Title: Mounting structure of armrest for automobile
Inventor: SATO HIROYUKI
IPC: B60J5/04
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To provide a mounting structure of armrest for motor vehicle capable of reducing the impact to an occupant even if an impact force is added from the side of a vehicle. SOLUTION: A trim board 2 is formed by adhering a core material, a pat and a surface skin together, and it has an opening part 22. An armrest 3 has a flange part 31, an armrest body 32 and a stepped part 4, and mounted on a mounting boss 23 on the reverse side 21 of the trim board 2. The stepped part 4 is provided around the boundary part between the flange part 31 and the armrest body 32. When an impact is added to the armrest 3 from the side of a vehicle (the left side of the drawing) in the state where a door inner panel is mounted so as to be covered with a door trim, the mounting boss is fused and ruptured, and collided to the door inner panel (arranged on the right side of the trim board) to crush and break the stepped part 4. The armrest 3 absorbs the impact stepwise.

Title: Blade cleaning device
Inventor: SUGIYAMA TAKASHI
IPC: G03G21/00
Filed: 1982-05-24
Abstract: PURPOSE:To absorb the expansion and strain of a blade due to a temperature rise at the circumference of a cleaning device, and to prevent the generation of an oscillation noise by forming slits at the tip part of the blade member at right angles to the shaft of an image carrier. CONSTITUTION:The slipts 10a and 10a perpendicular to the shaft of a photosensitive drum 1 are made in the blade 10 at a distance of length l1 from both ends of the blade 10, and their length are set equal to the length l2 of projection of the blade 10. The slit gap delta of the slit 10a is large enough to absorb the strain of the blade 10 due to the expansion in the shaft direction of the photosensitive drum. Consequently, the strain and expansion of the tip part of the blade 10, i.e. variation DELTAU at the center part and variation DELTAL at end parts are eliminated to realize uniform press contacting in the shaft direction of the photosensitive drum. Thus, the oscillation of the blade in case of a temperature rise is prevented.

Abstract: PURPOSE: To increase the degree of integrity of a transistor by increasing the surface area of an active area by forming protective side wall layers on side walls and the surfaces of trenches and thermally growing oxide layers upward from the bottoms of the trenches. CONSTITUTION: A substrate 10 is provided with a silicon oxide layer 12 on its upper surface and, when a silicon nitride layer is deposited on the layer 12 and patterned, a nitride film 14 having opening areas 16 and 18 is left. In addition, when the film 14 is anisotropically etched, trenches 24 and 26 are formed. When a silicon nitride layer 32 having the same shape is deposited and the flat section of the layer 32 is removed by anisotropic etching, side-wall nitride layers 34 are left on tapered edge sections 30 and side-wall nitride layers 36 are left on tapered edge sections 28.

When the layers 34 and 36 are removed, conductive surfaces are left, but the surface area between the boundaries of the beak sections 42 and 44 becomes wider. As a result, a transistor which is improved in degree of integrity is obtained.

Title: Manufacture of porous material
Inventor: KAMIJIYOU EIJI
IPC: B22F3/11
Filed: 1979-07-13
Abstract: PURPOSE: To manufacture uniform inorg, porous material having ≥90% porosity, by mixing metallic powder or ceramic powder with org. bonding material and its solvent, and with an org. foaming agent, by heating so as to cause it to foam and to evaporate the solvent and to solidify the mixture, then by sintering the solidified material.  
     CONSTITUTION: Metallic powder or ceramic powder is mixed with an org. bonding agent, then with a suitable solvent for said bonding agent to form fluid suspension. The suspension is mixed uniformly with flaky or powdery org. foaming agent and is caused to foam, at a suitable temp. thereby evaporating the solvent and solidifying the suspension. The solidified suspension is sintered at the sintering temp. for  the powder formed from the suspension while decomposing and volatilizing the org. bonding agent and org. foaming, heat-bonding adhesive. The org. foaming agent exhibits excellent dispersibility, and use of a large quantity of the org. foaming agent exerts hardly bad influence. Hence porous material having uniform pore diameter compared with that of products manufactured by conventional methods is obtained.

Title: Semiconductor substrate
Inventor: AISATO TAKASHI
IPC: H01L21/20
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of electron mobility in an InGaAs layer by gradually reducing mixed crystal ratio of a second layer formed of InGaAs from a center of a layer to a layer boundary in a semiconductor substrate with a third layer. SOLUTION: An InGaAs channel layer 16 is constituted of three layers. Mixed crystal ratio of In in an InGaAs layer 13 is 0.2, and the In mixed crystal ratio of graded layers 16a and 16b at the top and bottom of the layer 13 becomes 9 gradually as they come near a buffer layer 12 and an AlGaAs electron supply layer 14. The mixed crystal ratio of In is 0.2 because scattering called alloy scattering is generated when the ratio of In increases further and mobility of electron deteriorates, and when it is not more than that, there is no effect to introduce InGaAs. Meanwhile, in the graded layers 16a, 16b, lattice matching to upper and lower layers is an aim of introduction; therefore, mixed crystal ratio of In is not always necessary to change from 0 to 0.2 precisely and it can be a value to lead lattice matching in the neighborhood of 0 and 0.2.
