Title: Method for ultrasonic flaw detection
Inventor: UCHIDA KUNIHARU
IPC: G01N29/04
Filed: 1981-03-06
Abstract: PURPOSE:To reduce the noise echo, by detecting flaws while changing the angle of incidence to a region, where flaws should be detected, by every minute angle and superposing these ultrasonic signal waveforms. CONSTITUTION:A delay time controller 4 causes oscillators 1, which are selected by a program to radiate ultrasonic waves at a prescribed repeat period in accordance with a delay time which is set in accordance with the transmission direction and the focusing length of ultrasonic waves by a computer 5. An ultrasonic receiver 3 receives the signal of an oscillator selected by a command from the computer 5 and amplifies and filters this signal on occasion and inputs it to a high-speed A-D converter 6. The waveform made into a digital signal is inputted to a digital adder 7, and signal waveforms of m-number oscillators which are so selected that their signals should be received are added digitally. By this constitution, transmission and receiving directions of ultrasonic waves are deflected by every minute angle to detect flaws, and waveforms obtained by digital addition are added successively. The resultant waveform is discriminated by the computer 5 and is displayed on a display equipment 8.

Title: Magnetic head loading mechanism of floppy disk driver
Inventor: ISHIHARA SHIGERU
IPC: G11B5/54
Filed: 1983-02-28
Abstract: PURPOSE:To attain the forward and reverse revolutions of a cam which turns a support arm for magnetic head by attaching a spring and a conductor made of a shape memory alloy to said cam and therefore making use of the shape memorizable characteristics obtained by the heating and cooling of the conductor. CONSTITUTION:A cam 16 is set at the side of a support arm 14 and has a chevroned form with two arms 17 and 18 which are orthogonal to each other. A fulcrum 19 at the top of the chevron is supported rotatably by a shaft attached in parallel to the rotary shaft of the arm 14. The arm 18 is set rectangularly to the arm 14; while the arm 18 is set approximately in parallel to the arm 14 respectively. The revoltuions of the cam 16 are transmitted to the arm 14 via a lever 20. When the cam 16 has forward revolutions on the basis of the fulcrum 19, the lever 20 moves up the arm 14. While the arm 14 moves down by its empty weight when the cam 16 has reverse revolutions. As a result, a space where a magnetic head loading mechanism of a floppy disk driver is reduced to attain a thin and small sructure for the floppy disk driver as a whole.

Filed: 1987-02-13
Abstract: PURPOSE:To judge automatically and rapidly whether or not the ink jetting operation is good, by a method wherein a rotatable cylinder is used as a recording medium and a cleaner eliminating ink particles recorded on a recording surface of the recording medium after photographing is provided. CONSTITUTION:An ink head 1 is driven due to a drive signal from the external and, thereby, ink particles are emitted from respective emitting ports at the same time to be sprayed in alignment on a recording surface A of a recording medium 8 to be recorded. The recording surface with the ink particles is traveled as a cylinder 8 rotates, until it reaches the focal position of a camera 5. At this time, the camera 5 actuates by a timing signal to photograph the ink particles on the recording surface and outputs a photograph image to a signal processor 6. The signal processor 6 conducts the signal-processing of the photograph image of the ink particles and makes a display 7 display the image and judges whether or not the ink jetting operation of the ink head is good. After that, the ink particles on the cylindrical recording surface A, which were photographed by the camera 5, are removed by a cleaner 9 at the completion of photographing as the cylinder 8 rotates. Therefore, the evaluation of the ink head can be conducted automatically and rapidly.

Title: Still picture reproducing method for information recording disk
Inventor: HIRATA ATSUMI
IPC: H04N5/93
Filed: 1985-02-21
Abstract: PURPOSE:To prevent the deteriolation in reproducing picture quality by reproducing or reproducing/stopping the specified range within a disk by the sensor simultaneously when image signals of a stored image memory are repeatedly read and outputted. CONSTITUTION:Just after a still release instruction is performed, next address is searched. After its completion, the control command for indication of reproduction is supplied to a reproducing device 3, which starts reproduction from the next address of the disk. After the search processing is completed, a computer 1 supplies control signals to a switch circuit 5, connects terminals (a) and (c), and then the image signal which is reproduced from the disk with the reproducing device 3 is supplied and displayed. Thus, the image signal of the image memory 4 is outputted during still reproduction and the sensor of the reproducing device 3 scans the specified range on the disk independently of still reproduction, or separates from the disk. Accordingly the repetitive scanning time per same track becomes shorter to prevent the deteriolation of the picture image.

Title: Photoreceptor
Inventor: SAITOU KEISHI
IPC: H01L31/0248
Filed: 1984-02-24
Abstract: PURPOSE:To enable an image to be formed with a monochromatic light capable of causing light interference by forming a pair of nonparallel interfaces or more in a short range on the surface of a photoreceptive layer contg. A-Si and one of O, C, and N, and arranging a large number of said interfaces in one direction on the surface perpendicular to the layer thickness direction. CONSTITUTION:Interfaces having at least one pair of nonparallel interfaces in a short range of 0.3-500mum are formed on the surface of a photoreceptive layer 1000 contg. A-Si and one of O, C, and N, and a large number of said interfaces are arranged in one direction on the plane perpendicular to the layer thickness direction regularly and periodically. The nonparallel interfaces are formed in accordance with the regular roughness of the surface of the support 1001, and its roughness is composed of inverted V-shapes protuberances. On the whole, in such a photoreceptor 1000, the more the number of layers increase, the more of the interference effect can be prevented. Since the interference fringes in the minute parts are smaller than the diameter of the illumination light interference spots, they are smaller than the resolution limit, and causes no trouble, thus preventing the interference fringes.

Abstract: PURPOSE:When a fiber bundle is predrafted, wetted, squeezed and main-drafted, water is further added to the bundle to effect uniform wetting of the yarn, thus preventing uneven drafting, filament-winding around the draft rollers. CONSTITUTION:The fiber bundle Y is predrafted with rollers 1,1' and 2,2' in the predrafting zone and water is added from the whirl nozzle 3 to the bundle Y to wet the outer periphery of the yarn. Then, water is jetted perpendicularly to the axis of the yarn Y toward the center of the yarn from the jet nozzle 4 to wet the core part of the yarn. The yarn is made to pass through between  squeezing rollers 5,5' to move the excessive water to the outer layer, resulting in uniform wetting all over the yarn. The yarn is squeezed with the nozzle 6 to reduce the water and further squeezed with the back rollers 7,7' in the main drafting zone M. Subsequently, water is supplied from the nozzle 8 to make the yarn contain a certain amount of water, drafted with rollers 7,7' and 9,9', false- twisted, dried and wound up.

Abstract: PURPOSE:To improve the leading characteristic of a transmission wave by providing a reception/transmission switching signal cancelling the filter response characteristic of a power control loop and a differentiation circuit so as to prevent the excess input at switching to the power amplifier section. CONSTITUTION:In switching the state from a reception state A to the transmission state B, the attenuation of a voltage controlled attenuator 2 is minimized momentarily by the effect from the response characteristic of a loop filter 8 and reaches the steady-state by a time constant of the filter 8.
