Title: Manufacture of magnetic recording medium
Inventor: SUGITA RYUJI
IPC: G11B5/85
Filed: 1990-11-20
Abstract: PURPOSE:To obtain a magnetic tape having a high output in a short wavelength region by making the inclination to the normal of an evaporating surface of a straight line connecting the evaporating section of an evaporation source and an oxygen introducing-port nose larger than that of a straight line connecting the evaporating section and a shield plate when the magnetic layer of a Co group is formed to a moving substrate through vacuum deposition. CONSTITUTION:Oxygen is introduced into a vacuum tank from the evaporation completion section side by an oxygen introducing pipe 10. A shield plate 3 for shielding evaporated atoms is disposed between an oxygen introducing port and a substrate 1. The inclination theta1 to the normal 12 of an evaporating surface of a straight line 13 connecting the evaporating section 11 of an evaporation source 8 and an oxygen introducing-port nose is directed in the same direction to the normal 12 to an inclination theta2 to the normal 12 of a straight line 14 connecting the evaporating section 11 and the end section of the shield plate 13, and theta1>theta2 is set. Accordingly, oxygen concentration near the surface of a magnetic layer is lowered, and the film thickness of a non-magnetic layer is thinned extremely, thus reducing spacing loss at the time of recording- reproduction.

Title: Welding equipment provided with function for recording image of welding condition
Inventor: KAMO KAZUHIKO
IPC: B23K9/09
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To enable a clear image to be fetched by controlling a welding current so as to be a base current period successively to the rising from the least base current period and also fetching the image of a welding zone in the least base current period. SOLUTION: A controller 9 controls a welding current by controlling the power source 5 of electric welding, and also controls the fetch of the image data of a weld zone into an image processor 8 by controlling a video camera 7. Successively to the falling of the peak current period of the welding current, it becomes the least base current period in which the electric current value becomes even smaller than that of the base current period. The welding current is controlled to be a base current period successively to the rising from this least base current period; also, the function is so structured that the image of the weld zone in the least base current period is fetched into an image pickup means. Thus, the image processor 8 can fetch a clear image in which a molten pool is most grown.

Title: Camera
Inventor: MATSUSHIMA HIROSHI
IPC: G03B7/17
Filed: 1990-11-26
Abstract: PURPOSE:To conduct hand-deflection warnings respectively suited for normal photographing and stroboscope photographing time by differentiating a reference issuing the hand deflection warning between at the time of stroboscope photographing and at the time of normal photographing based on the use of natural light. CONSTITUTION:Lens data including a focal distance, a minimal reduced aperture, open increased aperture and auto-focus of a lens are inputted into a lens control circuit 2. A light measuring circuit 7 is made to perform its light measuring operation for a photographed object, and a light measurement output obtained therefrom is subjected to A/D conversion and thereby restricted to calculate a shutter speed. A first hand deflection warning reference value is determined on the basis of the focal distance of lens inputted and this reference value is compared with a shutter speed value calculated to decide whether or not this value falls under the 'hand deflection limit 1'. What value is below the 'hand deflection limit 1' means that the shutter speed value is smaller than the value corresponding to (1/focal distance of lens). Thus, a hand deflection warning circuit 10 is made to warn the hand deflection. Next, when a stroboscope is in a condition able to emit light, it is decided whether or not the shutter speed falls below the 'hand deflection limit 2'. In case of 'yes', warning of the hand deflection is conducted. That the shutter speed is below the 'hand deflection limit 2' means that the released shutter speed value is below the value corresponding to (1/focal distance + alpha).

When air-column speed at a the heat-recovery-chamber side and that at a combustion-chamber side are set high and low, respectively, the density difference in a medium is generated, the medium is moved below the bulkhead from the chamber with high density to that with low one, the medium in the heat recovery chamber is overflowed to the combustion-chamber side from the bulkhead, flow for pushing into the lower part of the heat recovery chamber is created, and medium circulation flow is generated. The entire medium can be circulated by the scattering plates even in the large-sized fluidized bed incinerator. By controlling the amount of air from the scattering pipe 9 immediately below the bulkhead 5, the amount of circulation of the medium can be controlled.

Title: Cylindrical grinding machine
Inventor: KONDO KUNIHIKO
IPC: B24B27/00
Filed: 1990-11-22
Abstract: PURPOSE:To obtain a work of a high work precision without forming slide marks in the work by providing electromagnets which are movable with movement of a grinding wheel in working at positions close to the grinding wheel at least on one side of it. CONSTITUTION:A cylindrical grinding machine comprises electromagnets 8 held by an electromagnet holding means 11 on both sides of a grinding wheel 1, and a magnetic force controlling means 9 for controlling a magnetic force of the electromagnets 8. Because the electromagnets 8 are held on a table 10 by the electromagnet holding means 11 at the time of work, they move integrally with the talbe 10 without changing the relative position to the grinding wheel 1. By adjusting a current value supplied to coils of the electromagnets 8 at this time, a pulling force to a work 6 toward the grinding wheel and a force of the grinding wheel 1 pushing the work 6 can be balanced to each other, so the work 6 can be prevented from warping without its getting in contact with the work surface of the work 6. A precision polishing work can thus be achieved without forming slide marks in the work 6.

Filed: 1989-12-11
Abstract: PURPOSE:To set the azimuth with high accuracy by providing the signal generating parts consisting of the ROMs which are controlled by the clock signals, the D/A converters, and the vector generators. CONSTITUTION:The bit patterns of desired waveforms stored in the ROM 1 and 2 are sequentially read out by the clock signals.

Abstract: PURPOSE:To simplify the assembling work by outputting a reference signal for recording current adjustment outputted from a reference signal generating circuit to a magnetic head instead of a recording signal. CONSTITUTION:An ATF (automatic track finding) signal generating circuit 74 divides the frequency of a channel clock signal CK to generate four reference signals having frequency bands fCH/72, fCH/18, fCH/12, and fCH/6 respectively.

That is, reference signal generating circuits 76 and 78 divide the frequency of the channel clock signal CK to output reference signals for recording current adjustment having frequency bands fCH/2 and fCH/4. Thus, the recording current is easily adjusted.
