Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a driving circuit technique for a printing head capable of effectively preventing waste of energy that has been neglected in the charge and discharge process of a printing head using a capacitance element such as a piezoelectric element. SOLUTION: In the case the number of driving nozzles is less than a predetermined number, a charge side controller 1 switches off a transistor Tr31, and on/off a transistor Tr33. Moreover, a discharge side controller 2 switches off a transistor Tr32, and on/off a transistor Tr34. By a second inductor (coil) L2 having an inductance value smaller than that of a first inductor (coil) L1, the voltage υc of a print head H is smoothed as well as the discharge energy is accumulated. Accordingly, waste of energy can be prevented by using a coil with a small inductance at the time of a light load, that is in the case the capacity CL of the printing head H is small.

Abstract: PURPOSE:To make it possible to obtain the image of a cross section similar to the image in a destructive inspection by projecting the X rays from a microfocus X-ray tube on the can winding and tightening part of a can under inspection, and receiving the fluoroscopic data with an X-ray image intensifier or an X-ray line sensor. CONSTITUTION:A microfocus X-ray tube 1 projects the X rays in the tangential direction with respect to a can winding and tightening part 20 of a can 2. The transmitted X-ray image is converted into the visible image with an X-ray image intensifier. A camera head 4 picks up the output image of the intensifier 3. A camera controller 5 converts the signal from the head 4 into the image signal. An image processing device 6 performs the processings such as noise reduction and profile intensification for the image signal. The distance between the focal point of the X-ray tube 1 and the input surface of the intensifier 3 is made sufficiently larger than the distance between the focal point of the X-ray tube 1 and the winding and tightening part 20. Thus, the magnified X-ray image is obtained. The signal from the device 6 is inputted into an image display device 7, and the shape of the magnified cross section of the winding and tightening part 20 is displayed. In this way, the inspecting person can observe the expanded image of the cross section similar to the image in a destructive inspection and can smoothly inspect the part 20 without sense of incompatibility.

Title: Input buffer circuit
Inventor: HOTTA YASUHIRO
IPC: H03K17/16
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To prevent malfunctions and to expand operation margin, even if the electric potential of a power supply line or a ground line fluctuates by a noise signal by inducing the electric potential an external signal to be inputted in the direction of potential change of the power supply line or the ground line and organizing them, so that an external signal does not exceed an input logical threshold. SOLUTION: Each RC delay circuits consist of P-type and N-type field effect transistors TP0 and TN0, each of these gate capacities and resistance elements RP and RN. They and a resistance element R1 constitute an input buffer circuit 10. When an output signal DIX changes to either 1 or 0, the transistors TP0 and TN0 induce the electric potential of an inputting part in the direction that is the same as the one in which a ground line GND or a power supply line Vdd change due to instantaneous current. Each RC delay circuit relieves a noise signal that occurs on the ground line GND and the power supply line Vdd. With this, even if the logical threshold of the circuit 10 is changed by a noise signal, an external signal DI follows the change of logical threshold, and the inversion of an internal signal DIX does not occur.
