Filed: 1992-06-09
Granted: 1993-08-31
Abstract: Abstract of the Disclosure A housing assembly for supportively housing a circuit board in fixed engagement therewithin. The housing assembly forms a support surface for receiving the circuit board at an unlocked position. Sliding translation of the circuit board is permitted upon the support surface to position the circuit board at a locked position. Translation of the circuit board causes elastic deformation of clamps which exert clamping forces responsive thereto to affix the circuit board in position at the locking position.

Abstract: A dry analytical element for the determination of serum cholinesterase (CHE) activity is disclosed. The element analyses undiluted body fluids and employs butyrylthiocholine as the substrate for CHE. Butyrylthiocholine is hydrolyzed by serum cholinesterase and liberates butyric acid and thiocholine. The thiocholine liberated then reduces ferricyanide to ferrocyanide and the rate of change is measured by reflectance densitometry.

Granted: 2000-11-07
Abstract: The present invention provides a waveguide system for a microwave oven comprising a cavity for holding food to be cooked and having a plurality of microwave feed openings formed in one wall thereof; a magnetron having an antenna and positioned between the microwave feed openings in spaced apart relation to the wall having the feed openings, to generate microwaves having a wavelength of .lambda.g; and a waveguide to cover the feed openings, support thereon the magnetron and guide the microwave through the feed openings into the cavity and having a short circuited surface which is spaced apart from the antenna by a distance of approximately .lambda.g/4 and is parallel to the antenna. With this arrangement, the microwaves generated in the magnetron produce standing waves in the waveguide, and then are emitted into the cavity through the microwave feed openings of the cavity, thereby uniformly heating a food in the cavity.

Title: Laminated bottle and pump device therefor
Inventor: KOBAYASHI TSUTOMU
IPC: B65D1/02
Filed: 1993-05-11
Granted: 2005-10-11
Abstract: The present invention relates to a laminated bottle, wherein said bottle comprising at least two layers, i.e., an outer layer and an inner layer in order to prevent it from being collapsed under a reduced pressure inside the bottle, said inner layer of the body portion and the outer layer adjacent to the inner layer being made to be freely peelable each other, said inner layer and outer layers being at least partially bonded together. As the inner layer is peeled away from the outer layer and collapsed in a bag-like configuration, when the contents in said bottle are vaporized or such contents are emptied by means of pump, and therefore deformation of the outer layer is not likely to occur. The pump device which is to be inserted into the mouth portion of the bottle may form a space which serves to prevent the bag made from the inner layer from making a close contact with the pump suction device.

Abstract: An absorbent pad for use with meat and poultry  products  in  retail  sale  packages  has  a laminated tissue absorbent mat sandwiched and sealed between upper and lower plastic sheets.  The pad is perforated by penetration of perforating pins entirely through the pad to develop a series of holes for the passage of liquid from the meat package into the absorbent mat inside the pad.  A myriad of outwardly projecting tufts of tissue material are developed along the underside of the pad by the perforating pins.   These tufts develop a wicking effect which enhances the capillary action of the tissue layers inside the pad. Methods of fabrication of the individual pads and continuous linear absorbent sheet material are also disclosed.

Title: Linear actuation drive mechanism for power-assisted chairs
Inventor: KOMOROWSKI KARL JOSEPH JR
IPC: A47C1/0355
Filed: 1994-10-14
Granted: 2005-03-29
Abstract: The chair of the present invention includes a power-assisted linear actuation drive mechanism having a lead screw nut which is linearly movable upon rotation of a power screw for selectively actuating the lift and tilt linkage mechanism for causing forward lifting and tilting movement of the chair when the motor is operated in a first direction. Rotation of the screw shaft in a second opposite direction acts to lower the chair to the normal seating position. Continued rotation in the second direction causes a first cam block pivotably mounted to the lead screw nut to engage a first follower assembly for causing extension of the leg rest assembly.   Further rotation in the second direction causes a second cam block pivotably mounted to the lead screw nut to engage a second follower assembly for causing reclining movement of the chair. This sequential operation of the leg rest assembly and the reclining linkage are independent and may be easily disabled to selectively eliminate either of the features.

Abstract: A clothes drier according to the present invention can minimize failures in a sensor and can satisfactorily detect drying processing irrespective of the environment. In the clothes drier, an atmospheric temperature sensor 44L for detecting the substrate temperature required to determine the termination of the drying processing is disposed outside a circulating duct 18 and is mounted on a control substrate 42 having a thermal capacity on which a microcomputer for controlling operations performed by the clothes drier is mounted. Since the sensor 44L is provided outside the circulating duct 18, the sensor 44L is less affected by dust and water, as compared with a case where it is provided inside the circulating duct 18.      Consequently, it is possible to minimize defects caused by failures and aging of the atmospheric temperature sensor 44L. In addition, the temperature of the control substrate 42 having a large thermal capacity is detected, thereby to make it possible to satisfactorily determine the termination of the drying processing irrespective of the environment. Further, the sensor 44L and the microcomputer are disposed on the same control substrate, thereby to make it possible to reduce the length of a signal line as well as simplify wiring work (Fig. 2, Figs. 3A and 3B).

Abstract: A gauge wheel assembly includes a gauge wheel arm that straddles the rig tube and is supported on the tube by two bushings inserted through holes on either side of the tube. The bushings contact each other near the center of the tube to provide a solid or hard joint which permits the pivot bolt to be tightened without crushing the sides of the tube.  The bushing has protrusions that are pressed into the tubing wall during installation and thereby prevent bushing rotation.  Two different straps at the lower end of the wheel arm permits at least three different combinations of gauge wheels to be quickly and easily mounted.  A compact and easily accessible depth adjusting crank is supported entirely above the rig tube.  A depth indicator projects from the crank trunnion mounting on the upper end of the wheel arm to provide an indication of depth adjustment.

Title: Rotationally invariant trellis coding incorporating transparent binary convolutional codes
Inventor: HEEGARD CHRIS
IPC: H04L27/20
Filed: 1995-11-30
Granted: 2001-02-13
Abstract: A rotationally invariant trellis coder is provided for encoding data to be transmitted using a two-dimensional symbol modulation.  A precoder, provided at the transmitter, processes data such that a counterpart postcoder at the receiver will provide an output that is invariant to any multiple of a 90° rotation.  An encoder encodes the precoded data using a transparent binary convolutional code, which can be a punctured or unpunctured code.  The encoded data is mapped to a two-dimensional signal space having a plurality of signal points.  The signal points are labeled with unique binary codes in which the two least significant bits, denoted by (Ij, Qj), are permuted and partially complemented to (?j, Ij) for each 90° phase rotation around the signal space.  The remaining most significant bits for each point, if any, are invariant to such rotation.  The postcoder provided at the receiver inverts the precoder and is feedback-free, thus limiting error propagation.
