Patent JP-H06177592-A (JP)
Title: Electronic component installation device
Inventor: SAKAGUCHI HIROYUKI
IPC: B23P21/00
Filed: 1992-12-02
Abstract: PURPOSE:To make it possible to detect the positions of various kinds of electronic components and moreover, to reduce the loss time to require for the detection to make it possible to transfer and mount the electric components on a substrate at high speed by a method wherein a mirror is selectively moved to one side of each electronic component attracted by a plurality of nozzles. CONSTITUTION:In the case where the position of a comparatively small-sized electronic component P1, such as a resistance chip and a capacitor chip, is detected, a mirror 13 is stepped forward to the lower part of the component P1 attracted by nozzles 15b in the middle of the movement of a transfer head 3 to the upper part of a substrate 4 and light from a light source 54 is made to reflect to the head 3, whereby the position of the electronic component is detected. Moreover, in the case where the position of a comparatively large-sized electronic component P2, such as a QEP and an SOP, is detected, the head 3 is moved to the upper part of an observation device and here, light is emitted from the light source 54 toward the component P2 and a diffuser panel 18c of light to observe the component P2 by cameras 52 and 53 and the position of the component P2 is detected. In such a way, detection of the positions of various kinds of chips can be conducted.

Title: Straight line device
Inventor: IIKURA SHOICHI
IPC: B25J5/02
Filed: 1987-12-22
Abstract: PURPOSE: To increase a speed and to miniaturize the moving base of a linear motion device used for the manipulator of a robot or the like by arranging a second moving base in a first moving base in a manner that the second base makes a linear motion in the same motion direction as that of the first base. CONSTITUTION: A screw shaft is rotated by the driving of a motor 26, and a first moving base 22 located in the neutral position of a fixed base 21 is moved by 1 in a right direction. By this movement, a second moving base 23 located in the neutral position of the fixed base 21 is pulled by a rope 25a, and by causing a block 24a to act as a running block, the second moving base 23 is moved in a right direction by a distance 21 twice as much as that of the first moving base 22. Thus, since the second moving base 23 is not driven directly by the motor 26, the second moving base 23 is miniaturized without providing any space for passing a screw shaft 27 or the like, and the influence of inertia thereof is reduced. Further, the wide moving ranges of the first and second moving bases 22 and 23 are set.

Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To more stabilize the switching operation by extracting an ON/OFF electromotive force of a switching element and then raising a voltage at the minimum portion of the ripple. SOLUTION: When a switching element 4 is on, an electromotive force generated in a power feedback winding Nf is stored in a choke coil L10 passing a fourth diode D10 to charge a second capacitor C2 through the loop of the second capacitor C2 and power feedback winding Nf. When a switching element 4 is off, an energy stored in the choke coil L10 charges the second capacitor C2 through the loop of the second capacitor C2 and a fifth diode D11, while a flyback energy generated in a reset winding Nr charges the second capacitor C2 through the loop of the second capacitor C2 and a second diode D2. The charged energy is fed back to the primary winding Np via a third diode D3 to result in the stable switching operation by increasing the voltage near 0 Volt part of the AC input voltage to be input.

IPC: H01L39/24
Filed: 1987-12-22
Abstract: PURPOSE:To obtain the title thin film giving high critical current density, by producing, under specified film-forming gas pressure through the physical deposition technique, composite oxide superconducting this film comprised mainly of specific composite oxide. CONSTITUTION:In the process for production, by means of physical deposition, of composite oxide superconducting thin film comprised mainly of a composite oxide of the formula (alpha is Ba or Sr; 0.01<=x<=0.2), the film-forming gas pressure in said physical deposition is brought to between 0.001 and 0.6Torr. If said gas pressure exceeds 0.6Torr, significant reduction in the critical current density of the superconducting thin film obtained will result, thus practicable thin film cannot be produced. On the other hands, if said pressure is lower than 0.001Torr, reduction in both the critical current density and critical temperature will result. In general, the film-forming gas to be used is a mixture of oxygen gas and an inert gas, said inert gas being argon.
