Title: Adjusting system for controlling force in carrier phase correction circuit
Inventor: MURATA HIROYASU
IPC: H04L27/00
Filed: 1986-12-19
Abstract: PURPOSE:To improve an S/N, by constituting a carrier phase correction circuit with a micro time code change detecting means, a corresponding numeric value output means, a time integrating means, and a level adjusting means, detecting the phase jitter of a demodulation wave, and supplying a controlling force corresponding to a detected result to the carrier phase correction circuit. CONSTITUTION:The micro lime change detecting means 1 detects the prescribed change of a demodulation signal wave equalized by an automatic equalizer, etc., with a micro time interval in order. The corresponding numeric value output means 2 outputs a prescribed corresponding numeric value in order corresponding to the detected result of the detecting means 1. The numeric value is time-integrated at every prescribed time by a time integrating means 3, then, an average value is taken, and is sent to the level adjusting means 4. The level adjusting means 4 adjusts the level of an integrated result to a prescribed size, and outputs it to the above stated circuit as the controlling force to be added on the carrier phase correction circuit. Thus, since different kinds of controlling forces are supplied based on not only the existence/non-existence of the phase jitter but the size of the quantity of the phase jitter, it is possible to equalize the phase jitter.

Title: Internal-reforming type fuel cell
Inventor: NISHIYAMA KAI
IPC: H01M8/06
Filed: 1986-12-19
Abstract: PURPOSE:To lengthen the life of a reforming catalyst and a cell by supplying hydrogen produced in a reforming reaction to an electrode and preventing a reforming catalyst from attaching electrolyte evaporated from the electrode side. CONSTITUTION:Raw fuel supplied to a catalyst layer 8 reacts with steam supplied there at the same time to generate hydrogen, carbon monoxide, and carbon dioxide. This reaction is an endothermic reaction. Hydrogen produced permeates a thin film 12 which forms a part of a partition 11 and is supplied to a fuel electrode. Steam and carbon dioxide are produced on a fuel electrode side attendant on cell reaction, and these gasses are exhausted through a gas passage 13 which is formed by the partition 11 and a spacer 5. When reaction gasses are passed as a cell is kept at operating temperature, the electrolyte in an electrode evaporates and is transferred outside by reaction gasses. Although a part of the electrolyte is condensed in a low temperature part in the cell, it does not attached in the catalyst layer 8 where the temperature is lowest in the cell because it is separated by the partition 11 and the thin film 12.

Title: Rotor of squirrel-cage induction motor and manufacture thereof
Inventor: HISAMORI YOICHI
IPC: B23K33/00
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To shorten the brazing time, need no technology, and increase the reliability by replaced brazing by forming recessed or projecting sections on an end face of a rotor bar which is in contact with an end ring along the short side of the end face of the rotor bar to bring the rotor bar into line contact with the end ring. SOLUTION: In an end face of each of a plurality of rotor bars installed in a rotor, recessed or projecting sections are formed along the short side of the end face of the rotor bar and therefore the entire surface of the end face has a small corrugated shape. The rotor bar 1 and the end ring 2 are brought into three-line contact with each other. A groove 8 for brazing formed on the surface of the end ring 2 is formed by lathe machining, and therefore the groove 8 is formed in the entire periphery of the end ring 2. Therefore, after the brazing is finished, fillets are formed on the side face of the rotor bar 1 due to the groove 8 for brazing and stress is not concentrated in one place. As the recessed and projecting sections with a corrugated shape, are formed on the end face of the rotor bar, brazing material permeates into brazing gaps evenly.
