Title: Method and apparatus for loop synchronization in spectrum scattering loop transmission system
Inventor: HIROSAKI BOUTAROU
IPC: H04L12/42
Filed: 1980-11-21
Abstract: PURPOSE:To improve the loop synchronization in an SS loop transmission system which receives and transmits a desired signal, by using a spectrum scattering (SS) modulation/demodulation method for a plurality of subscriber terminals dotted on a loop transmission line. CONSTITUTION:Before the start of data transmission/reception between subscriber terminals 12-18, first a virtual noise series having predetermined frame period as a synchronizing signal from a synchronizing terminal 11 is transmitted to a loop transmission line 10. The terminal 11 detects the frame phase defference between the transmitted virtual noise series and that returned through circulation, and the loop synchronization can be established by controlling the phase of a virtual noise generating clock so that the frame phase difference is zero. After subscriber terminals 12-18 are elapsed for the time for loop synchronization a signal inputted from the loop transmission line 10 detects the synchronous virtual noise series and discriminates the frame reference time, generates the SS modulation/demodulation virtual noise series in frame synchronization and this is used as SS modulation/demodulation carrier.

Abstract: PURPOSE:To obtain the output without distortion, by removing the amplitude variance of the output voltage, through the setting of the output impedance of the power supply connected to the output terminal via a diode sufficiently lower than the current flowing to the diode. CONSTITUTION:The 3rd and 4th transistors Q3, Q4 operated as an emitter follower circuit are provided at the 3rd and 4th power supplies 3, 4, to enable sufficient current flowing.

Thus, the saturation voltage of the diodes D3, D4 is changed almost the same as the temperature change in the voltage of the sum between voltages Vbe and Vf, allowing to compensate the level variance of amplitude due to the temperature change.

Title: Catalytic combustor
Inventor: MATSUMOTO TOSHINARI
IPC: B01J23/42
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To downsize a catalytic combustor body by providing a burner port, constituted of a catalytic net, at the boundary of a mixing section and an igniting section so that catalytic combustion can take place. SOLUTION: Since a catalytic net 25a has a small opening area, current velocity of combustible gas passing through the opening is increased and a flame is formed closely to a combustion catalyst 22 remote from a burner port 25. Consequently, the combustion catalyst 22 reaches a catalytic combustion temperature within several seconds. Since the catalytic net 25a has a small thermal capacity, temperature thereof rises instantaneously even if a flame is formed remotely to start catalytic combustion. Consequently, a flame formed at the burner port 25 extinguishes naturally and catalytic combustion also takes place at the combustion catalyst 22. Since a mixing section 18 is a straight tubular passage, a combustor 11 can be made thick and since the catalytic net 25a is used as the burner port 25, opening area can be decreased.  Consequently, current velocity of combustible gas passing through the opening can be increased and a flame can be formed closely to the combustion catalyst 22. Catalytic combustion can thereby be executed surely while reducing the size.

Abstract: PURPOSE:To solve the deterioration in the production yield of the production of a device due to a resist residue, and to remove completely a resist by providing with a step of acting an unexposed photoresist layer with a reducing agent solution before a step of processing said layer with a peeling solution. CONSTITUTION:A resist film 2 is mounted on a substrate 1, and then, a positive resist layer 3 is formed on said resist film. The exposed positive resist layer is dissolved, and then, the exposed chrome film is removed with an etchant contg. a cerium (IV) compd. In this case, a modified layer, namely the insolubled resist 4 is again changed to a soluble structure by reacting said resist 4 with a reducing agent, thereby easily dissolving said resist 4 with a specified peeling solution. The method for processing said resist with the reducing agent, lies in dipping the substrate 1 into a solution 5 contg. the reducing agent. Next, the obtd. substrate is processed with the specified peeling solution for the positive type resist. Thus, as the resist 4 is completely removed from the substrate 1, the production yield in the production of the device is improved.
