Title: Method for adjusting back-light luminance of liquid crystal
Inventor: NAKAMURA AKIYOSHI
IPC: G02F1/133
Filed: 1988-03-08
Abstract: PURPOSE:To maintain an excellent displaying quality suitable for an ambient temperature by measuring the temperature in an apparatus and changing the luminance of the back-light of liquid crystal in accordance with the temperature. CONSTITUTION:Since the resistance value of a thermistor 4 changes when the temperature inside an apparatus main body changes, the frequency of a signal line 5 changes in accordance with the temperature inside the main body and, as a result, the temperature inside the main body can be recognized. The luminance of the back-light of liquid crystal is changed in accordance with the recognized temperature. When, for example, the temperature inside the main body is low, a transistor 9 is turned on through a signal line 8. Then the voltage value of a power source 7 for driving a cold cathode-ray tube type fluorescent lamp 20 can be boosted and, as a result, the luminance of the lamp 20 can be raised. Thus excellent luminance is obtained even when the temperature is low and, at the same time, the time until an excellent displaying quality is obtained can be shortened.

Title: Aligning method for exposing semiconductor
Inventor: NAKADA TOSHIHIKO
IPC: H01L21/30
Filed: 1988-03-10
Abstract: PURPOSE:To prevent decrease in accuracy due to application irregularities and the like, by detecting the interference pattern of reflected light from a wafer and an aligning, pattern on a reticle with an optical system, and relatively aligning the reticle and the wafer by the obtained aligning quantity from the central position. CONSTITUTION:An image from a two-dimensional solid-state image sensing device 47 undergoes optoelectronic transducing action and an interference pattern 79 is obtained. The information of the intensity distribution of the interference pattern 79 is sent into a computer 49 after the removal of noises and the AD conversion by a pretreatment circuit 48. In the computer 49, the information is compressed in the direction perpendicular to the position detecting direction, and a one-dimensional signal is obtained. The central position xw of an aligning pattern on a wafer is obtained from the symmetry of the waveform of the signal. An aligning quantity   and its direction are obtained from the position deviation from the central position xr of the aligning pattern on a reticle. A stage 4 is finely moved in the direction (x) based on the quantity   and the direction. The alignment in the direction (y) is performed by the same way. When the alignment is finished, exposing light is projected from an exposure system. Thus, the circuit pattern on the reticle is printed on the chip on the wafer 3.

Title: Power generating device in universal space
Inventor: KAIHO KATSUHARU
IPC: F03G7/06
Filed: 1986-03-14
Abstract: PURPOSE:To enable the generation of a high power without need to supply fuel or charge, by a method wherein a storage, making a pair of fluid for driving an expansion turbine, is rotated so that an irradiation-with-sun position and a shield-from-sun position alternately change places with each other. CONSTITUTION:When, in a universal space, a storage tank 3a is irradiated with the sun S, and a storage tank 3b is shielded by a shield plate 1, fluid 2, e.g., fleon, in the storage tank 3a is gasified. After the gasified fleon rotationally drives an expansion turbine 5, it enters the storage tank 3b for condensation. In this case, since a device is rotated at proper angle around a rotary shaft X so that the positions of the storage tanks 3a and 3b change alternately places with each other based on the shield plate 1, the flow of the fluid 2 is reversed each time the storage tank is rotated by a half turn, and a power can be continuously generated. This constitution enables the generation of a high power by means of solar energy in a universal space without need to supply fuel and charge.

IPC: H03H5/02
Filed: 1984-03-24
Abstract: PURPOSE:To set and change an optimum resistance value of a device to be measured or a desired resistance value simply and quickly by connecting a variable resistor section as a prescribed circuit resistance of the device to be measured, stopping the step operation of the variable resistor section with an output of a comparison means and displaying the operation on a display means. CONSTITUTION:When an input device 1 inputs a desired resistance value, e.g., 15kOMEGA at first, a CPU2 gives an output displaying 15kOMEGA to the display device 3 and an output bringing the variable resistor section 4 to 15kOMEGA. Thus, the display device 3 displays the resistance value as 15kOMEGA and relays RY1, RY4 and RY10 are activated in the variable resistor section 4 by transistors T1, T4 and T10 turned on, and contacts r1, r4 and r10 are thrown to the position shown in dotted lines so as to open a short-circuit device. Thus, the resistance value between terminals O1, O2 is set to 15kOMEGA. The desired resistance value is obtained between the terminals O1 and O2 through the simple operation inputting the desired resistance value from the input device 1 in this way.
