Title: Optical reception equipment
Inventor: TAGAMI HITOSHI
IPC: H04B10/2507
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To decrease the circuit scale of optical reception equipment by connecting one terminal of a two-terminal type variable resistor, whose impedance is changed by an inter-terminal voltage, to the output of a signal amplitude detector and connecting the other terminal to the output of an optoelectrical converter. SOLUTION: If the peak value of an optical signal is increased, the output of a level converter 11 is changed to a low-order voltage side, and when the output of the level converter 11 is changed to a low-order voltage side, the inter-terminal voltage of a two-terminal type variable resistor 20 is increased. At this time, the two-terminal type variable resistor 20 is changed to a low-impedance side, and one part of a signal current outputted from an optoelectrical converting element 2 flows to the two-terminal type variable resistor 20.  Namely, even in the case of the maximum input amplitude of an optical signal for starting the saturation of an internal circuit of an amplifier 3 in the absence of a signal amplitude detector 7 and of the two-terminal type variable resistor 20, the signal current to flow to the amplifier 3 is decreased by the signal amplitude detector 7 and two-terminal type variable resistor 20. Consequently, the maximum input amplitude of the optical signal for starting the saturation of the internal circuit of the amplifier 3 can be expanded.

Title: Xy stage
Inventor: GOTOU HIROSHI
IPC: B23Q1/00
Filed: 1984-06-18
Abstract: PURPOSE:To reduce dead load of a stage as well as to aim at improvements in profitability for shift positioning and durability, by installing each reflector in two orthogonal cross guides driving the stage, making it reflect a laser beam, and detecting the beam at a guide position. CONSTITUTION:The laser beam emitted out of a laser length measuring instrument 11 is separated into its spectral components at a beam silitter 12 and radiated to each of reflectors X, Y, 7 and 8 via interferometers X, Y, 9 and 10, while the laser beam being radiated to the reflector X7 is reflected by the reflector X7 and received by a receiver X14 via the interferometer X9, so with this light receiving, a position in an X-axis of a stage 6 is detected. In addition, the the laser beam radiated to the reflector Y8 is as well received by a receiver Y15 whereby a position in a Y-axis of the stage 6 is detected and each detection value is processed, thus positioning for the stage 6 takes place. Doing like this, dead load of the stage is reduced, making inertia of the stage lower down to some extent, and wear in moving parts is therefore reduced so that assembling operation comes to being yet easier.

Title: Position adjusting device for work
Inventor: ISHII OSAMU
IPC: G03G15/04
Filed: 1986-05-31
Abstract: PURPOSE:To rotate and move a work by providing a couple of chucks, a couple of linear driving mechanisms, and a support mechanism. CONSTITUTION:When the rotating speed of one motor 23b is made larger than that of the other motor 23a, the stroke of one slide lever 25b becomes larger than that of the other slide lever 25a. Consequently, the movement distance of one vacuum cup 36b becomes larger than that of the other vacuum cup 36a, so a dimming plate 7c is moved slanting by the difference in movement distance between the vacuum cups 36a and 36b. At this time, the slanting of the dimming plate 7c is equivalent to the rotation of the dimming plate 7c around a certain point, so the vacuum cups 36a and 36b should rotate and be displaced relatively about a certain point. Here, a rotary lever 28 is fitted rotatably to the slide lever 25a through a pin 27, so the vacuum cut 36a can rotate relatively to the vacuum cup 3b by the rotation of the rotary lever 28.

Title: Power supply circuit
Inventor: TAKADA JUNICHI
IPC: G05F1/56
Filed: 1989-05-19
Abstract: PURPOSE:To speed up the rise of a voltage outputted from a power output terminal so as to immediately supply power to a load by speedily charging capacitor at the time of turning on a power supply. CONSTITUTION:A circuit in which a diode 14 and a resistor 15 are connected in serial is connected to a resistor 12 by setting the direction of the diode 14 in the direction of charging the capacitor 13 at the time of power supply. When a voltage is supplied to a power input terminal Ti, most currents are supplied to the capacitor 13 through the resistor 15 and the diode 14. Thus, the capacitor 13 is immediately charged. Consequently, the voltage of the capacitor 13 rises and the diode 14 becomes interrupted state. Then, a system is switched to the low pass filter of a time constant, which consists of the conventional resistor 12 and the capacitor 13, and reaches to a constant state. Thus, the rise of the voltage outputted from the power output terminal T0 is speeded up and power can immediately be supplied to the load.
