Title: Manufacture of magnetic bubble memory element
Inventor: TOCHIGI YOSHINORI
IPC: G11C11/14
Filed: 1985-06-24
Abstract: PURPOSE:To facilitate film thickness control due to further etching by implanting ions to a region forming a soft magnetic thin film transfer line while increasing the etching rate than other region in making the region forming the soft magnetic thin film transfer line of a magnetic bubble crystal thinner than the region forming the ion implantation transfer line. CONSTITUTION:As a mask 4 to apply ion implantation to a region (etched part 3) forming a soft magnetic thin film transfer line of a magnetic bubble crystal 2, a resist and Cu-Au are used for patterning. Then ions 5 are implanted to form an ion implantation layer 6. Then chemical etching is applied by phosphoric acid or hydrofluoric acid. In this case, the etching rate of the part of the magnetic bubble crystal 2 subjected to ion implantation is larger than that not subjected to ion implantation and since the mask 4 is used as a mask for this process, only an ion implantation layer 6 is removed by etching. Then the mask 4 is removed. Thus, etching is attained accurately and easily by the film thickness in response to the ion implantation energy.

Title: Ntsc color composite video signal processor
Inventor: TAKAHASHI HIROSHI
IPC: H04N9/00
Filed: 1979-10-22
Abstract: PURPOSE:To perform interpolation less in required characteristics and phase displacement without using a luminance/chromaticity separating circuit by interpolating position information and horizontal phase information of a composite video signal in direct and by coincide position information on luminance with that on chromaticity. CONSTITUTION:This processor consists of 1H delay lines 200 and 400, BPF100, adders 10 and 12, and subtracter 11. Then, a time lag for one subcarrier period is denoted as Z. In this case, signals supplied to adder 10 and subtracter 11 has a 1H time lag and while an output obtained by interpolating center parts of two adjacent lines appears at the addition output, the chromaticity signal is inverted in phase by 180 deg.C, so that it will seldom appear at the addition output. At the subtracter output, on the other hand, the luminance signal seldom appears. This addition output and subtraction output are mixed by adder 12 via BPF100. As a result, the time lag from the input to the output to the chromaticity signal component is 227-228 times the subcarrier period and in the digital system using a sampling frequency greater than the subcarrier frequency by several times, the phase displacement of of the chromaticity component never appears.

Title: Positive polarity arc welding device
Inventor: EGURI SHIGEO
IPC: B23K9/073
Filed: 1981-08-31
Abstract: PURPOSE:To suppress the generation of spatters in the short circuiting and to suppress the electric current during the period of arc generation in a correct range by providing a series circuit of a diode and a resistor connected to a reverse polarity with respect to an applied voltage in parallel with a reactor. CONSTITUTION:If driving rollers 6 are revolved by driving a motor 7 under application of a DC voltage between a wire 4 and base materials 5 and the wire 4 is fed toward the materials 5, welding electric current flows simultaneously with short circuiting between the wire 4 and the materials 4. In the stage of short circuiting, the electric current rises according to the rising characteristics determined by the resistance values of a reactor 3 and wiring cables. Right after the generation of the arc, electric current flows through the reactor 3 and arc load 8 and also through a variable resistor 10 and a diode 9 in parallel with the same; therefore, the fall of the electric current in the arc period is fast. Thus it is possible to make the rise of the welding current gentle by increasing the value of the reactor 3 so as to decrease the generation of spatters and to allow said current to fall sharply by bypassing the current to the resistor 10 and the diode 9 so as to decrease the size of welding diameter at desired value.

Abstract: PURPOSE:To discriminate synchronization establishment of a received SS signal effectively by using a 2nd multiplier so as to multiply a received SS signal with a correlation signal between the received SS signal and a PN code series generated from a receiver side at a 1st multiplier, detecting the product output at a detector and inputting the result to a level discriminator. CONSTITUTION:The circuit is provided with a 2nd multiplier 15 which multiplies a received SS signal with a spread demodulation correlation signal subject to band limit filtering at a 1st filter 12 after being obtained by a 1st multiplier 10 and with a 2nd filter 16 applying band limit filtering to a product output of the 2nd multiplier 15 and sending the result to a detector 13. Then the 1st multiplier 10 takes correlation between the received SS signal and the PN code series generated from a receiver side and the 2nd multiplier 15 multiplies the result of correlation and the received SS signal to obtain a product output with a large level difference between that at the synchronization establishment and that at asynchronizing state. Thus, a detection output of the detector 13 detecting the product output is fed to a level discriminator 14, where whether or not the synchronization is established is discriminated.

IPC: H02J3/14
Filed: 1981-08-31
Abstract: To enable a consumer of electrical energy to effect control of total energy consumption by various individual appliances and loads, each individual load has a control unit, conveniently in a plug top, which responds to pulses broadcast on the power supply wiring in the form of short duration interruptions of the waveform. At each appliance a microprocessor unit counts the number of successive pulses in a predetermined time interval and operates an electronic switch if the received count reaches a predetermined number, which may be different for different loads thereby enabling selective control of the loads. Provision is made for automatic restoration of supply if the overall energy consumption falls. Provision can also be made for automatic resumption of supply after a predetermined time interval.
