Title: Terminal connecting method for synthetic resin made thick monofilament
Inventor: YAMADA HIROTOKU
IPC: B65H69/04
Filed: 1981-05-25
Abstract: PURPOSE:To obtain superior strength and satisfactorily durable connection by using a bundle piece. CONSTITUTION:The terminals 1 and 1' of each monofilament are inserted into bundle pieces 2 and 2' respectively. The terminals 1 and 1' are crossed with their mating terminals and then inserted back into the bundle pieces 2 and 2' in the opposite direction, thereby preducing loops 3 and 3' respectively. The monofilaments 4 and 4' on the longer side are then pulled so as to tighten the loops 3 and 3'. After that, the terminals 1 and 1' projected from the bundle pieces 2 and 2' are rotated and are inserted into the openings of the loops 3 and 3'. With this construction, the terminals 1 and 1' are tightly fixed in the loop openings. Therefore, superior connection strength and satisfactorily durable connection can be attained without loosening the connection, even if the tension between the monofilaments on the longer side are released.

Title: Controller for transformer
Inventor: KANBARA TAKASHI
IPC: H01F27/08
Filed: 1978-06-29
Abstract: PURPOSE: To accomplish the cooling safe operation of the transformer by means of an arithmetic circuit for generating the first signal proportional to the number of running transformers in a cooler unit and a comparator for comparing thereof with the second signal proportional to the actual load current.  
     CONSTITUTION: Signals a of running transformers are sent to an arithmetic circuit 17 from respective units. The circuit computes the actual number of running units and provides an analog output at level of transformer allowable load signal according to the results. On the other hand, the actual load R of the transformer is provided as an analog value with a power transducer. The two value are applied to a comparator 18. When it is a positive signal, an output ΔR is inputted to a relay 19 to start a cooler unit in standby, thereby increasing the cooling effect of the transformer. When the automatic starting the cooler unit fails or the transformer is in the total load operation, a signal C is produced by a control volume drive gear to reduce the load only by an amount allowed for the output ΔR.

Title: Turner of am/fm receiver
Inventor: WATANABE TOSHIHIKO
IPC: H03J5/00
Filed: 1984-04-20
Abstract: PURPOSE:To decrease the number of externally mounted components to an IC without any clock signal generating circuit especially by constituting an intermediate frequency transformer of an AM receiver with a switched capacitor filter and obtaining a clock signal driving the switched capacitor filter from a frequency signal of a PLL synthesizer. CONSTITUTION:A mixing circuit 23 mixes frequencies of a reception signal fo and a local signal fL and applies an intermediate frequency signal If of 455kHz in frequency to a band pass filter 25. The band pass filter 25 consists of a switched capacitor filter (SCF). Then clock signals phi, phi' of the SCF acting as the band pass filter 25 are obtained without any special generating means. That is, a reference frequency signal fref is fed to a frequency divider 26 and a prescaler 30 via a line l1. A frequency divider 26 and an inverter 27 applies frequency division to the reference frequency signal fref to obtain the clock signals phi, phi'. It is desirable that the frequency of the clock signals phi, phi' is in the relation of phi>455kHzX2, because the center frequency of the intermediate frequency signal is 455kHz and the frequency divider 26 is set to the frequency dividing ratio to satisfy this condition.

Title: Process for manufacturing electrode for sulfuric acid type fuel cell
Inventor: FURUYA CHOICHI
IPC: H01M4/88
Filed: 1987-03-31
Abstract: PURPOSE:To obtain an electrode with excellent output power characteristics by mixing reaction layer material powder, polverizing, adding a solvent to it to from a sheet, and letting platinum retain after polymerizing and rolling a gas supply layer whereby catalytic reaction proceeds actively even if the platinum amount is small. CONSTITUTION:Hydrophilic carbon black, hydrophobic carbon black and polytetrafluoroethylene are dry-mixed in mixer and pulverized. Next, a solvent is added to the reaction layer material powder to from a sheet having reaction layer. A gas supply layer is polymerized and rolled on the reaction layer, then platinum is retained in it. By the arrangement, the electrode is readily manufactured in a short time by simple devices and the aftertreatment is easy because no surfactants are used. Also, since platinum disperses uniformly adhering to only hydrophilic carbon black in the reaction layer, the electrolyte is in contact with all platinum in the reaction layer causing catalytic reaction actively and improving the output power.

IPC: H04R17/00
Filed: 1991-04-11
Abstract: PURPOSE:To decrease in cost by making small the dispersion of a frequency characteristic due to the opening area of an acoustic material and simplifying the fixing means of an acoustic resistance material. CONSTITUTION:A piezoelectric ceramic plate 12 is stuck to a metallic substrate 11, made into a piezoelectric diaphragm 13, and covered with cases 14 and 15. Into the space of the diaphragm 13 and a back case 15, a porous foam body 17 is sandwiched. The micro foam of the foam body 17 is utilized as an acoustic resistance, the resonance of the diaphragm 13 is damped, and the frequency characteristic is flattened. The acoustic resistance is determined by the opening area of leaking hole 15a of the case 15 and the dispersion of the frequency characteristic can be reduced. Since the foam body 17 is sandwiched only into hte space of the diaphragm 13 and the case 15, it is unnecessary to fix the acoustic resistance material. The decrease in cost can be performed.

Title: Received beam former
Inventor: TAKEUCHI YASUTO
IPC: G01N29/44
Filed: 1988-03-31
Abstract: PURPOSE:To simultaneously form further many received sonic lines so as to reduce the number of parts, therefore, to reduce power consumption, by converting the signal received by a vibrator element to a light signal and delaying said light signal by a optical fiber to convert the same to an electric signal to form sonic lines. CONSTITUTION:The ultrasonic signal received by a vibrator element IL0 is amplified by a preamplifier A0 and the output signal thereof allows a light emitting diode LED0 on an element side to emit light which is, in turn, transmitted to photodiodes PD by optical fibers OF0-OF127. In the same way, the received signal of an element EL63 allows a light emitting diode LED63 to emit light which is, in turn, transmitted to a photodiode PD0 on an output side by an optical fiber 63F0. The length of each of the optical fibers OF0-63F0 is controlled in order to delay a light signal so as to form one sonic line and the output signal of an amplifier A0' forms the 0-th sonic line and, in the same way, the output signal of an amplifier A127' forms the 127-th sonic line. By this method, the optical fibers F connecting the light emitting photodiodes LED and the photodiodes PD constitute a perfect group formation.
