Title: Antimicrobial agent for sandbox
Inventor: YAMAMOTO TATSUO
IPC: A01N59/06
Filed: 1994-09-14
Abstract: PURPOSE: To obtain an antimicrobial agent for a sandbox, having a high strength without eluting an active ingredient with rain, crushing and leaking and safe for use by infants or children by thermally forming a substance containing prescribed amounts or more of silicon oxide and silver at a prescribed temperature or above. CONSTITUTION: This antimicrobial agent for a sandbox is obtained by thermally forming a substance containing >=30wt.% silicon oxide and >0.5 wt.% silver as an active ingredient at >=120 deg.C temperature. For example, a powdery substance containing the silicon oxide is thrown in an aqueous solution of silver nitrate regulated to a prescribed concentration and the resultant mixture is stirred and filtered. The filtered substance is then washed with water and dried at about 90 deg.C. The particle size is regulated with a suitable sieve and the obtained particles are heat-treated at >=120 deg.C temperature to afford the antimicrobial agent for the sandbox.  The obtained antimicrobial agent is capable of stably suppressing the proliferation of microorganisms for a long period and further maintaining the sanitary sandbox without eluting the active ingredient with rain or crushing and leaking out due to a weak physical strength.

Title: Step-up converter
Inventor: ASANO SHOZO
IPC: H02M3/155
Filed: 1994-09-14
Abstract: PURPOSE: To stop the output from an output terminal, too, so as to prevent the malfunction of load connected to the output terminal, when a step-up converter is turned off, by connecting the second switching means to the output end of a smoothing means, and also, turning on the switching means in response to the output of an AC coupling means. CONSTITUTION: When a controller COT is turning on and off a switching element Q1 periodically, an inductance element L outputs boosted pulse voltage, and it is coupled with AC in a capacitor C2, and it turns on a transistor Tr through a rectifying circuit. Therefore, a switching circuit Q2 becomes conductive, and the voltage smoothed with a smoothing circuit is outputted from an output terminal OUT. On the other hand, when the ON/OFF control of the switching element Q1 by the controller COT is suspended, the output of the inductance element L becomes DC voltage inputted from an input terminal IN, so the switching element Q2 is turned off, and the outputs does not occur.

Title: Area measuring apparatus
Inventor: MORI NOBUHIKO
IPC: G01B11/28
Filed: 1983-11-24
Abstract: PURPOSE:To enable the accurate measurement of image information even when the number of picture elements contained in an objective region are few, by adding the number of picture elements in the objective region of a displayed image due to a contour line and the number of picture elements on the contour line based on the density difference of inside and outside picture elements. CONSTITUTION:Image information from a magnetic tape is stored in memory 2 and displayed by an image processing apparatus 3. When the joystick 5 and the button 6 of an operation disc 4 are operated while said display is observed, the position of the contour line in a region wanting to calculate an area is determined and a contour line 12 demarcating an objective region to image memory 8 is completed. When the point whithin this line 12 is indicated by the joystick 5, the number of picture elements in the objective region are counted by a paint-out circuit 9. Similarly, a picture element dividing and counting circuit 10 counts the number of picture elements on the contour line 12 on the basis of the densities of the inside and outside picture elements of the contour line 12 and the count values of the circuits 9, 10 are added by an adder circuit 11. By this system for counting even the number of picture elements on the contour line 12, the area of an image can be accurately measured even if the number of picture elements in the objective region are few.

SOLUTION: A solid-liq. stream sucked with a pump is made to flow into the rotary drum 3 being driven with a motor 2 from a solid-liq. inlet pipe 1 and turned in a radial direction by allowing the stream to collide with the uppermost step disk 4. Since splits are disposed radially at each disk 4, as a solid component gradually accumulates from the peripheral part, the flow passage area is reduced and the flow rate is increased. Then solid particles are collected in the vicinity of an inner wall of the rotary drum 3 and made to flow down and recovered in a solid particle recovering tank 12. On the other hand, the running water from which the solid particles are removed is allowed to flow out from a clear water outlet pipe 5.  At this time, washing liquid is fed into the rotary drum 3 from a pump for the sludge discharge device to wash away the sand and mud clogged at the disk 4 to prevent the clogging.

Title: Chrominance subcarrier noise suppressing circuit
Inventor: TAKEYA NOBUO
IPC: H04N9/64
Filed: 1990-08-24
Abstract: PURPOSE:To obtain the chrominance subcarrier noise suppressing circuit which prevents transient deterioration by varying filter characteristics as the band of a chrominance subcarrier becomes wide. CONSTITUTION:This circuit is equipped with plural delay circuits 1-4 which delay the chrominance subcarrier in a composite video signal by desired times, circuits 11, 12, and 31-33 which multiply their outputs and an input signal by certain coefficients and adds their outputs to obtain desired filter characteristics, and switch circuits 25 and 26 which switch their output signals. Then the delay circuit outputs and input signal is multiplied by the certain coefficients and the results are added to obtain the desired control characteristics, thereby controlling switch circuits 25 and 26. Namely, when the band of the chrominance subcarrier is narrow, the filter characteristics are narrowed down and when the band almost becomes wide, the band is switched to a band wider than the filter characteristics; when the band is very wide, the signal is outputted as it is. Consequently, while noises are suppressed, the chrominance subcarrier signal can be outputted while its transient is held at it is.

IPC: H04M1/60
Filed: 1998-08-05
Abstract: PROBLEM TO BE SOLVED: To attain multiple party speech and to allow the user to hear a voice clearly, even at a place with a large surrounding noise by controlling either or both of a speech by a headset employing an external receiver and an external microphone and a speech by a built-in receiver and a built-in microphone. SOLUTION: When a headset is inserted, since a detection switch 14 is open, an amplifier control section 16 discriminates insertion of the headset. Then whether or not a multiple party speech is set is discriminated, by discriminating whether or not a setting signal from an operation section 15 is stored in the amplifier control section 16. When the multiple party speech is set, the amplifier control section 16 activates a power supply for a built-in receiver amplifier 4, a built-in microphone 10, an external receiver amplifier 6 and an external microphone amplifier 12. As a result, plural users conduct speech with speech opposite parties at the same time, by using a built-in receiver 5, a built-in microphone 9, an external receiver 8 and an external microphone 11.

After that, a P type InP layer 303 is epitaxially grown, and, in addition, a P type InGaAsP layer 304, the so-called cap layer 304, is grown. The back surface of the N type InP substrate 301 is performed an etching in order to grow epitaxially a buffer layer. Then, a P type InP layer 305, which is subjected to become the base layer, is epitaxially grown. Impurities are selectively diffused or implanted on the base layer 305 for forming an emitter layer 306. In this case, as the emitter layer 306 becomes an N type, an npn transistor is formed in longitudinal type to a P clad layer 303, an active layer 302 and an N clad layer 301, by which the LD is constituted, because the substrate 301 and the base layer 305, which are subjected to become the collector layer, are an N type and a P type respectively.
