Title: Method for bonding narrow pitch lead device
Inventor: ISHIKAWA TAKATOSHI
IPC: H05K3/32
Filed: 1992-07-01
Abstract: PURPOSE:To bond the lead of a TAB device to the panel electrode of a panel element smoothly by aligning the panel electrode and the lead before coating a hardening resin and then coating resin on the panel electrode. CONSTITUTION:A panel element PN is sucked by a sucking part 41 for positioning it on a support stand. Then, a motor is driven to allow an upper surface 22a of a support plate 22 to oppose and to be the same level as a panel electrode PNb. A device P is sucked by a transfer means, the position of the device is roughly compensated while observing the device P with a camera, and the device is placed on the upper surface 22a. In this state, no resin B is coated on a lead L or the panel PNb, thus preventing observation from being interrupted and enabling alignment to be made smoothly. Then, the device P is moved in the longer direction of the panel electrode PNb, the resin B is coated on the panel electrode PNb while the lead L is removed, the device P is returned to the original position, and then the resin B is cured.

Title: Optimum control type semi-active suspension system
Inventor: KATSUTA TAKAYUKI
IPC: B60G17/015
Filed: 1991-06-18
Abstract: PURPOSE:To increase the damping effect of an optimum control type semiactive suspension system. CONSTITUTION:Optimum control force can be obtained by means of the damping force of a damper device in an optimum control type semi-active suspension system. Optimum control force u1 is computed at a step S9 based on state variable approach such as vertical relative traveling speed yv1 between above and under spring which are obtained at steps S4, S5. If the codes of the optimum control force u1 and the vertical relative traveling speed yv1, are the same, the judgment at a step S13 is YES, and control signal according to the optimum control force is made at a step S15. If the codes are different from each other, a control signal is made so that the opening degree may become maximum at a step S16. The opening of a variable check valve is controlled based on these control signals at a step S17. If feasible optimum control force is required, the absolute value of the damping force is set maximum to avoid a decrease in damping effect due to generation of improper damping force.

IPC: G10L25/72
Filed: 1981-10-30
Abstract: PURPOSE:To increase the degree of utilization of a transmission line by using a voice recognizing device and a voice synthesizer. CONSTITUTION:A voice signal from a microphone 1 is applied to a voice recognizing device 5, which recognizes respective elements of the voice signal such as syllables and clauses. Those recognized elements are applied to a transmission-side interface 6, where they are encoded into an information signal. This information signal is transmitted through a transmitter 7.

Those converted elements are applied to a voice synthesizer 10 to synthesize a voice, which is applied to a speaker 4. Consequently, the entire band of a transmission line is not used for the transmission of the voice signal, so plural communication systems are multiplexed through the transmission line with the same capacity, increasing the degree of utilization of the transmission line.
