Title: Magnetic head slider
Inventor: AGARI KOJI
IPC: G11B21/21
Filed: 1994-03-15
Abstract: PURPOSE:To obtain a magnetic head slider for a magnetic disc apparatus with which a cohesion when a disc is at rest and a friction when the disc is rubbed with a low speed are suppressed at low levels and stabilize a floating height when the head is made to float. CONSTITUTION:An electromagnetic transducer 7 is formed on the flow-out end 3 of a slider 1 and spherical protrusions 5a-5e are provided on the front part and the rear part of the flat surface 4 on the floating surface 2 side of the slider 1 bilateral-symmetrically. A pressure distribution in an air-flow direction (x) is such that a pressure rises sharply with a distance from the flow-out end 6 of the slider 1 to reach its peak near the crest planes 50c and 50d of the protrusions 5c and 5d and, after it falls sharply, reaches its peak again near the crest planes 50a and 50b of the protrusions 5a and 5b. A floating height is stabilized by this pressure distribution. When a disc is at rest or rubbed with a low speed, the slider 1 is supported above the disc surface by the small circular crest planes 50a-50e. Therefore, the cohesion and the friction can be suppressed.

Title: Collecting device for histogram data of original picture
Inventor: NOMURA AKIHIRO
IPC: G06T7/00
Filed: 1989-02-25
Abstract: PURPOSE:To use an inexpensive CPU by reading an image and without allowing a CPU to interpose directly for a histogram collection processing of its picture element data. CONSTITUTION:When read which runs along a main scanning line goes into a different image area of an original picture, a pair of data is read out of a register circuit 23 by a timing control circuit 25. Area discrimination data latched by a latch circuit 24 gives a first address of a memory 21, and a memory block corresponding to the area is designated. On the other hand, picture element data inputted synchronously with a picture element clock gives a second address of the memory 21, and a prescribed address in the memory block is designated. A counter circuit 26 counts the picture element block, shows a fact that data of the picture element which is being read at present is that in the area in the course of counting, and adding circuit 30 executes an access to the prescribed address and adds a prescribed value to the read-out contents, and a result is written in the same address by the timing control circuit 25, and the storage contents are updated. In such a way, an inexpensive CPU can be used.

Title: Oil leakage detector for underground tank
Inventor: MATSUMURA HIROSHI
IPC: B65D90/50
Filed: 1989-02-23
Abstract: PURPOSE:To permit a precise leaky oil detection even in the case of the oil small in evaporative power or a small amount of vapor or when water invades into a detecting pipe by providing an oil detector floating on the water in a gas detecting pipe buried near an underground tank and raised to near the ground surface and connecting the same with an indicating means by a stretchable wire. CONSTITUTION:When the oil leaks from an underground tank 5 into the surrounding underground, this leaky oil enters through a small hole 8a into an outer pipe 7a of a gas detecting pipe 6 and then through a gap A and a small hole 8b into an inner pipe 7b. In this case, since a float 9 and an indicator 15 located above are connected by a stretchable wire 18, this stretched wire 18 creates no hindrance to the positioning of the float 9 and an oil sensor 10 on the bottom of the inner pipe 7b. The oil thus entering into the inner tube 7b is allowed to flow through a small hole 19a formed on a plate 19 into the float 9 for penetration into the oil sensor 10 therein. In doing so, a carbon- containing swelling rubber forming the oil sensor 10 becomes swollen to change its electric resistance value, as a result of which the indicator 15 using a light emitting diode(LED), etc., is lighted.

Title: Crystal defect measuring apparatus and method
Inventor: KOMURO HITOSHI
IPC: G01N21/47
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To fetch target signals without being affected by signals besides the target signals and improve the efficiency of defect analysis by forming two or more detection systems for one wavelength value and storing the peak intensities of light rays with respective wavelength only in the case all of the detected scattered light intensity values exceed the set thresholds. SOLUTION: Scattered light rays 2 from a defect are converged by an objective lens 3, the light rays with wavelength of 810 nm and 532 nm are separated by a dichroic mirror 4, and further the resultant light rays are divided by spectroscopic mirrors 50, 60 for every wavelength and detected by photodetectors 12, 22, 52, 62. The detected signals are respectively amplified, the signal components derived from other than the scattered light rays from the defect are attenuated or eliminated by band-pass filters 14, 24, 54, 64, and the resultant signals are compared with previously set detection thresholds by respective comparators 15, 25, 55, 65. In the case signals of both comparators 15, 55 or both comparators 25, 65 exceed the detection thresholds, a OR circuit 5 transmits an instruction to both peak hold circuits 16, 26 to hold the signals.

Title: Video signal recording and reproducing system
Inventor: NAGASHIMA YOSHITAKE
IPC: H04N5/95
Filed: 1987-02-27
Abstract: PURPOSE:To obtain a time base signal having a correct time position and a good S/N, while an interchangeability between a customary system is maintained as well by recording a video signal after superimposing the code of a strong autocorrelativity on it, and forming the time base reference signal by means of giving a convolution operation to the code, at the time of a reproduction. CONSTITUTION:A burker code generation circuit 14 receives a timing signal from a previous step, and generates the burker code of n=7, for instance, during a horizontal synchronizing period, and it is recorded, being superimposed on the video signal. In a reproducing system, a code detection circuit 36 detects the burker code of the horizontal synchronizing period from a demodulated signal. A convolution circuit 38 gives the convolution operation to the detected code signal. By the above-mentioned operation, an impulse, having an amplitude of n-time and the S/N of n-times, is formed. The output of the circuit 38 is used as the time reference signal by impressing it to a time base correction circuit 34. Because the time position of the output of the circuit 38 is extremely correct, in the circuit 34, the time base error of the reproduced signal can be detected by a high precision, in cooperation with the good S/N, and also the time base correction in the circuit 34 comes highly precise.

When the optional number of light emitting times (x) is set by the light emitting times setting means 22, the maximum number of light emitting capable times (n) and the set number of light emitting times (x) are compared in the means 21. When the number of times (x) is larger, the number of light emission controlling times of the light emission control means 23 is set at the number of times (n), and when the number of times (x) is smaller, the light emission controlling times by the means 23 is set at the number of times (x). Thus, the number of light emitting times while performing exposure once is freely set in a state where the maximum number of light emitting capable times is taken as an upper limit.
