Title: Discharge lamp lighting device and illuminating equipment
Inventor: OTA MASAAKI
IPC: H02M7/537
Filed: 1991-09-24
Abstract: PURPOSE:To provide a discharge lamp lighting device capable of lighting up a discharge lamp accurately even if the lamp is restarted immediately after an electric power supply is turned on. CONSTITUTION:When a discharge lamp is started, trigger is generated by means of a trigger circuit 12. Electric charge of a capacitor C9 in a time constant circuit 15 is reset by means of this trigger. During the first prescribed time when voltage of the capacitor C9 rises up to the first prescribed voltage, the time constant circuit 15 carries out soft start by lowering voltage induced by means of an auto-transformer Tr1. During the second prescribed time after the lamp is started when the voltage of the capacitor C9 rises up to the second prescribed voltage, an electric current is not supplied to a base of a transistor Tr3, and even if a dimming signal is inputted, dimming lighting is not carried out. Even if the lamp is restarted immediately after an electric power supply is turned off, since the trigger is generated by means of the trigger circuit 12 and the electric charge of the capacitor C9 is reset, even if the lamp is restarted immediately, operation can be carried out in the same way as usual.

Title: Manufacture of heat exchanger
Inventor: KOMA HACHIRO
IPC: B23K1/00
Filed: 1989-09-20
Abstract: PURPOSE:To secure the stable joining and to obtain the heat exchanger with high performance by inserting the two heat transfer tubes of about triangle state into the approximately lozenge-shaped heat transfer tube insert hole which is set on the fin, enlarging the distance of the above heat transfer tubes and brazing in the state of no gap between the fin and the heat transfer tube. CONSTITUTION:Air flow upstream side and downstream side heat transfer tubes 4, 5 are inserted into the approximately lozenged - shaped heat transfer tube insert hole which is set on the plane fin 2. Because the sum of width of both heat transfer tubes is smaller than the length of the longitudinal direction of the insert hole 3, so the inserting is easily executed without damaging the fin 2. Next by enlarging the distance of both heat transfer tubes 4, 5, the heat transfer tubes 4, 5 are brought respectively into contact with two side of the up and down stream direction sides of gas flow of the insert hole 3. The brazing material clad to one or both surfaces of the fin 2 is brought to flow in their contact surface and joint the both with the brazing in the furnace. Therefore, the brazing is completely and stably executed.

Filed: 1984-11-19
Abstract: PURPOSE:To attain accurate reading by generating a pulse in response to the movement of an image sensor, frequency-dividing the pulse and using a frequency-division output pulse so as to control the reading of the image sensor. CONSTITUTION:In the scanning system by an image sensor, an encoder pulse of a motor encoder is frequency-divided into 1/n by a fixed frequency divider 71a of a frequency divider circuit 71.
