Title: Production of water absorbable composite
Inventor: OHIRA KATSUJI
IPC: D06M101/16
Filed: 1987-12-10
Abstract: PURPOSE: To produce an excellent water absorbent composite having a high mechanical strength by fusing a water-soluble resin powder to the other surface of a low-melting layer such as a tapelike laminate comprising a high-melting and a low-melting synthetic resin layers and then carrying out a cross-linking treatment of the water-soluble resin. CONSTITUTION: A tapelike laminate comprising a layer 2 of, e.g. a high-melting synthetic resin (e.g. a crystalline polypropylene) and a layer 3 of a low-melting synthetic resin (e.g. a polyolefin graft modified with an unsaturated carboxylic acid) and exposing the low-melting layer to the surface e.g. laminated three layers of the low-melting/high-melting/low-melting layers or an opened yarn or a composite fiber material prepared by splitting the laminate is prepared and heated at a temperature in the vicinity of the melting point of the low- melting resin to fuse a water-soluble resin fine powder (e.g. polyacrylic acid and its copolymer) to the outer surface of the low-melting layer exposed to the surface with an electrostatic charge coating machine.  The water-soluble resin is subsequently subjected to a cross-linking reaction with a cross-linking agent (e.g. sorbitol polyglycidyl ether) to afford a water absorbent composite having high water absorbing performances.

Title: Semiconductor device and its testing method
Inventor: WADA TAKASHI
IPC: H01L21/66
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To improve testing efficiency by reducing the testing time of a semiconductor device by a built-in scan chain. SOLUTION: A cell for constituting a scan chain is classified into a group of input cells 5 and a group of output cells 6 and the input cells 5 or the output cells 6 which belong to each group within the group are connected in series. The number of bits of a data S1 inputted to a scan in terminal 3 is determined by the number of input cells (m) regardless of the number of output cells (n) and hence can be compressed from a conventional (m+n).2<n> bits to m.2<n> bits, thus reducing test time. Also, by providing switch terminals 7-16 for switching the connection order of a group of input cells 5 and a group of output cells 6, other semiconductor devices with an output signal T0 as an input signal can also be efficiently tested as well as one semiconductor device.

Title: Catalyst for purification of exhaust gas
Inventor: ISHIBASHI KAZUNOBU
IPC: B01D53/94
Filed: 1990-11-19
Abstract: PURPOSE:To obtain a catalyst for purification of exhaust gas enabling efficient removal of even NOx on the lean side of gas by forming a coating layer of zeolite powder whose surface has been freed of Al on a refractory carrier, and carrying Pt on the coating layer. CONSTITUTION:A slurry is prepd. from zeolite freed of Al, a refractory carrier is wash-coated with the slurry and fired and Pt is deposited by ion exchange to produce a catalyst for purification of exhaust gas. The ion exchange may be carried out as usual by immersion in an aq. soln. of platinum ammine chloride or platinum ammine hydroxide. Zeolite particles are freed of Al by boiling in hydrochloric acid, hydrothermal treatment by heating in a steam-rich atmosphere or other method. In this case, Al is slowly released from the surfaces of the zeolite particles. Complete removal of Al must be avoided because the activity of the resulting catalyst is lowered.

Further, the air suction ports 9 are deviated from the air outlet ports 10 and, therefore, the hot air, blown out through the outlet ports 10, may not be sucked into the air suction ports 9 directly while the amount of hot air flowing the surface of a substance 2a to be heated can be reduced whereby the uniform heating of the substances 2a, 2b to be heated at the upper and lower stages may be effected upon multi-stage cooking. Accordingly, multi-stage cooking can be permitted and uniform heating can be effected with a simple constitution.
