Title: Process and apparatus for working astringer,in particular the vicinity of the bottom end therer
Inventor: TAGANO SHINJI
IPC: A44B19/60
Filed: 1982-05-04
Granted: 1984-09-24
Abstract: A stringer comprises a tape with a row of continuous coupling elements of thermoplastics mounted along one edge.  An end element has a cut end turn remote from the tape edge and the tape has an element-free region adjacent to the end element, with the end element upper leg lower than the upper legs of other elements.  The row pref. has a reinforcing core secured to the tape by sewing threads running across and over element upper legs.  The cut end turn is fused to the tape while the upper leg of the end element is pressed under heat towards the tape and is displaced to tilt down towards the cut turn.  A stop may be attached to the free region of the tape under pressre so that it sandwiches the tape.

Filed: 1983-12-10
Granted: 1986-02-19
Abstract: The auto-tuning circuit provides a stable tuning state in TV electronic tuning circuits and selects channels with up-and-down selecting switchs. The signal comparator(Q3) produces a status signal from the synchronization pulse(3) and the fly-back pulse(4). The up- and-down channel control signals and the status signals, which are generated by the signal comparator, are kept in the flip-flop circuits(Q1). The signal control circuits(Q3) and the memory circuits(Q2), which contain the condition of the AFC(6) voltage, generate tuning control voltage(2) for the tuning channels.

Title: Method for converting a rotary motion into an oscillatory motion by way of intermittant motion gear
Inventor: HAN SUN-YUN
IPC: F16H1/00
Filed: 1984-10-24
Granted: 1987-01-28
Abstract: A canstant direction rotating power is output at the jointed gears using more than three intermittent motion gears when rotary power is input into one or one pair of gears. Bevel gears drive when the direction of the input and output shafts forms a right angle. A spur gear drives when the direction is the same. One pair of  normal spur gears is needed when the spur gear is used for motion transmission. Rachet spring clutch coupling, brake, and a plate cam are used for precise jointing of the output gear. Over riding clutch or fly-wheel clutch makes the rotating power a constant speed motion.

Title: Light stabilized starshaped microparticles
Inventor: MARIO SLONGO
IPC: C08F293/00
Filed: 1988-06-04
Granted: 1996-01-24
Abstract: Light-stabilized star polymer microparticles are described which are prepared with particular advantage by group transfer polymerization. The light stabilization is effected by carrying out at least a part step of the polymerization in the presence of a light stabilizer, for example a hindered amine or/and a UV absorber. With particular advantage, those light stabilizers are used which contain reactive groups in the molecule and, in this way, can be chemically incorporated into the polymer. The polymer microparticles show excellent light stability and are outstandingly suitable as constituents in coating compositions which can be processed, for example, to give coating films of high light stability.

Abstract: forming an ion implantation area for forming a low-concentration second conductive type first and third areas; forming an ion implantation area for forming the high concentration second conductive type fourth and sixth areas and a high concentration first conductive type fifth area between the fourth and sixth areas; forming the first and sixth areas by activating the impurity material of the areas; forming an epitaxial layer on the substrate; forming a low concentration second conductive type ion implantation area on the first and third epitaxial layer; forming the low concentration second conductive type ion implantation area on the fourth and sixth epitaxial areas; forming the low concentration second conductive type ion implantation area on the third and fifth epitaxial areas; and forming an ion implantation area to form an emitter/base area of a high/low voltage bipolar transistor; and activating the ion implation area and forming the electrode.
