Title: Tip position detecting method for coil
Inventor: FUJIYAMA AKITAKA
IPC: G01B11/00
Filed: 1986-02-04
Abstract: PURPOSE:To accurately and automatically detect the position of a nonlinear coil tip part by irradiating a coil with a light beam from slantingly above, forming a shadow which has a difference in brightness at a step part on the surface, and picking up and processing its image. CONSTITUTION:When the coil 1 is irradiated with extremely intense light from a lighting system 16, the shadow due to the step of the outer peripheral surface of the coil 1 is formed. An image of the irradiated coil 1 is picked up by a camera 17, whose image signal is A/D-converter 18. Then, one image plane is divided into several picture elements and image digital signals corresponding to the respective picture elements are outputted from the converter 18 and stored in a storage part 20 by the picture elements. Then, the coil is rotated by one circumference through a cradle 2 and its data is recorded 20. Then, a computing element 21 performs OR operation between an operator of edge emphasis and the stored image signal of one screen. The result is subjected to binarization process and the binary image of the step part is displayed 22. Then, unnecessary image data is erased to obtain image data on only the coil tip part. This is subjected to binarization process to detect the tip position as a picture element number.

IPC: B63H5/07
Filed: 1984-02-10
Abstract: PURPOSE:To try for a better propulsion efficiency by installing a bossing at the stern of the main hull with an inclination in the direction opposite to the direction of the main propeller revolution in the case of forward movement of a ship with respect to the hull center section, thus creating an eddy within the propeller surface in the direction opposite thereto. CONSTITUTION:A bossing 4 is installed at the stern of the main hull 3 with an inclination in the direction opposite to that of the propeller revolution in the case of forward motion of a ship with respect to the hull center section (C). By letting the bossing 4 and the hull 3 have a specific relation between each other to create an opposite eddy within the propeller surface, the hull resistance can be reduced and propulsion efficiency can be improved. At the same time, the vibration of the hull caused by revolving propeller can be lowered and the cavitation and accompanying corrosion can be prevented.

Title: Fm modulated brightness signal processing circuit
Inventor: KANEMOTO YOSHITAKA
IPC: G11B20/06
Filed: 1990-02-02
Abstract: PURPOSE:To process an inversion preventing signal without deteriorating the SN ratio, waveform characteristic and frequency characteristic of a demodulated signal by switching two inversion preventing circuits in accordance with the level of an FM modulated brightness signal. CONSTITUTION:When the level of an FM modulated brightness signal applied from an HPF 4 is higher than -6dB, a dropout detector 5 switches the contact (c) of a change-over switch SW1 to the 1st inversion detecting circuit K1 side and switches the contact (f) of a change-over switch SW2 to the equalizer 17 side. When the signal level from the HPF 4 is -6 to -12dB, the detector 5 switches the contact (c) to the 2nd inversion preventing circuit K2 side and holds the contact (f) on the equalizer 17 side. In the case of less than -12dB, the detector 5 holds the contact (c) on the circuit K2 side and switches the contact (f) to the 1H delay circuit 11 side. Consequently, a reproducing signal can be prevented from being whitened without deteriorating the SN ratio or the like of a reproduced brightness signal.

Title: Magnetic recording carrier
Inventor: ISHIWADA MASAMITSU
IPC: G11B5/72
Filed: 1983-02-18
Abstract: PURPOSE:To maintain favorable characteristics such as high magnetic flux density peculiar to pure iron for a long term by applying coating material contg. pure iron powder as the principal component on a substrate to form a metallic film and by coating the film with an oxidation inhibiting protective film showing its sufficient effect for a long term. CONSTITUTION:A magnetic film 2 is formed on a nonmagnetic disk substrate 1, and an oxidation inhibiting protective film 3 of cobalt-coated gamma-ferrite whose coercive force is almost equal to that of metal is formed on the film 2 with a spinner. Since the protective film is made of iron oxide, it has high resistance to the air and shows sufficient power to protect the metallic magnetic film from oxidation, and the value of a writing current for the protective film is equal to that for the magnetic film, so the protective film is optimum. The protective film may be made of other material. For example, a protective film of aluminum chelate can prevent passivation corrosion due to brine, etc. and has high wear resistance because it is made of aluminum oxide, and the film exerts no influence on the output magnetic flux from metal.

IPC: H01L21/8226
Filed: 1979-03-02
Abstract: PURPOSE:To equalize the writing threshold current of a semiconductor integrated circuit device and prevent the integrity of the device from lowering by arranging dummy injector having an area selected at the end of a memory cell array. CONSTITUTION:Dummy cells DCa, DCb are provided at both ends of an array of memory cells CEL1-CELn in such a manner that the injector area is selected larger than the memory cell. When the injector area of the dummy cell is suitably selected, the injector current of the memory cell CEL1 at the end becomes less than that of the memory cell CEL2 to equalize the writing threshold current of the memory cell array. Since the dummy cell can be formed smaller in size than the memory cell, it can prevent the integrity of the device from lowering.
