Title: Rotary head drum device
Inventor: SUGIZAKI YASUO
IPC: G11B15/61
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To secure stable tape traveling by making an air film thin between a drum and a tape without increasing tape tension. SOLUTION: A magnetic tape 1 pulled out from a tape cassette 5 is passed through a tape tension regulator 4, a tape inlet side guide 3 and a mirror face flat guide 7 and guided to a rotary head drum 2. The mirror face flat guide 7 is disposed in the middle position of a pair of tape guides 8 and 9 provided along the traveling direction of the tape 1. By a pressure-reducing phenomenon caused by sliding contact between the mirror face flat guide 7 and the magnetic tape 1, an air film between the rotary head drum 2 and the magnetic tape 1 is reduced, and the magnetic tape 1 travels as if it is sucked thereto. Thus, without increasing tape tension, the air film between the guide and the tape is made thin, and stable tape traveling is secured.

Title: Hot water feeder
Inventor: MORI KEIICHI
IPC: F24H1/00
Filed: 1981-09-09
Abstract: PURPOSE: To reduce the fuel consumption by a method wherein the heat of waste hot water after use is collected by a heat exchanger and feed water is heated by the collected heat.  
     CONSTITUTION: In case where a washed material is rinsed after it is washed by hot water stored in a water tank 2, waste hot water is discharged by opening a water cock 19. In this case, the waste water is once stored in a tank 21 of the heat exchanger 17 and is then discharged from a drain 22. As a feed water pipe 16 is introduced into the tank 21, the feed water flowing into the heat exchanger adsorbs the heat of the waste water so that the temperature of the feed water rises up. Accordingly, when the washed material is rinsed by re-feeding the hot water, the temperature of the feed water rises up and therefore, the amount of combustion of fuel gas required for obtaining the same quantity of hot water of  the same temperature can be reduced.
