Title: Address conversion replacing circuit and method
Inventor: WATKINS JOHN E
IPC: G06F12/10
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To shorten the time when the entry items remain in an ATU and also to replace only the contents of valid entry items by setting the entry items so as to reflect an invalid state when an event such as a page end event, etc., is detected. SOLUTION: A replacing circuit includes an updating control circuit 600 and a flush control circuit. These included circuits collectively decide the specific CAM/RAM entry items of an ATU to store the new address conversions respectively, decide the specific preceding address conversions to be replaced if all current address conversions included in the ATU are being used and also support many functions to eliminate the unnecessary address conversions, etc. The circuit 600 consists of an ATU replacement element 610, a CAM address encoding circuit 620, a selection element 630, an increment circuit 640 and a CAM address decoding circuit 650.

Title: Manufacture of moisture sensor
Inventor: MAEDA SHOSAKU
IPC: G01N27/12
Filed: 1985-08-28
Abstract: PURPOSE:To enable the formation of a thin silicon film supported on a silicon substrate, by forming an SiO2 on one main surface of the silicon substrate while forming a mask layer having an opening on the other main surface. CONSTITUTION:A silicon substrate 1 being cleaned up is heated in the atmosphere to let SiO2 films 2A and 2B grow on both the main surfaces thereof. Then, a proper size of opening 3 is made in one SiO2 film 2B by photolithography and etching. Moreover, the substrate 1 is removed corresponding to the portion of the opening 3 by an anisotropic etching with the SiO2 films 2A and 2B as mask, leaving a thin SiO2 film 2A alone. Then, Pd thin films 4A and 4B are formed on both the surfaces by evaporation. Thereafter, the substrate 1 is cut into individual chips to support a thin SiO2 film 2A at the peripheral part with the substrate 1. This also produces a sensor chip made up of the SiO2 film 2A sandwiched between the Pd thin films 4A and 4B. The Pd thin films 4A and 4B serve as electrodes. Thus, a thin SiO2 film can be formed.

Title: Multilayered film optical wavelength filter
Inventor: SAKAGUCHI SHIGEKI
IPC: G02F1/03
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To provide a variable wavelength filter having the wavelength characteristics in a narrow band by periodically and repeatedly laminating an electro-optic material and a dielectric material to obtain a multilayered film and varying the filtering wavelength with an electric field applied. SOLUTION: The variable wavelength filter has a multilayered film structure produced by periodically and repeatedly laminating an electro-optical material P and a dielectric material G. The structure of the multilayered film is expressed by [PG]m[2P][GP]m, wherein (m) is the number of repetition. In this structure, the period of laminated layers is symmetric for the [2P] part which is the center of lamination. As for the material P, barium titanate(BT) is used, and as for the material G, silicon dioxide is used. An optical axis of BT is aligned along a lamination direction (z axis), an electric field is applied in the x-axis direction perpendicular to the optical axis, and light waves with the electric field oscillating in the xz plane are used.  When the electric field is applied in the x-axis direction, the refractive index of BT changes according to the intensity of the electric field applied and to the crystalline direction.

Title: Preparation of w/o/w type emulsion
Inventor: KITAOKA RIYOUICHI
IPC: A61K8/00
Filed: 1982-10-29
Abstract: PURPOSE:To prepare the titled emulsion excellent in stability, by a method wherein an S/O type emulsion obtained by dispersing a gel consisting of oleophilic surfactant and water in an oil phase is prepared and subsequently emulsified with a water phase. CONSTITUTION:A gel is formed from an oleophilic surfactant with an HLB value of 9 or less (e.g., sorbitan fatty acid ester) and water and dispersed in an oil phase such as a castor oil to obtain a W/O type emulsion which is, in turn, mixed and emulsified with a water phase to be brought to an external water phase. In preparing the gel in this process, when a proper amount of an acid (e.g., citric acid) and/or salts thereof are added, the formed gel becomes firm and, as the result, water droplets are stably held in dispersing said gel in the oil phase. In emulsifying the W/O emulsion and the external water phase in the above mentioned, when an emulsifier aid (e.g., cetanol) is added, it is stably oriented at the interface with the external water phase and the titled emulsion becomes more stable.

Title: Parts conveyer
Inventor: KINOSHITA TOSHIO
IPC: B65G15/42
Filed: 1993-07-30
Abstract: PURPOSE:To lessen contact resistance between parts and a track so that even parts made of such as rubber having large frictional coefficient can be smoothly sent out and conveyed by forming a plurality of projections on the surface of the track for sending out the parts with vibrations fed from a vibration generating unit. CONSTITUTION:When pulsating voltage is fed to a electromagnet 3 from a slidack controller 1, vibrations are transmitted to a vibrating leaf spring 5 and to a spiral bowl 6 as vertical vibrations and angular vibrations about a vertical shaft. Numerous projections 10 formed of self-supporting fibers and inclined in the direction of sending out parts 8 are formed on a track 7 on a spiral bowl 6, so that the parts 8 are sent forward from the track 7 by vibrations in the same direction as the direction of inclination of the projection 10. When the amplitude of the surface of the track 7 returns in the opposite direction from the progress direction of the parts 8, the parts 8 are separated from the tip of the projection 10 on the track 7 by an inertia force to float up and relatively advance. The parts 8 can be transferred by the repetition of such movement.

Abstract: PURPOSE:To obtain a small-sized and lightweight frame by allowing a large compression retaining force to be taken by a main bearing and allowing a small magnetic force to be taken by the frame by fixing a cylinder block constituting a compressor part to the main bearing. CONSTITUTION:A cylinder block which is arranged in a sealed container 1 and constitutes a compressor part 3 is fixed onto the upper surface of a main bearing 11 through an installation part 21 integrally installed onto the under surface, by a bolt 22.

IPC: C07C5/48
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To produce ethylene with high selectivity even when the concn. of ethane in reactive gas and the rate of conversion of ethane are increased by using oxide contg. Sn and W as the catalytically active component of a catalyst for production of ethylene by oxidation of ethane. SOLUTION: An Sn-contg. soln. is impregnated into a carrier such as alumina or silica and the carrier is fired after drying. A W-contg. soln. is then impregnated into the carrier and the carrier is fired after drying to obtain an Sn-W catalyst contg. Sn and W in an atomic ratio of (1-99):(99-1). This catalyst ensures a high rate of conversion even under relatively mild conditions and under high- speed reaction conditions and can maintain high catalytic activity for a long time. As a result, even when the concn. of ethane in reactive gas is increased to >=10% and the rate of conversion of ethane is increased to >=1%, >=60% selectivity of ethylene is attained.
