Title: Firing device for discharge lamp
Inventor: KUBOTA SATOSHI
IPC: H02M1/08
Filed: 1981-01-09
Abstract: PURPOSE:To prevent a large current from flowing in a main circuit even in half- wave firing state produced during the period of time while the predetermined period of time after a discharge lamp is started by shortcircuiting the output terminal of a lamp voltage detecting circuit for the predetermined period of time. CONSTITUTION:When a discharge lamp L is started, a voltage is produced across a current limiting inductance CH2. The voltage is applied to the base of a transistor Tr3 via a resistor R18. Thus, the transistor Tr3 is conducted. Accordingly, the output of a lamp voltage detecting circuit becomes zero. The conducting phase angle of an AC controlling element S1 is delayed and fixed to operate to reduce the lamp current. On the other hand, a capacitor C8 is charged via a resistor R20 from the starting time. When the capacitor becomes higher than the prescribed voltage, the transistor Tr3 is interrupted via a diac S4 and a thyristor S3. As a result, the lamp voltage detecting circuit produces a DC voltage corresponding to the lamp voltage. In this manner the lamp current is reduced during the glowing period of time over several seconds after the lamp is started.

Abstract: PURPOSE:To prevent the outflow of mist to the vapor side and to enhance the cleanliness by forming the outlets for the concentrate and vapor at the same place of a duplex cylinder on the downstream side of the circumferential drum of the title evaporator. CONSTITUTION:A raw liq. is supplied from a raw liq. inlet 7, and forms a thin film on the inner surface of a heat-transfer drum 3 by the turning force of a vane 2. The liq. film is scraped by the tip of the vane, agitated, evaporated by the heat from a heating jacket 4, concentrated, moved, and discharged from a product outlet 8, a concentrate outlet 9, and a vapor outlet 11. The concentrate forms a thin film on the inner surface of the drum 3 while the concentrate is subjected to the turning force of the vane 2, however immediately flows down to the concentrate outlet 2 from the product outlet 8 due to a loss of centrifugal force when separated from the region of the vane 2. Meanwhile, the vapor is still rotated due to its small rotation resistance even when separated from the region of the vane 2, moved along the inner surface of the drum 3, separated by an inner cylinder 10, and sent to the vapor outlet 11.

IPC: F02D19/08
Filed: 1990-01-10
Abstract: PURPOSE:To reduce the detection delay to the extent possible by setting the feedback control gain during the present mixing ratio inspection period larger than that during the other period when the fuel supply to a fuel tank is detected. CONSTITUTION:A control unit 40 sets the fuel feed quantity based on the signals of a throttle sensor 48, an air flow sensor 42, and a crank angle sensor 50 and sets the preset feedback gain for the output of an O2 sensor 44 and performs the feedback control of the air-fuel ratio. When the fuel supply to a fuel tank is detected by the signal of a fuel supplying SW, the preset fuel mixing ratio period is determined, the feedback gain during this period is set larger than that during the other period, and the fuel mixing ratio is detected from the magnitude of the average value of the feedback correction quantity based on it. The detection delay is reduced to the extent possible even for the quick change of the fuel status at the time of the fuel supply, and the deterioration of the exhaust gas characteristic due to the detection delay can be prevented.

Abstract: PROBLEM TO BE SOLVED: To automate mairmtenance operations of, e.g. resuming a discharge from a recording head when an ink tank is exchanged, managing the remaining amount of ink, etc., and improve the ease of use. SOLUTION: A carriage 30 is started to be accelerated from a home position(HP). A predetermined number of driving pulses are impressed with a constant pulse rate to a carriage motor when the carriage 30 reaches a predetermined speed. If the carriage 30 is shifted from an HP sensor 8, a passing time is started to be measured, and finished when the predetermined number of pulses are impressed. The obtained time reflects a tracking delay corresponding to a weight of the carriage, that is time is, the time becomes long when there is a lot of ink and short when the amount is decreased. The times are measured and stored beforehand when an ink tank is empty and completely filled with the ink. When ink tanks are exchanged, the times are measured in the same manner and compared with the stored values.  In this manner, whether ink tanks are exchanged or whether the ink tank after being exchanged is full or not can be detected.

Abstract: PURPOSE: To employ so-called 'pull-and-press' driving as a driving system of piezoelectric elements in constitution wherein respective piezoelectric elements are connected in a matrix form by wiring. CONSTITUTION: Respective segment transistors Q11-Q1k are successively turned OFF by the signal inputted from a timing control part 1 and respective data transistors Q21-Q2m are turned ON by the printing data outputted from a printing data output part 2.

Subsequently, when the transistors Q11-Q1k are turned ON and the transistors Q21-Q2m are turned OFF, the applied voltage to the piezoelectric elements is rapidly boosted to the voltage V0 of a power supply 30.  At the time of the rapid boosting of applied voltage, ink droplets are emitted from the nozzles of the piezoelectric elements by the 'pull and press' signal formed by the drop and rapid boosting of the applied voltage to the piezoelectric elements.
