Filed: 1986-09-04
Abstract: PURPOSE:To achieve a higher accuracy, by automatically altering the color of an image of an object to be measured to a different one by a reticle display altering means when the image is the same in color as a reference reticle. CONSTITUTION:A video signal (i) outputted from a TV camera 10 is compared with a intermediate brightness level signal by a comparator 52 of a reticle display altering means 46. When the level of the signal (i) is higher than the intermediate brightness level signal, that is, the image is closer to white than halftone, a changeover switch 56 is switched to a terminal 62 side and a black/ white reference line is projected on a TV 11 according to a changeover timing of a changeover switch 48 by a combination control signal I. When the level of the signal (i) is lower than the intermediate brightness level signal, that is, the image is closer to black, the switch 56 is switched and a white reference line is projected on the TV 11. This enables very clear distinction between the image of an object to be measured and the reference reticle thereby achieving a higher measuring accuracy.

IPC: B41J5/30
Filed: 1987-08-24
Abstract: PURPOSE:To improve print processing efficiency as well as memory availability by using the print data storing area of a memory as a circulating memory. CONSTITUTION:It is decided that no data is stored in a print data buffer memory 10 and another routine is started when a stored address and a taken-out address coincide with each other through comparison. If no coincidence is obtained between both addresses, it is known that the memory 10 includes the data. Then said data is taken out of the memory 10 and the taken-out address receives +1 and stored in a print data extracting address pointer 12. In this case, the head address of the memory 10 is reset in case the take-out address reaches the final address of the memory 10 serving as a print data area. Then data are continuously taken out. These operations are continued so that the memory 10 serving as the print data area of a RAM 4 can be used as a circulating memory. Thus it is possible to improve the processing efficiency and the memory availability.

Abstract: PURPOSE:To speed up the reading-out operation of a BiCMOS static type RAM by speeding up the operation with the sufficient amplification rate of the output amplitude of a sense amplifier. CONSTITUTION:Inductances of an input MOSFET P9 and PA are selectively changed by a microsignal transmitted via a complementary common data RC 0 of the sense amplifier SA 0, by which the base-emitter voltage of cross-coupled driving transistors(TRs) T1, T2 is changed. A difference is, therefore, generated in collector current and is positively fed back to the bases of the driving TRs T1, T2, by which the potential of the data bus RDB for reading out of non- inversion and inversion outputs of the sense amplifier SA 0 and is rapidly expanded as the prescribed level to be determined by the on resistances of the driving TRs T1, T2. As a result, the operation of the sense amplifier SA 0 is speeded up and the reading-out operation of the BiCMOS static type RAM is speeded up.

Filed: 1992-08-06
Abstract: PURPOSE:To downsize a device, and improve a maintenance characteristic by replacing a conveying mechanism of a material to be heated with a mechanism formed by using freely rotatable rollers and gears instead of a through- conveyor. CONSTITUTION:A torque energizing mechanism 19 is formed of a driving device 8, a sprocket wheel 9 and a roller chain 10. When torque is energized to the first gear 15 of a conveying mechanism 18 by means of the torque energizing mechanism 19, respective rollers 14 formed integrally with the first gear 15 are rotated in the same direction by means of the second gear 16 meshed with the first gear 15. Thereby, a material 12 to be heated is heated to a prescribed temperature while being conveyed toward the other end from one end of an induction heating coil 1. Thereby, In the case where the induction heating coil is replaced, when the roller chain 10 of the torque energizing mechanism 19 is disconnected, since the conveying mechanism 18 can be taken out in a lengthwise direction, the induction heating coil 1 can be replaced easily. Since a wheel to support a through-conveyor 2 becomes unnecessary, a device can be downsized.
