Title: Rorating speed controller
Inventor: GOSHIMA KENJI
IPC: H02P29/00
Filed: 1982-03-25
Abstract: PURPOSE:To improve time-voltage transducing sensitivity, by using a ramp generator for generating a ramp wave with a steep gradient only when intervals of inversion are greater than a specific value. CONSTITUTION:A pulse generator 17 is triggered by an output pulse C of a double-edge detecting circuit 13 to generate a pulse F with a specific pulse width. The ramp generating circuit 14 responds to the rise of the output pulse F to generate a ramp wave D and is reset in response to the fall of a next output pulse F. Consequently, the waveform of the ramp wave is very steep. Then the amplitude of each pulse is proportional to intervals of the inversion of a reproduced signal and its maximum amplitude (peak value) is the same with a conventional device. The peak value of this ramp wave is sent to a differential amplifier 6 to control the rotating speed of a motor 3.

IPC: H01L21/822
Filed: 1988-03-04
Abstract: PURPOSE:To reduce a leakage current of a high permittivity metal oxide used as a dielectric by adding a metal element, having a smaller number of positive charges even in an ionized state than that of the metal of a metal oxide film, to the film. CONSTITUTION:Different type metal 3 having smaller number of charges in an ionized state than that of constituent metal of a metal oxide film 2 having high permittivity used as a dielectric formed on a P-type Si semiconductor substrate 1 in a plane (100) is added in the film 2. Accordingly, doner generated by oxygen pores in the base metal oxide film 2 is compensated by different type metal acceptor, thereby reducing the electric conductivity of the film 2. Thus, it can reduce a leakage current, thereby obtaining a capacitor adapted for placing a VLSI chip or the like having a small area, a large capacity and a small leakage current.

Title: Multi-processing type delay circuit
Inventor: MORIMURA HIROSHI
IPC: H04J3/12
Filed: 1983-03-28
Abstract: PURPOSE:To obtain an economical multiplex digital signal delay circuit by holding the 1-frame preceding data through a selector until the count value of a multi-processing type counter reaches the set value and then delivering the input signal as it is when the said count value reaches the set value. CONSTITUTION:A multiplex digital signal Ii of a multiplex degree (n) is supplied to a level change detecting circuit 1. The circuit 1 checks the level change of an input signal Ii-1 preceding the signal Ii by a frame for each channel and delivers the detection signal Vi to a multi-processing type counter 2. The count value Ai of the counter 2 obtained for each channel is compared 3 with the delay set amount D set to a comparator 3. The comparator 3 delivers the control signal Ci of a low level to a selector 4 when Ai>D is satisfied. Then the selector 4 selects the signal Ii and delivers a signal Oi. A shift register 5 supplies the signal Oi-1 delayed precedingly by a frame to the selector 4 when the signal Oi is inputted. The selector 4 keeps the signal Oi-1 and delays it until the value Ai of the counter 2 reaches the set amount D. When the value Ai reaches the amount D, the selector 4 delivers the input signal as it is.

Title: Fluoroscopic apparatus for interior of parcel
Inventor: HIRAMA YUTAKA
IPC: G01V5/00
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To discover a suspicious object inside a parcel with case, by making an inspection stage loading the parcel movable in either of a right-left direction and an up-down direction. SOLUTION: A parcel is placed on a movable inspection stage 1C, and an operation switch is turned ON to project X rays from an X-ray tube. The X rays pass through the panel to reach an X-ray display part of an X-ray image- detecting part, whereby an X-ray display film is excited. In consequence, the X rays are efficiently converted to a fluorescent energy, forming an image. The image is reflected at a mirror 9, which is visually inspected by an inspector. The presence/absence of a suspicious object in the parcel is accordingly confirmed.  If the whole of the parcel cannot be reflected to the X-ray image- detecting part because of a size, a positional shift of the parcel, the inspector turns ON a right-left movement switch or an up-down movement switch installed at a lower main body 1B to move the movable inspection stage 1C by a first motor 16 in a right-left direction or up-down direction. A position of the parcel is changed through the right-left movement, while a size of the image is changed through the up-down movement. The suspicious object can be easily specified from the whole parcel.

Abstract: PURPOSE: To manufacture a dimensionally stable, three-dimensionally deformed, resin coated sheet-like textile material by arranging a core material between two coated layers coated on the inner surface by an adhesive material and applying a slight pressure to join them by the adhesive. CONSTITUTION: A laminate is formed by stacking a deep-draw formable textile material and a resin film one by one at an adequate order and the number of the textile material 1 depends on the strength of the manufactured core material. The textile sheet and the resin film are arranged such that the resin is uniformly penetrated into the textile sheet by applying heat in a deep-draw process, and preferably in the case of the relatively thick laminate the textile sheet and the resin film are arranged in alternate positions. The constitution of the laminate depends on the strength required in the three dimensionally deformed textile material and when it is used as a core material, a certain minimum compression strength should be provided.  A fabricated article is treated by a liquid or paste type adhesive and wetted beforehand by a solvent of the adhesive and/or a wetting agent so as to provide a high-strength sandwich structure by the adhesive jointed on the coated surface.
