IPC: G01R31/00
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetic wave resistance measuring device wherein not only electromagnetic wave resistance of an object is evaluated but a part of the object which is easily affected by radiation noise is specified. SOLUTION: A control device 4 allows a signal generator 5 to input the signal of appropriate input level and frequency which is suitable for testing a circuit board 1 into an input terminal of the circuit board 1. A stage 3 moves an antenna 2 to specified positions sequentially, and when the antenna 2 reaches a radiant point, it is allowed to radiate a specified electromagnetic wave. A signal measuring device 6, upon receiving the output signal of the circuit board 1 at electromagnetic wave radiation, measures presence of unwanted signal in a signal band, and if unwanted signal is present, signal/unwanted signal ratio is measured.  The electromagnetic wave resistance measuring device evaluates electromagnetic wave resistance of the circuit board 1 based on presence of unwanted signal in the signal band which is measured with the signal measuring device 6 and the signal/unwanted signal ratio.

Title: Ring oscillator
Inventor: NAKAJIMA TERUYA
IPC: H03K3/0231
Filed: 1995-06-05
Abstract: PURPOSE: To shorten the delay time of continuous delayed signals and also to increase the number of delayed signals without changing the oscillation frequency and the number of stages of an inverter contained in one loop of a rind oscillator and with the same control current/oscillation frequency characteristic kept as it is by connecting together the unit inverter circuits in an odd number of stages. CONSTITUTION: The serial circuits of P and N channel transistors are connected in parallel to each other, and a constant current source that is controlled by a current control circuit 9 is connected to the P and N channel sides of these parallel circuits respectively. Thus a unit inverter circuit 22 is obtained in such a constitution where two inverters use the constant current sources 2 and 3 in common to each other. Then such circuits 22 are connected together in a ring shape and continuously at (n) staves (n: an odd number). As a result, the delay time of every inverter stage is shortened and many clock signals can be taken out.

Filed: 1981-09-02
Abstract: PURPOSE:An oxymethylene copolymer with a specific melting point, heat weight retention and structure is formed, dispersed in water containing a basic substance and treated at a specific temperature to increase its heat weight retention, thus improving its heat stability. CONSTITUTION:For example, trioxane and ethylene oxide are used to form an oxymethylene copolymer that has a melting point over 150 deg.C, higher than 98% heat weight retention and -CH2O- units containing at least two adjacent carbon atoms in the major chain. The resultant copolymer is dispersed in water and/or an alcohol medium containing 10wt% of a basic substance such as an amine or ammonia and heated at 130-155 deg.C (it corresponds to the copolymer-swelling temperature range) to effect hydrolysis, thus increasing its heat weight retention over 99wt% to stabilize the copolymer. EFFECT:The resultant copolymer gives molded products with high stability as well as good physical properties.

IPC: B01D53/68
Filed: 1985-06-26
Abstract: PURPOSE:To make it possible to selectively take out reutilizable unreacted slaked lime, by separating collected ash consisting of the dust, unreacted slaked lime and reaction product contained in the stock gas of an incinerator on the basis of the difference between the sizes of particles after grinding. CONSTITUTION:The collected ash supplied by a collected ash feeder is sent to a classifying part by air from an air take-in port while receives grinding action by the rotation of the rotor 18 mounted to a shaft 17. At this time, because general dust contains an increased amount of a hard component and is markedly inferior to grinding property while slaked lime is easily ground into fine particles, said ash is separated into a fine powder and a coarse powder by the classifier 19 mounted to the shaft 17 and a powder containing an increased amount of slaked lime is issued to a fine powder outlet 20 and a powder containing a much amount of general dust is issued to a coarse powder outlet 21. The powder containing a large amount of unreacted slaked lime is recirculated to exhaust gas dust for the purpose of reutilization.

Title: Method and device for flatly correcting upper surface of packing bag piled together
Inventor: ODAWARA HIROYOSHI
IPC: B65B43/18
Filed: 1988-06-03
Abstract: PURPOSE:To increase a containing amount by piling together a bag on a soft cushion pillow, sealed with fluid, so as to form the upper surface into a plane, when many packing bags are piled together in a containing frame of an automatic packing machine or the like and taken out being sucked by a vacuum cup.
