Title: Printing missing detection system
Inventor: NAKAHARA AKIRA
IPC: B41J7/96
Filed: 1978-10-16
Abstract: PURPOSE:To prevent the missing of printing due to the decrease, etc. of printing pressure in case of hammering by a simple circuit, by detecting the missing of printing, etc. by detecting the change of resistance value at the conductive rubber being buried in a platen. CONSTITUTION:Conductive rubber RB, which resistance value changes by printing pressure, is buried in a platen PL. A type head HD is struck to the platen, characters are printed to a blank form PP through an ink ribbon and the resistance value of the conductive rubber RB alters by printing pressure in case of printing. The variation of the resistance value is expressed as the alteration of terminal voltage at the both end of the conductive rubber RB, and the terminal voltage at the both ends of the conductive rubber is input to one side input terminal of a comparator COM through an amplifier AMP, and compared with reference voltage Vr.

Title: Color television camera
Inventor: NAKAYAMA MASAAKI
IPC: H04N9/68
Filed: 1979-10-01
Abstract: PURPOSE:To increase the saturation of a specified color without affecting greatly the reproducibility of other colors for the frequency separation type signal-tube color TV camera, by securing the differenct gains between the plus and minus sides of the color difference signals. CONSTITUTION:Only the signals of the plus side are selected by the minus-side clipping circuit for the color difference signal R-Y obtained through the subtractor 6, and then amplified by the amplifier 8 having the amplification factor A1 to be led to the adder 15. On the other hand, only the signals of the minus side are selected for the signal B-Y led to the plus-side clipping circuit and amplified by the amplifier having the amplification factor A1' (A1'>A1) to be led to the adder 15. Then the signal R-Y having a large gain of the minus side compared with the gain of the pluse side is obtained at the output of the adder 15. Thus only the gain of the minus side of the R-Y signal is increased compared with the NTSC system, and as a result the saturation of the green is increased. And accordingly, the number of the colors to give an effect to the color reproduction is reduced. In such way, the saturation of the green color can be increased without giving any effect to the reproducibility of the flesh color.

Title: Quick disconnect coupling for hydraulic control system integrated with damper
Inventor: NIX RICHARD ANDREW
IPC: B60T17/04
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To damp hydraulic pulsation within a system by providing inside one of the quick disconnect coupling member a surface that communicates with hydraulic fluid passage means of one of the coupling members, and further disposing a diaphragm that responds to the pulsation of the hydraulic fluid inside the conduit assembly. SOLUTION: A diaphragm 72 is disposed inside a main body of a female coupling member 44. An inner surface 72c of the diaphragm 72 fluidly communicates, through a bore 56a of a disc, with hydraulic fluid which moves via a hydraulic passage that is defined in the female coupling member 44 by a center axis passage 54d and a radial passage 54i. With this construction, the diaphragm 72 weakens the vibration of the hydraulic fluid or the pulsation transmitted from a crankshaft to a clutch pedal. Consequently, the beating of the pedal and the beating of the clutch pedal are minimized or eliminated. At the same time, the vibration felt by a driver from the clutch pedal is eliminated or minimized.

Title: Image blurring preventing adaptor device for camera
Inventor: NAKAZAWA ISAO
IPC: G03B5/00
Filed: 1990-05-16
Abstract: PURPOSE:To automatically execute an operation responding to the operation of a camera side without applying no load or change to the camera side by controlling the action of an image blurring preventing means in response to a detecting means for detecting a change in the outside of a camera. CONSTITUTION:A variable apex angle prism is used as a correcting optical system 401 to be driven so as to correct image blurring based upon the information of blurring detecting means 1 to 7 arranged on a blurring preventing adaptor. When an angular deflection in a yawing direction is generated in a video camera body, the video camera photographs a direction deviated from a normal state by a certain angle and light beams (a) to (c) form an image on a point Q of an image face 407, so that the obtained image is blurred. Thereby, the deflected variable of the video camera is detected by the angular deformation detectors 1 to 7, a front side glass plate 402 is rotated around an axis 402a by a driving device (e.g. a voice coil) based upon the detected variable so as to offset the angular deflection and the beams are bent by prism action to form the image on the original point P. Consequently, image blurring preventing action can be executed without forcing a photographer to execute complex operation.

Based on these data, the positional relationship between the position of the probe 1 and the position of the specified shape part of the body to be inspected is operated in an operating means 14. The electronic scanning position of a monitor line and a beam path for monitoring the contact state between the probe 1 and the body to be inspected are determined. Based on the determined monitor line and a flaw detecting line, the direction of the ultrasonic wave beam and the focusing position are set again, and the flaw detection is performed. The echo data at that part are collected and recorded as the flaw detection data. The means 14 performs operation in order to determine whether the data agree with defect judging conditions or not. When the data agree with the conditions, the data are outputted to the outside though an output means 15.
