Title: Mineral insulated cable manufacture
Inventor: SIMESTER RONALD A
IPC: G02B6/44
Filed: 1990-02-23
Abstract: ABSTRACT     In a method of manufacturing mineral insulated electric cable in which introduction of mineral insulating powder into, and compaction of the powder in, an advancing metal tube from which the cable sheath is formed can be more rapidly achieved than hitherto, the powder is injected into the metal tube under the pressure of a gas via a powder delivery tube which extends into the metal tube and through which the conductor rods are fed so that the powder fills the space around the rods within the metal tube and is partially compacted under gaseous pressure.  Gas is expelled from the powder delivery tube through filtered outlet ports disposed in the wall of a fitting secured to the downstream end of the delivery tube and effecting a filtered seal with the advancing tube downstream of the ports.  Preferably, the advancing metal tube is disposed horizontally and is continuously formed by bending an advancing ductile strip into tubular form and welding the edges of the advancing strip together.

Title: Control apparatus used for a refrigerant circuit having a compressor with a variable displacement mechanism
IPC: F25B1/02
Filed: 1990-04-17
Abstract: CONTROL APPARATUS USED FOR A REFRIGERANT CIRCUIT HAVING A COMPRESSOR WITH A VARIABLE            DISPLACEMENT MECHANISM          ABSTRACT OF THE DISCLOSURE       An automobile air conditioner system including a refrigerant circuit having a condenser, expansion element, evaporator and wobble plate type compressor with a variable displacement mechanism. Two passages communicate between the crank chamber and the suction chamber in the cylinder block. A bellows is disposed in a first passage and controls the communication between the crank chamber and the suction chamber response to crank chamber pressure. A control valve is disposed in the second passage and controls communication between the crank chamber and the suction chamber in the second passage in response to a signal representing the temperature of the air immedi-ately leaving from the evaporator. An electric clutch is mounted on the compressor in order to intermittently transmit the rotational motion of an automobile engine to the drive shaft of the compressor in response to the signal. The automobile air conditioning system is provided with a demist switch for preventing the reduction of visibil-ity through the windshield of the automobile. The operation of the control valve overrides the operation of the bellows without regard to the temperature signal when the demist switch is turned on.

Abstract: ABSTRACT OF THE DISCLOSURE         In ultrashort optical pulse modulating equipment optical pulses emitted from a laser in synchronism with input electrical signals are modulated by the electrical signals, the modulated optical pulses are applied to a first-stage pulse interval compressor, in which they are alternately distributed, one by one, by an optical switch to two optical fiber delay lines, two modulated optical pulses delayed by the two optical fiber delay lines are brought close to each other, and modulated optical pulse groups, each composed of two closely spaced modulated optical pulses, are output from an optical coupler.  Also in the next-stage pulse interval compressor the modulated optical pulse groups input thereinto are alternately distributed, one by one, by an optical switch to two optical fiber delay lines, in which predetermined delays are caused in the modulated optical pulse groups, respectively, and then they are coupled together by an optical coupler, thereby creating modulated optical pulse groups each composed of four modulated optical pulses. In this way, modulated optical pulse groups are applied to n cascade-connected pulse interval compressors one after another, in which they are brought close to each other two by two and then coupled together, thereby producing modulated optical pulse packets compressed as desired.

Abstract: A magneto-optical disk having a magnetic layer and a conductive layer laminated on a transparent substrate, and having a lubricant layer provided on the conductive layer.          Recording and reproduction on and from the magneto-optical disk are performed by means of a flying head.  The flying head glides above and lands on the lubricant layer.  The magneto-optical disk can therefore be removed from the device easily since a magnetic head does not adhere to a recording medium.  Further, a depressing force exerted on the flying head is controlled so as to maintain a constant floating gap between the flying head and the recording medium.    The   depressing   force   is   controlled   by electrostatic capacity between an electrode, provided on a bottom face of the flying head, and the conductive layer.          Consequently, highly reliable recordings can be made since a magnetic field intensity applied to the magnetic layer becomes constant.   It is  desirable that  the  lubricant layer be composed of an organic binder containing a powder belonging to the ethylene tetrafluoride resin family.

IPC: F21V3/04
Filed: 1991-03-08
Abstract: BIASING SYSTEM FOR REDUCING ION LOSS IN LAMPS            ABSTRACT OF THE DISCLOSURE    A high intensity discharge lamp system includes an AC supply for a chamber within which a plasma conductor is created to generate light.  In order to confine charged particles within the chamber and to inhibit migration and loss thereof, a DC circuit taps power from the AC supply and produces a DC potential which is applied to relatively large-surface components in the vicinity of the plasma chamber.  Properly polarized, the large-surface components, such as a reflector and a conductive housing, refractor or door, produces electric fields which inhibit migration of the charged particles.  The result is improved color and light output as well as increased lamp life.
