Title: Preparation of thermoplastic resin foamed molding in mold
Inventor: KUWABARA HIDEKI
IPC: B29K105/04
Filed: 1986-03-14
Abstract: PURPOSE:To obtain an excellent foamed molding without any complicated curing process even when prefoamed particles of insufficient foamability are used by pressing and cooling the foamed molding having been heat-foamed by filling thermoplastic resin prefoamed particles in a mold with an inorganic gas. CONSTITUTION:As the base resin or thermoplastic resin prefoamed particles, polyolefine resins can be used. The thermoplastic resin prefoamed particles can be prepared by foaming foamable resin particles containing a foaming agent in a pressure container under pressure. The prefoamed particles are filled into a mold and heated to be foamed and molded. A steam whose gauge pressure is 2-5kg/cm<2> is used for heating the prefoamed particles. The molding obtained by heating and foaming the prefoamed particles in a mold is pressed with an inorganic gas. The gas contained in the molding is prevented from going out while the molding is cooled down and the shrinkage of the molding can be avoided by pressing the gas into the molding. The pressure of the inorganic gas consisting mainly of nitrogen is usually about 0.01-5kg/cm<2>.G.

Title: Phase synchronizing circuit
Inventor: ASHIDA AKIRA
IPC: H04L7/033
Filed: 1981-04-17
Abstract: PURPOSE: To enable a circuit to follow up the frequency of an input signl by calculating the mean period of the input signal by counting a clock signal, and then dividing the frequency of the clock singal according to the mean period.  
     CONSTITUTION: When an input signal is inputted to a terminal, a phase information extractor 2 outputs differential pulses corresponding to the prescribed phase of the input signal. A counter 3 counts the differential pulses and sends out an output pulse at every N periods of the input signal, thereby resetting counters 4 and 5, and a memory 6. A counter 4, on the other hand, sends out an output pulse every time an N-number of output clock pulses from an oscillator 8 are counted, and this output pulse is counted by a counter 5 to store the memory 6 with the number of clock pulses which corresponds to the mean period of the input signal. A counter 7 divides the frequency of the clock pulses by the value stored in the memory 6 and outputs the result. A phase comparator 9 and an up- down counter 10 perform phase comparison between the input signal and output signal to send a phase correction signal to the counter 7.

Title: Treatment of electro-optical single crystal substrate and production of electro-optical parts
Inventor: KAWAGUCHI TATSUO
IPC: C30B19/02
Filed: 1994-03-28
Abstract: PURPOSE:To improve the crystallinity of an electro-optical single crystal substrate and to form a single crystal film having good crystallinity on this substrate by bringing the substrate into contact with a melt of an equilibrium state contg. solute and molten medium. CONSTITUTION:The melt 4 used in a liquid phase epitaxial method is held over a long period of time in the state of cooling the melt to a saturation temp. or below in a crucible 3 to allow a solid phase 5 to precipitate. The crystallinity near the worked surface is improved if the electro-optical single crystal substrate 2 of which the worked surface is brought into contact with the melt 4 in the solid-liquid equilibrium state is taken out of the melt 4. The electro-optical single crystal substrate is similarly treated even with the melt of an unsatd. state, by which the damage of the worked surface is ameliorated and the crystallinity is improved. Further, at least the worked surface of the electro-optical single crystal substrate is brought into contact with the melt of the solid-liquid equilibrium state, by which the crystallinity is reformed. The liquid phase of the melt is then put into a supercooled state, by which the single crystal film smaller in half-value width of an X-ray locking curve than the electro-optical single crystal substrate is formed on the worked surface side having the reformed crystallinity.

Abstract: PURPOSE:To obtain a binary image obtained by separating an object image properly from its background by utilizing a video signal corresponding to a specific part of an image to be binary-coded for a threshold for binary coding and selecting the specific part as a part to be supposed as the background. CONSTITUTION:A video signal outputted from an image pickup device 1 is amplified by an amplifier 2 and sent to a comparator 3 and a smoothing circuit 9, which smoothes the video signal to remove noise or the like and sends the smoothed video signal to a sample holding circuit 11. An address signal outputted from an address generating circuit 8 for specifying an address of an image memory 7 in synchronism with the video signal is also supplied to an address detecting circuit 10. At the time of the address coincides with a previously specified address, a timing signal is sent to the circuit 11, which holds the video signal outputted from the circuit 9 and sends the held video signal to an adder 12. The adder 12 adds the inputted video signal to a bias value obtained from a bias setting circuit 4 and sends the added value to the comparator 3. The comparator 3 compares the added value with the signal directly sent from the amplifier 2 to attain binary coding.

Title: Orthogonal modulating method
Inventor: TANAKA YASUHIDE
IPC: H04B1/10
Filed: 1994-03-29
Abstract: PURPOSE:To prevent the degradation of modulation precision from being generated even when a modulation output is returned to the side of a local oscillator in an orthogonal modulator and the cross modulation of the local oscillation signal by the modulation output is generated as a result. CONSTITUTION:The base band signal of a frequency fBB is multiplied by the sub-carrier of a frequency fLO 2. An orthogonal modulation is performed for the local signal of a frequency fLO 1 by the obtained sub-carrier multiplication base band signal and a modulation output of frequencies fLO1+fLO2+fBP are obtained. If this modulation output is returned to a VCO 201 via an orthogonal modulator 202 and a third intermodulation wave is generated by the cross modulation with a local signal, the frequencies fLO1-fLO2-fBB and 2fLO1+ fLO2+fBB of this third intermodulation wave become the frequencies belonging to the frequency band which is apart from the modulation output if the fLO2 to be used in the sub-carrier is sufficiently higher than the fBB that a base band signal uses. By eliminating these frequencies by a BPF203, an orthogonal modulation wave is generated without generating the degradation of modulation accuracy.

Title: Method and device for detecting scream
Inventor: YOKOO AKIHIKO
IPC: G08B23/00
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To detect a scream from noises by judging an abnormal state when the sound volume of 1st frequency width is decreased and the sound volume of 2nd frequency width is increased. SOLUTION: When the scream is generated in any abnormal state, this is picked up by a microphone 1 for collecting surrounding sounds at all times, amplified by an amplifier 2 and inputted later to a discriminator 4 after its voice frequency is separated by a frequency separator 3. Then, prescribed high and low frequencies for recognizing the scream are set to the discriminator 4, and the device 4 compares respective input levels with a reference value for each prescribed band. In this case, the prescribed high frequency area is the band to remarkably appear when the voice of that scream is spectrum- analyzed and the prescribed low frequency area is the band to appear when an ordinary voice is spectrum-analyzed.  Therefore, when the input level of that high frequency area exceeds the reference value on the high frequency area side concerning the inputted voice but the input level of that low frequency area does not exceed the reference value on the low frequency side, that voice is discriminated as the stream.
