Title: Formation of metal coating layer
Inventor: WATANABE YASUO
IPC: C21D1/42
Filed: 1998-01-21
Abstract: PROBLEM TO BE SOLVED: To prevent recesses on the surface caused by the application of excessive electromagnetic stirring force on the molten zone at the time of remelting a primary coating layer formed on the surface of a base metal by thermal spraying or the like by induction heating. SOLUTION: At the time of subjecting a primary coating layer 11 on the surface of a base metal 10 to induction heating by an inductor 12, the penetrating depth δ of induced current is regulated to >=1.5 times the thickness (d) of the primary coating layer 11, by which the degree in which the induced current density reduces as it is deepen from the surface is made gentle, thus, the induced current density I0 in the surface of the primary coating layer is made low, and electromagnetic stirring force operating on the molten metal is made small to block the excessive flow of the molten metal, so that the generation of defects such as recesses on the surface can be prevented.

Title: Method of assembling panel with mask and funnel
Inventor: ATOBE TAKASHI
IPC: H01J9/26
Filed: 1987-02-06
Abstract: PURPOSE:To improve assembly performance of a color picture tube for making it possible to shorten the time of regulating conversion and high-resolution corresponding by using mask reference patterns to be the reference at the time of exposure. CONSTITUTION:There is a gap between mask reference patterns 3a, 3b, which are the reference at the time of exposure and also the marks of the mask centers, and an external form of a panel but the center of the mask reference patterns 3a and 3b is adjusted to the center of a funnel 1 to assemble a panel with the mask and the funnel 1. Accordingly, a gap between the center of an electron gun to be sealed to the center of the funnel 1 and the mask center is suppressed to the utmost in the later electron gun sealing process. That is, when the electron gun is sealed while recognizing the mask reference patterns 3a and 3b and correcting a position in the theta-direction so as to correspond to a tunnel of the electron gun cup, a gap of the electron gun in the directions of X, Y, theta alike to the mask center can be prevented. Thereby, a convergence characteristic can be improved while being able to match a high-resolution color picture tube.

Abstract: PURPOSE:To solve such troubles as mis-writing on the front of an envelope or enclosing an unrelated card in the envelope. CONSTITUTION:An envelope with a card consists of an envelope 2 that is made by folding a sheet of paper in two to form a front sheet 2a and a back sheet and sealing it along the two parallel sides of the front sheet 2a and the back sheet of the envelope 2 with the remaining one left open, and a peelable card 3 attached on the front sheet 2a of the envelope 2.

Abstract: PURPOSE: To prepare a chloroprene copolymer useful as an oil-resistant rubber, without emitting irritative odor under improved working conditions on the standpoint of environmental sanitation, by drying the copolymer of chloroprene and an  unsaturated nitrile etc. with an expansion-type dryer.  
     CONSTITUTION: The water-containing coagulum 8 of a copolymer of chloroprene and an unsaturated nitrile (e.g. acrylonitrile) or monomers copolymerizable therewith (e.g. styrene) is continuously fed from the inlet 1 of an expansion-type dryer. The coagulum is transferred to the compression zone 2 by rotating the screw 5. A considerable amount of water 9 is squeezed out by compression action and discharged from the outlet 3 through the screen 7. The coagulum is transferred forward and injected through the narrow nozzle of the die 4 under high temperature and high pressure caused by the frictional heat to change the residual water to steam 10 in a moment, and consequently to give the dried polymer 11.

Title: Trunk reservation system
Inventor: SUGINO MASAKAZU
IPC: H04Q3/58
Filed: 1980-02-29
Abstract: PURPOSE:To prevent an urgent call, calls from important persons, and so on from being impeded, by making it possible to acquire a specific trunk in the same trunk group only from a specific extension subscriber when the traffic intensity becomes high in the PBX. CONSTITUTION:When all central office trunks NO.0COT-NO.NCOT become busy, the HTF relay is operated. In this case, since NO.0COT is designated as a reserved trunk, the htf' break contact and the trunk selecting circuit of NO.0COT are cut off by the operation of the HTF relay. When a specific extension subscriber dials the trunk line originating number under this state, the CLS relay and the OG relay are operated to select NO.0COT. Consequently, after the operation of the HTF relay, NO.0COT is reserved only for the specific extension subscriber immediately after the service of NO.0COT.

Title: Image recording method
Inventor: OKUZAWA TSUGIO
IPC: G03D15/04
Filed: 1988-02-08
Abstract: PURPOSE:To easily operate an image recorder again after jamming is released when abnormality occurs outside a feeding part by judging whether a recording material being fed is long enough to be carried, cutting the recording material into the shortest length which can be carried and stopping operation. CONSTITUTION:When jamming occurs outside an exposing part, a photosensitive material detects whether it is currently exposed or not at the time when jamming occurs. If so, it is detected whether the photosensitive material S is cut or not. When it isn't cut yet, it is detected whether the photosensitive material is long enough to be carried or not. When the photosensitive material S is long enough to be carried, the photosensitive material S is cut at the same time when detecting is performed so as to stop the operation of the image recorder. When the photosensitive material S isn't long enough to be carried, a motor driving circuit is supplied with an operation signal. While the photosensitive material S is fed, the number of pulses is counted in response to the shortest length of the photosensitive material S which can be carried. After that, supply of the operation signal to the motor driving circuit is stopped and the photosensitive material S is cut so as to stop the operation of the image recorder. Thus, jam processing and operation start after jam processing are facilitated.

Title: Signal processor
Inventor: MATSUMOTO TAKAHIRO
IPC: G01S13/44
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To make a target detectable distinguishably from the background by processing signals by correlating the signals with a reference signal indicating the radio wave reflecting intensity distribution of the target. SOLUTION: An antenna 1 receives reflected waves of a transmitted wave radiated upon a target reflected by the target and background in two directivity patterns and outputs a sum signal Σ and a difference signal Δ to a receiver 2. A signal processor 3b converts Σ video signals and Δ video signals outputted from the receiver 2 into digital signals at every range bin by means of an A/D-converting section 4 and outputs sequences of numbers Σ and Δ. A reference storing section 8a stores a reference signal which is the sequence of numbers representing the radio wave reflecting intensity distribution of the target and a correlating section 9a correlates the sequence of numbers Σwith the reference signal and outputs a correlative value.  A target detecting section 5b detects the target from the correlative value and outputs the range bin number of the target. A distance detecting section 6 outputs the distance to the target from the range bin number and an angle error detecting section 7b inputs the sequences of numbers Σ, Δ, etc., and outputs an angle error.
