Title: Recording apparatus
Inventor: AKAHA FUJIO
IPC: B41J13/02
Filed: 1986-01-13
Abstract: PURPOSE:To obtain a recording apparatus having a mechanism certainly controlling the rocking of a platen, by rocking the platen with respect to a recording head by the cam having an axially symmetric shape formed on the lever revolving around the shaft provided in the vicinity of the central part of the platen. CONSTITUTION:A recording head 3, a transfer film 2 and recording paper 1 are pressed to a platen 4 by a spring 6 to perform desired recording. A rotary lever 13 rotates around a rotary shaft 12 by a motor 16 through a transmission lever 15 in a recording state and the high parts of two cams 14 formed on the rotary lever 13 push up both shaft ends of the platen 4 to stabilize said platen 4. At the time of non-recording, the rotary lever 13 rotates around the rotary shaft 12 as well by the motor 16 through the transmission lever 15 and the low parts of two cams 14 are contacted with both shaft ends of the platen 4 and, therefore, the platen 4 is necessarily moved downwardly under its own wt. Because the platen 4 is limited in its up-and-down movement and its operation other than rotation by the guide groove 11a formed to a frame 11, positional accuracy to the recording head 3 is accurate at both times of recording and non-recording.

Abstract: PROBLEM TO BE SOLVED: To provide a steel wire for arc welding excellent in wire feedability and having the stable welding performance by applying to the wire the lubricant of the prescribed quantity containing the prescribed quantity of dissolved fume powder of iron and steel in the base oil of vegetable oil, animal oil or mineral oil. SOLUTION: The lubricant containing 0.05-10wt.% of the dissolved fume powder is applied to a wire by the quantity of 0.2-2.5g per 10kg of the wire.

Title: Flow state detecting method for air current on surface of assembly of pedestal and installed body
Inventor: KOSHIHARA TOSHIO
IPC: G03B15/00
Filed: 1988-01-13
Abstract: PURPOSE:To easily detect the flow state of the air current on the surface of the assembly even when the structure of the assembly is complex by generating a temperature difference relatively between the surface of the assembly and air current. CONSTITUTION:The temperature difference is generated relatively between the surface of the pedestal 2, etc., of the assembly 1 and the air current 4 and while the air current 4 is blown to the assembly 1, a necessary place of the assembly 1 is photographed by an infrared camera 5 when the surface temperatures of respective parts of the assembly 1 become stale. Then when the surface temperature of the assembly 1 is held relatively higher than the temperature of the air current 4, the air current 4 on the surface of the assembly 1, i.e. the surfaces of the pedestal 2 and installed body 3 flows fast to cool the area where the air current strikes strongly more, thereby generating a temperature drop as compared with the area contacting said area. Here, the flow state of the air current 4 on the surface of the assembly 1 is detected in the infrared image on the surface of the assembly 1 by the camera 5 as the image pattern of a temperature distribution formed of a low and a high temperature area. Even when the temperature relation between the surface of the assembly 1 and the air current is reverse, the detection is performed similarly.

IPC: H04N1/047
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To highly accurately register images of a plurality of colors in a main scan direction and a sub scan direction by controlling an exposure timing of a scan optical system on the basis of a time interval value measured between a detection signal from an end position sensor or the like and an index signal from an index sensor. SOLUTION: An index sensor 312 senses beams reflected at a reflecting mirror 311 and outputs a current which is in turn converted to a voltage at an index detection circuit and output as an index signal. A plane position of a polygon mirror 305 rotating at a predetermined speed is detected from the index signal. Light scan by a modulation signal is carried out in a raster scan method with a cycle in a main scan direction. A time measurement circuit measures with a finer accuracy than one pixel clock with the use of pulses detected from a start position sensor and an end position sensor and from the index sensor 312.

Abstract: PURPOSE:To make it possible to enter a washing place with ease by installing a heat conduction board with large heat conductivity into the floor of the washing place from a spot near the outer periphery of a bath tub, and what is more, installing an insulation material with small conductivity to the outer periphery of the heat conduction board. CONSTITUTION:When hot water is Let in a bath tub 1, the heat of this hot water is transferred to a heat conduction board 3 installed to a spot near the outer periphery of the bath tub 1 by way of the wall of the bath tub 1. Since the heat conduction board 3 provides large conductivity, the heat transferred to the heat conduction board 3 near the outer periphery of the bath tub 1 is transferred to the whole heat conduction board 3. Therefore, the heat is transferred to the internal part of a floor of a washing place 2 and the heat conduction board 3 as well so that the floor of the washing place 2 may be spontaneously heated with the heat. Furthermore, an insulation board 4 is installed on the outer periphery of the heat conduction board 3, the heat transferred to the heat conduct ion board 3 can not be readily transferred to other areas, which prevents the hot water in the bath tub 3 from being cooled to a lower temperature than required. The washing peace 2 is more accessible so that people may enter a bathroom A with out anxiety.
