Inventor: TAGUCHI MASAKAZU
IPC: G11B20/10
Filed: 1992-03-17
Granted: 1996-01-02
Abstract: A read out apparatus reads out prerecorded information from a magneto-optic disk by detecting intervals of edges of magnetic domains formed on the magneto-optic disk with different directions of magnetization, where the intervals of the edges of the magnetic domains correspond to data "1"s or "0"s of the prerecorded information.  The read out apparatus includes a first part for producing a read out signal by scanning the magnetic domains of the magneto-optic disk, a second part for producing an edge detection signal which has rising and falling edges depending on leading and trailing edges of the magnetic domains, and for correcting edge positions of the edge detection signal based on predetermined information, a third part including a phase locked loop circuit for producing a clock signal which is synchronized to the rising and falling edges of the edge detection signal, and a fourth part for separating the data from the edge detection signal output from the second part using the clock signal output from the third part.

Title: Continuous flow heater for an apparatus for making infusion beverages
Inventor: SCHIEBELHUTH HEINZ
IPC: A47J31/047
Filed: 1992-04-23
Granted: 1994-11-22
Abstract: In the electrically heated continuous flow heater another electric switching element (26) having an open and a closed switching position is electrically connected in series to the thermostat (12), it being always closed in the brewing process while it can be opened and closed again in the keep-warm process by a control circuit (11).  Said control circuit (11) comprises a temperature sensor (21) which is in good heat contact with the infusion beverage.  When in the initial phase of the keep-warm process the sensor temperature is in excess of a definable switching temperature, the control circuit (11) keeps the switching element (26) in its open position for as long as the sensor temperature remains higher than the switching temperature in the course of the consequently occurring cooling of the infusion beverage.  When the sensor temperature is below or equal to the temperature of the switching element (26) in the keep-warm process, the control circuit (11) keeps the switching element (26) in its closed position for a prede-finable first time interval (heating cycle) irrespective of the sensor temperatures produced during the heating cycle.  The heating cycle is rated to be so short that the temperature of the thermostat (12) always remains below said's opening tem-perature.  Upon termination of the heating cycle, the control circuit (11) opens the switching element (26) irrespective of the temperature measured by the temperature sensor (21) at the end of the cycle and keeps it open for a definable dead time. It is accomplished thereby that, on the one hand, the continu-ous flow heater (1) furnishes its full heating power in the brewing process, and that, on the other hand, this power is controlled in the keep-warm process such that the temperature variations of the warming plate (10) and hence those of the infusion beverage are minimized to the greatest possible extent.

Title: Method for manufacture of high purity carbon monoxide
Inventor: FISHER DANIEL E
IPC: C01B32/40
Filed: 1992-02-27
Granted: 1996-10-15
Abstract: The present invention is directed to a method for producing high purity carbon monoxide. In the method, a hydrocarbon feed stock and import carbon dioxide are introduced into a reaction system containing a primary reformer and a secondary re-former. The hydrocarbon feed stock, import carbon monoxide and recycle carbon monoxide are passed through the primary re-former while being heated to a temperature sufficient to reform the feed stock into a first carbon monoxide reaction product. The first reaction product and oxygen are fed into the secondary reformer. The first reaction product is reacted in the secondary re-former in an autothermal reation to provide a second carbon monoxide reaction product having a lower hydrocarbon level than the first reaction product. The second reaction product is removed from the secondary reformer at a second predetermined tem-perature and a high purity carbon monoxide is recovered from the second reaction product without the use of cryogenic separa-tion techniques.

Abstract: A transmission power control method of a mobile station in a CDMA (Code Division Multiple Access) system which primarily controls transmission power of the mobile station by using a closed loop control which enables high accuracy power control.          When the received power at the base station of a signal from the mobile station suddenly increases owing to the state of buildings surrounding the mobile station, the transmission power of the mobile station must be quickly reduced to prevent the interference to other mobile stations.  The mobile station measures an average value of the received power per transmission power control period of a desired signal from the base station, and detects the difference .DELTA.RSSI between the current average value and that of one of the previous transmission power control periods.  If .DELTA.RSSI exceeds a reference power difference .DELTA.Pth, transmission power PT corresponding to .DELTA.RSSI is set by using an open loop transmission power control to quickly reduce the transmission power of the mobile station.  If .DELTA.RSSI is lower than .DELTA.Pth, the transmission power PT is determined in accordance with the transmission power control bit sent from the base station.
