Title: Air ventilation unit
Inventor: SANADA YUKIO
IPC: E04F15/18
Filed: 1993-09-21
Abstract: PURPOSE:To obtain an air ventilation unit which has a simple construction and prevents the temperature distribution in a room equipped with a floor air outlet type air conditioner from becoming uneven. CONSTITUTION:A ceiling is build by combining air ventilation units 20. The air ventilation unit 20 has a top panel 22 that faces the inside of a room and has air vent holes 22a. A liftable plate 22a is provided parallel with the outdoor side of the top panel 22 and the distance between the liftable plate 22a and the top panel 22 is variable. The liftable panel 24 has air vent holes 24a that are arranged at positions horizontally slipping a little out of the places of the opposite air holes 22a of the top panel 22. Lifting members 26 using shape memory alloy are arranged between the top panel 22 and the liftable panel 24. The lifting member 26 is flat in shape as shown in the figure (a) when the room temperature is low, so that the ventilation rate is low as the liftable panel 24 cones close to the top panel 22. On the other hand, when the room temperature is high, it turns into a form having an arc-shaped cross section as shown in the figure (b), so that the ventilation rate becomes high as the liftable panel 24 comes away from the top panel 22.

Title: Semiconductor acceleration detection device
Inventor: IMAMURA MASAYUKI
IPC: G01P15/12
Filed: 1992-09-03
Abstract: PURPOSE:To eliminate the influence of bubbles on a detecting beam so as to enhance detection accuracy by collecting and holding the bubbles existing in a package in the dent being formed in an upper lid. CONSTITUTION:When acceleration is applied, an acceleration detecting beam 1 is warped and its stress is concentrated on a diaphragm 2. The resistance value of a gauge taking the form of a bridge circuit provided on the opposite surface of the diaphragm 2 is varied by the stress, and an electric balance is lost so that a potential difference is caused. An electric signal corresponding to the potential difference is processed so as to detect the acceleration. In that case, bubbles 10 mixed in oil 9 are moved upwards by buoyancy and are collected and held in the dent 11 of a lid 4 and thereby. prevented from obstructing movement of the acceleration detecting beam 1. Natural convection is caused between the dent 11 and the other portions by the temperature change of the oil 9 and then the bubbles 10 remaining near the detecting beam 1 are gradually moved into the dent 11 and settled there. The influence of the bubbles 10 on the detecting beam is thus eliminated so that detection accuracy can be enhanced.

Title: Method for purifying polyarylene sulfide polymer
Inventor: DEEBUITSUDO ANDORIYUU SOURUZU
IPC: C08G75/06
Filed: 1993-10-18
Abstract: A method is provided for selectively extracting the lower molecular weight fraction of a poly(arylene sulfide) polymer by contacting the polymer with a polar organic compound and a promoter compound to form a less dense polymer-lean liquid phase and a more dense polymer-rich liquid phase, separating the polymer-lean liquid phase from the polymer-rich liquid phase, and recovering the polymer from the polymer-rich phase. Alternatively, either of the phases can be isolated and polar organic compound and optionally promoter can be added to form two new phases, followed by isolation of the new polymer-rich phase. This process can be repeated as often as desired or practicable in order to recover polymer having a desired molecular weight and/or molecular weight distribution. <IMAGE>
