Abstract: This invention relates to a vibration-type gyro apparatus for measuring an angular velocity using the Coriolis force exerted on a tuning fork. The tuning fork has two vibrational members symmetric about a Z axis. The two vibrational members vibrate along Z axis and are displaced along a Y axis by the Coriolis force. Each of the two vibrational members includes a cantilevered tabular member arranged along an XZ plane and has a shape symmetric about the center axis thereof. Electrode sections are formed on the two sides of the vibrational members, and electrodes are formed in the internal space of a casing at positions corresponding to the electrode sections. The electrodes are arranged by being deviated outward or inward of the center axis of the vibration members with respect to the electrode sections. Each of the electrodes is supplied with a displacement detection AC voltage and a control voltage from a detection and drive circuit.

Abstract: Individual sheets of paper currency or bills are conveyed in line in a path from a receiving inlet slot through a verification station and outputting verified currency through a storage slot. The verification station senses the value and authenticity of the currency and converts the value into a signal and thereafter moves the paper currency to the storage station where they are securely stacked one on top of the other.

Abstract: A stack of light-deflecting elements are installed in a window. Each deflecting element has a solar ray inlet, a curved middle section and an end comprising a ray outlet into the room. Each element is rectilinear at the outlet end so that rays are dispersed and emerge from the light-deflecting elements in prisms of rays, the bottom edge of which is horizontal. The solar rays entering the light-deflecting elements are subjected to multiple total internal reflections at a different angle. The angle of the normal line of the deflector elements to the horizontal is selected so that the largest possible amount of sunlight can be captured and conveyed into the room to illuminate the room with a uniform, diffuse distribution.

A fluid throttling arrangement is provided to decelerate the piston towards the ends of its stroke. The fluid actuator may also be associated with an engine valve assembly. A fluid actuated engine piston assembly is also described.

Abstract: A method for the qualitative determination of the visible levels of glycol and/or formaldehyde at significant concentrations greater than 10 ppm (10 ppm-10,000 ppm range) in a water sample, in which the sample is treated first with periodic acid, then with iodide-thiosulfate and finally with acetyl acetone to yield a yellow color without the benefit of heat. This yellow color is visible to the naked eye and proportional to the amount of contaminants ethylene glycol, propylene glycol and/or formaldehyde present in the original water sample.

Abstract: A combined picture frame and mailer is formed of a single piece of reinforced paper folded along a horizontal axis into two substantially equal halves forming front and back panels. The front panel has a central cutout providing a window behind which the picture is placed and which is covered by a transparent sheet of cellophane. The back panel is provided with flaps about its remaining peripheral edges which fold over the corresponding edges of the front panel, and which are sealed to form a closed thin envelope. The back panel is also provided with fold out legs permitting the frame to stand alone on a flat surface such as a table as well as space in which the user may write a message as on a postcard.

Abstract: A garment is constructed by forming panels of first and second matching layers of two new and useful polyester fabrics sewn together along their edges. The composite panels are sewn together in such a fashion as to create a garment that will provide an effective barrier to dirt and dust particles.

Abstract: An acceleration detection gyro apparatus is of the electrostatic supporting type. This gyro apparatus call be made inexpensive, long in life, excellent in durability and can be applied to a wide variety of fields. A gyro rotor (20) is supported relative to a gyro case (21) by an electrostatic supporting force in a non-contact fashion and rotated about the spin axis along the Z axis by a rotor driving system. The gyro rotor (20) is disk-shaped and constructed by forming metal thin film electrodes on both surfaces of a plate member made of preferably an insulating material. The gyro apparatus includes a slave control system for slaving a displacement of the gyro rotor (20) relative to the gyro case (21) in the Z-axis direction (spin axis direction) and a central position control system for slaving a displacement of the gyro rotor (20) in the X-axis and Y-axon directions.

Abstract: A fiber optic gyro can overcome the defects encountered with conventional fiber optic gyros of phase-modulation method, closed-loop system with serrodyne modulation and digital modulation. A reference phase difference .DELTA..beta. and a ramp phase difference .sigma. are generated in an interference light intensity signal I by use of a triangular waveform, i.e., delta serrodyne waveform signal. The reference phase difference .DELTA..beta. is changed to constant values .DELTA..beta..sub.A and .DELTA..beta..sub.B whose absolute values are the same and whose signs are different at every times T.sub.A and T.sub.B. A phase x of the interference light intensity signal I becomes equal to x=.DELTA..theta.+.sigma.+.DELTA..beta.. The ramp phase difference .sigma. is controlled so as to satisfy .DELTA..theta.+.sigma.=0. Accordingly, at the stable point of the control loop, a Sagnac phase difference .DELTA..theta. is equal to the ramp phase difference .sigma..

Abstract: A wheelchair frame includes a pair of side frame assemblies, a connector connecting the two side frame assemblies, a seat, caster wheel mountings, drive wheel mountings, and a leg rest mounting. Each of the side frame assemblies have an upper frame member and a lower frame member. The upper frame member is pivotally connected at its forward end to the forward portion of the lower frame member and supported at its rearward end by a suspension support member (i.e., shock absorber) connected to the rearward end of the lower frame member. The seat is attached between the upper frame members of each side frame assembly. With this configuration, the upper frame members and the seat are free to pivot about the pivotal connection between the upper frame member and the lower frame member. In operation, the upper frame members and seat "float" up and down on the shock absorber to provide cushioning to the user.
