Title: Bobbin conveying device
Inventor: NAKAGAWA TAKASHI
IPC: B65H67/06
Filed: 1993-08-13
Abstract: PURPOSE:To prevent a bobbin for a target variety of thread from being fed to a unit part in the case of a lot change or the like by connecting an empty bobbin storing path, in which a bobbin for the specific variety of thread can be scored by request, to an empty bobbin convey-out path of an automatic winder. CONSTITUTION:When a lot change is carried out only in an A variety winding unit part 1, or when an actual bobbin to be supplied to an A variety actual bobbin supply station 11 is emptied, a tray moving in an empty bobbin carry-out path 7 is stopped once by a tray stopper 17. When a signal emitted from a variety discriminating sensor 18 is the signal corresponding to the A variety, a switching lever 19 is actuated, so that the empty bobbin carry-out path 7 is closed, and the tray is diverted to an empty bobbin storing path 10. On the other hand, when a signal emitted from the variety discriminating sensor 18 is the signal corresponding to the B variety, the switching lever 19 is not actuated, so that the tray goes straight ahead in the empty bobbin carry-out path 7 and enters a conveying path 15.

Title: Condensor
Inventor: WADA KIKUO
IPC: F28B1/02
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To increase a contact time between steam and a helical pipe and to improve condensation efficiency of steam by providing a steam inlet nozzle formed in such a manner that inflow steam is spirally advanced toward the other end or one end of a drum part along a space. SOLUTION: Air containing steam flowing in through a steam inlet nozzle 65 is spirally advanced along a space between a drum part 43 and a partition wall 55, i.e., a space in which a helical pipe 53 is arranged. Thus, a contact time of steam and cooling water with the helical pipe 53 through which the steam and the cooling water flow can be increased and the condensing effect of steam is increased. Water condensed on the surface of the helical pipe 53 is dropped and stored as condensate 59 at the lower part of the drum part 43. A bottom piping 57 connected to a position below the helical pipe 53 is arranged at a part to store the condensate.  Thereby, even in such a state that the storage time of the condensate 59 is increased, the temperature of the condensate 59 is held in a state that the temperature is approximately equal to the water drop temperature of the condensate and re-vaporization of steam is prevented from occurring.

Title: Control of knocking in internal-combustion engine
Inventor: ANZAI KATSUSHI
IPC: F02P5/153
Filed: 1982-12-20
Abstract: PURPOSE:To keep a knocking frequency in constant by a method wherein a time interval between the generation of knocking of this time and the same of next time is measured and the delaying amount of a correcting spark angle is increased when the time interval is shorter than a first predetermined time while it is decreased when the same is longer than the second predetermined time. CONSTITUTION:In a step 81, the time interval between the generation of knocking of this time and the same of next time is decided whether it is shorter than the first predetermined time (0.5s for example) or not. If the decision is YES, the delaying amount thetak of the correcting spark angle is increased. On the other hand, above-described time is decided whether it is longer than the second predetermined time (0.8s for example) or not. If it is YES, the delaying amount thetak of the correcting spark angle is decreased. According to this method, the frequency of the generation of the knocking may be kept in constant.
Patent JP-H0272555-A (JP)
Title: Sealed lead-acid battery
Inventor: NAKAMURA KENJI
IPC: H01M50/103
Filed: 1988-09-06
Abstract: PURPOSE:To enhance sealed reaction efficiency and discharge performance by installing a plurality of ribs on the side wall inside a container. CONSTITUTION:If ribs 2 do not exist in a container 1, oxygen gas evolved in a positive plate during overdischarge passes through a separator 4 as shown in an arrow A and reaches a negative plate 3. In this case, pores are needed in the separator 4 and the amount of an electrolyte corresponding to the pore volume is expelled. On the other hand, if ribs are installed, gas reaches the negative plate 3 through a path as shown in an arrow B. Passing through this route is easer for gas compared with pushing away the electrolyte in the separator. Since oxygen gas passing through the separator 4 is reduced compared with the case having no ribs 2, the amount of electrolyte is increased. Discharge performance and sealed reaction efficiency are improved.
