Title: Cooling of sheath after extrusion molding
Inventor: NOHARA KOZO
IPC: B29C48/12
Filed: 1985-06-17
Abstract: PURPOSE:To prevent cooling water from scattering and local dents from developing and at the same time enhance cooling efficiency by a method wherein a nearly conical air jet is blasted against a sheathed running body from its whole peripheral direction and further nearly conical water jets are blasted against said running body from its whole peripheral direction on the downstream side of the air jet. CONSTITUTION:On the downstream side of the die 9 of an extruder 7, which extrudes a sheath 4 with a flat cross-section onto a plurality of tubes 2, a nearly conical air jet 17, which has the component of speed in the running direction A of a sheathed running body 11 continuously extruded from the die 9 of the extruder 7, is blasted against the outer peripheral surface of said running body 11 from its whole peripheral direction. Further, nearly conical water jets 18, each of which has the component of speed in the running direction A of the running body 11, are blasted against the running body from its whole peripheral direction on the downstream side of the air jet. Because the cooling water is blasted against the sheathed running body from its whole peripheral direction as described above, cooling is performed highly efficiently. In addition because the bubbles adhered onto the surface of the runner 11 are blasted away, no local dent develops. Further, the cooling water is hard to run in the direction opposite to the running direction of the running body 11.

CONSTITUTION:(S)-Carvone of formula I is sterically selectively reduced to give a secondary alcohol derivative of formula II. The compound is converted to a phthalimide derivative of formula III wherein X is phthaloyl by inversion under a Mitsunobu reaction condition. The phthaloyl group of the compound is removed, carbamoylation and alkylation are successively carried out to give an N,N-disubstituted carbamic acid ester of formula III wherein X is CH2CidenticalCH or CO2Me. The compound is treated with dicobalt octacarbonyl, the prepared complex of formula IV is treated with 4-methylmorpholin-N-oxide and Pauson- Khand ring formation is promoted to give a tricycloenone derivative of formula V. A tricyclocarbamic acid ester (one of formula VI where X=H) is obtained from the compound through a tricycloketone derivative of formula VI and a dithian derivative and reduced to give the objective compound of formula VII.

Title: Method of building up gaas selectively for forming semiconductor laser and semiconductor laser
Inventor: HAINTSU PEETERU MAIYAA
IPC: H01S5/223
Filed: 1989-05-29
Abstract: PURPOSE: To obtain a high performance very small laser of a sub-micron class by selectively growing an active quantum well on a horizontal facet surface of a ridge structure. CONSTITUTION: In a ridge structure 21A, the sidewall facet has a Ga organization speed slower than that of the horizontal facet due to the difference of the crystal orientation. The surface of a substrate 21 is patterned to form the ridge structure on which a semiconductor laser is formed. An AlGaAs bottom clad layer 22 of first conductivity type is grown on all facets of the structure 21A. The thickness of the side wall grows an active GaAs quantum well so that the thickness of the top flat part, which is smaller than the thickness of the sidewall, will be 5 to 10nm. The growth is stopped by stopping the supply of Ga until a thin GaAs layer 23E is completely desorbed from the sidewall facet. An AlGaAs top clad layer 24 of second conductivity type is grown on all facets. Thus, a high performance small laser can be obtained.

Title: Transmissive photoelectric switch
Inventor: WATANABE YASUYUKI
IPC: H03K17/78
Filed: 1978-10-30
Abstract: PURPOSE: To enhance the peak value of the projected light and then to simplify the structure of the photoelectric switch by giving the pulse driving to the light emitting diode of the projector synchronizing with the AC power source more than once with every 1/2 cycle of the AC power source.  
     CONSTITUTION: Voltage-division resistances 18 and 19, capacitor 21 and constant voltage diode 20 are connected in parallel to SCR24 of projector 1, and SCR24 conducts at the specific phase time and with every 1/2 cycle of the AC power voltage received the full-wave rectification. Light emitting diode 22 is driven by the discharge pulse of capacitor 21, and the peak value of the projected light of diode 22 increases. When this projected light is received at photo detector 41 of receiver 3, SCR61 of cut-off circuit 6 conducts. And trigger circuit 7, which generates the trigger pulse synchronizing with the fixed phase of the AC power voltage, is stopped with no excitation given to relay 82. Relay 82 is excited by the light projector and the light receiver which feature the syncgronous action only when the light is cut off by test subject 2. Owing to this projected light featuring a large peak value, no high amplification is required for the light reception signal, thus simplifying the structure of the photoelectric switch.
