Title: Force feedback and texture simulating interface device
Inventor: KRAMER JAMES F
IPC: G06F3/033
Filed: 1991-01-30
Granted: 2001-07-24
Abstract: A man-machine interface is dis-closed which provides force and texture information to sensing body parts. The interface is comprised of a force actuat-ing device (900) that produces a force which is transmitted to force applying de-vice (902). The force applying device ap-plies the generated force to a pressure sensing body part. A force sensor (909) on the force applying , device measures the actual force applied to the pressure sensing body part, while angle sensors (911) measure the angles of relevant joint body parts. A computing device (911) uses the,joint body part position informa-tion a determine a desired force value to be applied to pressure sensing body part.     The computing device combines the joint body part position information with the force sensor information to calculate the force command which is sent to the force actuating device. In this manner, the computing device may control the actual force applied to a pressure sensing body part to a desired force which depends upon the positions of related joint body parts. In addition, the interface is comprised of a displace-ment actuating device (901) which produces a displacement which is transmitted to a displacement applying device (902) (e:g.; a texture simulator). The displacement applying device applies the generated displacement to a pressure sensing body part. The for-ce applying device and displacement applying device may be combined to simultaneously provide force and displacement infor-mation to apressure sensing body part:

Title: Quadrupole electrode and process for producing the same
Inventor: HIROKI SEIJI
IPC: H01J49/42
Filed: 1992-09-07
Granted: 1998-09-29
Abstract: The present invention relates to improvement of a quadrupole electrode for use in a mass spectrometer or the like, in which two pairs of electrode rods 1, 2, 3 and 4 formed in such a manner that the section of the opposed face of each rod is hyperbolic or circular, and each electrode rod is made of a ceramic and the surface of the electrode is coated with a coating layer 5 of a conductive metal.  Further, the present invention relates to a production process, characterized by incorporating such four electrodes at predetermined intervals. Since the electrodes are mainly made of a ceramic which is easily formable with a high dimensional accuracy, the adjustment of the positional relationship between the electrodes during assembling can be made without much effort, which enables a quadrupole electrode having a high performance to be provided with a good reproducibility at a low cost.

Title: Thin offset drawer slide with progression roller
Inventor: KOVARIK FRANZ
IPC: A47B88/04
Filed: 1993-06-04
Granted: 2002-04-23
Abstract: A thin profile drawer slide apparatus for slidably supporting a heavy drawer in furniture, comprising symmetrical, identical channel members for slidably attaching the apparatus to a drawer and an article of furniture, a plurality of bearings slidably retained in the channel members by bearing retainers, and by an intermediate slide member. The intermediate slide member comprises the unitarily formed combination of a generally vertical central wall, a first bearing raceway joined to an end of the central wall, and a second bearing raceway joined to an arcuate wall extending angularly outwardly from the first bearing raceway, whereby the first and second bearing raceways are vertically and angularly separated. The ball bearings are arranged in four linear, slightly offset sets. Use of a single intermediate slide member with raceways for four separate sets of bearings provides a thin, strong drawer slide for carrying heavy loads. The central wall of the intermediate slide member comprises a generally rectangular window with a progression roller mounted therein on a vertical axis of rotation. The roller exerts friction on the inner faces of the channel members by compression against the inner faces when the roller is moved. Each channel member comprises at least one roller clearance window. Edges of window act as a detent on the roller and also urge the slide closed when the slide is brought to rest with the roller against one of the edges. The windows relieve compression of the roller when the slide is fully closed.
