Title: Video signal processing circuit
Inventor: MOTOKI SATORU
IPC: H03H15/00
Filed: 1990-09-05
Abstract: PURPOSE:To eliminate need for a level adjustment by allowing a gain control circuit to adjust the gain with a DC voltage in response to a difference of signal levels so that a 1H delay video signal and a video signal not delayed have an equal level. CONSTITUTION:One of input video signals is fed to a one-horizontal period delay circuit 1 and the other is fed to an adder circuit 6. The level of a one- horizontal period delay video signal (1H delay signal) outputted from the one- horizontal period delay circuit 1 is adjusted by a gain control circuit 2 and added to a video signal not delayed at an adder circuit 6. A detection circuit 3 detects the level of the 1H delay signal and a detection circuit 4 detects the level of the signal not delayed. These signals are fed to a comparison amplifier 5, and a level difference signal obtained from the comparison amplifier 5 is fed to the gain control circuit 2. Then the comparison amplifier 5 adjusts the gain so that the level of the not delayed signal and the level of the 1H delay signal are equal to each other in this way. Thus, the adjustment of the addition/subtraction of the not-delayed signal and the 1H delay video signal in a comb-line filter is not required.

Title: Cylinder piston structure for internal combustion engine
Inventor: MORI JINPEI
IPC: F01B9/06
Filed: 1988-09-16
Abstract: PURPOSE:To omit a crank shaft and enable reductions in size and weight by rotating a piston once every its reciprocating motion with an elliptic endless piston guide channel on the cylinder inner circumference as a track. CONSTITUTION:When a piston 2 carries out a general reciprocating motion as an internal combustion engine, the guide protruded part 4 on the outer circumference of the piston 2 is moved along the piston guide channel 3 on the cylinder 1 inner circumference. Hence, the guide protruded part 4 draws a rotation locus with the elliptic endless piston guide channel 3 as a track, so that the piston 2 is rotated once every its reciprocating motion. The piston rotation can be direct transmitted to a motor shaft 5. Thus, as a crank shaft requiring a wide rotating space is omitted, further reductions in size and weight of the internal combustion engine can be achieved.

Title: Method and device for controlling electronic beam quantity of image pickup tube
Inventor: SATO KAZUHIRO
IPC: H04N5/228
Filed: 1985-10-21
Abstract: PURPOSE:To execute a stable ABO control by operating the 1st lattice electrode at a positive voltage with respect to a cathode and applying a voltage signal corresponding to a return beam from a photoconductive target to the 2nd lattice electrode of an image pickup tube. CONSTITUTION:A beam current out of the cathode 1 of the image pickup tube 10 is absorbed by the 1st and 2nd lattice electrodes 2 and 3, and some of said current turns out to be a scan beam current IB. Some part of the scan beam current becomes a return beam current IR on a photoelectric conversion surface 11, and is absorbed by the 2nd lattice electrode 3. A resistance 20 inserted between the cathode 1 and an earth detects the voltage signal corresponding to the scan beam current, and simultaneously a resistance 12 converts a signal current taken out of the photoelectric conversion surface 11 into a voltage so as to detect. The signals detected by the resistances 12 and 20 are added by an adder circuit 21 to obtain a signal voltage VR corresponding to the return beam current. After a signal showing the difference between the signal voltage and a reference voltage 22 is amplified by an amplifier 23, it is applied to the 2nd lattice electrode 3, thereby executing the stable ABO control.

Title: Etching method
Inventor: SHIMIZU AKINORI
IPC: H01L21/308
Filed: 1984-11-06
Abstract: PURPOSE:To form good contacts between wiring layers with good yield even in very fine contacts in a semiconductor IC, by using a specific etchant. CONSTITUTION:The addition of a non-ion activator to an etchant made mainly of phosphoric acid is used as the etchant. When this etchant is used, an aluminum oxide film 6 on the first wiring layer 3 can be completely removed because of filling a contact hole 5 with the etchant. This results in good contact of the first layer wiring 3 with the second layer wiring 7. Such a use of an acid etchant with the addition of an acid-resistant non-ion activator which improves wetting without giving bad effects on semiconductor elements allows the etchant to sufficiently infiltrate into and fill contact holes even with diameters 5-1mum, and the remaining oxide film to be completely removed.

IPC: G05B13/02
Filed: 1984-11-06
Abstract: PURPOSE:To reduce the variance of a controlled variable from its target value and to improve the control performance of a compensator in terms of the function of the load, by adding the deviation amount and the value obtained by playing said deviation amount and applying this value to a PID controller to a compensator to obtain a manipulated variable. CONSTITUTION:The controlled variables 13 and 14 of a controlled system 11 are varied when a load 12 has fluctuations. These controlled variables 13 and 14 are applied to subtractors 17 and 18 for acquisition of difference from target values 15 and 16. These differences are applied directly to adders 21 and 22 as well as to compensators 27-30. Then said differences are added with compensation outputs of other loops by adders 31 and 32 and then applied to adders 21 and 22 for addition. The gains and scales of compensators 27-30 are set to be equal to the function of the load 12. Thus both a minor loop and the inter-loop interference are compensated. As a result, even a big change of the characteristics of the controlled system 11 caused by the fluctuations of the load 12 can be followed up.
