Patent JP-H07307815-A (JP)
Title: Feeder
Inventor: ARITA KAORU
IPC: H04M19/00
Filed: 1994-05-12
Abstract: PURPOSE:To obtain a feeder capable of being integrated into a semiconductor integrated circuit in which crosstalk to adjacent subscriber lines is suppressed at polarity inversion and the size of the feeder is made small as a whole like a chip. CONSTITUTION:The flowing direction of a speech current from a current feeder circuit including transistors(TRs) Q1, Q2 to subscriber lines L1, L2 depends on the switching of PNPN switches Sl-S4. In the case of the switching (polarity inversion), after the speech current from the current feeder circuit is once transited to zero gradually, the polarity is inverted while outputs from the TRs Q1, Q2 are interrupted, and the current gradually restores to a state in the non-polarity inversion from zero. When the PNPN switches S1-S4 are adopted for the polarity inversion switches, the feeder is formed with a small chip and the entire feeder is integrated into an integrated circuit.

Title: Edger rolling method
Inventor: KOKUBO ICHIRO
IPC: B21B1/38
Filed: 1985-05-08
Abstract: PURPOSE:To improve the width accuracy and yield of a product by inclining vertical rolls toward the side opposite to the progressing direction of a rolling material, lifting slightly both side ends of the rolling material and subjecting the material to cross reduction rolling. CONSTITUTION:Expanded diameter parts 4 are provided to the lower side of a pair of the vertical rolls 3 and are integrally molded with inclined parts 5 in continuation thereof. The vertical rolls 3 are disposed to the perpendicular plane by inclining the same at an adequate angle in the direction opposite to the progressing direction of the rolling material S. The top end of the parts 5 is made higher than the top surface of a table roller 2 and the bottom end thereof is positioned at the same level as the pass line of the material S or below the same. Both end sides of the material S are thereby slightly lifted and the material is subjected to cross reduction rolling in this state and is supported by the roller table 2. The deformation projecting toward the lower side of the material S is thus made easy and the large width reduction is made possible without buckling. The width accuracy and yield of the rolling material are thus improved.

Abstract: PURPOSE:To prevent damage of an output circuit when an inverter pump is locked, by stopping production of output from the output circuit when it is detected that the voltage between the drain and the source of an MOS type field- effect transistor (MOS FET) is higher than a prescribed value. CONSTITUTION:An inverter circuit for an inverter pump of this invention is composed of a DC power source 1, a switching circuit 2, an output circuit 3 having switches of MOS type field-effect transistors (called hereinafter MOS FET), an AC motor 4 and a stop circuit 6 which detects the voltage drop VDS between the drain and the source of an MOS FET 3h in synchronism with energization of the MOS FET 3h and gives a signal to the switching circuit 2 to stop the output of the output circuit 3 when it is detected that the voltage drop VDS is greater than a prescribed value. With such an arrangement, MOS FETs in the output circuit 3 can be protected against burn-out even if the inverter pump is used under unexpectedly unfavorable conditions.

Abstract: PURPOSE:To elute perfectly core alloy in a short time by switching over the frequency to the specified frequency and carrying out high frequency induction heating when low melting point alloy is used for a core and the core alloy is eluted after resin molding. CONSTITUTION:When core alloy is eluted after molding in the resin molding method in which low melting point alloy is used for a core, the frequency is switched over from 1-20kHz to 50-200kHz and high frequency induction heating is carried out.

Further, a heat medium tank is provided in a high frequency induction heating coil and said coil is immersed in the heat medium tank in order to eliminate the alloy remaining in a molded product, or the heat medium is constant temperature circulated and the alloy is eluted therein. If the shape of alloy is hard to be eluted, the molded product is vibrated to elute quickly and perfectly.

Title: Device for digitally controlling shutter speed of camera
Inventor: UCHITOI MASANORI
IPC: G03B7/08
Filed: 1982-06-10
Abstract: PURPOSE:To realize the control of manual second-time which permits errors of a set signal in both positive and negative directions, by constituting a manual shutter second-time information resistance so that analog signals of prescribed decimal stages are outputted under overlapped conditions. CONSTITUTION:A relation, V=Vr(10-TV)/10+4Vr/80, is set between a fixed voltage Vr impressed upon a shutter second-time information resistance and a voltage V corresponding to a manually set shutter second-time, and bits (Q4-Q6) of integer stages obtained after the voltage V is AD-converted are used for the shutter speed control. Therefore, even when the error of the voltage V is in a stage of -4/8-+3/8 when a manually set shutter second-time is 1/500, the control is accurately performed. When the 2nd term (overlap signal) of right- hand member of the voltage V setting formula does not exist, accurate control is performed for an error in positive direction, but inaccurate control is performed for an error in the negative direction.

Title: Production of vinyl chloride-based resin
Inventor: MORIYAMA YOSHIHIRO
IPC: C08F6/10
Filed: 1991-04-03
Abstract: PURPOSE:To obtain the subject resin by polymerizing vinyl chloride, etc., in a polymerizer equipped with a reflux condenser installed on the outside thereof, recovering the unpolymerized monomers refluxing from the aforementioned reflux condenser in a recovering vessel provided on the outside of the polymerizer and reducing the time of reusing the unpolymerized substances and cost. CONSTITUTION:A polymerizer 1 additionally equipped with a reflux condenser 2 is charged with partially saponified polyvinyl alcohol which is a dispersing agent, tert- butyl peroxyneodecanate that is a polymerization initiator and vinyl chloride alone or a mixture of the vinyl chloride with other monomers copolymerizable therewith in ion exchange water and polymerization is initiated at 67.5 deg.C temperature. When the polymerization conversion rate attains 3%, the reflux condenser 2 is operated to advance the polymerizing reaction. When the internal pressure of the polymerizer 1 is lowered, an inlet valve for cooling water of the reflux condenser 2 is fully opened to feed the unpolymerized monomers to the reflux condenser 2. The resultant liquefied monomers are then recovered in a recovering vessel 3 additionally installed on the outside of the polymerizer 1. Thereby, the time required to recover the unpolymerized monomers is remarkably shortened to afford the objective vinyl chloride-based resin.

Abstract: PURPOSE: To obtain an inverter unit in which the size is reduced principally through surface connection circuit elements and the waveform of output voltage is not distorted even if an inverter transformer employing a manganese ferrite core is employed. CONSTITUTION: Not only an earth pattern but also conductor patterns 2, 3, 4 are not formed at the position (i) on a board 1 where the core of an inverter transformer comes into contact or approaches very closely.

With such arrangement, the stray capacitance causing distortion of the output voltage does not form a resonance circuit with any winding of the inverter transformer.

Abstract: PURPOSE:To enable light steering, by rotatably supporting the rear part of an oscillatable propeller shaft in a propulsion case, and by supporting this propulsion case to a driving case via an elevating unit and a steering unit. CONSTITUTION:A propulsion case 6 is supported around the outer circumference of a propeller shaft 7 via bearings, and is made to be oscillatable making the bearing 22 between an output shaft 5 and the propeller shaft 7 as the center of oscillation. The front end of the propeller shaft 7 is connected to the output shaft 5 via a universal joint 23, and on the rear end thereof a propeller 10 is screwed in. And, at the time of running, the propulsion case 6 is moved up and down by the expansion and contraction of an elevating cylinder 8, and is moved right and left by the expansion and contraction of a steering cylinder 9 to steer a boat. Accordingly, the propeller 10 can be set rearward without elongating the length of the propeller shaft 7, so that the frictional resistance of ship's bottom can be reduced. Further, since the lateral movement of the propeller 10 at the time of steering is small, light steering can be enables.
