Title: Resin sealed integrated circuit device
Inventor: MIKINO HIROSHI
IPC: H01L23/495
Filed: 1985-04-19
Abstract: PURPOSE:To prevent a package from warping, by defining the position of a lead such that the elastic neutral axis of the package coincides with the central axis while defining the position where the lead is led out such that it is deviated from the central axis. CONSTITUTION:The surface of the principal portion of a lead 1 sealed in a package is placed close to the central axis phi-phi of a resin body 3 such that the neutral axis N-N coincides with the axis phi-phi, whle the lead 1 is bent at the portions 6 near the side faces within the resin body 3 such that the lead is led out at positions lower than the central axis. Accordingly, the warpage of the package can be decreased without altering a conventional standard in any way in the overall shape, whereby pellet cracks or variations in electrical characteristics caused by the warpage are decreased. Thus the reliability of IC products can be improved.

Abstract: PURPOSE:To reduce the polarization dependence of an optical amplification and relay system by providing a polarization modulation means wherein an optical signal which is output from a light source is modulated so as to maintain a linear polarization and the polarization state of the modulated optical signal is changed periodically up to an orthogonal state. CONSTITUTION:An optical signal which is output from a transmission light source 9 by a linear polarization inside a polarization dependence-reduced optical transmission device A at a transmission terminal station is coupled to an external modulator 10 which converts it into an optical data signal by a polarization-preserving optical fiber 12 so as to maintain a polarization state. In addition, it is coupled, by the polarization-preserving optical fiber 12, to a polarization modulator 11 as a polarization modulation means which changes the polarization state of the optical signal up to an orthogonal state at a cycle of 1msec. Them, an optical signal output S1 from the optical transmission device A is amplified, relayed and transmitted by an optical fiber 7 for transmission and by an optical fiber amplifier 8, and an optical signal S2 is input to an optical reception device B. Thereby, even when the polarization state of the optical signal of the light source 9 is changed, the S/N of the optical signal can be made definite.

The 2nd memory basic calculation procedure storing section 41 stores a basic calculation procedure prepared by disintegrating a fuel arrangement preparing procedure into unit modules. Then the 3rd memory fuel arrangement calculation procedure storing section 42 stores plural fuel arrangement plan preparing procedures prepared by combining the modules. Upon receiving the data of a fuel aggregate expected to be charged, an arithmetic section 40 reads a fuel arrangement plan preparing procedure from the storing section 42 and causes the ideal form of fuel arrangement read from the storing section 43 to be generated in accordance with the procedure. When the ideal form is not materialized, a fuel arrangement plan close to the ideal form is caused to be generated in accordance with the alternate measures. Thus fuel arrangement plan is automatically generated.

IPC: H01L43/08
Filed: 1993-04-09
Abstract: PURPOSE:To provide a method for improving the saturation field in a multilayer magnetoresistive effect film employing a magnetic layer having face-centered cubic structure by employing a material having a face-centered lattice structure at a part of the magnetic layer with the (111) face of a crystal being oriented in parallel with the substrate. CONSTITUTION:In order to increase the magnetoresistive variation rate of a multilayer magnetoresistive effect film, (111) face of the crystal in a magnetic layer 11 having a face-centered structure is oriented in parallel with a substrate 14. Consequently, the exchange interaction between the magnetic layers 11 is weakened thus lowering the saturation field. The direction of magnetization is controlled by varying the direction of magnetic anisotropy for each magnetic layer 11, by employing two different types of magnetic layers 11, or by applying an exchange bias field from an antiferromagnetic layer to the magnetic layer 11. Consequently, a low saturation field is obtained.

Title: Generator for phase synchronizing signal
Inventor: TERADA MINORU
IPC: H01Q3/42
Filed: 1978-07-07
Abstract: PURPOSE:To obtain an electronic scan antenna of simple constitution with a phase error suppressed low without providing a transmission system with a phase shifter, by allowing a phase synchronous loop to attain high-gain phase synchronization. CONSTITUTION:Phase detectors 15l to 15n detect phase differences between a reference signal supplied from reference signal generator 1 and signals obtained by extracting parts of oscillation output of voltage tuning signal oscillators 17l to 17n from directional couplers 21l to 21n. Then, the detected error signal voltages are applified by video amplifiers 16l to 16n and then applied to oscillators 17l to 17n so that phase difference between signals of frequencies of oscillator's own and the reference signal will disappear. During this control mentioned above, phase differences among element antennas required for the excitation of the scan are controlled by converting a digital signal sent from phase-shift control signal generator 5 into a fixed analog value signal by D/A converters 18l to 18n and by superposing the obtained signal upon the difference voltage, so that the phase error can be suppressed without providing the transmission system with a phase shifter.

Then the mixture added with the binder like the organic tin is formed in the form of a lump between electrode 3 and heat generator 4 and then burnt. The surface of gas-sensitive substance 2 thus formed is made porous due to the gas or the like produced by the decomposition of the binder through burning, and the water solution of the aluminium hydroxy chloride is impregnated into this surface. Thus substance 2 impregnated by the alumina sol can be burnt at about 500°C after drying.
