Title: Pulse noise eliminating circuit
Inventor: OI SHINICHI
IPC: H04N7/20
Filed: 1985-03-30
Abstract: PURPOSE:To prevent an edge of an input signal from being unsharpened at a weak electric field by operating a filter part of a median filter section when the number of pulse noises is a prescribed value or over to eliminate the pulse noises. CONSTITUTION:A pulse noise detector 102 detects the number of pulse noises superimposed on a signal part of a field blanking with a prescribed level. When the number of pulse noises is less than a prescribed level, an output S goes to a low level and when the number of pulse noises is the prescribed level or over, the output S goes to a high level. When the output S of the pulse noise detector 102 is at the low level, a selector 100 selects an input signal A1, and when at the high level, the selector selects a signal A2. Thus, when the input signal is excellent especially, an output signal is obtained without unsharpening the substantial signal edge.

Filed: 1981-05-06
Abstract: PURPOSE:To facilitate the working, by faying both ends of a hoop by welding after materials where the section has an apprximately T shape are molded to a shape like a hoop and working this hoop plastically in case that a rim having a ring-shaped faying part on the inside circumferece is produced. CONSTITUTION:Linear rim blanks 11 where the section has an approximately T shape are constituted by the extrusion of, for example, of light alloy materials and are cut to a required length corresponding to a finish rim diameter. If blanks 11 are constituted specially continuously by the extrusion, the mass production is possible, and the yield of materials is improved considerably, and homogeneousness is realized. After cut blanks 12 are molded to a shape like a hoop so that a projecting stripe 13 is inside, faces to be matched to each other of blanks 12 are welded. In this case, since a diameter (h) of blanks 12 in the direction of thickness is small comparatively and the welding region is only the flat surface part, the working is very easy. The part of blanks 12 orthogonal to the projecting stripe 13 is molded by rolls 14 and 15, which have required inside and outside shapes and face to each other, while rotating blanks 12, thus working plastically blanks 12 to a prescribed shape.

Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To regulate the humidifying time and the drying time by providing heaters for heating an object on a belt conveyor disposed in boxes above the carry-in port and the carry-out port. SOLUTION: When the humidifier/heater is used as a humidifier, an infrared heater 424 is not used and the temperature is kept at such a level as the vapor is condensed. In this regard, water in a water storage tank is heated up to a specified level by conducting a water temperature regulating heater 421 and the vapor pressure is increased. At the same time, a stirrer mechanism 422 is operated to stir the water thus making uniform the water temperature. On the other hand, a plate heater 425 is conducted to heat the wall surface in the upper space thus preventing the water on the wall surface in the upper space from being condensed and dripped under high humidity. When the humidifier/heater is used as a dryer, water in a water storage tank 406 is drained.  The water temperature regulating heater 421 and a dew formation preventing heater 425 are not used but the infrared heater 424 and a plate heater 423, as the case may be, are conducted in order to dry a molding M on a carrier sheet 1.

Abstract: PURPOSE:To prevent the wrong input of information owing to an inadvertent operation by permitting an input action of an operation input means only in case an input pen has a contact with another member and no input of coordinates is carried out by the input pen. CONSTITUTION:When an input pen 2 has a contact with an input tablet 1 and the input of coordinates is carried out, a pen switch detecting circuit 4 outputs logic level '1' and a coordinate input detecting circuit 3 sets a signal that is not indicating the coordinates at logic level '0'. Thus, the output signal of an AND gate 7 is set at logic level '0' together with the output signal of an AND gate 6 set at logic level '0' regardless of the operating state of a key switch 5. While the output signal of the circuit 4 is set at logic level '1' while the pen 2 is put into a pen holder and kept at pause. Furthermore, the circuit 3 sets the signal indicating no coordinates at logic level '1' and therefore the output of the gate 7 is set at logic level '1'. Under such conditions, the logic level '1' showing the operation state of the switch 5 is outputted to a processing circuit via the gate 6 with operation of the switch 5.
