Title: Manufacture of electronic circuit board
Inventor: ITEMADANI EIGI
IPC: H05K3/30
Filed: 1987-10-05
Granted: 1990-07-27
Abstract: Fabrication of an electronic circuit board is carried out by forming a predetermined number of resistors having various resistance based on a circuit design stored in a memory on a nonconductive substrate and dividing the substrate into discrete resistors, then mounting the discrete resistors on a circuit board and operation characteristic. When some resistors having resistances which are not suitable to obtain a predetermined opration characteistics exist in the resistors, the resistances are corrected, and an electronic circuit board having corrected accurate electric constants is obtained. Complete electronic circuit boards are fabricated by repetition of the respective steps.

Inventor: MARKKU KOSTAMO
IPC: B01J8/38
Filed: 1988-04-20
Granted: 1991-07-13
Abstract: A fluidized bed reactor has a pair of cyclone separators which receive flue gas with entrained solids and wherein the solids are separated from the flue gas in the separators for flow into a fluidized distribution conduit. The flow of separated particles is divided into two particle streams and fluidizing air is introduced into the duct. The fluidized separated particles are then conveyed to the combustion chamber of the reactor through an upright conduit in turn connected to a downwardly inclined conduit connecting the combustion chamber with the fluidized separated particles in the duct. The downwardly inclined conduits are substantially equidistantly distributed along the lateral extent of the combustion chamber to provide even distribution of the solid separated particles with fuel mixed therein in the combustion chamber.

Abstract: PCT No. PCT/DE88/00726 Sec. 371 Date Jul. 18, 1989 Sec. 102(e) Date Jul. 18, 1989 PCT Filed Nov. 17, 1988 PCT Pub. No. WO89/04980 PCT Pub. Date Jun. 1, 1989.A main mirror for a reflecting telescope comprises plurality of individual polygonal reflecting elements (1 to 11) and positioning and adjusting elements (12) connected thereto. Prior art main mirrors of this type have a poor capacity for transmitting ponint images and for modulation and are unsuitable for use in the infrared region, because the positioning and adjustment elements, in particular the measurement sensors arranged in the region of the separating lignes between the individual polygonal reflecting elements (1 to 11) emit interfering thermal radiation. Furthermore, the polygonal reflecting elements (1 to 11) of prior art main mirrors (20) are expensive to manufacture. In order to remedy these drawbacks, the reflecting surface forms a complete circle by means of connecting reflecting elements (1 to 8) connected radially to the outer edges of the polygonal reflecting elements (9), the reflecting elements (1 to 11) are made from a lightweight preformed material, and the positioning and adjustment elements (12) are arranged below the reflecting elements (1 to 11).

Abstract: Water (3) on the outside surface (1) of a vehicle windscreen (7) causes a light beam (5) to be partially transmitted through screen (7), while a clean screen (7) provides substantially total internal reflection of beam (5). This difference is detected by light sensor (6). The presence of water is used initially to trigger the windscreen wipers and once activated, the characteristics of the signal from sensor (6) received during one wiper action are used to set the characteristics of the next wiper action, e.g. time delay, or wiper blade speed. The light beam (5) is an infra-red light.

Title: A regeneration method of collagen fiber form leather by-product
Inventor: MIN BYONG-KWON
IPC: D01C5/00
Filed: 1993-03-15
Granted: 1995-07-20
Abstract: 100 Parts of base material of a wet blue leather binded with an organic and an inorganic tanning agent and a pelt scrap and 0.1-100 parts of anionic and nonionic fatliquoring agents were mixed, swelled and decomposed to recover the collagen fiber. Thus, 500 g of dried wet blue leather of pH 3-4 and 25 g of fatliquoring compound[cationic fatliquoring agent; 10 wt.%, anionic fatliquoring agent 60 wt.%, nonionic fatliquoring agent 30 wt.%  were mixed with stirring at 50 degree C for 60 min in water. The obtained compound was decomposed for 60 min in bester to give the collagen fiber.
