Title: Straightening method for high melting metal and alloy wire thereof
Inventor: SHIGA NAOJI
IPC: B21F9/00
Filed: 1985-12-25
Abstract: PURPOSE:To improve a slipping condition and to suppress disconnection during working by subjecting a high melting metallic wire coated with a lubricating agent on the surface to a straightening treatment by stepped pulleys while heating the wire in the atm. CONSTITUTION:The high melting metallic wire or the like 1 on which the lubricating agent in drawing remains is conveyed from a spool 2 to the stepped pulleys 3. The wire is successively passed on the small-diameter pulley and large-diameter pulley of the stepped pulleys by a guide pulley 4 and is heated in the atm. in a heating stage 5. The wire is then straightened and is taken up on a spool 10. The ratio between the diameters of the two pulleys is specified to about 1.0:1.007-1.0:1.012 and the heating is executed at about 600-900 deg.C. The wire is treated by a heating stage 6 and an electrolyzing device 8 respectively prior to taking up according to need. The slip of the sliding surfaces of the high melting metallic wire or the like 1 with the pulleys 3 is thereby improved and the wear on the surface of the pulleys 3 is substantially eliminated; in addition, the disconnection during working is extremely minimized and the variance in linearity is lessened.

Title: Image processor
Inventor: MATSUURA ATSUKA
IPC: H04N1/41
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To realize both a high compression rate and excellent image quality with an inexpensive configuration automatically without imposing load onto the user. SOLUTION: Image data are divided into blocks for each of 2×2 pixels (a, b, c, d). A wavelet conversion section 402 converts each block into one low frequency component (LL) and three high frequency components (LH, HL, HH). An area discrimination section 403 uses characteristics of coefficients in the case of applying wavelet conversion to a binary area and a natural gradation area, a selection section 404 selects picture element values (a-d) not subject to wavelet conversion by the wavelet conversion section 302 for blocks of 'binary area edge' based on the discrimination result of an area discrimination section 303 and selects the coefficients (LH, HL, HH) subject to wavelet conversion in other blocks. A conversion circuit 405 assigns a sign to data selected by the selection section 404 and deletes low-order 3 bits.

Title: Live mast shouldering preventing device
Inventor: MORI HIROBUMI
IPC: B66C15/00
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To prevent such a possibility that a live mast is pulled up, insomuch that the live mast has been shouldered instead in consequence at a time when this mast is raised up for attaching the bottom boom to a body. SOLUTION: When a pulling-up angle θ of a live mast 13 is reached to an upper limit pulling angle 60 deg., an actuator 23a of a first limit switch 23 works, therefore the energization of an electric current to a derricking drum is interrupted. Accordingly, any winding of a derricking wire rope is stopped, and a pull-up motion of the live mast comes to a stop. In addition, when a bottom boom is installed in a turning frame 21, an actuator 24a of a second limit switch 24 works, whereby the current energization to the derricking drum is reopened irrespective of the pulling angle θof the live mast 13. Therefore, the derricking wire rope is wound up irrespective of the pulling angle θ of the live mast 13.

Title: Bipolar type semiconductor device
Inventor: ITO TAKASHI
IPC: H01L21/331
Filed: 1987-11-20
Abstract: PURPOSE:To speed up a device by a method wherein an emitter is formed of a metal silicide whose energy band gap is wider than that of the semiconductor material constituting a base. CONSTITUTION:A p-type base layer 11 is formed on an n-type silicon collector 13 and, on the p-type base layer 11, a field insulating film 14 is selectively formed. In an opening provided in an emitter forming region built of the field insulating film 14, an emitter 12 is formed of a metal silicide. The metal silicide for the emitter 12 should be wider in energy band gap than silicon that is the material for the p-type base 11. In such a design, because holes in the base region must go over a barrier that is higher than that electrons out of the emitter are to go over, an adequately high current amplification coefficient is achieved.

Title: Method for decreasing iron loss of grain oriented silicon steel sheet
Inventor: FUKUDA BUNJIRO
IPC: C21D8/12
Filed: 1985-12-26
Abstract: PURPOSE:To considerably decrease an iron loss with good safety by radiating a plasma flame to a grain oriented silicon steel sheet having a prescribed average grain size and magnetic flux density. CONSTITUTION:The plasma flame is radiated to the grain oriented silicon steel sheet having >=3mm average secondary recrystallization grain size and >=1.85T magnetic flux density at 1,000A/m magnetization force. The plasma flame in this stage is preferably radiated linearly in the direction approximately perpendicular to the rolling direction. The angle may be inclined by about 45 deg. and the radiation may not be linear but be spot-like or curvilinear. Since the iron loss of the steel sheet is extremely low according to the above-mentioned method, the energy loss of an electrical apparatus such as transformer for the iron core of which the grain oriented silicon steel sheet is used is considerably decreased.

Abstract: PURPOSE:To expand the application range to transmission systems and to improve the maintenablity by adopting a constitution such that the f<1/2> characteristic is obtained through the cascade or parallel connection of variable amplifiers whose natural frequency is made different at the interval of nearly four times and whose gain is variable.

By using a filter having the frequency characteristic as shown in the figure and whose low frequency interruption frequency F0 corresponds to the Fm, the combined overall characteristic is as illustrated in figure and the f<1/2> characteristic is approximated. Even with a comparatively narrow variable range in the amplification factor A, the transmission line loss is made variable continuously over a wide range by increasing the value (n).
