Title: Aligner
Inventor: HASEGAWA TAKAYUKI
IPC: H01L21/027
Filed: 1990-05-10
Abstract: PURPOSE:To improve a through put by installing a window to cut off first light and pass second light through in a shading device of an aligner which positions a mask and a wafer by casting the first light on the wafer through the mask and the second light on alignment marks of the mask and the wafer. CONSTITUTION:In such a condition that the deviation in positions of a mask 1 and a wafer 2 is detected, an aperture blade 4 is positioned back from an alignment mark 101 in order not to stand in the way of laser beam 601 to the alignment mark 101. After the alignment of the wafer 2 and the mask 1 is done on a signal to tell the deviation in positions, the aperture blade 4 moves to the position to cut off the laser beam 601. When the exposure is conducted, the aperture blade 4 moves on to shield the alignment mark 101, but not a circuit pattern section 102, from X-rays for exposure 7. The laser beam 601, passing through a window 401 of the aperture blade 4, reaches the alignment mark 101. Owing to this system, the positioning of the mask and the wafer can be done even at the time of such an exposure in which an exposure area is restricted, with the result of the improvement of a throughput.

Title: Motor driven vehicle
Inventor: KAMIYA YUTAKA
IPC: A61G5/04
Filed: 1982-07-08
Abstract: PURPOSE:To prevent the abrupt starting of a motor driven vehicle by providing a neutral correcting circuit which sets a command speed signal to zero in the prescribed width in the vicinity of the neutral point of a speed instructing unit. CONSTITUTION:A speed instruction unit B1 converts a displacement theta by an operating lever into an electric signal and outputs a command speed signal V10. The signal V10 is converted by an absolute value circuit B1 into a signal V12, which is applied to a neutral correcsion circuit B12. The circuit B12 outputs a command speed signal V1 which is zero when the inclining angle theta of the lever falls in the width of -theta0<=theta<=theta0 and gradually increases from the zero when the inclination of the lever is deepened. A power drive control circuit C drives a motor MR in response to the deviation between the command speed signal V1 and the actually running speed signal V2. In this manner, the impact at the starting time is reduced, and extremely slow speed running is enabled in the vicinity of the neutral range out of the neutral range.

Abstract: PURPOSE:To convert precisely even a minute current into a voltage by converting a voltage value of voltage source to be converted being connected between an output point of an operational amplifier and a reversal input terminal into a current value which is made to flow in a circuit output terminal and is correspond to the voltage value. CONSTITUTION:A voltage source V is connected between the reversal input terminal of an operational amplifier OPA and an output, a resistance R is connected between the output of the amplifier OPA and a output terminal A being drawn out from a non-reversal input terminal directly. And, the amplifier OPA causes output voltages to change so that the voltages being impressed to the non-reversal input terminal and to the reversal input terminal are to be equal. Accordingly, if the current being flowed from the terminal A is designated as a I0, V=R.I0, but, an input current of the amplifier OPA is considered to be able to ignore in comparison with the current I0. Here, for the input, if an object using a MOSFET is applied as the amplifier OPA, the current of a few PA or less is also able to precisely output to the current I0.
