Title: Method for selectively scaling a field emission electron gun and device formed thereby
Inventor: CHANG TAI-HON P
IPC: H01J3/02
Filed: 1992-04-02
Abstract: METHOD FOR SELECTIVELY SCALING A FIELD EMISSION      ELECTRON GUN AND DEVICE FORMED THEREBY            ABSTRACT OF THE DISCLOSURE      The present invention is directed to a method for selectively scaling the dimensions of a field emission electron gun. The electron gun includes a field emission tip followed by a dual electrode immersion lens. The lens consists  of  two  planar  electrodes  separated  by  a dielectric layer. A well defined circular hole is present at the center of each electrode and the dielectric layer. A high scaling factor is applied to the region consisting of the first electrode and the emission tip, reducing the first  electrode  thickness  and  bore  diameter  and  the distance  between  the  tip  and  first  electrode  to  the micrometer range. A weaker scaling factor is applied to the bore diameter of the second electrode and the spacing between the electrodes  such that the  second electrode bore diameter and distance between the electrodes are approximately  equal  and  are  greater  than  the  first electrode thickness and bore diameter and the distance between the tip and first electrode.

Title: Hydraulic shape memory material stress to hydraulic pressure transducer
Inventor: WHITEHEAD CHARLES A
IPC: F16D65/28
Filed: 1990-08-06
Abstract: A hydraulic shape memory material force converter is provided comprising a shape memory material. The force converter utilizes hydraulic units and a hydraulic fluid. The hydraulic unit is changed from a first position to a second position when the shape memory material, connected at one end to one end of the hydraulic unit and its other to a fixed point or a second end of the hydraulic unit, changes from a martensitic to an austenitic state upon heating. The hydraulic fluid responds to the movement of the hydraulic unit by moving from the hydraulic unit to a receiving device, which receiving device performs work due to the motion of the hydraulic fluid. Upon cooling the shape memory material to change it from the austenitic state back to the martensitic state, the hydraulic unit returns to its original position, with a biasing means being provided to return the hydraulic unit to its rest position.

Title: Method and device to facilitate the cognitive development of alternative response behaviour
Inventor: BORG CHARLES
IPC: G09B7/04
Filed: 1992-06-23
Abstract: This invention relates to a device and method for assisting people in changing their behaviour and in particular assisting people to stop performing an acquired behavioural response such as using tobacco products, using alcohol, or over-eating. The device and method interrupt a user's acquired behavioural response to stimuli before a decision regarding a course of action is made. A set of symbols representing alternative responses to the acquired behavioural responses is then displayed to the user to encourage the user to perform an alternative response.      The user acknowledges whether the acquired behavioural response was performed or whether one of the alternative behavioural responses was performed. The device records the number of times either response was performed for later analysis and record keeping.

Title: Process for producing fine flaky alumina particles and alumina-based plastic material
Inventor: SHIBASAKI YASUO
IPC: C01F7/021
Filed: 1992-07-08
Abstract: The present invention provides a process for producing fine flaky alumina particles which are suitable as a raw material for ceramics, a pigment for paint and etc., wherein aluminum hydroxide or alumina hydrate having a particle size regulated to the order of submicron is subjected to a hydrothermal treatment in water or an aqueous alkali solution at a temperature of 350°C or above and under a pressure of 200 kg/cm2 or below.  The present invention further provides an alumina-based plastic material which is produced by kneading the aforesaid fine flaky particles with an organic water holding material and water. Methylcellulose, polyvinyl alcohol, carboxymethylcellulose, polyethylene glycol, etc. are preferably used as the organic water holding agent. The alumina-based plastic material has a high plasticity, so that there is no need of using a large amount of a binder.  Thus a dense molded article having stable properties can be prepared.

Title: Methods and compositions for the identification, characterization and inhibition of farnesyl protein transferase
Inventor: BROWN MICHAEL S
IPC: C07K5/107
Filed: 1991-04-18
Abstract: Disclosed are methods and compositions for the identification, characterization and inhibition of farnesyl protein transfer-ases, enzymes involved in the farnesylation of various cellular proteins, including cancer related ras proteins such as p21ras. One farnesyl protein transferase which is disclosed herein exhibits a molecular weight of between about 70,000 and about 100,000 up-on gel exclusion chromatography. The enzyme appears to comprise one or two subunits of approximately 50 kDa each. Methods are disclosed for assay and purification of the enzyme, as well as procedures for using the purified enzyme in screening protocols for the identification of possible anticancer agents which inhibit the enzyme and thereby prevent expression of proteins such as p21ras. Also disclosed is a family of compounds which act either as false substrates for the enzyme or as pure inhibitors and can therefore be employed for inhibition of the enzyme. The most potent inhibitors are ones in which phenylalanine occurs at the third position of a tetrapeptide whose amino terminus is cysteine.

Filed: 1991-12-11
Abstract: In Multistation Demand Assigned Time Division Multiple Access Systems digital information is communicated from a head end to a population of oustations so that all the outstations receive the same stream of digital information and select their traffic from it.  Traffic is only sent to and from an outstation when there is a demand for it. As the outstations are at random ranges from the head end it is necessary to know the time of travel for a burst of information so they arrive at the head end sequentially. The traffic dependent free time is consolidated and made available for ranging-in outstations.

The co-extruded article is comprised of at least two dissimilar discrete parts such as a rubber component, referred to herein as the "rubber extrudate," and a thermoplastic component, referred to herein as the "plastic extrudate."  A particular  advantage  of  the  invention  is  that  the  rubber extrudate and thermoplastic extrudate are cohesively joined at their interface.  By cohesively joined, it is meant that the two extrudates stick together tightly without the necessity of a separate  adhesive.     Where  hardness  is  desired  of  the thermoplastic extrudate,  ethylene vinyl acetate is generally preferred.   Where a seal  is desired,  the rubber extrudate comprises ethylene propylene diene rubber,  which provides a suitable seal.

In operation, an incident light beam penetrating the first grating is propagated through the first layer of photosensitive resin, the plate of glass, and the second layer of photosensitive resin. The first and second gratings split this incident beam into a given number of homogeneous light beams outgoing from the second grating. The beam splitter may comprise a plurality of layers of photosensitive resin, each pair of consecutive resin layers being separated by a plate of glass forming a buffer zone between these two layers.
