Abstract: PURPOSE:To rapidly set a detection optimum threshold voltage of a horizontal synchronizing signal to a PLL circuit by storing the combination of a threshold voltage and a phase comparator output signal with a prescribed detection width or below so as to extract the threshold voltage in which the phase comparator output signal has a minimum width. CONSTITUTION:A phase difference output of a phase comparator of a PLL circuit 10 generating a sampling clock of an inputted picture signal is branched, the one signal is delayed through a programmable delay line 21 by a prescribed time (t) and the signal and the delayed signal are inputted to an AND circuit 20. When the delay time (t) is set very small, an output from the AND circuit 20 is easily obtained, With a threshold level set constant, when the delay time (t) is changed, a point where no output is in existence in the AND circuit 20 in the PLL lock state is sequentially detected. The relation of the both obtained by changing the setting of the threshold level and detecting it similarly is stored in a data memory 3 and the optimum threshold level to fetch a picture data in an excellent way is obtained by selecting the threshold level to obtain the point for the longest delay time (t) without absence of an output from the AND circuit 20.

IPC: H01L21/3205
Filed: 1980-05-29
Abstract: PURPOSE:To improve the quality of a semiconductor device and to reduce the cost thereof by interposing a Ti-W alloy layer in the intermediate of an electrode layer formed of aluminum or its alloy. CONSTITUTION:A Ti-W layer 10 and an aluminum layer 11 are superposed on a Ti-Al layer 9. The layer 9 is made of AlTi3 of approx. 1,500Angstrom  thick, the layer 10 has a thickness of approx. 1,500Angstrom  and approx. 10-20% of Ti content, and the layer 11 has a thickness of approx. 1mum. Since the Ti-W layer serves to prevent the elute of Si at the heat treating time in the three-layer structure, a wiring resistance does not increase. Even if small amount of P type Si layer is formed in the boundary with the Si substrate when the Ti-Al layer is formed thinly, a complete P-N junction is not formed between the electrode layer and the substrate with the result that the contact resistance becomes low. Since the layer is further stable intermetallic compound, the elute of the Si is further small amount. Thus, the characteristics of the element can be selected by the metal of the alloy layer 9, the element has stability and preferred adherence with the SiO2 film of the electrode with low resistance.

On the other hand, when the magnetic toner 4 is used, the toner 4 on the transfer means 1 is transferred on the side of the image carrier 2 by the magnet 6a or the electromagnet, opposite to the transfer means 1 via the image carrier 2, to clean the transfer means 1.

Abstract: PROBLEM TO BE SOLVED: To obtain a pointing device and a mouse device capable of realizing control corresponding to the intention of an operator. SOLUTION: When a wrist does not touch the detection surface of an electrostatic sensor 15, that is, when an operator operates a mouse with the entire hand while floating the wrist in the air, a fast mode is set because the operator has intention of moving a cursor position on a display 12 relatively largely. When the wrist is brought into contact with the detection surface (operation reference surface) of the sensor 15, whether or not the wrist moves is further decided. In the case the wrist does not move, i.e., when the operator almost fixes the wrist and operates the mouse with fingertips alone, a slow mode is set because the operator has intention of wanting to perform relatively small movement of the cursor position on the display 12. In the case the wrist moves, i.e., when the operator performs slide movement of the entire hand, a medium speed mode is set.

IPC: H02P7/288
Filed: 1985-04-05
Abstract: PURPOSE:To prevent a motor from unnaturally rising the rotation occurred at a voltage drop time by suppressing a reference current in response to the reference voltage. CONSTITUTION:The induced electromotive force of a motor 2 is compared by a comparator 20 with a reference voltage Vref set by a reference voltage source 16, and the comparator 20 applies the control output in response to the error to the base of a current controlling transistor 8. A current limiter 26 limits a current simultraneously when a drive transistor 4 is saturated by utilizing that the collector potential of the transistor 4 and the negative side terminal of the source 16 are equal. When thus constructed, the displacement of the ratio of the current flowed to the transistor 4 due to the saturation of the transistor 4 to that of a transistor 6 is suppressed to prevent the rotating speed of the motor 2 from increasing at a voltage drop time.
