Title: Device and procedure for treating the sliding surfaces of winter sport devices
IPC: A63C11/08
Filed: 1989-01-23
Abstract: The device allows a method to be carried out to treat the sliding surfaces of winter sports devices. The latter are retained with their sliding surface towards the top. Their treatment takes place by means of a heatable plate with a porous insert which can be placed resiliently against the sliding surface and is displaceable relative to the latter in the longitudinal direction. From a trough, the insert can receive a material which can be heated at least to a pasty state. A storage device for porous sheet material dispenses said material, when required, between the sole and the sliding surface. The treatment can comprise: the removal of remains of used agent from the sliding surface, which agent is absorbed by the sheet material, and/or the pre-heating of the sliding surface, the sole sliding over the sliding surface without sheet material, and/or the application of new agent from the trough, the sheet material allowing fine distribution. In this case, the agent penetrates into microcavities of the covering and any cracks in the sliding surfaces and forms a smooth, even and elastic layer on the sliding surface.

Title: Improved device for supporting the thread guide of an automatic flat knitting machine
IPC: D04B15/56
Filed: 1989-02-28
Abstract: The device is fitted to a flat knitting machine that 
comprises a carriage 90 moving above two needle beds 70, 
and featuring anchor plates 50.  
     The device comprises slides 100 mounted upon a bar 2, 
located above the needle beds, with thread guides 60 
fixed to these slides. Each slide 100 features a track 
P3 in which two facing ledges 101a, 101b are formed that 
can be struck by an anchor plate, consequently causing 
the slide to be drawn along.  
     Two rockers 40, that pivot upon each slide, comprise two 
arms 41,42, first and second, which work in conjunction 
with a ledge 101a,101b, and a side 101c of the slide.  
     If the second arm 42 is kept alongside the side 101c, 
the anchor plate 50 is prevented from striking against 
the ledge 101a, 101b, and when the same second arm 42 is 
moved away from the side 101c, the anchor plate 50 is 
enabled to strike against the ledge 101a, 101b.

Title: Method and apparatus for performing division using a rectangular aspect ratio multiplier
IPC: G06F7/483
Filed: 1990-07-27
Abstract: A method and apparatus for performing division is described which first comprises approximating the short reciprocal of the divisor. A reciprocal bias adjustment factor is added to the approximation and the correctly biased short reciprocal is multiplied by a predetermined number of the most significant bits of the dividend and the product is truncated to generate a first quotient digit value. The multiplication takes place in a multiplier array having a rectangular aspect ratio with the long side having a number of bits at least as large as the number of bits required for the divisor. The short side of the multiplier array has a number of bits slightly greater by several guard bits than the number of bits required for a single quotient digit value, which is also determined to be the number of bits in the short reciprocal. The quotient digit value is multiplied by the full divisor and the exact product is subtracted from the dividend to yield an exact partial remainder. The described steps are repeated to serially generate quotient digit values with exact partial remainders with the preceding partial remainder taking the place of the dividend. The quotient digit values are accumulated to yield a complete quotient. The complete quotient is decremented and the remainder recalculated if the final partial remainder is negative, yielding the full precision unique quotient and non-negative remainder pair.

Title: Process for coating a packaging film with a transparent barrier coating
IPC: C25D11/26
Filed: 1990-02-02
Abstract: A process for coating a polymer sheet with a transparent 
coating having moisture and oxygen barrier properties. The 
process starts with a metal substrate (10) made of, or having 
a surface coating (11) of, a valve metal or valve metal alloy. 
The metal substrate is anodized to form an anodic film (12) of 
the valve metal on the metal substrate. The anodic film (12) 
is made readily detachable from the metal by carrying out the 
anodization step in the presence of an adhesion-reducing 
agent, e.g. a fluoride. The polymer sheet (13), usually in 
the form of a thin transparent layer, is then attached to the 
anodic film (12) and the anodic film is detached from the 
metal. The transferred anodic film (12) forms a thin dense 
oxide coating on the polymer sheet that acts as a barrier 
against oxygen and moisture transport. The invention can be 
used for making packaging sheets suitable for packaging 
foodstuffs, and the like.

Title: An optical pumping-type solid-state laser apparatus with a semiconductor laser device
IPC: H01S3/131
Filed: 1990-03-28
Abstract: Disclosed is an optical pumping-type solid-­
state laser apparatus in which a semiconductor laser 
device (11) is used as a light source for optical pumping. 
The solid-state laser apparatus includes first and 
second photodetectors (12,13). The former detects the amount 
of light emitted from the semiconductor laser device, 
and the latter detects the amount of laser light 
transmitted through a filter plate (14) which has the same 
light-absorbance characteristics as that of the solid-­
state laser. In accordance with the detected results, 
a driving circuit drives the semiconductor laser device 
to obtain a laser beam with an appropriate output level 
and a temperature regulator regulates the temperature 
of the semiconductor laser device so that the 
wavelength of the laser light to be emitted therefrom 
is accurately adjusted to be the same as that of the 
light to be efficiently absorbed by the solid-state 
laser. The laser beam with the accurately adjusted 
wavelength is used for optically pumping the solid-­
state laser.

IPC: B22F3/087
Filed: 1996-04-04
Abstract: The present invention relates to a method in which a magnetic powder is 
packed into a cavity (c) of a rubber mold (m) comprising a rubber material at 
least a part of which is a mixture of rubber and magnetic powder, and then the 
rubber mold filled with the magnetic powder are subjected to a magnetic field 
and a pressure with punches (2a , 2b), thereby compressing the powder to form 
powder compact.  
     This makes the distribution of magnetic field in the cavity of the rubber 
mold more homogeneous, and therefore, the distortion, cracking and chipping 
caused by inhomogenity of the distribution of the magnetic field are prevented, 
and the resultant powder compact becomes more near-net-shaped i.e., closer to 
the end product.
