Title: Surface defect inspecting device
Inventor: NAKASHIMA TOSHIROU
IPC: G01N21/89
Filed: 1981-02-14
Abstract: PURPOSE:To equalize the detection accuracy, by deflecting a scanning pattern drawn by a light beam which is made incident to a light beam focusing means for focusing a light beam onto the surface of a material to be inspected, to a shape being similar to an external shape of the material to be inspected. CONSTITUTION:A light beam 2 from a laser light source 1 is reflected by driving mirrors 9a, 9b of a polarization means 9, and reaches a reflector 11. The  light beam 2 reflected by the reflector 11 is irradiated so as to form one coil- like uniform beam spot 14 extending over almost the whole circumference  except a shadow part (part shown by a broken line in the figure) of a material  to be inspected 3 through a convex lens 12. The light beam 2 scanned onto the  surface of the material to be inspected 3 is reflected and is irradiated as a reflected ray 5 to a photoelectric converting element of a detector 7. Accordingly,  when the material to be inspected 3 is moved in the axial direction, the reflected ray 5 can be obtained from almost the whole surface of the material to  be inspected 3, and a strong or weak variation of this reflected ray 5 is inputted to a processing circuit 15, by which whether a defect exists on the surface  of the material to be inspected 3 or not is detected.

Title: Magnetic recording medium
Inventor: FURUHATA KENICHI
IPC: G11B5/706
Filed: 1994-02-17
Abstract: PURPOSE:To enhance stability to an environmental change by regulating the magnetic characteristics of the magnetic layer of a magnetic recording medium to a prescribed range. CONSTITUTION:This magnetic recording medium has a first recording wavelength group consisting of one or plural kinds of wavelengths of >=10mum and a second recording wavelength group of the wavelengths shorter than these wavelengths. The magnetic powder of the magnetic layer applied on a nonmagnetic base consists mainly of hexagonal system ferrite magnetic powder having a specific surface area 25 to 80m<2>/g and a specific plate 2 to 7 of the magnetic powder. The large macromagnetic powder particles are formed and not only an effect of improving the recording and reproducing outputs at short wavelengths is lowered but also noises at the time of recording and reproducing are drastically increased and S/N is lowered if the specific surface area of the magnetic power is below 25m<2>/g and, therefore, such specific surface area is undesirable. Conversely, the excessively small magnetic powder particles are formed and the viscosity increase at the time of forming a coating material by dispersing the particles into the resin binder is drastic if the specific surface area exceeds 80m<2>/g.

Abstract: PROBLEM TO BE SOLVED: To reduce the weight by providing protrusions for introducing the air flow in the rotational direction of a turbo fan to the direction of the rotary shaft thereof of the lower surface of a top plate thereby enhancing the strength of the top plate and making thin the top plate. SOLUTION: Triangular prism protrusions 10 for partially restricting the gap to a turbo fan 4 are provided on the lower surface at the planar part of a top plate 1.

An air flow is generated in the space between the top plate 1 and the turbo fan 4 through rotation thereof. The air flow is introduced to flow along the longitudinal wall face on the oblique side of the triangular protrusion 10. The introduced air flow strikes a fan motor 3 which is thereby cooled. Since the top plate 1 can be set horizontally, the air-conditioner body can be made thin.

Title: Water jet cutting device
Inventor: ASANO MASAHARU
IPC: B26F3/00
Filed: 1992-02-06
Abstract: PURPOSE:To surely and easily judge the quality of cut by providing an outputter for outputting a cut failure when the detection output of a vibration detector is below a determined level over a fixed time at the time of cutting a material to be cut. CONSTITUTION:When an ultra high pressure water is passed through a material 3 to be cut and received by a catcher tank 4, the detection output by a vibration detector 5 is high. However, when the ultra high pressure water is not passed through the material 3 to be cut nor received by the catcher tank 4, the detection output by the vibration detector 5 is low. When the detection output of the vibration detector 5 is below a determined level over a fixed time, a cut failure is outputted through an outputter 6a. Thus, the quality of cut is judged according to whether the ultra high pressure water is passed through the material 3 to be cut or not.

Abstract: PURPOSE:To form a stable pulse signal by constituting a titled circuit so that a pulse signal is supplied to a gate which is closed for the time of the pulse width to eliminate a signal with distorted edge waveform from an input signal. CONSTITUTION:When an output B from an amplifier 10 goes from ''L'' to ''H'' and an output B2 of a gate 51 goes to ''L'' to ''H'', the output B is inhibited during a time when the leading times are different, and a pulse having the pulse width eliminating the distortion of edge waveform from the leading edge of the output B is obtained at a terminal 130. Then, the output B from the circuit 10 falls down from ''H'' to ''L'', the output B2 of the gate 51 falls also down from ''H'' to ''L'', an output B3 of an inverter 60 rises from ''L'' to ''H'' and an output P2 of an AND gate 41 rises also from ''L'' to ''H'', thus an NOR gate 51 is closed and the output B1 from a gate 50 is inhibited afterward while the output P2 of the gate 41 goes from ''H'' to ''L''.

Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To improve the communication efficiency at interruption of power and its workability by delivering copy management data to a data communication equipment and storing the data therein. SOLUTION: In the case that a copying machine 101 receives a polling request from a data communication equipment 120, the copying machine 101 delivers copy management data at that point of time in response to the polling to the data communication equipment 120. Furthermore, when the copying machine 101 receives a selecting request from the data communication equipment 120, the copying machine 101 outputs an affirmative response to the data communication equipment in the case that the copying machine 101 copes with the request to start the communication. The data communication equipment 120 sends the data obtained by the response to a central processing unit and stores the data to its own machine when the data are copy management data. Thus, even when power of the copying machine 101 is interrupted, the central processing unit reads accurate copy management data of the copying machine 101 via a communication line 130 and the data communication equipment 120.

IPC: G06F12/06
Filed: 1989-01-31
Abstract: PURPOSE:To decrease the number of components and to reduce costs by applying an address signal from the exclusive address terminal of a CPU through an address bus directly to the exclusive address terminal of a peripheral element part. CONSTITUTION:The address signal (high-order address signal) outputted from a CPU 1 to a peripheral element part 3 is applied by an address bus 5, which connects the two terminals out of exclusive address terminals A8 to A12 of the CPU 1 and exclusive address terminals A0 to A1 of a peripheral element part 3. In addition, a multiplexed address/data bus 8 functions as a transmission path at the time of exchanging the respective types of data between the peripheral element part 3 and the CPU 1. Consequently an external ROM 2 is unnecessary due to the masking of a ROM to be made built-in the CPU 1, not only the external ROM 2 but also an address latch element 4 can be removed. Thus the number of the components can be decreased, and the costs can be further reduced.
