Title: Information reading-out system for disk storage device
Inventor: MIYASHITA TAKASHI
IPC: G11B19/04
Filed: 1987-04-09
Abstract: PURPOSE:To perform reading error correction with a high probability even if a reading error is produced due to an operational error, etc., of a mechanical system, by providing a head position displacing means separately from a head position controlling means and finely displacing a head in multiple stages within a desired extent. CONSTITUTION:The position of a carriage 4 is controlled by means of the position controlling means 20, actuator means 10, etc., of the processor 9 of a disk storage device 100 and a head 3 is positioned to a desired reference position of a disk 1. When a reading error is produced through a read/write circuit 5 under such condition, the head position displacing means 40 of the processor 9 is actuated by means of an off-track detecting circuit 22a, etc., and the head 3 is successively finely off-track displaced in the positive or negative direction within a prescribed extent. This displacement is continued until 'no reading error' is detected. Therefore, even when a reading error is produced due to an operational error, etc., of a mechanical system, reading error correction is performed with a high probability.

Title: Microorganism-catching agent
Inventor: ITABASHI OSAMU
IPC: A01N43/40
Filed: 1988-04-08
Abstract: PURPOSE:To provide a microorganism-catching agent having excellent mechanical strength, adsorptivity and expansion-contraction resistance, by comprising the composite of a particulate substance with an insoluble polymer having pyridinium groups prepared by quaternizing a composite material which is produced by coating the surface of the particulate substrate with a specific copolymer. CONSTITUTION:A microorganism-catching agent comprises the composite of a particulate substance with an insoluble polymeric compound having pyridinium groups which is obtained by quaternizing a composite material produced by coating the surface of the particulate substrate with a copolymer of vinyl pyridine with a crosslinkable divinyl monomer. Since the miroorganism-catching agent has a small volume change due to a gelation swell in water and an extremely large mechanical strength, the agent is hardly decomposed by operations such as stirring and shaking and can be dispersed in water to effectively contact with the microorganisms. The agent is suitable for column treatments because the agent has also a large surface area and is rigid. Further, in the case of the removal of plant pathogenic bacteria in soils, the agent has many advantages such as easy dispersing due to the particulate state and ready kneading with the soils.

Title: Sensitivity correcting method for external appearance inspection device
Inventor: TANAKA KIKUO
IPC: G11B5/84
Filed: 1994-04-26
Abstract: PURPOSE:To correct detecting sensitivity, and stably detect a defect by finding a correction signal from a displacement quantity by comparing an input light quantity of reflected light of an object found by an optional picture element of a selected CCD sensor with a preset basic light receiving quantity. CONSTITUTION:A light source 2 is lighted by a control device 4, and an image of reflected light of a layered plate being an inspection object 1 is picked up by a CCD camera 3. When a defect exists on a surface of the object 1, irregular reflection is caused by the defect, and is put on an input level remarkably different from the periphery. This is converted by an A/D converter 7, and is sent to a control signal operation means 5. The means 5 compares this with a preset basic input light quantity, and performs operation on a difference between them, and calculates a correction signal, and sends it to the device 4, and and controls a quantity of light of the light source 2. The means 5 also calculates a correction signal to change a preset value (for example, a threshold value) to discriminate a nondefective from a defect. In this way, the defect can be reliably detected by the preset value according to an input image.

Filed: 1989-04-07
Abstract: PURPOSE:To uniformly inject fluid sufficiently long in a longitudinal direction by providing a pair of notches so as to part and deviate equidistantly in opposite directions in parallel and providing a projection at the center of the blind inner peripheral surface between the notches. CONSTITUTION:Since discharge ports 3, 3 are provided with a pair of notches 2, 2 in parallel with the outer peripheral surface in the bottom side of a circular conical shape, the fluid injected therefrom is injected straight in parallel as it is on both end sides in the direction along an orthogonal plane S2.

As a result, the fluid injection distribution compounded and combined with the fluids injected from discharge ports 3, 3 in the central part and the fluid injection distribution on both end sides in the orthogonal plane direction are uniformalized and the injection distribution uniform over the entire central part and both end sides is attained.

Title: Separate lubrication device for outboard motor
Inventor: MATSUMOTO KUNIYOSHI
IPC: F16N39/00
Filed: 1983-05-23
Abstract: PURPOSE:To prevent a lifting pump from operating by mistake, by detecting the inclination of the body of an outboard motor to stop the operation of the pump under a prescribed inclination, regardless of the signal of an oil level detector. CONSTITUTION:A lubricating oil tank 26 is attached to an outboard motor body 16 which is supported so that it can be swung from a normal position nearly about a horizontal axis, relative to a hull 11. Lubricating oil is supplied from the tank 26 to the intake manifold 18 of an engine 17 by a pump 28. An oil level detector 36 is provided in the tank 26 to operate a lifting pump 23 by the signal of the detector to pump the lubricating oil up from a main tank 22 to the tank 26 to keep the amount of the oil in the tank 26 constant. When the outboard motor body 16 is inclined beyond a prescribed degree, the mercury 60 in the housing 59 of an inclination switch 58 comes into contact with both terminals 61A, 61B to electrically connect them to each other. For this reason, even if the oil level detector 36 is in operation, the lifting pump 23 is kept stopped, to prevent the oil from overflowing the tank 26.

Filed: 1987-04-11
Abstract: PURPOSE:To effectively record and reproduce by defining a result obtained by multiplying and adding the summation of a bit corresponding to the hamming distance of an adjacent level to a corrected hamming distance to constitute a 8-9 MHD converting encoding system and encoding a video signal. CONSTITUTION:The hamming distance in the conventional PCM code is improved, even in the same hamming distance, a large difference in an influence due to the weight of a bit is noticed to consider the hamming distance between respective levels by applying the weight and obtain an optimum encoding system by the use of the corrected hamming distance at the time of constituting a proposed encoding system. At the time of 8 bits, the encoding system is constituted according to the encoding rule of a 8-9 NRZ WI. Since this applies the encoding system for making the corrected hamming distance minimum, the small hamming distance, a small Tmax, a high reflection factor or the like are obtained to various waveforms. If such an encoding system is used, the PCM video signal can be effectively recorded and reproduced to completely display the merit of the PCM.
