Title: Program combination controller
Inventor: KOJIMA KENJI
IPC: G06F9/445
Filed: 1989-02-10
Abstract: PURPOSE:To surely prevent the fault that is once produced due to a program bug by preparing a combination table part to previously store the combinations of faulty programs and checking these program combinations after collating them with each other. CONSTITUTION:A combination table part 2 stores previously the combinations of faulty programs. A combination checking part 3 collates the program combination stored in the part 2 with the program combination to be started to check the presence or absence of a fault. Then a check result output part 4 grants the start or the loading of a programs as long as no occurrence of a fault is decided by the part 3. Thus a combination history pattern of faulty programs is stored in the part 2 and the start or the loading of programs is granted unless the coincidence is secured with the combination history pattern. Thus it is possible to surely prevent the faults due to the combinations of programs.

Title: Production of liquid crystal display device
Inventor: SAITO YOSHIMASA
IPC: G02F1/1337
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To obtain a uniform and stable liquid crystal alignment state and a pretilt angle by first irradiating polarized UV rays to regulate the alignment direction of a liquid crystal, then rotating a transparent substrate, and irradiating the substrate with polarized UV rays to regulate the pretilt angle. SOLUTION: First, a UV-reactive liquid crystal alignment layer is formed on one or both of a pair of transparent substrate. Then the liquid crystal alignment layer on the transparent substrate parallel to the referential plane is irradiated with polarized UV rays (first irradiation). As for the light source of polarized UV rays, an electrodeless discharge type UV lamp with high output and a long life is preferably used. Then the transparent substrate on which the liquid crystal alignment layer irradiated with the polarized UV rays by the first irradiation is rotated on the referential plane. The substrate is rotated in such a manner that the alignment direction of the liquid crystal regulated by the previous process is changed into a different direction.  Then the liquid crystal alignment layer on the rotated transparent substrate is again irradiated with polarized UV rays so as to develop the pretilt angle (second irradiation).

Title: Heat treatment for metal matrix composite
Inventor: KOBAYASHI TOSHIRO
IPC: C22F1/00
Filed: 1993-02-19
Abstract: PURPOSE:To increase the strength of a metal matrix composite material performing heating to a temp. lower than the annealing room temp. of a matrix and cooling to a temp. lower than the temp. plural times. CONSTITUTION:Heat treatment is applied to a metal matrix composite material where ceramics and metal are used as reinforcement. Usually matrix metal has high coefficient of thermal expansion and reinforcement has low coefficient of thermal expansion. By the difference in the coefficient of thermal expansion crystallographical dislocation is introduced, in great numbers, into a matrix at the time of manufacture and in the cooling stage after the treatments accompanied by temp. rise, such as annealing, hardening, and artificial aging, and the yield strength of metal is increased in proportion to the square root. In order to prevent the dissipation of the dislocationz generated in the cooling stage, in a subsequent temp. rise stage, the rate of change in temp. at the time of cooling is made dissimilar to that at the time of heating. Temp. rise velocity in a heating furnace is low and cooling velocity at the time of cooling by using liquid nitrogen, liquid helium, dry ice, etc., is low. Yield stress can be improved by repeating this cooling-heating cycle plural times, e.g., 7.6%/10 times, 21.4%/100 times.

Title: Multiprocess perioxide bleaching of mechanical pulp
Inventor: PETERU TEIBURINGU
IPC: D21C9/10
Filed: 1986-02-14
Abstract: Bleaching of a mechanical pulp, such as chemimechanical pulp (CMP), chemithermomechanical pulp (CTMP), and the like, achieves high brightness. A lignocellulose mechanical pulp is subjected to two different peroxide (P) stages (12, 18), and a hydrosulfite (dithionite) (T) stage (20). A P-P-T sequence is preferred (although a P-T-P sequence also produces good results). Bleaching is typically accomplished in all stages at a consistency of between about 8-30%. Between the peroxide stages, the pulp is preferably pressed (19). Between a peroxide stage and a subsequent hydrosulfite stage the pulp is preferably pressed (19 min ), and the pH reduced to between about 5.5-6.0 when diluting with SO2 water (26). The P-P-T bleaching sequence results in pulp with unexpectedly high brightness, brightness levels of about 83% ISO, and greater, being possible.
