Title: Panel device
Inventor: GO KENJI
IPC: E06B3/01
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To provide a panel device which is not particularly increased in rigidity of the panel and can prevent deflection of the panel when the panel is moved. SOLUTION: A panel 2 is supported by a pair of coupling arms 27 at lower right and left side edges and a pair of coupling plates 10 at upper central portions. The coupling arms 27 are moved along a vertically arranged first guide rail 13 by means of a lower side moving chain 24, and the coupling plates 10 are moved along a horizontally arranged second guide rail by means of an upper side moving chain 36. A driving force from a motor 41 is distributed to both the chains 24, 36 by a differential device 51. In this case, a bending load is applied particularly on the central portion of the panel 2 as the panel 2 is moved from an originally erected location to a refuge location. However, the central portion of the panel 2 is supported by the coupling plates 10, and therefore stress to the bending load can be applied, which can contribute to improvement of the strength of the panel 2.

Title: Differential amplifier circuit
Inventor: NAKAYAMA ISAO
IPC: H01L27/04
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To attain accurate A/D conversion by allowing a switch circuit to select one of constant voltage sources matching a reference voltage of an A/D converter connecting to a next stage. SOLUTION: When a voltage at a noninverting input terminal is lower than the voltage at an inverting input terminal of an operational amplifier OP1, an output voltage of the OP1 is higher, the base voltage of transistors(TRs) Q9, Q10 rises and large collector current flows. Thus, the emitter voltage of TRs Q3, Q4 and the collector current of differential pair TRs Q5, Q6 are decreased and the base voltage and the emitter voltage of TRs Q7, Q8 are increased. Thus, the voltage at the inverting input terminal of the OP1 gets higher and the feedback is established.  When voltages of constant voltage sources V3-V5 are set as a band gap regulator voltage, the voltage produced between a power supply voltage and ground voltage through a resistor divider and an applied voltage from the outside of an IC, a DC voltage at an output of the differential amplifier circuit is equal to the voltage with different characteristics from the constant voltage sources V3-V5 through the selection by a switch SW1.
