Title: Picture signal recording and reproducing device
Inventor: SASAKURA TAKAO
IPC: H04N5/335
Filed: 1990-03-07
Abstract: PURPOSE:To output a picture signal not to generate carrier leak by subtracting a signal corresponding to an optical black part, which is provided at an image pickup element, from the other signal in the storing operation of a picture memory on a reproducing side. CONSTITUTION:A correcting circuit 4 subtracts the signal corresponding to the optical black part, out of digital picture signals read out from a picture memory 3, from the other signal digitally and therefore, the level fluctuation of the picture signal caused by a clamp processing on a recording side is digitally corrected. Then, the corrected digital picture signals are reloaded with digital picture signals stored in the picture memory 3. A memory control circuit 7 successively reads out the level-corrected digital picture signals stored in the picture memory 3, and those picture signals are converted to analog picture signals and afterwards outputted from an output terminal 6. Thus, the carrier leak to be generated at an image pickup part and the picture signal not to generate the carrier leak can be outputted.

Filed: 1989-03-06
Abstract: PURPOSE:To make it possible to be influenced by noises with simple constitution by detecting magnetic saturation by the magnitude of rectangular wave voltage induced on the secondary side of a high-frequency transformer. CONSTITUTION:A voltage detector 8 detects the alternating voltage of a rectangular wave induced in the secondary winding of a high-frequency transformer 5, and a signal rectifier circuit 12 rectifies it into rectangular wave voltage. Then, a waveform shaping circuit 16 slices the amplitude of this signal at a constant level changing it into a pulse signal having suitable amplitude. An insulating circuit 16 insulates this pulse signal and the first integrating circuit 14 integrates the signal generating an analogous signal VTN being proportional to the pulse width of the pulse signal. The second integrating circuit 15 integrates the output signal of an drive circuit 11 to attain an analogous signal Vtn being proportional to the pulse width. A comparator 10 compares the signal VTN with Vtn, and issues a stop command to the inverter circuit 11 judging that magnetic saturation occurs when VTN<Vtn has been fulfilled.

IPC: H01L21/66
Filed: 1989-03-07
Abstract: PURPOSE:To enable the avoiding of complication of a wire connection for output signals by detecting an output signal of an IC to be tested optically. CONSTITUTION:When a pattern signal generator 1 supplies an input signal to an IC 4 to be tested on a burnin board 3 through a connector 2, an image detector 6 detects a flashing condition of a light emitting element 5 connected near an output terminal of the IC 4 and outputs an image signal thereof to an image comparator 7. On the other hand, the generator 1 outputs expected output signal information as expected for IC 4 to an image generator 8, which 8 generates expected image information from the information. The comparator 7 compares the image information with an image information detected. When they do not coincide, an output terminal of the IC 4 involved in the noncoincidence and a timing thereof are specified. This eliminates the need for drawing an output signal circuit through the connector 2 thereby enabling the avoiding of complication a connection wire with the cutting thereof.

Filed: 1985-03-20
Abstract: PURPOSE:To effectively form a thin film having good quality with a small amt. of gaseous raw materials by introducing the gaseous raw materials into a reaction vessel only for the prescribed time correspondent to the time since the gaseous raw materials receive the irradiation of light until active seeds are generated and form the thin film by reacting relatively with a substrate.

The WF6 is introduced from the solenoid valve 9 of the substrate 14 and the H2 from the solenoid valve 8 existing near an irradiation window 12 respectively into the vessel 10. The substrate 14 is kept heated to 400 deg.C by a heater provided to a stage 13 during this time. Laser pulse light is irradiated into the reaction vessel upon turning off of the gate pulses of the respective solenoid valves. The laser irradiation is stopped when the film of W is formed up to a prescribed film thickness. The thin W film formed in such a manner exhibits the high purity and specific resistance equal. to or better than the purity and specific gravity of the thin film formed by the conventional CVD method. The efficient formation of the thin film at a high speed with a small amt. of the gaseous raw materials is thus made possible.

Abstract: PURPOSE: To considerably reduce the load that is applied to a tool even when an obtuse angle part of a work is cut or ground at a comparatively high speed by the tool based on the two-dimensional scanning of two axes of a 3-axis NC machine tool with another remaining axis kept fixed. CONSTITUTION: The three-dimensional NC data showing the three-dimensional position data on each of points existing between a start point Q1 and an end point Q8 related to the two-dimensional scanning are extracted out of the three- dimensional NC data which are previously prepared. Then it is decided whether the angle θformed by the locus of a tool 1 that is decided from the NC data on three continuous points out of those extracted NC data is obtuse or not. If an obtuse angle is confirmed, an obtuse angle part that is specified by the NC data on three points Q6 , Q7 and Q8 forming an obtuse angle as an approximate circular arc is converted into the NC data on eight points Q6 , d, e, f, g, Q7 h and Q8 which is closely approximated into the circular arc with five points.
