Abstract: PURPOSE:To simplify a structure by dispensing with a clutch mechanism, by making it possible to selectively connect a paper feed roller to a platen operating mechanism by the revolving operation of a change-over arm to the direction corresponding to the rotary direction of a platen. CONSTITUTION:When a platen 1 is reversed, a fulcrum gear 15 and a change- over arm 16 revolve to a clockwise direction and an idler gear 18 is meshed with a roller gear 7 to make it possible to allow a paper feed roller 2 to rotate to the clockwise direction. By this mechanism, the slip 33 on a set plate 36 is sent to the contact parts of the platen 1 and pinch rollers 27, 28. At the point of time when a predetermined number of steps are counted, the motor driving the motor gear 10 is stopped. Subsequently, when the platen is rotated positively, the slip 33 is sent toward a printing part 41. At this time, the change- over arm 16 rotates to the counterclockwise direction so as to follow the fulcrum gear 15 to be received by a stopper 39 and, therefore, the idler gear 18 is spaced apart from the roller gear 7. That is, a power blocking state can be provided between a platen operating mechanism and the paper feed roller 2.

IPC: H01L25/07
Filed: 1995-05-15
Abstract: PURPOSE: To suppress restriction due to gel by forming an adhesion retardant layer on a silicon get filling the surface of a chip mounting board thereby retarding adhesion of the gel and a hard resin. CONSTITUTION: A metal substrate 3 in a power module is filled, on the surface thereof, with a silicon gel 8 and the upper surface thereof is filled with one or a plurality of substances 10 selected from a powder, a substance containing fluorine, and a substance containing silicon different from the gel. The upper surface of one or a plurality of substances is further filled with a hard resin 9, e.g. an epoxy resin composition substance. Since an adhesion retardant layer 10 is provided on the interface between the silicon gel 8 and the hard resin 9 filling the surface thereof, the gel 8 does not adhere to the hard resin 9 and restriction due to gel is suppressed. Consequently, structural defect, e.g. a void in the gel, caused by restriction of gel can be suppressed and the moisture resistance of module can be enhanced.

Abstract: PURPOSE:To eliminate automatically offset components of a focus error signal, by modulating a laser light and controlling a differential amplifier by components of the focus error signal which are related to modulation. CONSTITUTION:When photoelectric transducers 5-1-5-4 are different from one another in sensitivity to the quantity of light, output signals S1 and S2 are different from each other by sensitivity. The bias voltage from a DC voltage source 17 is adjusted to set the offset of the focus error signal to 0. In this state, a modulAtion signal S0' is supplied to a laser driving device 1 to modulate the laser light. Modulation signal components in the focus error signal are detected by a modulation signal component detecting circuit 19 and are controlled through a level adjustment driving circuit 20 and etc. in such direction that modulation signal components become zero. Consequently, even if the transmission factor and the reflection factor of a recording carrier 4 are changed, offset components are eliminated automtically.
