Title: Video camera automatic focus system
Inventor: ITO SHOSAKU
IPC: H04N5/232
Filed: 1990-01-30
Abstract: PURPOSE:To attain focusing to a posing closer to a major object by setting a threshold level to an integration device when a high frequency component is extracted from a luminance signal of a video signal and the detected output is integrated and selecting the detected output for the integration depending on the threshold level. CONSTITUTION:A luminance signal of an image formed to an image pickup element is inputted to a high pass filter 1 and only a high frequency component of the luminance signal is extracted. The high frequency component of the luminance component is inputted to an amplifier 2 and amplified up to a proper level. The amplified high frequency component is given to a detector 3, in which the absolute value is detected. The output of the absolute value is integrated by an integration device 4 and a focus signal is outputted. The integration device 4 applies one field integration to only the absolute value output higher than the threshold level given from a threshold level generator 5. The threshold level generator 5 decreases the threshold level when the focal signal is small and increases the threshold level when the focus signal is saturated. Thus, the property of the focal signal is changed by the user in matching with an object.

Title: Inclined cross-section cutting in sheet material cutting
Inventor: SAOTOME MOTOHIRO
IPC: B26D5/00
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To attain high dimensional accuracy and a cut part with a good ridge line by operating a DC servomotor for controlling a cutter based on a command from a CPU for X, Y and θ axes as cutter control, and supplying a pulse train from the CPU for controlling a Z-pulse motor for Z axis. SOLUTION: This device is constituted of a table, an X rail, a cutter head and so on. For cutting work, a cutter is moved to a prescribed position (1), a start command is given to a Z pulse motor (2). After delay time passes, a position command is outputted to a DC servomotor to move it along the ridge line of an inclined cross-section ((3), (4), (5)). After, that, the cutter is moved toward a cutting end point, and is raised toward the upper part of a ridge line by giving an up start command to the Z pulse motor on this side of an end point which is set in the CPU (6). After the cutter has reached at the cutting end point, the DC servomotor for controlling X, Y and θaxes is stopped (7), which becomes an end. It is thus possible to conduct cutting of the inclined cross-section.

Abstract: PROBLEM TO BE SOLVED: To secure a wide dynamic range, and to lower a power voltage by composing a full wave rectifying circuit of a first rectifying circuit and a second rectifying circuit. SOLUTION: The input signal of an input terminal 6, for example, appears in the output of a noninversion amplifier circuit 1.

Title: Manufacture of hot galvanized steel plate subjected to alloying treatment
Inventor: TANAKA MITSUO
IPC: C23C2/28
Filed: 1980-02-22
Abstract: PURPOSE:To manufacture an alloy-hardened hot galvanized steel plate without causing melting damage to hot galvanizing pot, etc., by heating molten zinc prior to discharge when applying hot galvanization to the surface of a steel plate by discharging the molten zinc from a molten zinc exhaust device. CONSTITUTION:A steel plate 3 coming out of a pretreatment furnace 4 is introduced through a sealing device 5 into a hot galvanizer 1 confined with a nonoxidative gas, where it is then hot galvanized with molten zinc discharged from the molten zinc exhaust device 7. In this case, the molten zinc is heated to 440-800 deg.C by a heater 9 on its way toward the exhaust device 7 through a pump 8 from a molten zinc tank 2, blown against one side of the steel plate 3, and then blown off its excessive molten zinc adhered by means of a gas wipe nozzle 12. Then, the hot galvanized steel plate is subjected to an alloying treatment in an alloying furnace 11 where alloying occurs between the plated zinc and the steel plate to further raise the corrosion resistance of the hot galvanized surface. Since the molten zinc is raised in its temperature immediately before spraying, no damage to galvanizing pot occurs because the temperature inside the galvanizing pot is low.

Title: Semiconductor optical switch
Inventor: KAWAGUCHI HITOSHI
IPC: G02F1/03
Filed: 1982-02-12
Abstract: PURPOSE:To eliminate the need for holding electric power for the purpose of holding a switch state, by forming a thin film consisting of a ferrodielectric substance on optical waveguides and using the electric field in the semiconductor optical waveguide generated by the residual polarization of the ferrodielectric substance as an electric field for switching. CONSTITUTION:When negative voltage is applied to an electrode, polarization is generated in a ferrodielectric substance layer 4, and a depletion layer is generated in an optical waveguide layer 2 for forming semiconductor optical waveguides. As a result, the concn. of carriers decrease and the refractive index of  the layer 2 changes. The propagation constant of the voltage-applied layer 2  changes with said change in the refractive index, and the optical coupling between two optical waveguides A and B changes, whereby a switching effect  can be obtained. Even if the voltage is removed, the residual polarization remains in the layer 4; therefore, the electric field in the semiconductor is held as  it is, and this state is maintained until the voltage of a reversed polarity is next  applied.

As a result, the phase of the horizontal synchronizing signal recorded by the heads 7, 8 does not cause any discontinuous part on the tape and the skew distortion produced between tracks is corrected.

Title: Phase demodulating device
Inventor: UMEDA KEISUKE
IPC: H04N7/00
Filed: 1993-02-09
Abstract: PURPOSE:To enable an another system automatic switching function having a simple constitution by generating a control signal, which is required for switching of the constitution of a phase demodulating circuit, in a block in the succeeding stage which uses the signal obtained by the phase demodulating circuit. CONSTITUTION:When a modulated signal S1 of the B/G system is inputted to the phase demodulating circuit where the initial state corresponds to the I system, a reproduced data signal S5 is meaningless because a QPSK phase demodulating part 10 processes the signal SI as that of the I system. Though the signal S5 is inputted to a PCM decoding part 20, a synchronous detection part 21 of this part 20 brings about synchronous error to out put a synchronous error pulse S7. This pulse 97 is monitored for a certain time by a counter part 23 to discriminate chat the error is caused by the difference of setting of the demodulating part 10 in the preceding stage. Then, a setting change pulse S9 of the demodulating part 10 is outputted. The demodulating part 10 receives this pulse S9 to control the change of its own various parameters, and the phase demodulating circuit adapted to the B/G system is constituted.

In the case when the incorporated matter is assembled by screws, it is disjointed by the screw-removing means 2 and the manipulator hand 5. Next, the detector 1 is sent in the direction X by the chucking mechanism 6a and a hollow outer-tube part wherefrom the incorporated matter is extruded is cut off and put in an accommodating tube 9. By this constitution, exposure is prevented and a volume is reduced by incineration and compression.
