Title: Controllable selective oxidation on VCSELs
Inventor: STREUBEL KLAUS
IPC: H01S5/183
Filed: 1999-07-24
Abstract: A method for controlling the oxidation of a layer 190 extending in a transverse plane in a vertical cavity surface emitting laser (VCSEL) 10, involves selectively implanting ions into transversely spaced regions 190a of the layer to change the concentration of the oxidisable material. Subsequently the layer is oxidised and the degree of oxidation of the layer varies in a transverse direction between the implanted regions and non-implanted regions of the layer. The layer may be AlAs or AlGaAs, in which case the implanted ions may be Ga ions. Alternatively the implanted ions may be oxygen.

Title: A Container
Inventor: MILAN GUY
IPC: F16K31/00
Filed: 1999-09-17
Abstract: A container with a flow control device comprises a flow prevention valve 9 with a thermostatic actuation means 10 and a cap with flow path 11. When the vessel 8 is filled with a beverage, the flow control device, being incorporated within the lid of the container, is secured to the vessel 8 thereby immersing the thermostatic actuation means 10 in the beverage. If the beverage in the vessel 8 reaches beyond, either higher or lower, a predetermined threshold temperature, the thermostatic actuation means 10 will close the flow prevention valve 9 and hence the flow path 11 thereby preventing the flow of beverage from the vessel to the consumer. Once the temperature of the beverage is no longer beyond the pre-set threshold temperature, the thermostatic actuation means 10 opens the flow prevention valve 9 enabling the flow of beverage from the vessel 8 to the consumer. The container may be a beverage container, with the two main embodiments of the invention relating to baby bottles 1 and disposable cups 8. The flow control device may be able to be dismantled to facilitate cleaning. The thermostatic actuator means 10 may be of any suitable form. Those specifically disclosed are thermostatic bimetal, thermostatic biplastic, memory metal, memory plastic, thermostatic gas strut and thermostatic bellows. The flow control device may incorporate the thermostatic actuator 10, the container outlet and the valve 9 assembly as an integral single component.

Title: Method of treating municipal waste to produce fuel
Inventor: WALLACE BRIAN VINCENT
IPC: C10L5/46
Filed: 1999-10-15
Abstract: A method of treating municipal waste to produce fuel comprises the first step of screening the waste to remove any non-combustible material, and separate it into fractions depending on size. Then the waste is shredded to a first predetermined size and this shredded waste is formed into bales. The bales can be stored until they are required for use. When the bales are required, they are shredded for a second time into particles of a second predetermined size, which is smaller than the first, producing a homogeneous mix of combustible waste. Preferably the size of the waste material after the first shredder is 250mm or less, and after the second shredder it is 25mm or less. By forming the waste into bales it can be stored for use as fuel during periods such as public holidays when no refuse is collected.

Title: Determining the drive letter assignment of a media drive during initial system setup of a computer system
Inventor: MAIA PAUL J
IPC: G06F9/445
Filed: 1999-12-29
Abstract: Manufacturing process code which includes executable instructions for causing the processor of a computer system (10, Fig. 1) to determine a drive letter designation of at least one computer-readable media drive, e.g. a CD-ROM drive or removable cartridge hard disk drive. During the install software phase of a custom built-to-order computer system manufacturing process, whilst the operating system has already assigned drive letter designations to the diskette and hard disk drives, the computer-readable media drive letter designations are not known. The manufacturing process code, which is preferably in dynamic link library (DLL) form (Figs. 2-5), pre-assigns these letter designations, based on a combination of knowledge of how the operating system will eventually assign these designations, and a system descriptor record providing information on which particular components are installed or to be installed in the computer system. The drive letter designations can be determined prior to the operating system desktop becoming fully initialized, so that when computer-readable media drive based software applications are subsequently installed, the drive designations bound to them are the same as those when the computer system is at the desktop, enabling the implementation of shortcuts and menu selections to those applications.

Abstract: PURPOSE: To reduce the capacity of a power supply circuit and the driving force of a ratchet or the like, by dividing type rows and flying hammers into groups corresponding to a plurality of digits and by simultaneously actuating the flying hammers only one piece per group.  
     CONSTITUTION: Type rows are provided on the peripheral surface of a type drum 2 so that the type rows are divided into groups 5aW5d, for example, as to a plurality of digits. In each group, the types of the digits are sequentially shifted in the circumferential direction by the quotient of the phase of one type divided by the number of the digits included in the group. In Fig., the types are shifted by one- third of the phase of one type, and a character pulse is generated at every time when the type drum 2 performs rotation corresponding to one-third of one type. A plurality of flying hammers 6, which are also divided into groups corresponding to those 5aW5d of the type rows, are installed between a printing position (a) and an energized position (b) so that the hammers are biased to the position (b). A  hammer selection mechanism 9 and a group selection mechanism 10, which permit of return to the position (b), coincide with each other to cause the hammer 6 returned to the position (b) to strike the type drum 2.

Title: Resinoid grindstone for cutting work
Inventor: SUZUKI TAKASHI
IPC: B24D18/00
Filed: 1983-01-25
Abstract: PURPOSE:To permit preparation of a thin-edge grindstone by forming the captioned grindstone from a layer formed through electrolplating bond of grinding grains such as diamond and metals such as nickel and a layer formed through chemical plating bond without using a basic member and securing the service life of the grindstone which is equal to that of a sintered grindstone. CONSTITUTION:A metal mold 3 for grindstone is prepared, electrolytically degreased, and applied with mold releasing agent 4 such as chromate, and then applied with codeposition plating of minute grinding grains such as diamond and metals such as nickel. Since, at this time, if thickening is performed only through electro-plating, the dispersion of the thickness of the plated layer is increased as shown by the curve 8, so the plated thickness is kept in a range of 5-10mum and is made uniform. Then, the grinding grains such as diamond are immersed into the chemical plating liquid consisting of reducing agent and metal salts such as nickel, etc. and thick coating 6 through chemical codeposition plating is carried-out. Further, electro-codeposition-plating 7 is applied onto said plating 6, and the grindstone is released from the metal mold 3, and thus a grindstone is prepared. Therefore, the service life can be prolonged, since a basic member is not used, and the accuracy of thickness of the grindstone can be improved by the application of chemical codeposition plating.
