Title: Display device
Inventor: KANEKO TAKAHISA
IPC: G09G3/20
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To reduce luminance irregularity of an EL panel. SOLUTION: When EL panels 9a, 9b are arranged in the scan direction, the EL panel 9b generates rounding as shown in (b) due to a wiring resistance of a scan electrode 20. However, the EL panel 9b having a voltage-luminance characteristic is used in which the EL panel 9b, when emits light at a voltage Vb, emits light at the same luminance Lo as the luminance Lo of the EL panel 9a at a voltage Va. The EL panel 9a having a desired luminance at a relatively high voltage is disposed near a scan driver IC 18, and the EL panel 9b having a desired luminance at a relatively low voltage is disposed far from the scan driver IC 18, so that luminance irregularity between the EL panel 9a and the EL panel 9b can be suppressed.  Even when a relatively low voltage is applied to the EL panel 9a and relatively high voltage is applied to the EL panel 9b, the luminance irregularity between the EL panel 9a and the EL panel 9b can be suppressed.

Title: Transporting mechanism for wafer
Inventor: AIKAWA HIROSHI
IPC: H01L21/68
Filed: 1986-11-05
Abstract: PURPOSE:To suppress generation of dust, by arranging a plurality of pulley in line at fixed intervals in a zigzag pattern of two arrays in parallel with each other at a fixed width, mounting a belt in the grooves of these pulleys and setting the upper surface of the belt at a position lower than the upper edges of the pulleys. CONSTITUTION:By arranging pulleys 10 in a zigzag pattern, friction force between pulleys 10 and a belt 20 can be enhanced. That is, by arranging the pulleys 10 in a zigzag pattern, the belt 20 touches the sidewalls of the grooves of pulleys 10 in tension state, not only the bottom surfaces of the grooves. Thus, by moving of the belt 20, a driving force of the belt is transmitted to the pulleys 10 and the pulleys 10 rotate. The upper surface of the belt 20 is at a lower position than the upper edges of pulleys 10, that is, the belt 20 is loaded in the pulleys 10 at the condition that the belt 20 is completely accommodated in the grooves of the pulleys 10. Thus, a wafer 40 has no contact with the belt 20 and is transferred having point contact with the upper edges of the pulleys 10. As the result, there is scarcely any danger that alien substances adhere to the back surface of wafer 40 being transported.

Title: Apparatus and method for measurement of harmonic electric power
Inventor: SHIRAI KOJI
IPC: G01R29/00
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To measure harmonic electric power which flows out to the side of a system from a power generation apparatus by a method wherein the difference in the harmonic electric power before and after the direction of a power flow in a receiving point is changed to the side of the system from the side of a load is found. SOLUTION: Electric power is supplied to a load 1 and a load 2 from a system via a receiving point P, and a voltage signal and a current signal in the receiving point P are input to a harmonic-electric-power measuring apparatus 4 via a PT and a CT. Normally, a current which flows in the receiving point P is only I1 , and a power flow is directed to a load-side direction A. On the other hand, when the power generation amount of a photovoltaic power generation apparatus 3 is increased, a part of it flows out to the side of the system via the receiving point P. A current I21 which flows out is larger than the current I1 , and a power flow in the receiving point P is directed to a system-side direction B.  The harmonic- electric-power measuring apparatus 4 fetches a voltage signal and a current signal for a definite period before and after a point of time in which the power flow is changed to the direction B from the direction A, and it measures n-order harmonic electric power within the period. Then, the difference in the harmonic electric power before and after the direction of the power flow is changed is found, and the difference is output as the amount of the harmonic electric power which flows out to the side of the system from the photovoltaic power generation apparatus 3.
