Title: Hairband
Inventor: ISHIWATARI HIROYUKI
IPC: A45D8/00
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To prevent the section connecting a main body and a rubber band from becoming bulky and also to prevent the rubber band from exposing itself to the outside by inserting its two ends into the tube-shaped section of the main body and fixing these ends to the tube-shaped section in such a way that the tube-shaped section will cover the rubber band when it is stretched. SOLUTION: The hairband 10 comprises a hairband main body 11 and a rubber band 13 which joins together the two end sections 12 of the hairband main body 11. The hairband main body 11 is formed by folding a piece of cloth of little elasticity in such a way that its lengthwise edges may be positioned along the imaginary central line on its backside and by sewing together the two edges. As a result, the hairband main body 11 has a tube- shaped section which is open at the two end sections 12. The rubber band 13 has its two ends 13a inserted into the tube-shaped section at the two end sections of the hairband main body 11, and is sewn on in a stretched state at positions at a specific distance each way from the ends 12a of the tube-shaped section.  This specific distance is a distance required to have the rubber band 13 covered in the tube-shaped section when the rubber band 13 is stretched for use.

Title: Majority decision fault processor
Inventor: KAWABATA HIDEJI
IPC: G06F11/18
Filed: 1989-06-30
Abstract: PURPOSE:To shorten the fault processing time by detecting a wrong processor by majority decision after receiving the output data from plural processors and at the same time detecting one of plural correct processors based on the prescribed priority. CONSTITUTION:A deciding circuit 5 decides the output of processors 1 - 3 by majority decision and interrupts the operations of these processors if the discordance is detected among the output data. Then the circuit 5 sends an identification signal 31 for the wrong processor to a reset circuit 6, a buffer circuit 8, and a write circuit 9 respectively. At the same time, one of plural correct processors is selected based on the prescribed priority and an identification signal 33 for the normal processor is sent to a read circuit 7 and the circuit 8. Furthermore a reset signal 34 is sent to the circuit 6 to reset an internal register of the corresponding wrong processor. Then a reset end signal 35 is sent to the circuit 7. Thus the contents of the wrong processor can be rewritten into those of the internal register of the correct processor at a high speed. As a result, the fault processing time covering the interruption through the restart of a process can be shortened.

Filed: 1982-10-01
Abstract: PURPOSE:To increase transfer speed of transfer base board without deteriorating stopping performance of transfer base board and without increasing a driving force thereof by moving the transfer board along the first and second guides while it is sliding on the first guide and is rotatably in contact with the second guide through a rotating body. CONSTITUTION:A guide 6 is formed on the upper surface of transfer board 3 so that it is located between a pair of guides 4. In both ends of transfer board 2, a rotating body 7 consisting of roller and a plate spring 9 having a rotating member 8 at the end are fixed opposingly. The rotating body 7 is in contact with the one side surface of the guide 6 and the rotating member 8 is pushed toward the side surface of guide 6 by the plate spring 9 so that such contactness is always maintained. Thereby, a friction coefficient for the guide 6 of transfer board 2 becomes small and a driving force required of the transfer board 2 is only 1/20 or less of the conventional one. Therefore, the stopping performance is not deteriorated and moreover the transfer rate can be increased without particularly increasing a driving force of transfer board 2.

Title: Desulfurizing method for waste gas
Inventor: NISHIZAKI SHINJI
IPC: B01D53/34
Filed: 1981-10-28
Abstract: PURPOSE:To treat waste gases with a hig desulfurization rate at relatively low temp. by treating under heating coal of low degrees of carbonization to form a desulfurizing agent and bringing said agent into contact with the waste gases. CONSTITUTION:Coal of low degrees of carbonization such as lignite and brown coal is treated under heating to decrease the volatile matter contained therein whereby a desulfurizing agent is produced. Waste gases discharged from combustion apparatus such as boilers are brought into contact with a desulfurizing tower (a) packed with such desulfurizing agent, whereby the SOX in the waste gases is adsorbed away. This desulfurizing agent is relatively low in reducing temp. and does not produce much H2 and CO which are the cause of side reaction. After the agent is regenerated in a regenerating tower (b), a reducing tower (c) and an activating tower (d), the agent is reused. Such desulfurizing agent maintains a high rate of desulfurization.
