Title: Fitting plate for ae sensor
Inventor: YOSHIMURA KIYOKAZU
IPC: B23Q17/09
Filed: 1985-10-03
Abstract: PURPOSE:To detect the abnormality of a cutting tool precisely by propagating an acoustic emission (AE) wave generated in case of abnormality occurrence from the cutting tool itself to a plate member through liquid or a liquid body. CONSTITUTION:A bush 11 penetrating the shaft part of a drill which is fitted freely attachably and detachably to a machine tool and driven to rotate is provided to the center part of the plate member 10 capable of propagating an AE wave. The internal diameter of the bush 11 is larger than the external diameter of the drill and the liquid or liquid body such as an oil film and grease can stay between the inner peripheral surface of the bush 11 and the outer peripheral surface of the drill while the shaft of the drill is run through the bush. Further, rod insertion holes 13 for fitting the plate member 10 to the machine tool are provided on the right and left sides of the bush 11. An AE sensor 9 is only mounted on an installation part 14 to attract a magnet case 15 to the member 10. Consequently, the AE wave propagated almost linearly from the drill 5 is detected, so there is neither noises nor attenuation originating a bearing and precise high-S/N detection is possible.

Title: Laser equipment
Inventor: YASUI KIMIHARU
IPC: H01S3/034
Filed: 1987-09-03
Abstract: PURPOSE:To lead out a high quality laser beam wherein the ratio of the inner diameter to the outer diameter of a ring type beam (M-value) is approximately infinite, by arranging a phase compensating mirror in a resonator or outside the laser beam exit side of the resonator, the mirror cancelling the phase difference between a laser beam passing through a magnifying mirror and a laser beam passing through the periphery of the mirror. CONSTITUTION:A collimating mirror 1 and the reflecting film 20 of a convex mirror 4 constitute a so-called unstable type resonator. A laser beam 7 reflected and magnified by the reflecting film 20 of a convex mirror 4 is amplified by laser medium 3, and collimated in a parallel beam by a collimating mirror 1, which is lead out as a laser beam 8 from the convex mirror 4 to the outside. This laser beam 8 is constituted of a part 70 passing through a partial reflecting film 20 and a part 71 passing through a non-reflection coating film 5. The phase difference between them is compensated by a phase compensating mirror 9, and a solid equi-phase laser beam 8 is lead out to the outside. Since this laser beam is solid, M-value is equivalent to infinity.

Title: Image reader
Inventor: HONMA TSUYOSHI
IPC: H04N1/403
Filed: 1986-09-22
Abstract: PURPOSE:To attain a stable binarization without fail by deciding a threshold from the black and white peak values of a picture signal and setting the lower limit of said threshold that can cope with said white peak position. CONSTITUTION:A data W-PK about the white peak values of previous eight lines including a current one is stored in a memory. Data Iying eight line before is updated for the unit of the line. Next, data obtained from a black peak detection circuit 111 is stored as a black peak value B-PK in the memory. The intermediate value between the determined white peak value of the current line and an inputted black peak value is obtained to decide on the slice level S of the next line. If the slice level is lower than a prescribed one, the lower limit 18 is modified. Thus the threshold can appropriately cope with the dynamic fluctuation of a picture and character on the original and its base density, thereby executing a precise binarization.

Title: Air flowmeter
Inventor: KAJIWARA YASUNARI
IPC: G01F1/32
Filed: 1982-12-16
Abstract: PURPOSE:To prevent the effect of noise by arranging an optical fiber on the downstream of a column provided in an air duct to measure a Karman voltex as modulated light. CONSTITUTION:Air flowing through an air duct 1 generates a Karman voltex 4 with a column 2 and a pressure difference is produced between the inside and outside of the voltex. The Karman voltex causes a microbending in a optical fiber 3 as passing near the fiber 3. This changes the propagation loss of light passing through the optical fiber to make light entering from one end thereof 3 reach the other end thereof being modulated in the intensity due to the Karman voltex 4. The modulated light is detected with a photo detector such as photo diode and photo transistor to set the number of Karman voltexes. As the light passing through the optical fiber won't be affected by electric or magnetic noise, the flowmeter is protected from malfunctioning by noise even when arranged near the engine of an automobile.

Title: Inverter device
Inventor: SUZUKI SHIGESADA
IPC: H05B41/24
Filed: 1989-08-29
Abstract: PURPOSE:To protect a circuit element by detecting a high voltage surge by a surge detector, and reducing the base current of a switching transistor. CONSTITUTION:A switching transistor 29 is switched with a high frequency to generate a high frequency voltage in the secondary winding 30s of an inverter transformer 30, thereby starting to light a discharge lamp 35. When a high voltage surge is inputted from the exterior, the surge is absorbed by a varistor 22, attenuated by noise preventing circuits 23-25, and outputted to the output terminal of a rectifier 26. This voltage waveform is still held at a high level, and applied to a constant-voltage diode 48 through a resistor 47. A base voltage to be applied to the base of a transistor 44 becomes high only during the conducting period of the diode 48, currents flowing to resistors 45, 46 are reduced during the period to lower the base voltage of a transistor 38, thereby decreasing the base current of the transistor 29 of an inverter 28.
