IPC: C23C14/52
Filed: 1980-05-20
Abstract: PURPOSE:To safely observe the position of electron beams irradiated with high work efficiency by attaching light dimming filters capable of regulating the quantity of light to the front of the external viewing window of an airtight chamber. CONSTITUTION:Light dimming filters 7, 8 are attached to the front of the external viewing window 6 of an airtight chamber 2 with filter-fitting metallic parts 9, and the deposition of a depositing material on the glass of the window 6 is prevented by a shielding plate 5. The position of electron beams irradiated in a crucible 4 can be confirmed by reflection with a reflecting mirror 3 as shown by a seeing direction 10. In accordance with the quantity of an electric current for electron beams the filter 7 alone is used, or the filters 7, 8 are superposed to suitably select the light transmittance. Thus, the position of electron beams irradiated can be observed with accuracy, and the danger of injuring eyes can be eliminated perfectly.

Title: Moving picture compression-encoding device
Inventor: OUTA MINORU
IPC: H04N19/60
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To suppress the increase of a generation code amount when scene change is generated and to improve picture quality by providing a selection means for directly introducing the video signals of a frame immediately after the scene change passed through a second filter to an orthogonal transformation means when the scene change is detected or the like. SOLUTION: When a scene change detection circuit 3 detects the scene change, scene change detection signals are outputted to a selection circuit 8 and the output of a filter 7 whose upper limit value of a pass band is lowest is selected. The output video signals of the filter 7 selected when the scene cange detection signals are inputted by the selection circuit 8 are the frame immediately after the scene change. Thus, the video signals of the least information amount are selected in the selection circuit 8 and inputted to a subtraction circuit 9. Also, when the scene change detection circuit 3 detects the scene change, a switch 18 is opened, the video signals passed through the filter 7 are supplied to an orthogonal transformation circuit 10 and quantization is performed in a quantization circuit 11 for an obtained coefficient.

Abstract: PURPOSE:To increase the access speed to an aiming information by carrying out an error check after recording an information, recording the mark of no error in case of no error, carrying out the error check again at the time when the information is reproduced and adding the mark of the presence of an error in such case. CONSTITUTION:An error check is executed after recording an information on an optical card 1 and a V mark is recorded when no error existing on an information track is confirmed. At the reproduction time an optical spot is moved toward a point 901 from point 900. A V mark 90V is first detected and after confirming no E mark presence in succession an information 90D is reproduced. Thereafter, the optical beam carries out an error check with moving to L direction by reversing at the point 901. In case of the error presence an E mark 90 is added. The reproducing speed is thus made higher.

Title: Method and apparatus for operational amplifier with wide dynamic range
Inventor: JIYOSEFU WAI CHIYAN
IPC: H03F3/45
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To provide an operational amplifier which has a wide dynamic range and which can be used for the purpose of a low voltage level. SOLUTION: The operational amplifier having output to be inverted 20 from feedback voltage to line power voltage contains an amplifier stage 12, and a linear output invertor 14. The linear output invertor 14 contains an inversion reducing stage 16, an output stage controller 17 and a raising output stage 18. The inversion reducing stage 16 operates in such a way that output to be inverted is reduced to feedback voltage when output to be inverted is lower than a first threshold. The raising output stage 18 operates in such a way that output to be inverted is raised to line voltage when output to be inverted 20 is higher than a second threshold. Since the first threshold is larger than the second threshold, the inversion reducing stage 16 and the raising output stage 18 operate when the output to be inverted 20 is between the first threshold and the second threshold.
