Title: Inter-station phase synchronization system
Inventor: NISHIKAWA NOBUHIRO
IPC: H04Q7/36
Filed: 1994-04-18
Abstract: PURPOSE:To enhance the transmission efficiency between a central station and a base station by not providing a timing signal for inter-station phase synchronization to a frame signal from the central station but by providing the timing signal to the base station. CONSTITUTION:A coder 8 of a central station 1 does not provide a timing signal to a frame signal from a radio calling exchange 7 but sends the signal to each base station via a relay line 3 from a line terminator 9. A transmission timing signal adder 14 of the base station 2 adds a transmission timing signal to a tail end of each group of a frame signal from the lie 3 or inserts the transmission timing signal between call signal frames as required. The generated frame signal is sent to a phase synchronization device 11 and the timing signal of the frame signal from an adjacent base station received via a reception antenna 6 and a receiver 13 and a timing signal of the frame signal from the adder 14 are compared in terms of its timing. The difference delay is given to the frame signal from the adder 14 to set the inter-station phase synchronization and the signal si sent from the transmitter 12 via the transmission antenna 5.

Abstract: PURPOSE:To realize highly effective laser oscillation at low threshold value making the most of characteristics of MOCVD process while capacitating for high power output oscillation by stable and basic lateral mode oscillation as well as improving reproducibility and reliability. CONSTITUTION:A current flows from all electrodes widely to a cap layer 20, the second clad layer 19, the third guide layer 18 to be blocked by an insulating layer 15 adjoining to the third guide layer 18 and then flows from a carrier supplying region 17 provided on the insulating layer 15 to the second guide layer 14 adjoining to the third guide layer 18. The carrier flowing from the second guide layer 14 to an active layer 13 is diffused in the level and lateral direction within the active layer 13 forming gain distribution to start laser oscillation. At this time, laser beams are widely diffused from the active layer 13 in the vertical direction due to extremely thin thickness of active layer 13 not exceeding 2-3 times of the wavelength in tube. Especially there are the first and second layers 12, 14 adjoining to the active layer 13 moreover there is the third guide layer 18 adjoining to the second guide layer 14 within the carrier supplying region 17 wherein the total thickness of the second and third guide layers 14, 18 is equivalent to that of the first layer 12. Therefore the laser beams may be widely diffused in the vertical direction centered on the active layer 13.

Abstract: PURPOSE:To form a wiring layer shaped through an electroplating method on the manufacture of an element, which must not be contaminated by a metal, and on the manufacture of a semiconductor element, a ceramic substrate, a printed substrate, etc. to which the electroplating method cannot be applied directly. CONSTITUTION:An aluminum layer 6 is formed on a support substrate 5, and an inter-layer positioning mark is shaped previously to one part of the layer 6. An insulating layer 7 is formed, and a wiring hole section 8 is shaped to the insulating layer 7. Currents are flowed while using the aluminum layer 6 as an electrode in an electroplating liquid of gold to the substrate, and the substrate is plated with gold. The substrate is positioned to an aluminum wiring for an MOS integrated circuit as a foundation substrate, and aluminum and gold 9 are bonded. The connected support substrate and the foundation substrate are put into hot phosphoric acid. Aluminum dissolves in hot phosphoric acid, but gold does not dissolve. The aluminum layer 6 is dissolved by hot phosphoric acid from a side surface 14. Accordingly, a wiring layer constituted by the insulating layer 7 and gold 9 is transferred to the MOS integrated circuit 10 from the support substrate 5. That is, the wiring layer formed by using an electroplating method can be transferred onto the MOS integrated circuit.

Title: Rotary burner device preventive of adhesion of unburnt matter
Inventor: YASUGI MASAAKI
IPC: F23D11/06
Filed: 1985-04-17
Abstract: PURPOSE:To prevent unburnt carbon from adhering over the whole load region of a device and consequently realize the proper combustion by a method wherein adherent unburnt matter is incinerated with a nozzle, to which auxiliary fuel is supplied and which is installed near a portion where unburnt matter is adherently solidified in a rotary cup. CONSTITUTION:An air line 36 and an auxiliary fuel supplying line 37 are to an auxiliary fuel supplying pipe 35. At the starting and during low load of a burner device, suspended carbons tend to adhere around the tip of a cone 3. A controlling device 39 monitors the temperature near a combustion part with a temperature detector 38 at all times. If the monitored temperature lines within the temperature zone, in which the adherent solidification of carbon occurs, the controlling device 39 opens a valve 41 in order to supply auxiliary fuel from nozzles 6. As a result, the temperature near the cone 3 becomes higher than that in the carbon solidification temperature zone and consequently adherent carbon is immediately burnt away and solid deposition of carbon disappears. Further, even if solid deposition of carbon is produced, the deposition can be incinerated by the auxiliary fuel.
