Patent EP-0245203-A2 (EP)
Inventor: EAST GREGORY M
IPC: F16D15/00
Filed: 1987-04-29
Abstract: This invention is embodied in a mechanical clutch capable of transferring a large force or torque from an input member to an output member by the application of a very small control force or torque. This clutch is capable of performing many non- slipping power engagements per second. When configured as a following mechanical servo, this clutch becomes the crux of a continuously variable transmission (CVT) suitable for automotive use. In such use, mechanical power may be transferred very precisely by a controlling power of much lower level than the power being transmitted through the clutch mechanism. The automotive literature shows many articles which propose 20%-25 % fuel efficiency improvement obtained by using a continuously variable transmission (CVT). 
     Today's commercial CVT's have a stepless changing mechanical advantage which is a function of variable pitch diameter ratios, as with wide Vee belts, traction drives. All of these have insufficient power ratings for automotive use. The hydrostatic CVT's operate by the exchange of variable fluid volumes, and have power ratings to drive earth movers. But they suffer from low efficiency and high cost.

Abstract: A lubricating oil composition having improved temperature characteristics is disclosed, containing: (A) a base oil having a kinematic viscosity at 100°C of 1.5 to 50 cSt, a pour point of -25°C or lower and a viscosity index of at least 60; (B) an ethylene-α-olefin copolymer having a number average molecular weight of 1,000 to 8,000; and (C) at least one additive selected from an extreme pressure agent, an anti-wear agent, an oiliness agent and a detergent dispersant. The present composition has a high viscosity index and exhibits good temperature characteristics, particularly low temperature characteristics, and further is excellent in shear stability, extreme pressure properties, wear resistance, detergency and so on. Thus it is useful as a gear oil for cars or industrial machines, an internal combustion engine oil, an automatic transmission oil and so on.

IPC: G01N21/956

Abstract: An inspection system (10, 100) employs a Fourier transform lens (34, 120) and an inverse Fourier transform lens (54, 142) positioned along an optic axis (48, 144) to produce from an illuminated area of a patterned specimen wafer (12) a spatial frequency spectrum whose frequency components can be selectively filtered to produce an image pattern of defects in the illuminated area of the wafer. Depending on the optical component configuration of the inspection system, the filtering can be accomplished by a spatial filter of either the transmissive (50) or reflective (102) type. The lenses collect light diffracted by a wafer die (14) aligned with the optic axis and light diffracted by other wafer dies proximately located to such die. The inspection system is useful for inspecting only dies having many redundant circuit patterns. The filtered image strikes the surface of a two-dimensional photo-­detector array (58) which detects the presence of light corresponding to defects in only the illuminated on-axis wafer die. Inspection of all possible defects in the portions of the wafer surface having many redundant circuit patterns is accomplished by mounting the wafer onto a two-dimensional translation stage and moving the stage (40) so that the illuminated area continuously scans across the wafer surface from die to die until the desired portions of the wafer surface have been illumi­nated. The use of a time delay integration technique permits continuous stage movement and inspection of the wafer surface in a raster scan fashion.

Abstract: A display area control system having a function of switching a display mode and inhibiting alteration of the switched display mode in a plasma display apparatus is provided. When a screen of the selected display mode is smaller than a physical screen of the plasma display apparatus, the screen is displayed at the center of the physical screen of the plasma display apparatus. A data non-display area on the physical screen is displayed at a low luminance level in correspondence with a boundary display of a CRT display apparatus, so that a non- display area of an effective display screen can be clearly distinguished from the data non-display area.

Abstract: A variable discharge high pressure pump (7) for pumping a fuel into a common rail (4) of a common rail type fuel injection system has a plunger (15) reciprocable in a cylinder bore and a pumping chamber (16) defined between and end face of the plunger and the inner peripheral surface of the cylinder bore. A solenoid valve (30) has a valve member (38) movable into an open position in which the valve member is moved out of engagement with an associated valve seat (37) into the pumping chamber when the solenoid valve is deenergized. When the solenoid valve is energized, the valve member is moved into a closed position in which the fuel pressure in the pumping chamber acts on the valve member to urge the same into engagement with the valve seat. The plunger (15) is of a simple cylinderical structure free from any lead formed therein.

Abstract: A fluid pressure control valve and a fluid control system (such as for beverage dispensing) with such a valve has a beverage passage (3), pressure fluctuations in which are detected by a diaphragm (17) to displace a sensing member (15) axially against spring loading (23). Spring (23) reacts on thrust member (22) which is adjustable axially through a cam mechanism (25/26) to vary the biasing force of spring (23). A valve member (20) spring loaded at (21) relative to thrust member (15) normally closes an exhaust port (19) to an air or other gas passage (5) through which gas passes under pressure to be injected into the beverage from passage (3). An increase in beverage pressure in passage (3) displaces sensing member (15) to increase the spring biasing (21) on the closure member (20) and reduce the proportion of air which can escape to atmosphere from passage (5) through exhaust port (19) to provide an increase in air flow into the beverage. A reduction of pressure in passage (3) reduces the spring biasing (21) to permit a greater proportion of air to escape from passage (5) through exhaust port (9) and thereby reduce the proportion of air which is introduced into the beverage. 
     The control valve can include a temperature sensitive unit responsive to temperature of beverage in passage (3) and which reacts to adjust the force of biasing spring (21) independently of pressure in the passage (3). 
     Plunger (51) can be depressed manually to close the exhaust port (19) temporarily and thereby maintain maximum air pressure in the passage (5).

Abstract: A protective layer of BaSO₄ or BaSO₄ mixed with SiO₂ is applied in suspension to the inner surface of the glass discharge tube or envelope of a gas discharge lamp of the metal vapour type. The protective layer prevents contact, e.g., of mercury in the discharge chamber with amalgam-­forming substances present in the glass surface of the lamp discharge tube. In addition, the crystals of the protec­tive layer re-reflect shortwave ultraviolet radiation back to the layer of luminescent substance, thereby to generate visible light and increasing the efficiency of the lamp. The protective layer results in a marked decrease in the hitherto accepted reduction in the lamp luminance in rela­tion to lamp burning time.
