Title: Film exposing device
Inventor: SUZUKI SHIGERU
IPC: G03F7/20
Filed: 1990-08-10
Abstract: PURPOSE:To remove the partial blurring of a projected image and to accomplish exposure with high accuracy by providing a photomask holding angle adjusting mechanism or a projecting lens holding angle adjusting mechanism which can change the solid angle of a photomask or a projecting lens viewed from a point on an optical axis on a projection plane. CONSTITUTION:The photomask, holding angle adjusting mechanism is constituted of a supporting plate 31 whose center part is squarely holed, three supporting screws 34a-34c as a supporting pin, and a substrate 33 for supporting the three supporting screws. The photomask is arranged on the upper surface of the supporting plate 31 through a horizontal direction position adjusting mechanism and a rotating position adjusting mechanism. Then, the screw 34a is fixed on the substrate 33 and the screws 34b and 34c are screwed on the substrate 33 so that they can displace in an optical axis direction X. Therefore, the holding angle of the photomask arranged on the upper surface of the supporting plate 31 is adjusted by turning the screw 34b(34c), and the solid angle theta is changed. Thus, the partial blurring of the image is removed and pattern exposure with high accuracy is accomplished.

Title: Data transfer circuit
Inventor: SHIWACHI SHINICHI
IPC: G06F12/00
Filed: 1989-08-16
Abstract: PURPOSE:To improve the processing capability when plural CPUs processes in parallel by inhibiting the write or the read when both CPU accesses conflict with each other with the prescribed address value used as a buffer. CONSTITUTION:A dual port memory 1 is provided with a pointer WP for a write address and a pointer RP for a read address, and the RP changes at random with the CPUs of the 'plural' side. Both the write and the read are executed in the memory 1 at one time if the absolute value ¦WP-RP¦ of the difference WP-RP calculated by an address monitor part 3 is larger than the prescribed value M. However an underflow state is shown with 0<WP(1)-RP<M and therefore a read inhibition flag is produced to the CPU of the '1' side for read inhibition. Furthermore an overflow state is shown with 0<RP-WP(2)< M, therefore a write inhibition flag is produced to the CPUs of the 'plural' side for write inhibition. As a result, the processing capability is improved when plural CPUs carry out the processes in parallel with each other.

Filed: 1983-11-10
Abstract: PURPOSE:To inform immediately the abnormal voltage due to the generation of a fault by connecting a light emitting diode between a non-reverse input terminal and a reverse input terminal of a differential amplifying circuit. CONSTITUTION:The DC voltage produced between both terminals of a smoothing capacitor 11 is delivered between output terminals 16 and 17 via a transistor TR15 in the form of the output voltage V0. This voltage is applied to a non-reverse input terminal (+) of a differential amplifying circuit 18 via a resistance 19. While the reference voltage V0 is produced at a reference output terminal 20 of a reference voltage circuit 12 and then applied to a reverse input terminal (-). An output signal is produced so as to obtain the coincidence between the voltage V0 of the circuit 18 and the reference voltage VS. Then the base potential of the TR15 is controlled. If the TR15 has a short fault, a difference larger than the prescribed value is produced between voltage V0 and VS. Then a light emitting diode 22 emits light to inform the generation of the abnormal high voltage.
