Title: Method and apparatus for detecting surface flaw of work
Inventor: HASHIMOTO KAZUNARI
IPC: G06T1/00
Filed: 1995-08-07
Abstract: PROBLEM TO BE SOLVED: To detect only flaws even when dust adheres to a surface of a work. SOLUTION: While a surface of a work 10 is illuminated by an illumination A, images are photographed by a CCD camera 14. Flaw candidates are detected based on the images. The detected candidates include those generated by a flaw and also those because of dust adhering to the surface of the work 10. The surface of the work 10 illuminated by an illumination B is photographed by the CCD camera 14. While the flaw decreases a brightness on the obtained image, the brightness is not lowered by the adhering dust. Therefore, only the flaw is selected/detected from the preliminarily detected candidates.

Filed: 1989-08-02
Abstract: PURPOSE:To eliminate adverse influence caused by a fixing unit and to obtain a compact constitution by forming optical elements with plastic and installing them on the opposite side to the fixing unit over a deflector. CONSTITUTION:The optical elements including a lens 24 leading laser beams scanned by the deflector 23 to a photosensitive body 1 and a mirror 26 are formed with plastic and installed on the opposite side to the fixing unit 13 over the deflector 23.

Title: Printing head
Inventor: OOYAMA SHIGERU
IPC: B41J2/28
Filed: 1986-08-28
Abstract: PURPOSE:To obtain a low noise printing head, by providing a magnetic circuit to a lever holding member and arranging a ferrite vibration damping material between said magnetic circuit and a base frame. CONSTITUTION:When voltage is applied to a piezoelectric element 1b at the time of printing, the piezoelectric element 1b abruptly replaces and a lever 2b displaces only at the central part thereof at first. When the lever 2b further generates displacement to be displaced in a predetermined quantity necessary for printing, the strain energy accumulated in the lever part becomes larger than the attraction force of a lever holding member 1d and the lever 2b is released from the lever holding member 1d at the tip to rotate around the acting point of the laminated type piezoelectric element 1b and the printing wire 5 contacting with the tip of the lever 2b is driven by predetermined quantity to freely fly and returns. The rebounding of the lever generated when the lever returns to collide with the piezoelectric element is attenuated by the attraction force of the lever holding member 1d. Since a ferrite vibration damping material 1h is arranged in order to prevent the transmission of the lever holding member 1d due to the collision of the lever to a base frame, noise due to the vibration caused by collision is reduced.

Filed: 1989-08-04
Abstract: PURPOSE:To surely control the address of a memory by obtaining a duplex memory address control circuit and applying the read addresses after checking the coincidence/discordance of these addresses together with the parity check. CONSTITUTION:The buffers 12a and 12b and the RAM 14a and 14b are formed into a duplex structure, and the read outputs are selected by selectors 18 and 26. The comparators 24 and 32 check the coincidence/discordance of those read outputs. Furthermore the parity check circuits 22 and 28 check the presence or absence of parity errors. Then the logic circuits LOG 20 and 30 operate the selectors 18 and 26 with the outputs of the comparators 24 and 32 and the circuits 22 and 28 to attain the necessary selecting operations. Thus the addresses read out of a memory 10 are applied or not according to the results of the comparators 24 and 32 and the circuits 22 and 28. As a result, two types of checks are carried out and the error detecting factor is improved. Then the address of the memory 10 is correctly controlled.

Title: Oil tight holding device for control valve
Inventor: TORII SATORU
IPC: F15B11/08
Filed: 1991-07-16
Abstract: PURPOSE:To produce a compact device at low cost by forming a poppet chamber into which a poppet is inserted on a main pressure oil passage on a control valve main body, and providing a plunger on a back side which opens/closes a bypass passage through a spring for a main spool and a lever plate arranged on the valve main body end face. CONSTITUTION:When a control valve 2 is set at a neutral position, a bottom side pressure in a hydraulic cylinder 1 having a load 53 is introduced into a poppet chamber 7 through a main pressure oil passage 6 and an oil passage of a poppet 8. Since a diameter of a bypass passage 11a is set very small, a diameter of a seat of a plunger 14 is also small. Accordingly, a force applied by a spring 21 for a main spool to the plunger 14 through a lever plate 20 gets larger than a force pressurizing the plunger 14 by the bottom side pressure. As a result, the seat is closed by the plunger 14, while a seat 26 is closed by the poppet 8 through the bottom side pressure, and thereby oil tightness is attained in a bottom side pressure in the hydraulic cylinder 1.

Title: Permanent magnet erasion head
Inventor: UENISHI MITSUAKI
IPC: G11B5/325
Filed: 1982-11-18
Abstract: PURPOSE:To eliminate the erasion noises due to the change of remaining magnetization by setting the surface roughness at <=0.1-S for the magnet part of the rubbing surface of a magnetic tape of a permanent magnet erasion head main body of a reducing alternating magnetic field type. CONSTITUTION:A magnetic tape 1 travels through magnetic poles 5, 6 and 7 respectively on a tape rubbing surface and receives successively magnetic fields 94, 95 and 96. Therefore the track of the tape 1 is saturated up to a point 90 regardless of its initial position on a B-H curve and finally produces the remaining magnetization shown by a point 93 after passing through points 91 and 92. As the surface roughness of the erasion head is kept at <=0.1-S, the erasing process is equal at all points on the track of the magnetic tape to be recorded and reproduced. Therefore the remaining magnetization that is finally generated at the point 93 has the same fixed value as each point on the track. Such remaining magnetization is not produced in the form of a reproduction output with a reproduction system where the reproduction output is equal to the differential value of a leaked magnetic flux of the tape. Thus no erasion noise is produced due to the change of remaining magnetization.
