Title: Instrument for detecting molten metal surface
Inventor: KAWAI HIROSHI
IPC: G01F23/24
Filed: 1995-02-23
Abstract: PURPOSE: To detect the arrival of molten metal surface to the position of an electrode even in the case of the existence of releasing agent by constituting a part of the wall surface of a cavity of the electrode and an electric insulating material between the electrode and a metallic mold and providing an electric resistance detecting means between the electrode and the metallic mold. CONSTITUTION: The detecting sensor 12 is constituted of an electrically conductive pin part 14 made of Fe-Ni steel and a ceramic-made insulating material 16 for insulating the metallic mold 2 and the pin part 14 from each other. The tip part of the detecting sensor 12 is arranged continuously with the wall surface 4W of the cavity 4. The detecting sensor 12 is connected electrically to the terminal of a signal output part, and the signal indicating whether the pin part 14 of the detecting sensor 12 and the metallic mold 2 are brought into electric contact with each other with the molten metal or not, is outputted.  This molten metal detecting instrument measures the electric resistance between the pin part 14 and the metallic mold 2 and can judge whether or not the molten metal surface reaches the position of the detecting sensor 12 from the variation of the resistance value even in the case of the condition of being coated with the releasing agent.

IPC: G02B1/14
Filed: 1985-02-26
Abstract: PURPOSE:To obtain the lens having the same extents of the optical property, the adhesion, and the hardness to those of the conventional film obtd. at a high temp. of >=250 deg.C by forming the film of metal oxides at a low temp. of about 60 deg.C according to a reactive ion plating of oxygen under a prescribed oxygen pressure. CONSTITUTION:The metal oxides films of Ta2O5, Al2O3, Y2O3, CeO2, ZrO2, and In2O3, are formed under the oxygen pressure of 6.0X10<-5>-1.0X10<-4>Torr. The metal oxide films of SiO2 and TiOx(X<=2) are formed under the oxygen pressure of 1.0X10<-4>-3.0X10<-4>Torr. The lack of oxygen due to the conventional vacuum deposition and the ion plating methods in the film forming method is avoided by the method as mentioned above, thereby obtaining the film having a prescribed refractive index and a good adhesive property and a improved hardness of the film. As the film forming temp. is a low temp. of 60 deg.C, the profile irregularity and the change of the refractive index due to the temp. are solved.

Filed: 1985-02-25
Abstract: PURPOSE:To obtain a multicolor image by a single process, by pressing a transfer sheet against a color developer sheet coated with color developers for developing the colors of leuco dyes, thereby transferring. CONSTITUTION:For example, where cyan, magenta and yellow microcapsules 3 are reactive to rays with wavelengths of lambda1, lambda2 and lambda3, respectively, when the transfer sheet 1 is irradiated with rays with a wavelength of lambda1, only the cyan microcapsules 3 become liable to be broken under a low pressure, while the magenta and yellow microcapsules 3 are not affected by the irradiation. Therefore, when the transfer sheet 1 is irradiated with rays according to three primary color signals from a color display or the like, the microcapsules 3 on the sheet 1 corresponding to the signals become liable to be broken under a low pressure, and when the sheet 1 is pressed against the color developer sheet 7 (which is coated with color developers for developing the colors of leuco dyes) with a low pressure for transfer, only the microcapsules 3 at the parts irradiated with the rays according to the signals are broken, and the colors are developed, whereby a multicolor image can be formed by the single process.

Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To conduct data communication between normal stations by matching a transmission speed with an optimum transmission speed in response to a state of a network. SOLUTION: In the case of revising a data transmission speed, a master station M sends a transmission speed revision command to slave stations S1-Sn. Then the master set regards slave stations not returning a transmission speed revision response within a prescribed condition to be not in existence and sends a transmission speed revision execution command only to slave stations returning the transmission speed revision command to revise the transmission speed and revises the transmission speed of itself and makes data communication only with slave stations with the transmission speed response.  Furthermore, when the slave stations returning the transmission speed revision response do not receive the transmission speed revision execution command from the master station after a prescribed time, the slave stations revise the transmission speed based on the transmission speed information included in the transmission speed revision command.

Abstract: PURPOSE: To more surely control a gate by detecting which area in the gate passes a passenger by a sensor capable of sensing a distance. CONSTITUTION: When a passenger passes a passage held between gate bodies 1A, 1B by opening flappers 4A, 4B, the existing range of the passenger in a gate area is judged by a control part 11 based upon signals outputted from sensors 9A, 10A. At the time of detecting the existence of a person in an exit area without detecting his (or her) entry for instance, gate control such as a reverse entry error is executed. Since the position of a passenger in the gate area can be detected as compared with conventional control for detecting only a passenger existing in front of a sensor, more surely gate control can be attained.
