Abstract: PURPOSE:To unify driving ability to drive the loads of voltages of different high pressure power sources by constituting a transistor controlled by the amplitude of a high pressure power source voltage level of plural output transistors and switching the number of concurrently connected output transistors in correspondence to the voltage of the high pressure power source. CONSTITUTION:Complementary transistors come in types Q1 and Q2. The former is controlled by the amplitude of the high pressure power source voltage level and constitutes an output circuit 2. It is composed of plural output transistors Q11, Q12,... which are connected in parallel. The number of them is switched for the high pressure power source voltage so that switch circuits SS1, S2,... can be controlled to impress a high pressure power source voltage HV on a load from an output terminal 3. Where the number of the output transistors Q11, Q12,... connected in such a way increases, the drive ability is raised. If the high pressure power source voltage HV drops to deteriorate the drive ability, switching is controlled so that the number of concurrently connected transistors, increases, thereby unifying the driving ability.

Abstract: PURPOSE:To prevent buckling deformation caused by compressive loads due to differences in temperature and make the opening and closing of a shutter smooth by forming interlocking parts on a main body framework and tonguelike projection at longitudinally intermediate points on shutter-supporting plates and by fitting the tonguelike projections respectively into the interlocking parts. CONSTITUTION:Shutter-supporting plates 13 are attached to a main body framework 6 by fitting tonguelike projections 19 of shuuter-supporting plates 13 respectively into interlocking parts 20 on the main body framework 6 and by fitting raised pieces 17 on the main body framework 6 respectively into cut parts 16 in the shutter- supporting plates 13 at an upper and a lower places on both sides in an interlocking manner. In fitting the tonguelike projections 19 into the interlocking parts 20 in the direction shown by an arrow A, the tonguelike projection 19 undergoes elastic deformation and displacement in the direction shown by an arrow B so that the shuuter- supporting plates 13 are held under pressure from the main body framework 6. Thus the shuuter-supporting plates 13 are placed and held in position by the main body framework 6 and subsequently fixed thereto by screws 14. This method enables easily setting the shutter-supporting plates 13 in position for attachment and preventing buckling deformation of the shutter-supporting plates 13 caused by compressive loads due to differences in temperature.
