Title: Crank angle detecting device of internal combustion engine
Inventor: OTSUKA IKU
IPC: F02D45/00
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To provide a crank angle detecting device not to be affected by the error in manufacture. SOLUTION: Teeth from 1 to 34 of a rotor 200 are arranged at the target distance 10 deg. (target angle is 30 deg. between the tooth 34 and the tooth 1), but the tooth 10 and the tooth 34 are deviated. Accordingly, the angles between three teeth to be set to measure the angle are normally 30 deg. from C1 to C12, however, those of C1 and C10 are large, and those of C2 and C9 are small. The passing time of respective angles between tooth are calculated on the basis of the generating intervals of signals of a crank position sensor 400 after fuel is cut and an engine is twice or more rotated. The value is compared with the theoretical time (not constant because the crank shaft is not uniformly rotated) of passage of respective tooth, corresponding to the rotational speed at that time, the deviation time is calculated, and the deviation amount of the angles between tooth are calculated.

Further, the circuit extending from the 1st trailing register R1 to a main memory 14 compresses and stores the redundant repetitious pattern in a run-length code. Thus, the input DATA signal 16 is processed by run-length encoding and the redundant repetitious pattern thereof is compressed to be stored in the main memory 14 compactly.

Title: Recording and reproducing apparatus
Inventor: KANEKAWA HIROSHI
IPC: G11B17/043
Filed: 1994-02-22
Abstract: PURPOSE:To obtain a recording and reproducing apparatus in which whether a disk case is inserted normally or erroneously is judged on the basis of information which has sensed the surface and the rear surface of the disk case at the upper part and the lower part of an insertion port, in which the disk case is pulled into only when it is inserted normally, whose costs are low, whose breakdown is small and which prevents the disk case from being inserted erroneously and damaged. CONSTITUTION:The reflection factor of a shutter 19 and a decorative plate 18 for a disk case 1 to be inserted is different from that of the surface part of the case 1, and a control circuit 13 detects a change in output voltages of sensors 10a, 10b. On the basis of the order of the change, the circuit 13 judges the insertion situation of the case 1. When it judges that the case has been inserted normally, it drives a motor 12, and it turns a roller 16 via a pulley 14 and a gear 15. Consequently, the case 1 is pulled into the inside. Inversely, when the circuit 13 judges that the case 1 has been inserted erroneously such as that the upper part and the lower part are reversed or that the front part and the rear part are reversed, it does not drive the motor 12, and it informs a user of the effect. Thereby, it is possible to obtain the recording and reproducing apparatus which enhances an assembly property, whose costs are low, whose breakdown is small and which can prevent the case 1 from being inserted erroneously and damaged.

Abstract: PURPOSE:To reduce the measuring error of an inclined magnetic field by accurately calculating a peak position by calculating the inclination of the phase of data obtained by applying Fourier transform to self-encode data and calculating the peak position from said inclination in the accuracy of a decimal point and below. CONSTITUTION:A static magnetic field is applied to an object 201 to be examined by a static magnetic field generator 202.

In the case of sequential photographing, an inclined magnetic field of a reverse code is applied in the same quantity as the self-encode quantity corresponding to a peak position 305. As mentioned above, by forming self-encode data 304 at every time to calculate the peak position 305 thereof, when the peak position observed when the self-encode quantity is 0 capable of knowing the quantity of the inclined magnetic field at each time is set to a standard, since the shift of a peak generated when there is the self-encoded quantity is proportional to the self-encode quantity, the self-encoded quantity can be known by investigating the peak shift of measured data.

Title: Method for erasing photomagnetic recording
Inventor: KATSUTA SHINICHI
IPC: G11B11/105
Filed: 1985-03-12
Abstract: PURPOSE:To eliminate residual recording component and to improve the erasure characteristic by selecting a spot diameter of an erasure laser beam formed on a recording medium larger than the spot diameter of the laser beam at recording and reproduction. CONSTITUTION:The diameter r' of the spot 4' of the erasure laser beam is selected to be larger than the diameter (r) of the spot 3 of the recording/ reproduction laser beam (r<r'). Thus, the width 41' of an erasure track is r' so as to cover a part 21' corresponding to the residual recording signal component 21 thereby offering sufficient erasure effect. As to the laser light source used for recording/reproduction/erasure of a photomagnetic disc, an He-Ne laser or a semiconductor laser is used and the aperture ratio of an objective lens used at recording and reproduction is 0.5-0.6. In using the beam for recording, a pit 2 corresponding to the beam diameter is formed. Thus, the residual signal component is eliminated and the diameter is changed by giving slight defocusing to a conventional beam and it is executed without using any new optical system.

Even when an Al-Si film 7 is vapor-deposited as a second wiring layer in 1.5 to 2.0mum, no disconnection is caused.

Title: Method and apparatus for slitting high temperature cast billet
Inventor: HIRAKAWA NORIO
IPC: B23D19/00
Filed: 1979-04-24
Abstract: PURPOSE:To make possible the efficient breakdown rolling, by pushing the cast billet being supported by four guide rollers into the breakdown mill, and by adjusting the position of the cast billet in the pass line with the lower roll elevator. CONSTITUTION:The center distances of guide rollers 11, 12, and guide rollers 10, 13, are arranged shorter than the initial length of the cast billet 6. The guide rollers 10, 13, are the idle rollers, whereas the guide rollers 11, 12, possess the driving force to indent the cast billet 6 at the circumferential speed faster than the circumferential speed of the rolling roll during the breakdown rolling, so that the ring type projection 1 effectively indents the cast billet 6. The breakdown mill 7 is internally provided with the upper roll 2 and the lower roll 3 respectively possessing one ring type projection 1. The lower roll 3 is provided with the elevator 20 to adjust the pass line of the cast billet 6. By thus adjusting the pass line of the cast billet 6, only single ring type projection 1, formed in each of upper and lower rolls 2, 3, at the same position makes possible the breakdown rolling.
