Title: Diffraction grating and manufacturing method thereof
IPC: G02B5/18
Filed: 1988-12-28
Granted: 1993-08-24
Abstract: ABSTRACT OF THE DISCLOSURE A diffraction grating has a reflection film formed on a photosensitive layer disposed on a substrate through exposure followed by development and the groove profile thus formed has a configuration distorted from a sinusoidal form because the sensitivity curve of the photosensitive layer is of the second order non-linearity to the exposure amount.  With the groove pitch expressed by d, K = 2 .pi./d, the coordinate perpendicular to the groove direction taken as x, and the groove profile .pi.(x) expressed as .pi.(x) = h [sin (Kx) + .gamma.sin (2Kx - 90°)], the parameters h, .gamma. and .PHI. satisfy as follows: 0.26 ? 2h/d  ? 0.52 0.05 ?  .gamma.   ? 0.32.          The wavelength region to be used is normalized by the groove pitch d as 0.67 ? .lambda./d ? 1.1.5.  When an incident angle is expressed by .THETA. and the first order Littrow angle is expressed by .THETA.L, the amount to be used is carried out in such a region that satisfies the following expression:   .THETA.L - 5° ? .THETA. ? .THETA.L + 5°.

Abstract: ABSTRACT OF THE DISCLOSURE    This invention pertains to a lamp socket assembly for use in automotive applications and the like.  The assembly includes a housing, a contact insert, and a body.  The contact insert is captured in the cavity of the housing by the body.  The body is welded to the housing.  Lugs on the body secure the assembly to a panel.  A seal is placed between a flange on the housing and the panel to seal the assembly to the panel.  Contacts are retained in the contact insert by engagement of U-shaped portions in slots of the contact inserts.  Blade terminals are inserted through windows in the housing, contact insert, and contacts to interlock the terminals with the contacts and to keep the contacts secured in their positions.  A socket connector is sealingly secured to the housing and prevents moisture from entering the housing.  In an alternative embodiment, no socket connector is provided but the blade terminals are crimped to wires for connecting the socket assembly to a source of electric power.  In still another embodiment, the socket connector includes a protrusion for interlocking the body and the base together.

Abstract: A conveying device directs printed products past a stationarily arranged ink jet printer. A control system initiates a printing operation by the printer each time a printed product passes through the effective printing zone or region of the printer. The conveying device comprises an individual conveyor equipped with gripper units arranged in spaced relationship from each other, each of which is structured to take-up or engage one printed product. The control system includes a pulse generator driven by the individual conveyor and transmits a control pulse for each one of the gripper units. The control pulse is suppressed by a monitor responsive to empty gripper units. Since the printed products are conveyed by the gripper units, their reference position relative to the conveying device is defined over the entire product conveying path. The control signal initiating the printing operation thus can be utilized for initiating other operations after passing through a delay element.

Abstract: 1374289 Surface treatment of wood E G L ERIKSSON 3 Nov 1971 [3 Nov 1970] 51040/71 Heading DIP A method for treating the surface of wood, comprises pretreating the wood with a liquid hydrophilic substance substantially free of solvent and which facilitates penetration of the wood surface by an impregnation agent, the substance being caused to harden thereafter by subsequent treatment with the impregnating agent which reacts with the substance to form a polymer. The substance may be phenol or resorcinol. The agent may be an aqueous solution of hexamethylene tetramine, melamine formaldehyde or an intermediate reaction product of phenol and paraformaldehyde. Disproportionate penetration of the end surfaces relative to the other surfaces is prevented by initially applying an aqueous melamine resin to the end surfaces. This reacts with the phenol during the pretreatment to form a phenol insoluble polymer which prevents further penetration of the end surfaces. The phenol pretreatment may be effected at elevated temperature. Sulphuric acid or stannous chloride may be added to the phenol. The pre-treatment may be followed by a vacuum treatment. The subsequent impregnation may be at elevated temperature and pressure. This may be followed by a heat treatment which may be in two stages (a) oven at 80-140‹C for 1-2 hours and (b) hot press at 130-180‹C for 5-20 min. The surface finish is durable, abrasion-resistant and may be water repellant.

Abstract: The insulated window construction is characterized in having a substantially uniform heat transition coefficient. The uniformity of the heat transition coefficient is obtained by increasing the distance between the window panes and the heat resistance in the edge region of the window is matched to that in the region of the window area which is undisturbed by the edge. The edge region is formed by a frame which has a pair of separate metallic frame members which are joined together and spaced apart by non-metallic webs so as to define an insulation path of at least 0.8 times the clearance between the panes.
