Patent JP-H0567927-A (JP)
Title: Amplifier circuit
Inventor: YAGI NAOSHI
IPC: H03F3/187
Filed: 1991-09-06
Abstract: PURPOSE:To improve the efficiency by reducing a loss of an output stage element due to an idle current in the amplifier circuit of class A operation. CONSTITUTION:An input signal is converted into a current by a voltage-current conversion circuit 8. The current is inputted to a current/current conversion circuit 3. The circuit 3 consists of four transistors(TRs) 1-4. The TRs 1,2 act like class A amplifiers (non-cut-off) and output currents I1, I2 in response to the input. The currents I1, I2 are converted into voltages respectively by resistors r1, r2 via current mirror circuits 6,7, amplified by output stage TRs Qa, Qa' to drive a load 10. Power is supplied mainly from a main power supply line 42 in switching drive. Since the main power supply path 42 keeps a voltage VQa of the TRs Qa, Qa' to a minimum value, even when the idle current is large, the loss in the TRs Qa, Qa' is reduced. The leading delay by a smoothing coil L1 is compensated by an auxiliary power supply line 48.

Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To minimize the residual quantity of toner after supplement and prevent the change of charging property by using polyolefin as the resin constituting a toner supplying vessel body, and containing calcium carbonate or antimony trioxide therein. SOLUTION: A vessel body 1 has a cylindrical form opened in one end, which is formed of a polyolefin resin such as polyethylene, polypropylene and the like. Fine particles of antimony trioxide or calcium carbonate are added to the resin. The fine particles have number average particle sizes of 0.01μm-1.0mm, preferably, 0.001-0.5mm. The addition quantity of the fine particles is 0.1-50wt.% to the resin, preferably, 0.5-20wt.%.

Abstract: PURPOSE:To stabilize an exial mode by making layer thickness on the channel outside of a clad layer close by the substrate side more than an active layer different from others only in a specific region along a waveguide and making a lateral effective refractive index difference in the region different from others. CONSTITUTION:A clad layer 2, an active layer 3, a clad layer 4 and a cap layer 5 are grown on a surface with a channel groove in a substrate 1 in an epitaxial manner in succession, thus forming double hetero-junction type laser operating multilayer crystal structure. The layer thickness of the clad layer 2 on the channel outside 9 is made thicker than a corresponding section 7 in a region as an internal reflection section. Beams propagated in a waveguide on the channel inside sense the change of an effective refractive index in B-B' region, and one part thereof is reflected in the B-B' region. Accordingly, the effective internal reflection section is constituted by giving distribution to a distance between the active layer and the substrate through a means such as the formation of longitudinal and lateral grooves of two kinds to the substrate, thus realizing the stability of an excellent axial mode by a simple interference type laser.
