Abstract: PROBLEM TO BE SOLVED: To enable accurate positioning of a wafer by executing position detection of mark having formed a surface layer film using a position detecting offset after formation of the surface layer film in the mark forming area on the wafer. SOLUTION: A wafer is supplied to a stepper ST to detect an alignment mark signal with an alignment scope and a signal information of the alignment mark is sent to an offset analyzer OA from the stepper ST. Subsequently, from the three-dimensional relative positional relationship of the resist obtained previously with an offset analyzer OA and a wafer mark, relationship between the alignment mark signal and the wafer mark position is obtained to calculate the offset in the alignment measurement and it is then sent to the stepper ST. The stepper ST executes the exposure through alignment based on such an offset and thereafter carries the wafer to a developer DV for the purpose of development. The circuits are then formed through several processes and thereby a semiconductor device can be obtained.

Abstract: PROBLEM TO BE SOLVED: To provide an output on/off circuit for a multiple output switching power source, in which the breakdown of a discharge element is prevented by reducing the discharge current of a discharging element for discharging load side capacitance charges, when an output on/off switching element is turned off. SOLUTION: A switching time for a control element Q4, which controls the turning on and off of a discharging element Q3 discharging charges of a load side capacitance C2 by causing a switching element FET Q2 to be turned off with a signal from a load side which is inputted from a signal input terminal 7, is controlled by time constant circuits R2, C4. The breakdown of the discharging element Q3 is prevented by restraining the peak value of a discharging current of the discharging element Q3, when the switching element FET Q2 is turned off. Thus use in the optimum operation region is made possible.

Abstract: PROBLEM TO BE SOLVED: To prevent the reduction of use efficiency and luminance of illuminating light and to reduce the power consumption. SOLUTION: With respect to a liquid crystal panel P2 , a lightproof layer 31 which intercepts illuminating light from a back light device B1 has a rear face 31b made of a member having a high reflection factor (for example, aluminum). Consequently, the attenuation rate for reflection on the rear face 31b of illuminating light from the back light device B1 is reduced, and the use efficiency of illuminating light is improved. As the result, the luminance of the liquid crystal panel P2 is improved, and it is unnecessary to use the back light device B1 having a high luminance, and the power consumption is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a display device capable of withstanding strong impact without hindering the trend toward the larger area of a display screen, the smaller thickness of the device and the lighter weight of the device. SOLUTION: A casing member 7 is arranged apart a prescribed distance on the rear surface of a liquid crystal panel 1. A display plate 9 having transparent parts to allow the viewing of the display region of the liquid panel 1 is arranged on the front surface of the liquid crystal panel 1. A first elastic member 8 is arranged between the liquid crystal panel 1 and the casing member 7 in the position enclosing the display region of the liquid crystal panel 1 to form an approximately hermetic space 12 enclosed by the first elastic member 8, liquid crystal panel 1 and the casing member 7. Further, a second elastic member 11 is arranged between the liquid crystal panel 1 and the display plate 9 in position enclosing the display region of the liquid crystal panel 1 to form an approximately hermetic space 13 enclosed by the second elastic member 11, the liquid crystal panel 1 and the display plate 9. The impact is absorbed by the air damper effect of the approximately hermetic spaces 12, 13 and the elastic force of the respective elastic members 8, 11 according to such constitution, by which the impact resistance performance is enhanced.

Abstract: PURPOSE:To make it possible to decrease reflected light from a protective plate, etc., and to permit easy recognition of the display contents of a liquid crystal panel. CONSTITUTION:Information is displayed on the liquid crystal panel 2 and a back light device 5 irradiates the liquid crystal panel 2 with light when the device is driven. The information displayed by the liquid crystal panel 2 is recognized when the panel 2 is viewed via a protective plate 27 in this state. On the other hand, even if the protective plate 27 or polarizing plate 23 is irradiated with the light from a light source existing outside the liquid crystal display device 20, the surfaces thereof are subjected to a diffusion treatment and therefore, the light cast thereto is not reflected. Then, only the light of the back light device 5 transmitted through the liquid crystal panel 2 is recognized and the recognition of the information is facilitated.
