Title: Ink jet recorder equipped with blasting means
Inventor: EBISAWA ISAO
IPC: B41J2/01
Filed: 1990-03-24
Abstract: PURPOSE:To remove ink mist certainly and to prevent dew also from condensing by a method wherein a flow velocity of gas to be formed in a recording clearance between a recording means and a recording area is made slower than a velocity of an ink drop to be formed by a recording means. CONSTITUTION:A slit 91 (a blasting part permissible part) is so formed to a carriage 2 that a blast opening forming an air flow hitting against a lower part of a recording head 1 in two trained blast openings 9 can be made always open. The air having passed through this slit 91 forms a weak gas flow (a flow which hits on the lower part of the head at slow speed than an ink drop discharge speed of 8m/sec from an ink discharging surface to decrease its speed and of which a speed becomes 1m/sec thereafter) to a recording clearance while the carriage 2 is being moved and is stopped also. When the blasting part permissible part (a slit 92) of the carriage 92 is provided to a blasting opening 9 for forming an air flow to be blasted directly to the recording clearance and the recording clearance is made to be 1mm or under, the velocity of gas should preferably be 5cm/sec or over up to and including 2m/sec.

Title: Ttl-ecl level conversion circuit
Inventor: UMEKI YOSHITAKA
IPC: H03K19/018
Filed: 1989-03-27
Abstract: PURPOSE:To attain the stable operation of an ECL circuit even when a TTL level changes slowly by providing a hysteresis characteristic to a TTL level input circuit and providing a proper input voltage to an ECL circuit, thereby shaping the input waveform of the TTL level. CONSTITUTION:When an L level voltage is applied to a TTL level input terminal 11, the level of an ECL input terminal 13 goes to -0.8V and a level at an ECL output terminal 12 goes to an L level. When a TTL level input voltage is boasted gradually and the level reaches a high threshold level, transistors(TRs) Q11, Q12 are turned on and then the base level of TRs Q13, Q14 is lowered and the TRs are conductive. Then the current of the TRs Q12-Q14 is increased rapidly by the positive feedback action of the TRs Q12, Q13. When an emitter-collector voltage of the TR Q13 is lowered more than the base-emitter voltage of a TR Q11, the TR Q11 is turned off. On the other hand, since the TR Q14 is conductive at the same time, the level at the terminal 13 rises up to 0V via a diode D14 and the level of the output terminal 12 is changed to an H level.

Filed: 1978-06-21
Abstract: PURPOSE: To let shutter closing characteristics become sharp, obtain highly accurate shutter speeds and reduce the power consumption of power source batteries by supplying the driving current at the shutter closing from the boosted and charged capacitor.  
     CONSTITUTION: When the main switch MSW of the camera is closed in an electromagnetically driven shutter device which is electromagnetically opened and closed by an electromagnetic driving device, a DC booster 55 operates and a capacitor 62 is subsequently charged by the output voltage thereof. When the shutter is released in this state, a switch SW 1 closes to start charging to a time-setting capacitor 45 and supply current to the coil 9 of a motor from a battery 40 through switching transistors TR 8 and TR 5, whereby shutter opening is accomplished. At the closing of the shutter, large current flows from the capacitor 62 to the coil 9 of the motor through switching transistors TR 6 and TR7, thus the shutter closes rapidly.

Abstract: PURPOSE:To perform feedforward (FF) control without using any flow rate sensor, by maintaining a constant heating value at the time of starting supply of hot water, calculating the gradient of hot water temperature with time while the constant heating value is maintained, estimating the quantity of hot water supplied on the basis of the gradient, correcting the estimated quantity to a small quantity, and outputting the corrected quantity to an FF part. CONSTITUTION:A hot water temperature controller 11 comprises a water temperature sensor 1, a hot water temperature sensor 4, a setting part 5 and a heating value controlling part 12. The controlling part 12 comprises a feedback (FB) part 8, an FF part 9, an adding part 10, a heating value holding part 13 for holding the heating value at a constant level at the time of starting supply of hot water, a gradient calculating part 14 for calculating the gradient of hot water temperature with time, a flow rate estimating part 15 for estimating the quantity of hot water supplied on the basis of the gradient and outputting a cancel signal to the heating value holding part 13 when the estimation is finished, and a correcting part 16 for outputting to the FF part 9 an estimated flow rate obtained by multiplying the estimated quantity of hot water supplied by a predetermined value less than 1. The FF part 9 calculates a predetermined heating value from the estimated flow rate, feed water temperature and a set hot water temperature, and the predetermined heating value thus calculated is added to an output from the FB part by the adding part 10. When being supplied with the cancel signal from the flow rate estimating part 15, the heating value holding part 13 stops holding the constant heating value, and a heating part 3 is thereafter controlled by an output from the adding part 10.
