checked by the handling roller 5 but to pass through, and since press contact force is very small against the transfer material, in the auxiliary roller 4A, the toner powder is prevented from such as being generated from the transfer material.

Filed: 1988-09-01
Abstract: PURPOSE:To prevent a magnetic substance's clamping means itself from exerting an influence on magnetic flux passing through a pickup coil by setting up at least a part of the clamping means in a magnetic path of a signal rotor when a distribution rotor is clamped to the signal rotor with the clamping means such as a screw or the like. CONSTITUTION:When a signal rotor is rotated, magnetic flux passing through each of pickup coils 5 and 6 varies to some extent, and voltage conformed to a variation of the magnetic flux is outputted to a computer, whereby optimum ignition timing is determined. On the other hand, high voltage impressed on a center electrode 15 from an ignition coil is fed to a rotor electrode 15 via a contact piece 17, and it is discharged to a discharge gap A being formed when the rotor electrode 15 and a side electrode 12 are opposed to each other. In this case, at least a part of a screw 8 screwed in the signal rotor 4 is set up in a magnetic path of the signal rotor 4. Even in the case where the magnetic screw 8 is used, such a possibility that the screw 8 itself exerts an influence on a magnetic circuit is prevented from occurring.
