Title: Air bag device for vehicle
Inventor: MINAMI YOSHIHIKO
IPC: B60R21/16
Filed: 1993-06-07
Abstract: PURPOSE:To unfold a lower part of an air bag prior to an upper part thereof to protect an occupant. CONSTITUTION:A guide member 20 is provided inside of an air bag 10, and the inside of the air bag 10 is divided into two chambers in the vertical direction to control the travelling direction of the gas to be discharged from an inflator 16 into the air bag 10 so as to be discharged downward. A lower chamber 24 of the air bag 10 is unfolded first, and next, an upper chamber 22 is unfolded. Consequently, an occupant can be protected sufficiently even in the case where the only lower part of the air bag is unfolded first. Since the necessity for unfolding the whole of the air bag at a moment is eliminated, the output of the inflator can be reduced. Even in the case where the volume of an air bag is increased, it can be expanded sufficiently large in time for protecting the occupant.

Title: Correcting device for curl of roll paper
Inventor: KATOU SHIGERU
IPC: H04N1/00
Filed: 1984-07-03
Abstract: PURPOSE:To correct uniformly curl according to variation in the diameter of roll paper by providing a roller which contacts the roll paper to control the drawing- out position of the roll paper and also curl the roll paper in the opposite direction of the curl direction and an elastic body which energizes said roller toward the roll paper. CONSTITUTION:The roller 1 which corrects the curl of the roll paper 4 is fitted to one terminal of a lever 2 and the elastic body 3 (coil spring for drawing) fitted to the other end of the lever is energized by drawing the lever 2 from a case 5 so that the roller 1 is pressed against the roll paper 4. When the roll paper 4 is thick in the beginning of use, the force for correcting the curl of the roll paper 4 with the roller 1 is small. When the roll paper is taken up and becomes thinner, the lever 2 rotates around a pin 6 as a center as shown by an arrow X by being energized by the elastic body 3 and the roller 1 shifts in position, thereby increasing the curl correcting force which curves the roll paper 4 with the roller 1.

Title: Sense amplifier
Inventor: OBAYASHI SHIGEKI
IPC: G11C11/416
Filed: 1990-05-25
Abstract: PURPOSE:To prevent an erroneous reading action in a current voltage converting means from being generated by providing a constant current source to supply a constant current based on constant voltage not being depended on the change of power source voltage. CONSTITUTION:When a voltage difference based on a data signal is obtained between pairs of I/O lines 20a and 20b, a sense amplifier activating signal, the inverse of SE, of a low level is given and a transistor Tr50 responds to the signal, the inverse of SE and is on. A constant current to flow into a constant current source 39 flows as the drain current of a Tr42. As a result, voltage between the gate and the source of the Tr42 is fixed and the drain current of the value of the real number times of the drain current of the Tr42 flows through a Tr43. Accordingly, the power source voltage dependency of the drain current of the Tr43 becomes equal to the power source voltage dependency of the constant current source 39. That is, since constant voltage Vcs1 generated by a constant voltage generating circuit 90 is not affected by the fluctuation of power source voltage, also a constant current supplied by the constant current source 39 is not affected. Accordingly, also he drain current to flow in the Tr43 is not affected by the change of a power source voltage level.

IPC: G03C1/76
Filed: 1990-05-29
Abstract: PURPOSE:To obtain a heat-resistant optical film having remarkably excellent surface smoothness and appearance by polishing and working at least one surface of an amorphous thermoplastic resin film having a glass transition point of a specific temperature or higher and limiting surface roughness. CONSTITUTION:Polyether sulfone, polyether imide, polysulfone, polyarylate and a resin obtained by blending these substances can be cited as an amorphous thermoplastic resin having a glass transition point of 180 deg.C or higher. A small quantity of a stabilizer, a lubricant and an ultraviolet absorbing agent may also be contained as an additive. Film thickness from 10mum to 500mum is desirable from the aspect of workability and flexibility. It is favorable that the surface roughness of a film is 0.1mum or less, and it is preferable that the surface roughness is further 0.05mum or less. When surface roughness is larger than 0.1mum, an irregular color is generated when the film is used for liquid-crystal display. The film can be rotated while being pressed through a polishing liquid on a polishing surface plate installed onto a surface plate in polishing.

Filed: 1990-05-29
Abstract: PURPOSE:To simplify the device by bringing the halved parts of a target disposed to face each other apart a substrate into electrical contact with each other and joining these parts, then connecting the joined part to a common power source for sputtering. CONSTITUTION:The target 12 is disposed to face the substrate 11 apart the substrate and is connected to the power source 22 for sputtering. The target 12 is formed by bringing the halved Co part 21a and Pt or Pb part 21b into electrical contact with each other and joining these parts and is connected by the common power source 22 for sputtering. The substrate 11 eventually rotates above the two parts 21a, 21b of the target 12 as a rotating plate 12 rotates. The lamination period and film thicknesses of the respective layers of the films formed on the substrate 11 are determined by the area of the Co part 21a, the area of the Pt (or Pb) part 21b and the rotating speed (pass speed) of the substrate 11. Just one power source 22 for sputtering is necessitated in this way and the sputtering device is miniaturized.
