Title: Manufacturing method of sterilized vessels for preservation
Inventor: OOHIRA TAKEO
IPC: A61J1/10
Filed: 1978-04-28
Abstract: PURPOSE:To provide vessels suitable for long period preservation of blood or the like by utilizing  unbridged state thermo-plastic resin film having predetermined conditions and effecting heat seal  under the condition that the film is maintained by an outer layer of heat-resistive synthetic resin  film. CONSTITUTION:An inner layer of a vessel is made of thermoplastic resin film, such as polyethylene, ionomer resin and the like, capable of heat seal at an temperature under 200 deg.C, bridging by  applying an amount of radioactive ray within 2.5- 50Mrad and having heat-resisting effect, while  an outer layer is made of synthetic resin of polyester and polyamide having melting point of about  200 deg.C and heat- resistibility such that it will never be melted and decomposed at the temperature  below 200 deg.C, and receiving no effect such as degrading and the like by an amount of radioactive ray applied for the inner layer. A laminated sheet is made by adherring both of the above-described inner and outer layers and a vessel body is made by effecting heat seal for the periphery of the body at the temperature below 200 deg.C. An allowable amount of radioactive ray is applied for the  vessel body in air or inactive gas circumstance and thereby the inner layer is bridged, given with heat- resistibility and sterilized at the same time.

Inventor: BURAIAN II ATSUTOUTSUDO
IPC: H03F3/38
Filed: 1990-03-02
Abstract: PURPOSE: To reduce the cost and the size by exciting two stereo channels by means of a single isolation transformer and a primary reference oscillator. CONSTITUTION: In a stereo amplifier provided with channels A, B at a secondary power side, the channels A, B have a similar configuration to each other. For example, in the channel A, an output from a secondary winding 54 with a tap of an isolation transformer 46 is switched at a phase angle controlled with respect to a reference square wave received from a primary oscillator 80 by MOSFETs 56, 58. Secondary windings 60, 62 of a torus magnetic circuit 64 provided with a primary winding excited by a control circuit 76 via a buffer amplifier 68 control the MOSFETs 56, 58 respectively and outputs of the MOSFETs 56, 58 are combined at a node 70 and the resulting signal is fed to a loudspeaker 74 via a low pass filter circuit network 7. Thus, the configuration is simplified and the size is made small.

Title: Effective value conversion circuit
Inventor: SUGIHARA YOSHINOBU
IPC: G01R19/02
Filed: 1986-03-10
Abstract: PURPOSE:To decrease errors even in a low-frequency region and to shorten the time for settling by setting the frequency at the zero point of the transfer function of a low-pass filter at the frequency higher than either frequency of two real number poles. CONSTITUTION:A square-logarithm conversion circuit 10 converts input current Vi to the voltage V proportional to the logarithm of the square value thereof. The output voltage of the low-pass filter 40 is logarithmically converted and is applied to an arithmetic circuit 20, by which the voltage E0 is subtracted from the voltage V and the DC voltage E0 proportional to the effective value is outputted from an output terminal OUT. The transfer function of the low-pass filter 40 has the two real number poles P1, P2 and one zero point Z and therefore, the ripples at the same time constant of CR can be decreased as compared to the primary low-pass filter. The frequency at the zero point Z is selected at the value higher than the frequency of the real number pole P2 of the higher frequency and the lower than the frequency of 5 times the frequency of the P2 and therefore, the errors in the low-frequency region are decreased.

Title: Transmitting and receiving device
Inventor: SAKAMOTO KAZUO
IPC: H04N5/00
Filed: 1982-03-30
Abstract: PURPOSE:To ensure the stable transmission for a unidirectional transmitting/ receiving device, by transmitting the reception confirming information to a transmitter by making use of a part of the output of a local oscillator of a receiver, and receiving the output by the transmitter by applying AGC to the transmitter. CONSTITUTION:The output of a transmitting part 101 is transmitted from an antenna 6 through a transmitting/receiving device 5. While the reception confirming information received at the antenna 6 is branched by the device 5 to be led to a converter 7 for frequency of reception confirming information and then converted into an intermediate frequency by a local oscillator 8 at a receiving part 102. This signal undergoes amplification, filtering and wave detection and applies an AGC to an amplifier 2. The output of a local oscillator 15 of a receiving end office 20 is reflected by an impedance controller 14 and sent to a receiving frequency converter 17. However a part of the output of the oscillator 15 passes through the controller 14 and is transmitted to a transmitting end office through an antenna 13. Thus it is possible to transmit a carrier wave of a frequency which is nearly equal to the transmitting frequency of a transmitter 12 from the receiver 20 to said transmitter 12 without adding any transmitting function to the receiver 20. The transmitter 12 is applied AGC by this reception confirming information.

Title: Signal processing unit
Inventor: WADA RIYOUICHI
IPC: H03G3/00
Filed: 1979-04-26
Abstract: PURPOSE:To make it possible to use a simple-constitution operation unit by expressing an output signal with an input signal and the contribution rate related to it and by calculating the contribution rate and the output signal separately. CONSTITUTION:After input and latched in input interface circuits 1-4, audio signal inputs S1-S4 are divided successively through scanner 5 in respect to time  and are input to multiplier 6. Multiplier 6 multiplies input signals S1-S4 and the  contribution rate for the output of each input signal, which is output successively  onto the contribution rate signal line, and outputs multiplication results to accumulator 7. Accumulator 7 accumulates this multiplication output four times and outputs output signals OL and OR through output interface circuits 8 and 9. That is, scanner 5 is circulated once to multiply successively contribution rates R1-R4 and input signals, and output signal OL is formed by accumulator 7, and similarly, respective  input signals and contribution rates R5-R8 are multiplied, and multiplication results are accumulated to output output signal OR. Consequently, a simple-constitution operating unit can be used for this operation.

Title: Method and device for controlling electric power source for pulse arc welding
Inventor: NAGASAKA MORITOSHI
IPC: B23K9/09
Filed: 1981-04-06
Abstract: PURPOSE:To perform always stable spray transfer despite the fluctuations in external conditions in pulse arc welding by terminating the pulse current period after the prescribed time from the point of the time when the momentary value of pulse currents exceeds a reference value. CONSTITUTION:When a pulse frequency controlling circuit 14 outputs signals at prescribed periods, a pulse signal generating circuit 17 produces an output tp from the rise time of said signals. Then, a driving circuit 6 conducts a switching element 2' and supplies the output of a DC electric power source for pulses to  weld zones. This pulse current is detected with a detecting circuit 11, and is compared with the set value Ix of a reference current setter 12. When the pulse  current attains i >= Ix, a comparator 13 emits an output which starts the timing  of a time limiting circuit 15. Upon timing out of the circuit 15 after the prescribed time, the circuit 17 stops outputting. As a result the element 2' is interrupted, and the pulse current has the time range necessary for stable spray  transfer.

SOLUTION: When the building unit is assembled by weld joining each of pre-processed bar members and/or plate members (ceiling plates 1, flooring plates 2, front wall members 3, a rear wall member 4) using a building unit assembling device 5, either a specific assembling plan is chosen from many assembling plans information stored in a computer 59 or a specific assembling plan is input into the computer 59, and a characteristic value (length, width, thickness of the plate and others) of above each member is input the sensors 57, 58 before the weld joining procession, and input the value into the computer 59 so as to collate and confirm if the values fit with the specific assembling plan. The weld join processing is then followed.  Each of the plate members 1, 2, 3, 4 is welded at its given point by a spot welding machine 55 at the weld join operation position (where a movable frame 53 is positioned).
