Filed: 1982-12-06
Abstract: PURPOSE:To cool molds efficiently and to improve the operating ratio of a molding machine by atomizing refrigerant such as water etc., spraying it to a molding machine for granulated expandable resin and cooling the molds by the use of heat of vaporization of the refrigerant. CONSTITUTION:When air is supplied to a blast pipe 11 under pressure and water is supplied to a water supply pipe 12, the water in the water supply pipe 12 reaches the support member 15 of a nozzle 10 and flows from a water supply chamber 17 into a water supply passage 13 of the nozzle 10. On the other hand, the air forcedly supplied from the blast pipe 11 flows into the air passage 14 of the nozzle 10 through a blast chamber 16 in the support member 15 and blows out of a nozzle tip 18. At this time, the water in the water supply passage 13 is sucked by the air flow blowing out of the nozzle tip 18, scattered from the tip 18 in the form of mist and the atomized water is sprayed to a male and a female mold 1, 2. In this manner, when molds are cooled by the heat of vaporization of water, 1kg of water can remove a quantity of heat of 540kcal from the molds.

Title: Production of multi plastic optical fiber formed body
Inventor: TOYOSHIMA SHINICHI
IPC: G02B6/04
Filed: 1994-09-07
Abstract: PURPOSE: To obtain an optical fiber molded body with little pixel defects in which little space is produced among optical fibers by filling a die with lots of multicore plastic optical fibers with a sheath resin having a low refractive index which fills the space among the fiber cores, heating the fibers at a temp. higher than the glass transition temp. of the core resin while reducing the pressure to remove gas, and adding tightening force to weld the fibers. CONSTITUTION: The multicore plastic optical fiber is produced by bundling lots of small core fibers having <=0.15mm diameter and comprising a transparent core resin with a high refractive index, and filling the space among the core fibers with a sheath resin having a low refractive index so that each core fiber is individually separated from others. Lots of the multicore plastic optical fibers thus obtd. are bundled to fill a die. The pressure in the die is reduced to remove gas such as air present in the space among the optical fibers, while the fibers are heated at a higher temp. than the glass transition temp. Tg of the optical fiber and tightening force to tighten the optical fibers in the die is added to weld. Usually, by gradually increasing the temp. of the whole die from Tg to a higher temp. by 10 to 90 deg.C, fibers begin to fuse and stick to each other.

Title: Acoustic echo canceler
Inventor: JOFU HIROO
IPC: H04B3/23
Filed: 1993-08-30
Abstract: PURPOSE:To suppress an acoustic echo generated in a sound conference device or a video conference device. CONSTITUTION:This acoustic echo canceler is constituted of a false echo signal generated means 11 having an adaptive digital filter, a subtracting means 12 for calculating a residual echo, a band removing filter 14 for removing a specific band signal in a call signal transmitted from a distant terminal side, a band pass filter 15 for extracting a specific band signal in an acoustic echo signal including a near terminal side sound, and a double talking state detecting means 16. The power of a specific band signal in an acoustic echo signal is calculated and a double talking state is detected in accordance with a change in the power, therefore troubles such as the generation of deterioration in characteristics and the generation of unpleasant noise due to the malfunction of a tap coefficient updating means are not generated even immediately after the detection of the double talk state.

Title: Output buffer circuit
Inventor: KAWANA KEIICHI
IPC: H03K19/0185
Filed: 1986-09-12
Abstract: PURPOSE:To contrive to decrease the tilt of an output waveform when an output voltage approaches a power terminal voltage by providing a series field effect transistor (TR) controlled by an output terminal voltage in series with an inverter made up of a field effect TR. CONSTITUTION:When a voltage at an input 4 changes from a low to a high potential, a voltage at an output terminal 5 changes from a high to a low potential. At the point of time when a voltage at the terminal 5 decreases and reaches a threshold voltage VTHN of an N-channel MOS field effect TR 6, the conductance of the said TR 6 decreases rapidly and the voltage at the terminal 5 is made stable to the threshold voltage VTHN of the TR 6. Thus, the tilt is decreased in the voltage trailing edge waveform at the terminal 5 toward the low potential as shown in figure and the production of an undesired radiation radio wave is less. Moreover, since the output waveform is changed rapidly up to a prescribed voltage, the reduction in the operating speed is small.

Abstract: PURPOSE:To keep a secret so that the person himself or the third party will not be able to know the number after conversion by converting the number by a scramble circuit including the stored number beforehand or the number by the number switching operation. CONSTITUTION:By pressing down a calling switch 15 and a converting switch 18 in the normal dial originating operation, the number which is stored in a memory 4 is read as it stands from the memory 4 to a control part 2 when a switch 132 for one subscriber out of a subscriber's selecting switch group 13 is pressed down, and the number data are converted by the equation of y=f(x) function through a scramble circuit 7. Here, the (x) is the number datum before conversion and the (y) is the number datum after the conversion. The number data after conversion are converted to dial signals by a dial signal circuit 6, and are transmitted to a switching circuit 9 and a line terminal 10. Concerning the dial originating by the number switching operation after the dial originating operation by the converting switch 18, the number is converted in the same way, and is transmitted as the dial signal.

Title: Pressure and differential pressure transmitter
Inventor: SAWA TAKAO
IPC: G01L13/02
Filed: 1985-09-30
Abstract: PURPOSE:To improve airtightness and liquid tightness of the inside of a pressure receiving diaphragm and to improve linearity of the deflection quantity of the pressure receiving diaphragm with respect to the pressure and especially to improve sensitivity of a low pressure area by forming a low melting point alloy layer on a joint at least of the surface of the pressure receiving diaphragm. CONSTITUTION:Either of a metal-metalloid system and a metal-metal system is proper as an amolphous alloy constituting the pressure receiving diaphragm 30. Since the joint with the casing at the surface of the pressure receiving diaphragm 30 is its peripheral part 30a, the low melting point alloy layer is formed at this area. Material of the low melting point layer is not limited especially and for instance, the ordinary solder material can be used. Further, it is needless to say that a melting point of a low melting point alloy is lower than the crystallization temperature of the amolphous alloy to be used but if the melting point is too low, the joining strength is lowered and for instance, the alloy with the melting point over about 140 deg.C is preferable.
