Title: Stress plate with angled hole
Inventor: HEMPFLING DAVE C
IPC: E04D3/36
Filed: 1997-11-28
Abstract: A stress plate for use with a threaded fastener for securing relatively soft insulation to a solid base, such as in a roofing environment, includes a generally planar main body, and a hole on the main body configured for receiving the fastener. The plate is configured so that the hole is angled relative to a vertical axis of the plate for accommodating threads of the fastener so that the fastener is maintained in a generally perpendicular orientation to the main body upon the engagement of the threads of the fastener in the hole. In the preferred embodiment, the threads of the fastener have a helix angle, and the hole, which is formed in a conical depression in the plate, is angled at the same angle as the threads of the fastener.

Abstract: It is thought that one-third of the average person's life is spent sleeping in bed. In the adult, this lordosis extends from the atlas to the second thoracic vertebra. Most cervical pillows are designed to support the cervical lordosis while resting or sleeping. Proper use of the "right" kind of pillow during sleep may be important in improving the posture of the whole body.      Health practitioners know from their clinical experience that not all patients can adapt to the contoured cervical foam pillow.      While almost half of patients "fall in love" with the pillow, some have no desire to use the pillow.      This pillow (Universal Pillow) is invented by considering the fact that each individual has different neck and shoulder size.      Although introducing certain curvatures in a pillow promotes proper head and neck positioning, size of the pillow's height and curvature has critical rule in achieving comfort and support. Moreover, the position of body and consequently head and neck while lying on the pillow has been ignored in the previous inventions. They have simply assumed that the same curvature is sufficient for lying supine(on the back), lateral recumbent(on the side) and prone(on the stomach).      Most pillows offer an specific height throughout the entire pillow which could alter the ideal position for head/neck and cause discomfort when the user changes sleep posture from supine position to lateral recumbent position or vice versa. Due to the difference in neck thickness and shoulder width, a different height of pillow is required when the person is on his/her back or side. This problem is addressed in this invention by providing a shorter height throughout the middle curved area for supine sleeping and a higher height on the either side of the curved area for lateral recumbent sleep posture. Moreover, this invention has four sides of increasing height. Although this pillow is not totally customized for each person, it allows the individual to choice one of the four possible heights.      This pillow also contains a slightly protruded rectangular wedge in the middle third of each of the four sides. The wedge shape protrusion provides the lower neck area with an extra support.

Title: Wafer processing apparatus, wafer processing method, and soi wafer fabrication method
Inventor: SAKAGUCHI KIYOFUMI
IPC: H01L21/304
Filed: 1998-02-02
Abstract: A wafer is supported while being rotated by four wafer rotating rods having grooves.  The wafer rotating rods are rotated by a driving force transmitted from a motor installed outside a wafer processing bath.  An ultrasonic bath is arranged below the wafer processing bath, and ultrasonic waves generated by an ultrasonic source are transmitted to the wafer processing bath.  The ultrasonic waves are efficiently transmitted to the wafer because the wafer is supported only by the wafer rotating rods.

IPC: A01K1/10
Filed: 1998-11-10
Abstract: A head gate for use in controlling access of livestock to feed exposed at an open end of an elongated agricultural storage bag of the type formed of tubular flexible sheet plastic. The head gate includes a framework having a central portion which extends across in front of the open end and is provided with a number of openings sized to permit the livestock to reach through and feed from a face of compacted feed within the bag, the framework being mounted on skids to allow the head gate to be shoved towards the open end of the bag. Sheet plastic storage rolls are mounted on the framework and have a drive system to rotate the rolls relative to the framework for gathering the sheet material which had formed the bag and becomes excess as the feed recedes from the open end. The head gate allows for use of the feed directly from the bag with little labour involved while maintaining the feed clean and preventing wastage. After the stored food of the bag is completely consumed the sheet plastic of the bag which has been maintained in a neatly stored condition can be easily removed for disposal.
