Title: Glass substrate for information recording medium, manufacture of the same, magnetic recording medium using the substrate and manufacture of the same
Inventor: WATANABE TSUYOSHI
IPC: G11B5/64
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording medium which realizes high density recording and reproducing while maintaining stable and good magnetic characteristic by controlling surface roughness of glass substrate and fluctuation thereof to the predetermined range and equalizing the crystal grain of the lower layer and magnetic layer to be formed on the glass substrate. SOLUTION: In order to obtain an extremely high reliable magnetic recording medium which assures good magnetic characteristic and recording and reproducing characteristic and does not generate head crush, roughness Rmax of glass substrate surface is set to 15nm or less, roughness Ra to 1nm or less, square mean root roughness Rq to 1.5nm or less and moreover a ratio (Rmax/Ra) is set to 30 or less and mean crystal grain size of magnetic layer is set to 5 to 30nm. In this glass substrate, since the linear relationship exists between the film thickness of recess/projection forming layer and surface roughness, the surface roughness to obtain high CCS durability can easily be controlled.  Generation of head crush can be realized by setting the surface roughness ratio Rq/Ra of the recess/projection forming layer to prevent generation abnormal projection and surface roughness of recess/projection forming layer due to fluctuation of surface roughness of substrate to 1.5 or less.

Title: Controller for floor heating
Inventor: UMEZAWA KIYOSHI
IPC: F24D3/00
Filed: 1996-12-29
Abstract: PROBLEM TO BE SOLVED: To restrict uneven temperature on a surface and the more rise of surface temperature than needed by providing a prime mover blade made rotatable by warm water on a one warm water passage and a rotary blade for flowing warm water on the other warm water passage. SOLUTION: As a heat medium (warm water at 60 deg.C or higher or warm water at 80 deg.C) flows through a heat source machine (boiler) 1, a pump 3, a load 19 in this order, high temperature water from the boiler 1 directly enters the load 19 to bring the neighbourhood of an inlet for the load 19 to high temperature and the neighbourhood to low temperature. Herein a valve 15 of a main circuit is closed as illustrated in the figure with a sensor 17 and a control part to switch the flow of the warm water as indicated by an arrow (a second warm water passage). Hereby, a prime mover blade 9 is rotated with pump pressure, and hence a rotary blade 11 is driven with rotation force via a gear 13. As a result, the heat medium in the load 19 is circulated through a third warm water passage.  Hereby, temperature of the load 19 is made uniform to restrict uneven temperature on the surface of the load 19 and the rise of surface temperature.

Abstract: PROBLEM TO BE SOLVED: To increase the property of a Ti/Pt film as a barrier against brazing filler metal without increasing the film thickness and prevent the stripping of the film due to a sintering a process after the formation of the film by depositing, on a contact layer, a Ti layer, a Pt layer, a Ti layer, a Pt layer, and an Au layer in this order as a P electrode of a five-layer structure. SOLUTION: A SiO2 film 10 is formed on a p-GaAs cap layer (contact layer) 9 and then an electrode window 11 is formed by photolithography. As a P electrode, a Ti layer 12-a, a Pt layer 12-b, a Ti layer 12-c, a Pt layer 12-d, and an Au layer 12-e are deposited in order on the p-GaAs cap layer 9. On the side opposite to the cap layer 9, an n-GaAs substrate is formed and then an N electrode is formed under it. Thereafter, in a part where Au is eliminated, the P electrode is bonded onto a heat sink with In brazing filler metal. Since the Ti/Pt layer as a barrier layer against In brazing filler metal are deposited in double layers, the property of the Ti/Pt layer as a barrier against In brazing filler metal is increased and thereby the brazing filler metal is stopped by the barrier layer and is never diffused into the cap layer 9.
