Title: Servo circuit for optical disk player
Inventor: YOKOTA HACHIRO
IPC: G11B7/085
Filed: 1988-12-21
Abstract: PURPOSE:To prevent runaway of a pickup by giving a tracking error signal to a window comparator and using an output of the comparator so as to stop the supply of an output signal from a phase compensation output circuit to a servo circuit. CONSTITUTION:When an external disturbance such as vibration is exerted to a CD player while it reproduces a CD and a track jump takes place, a tracking error signal is outputted from an error signal generating circuit 18. The tracking error signal is inputted to the window comparator 23 and when the signal exceeds a prescribed level, an H level signal is outputted from the comparator 23. The output signal from the comparator 23 is inputted to a timing circuit 24, a switch 26 is turned on, no tracking servo signal is supplied to an LPF 21 and a feed motor 4 is stopped.

Title: Method and device for judging external shape of tire
Inventor: KOKUBU TAKAO
IPC: B60C19/00
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To specify defective concave and convex on the surface of a tire and, at the same time, to recognize the sizes of the concave and convex sections and judge the extents of the defects. SOLUTION: The direction, in which a light emitting section emits light toward a tire is different from the direction in which a light receiving section receives reflected light from the tire by an angle θ. Depending upon the raggedness variation of the surface of the tire, therefore, the height Δh of the tire from a reference plane varies and an offset amount Δd is produced in the radial direction of the tire between reflecting points (an actual reflecting point R on the surface of the tire and a virtual reflecting point V on a reference plane B). As a result, Δh=Δd/tanθholds.  Since the offset amount corresponds to the difference of the light receiving position of the light receiving section, the height variation h can be found easily by calculation from the above-mentioned equation when the proper light receiving position of the light receiving section is known.

Abstract: PURPOSE:To easily and rapidly discover a problem in software. CONSTITUTION:When a control part 6 controls the printing operation of a printing part 4 on the basis of the program stored in an ROM 7 corresponding to the printing data from a host interface 1, the task constituting the processing executed by the control part 6, is stored in the cue memory within an RAM 8 as trace data corresponding to the trace data control data inputted from a data input part 11. A predetermined quantity of trace data are totalized to be converted to the printing data corresponding to one page by a PDL conversion part 10 and this printing data is printed on recording paper in the printing part 4. By this constitution, it becomes unnecessary to perform theoretical simulation while visually observing the trace data arranged and displayed on the CPT screen of the host computer connected to a printer.

Title: Semiconductor device
Inventor: KIDA TOMOYUKI
IPC: H01L23/50
Filed: 1990-11-28
Abstract: PURPOSE:To contrive the improvement of the mounting density of a semiconductor device by a method wherein a plurality of outer leads are made to project from the bottom of a package and the outer leads are made to bend in such a way that the tip parts of the leads are positioned on the side on one side of the side surfaces, which are parallel to the directions of arrangement of the leads, of the package. CONSTITUTION:A semiconductor chip 11 is sealed in a package 10 in such a way that an element formation surface of the chip 11 is set at roughly 90 degrees to a mounting surface of the chip 11, that is, to the rear of the chip 11 and at the same time, leads 12 are made to project from the rear of the chip and are made to bend along the side surfaces of the package 10 into roughly a U-shaped form. Accordingly, the chips can be directly surface-mounted on a mounting board 17 and at the same time, it becomes possible to select either the surface mounting or a socket mounting conforming to needs and uses and while this advantage is held, an area to be required for mounting can be further reduced significantly. Thereby, even in the case the socket is mounted, the socket can be also reduced conforming to the area of the bottom of the package. As a result, the mounting density of a semiconductor device can be drastically improved.

Title: Grain steam knotting device
Inventor: KANEKO TATSUMI
IPC: A01D59/00
Filed: 1987-12-21
Abstract: PURPOSE:To maintain thread strength and to knot grain stems tightly and firmly without rusting a knotting part with excessive water, by twisting a ribbon shrinkable by wetting with water with a nonshrinkable ribbon to give a thread, wetting the thread with water before knotting and removing excessive water. CONSTITUTION:A nonshrinkable ribbon 36 such as jute which will not shrink even by wetting with water is blended with a shrinkable ribbon 37 such as highly shrinkable vinylon which will shrink by wetting with water in any ratio to give a twisted thread 35, which is wetted with water 45 when the thread is passed through a lower curved part 46 of an induction pipe attached to a knotting part. Since water drops are scattered in the surroundings and the knotting part is rusted when the ribbon 35 is excessively wetted, water is adjusted to proper water content by an excessive water removing device 47 consisting of a pair of rolls 48 at an outlet of a curved part 46 to knot grain stems. Since the thread shrinks while keeping given strength, the grain stems can be firmly knotted.

Abstract: PROBLEM TO BE SOLVED: To attain the preprocessing of digital video signals via a VLSI circuit before the compressing and encoding operations by storing all read/write memories used for different preprocessing functions into a single memory block. SOLUTION: A filter unit 20 works in parallel or series to the luminance and chrominance pixel data.
