Title: Tape driving mechanism
Inventor: MITSUYASU TAMOTSU
IPC: G11B15/60
Filed: 1988-06-15
Abstract: PURPOSE:To attain the stable drive of a tape and to prevent the damage of the tape edge part by tilting a post via an actuator with the detecting output of a sensor which detects the up-down movements of the tape and controlling the up-down positions of the tape. CONSTITUTION:A tape 3 rubs the outer circumferential surface of a post 1. A piezoelectric element 2 warps when it receives the DC voltage. As a result, the post 1 fixed at a single end part 2a is tilted. In case the tape 3 moves up and down from its prescribed reference position, a sensor detects the shift extent of the tape 3. Then the element 2 is curved in response to the detecting output of the sensor. Thus the post 1 is tilted in an optional direction at an optional angle. Then the tape 3 is moved up and down and the up-down position of the tape 3 is controlled.

Abstract: PURPOSE: To facilitate the recognition on the surface of semiconductor chips by selecting the energy of light irradiated at a level smaller than the bandgap of the chips and prescribing the angle of incidence and the chip size when the image on the surface is recognized by the radiation of light.  
     CONSTITUTION: A semiconductor chip 1 including an Al electrode 3 is placed on a lead frame 2 with the electrode upward, and then, light is irradiated thereon slantly from above to recognize the electrode 3. At this point, the energy of the light is selected at a level smaller than the bandgap of the material composing the chip 1. Thus, the light is reflected directly on the electrode 3 while it goes out through the surface of the chip 1 after entering the bottom face. In addition, the chip size must meet the equation I, where the thickness of the chip is d, the length a thereof in the direction of incidence and the refractory ratio n 2 . The angle of incidence also satisfies the value as given by the equation II. With such an arrangement, the reflected light from the electrode 3 can be distinctly discriminated thereby facilitating the recognition.

Abstract: PURPOSE:To reduce the time for warming up and to eliminate staining on the rear side, by using a fixation device having a roll of thin mandrel, and performing thermal fixation by using a toner of the elasticity increasing with time at the fixing temp. thereof. CONSTITUTION:A fixation device 100 is formed of a heat roll 1 wherein a film 12 of a ''Teflon'' resin or the like is formed on the outside circumference of a mandrel 11 consisting of a cylindrical metal and a press contact roll 3 which is in press contact with the heat roll and wherein a film 32 of a silicone resin is formed on the outside circumferential surface of a mandrel 31.

Filed: 1984-07-18
Abstract: PURPOSE:To accomplish a stable action under a low voltage power source without adversely affecting a high speed of a current mirror-type circuit by providing a reverse conductive FET connected to the power source of a common node at one side of an FET controlled by means of a differential input, and controlling the output at the other side. CONSTITUTION:When a differential input Vin and its anti-Vin drops and rises, respectively, FETs Q13 and Q14 start turning on and off, respectively. An output Vout and its anti-Vout are connected to power sources VDD, and changed to be ''L'' and ''H'' through Q16 and Q17 for comprising a current mirror circuit, respectively. Then, after a common node at one side of the Q13 and Q14 is controlled by the output Vout, it is connected to the power source VDD, and the Q13, Q14 and a reverse conductive Q18 are turned on. Thus the common node at one end of the Q13 and Q14 goes to a voltage near to the power source VDD to turn off completely the Q13, and the output anti-Vout goes to a completely high level. Accordingly a stable action is made possible under a low power source voltage without adversely affecting a high speed of a current mirror-type sensor circuit.
