Patent GB-2276034-A (GB)
Title: Manufacture of grating structures
Inventor: PHILLIPS NICHOLAS JOHN
IPC: H01S5/12
Filed: 1993-04-08
Abstract: An embossing tool (40) is constructed with the patterning appropriate for the construction of the optical grating structure of a DFB laser. This tool is advanced into the surface of a UV-curable resin layer (51) applied to the surface of a semiconductor slice (50), and the resulting embossed portion of the resin layer (51) is thinned to create ridges (80) separated by intervening windows to form a mask for etching of the channels (81) of a DFB grating structure in the surface of the underlying semiconductor slice. <IMAGE>

Title: Hairbrush with a detachable handle
Inventor: VASEY MARK EDWARD
IPC: A45D6/00
Filed: 1994-04-28
Abstract: A hair brush comprises a handle 2 which connects and disengages from the brush head 1, allowing the head 1 to be left in someones hair. A plurality of brush heads may therefore be applied through out the hair, during blow drying with a hand held dryer. The handle can connect and disengage to a variety of different sized brush heads, from a set containing a comprehensive selection according to the length of the hair to be blow dried. Connection and release of the handle 2 from the head 1 is achieved by pressing a button 3 on the handle 2, which subsequently releases a location pin 4 from the brush head 1. The brush heads are stored in a colour coded set designed for easy identification and stenlisation. The primary objective is that this brush can be used with the use of one hand only, so the other hand is free to hold the hair dryer during blow drying. <IMAGE>

Title: Extended interaction output circuit
Inventor: BEGUM SYEDA RASHEDA
IPC: H01J25/11
Filed: 1994-06-17
Abstract: An extended interaction output circuit is provided for interacting with a modulated electron beam e.g. from a relativistic klystron and for outputting RF electromagnetic energy. The circuit comprises a plurality of linearly disposed cavities (34, 36, 38, 42) having an axially extending beam tunnel (64). Each of the cavities is separated by an annular disk (46, 54, 58) having a hole (48, 56, 62). The hole diameters increase in steps so that the impedance of the successive cavities decreases along the axial extent of the circuit. The diameter of the successive cavities is also increased to maintain the same mid-band resonant frequency. The linearly disposed cavities act as an RF filter having successively tapered impedances to reduce reflections of the electromagnetic energy propagating through the circuit. The gap-to-gap distance between successive cavities is selected to provide a 90 degree phase shift of the beam in order to maintain synchronous operation between the beam and the wave at the mid band frequency. <IMAGE>

Title: Method of manufacturing a printed circuit board
Inventor: NAKASHIMA KUNJI
IPC: G03F7/20
Filed: 1994-06-30
Abstract: A method of manufacturing a printed circuit board comprises exposing to parallel light, a photoresist layer 30 formed on a three-dimensionally molded substrate 10 through a conductive layer 20 using a planar photomask 40 which is provided with a mask pattern and a light-transmissive pattern 42, the pattern varying in width (W1, W2, W3) depending on the distance D between the mask and the photoresist in order to give to the photo resist layer an exposed pattern of an intended width L1 in correspondence to the light-transmissive pattern. Alternatively 2 or more masks can be used placed at the appropriate heights above the photoresist surface (Figs. 4 - 13) or 2 exposures can be made using blind masks and masks at different heights (Fig. 14). A further alternative is to use a thick mask with the same pattern on the top and bottom sides (Fig. 17) or two masks with identical patterns spaced from each other, the lower mask having a reflective coat on the pattern (Figs. 15 - 16). Since the light-transmissive pattern of the photomask is configured so as to reduce the influence of diffraction of the parallel light beam at the light-transmissive pattern, the circuit pattern can be precisely formed on the substrate. <IMAGE>

Title: Remote terminal emulator
Inventor: PACKER ALLAN N
IPC: G06F13/10
Filed: 1996-07-05
Abstract: A remote terminal emulator (RTE) is provided in which substantially all of the time elapsing during an emulated use of a computer system under test is categorized and reported. The time required by the computer system under test to respond to command signals transmitted by the RTE is recorded as a receive time and is measured from completion of the transmission of the command signals to recognition of a pattern specified by the RTE as signifying completion of the response by the computer system under test. As a result the receive time recorded reflects the time required by the computer system under test to (a) process and carry out the command transmitted by the RTE and (b) transmit response data back to the RTE. The RTE accurately measures and reports the measured user think time to provide important information regard the authenticity of the emulated use, when compared to actual user think times measured during actual use of the computer system under test by actual users, and the relative importance of the processing capacity of the computer system under test. The time during which the RTE processes information, causing emulation of use of the computer system under test to be suspended, is accurately measured as application processing time and is reported to the user of the RTE. Substantially all of the time elapsing during the emulated use of the computer system under test is reported to the user of the RTE to provide the user of the RTE more complete and revealing information regarding the performance of the computer system under test.

Title: Electrostatic spray gun for powder coating
Inventor: YANAGIDA KENZO
IPC: B05D3/00
Filed: 1997-06-03
Abstract: Voltage generated by a high voltage generator 21 is applied to corona electrodes 19, and powder supplied through a passage 14 collides against a diffuser main body 12 while being moved in a vortex by air ejected from ports 38 and is ejected from an annular nozzle opening 15. After the powder is charged by the ions generated by the corona discharge, it is sprayed at an object to be coated. Free ions generated by the corona discharge are trapped by electrodes 27. Adhesion of the powder is prevented by the expulsion of compressed air through a diffuser front cover 17 and an outer cylinder cover 22, each composed of porous material, and the ejection of compressed air from a nozzle hole 28a. Utility may be in production of automotive clear top coats.
