Title: Powder impregnated with refined pyroligneous acid
Inventor: OTSUKA YUZABURO
IPC: A61L9/01
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To enable use for deodorization by a method wherein sticky tar in pyroligneous acid is treated by papaya to lessen the degree of tacky adhesion and a powder is impregnated with the liquid to allow processing thereof in a form of powder without losing deodorizing effect of the pyroligneous acid. SOLUTION: Generally speaking, individual pyroligneous acid is uneven in pH. The pH of the liquid is adjusted to 2.6-2.7 and papaya which is previously sliced with a thickness of 5-10 mm and a length of 3-4 cm cleared of the stone thereof is put into 2-3 kg/3L of a raw pyroligneous acid material to be kept immersed for about 24 hour. Then, the papaya is taken out. The solution obtained is distilled by an evaporator at a low temperature under a reduced pressure according to specified conditions. At this point, 10-15% of initially distilled solution containing large amounts of phenol, formaldehyde and the like is removed and the solution left is processed to make a CFK refined pyroligneous acid solution. Thus, a poisonless pyroligneous acid solution can be produced with the lessened degree of tacky adhesion of the tar.  The solution is mixed into dextrine and water is removed by about 30% to obtain a dry powder of pyroligneous acid.

Title: Image reading apparatus
Inventor: KAWAI TATSUTO
IPC: H01L27/146
Filed: 1986-10-07
Abstract: PURPOSE:To secure sufficient image reading performance, by inputting illumina tion light through a part, which is closer to a switch part viewed from a posi tion to be read, directing the component of the light reflected from the position to be read on an original toward the direction that is distant from the switch part, and reducing the amount of light reaching the switch part. CONSTITUTION:A light source 230 is arranged on the side of a switch part 213 viewed from a position to be lighted on the surface of an original. There fore, the position to be lighted on the surface of the original P is distant from the switch part 213. The component of the light, which undergoes mirror reflec tion at the interface of a protective layer 229 of the light and the component of the light, which undergoes mirror reflection at the surface of the original P, are directed toward the direction distant from the switch part 213. Therefore almost no luminous flux or a very small amount of luminous flux propagates in the protective layer 229 and reaches the switch part 213. Thus, a special member for blocking the input of the light into the switching part is not required. The incident light into the switch part 213 is decreased with a simple constitution, and stability in image reading can be secured.

Title: Method for cutting semiconductor wafer
Inventor: KOTANI MICHIO
IPC: H01L21/301
Filed: 1990-09-06
Abstract: PURPOSE:To prevent a soldering material from moving to the surface side of a device by cutting a wafer in such a way that the cut face of the wafer on the surface or rear side of a semiconductor chip can become wider in a wedge- or staircase-like shape toward the opposite surface side and the side line of the cut section can become longer. CONSTITUTION:Cutting of a semiconductor substrate 1 is performed from the lower surface side opposite to the upper surface side where functional element sections are mounted with a wedge-shaped blade. Since this cut face section 4 becomes wider from the upper surface of the substrate l where devices l are mounted toward the lower surface to which a semiconductor chip is soldered, the side line becomes longer and a clearance is formed. Therefore, when a cut-off chip is soldered to a package 7 with a soldering material 6, the soldering material 6 can be prevented from moving to the devices side l. As a result, the semiconductor chip assembling yield can be increased.
