Title: Magnetic alloy film having negative magnetization coefficient
Inventor: SAKAKIMA HIROSHI
IPC: H01F10/16
Filed: 1987-10-30
Abstract: PURPOSE:To obtain a magnetic alloy film having a large negative magnetization coefficient in a low magnetic field by stacking a Co layer of a specific thickness with Co as a main ingredient, and a Mn layer thinner than a Co layer with Mn as a main ingredient. CONSTITUTION:A multilayer film composed of Co and Mn is prepared on a silicon wafer substrate in a vacuum of 10<-9>Torr using an ultra-high vacuum dual evaporation apparatus. These films are expressed as (tCo, tMn)n, where tCo and tMn are the thickness (Angstrom ) of Co and Mn layers respectively, and (n) is the number of layers. When examined by the typical X-ray small-angle scattering using Fe-Kd of a stacked layer, a number of satellite peaks can be seen when the thickness of a layer is thick, forming a good lamination layer. And as the thickness of a layer becomes thinner, small-angle scattering peaks being observed decrease, forming a modified composition alloy film. Those that show an abnormal a magnetization curve is a Co/Mn lamination layer that satisfied tMn<30Angstrom  and tCo<tMn as shown by an O mark. Therefore, to obtain a large negative magnetization coefficient in a low magnetic region, it is necessary that the thickness of a Co layer be thinner than that of a Mn layer and less than 30Angstrom  which is the thickness of a Mn layer.

Title: Countermeasure circuit against flaw of optical disk reproducing device
Inventor: ITO TAKESHI
IPC: G11B7/09
Filed: 1984-12-28
Abstract: PURPOSE:To prevent track jump surely and strengthen against vibration by using an addition signal of a subbeam as a flaw detecting signal and changing the amount of current for generating saw tooth wave for PWM modulation according to the amount of drop-out. CONSTITUTION:Let it be supposed that reference voltage V0 is set to about 1/2 of peak value of a subbeam addition signal SBAD of normal state of reproduction. In the ordinary state, Vp>V0 and current does not flow in the collector of a transistor Q2, and consequently, current does not flow in an auxiliary current source 27 too. Supposing that drop-out occurred in the subbeam addition signal SBAD due to a flaw of a disk, and output Vp of a peak detecting circuit 25is changed, collector current of the transistor Q2 starts of flow gradually, and L2=(1/2) I0 is made to flow in the auxiliary current source 27 at Vp=V0 and I2=I0 is made to flow when Vp<V0. Consequently, composite current value I1+I2 for generating saw tooth wave increases and decreases according to the amount of drop-out. Accordingly, inclination of the saw tooth wave also changes, and consequently, pulse width of a PWM signal outputted from a comparator 23 also changes.

IPC: G06T3/60
Filed: 1986-11-21
Abstract: PURPOSE:To easily realize enlargement, reduction and rotation by adopting run coding data and operating in terms of real numbers the run coding data. CONSTITUTION:Data in which a picture is converted into a run code is inputted in a step 10. In a step 11, the run code data is coordinate-converted in a lateral direction. In a step 12, run code data which has coordinate-converted is converted into the run code in the lateral direction. This is to sequentially read the run code in the lateral direction along a scan direction so as to generate the run code in the lateral direction. It is not necessary to restore data to a picture element, and all are realized in the area of the run code. In a step 13, run code data in a longitudinal direction is coordinate-converted in longitudinal direction. This is realized by multiplying and adding a prescribed real number to the starting point coordinate and the end point coordinate of the run code in the longitudinal direction.

Title: High-frequency high-output-power transistor
Inventor: WAKAMATSU SHIGEMI
IPC: H01L23/66
Filed: 1989-10-23
Abstract: PURPOSE:To realize excellent matching characteristics by providing a solder dam on a metallized surface between each transistor chip and each capacitor chip. CONSTITUTION:On a metallized surface 7 which is partitioned with a solder dam 8, capacitor chips 11a-11c and transistor chips 10a and 10b are alternately brazed. An input matching capacitor 6 is brazed to the side of an input terminal 1 of a grounding metallized surface 5. The linear solder dam 8 which is used for connecting metal thin wires 15a-15d in a conventional device is elongated in branched shapes between the capacitor chips 11a-11c and the transistor chips 10a and 10b. Even if the chips are scrubbed, brazing filler metal does not flow into the neighboring chip regions. Thus, the perfect symmetry can be maintained at an equal interval, and the excellent matching characteristic can be realized.

Title: Burst information transmission system
Inventor: SHIBUYA TOSHIYUKI
IPC: H04L12/28
Filed: 1994-11-11
Abstract: PURPOSE: To reduce delay of data between the communication terminals by multiplexing the effective range information on the data contained in the payload and controlling the data contained in the payload based on the effective range information. CONSTITUTION: A transmission marker recognizing part 2 takes the marker of the cell to be transmitted next out of a marker queuing buffer 1 based on the control of a timing controller 8 and then sets the byte number of the designated data to a payload data buffer 5. When the buffer 5 stores the data in response to the set byte number, a multiplexing part 6 multiplexes the payload data and the corresponding marker. Then a multiplexing part 9 multiplexes the output of the part 6 and an ATM header and sets them to a transmission cell buffer 10. When the transmission of cells is completed at the buffer 10, the controller 8 takes again the marker of the cell to be transmitted next out of the buffer 1 and sets it to the part 2. Thus the variable control is possible to the quantity of data to be contained in the payload and the data delay time is reduced.

Title: Withstand voltage testing device
Inventor: IKETANI IKUYA
IPC: G01R31/12
Filed: 1994-11-11
Abstract: PURPOSE: To detect a corona voltage with a sufficiently large amplitude. CONSTITUTION: In a withstand voltage testing device which detects a corona voltage generated from an object 4 to be tested by applying a voltage to the object 4 from a testing power source 1, an inductor 3 is connected in series between the power source 1 and object 4. In addition, a capacitor is connected in series with the inductor 3 so as to change the resonance frequency of a serial resonance circuit composed of the inductor 3 and capacitor to a testing frequency. Since the inductor 3 enlarges the sporadically generated corona voltage, the voltage can be detected with high sensitivity and, since the resonance frequency of the serial resonance circuit composed of the inductor 3 and capacitor is changed to the testing frequency, the impedance of the testing frequency can be reduced to about zero.
