Title: Method for decreasing inclusion of molten steel in ladle
Inventor: KAJIMOTO TSUTOMU
IPC: B22D1/00
Filed: 1984-05-21
Abstract: PURPOSE:To decrease considerably large-sized inclusions by inserting a lance for blowing a stirring gas into the molten steel in a ladle and moving circularly the gas blow port thereof at a specific radius of rotation while rotating the lance at a specific circumferential speed. CONSTITUTION:A top blowing lance 3 is inserted into the molten steel 2 stored in the ladle 1 from above the ladle and while gaseous argon 6 is blown therefrom, the lance is rotated by a lance driving device 4 contg. rotating and swiveling mechanisms; at the same time the top end of the lance is circularly moved. The gas blow port at the bottom end of the lance is circularly moved at the radius of rotation of 1/4-3/4 the radius of the ladle while the lance 3 is rotated at a high speed of >=30m/min circumferential speed. The large-sized inclusions are thus considerably decreased and a high effect is obtd. in the production of a clean steel.

Title: Hand-free telephone
Inventor: KINEKAWA YASUKAZU
IPC: H04M1/62
Filed: 1988-04-25
Abstract: PURPOSE:To prevent the generation of hawling even when microphones and a speaker are arranged on the same plane by adjusting respective sound signals inputted through two microphones by a delay circuit and an amplification adjusting circuit and canceling the signals by a differential amplifier circuit. CONSTITUTION:Respective sound signals inputted from the speaker SP through the 1st and 2nd microphones MC1, MC2 are processed by the time delay circuit 2 and the amplification adjusting circuit 4 so that the phases and levels of both the signals almost coincide with each other. The outputs of the circuits 2, 4 are inputted to the differential amplifier circuit 5 and canceled. Thereby, the generation of howling can be prevented even when the speaker and the microphones are arranged on the same face.

Abstract: PURPOSE: To melt and join the joint of steel pipes while oxidation of the joint is being prevented so that the joining strength may be improved, by covering the inner and outer surfaces of the joining section with seal covers and by supplying a non-oxidizing fluid into the space formed by the covers.  
     CONSTITUTION: A flat steel plate is gradually bent while it is being transferred along the direction of arrow, and the joint of the steel pipe is melted and joined in a melting and joining zone 15 by high frequency induction heating apparatus fixed to a location opposing to seal covers 1 and 2. In this case, since a non-oxidizing gas is being supplied into the space formed by seal covers 1 and 2 surrounding the melting and joining zone 15, the melting and joining is performed in an atmosphere of the non-oxidizing gas, and, therefore, the melting and joining is performed while oxidation of the joint is being prevented. Weld sputterings are discharged through a clearance with the water spouted from a water supply nozzle. Beads formed on the inner surface and on the outer surface are removed by cutters 23 and 25, respectively.

Title: Laminating method for photosensitive printing plate
Inventor: KOBAYAKAWA TAKESHI
IPC: G03C3/00
Filed: 1979-08-15
Abstract: PURPOSE: To reduce charge remaining time and to prevent an operator from undergoing an electric shock, by using a paperbase with a plastic film coated on one side of the paper in laminating a photosensitive printing plate having a photosensitive layer on a metallic support.  
     CONSTITUTION: A paperbase having plastic coated layer (b) on one side of paperbase (a) is used. As its raw material, not only natural fiber, such as wood pulp or flax, but also synthetic pulp, synthetic fiber, or regenerated cellulose can be mixed. As a plastic film polyethylene is most suibable. It is more effective to enhance performance for protecting a photosensitive layer and cuttability to laminate photosensitive printing plate (c) and layer (b) in close contact with each other. In contacting them by charging them, the charge remaining time is shorter in one side coating B than in both side coating A, permitting an electrical shock to an operator to be prevented by use of B.

Title: Method for confirming multiple address communication response
Inventor: MARUYAMA HISAYUKI
IPC: H04L12/40
Filed: 1988-04-28
Abstract: PURPOSE:To confirm whether or not information arrive at all stations by returning an alarm signal with a receiving station when an error occurs at a multiple address frame, returning a response confirming frame with a transmitting station when at least one of receiving stations receives normally and investigating the presence and absence of the returning frame with the transmitting station. CONSTITUTION:One of plural stations 111-115 connected to a transmission line sends a multiple address as a transmitting station, other station becomes a receiving station, and then, the receiving station, when the error of the multiple address frame receiving is detected, sends an alarm signal and sends a response confirming signal when one of receiving stations normally receives the multiple address frame. The transmitting station does not receive the alarm signal, and it is judged that the multiple address frame is normally received by all receiving stations only when the response confirming signal is received. Thus, it can be confirmed whether or not the information is correctly communicated.

Title: Solid-state image pickup device
Inventor: TSUTSUI TAKEO
IPC: G03B17/02
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To miniaturize a solid-state image pickup device by constituting the device so that a solid-state image pickup element may be included in the rearmost lens of a lens group constituting an image pickup lens. SOLUTION: In the ordinary image pickup lens consisting of a front lens group and a rear lens group, the rearmost lens of the rear lens group is extended and the solid-state image pickup element, for example, a CCD solid- state image pickup element is enclosed in the rearmost lens. By enclosing the image pickup element in the lens, an image focal distance is the refractive index ns '-fold of that of the substance (generally, glass) of a spherical lens and ns ' is ordinarily >=1 if an object surface focal distance is the same as the case that a thin lens is used. Therefore, if the image focal distance is made the same as the case that the thin lens is used, the object focal distance gets short and the lens is miniaturized.  When the refractive index ns ' of the spherical lens to be used is made small, the object focal distance gets long, the degree of freedom in designing a wide lens is increased, and performance is improved.
