Filed: 1989-03-02
Abstract: PURPOSE:To manufacture the title apparatus suitable for community health screening at proper cost by providing a film feed means for moving a film recording the output image of an X-ray image converting means at a variable speed. CONSTITUTION:A exposure slit is cut in the X-ray shield plate provided to the opposed surface of an X-ray source in an arch shape and an X-ray fluorescent multiplier tube (image tube) as an X-ray image converting means is provided in such a state that the X-ray input surface thereof is allowed to approach said slit. The X-ray beam emitted from the X-ray source with the revolution of a horizontal arm momentarily irradiates a dental arch or head cervical part of an examinee along the tomographic track thereof and an X-ray tomographic image transmits through the above mentioned exposure slit to be incident to the X-ray input surface of the image tube. When an object is the head cervical part, a film runs in the same direction as the revolving direction of the arm so as to conform to the tomographic track of the object by the driving of a variable speed motor 31 such as a pulse motor receiving the signal of a control circuit to be controlled in its rotational speed and, when the revolution of the horizontal arm is completed, a panoramic image having a predetermined length is formed to the film. By this method, a panoramic X-ray indirect imaging apparatus optimum to community health screening and also proper at cost is obtained.

Title: Manufacture of patterned photoconductor element
Inventor: MATSUO MINORU
IPC: H01L31/0248
Filed: 1989-03-01
Abstract: PURPOSE:To enable fine patterns to be formed easily and at a high aspect ratio by forming a photosensitive layer on the whole surface of a conductive substrate and masking the photosensitive layer in desired patterns with a transparent metal and heating the substrate under a vacuum for reevaporating the non-masked part of the photosensitive layer to pattern the photosensitive layer. CONSTITUTION:A photosensitive layer 2 is formed by vapor depositing a photoconductive material on the whole surface of a conductive substrate 1. The photosensitive layer 2 is then masked in desired patterns of a transparent electrode 3 by application, vapor deposition or the like of the transparent electrode. Subsequently, the substrate is heated under a vacuum whereby the non- masked part of the photosensitive layer is reevaporated while the masked part is not. As a result, the photosensitive layer is patterned in the desired patterns. Finally, a protecting layer 4 if required is formed by application or vapor deposition of a transparent protecting material, The transparent electrode material used as the patterned mask should be a material not evaporated in the reevaporation process, and such material may be a metal such as Al or Au or a transparent conductive material such as SnO2, InO3, ITO or TiO2.

Abstract: PURPOSE:To facilitate the manufacture of a diffraction grating by using a photoresist film which is sensitive to ultraviolet rays as a mask for diffraction grating formation and using a photoresist film which is sensitive to far ultraviolet rays as a phase plate which shifts laser light in phase. CONSTITUTION:The photoresist film 22 which is sensitive to not far ultraviolet rays, but ultraviolet rays, an intermediate layer 23, and the positive type photoresist film 24 which has sensitivity to far ultraviolet rays are laminated on a substrate 21 in order. Then, the film is exposed to far ultraviolet rays through the mask and developed to remove a specific part of the film 24. Then, the film is exposed to two near ultraviolet rays (e.g. He-Cd) from above the film 24, and then the entire surface is exposed to far ultraviolet rays and the film 24 is developed and removed. Then, the layer 23 is removed and the film 22 is developed to form the film 22 in a diffraction grating pattern which shifts by 1/4 wavelength. Then, the substrate 21 is etched by using the film 22 as the mask. The diffracting rating which shifts in pitch by 1/4lambda is easily manufacture by this method.

Title: Laser diode drive circuit
IPC: H01S5/042
Filed: 1992-03-10
Abstract: PURPOSE:To prevent a drive circuit of more than the highest current from being flowed through a laser diode by a method wherein a laser diode drive circuit is provided with a drive current control part for limiting the drive current regardless of a control signal. CONSTITUTION:A current detecting part 3 detects a drive current, which is fed to a laser diode, and the detection signal is added to a comparison part 4. The part 4 compares a set limiting value with the detection signal from the part 3. When a comparison output signal to show that the drive current exceeds the set value from the part 4 is not added to a drive current control part 6, the control part 6 controls a transistor 2 according to a control signal from a light output control part 5. When the comparison output signal is added to the control part 6 from the part 4, the control part 6 limits the drive current, which is fed via the transistor 2, even if the control signal to show an increase in the drive current is added to the control part 6 from the control part 5. Accordingly, the laser diode 1 can be protected from an excessive current.

Filed: 1984-03-16
Abstract: PURPOSE:To obtain an extremely safe and highly reliable robot, by providing a rotary encoder, position detector, abnormality detector, and safety processing section and quickly setting the robot to an operation-disable condition when signal lines are disconnected or short-circuited. CONSTITUTION:When, for example, line disconnection occurs at a rotary encoder 8, a Z-counting section 22 counts the zero signal of the encoder 8 and, whenever timing pulses are inputted, outputs the increased quantity to the detecting section 23 for detecting abnormality in zero signal of an abnormality detecting section 17. The detecting section 23 discriminates existence/nonexistence of abnormality by inspecting the increased quantity of the zero signal of the encoder 8 at every timing pulse. In this case, the increased quantity at every timing pulse is detected as zero or very small quantities. In response to the abnormality detected at the detecting section 17, a safety processing section 18 promptly stops the robot when, for example, the robot is operated, and fixes the attitude of the robot main body by a brake, etc., so as to set the robot to an operation-disable condition.
