Title: Twin-trunk vessel
Inventor: TANABE KAZU
IPC: B63B1/12
Filed: 1981-03-06
Abstract: PURPOSE:To improve rigidity and strength and reduce a propulsion resistance by connecting the left and the right trunks with multiple beams having an angle of incidence at submerged positions. CONSTITUTION:Individual trunks 1A, 1B are connected each other with an upper connecting member 2 and lower beams 5 provided at submerged positions near the vessel bottom so that the whole hull is built in a completely closed box- typed rahmen structure. Therefore, strength and rigidity are improved. At the same time, since the beam 5 has an wing cross section with an angle of incidence when cut in the front to rear direction of the hull, a lift proportional to a square of a navigating speed of the vessel is obtained. Accordingly, a buoyant force corresponding to the lift is obtained during navigation, the overall propulsion resistance of the vessel is reduced due to a decrease of a draught of the vessel.

Title: Image forming device
Inventor: ICHIHASHI MIKIO
IPC: G03G15/00
Filed: 1995-02-22
Abstract: PURPOSE: To prevent a curl from occurring on ejected recording paper even in the case of using a fixing roller having a small diameter by providing a 2nd pair of paper ejecting rollers having 2nd circumferential speed higher than 1st circumferential speed and 2nd pressing force smaller than 1st pressing force. CONSTITUTION: The curl formed on the recording paper 14 by the fixing roller 18 and a pressure roller 20 is corrected when the paper 14 is ejected through a pair of paper ejecting rollers 22 and 26. Namely, the circumferential speed of the driving roller 26 is lower than that of the driving roller 22 and the pressing force of a driven roller 22b is larger than that of a driven roller 26b, so that tension caused by the difference of the circumferential speed between both of them is applied to the paper 14 in a state where the slip of the trailing edge of the paper 14 is restrained because of the difference of the pressing force between both of them. Furthermore, when the tension is applied to the paper 14, the paper 14 is pressed on an intermediate roller 24. Thus, the paper 14 is warped in a direction reverse to a direction where the curl is formed, whereby the curl is corrected.

Title: Tool material for firing
Inventor: OKIYAMA TAIJI
IPC: C04B35/443
Filed: 1995-01-30
Abstract: PURPOSE: To improve reaction resistance and durability and to reduce the production cost of a tool material for firing of a soft ferrite compsn. having a spinel structure by using a material containing MgO.Al2 O3 as the main component and ZrO2 as the subcomponent. CONSTITUTION: This tool material contains 85-99.5wt.% MgO.Al2 O3 as the main component and 0.5-15wt.% ZrO2 as the sub component. Compared to a tool material comprising alumina or alumina-mullite, the obtd. material causes no irregular shrinkage in the ferrite nor such a problem that SiO2 reacts with the ferrite to damage the crystal of the ferrite and to deteriorate the characteristics of the ferrite. Since the obtd. material contains ZrO2 , it is excellent in durability and inexpensive compared with a material comprising zirconia or magnesia.  Since the obtd. material contains one or more elements of the metal elements which are present in the soft ferrite having a spinel structure, and since the material contains <=5wt.% compsn. of the same spinel structure as the ferrite, no influence of movement of the component from the ferrite to the tool material is caused, which means any pretreatment is not necessary.
