Title: Optical writing head
Inventor: OKI TOSHIHIKO
IPC: G02B26/10
Filed: 1987-08-21
Abstract: PURPOSE:To obtain a small-sized optical writing device by providing such an optical system that the distance from a polygon mirror to the surface of a photosensitive body is constant. CONSTITUTION:A sign A indicates the path on a laser light surface to be swept from the polygon mirror 3 to a 1st reflecting plate 5, a sign B the path from the 1st reflecting plate 5 to a 2nd reflecting plate 6, and a sign C the path from the 2nd reflecting plate 6 to the photosensitive drum 8 through a 3rd reflecting plate 7. Here, the distance from a semiconductor laser 1 to the surface of the photosensitive drum 8 can be made constant by shaping the 1st reflecting plate 5 and 2nd reflecting plate 6 so that A+B+C=An+Bn+Cn. Thus, the need for an f-theta lens and a special shape polygon mirror is eliminated by making the distance of laser light from the semiconductor laser 1 to the surface of the photosensitive body drum 8 constant by employing a combination of a plane and a curved surface for the optical system, thereby reducing the size of the optical system.

Abstract: PURPOSE:To obtain stable flame electric current of flame rod by a method wherein a flow restricting fitment is provided at the side of vaporizing cylinder of a burner head at a part opposing to the flame rod, in the combustion device effecting pre-mixing combustion employed for kerosine fan heater or the like. CONSTITUTION:The flow restricting fitment 18 is provided at a position opposing to the tip end 17a of the flame rod 17, therefore, mixed gas, ejected from flame ports 16 at this part, is stagnated in a gap formed between the flow restricting fitment 18 and the flame ports 16 or wire net 15. Accordingly, the flow speed of the mixed gas ejected from this part is lower than the same gas ejected from the flame ports 16 at the other parts. As a result, flame 21 at the position opposing to the flame rod 17 is contacted closely with the flame ports 16 compared with the flames 21 of the other parts, therefore, stable flame electric current may be obtained even if the balance of air-fuel ratio is unbalanced to some degree.

Title: Mosfet driving circuit
Inventor: OTSU SATOSHI
IPC: H03K17/687
Filed: 1989-08-11
Abstract: PURPOSE:To suppress the increase of loss due to reduction of the threshold voltage of a MOSFET with a simple circuit constitution by providing a circuit, which shifts the DC component of a driving signal voltage, between the MOSFET to be driven and a driving circuit. CONSTITUTION:MOSFETs 2 and 3 take the input from a driving signal source 4 to generate the driving signal voltage which controls the turning-on period and the turning-off period between a drain C and the source of a MOSFET 1 to be driven. A capacitor 7 is connected between a connection point D of drains of MOSFETs 2 and 3 and a gate B of the MOSFET 1 to be driven, and a resistance 8 is connected between the point B and the ground. Consequently, the DC component of the driving signal voltage is shifted by the capacitor 7 and the resistance 8, and a negative voltage is impressed between the gate and the source in the turn-off period of the MOSFET 1 to be driven. Thus, a simple circuit is only connected to suppress not only the increase of the drain current in the turning-off period accompanied with the reduction of the threshold due to the degradation of the MOSFET to be driven but also the reduction of the noise margin.
