Abstract: PROBLEM TO BE SOLVED: To form diffraction gratings of different pitches at one time, by casting a first and a second optical beam on the surface of a substrate so that a cross line between the wave fronts of the first and the second optical beam may be parallel to the surface of the substrate, and then diffracting the optical beams by means of an optical element having a slant face which is inclined in a first and a second direction. SOLUTION: Using a prism 20 having a curved face 20A which is inclined in a second direction which crosses at right angles with a first direction, a first and a second optical beam 21, 22 are incident at respective incident angles so that a cross fine X between the wave fronts of the first and the second optical beam may be extended in a first direction on a reference face 20R indicated by dotted lines on the prism 20. The figure (B) shows an optical interference pattern formed on the reference face 20R when the prism 20 is inserted into optical paths of the optical beams 21, 22.  From the optical interference pattern, it can be known that a repetitious pitch of the optical interference pattern constituted of a plurality of stripes which are extended in the first direction and are repeated in the second direction changes from a first pitch A1 to a second one A2 , in the first direction.

Title: Method for imparting data
Inventor: KUWABARA KOJI
IPC: B41M3/14
Filed: 1989-01-24
Abstract: PURPOSE:To impart excellent discrimination data without being limited by the color or pattern of cloth by imparting data using both of light emitting ink and light emission control ink. CONSTITUTION:Two kinds of light emitting ink A substantially colorless under visible light and light emission control ink B are used and data is imparted by either one of the light emitting ink and the light emission control ink and the other ink is applied to the circumferential part of said data. For example, by imparting the light emission control ink B to the circumferential part 4 of the data figure 5 imparted by the light emitting ink A, the fluorescence from a white part 2 subjected to fluorescent whitening under the irradiation with ultraviolet rays becomes weak and, therefore, noise can be reduced. By this method, the S/N ratio of the fluorescences of the data and cloth can be made sufficiently large and the discrimination of data can be performed even when there are the white part 2 and a black part 1.

Title: Heating control device for electric bath heater
Inventor: YAMANAKA KAZUICHI
IPC: F24H1/18
Filed: 1983-01-28
Abstract: PURPOSE:To enable to quickly detect the abnormal temperature rise of a heating tank under the condition that the water level in a bathtub lowers below the upper mounting hole of the bathtub by a structure wherein a temperature detector is mounted on the heating tank at a location nearly same in height as the upper mounting hole of the bathtub. CONSTITUTION:When the water level in a bathtub 16 lowers below an upper mounting hole 16b under the condition that the power supply is being put to work, the water in a heating tank 11 stagnates in the heating tank because no outflowing of the water occurs through a connecting hole 12a for outflowing and at the same time raises its temperature gradually due to the heat release of a second heating tank 13 up to high temperature. On the other hand, a temperature detector 23 is mounted on the outside back surface of the second heating tank 13 at a location nearly same in height as the upper mounting hole 16b of the bathtub 16. Because no water contact with the inner wall surface of the second heating tank 13 at said location, no water burning state is realized and abrupt temperature rise is resulted at the location and consequently the temperature detector 23 reaches a predetermined temperature and turns OFF, resulting in stopping the energizing to a heating coil 17. Because the temperature of the water in the heating tank 11 is raised at this time more slowly than the speed of temperature rise of the second heating tank 13, on which the temperature detector 23 is mounted, no heating of water and consequently no vomitting of the resultant steam through the connecting hole 12b for outflowing occurs, resulting in realizing safety.

Abstract: PURPOSE:To enhance dust collecting efficiency to a large extent, by arranging plural discharge electrodes comprising two rod like bodies with circular arc cross areas having plural serrated parts provided to both side parts thereof between parallel dust collecting electrodes in an electric dust collecting apparatus. CONSTITUTION:Between parallel dust collecting electrodes 1a, 1b of an electric dust collecting apparatus, plural discharge electrodes 10 are arranged along the flowing direction of a gas to be treated so as to be parted in an extent imparting no influence to mutual corona discharges. This discharge electrode 10 is formed by integrating two conductive rod like bodies 11a, 11b with circular arc areas having plural serrated parts 12 provided to both side surfaces thereof by a connector 13. From the serrated parts 12 of the discharge electrode 10, plural corona discharges are formed toward the dust collecting electrodes 1a, 1b in a multiplex discharge form. Therefore, thus formed charging part is dense and strong and, because dust in the gas passing  through this charging part is entirely charged, said dust is electrically collected in excellent dust collecting efficiency and the electric dust collecting apparatus excellent in capacity is obtained.

IPC: F23D3/14
Filed: 1980-02-08
Abstract: PURPOSE: To prevent a heating of a burner device by a method wherein a heat radiation member is fixed at an injection part for mixture gas.  
     CONSTITUTION: Heat radiation member 19 which is made of, for example, Steatite is fixed at the top end of the mixture gas injection cylinder 15 of the burner device. Rotation of the rotary knob 11 causes the liquefied gas to be injected from a nozzle fitting 8 through the movable member 6, mixed with air entered from the air inlet ports 16, 18 in the mixture gas injection cylinder 15, and injected at the top end of the cylinder as the mixed gas. When the mixture gas is ignited, the gas is completely burnt to form a hot blue flame, but an existence of the heat radiation member 19 may prevent the top end of the mixture gas injection cylinder 15 from being heated up to a high temperature, and the part lower than the heat radiation member 19 is always kept at a low temperature, so that entire burner device may be prevented from being heated.

Abstract: PURPOSE:To identify easily the music number set for indication of playback as well as to identify easily a music number under playback from other music numbers, by displaying in regular order the music numbers indicated for playback and having optically different displays between the number of music under playback and the numbers of other music not under playback. CONSTITUTION:A designated music number counter 102 counts the designating frequencies every time a music number is designated by a digit key switch 101. A music number memory means 103 stores successively the designated music numbers. These memory contents are successively displayed ever time a music number is designated to the means 103. While a display switch means 115 applies an optical change including a change in color, the flickering, etc. to the display of a display means 104 for designated number of music under playback by means of a signal obtained while the designated music is played. Thus the number of a designated music under playing is indicated. At the same time, the output of a playing music pointer 114 is compared with the counted value of the counter 102 through a comparing means 116. Then the generation of output is stopped when the output of the pointer 114 exceeds the counted value of the counter 102.

The metallic material 11 is melted by the arc column 10, and an anodic flame 12 for forming ultrafine metallic powder is generated and sent to a filter 6 by a circulation gas. At this time, the circulating gas is blown against the metallic material 11, the arc column 10 and the anodic flame 12 from nozzles 13 through an introducing tube part 13a to concentrate the arc column 10 upon the surface of the metallic material 11. A cooling rod 14 is inserted into the anodic flame 12 to attract the anodic flame to the circumference of the cooling rod 14. Thus the anodic flame 12 is throttled and sent upward in the vessel. By this method, the ultrafine metallic powder having optimum average particle size and particle size distribution is obtained.
