Abstract: In a thermal head apparatus, temperatures of heat generation elements can be individually detected directly so that an abnormal condition of any heat generation element can be detected. A plurality of unit heat generation elements, each formed from a resistor whose electric resistance value varies depending upon its temperature, are arranged in a row. A driving circuit is provided for each unit heat generation element to supply an electric current to the unit heat generation element. A temperature detection circuit is provided for each unit heat generation element, and extracts from the unit heat generation element an electric signal which is obtained as a result of a variation of a resistance value caused by a variation in temperature of the unit heat generation element itself. An abnormal-condition detection circuit is provided for each unit heat generation element, and detects the presence or absence of an abnormal condition of the unit heat generation element from an output of the temperature detection circuit.

Abstract: A pH greater than 7 aqueous ozonized cleaning composition can be used for cleaning a tenacious residue or film from solid surfaces. The cleaning properties can be potentiated by additive materials. Ozone, generated by electrical discharge, can be blended into effective aqueous cleaning compositions that can efficiently clean proteinaceous, oily or carbohydrate soil from a variety of surfaces. Immediately after ozone generation, the ozone containing gas stream comprising ozone and the residual air is injected through a hose into an aqueous potentiating additive containing carrier solution, forming a cleaning soluti on which is applied immediately to a soiled solid surface to remove a contaminating residue or film.

Abstract: Allophanate-modified MDI which is a storage stable liquid at 25°C is produced in two steps. First, a monoisocyanate is reacted with an organic material having about 1.8 or more hydroxyl groups and a molecular weight of from about 60 to about 6,000 to form the urethane. The urethane is then reacted with an isomeric mixture of MDI in an amount such that the resultant isocyanate will have an NCO content of from about 3 to about 28%. The isomeric mixture of diphenylmethane diisocyanate contains from about 0 to about 60% by weight 2,4'- diphenylmethane diisocyanate, less than 6% by weight 2,2'-MDI and the remainder 4,4'-MDI. The prepolymers of this invention are particularly useful in reaction injection molding processes because molded articles having improved flex modulus are obtained.

Title: Leadframe for an encapsulated optocomponent
Inventor: STEIJER ODD
IPC: H01L31/0203
Filed: 1995-10-19
Granted: 2005-03-22
Abstract: In encapsulating an optocomponent a leadframe is used for the electrical connection of the component, the leadframe having a flag, to which the main body of the optocomponent is attached. The flag is located asymmetrically at an outer edge of the leadframe and is, in the encapsulating operation, placed close to a sidewall in a mould cavity in a mould.      Thereby an optical interface of standard type can be obtained in the wall of the capsule. Further, the flag is flexibly attached, by means of zigzag-shaped bridges, to other portions of the leadframe so that the flag and thus the optocomponent will have a possibility to be resiliently and flexibly displaced a little at the positioning thereof the mould cavity in the mould in relation to the other portions of the leadframe, in particular to its outer frame portions and bridge portions. By designing the zigzag-shaped bridges with a suitably adapted width and thickness a controlled elastic restoring force acting on the flag can be obtained and thus on the optocomponent, so that it can be pressed and firmly retained in engagement with positioning means for the optocomponent.

Abstract: A manually closable collar for a vacuum cleaner bag is adapted to be secured to an air bag. The collar is formed from a single blank of relatively rigid material folded to define three overlying and generally planar panels. Each of the panels defines an aperture therethrough, the apertures being initially aligned in the collar to enable the passage of air therethrough and into the air bag. The middle panel of the collar defines (i) a fixed raceway element adhesively secured to at least one of the outer panels of the collar, and (ii) a detachable slider element secured to the raceway element only by various nicks. The slider element has a first portion defining the aperture of the middle panel and a second portion which is unapertured. When detached from the raceway element by a user breaking the various nicks, the slider element is manually slidably movable (either longitudinally or rotatably) from a first or open position, wherein the aperture of the middle panel is aligned with the apertures of the outer panels, to a second or closed position, wherein the second portion blocks air flow between the apertures of the outer panels.

Abstract: A braking mechanism for avoiding a too sudden release of twist energy stored in a rod string on shut down or power failure, includes a gear pump which incorporates two meshing pinion gears that define a first and a second chamber within the gear pump cavity. A liquid pathway leads from the first chamber to the second chamber and contains flow-restricting means such as a nozzle or valve. The pinion gears are mounted such that pumping takes place only in one direction, namely from the first chamber, through the liquid pathway, and back to the second chamber. Reverse rotation of the pinion gears produces no pumping action due to a relatively large space between the pinion gear teeth and the wall of the cavity, and the relatively close mesh of the two pinion gears with each other. One of the pinion gears is mounted on a shaft which is geared to a portion that rotates with the rod string.

Title: Optical fiber having low loss at 1385 nm and method for making same
Inventor: CHANG KAI HUEI

Filed: 1998-06-10
Granted: 2003-04-29
Abstract: A singlemode optical fiber [700] having very low loss at 1385 nm, and a practical method for making same are disclosed. A core rod [20] is fabricated using vapor axial deposition to have a deposited cladding/core ratio (D/d) that is less than 7.5. The core rod is dehydrated in a chlorine- or fluorine-containing atmosphere at about 1200°C to reduce the amount of OH present to less than 0.8 parts per billion by weight, and then consolidated in a helium atmosphere at about 1500°C to convert the porous soot body into a glass. The consolidated core rod is elongated using an oxygen-hydrogen torch that creates a layer of OH ions on the surface of the rod that are largely removed by plasma etching. Finally, the core rod is installed in a glass tube [40] having a suitably low OH content. Thereafter, the tube is collapsed onto the rod to create a preform [60]. Conventional methods are employed for drawing an optical fiber from the preform and applying one or more protective coatings [75, 76]. The disclosed method is suitable for commercial production of low-OH fiber. Significantly, the fiber's loss at 1385 nm is reduced to a level that is less than its loss at 1310 nm, thereby rendering the entire wavelength region 1200 - 1600 nm suitable for optical transmission. In particular, wave-division-multiplex systems are nowavailable to transmit optical signals over distances greater than 10 km in the wavelength region between 1360 nm and 1430 nm.
