Title: Noise reducing circuit
Inventor: YAMAGUCHI KOICHI
IPC: H03H17/02
Filed: 1994-03-10
Abstract: PURPOSE:To provide a satisfactory noise reducing effect for a moving image signal or a voice signal upon which a high frequency noise is superimposed. CONSTITUTION:A noise level detection circuit 14 detects a noise component at a line part, where there is no image signal, in the vertical blanking term of an input video signal, converts its level into a DC voltage and outputs it. The signal levels of E1 and E2 are decided by a voltage comparator circuit 15 and the identification signals of (+), (-) and '0' are provided. When the signal level of E1 is higher than that of E2 (E1>E2), a subtracted signal (E1-E3) is selected, in the inverse case of E1<E2, an added signal (E1+E3) is selected and when those signal levels are equal (E1=E2), the signal E1 is selected as it is by a selective addition/subtraction circuit 18.

Title: Shape modeling system
Inventor: AIZAWA TAMIO
IPC: G06F17/50
Filed: 1987-02-25
Abstract: PURPOSE:To obtain a solid shape modeling system where non-procedual element deletion is easy, by interchanging a deletion object element of a cell complex chain and the next generated element at the time of meeting a prescribed condition. CONSTITUTION:When an operator uses an input means 6 to indicate a pattern of the deletion object element of the cell complex chain displayed on a CRT 5 in the non-procedual deleting and generating operation (deleting operation of already inputted fundamental pattern elements), an arithmetic unit 7 is operated. Then, the deletion object element, the next generated element (the element generated following the deletion object element), and data of fundamental pattern elements related to this element are retrieved from data of the cell complex chain generated in a data base 3. Set operation and addition among these data are performed to update data of the deletion object element and the next generated element which are stored in the data base 3. This operation is successively repeated from the next generated element to the last generated element by the arithmetic unit 7, and finally, data of the deletion object element is deleted from the data base 3.

Title: Method and device for preparation of material and molding of low density composite product compounded with resin
Inventor: KOBAYASHI YUUKICHI
IPC: B27N3/08
Filed: 1982-03-15
Abstract: PURPOSE:To manufacture the product of the composite material which includes more wooden  powder than resin and can float on the water, by injecting a specified material into a mold,  reducing the pressure in the mold, thereby aiding the expansion of the resin. CONSTITUTION:The composite material is formed by compounding a wooden material and plastics. The weight of the wooden part is the same as or heavier than that of the plastics. The  specific gravity of the molded product is 1.0 or less. The specific gravity of the resin of the  composite material is 0.9 or less. Hydraulic fluid is supplied through a hydraulic fluid port 18  in advance, and a main rum 13 is advanced. Then a rod 9 is advanced and penetrated into a  thick part of a cavity 7, which is to become the product. The volume of the cavity 7 is made  smaller than normal. A fused material is injected from a spool 2 and the cavity 7 is filled.  When the pressure in a pressure generating chamber 14 is reduced, the rod 9 is moved back. Then the pressure in the cavity 7 in the mold is decreased and a vacuum state is locally obtained. Therefore the material is readily expanded locally. When a quick cooling medium 23 is  supplied to a quick cooling port 22, vacuum bubbles are generated in the inside, and the low  density is obtained. Then the perfectly hardened product is obtained after the cooling and  hardening time.

The transmitter (a) is successively shifted from the position P1 to the position P35 to obtain 630 data as a whole. The data of the same distance are 36 and, when a flaw (cavity part) is present on the line connecting both positions, the propagation time becomes long and has the correlation with the size of a flaw. If 36 propagation time data for equal distances are classified by magnitude, for example, in five stages, the flaw can be displayed by a size in five stages.

Abstract: PURPOSE:To provide an ignition timing controlling apparatus for an internal combustion engine, which is capable of preventing rough idling operation of the engine, by controlling the ignition timing on the basis of the difference between the mean value of the idling speed and the actual engine speed when the engine is being warmed up. CONSTITUTION:At a step 25, it is detected, for instance, from the temperature of engine cooling water whether an engine is being warmed up or not. If it is detected that warming-up of the engine is not completed, the mean engine speed Na is calculated at a step 29 and it is considered as an aimed engine speed NF during the while when the engine is being warmed up (step 30). Further, at a step 27, an ignition timing correcting value thetaIDL is calculated from the difference between the aimed engine speed NF and the actual engine speed NP. Thus, it is enabled to prevent occurrence of hunting of the engine speed during while when the engine is being warmed up.

Abstract: PURPOSE:To enhance coupling efficiency of both by fitting a glass ball into the recess provided to the tip of a lens which couples a semiconductor laser and an optical fiber. CONSTITUTION:A recess 6 is provided to the end face of a lens 4 for coupling a semiconductor laser 2 and an optical fiber 3 interposed therebetween, opposing to the laser, and a glass ball 5 is fitted in said recess 6 and is fixed by an adhesive 7.

Hence, at the outlet of said lens 4, the angle is made further smaller and such light enters the optical fiber 3. Hence, the light from the semiconductor laser enters the optical fiber without leaking to the outside and this enables coupling efficiency to be enhanced.

The reception discrete signal is separated alternately into two series one by one along the time series and positive/negative code conversions are applied alternately in the respective series by code converters 14, 15. Through the operation above, the orthogonal component and the in-phase component of the modulation wave as a base band signal are separated into two series. Further, the processing is executed by digital signal processing only. Thus, disadvantages such as troublesome phase adjustment realized in an analog circuit, level fluctuation or deterioration in characteristic depending on the sensitivity of components is dissolved entirely.
