Title: Production of semiconductor
Inventor: MIZUTANI HIDEO
IPC: G03F7/20
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To uniformize the illuminance distribution by eliminating the nonuniformity of illuminance on the plane of projection because the transmittance of light is not uniform in a projection optical system. SOLUTION: The illuminating light from its source 2 is projected into a mask 9 through the illumination optical systems 3, 4, 5, 6, 7 and 8 with the optical characteristics variable, and the light transmitted through the mask 9 is projected on a wafer 11 through a projection optical system 10 with the image forming characteristics changeable. Consequently, even when the transmission distribution is fluctuated due to a change in the image forming characteristic of the projection optical system 10, the optical characteristic of the illumination optical systems 3, 4, 5, 6, 7 and 8 are changed as the image forming characteristic of the system 10 is changed, hence a specified illuminance distribution can be obtained on the image forming surface, and the pattern on the mask 9 can be nicely transferred on the wafer 11.

Filed: 1978-10-27
Abstract: PURPOSE: To obtain the captioned machine which is applicable to a press extremely easily, by providing a mechanism to introduce the working fluid for press ram into the cylinder for punch ram and operte the both rams in mutual relation by double- acting system, to the slide end face of the press.  
     CONSTITUTION: A press ram 2 is pressed down by working fluid in a cavity 7, and upper and lower dies 15, 16 are brought to tight contact each other, while a punch 10 lowers together with a cylinder 9, so that relative movement does not occur between the two. A material 18 is deformed in primary processing. At this time, when the pressure of said working fluid is increased, the punch 10 is rapidly pressed down to advance into the material, which fills up the space 17. If the pressure of the working fluid is further increased, since the total volume of cavity 7, passage 11, and upper chamber 12 is large, and the pressure increase is canceled by the compression of the working fluid, so that the fluctuations of volume of the material 18 may be eliminated. When the pressure of the working fluid decreases, the ram 10 is raised by the pressure of the lower chamber 14, and the punch 10a is drawn out from the material. Next, a return cylinder 4 pulls up the ram 2, slide 1, and die 15 through a push-up ram 5, and the material is taken out.

Title: Alternating current 3-wire photoelectric switch
Inventor: WATANABE YASUYUKI
IPC: H03K17/78
Filed: 1978-10-30
Abstract: PURPOSE: To obtain a small-size photoelectric switch which can be used in common to AC 100V and 200V by lowering the driving frequency of the light emitting diode and increasing the peak value.  
     CONSTITUTION: When the half-wave rectified voltage start rising after passing through diode 11 of projector 1, the gate voltage of PUT17 continues to rise up until it is limited by the constant voltage diode. And the anode voltage rises up late by charging of capacitor 16, and PUT17 is kept off during the period of the half-wave rectified voltage. And capacitors 15 and 16 are charged. Accordingly, the discharge of capacitor 15 advances at the next half-wave rectifying time to eliminate the potential difference between the anode and the gate. Thus PUT conducts, and light emitting diode 20 is driven by the peak current caused by the sudden discharge of capacitor 16 and with the same low frequency as the AC power source even in case either of the 200V and 100V AC power sources is used and without any large-size electrolytic capacitor. As a result, a small-size structure is possible for the photoelectric switch consisting of the projector and the light receiver requiring no high amplification of the reception signal.
