Title: Method and apparatus for adjusting of liquid charging amount
Inventor: KAWAMURA TADASHI
IPC: B67C3/04
Filed: 1989-11-21
Abstract: PURPOSE:To simply vary a charging amount by opening a valve, charging liquid in a vessel until liquid surface level in a vent tube becomes the same level as liquid surface level in a tank, and charging remaining liquid from the tube upon closing of the valve to an object amount. CONSTITUTION:A filling valve 18 is moved downward, a valve body 20 is separated from a valve seat 16, a pouring inlet 21 is opened, drink D in a tank 4 is charged in a can C, and the air in the can C is escaped into the tank 4 through a vent tube 19. When the drink D reaches the height of the inlet 21, the drink D intrudes into the tube 19. When the height of the drink D in the tube 19 becomes the same as the height H of the drink D in the tank 4, the valve 18 is raised to close the valve. Then, the liquid D in the tube 19 is dropped, and the liquid of an object amount is charged in the vessel C. Thus, the charging amount in the vessel C can be varied by altering the liquid surface level in the tank 4.

Abstract: PROBLEM TO BE SOLVED: To reduce circuit scale by simplifying the configuration of a unique word detection circuit in a digital communication system employing a π/4 shift QPSK as the modulation system. SOLUTION: A unique word of 2n symbols consists of combinations of two systems of unique words that are respectively sent for one symbol each, the one is mapped at one set of QPSK symbol points having a phase difference of 180 deg. on a constellation of the π/4 shift QPSK and the other is mapped at symbol points in crossing with the one set of the points at an angular difference of 45 deg.. An I phase inner product arithmetic circuit 2 at a receiver side obtains an I phase correlation value CI by dividing past 2n symbols of the I phase component of a received base band signal into two n-symbol series, executing the correlation arithmetic operation with unique words of each system and summing the results.  A correlation value peak detection circuit 12 provides an output of a point when the sum of the I phase correlation value CI and a Q phase correlation value CQ exceeds a threshold level as a unique word timing object.

Abstract: PURPOSE:To improve the efficiency of an inverter load by providing a detection circuit for detecting the continuous time of an ON control signal output from a controlling circuit, and a variable delay circuit for varying the delay time of the signal of a transistor corresponding to the detected continuous time. CONSTITUTION:When a continuous time detected by a detection circuit 3A (3B) is long, a reverse bias voltage between a base and an emitter to be stored in a capacitor 11 (18) of a drive circuit 5A (5B) is sufficiently stored. Even if the delay time is set to a short value, the transistors 12 and 13 of an inverter main circuit 6 are not simultaneously turned ON. On the contrary, when the continuous time is short, the delay time of a variable delay circuit 2B (2A) is set to a long value. In this case, a reverse bias voltage between a base and an emitter to be stored in the capacitor 11 (18) is insufficient, a storage charge discharging time is increased. The delay time of the circuit 2B (2A) is set to a long value so that the transistors 12 and 12 of the circuit 6 may not be simultaneously turned ON.
