Title: Production of plated steel sheet having excellent deep drawability
Inventor: SENUMA TAKEHIDE
IPC: C21D8/04
Filed: 1988-12-16
Abstract: PURPOSE:To produce the steel sheet which is plated with an alloy having a high m. p. and has excellent deep drawability and corrosion resistance without impairing the shape and surface characteristic by subjecting a steel having a specific compsn. to hot dip coating, then to cold rolling and annealing. CONSTITUTION:The components of the hot rolled steel sheet to be a base metal are limited, by weight, to contain <=0.05% C, <=0.01% N, and either or both of Ti and Nb so as to satisfy the relation 0.6(Ti/48+Nb/93) < (C/12+N/14) <1.2(Ti/48+Nb/93) and the balance Fe and unavoidable impurities. This steel is rolled at >=50% total draft in the temp. region of the Ar3 point or below and is then passed in an alloy bath which is formed of the alloy having >=750 deg.C m. p and is kept at the m. p. of the alloy +10 deg. or above and <=1100 deg.C by which the steel is hot dip coated. This steel is then cold rolled and annealed. As a result, the uniform plating of the plating alloy having the high m. p., for exam ple, copper alloy, on the steel sheet is possible and this steel sheet is utilizable as the stock for the high-grade surface treated steel sheet.

Title: Position detecting device
Inventor: IMAMURA TAKUMI
IPC: B23Q17/00
Filed: 1998-11-09
Abstract: PROBLEM TO BE SOLVED: To continuously connect a plurality of devices without using a tie bolt by forming passage blocks of the metal, and connecting these passage blocks to each other through a joiner. SOLUTION: When bolts 33 are fastened and joiners 29, 30 receive the force for coming close to each other, projecting pieces 25, 26 are strongly pushed into a tapered groove 32 of the joiner 29, 30 in relation to each other. Bonding force of side surfaces 23, 24 of a passage block B to each other is increased by fastening the joiners 29, 30 with the bolts 33 because the angle of taper of the tapered groove 32 is formed smaller than the angle of taper of tapered surfaces 25a, 26a of the projecting pieces 25, 26. When the side surfaces 23, 24 of the passage block B are made to abut on each other, a seal member 27 provided in one side surface 23 is crushed by the fastening margin so as to seal an opening part of a supply port.

Title: Image reader
Inventor: TAKANO YOSHIAKI
IPC: G03G21/00
Filed: 1991-11-06
Abstract: PURPOSE:To improve scanning ability by allowing a copying operation to be performed even when an original cover is opened, when the newest size estimation data in the past two times indicate the same size. CONSTITUTION:In the midst of closing the original cover 205, the size of an original on an original platen glass 16 is detected when the cover is at an angle of prescribed degrees. The size is set as control size data. This size data is stored as the size estimation data. When the original cover 205 is then opened once and closed without being opened more than the prescribed degrees of angle, the size of the original is not redetected. At this time, when the sizes indicated by the newest size estimation data in the past two times are the same, the probability that the original size is not altered is high, therefore, the previous size data (that is, the newest size estimation data) is set as the control size data.
