Abstract: A semiconductor device sealed with mold resin (9) is disclosed. The device includes a semiconductor substrate (1) having a main surface and an element (2) formed on the main surface of the semiconductor substrate (1). A stress buffering film (6) for protecting at least the element (2) from stress of the mold resin (9) is provided on the semiconductor substrate (1) so as to cover at least the element (2). The entire semiconductor device is covered and sealed with mold resin (9). The stress buffering film (6) is formed of organo-silicone ladder polymer having a hydroxyl group at its end. In the semiconductor device, water does not get into an interface of the stress buffering film (6) and the underlying substrate (1), resulting in an enhancement of the moisture resistance of the semiconductor device.

Abstract: An interface circuit (10) for coupling a parallel data device (12) to a serial data channel (14, 16) over which Manchester-type codes are transmitted. In the interface circuit, an efficient and reliable Manchester decoder (22), comprising a flip-flop (50), an exclusive-or gate (52), and at least one delay line (58A or 58B) separates the data and clocking signals. The serial data signals are clocked into a serial register (30) under control of the external clocking signals from the channel. A carrier detector (24) enables the serial register only when valid information signals are present. A parallel data register (40) receives in parallel the data from the serial data register. To get in phase the external clocking signals with the internal clock source, an internal clock synchronizing circuit (34, 42) recycles the internal clock source upon the occurrence of a synchronizing character that is transmitted over the serial data channel. In this fashion, the internal operations of the parallel data transfers are in phase, but isolated from the external clocking signals so that in the event that the external clocking signals become corrupted due to noise or simultaneous transmissions of information signals by different devices, the internal parallel transfer operations may continue freely without disruption.

Abstract: Disclosed is a method of making In-based DFB lasers that can reliably prevent erosion of the grating (12) in the InP substrate (11) surface during heating of the substrate to the deposition temperature for the overlying epitaxial quaternary material (e.g., 130), and that can make possible deposition of essentially defect-free overlying quaternary material. The method comprises heating of the substrate in an appropriate As and P-containing atmosphere and, optionally, deposition of a minor amount of As, Ga and P-containing protective material (121) at an intermediate temperature, e.g., at 500°C. Exemplarily the atmosphere consists essentially of H₂, AsH₃ and PH₃, at 500°C a very small amount (corresponding to only a few monolayers) of GaAsP is deposited, followed by deposition of a somewhat larger amount (corresponding to about 7 nm) of InGaAsP (λ g ∼1 µm). Upon completion of the deposition of the protective material the substrate is heated in H₂-AsH₃-PH₃ to 625°C and epitaxial overlayer material deposited in conventional fashion.

Abstract: A thermal inkjet printhead is disclosed having improved reliability and thermal efficiency. The printhead includes heater resistors (14) and thin protective regions (46) positioned above the heating resistors for protecting the heating resistors from corrosion and cavitation damage from the ink. The heating resistors are positioned substantially within the geometric confines of the portion of the protective regions exposed to the ink. Positioned between the resistors and the underlying printhead structure are field oxide regions (60) that thermally insulate the heating resistors from the underlying printhead structure. Positioned between the resistors and the underlying printhead structure is a passivation layer consisting of a middle layer (62) of phosphorus glass, an underglaze (64) between the middle layer and the underlying printhead structure, and glass mesas (66) between the middle layer and the resistors. The underglaze helps prevent phosphorus from the middle layer from contaminating the underlying printhead structure. Similarly, the glass mesas prevent phosphorus from the middle layer from contaminating the resistors.

Abstract: A magnetooptical recording medium has at least a first magnetic layer and a second magnetic layer which are mutually exchange-coupled. The first magnetic layer has a compensation temperature within a range higher than a room temperature but lower than the Curie temperature of the second magnetic layer. Under the application of an external magnetic field of a suitable intensity to the recording medium, the magnetization of the first magnetic layer is oriented in a stable direction with respect to the external magnetic field at the room temperature. At the vicinity of the compensation temperature of the first magnetic layer, the magnetization of the first magnetic layer is oriented in a stable direction with respect to the exchanging-coupling with the second magnetic layer. The second magnetic layer maintains a predetermined magnetization state at any temperature from the room temperature to the compensation temperature of the first magnetic layer regardless of the presence or absence of the external magnetic field. Simultaneous recording and reproducing can be performed using the above medium.

Abstract: In a manufacturing method of thin film transistor, when impurity ions are introduced in a channel region between source and drain regions in a semiconductor layer, an insulator layer is formed on the semiconductor layer first. Then, impurity ions generated on high frequency discharge are introduced through the insulator layer into the semiconductor layer under a specified acceleration voltage. Then, the introduction depth of impurities and the amount of the impurities to be introduced in the channel region can be controlled or the threshold voltage of the thin film transistor can be controlled. This method can be applied to a large substrate.

Abstract: Disclosed is an ink-jet type recording device comprising a drive signal generation circuit (84) for generating trapezoidal drive signal in synchronization with a timing signal applied from an external device, switching transistors (85) respectively for outputting a drive signal to piezoelectric vibrators (48) in accordance with a printing signal applied form an external device, and control signal generation means (80) for generating a pulse signal to turn on the switching transistors (85) so that part of the drive signal being output to the piezoelectric vibrators (48) respectively set in non-printing condition in synchronization with a timing signal. Part of the drive signal is applied to the piezoelectric vibrators (48) belonging to the nozzle openings that do not jet out ink droplets in accordance with the pulse signal, so that menisci in the nozzle openings can be vibrated slightly, respectively. As a result of this, ink existing in a pressure generation chamber and ink existing in the neighborhood of the nozzle opening are mixed together and thus solvent is supplemented to the ink existing in the neighborhood of the nozzle opening, thereby preventing formation of an ink film due to evaporation of the solvent. Also, even in the non-printing period the piezoelectric vibrators respectively generate heat to thereby prevent absorption of humidity from the peripheral environment.

Abstract: An insulated conductor (20) for use in a communication cable which includes a filling material (30) includes a copper conductor (25) and a composite insulation system (27) comprising two concentric layers of insulation. An inner foam layer (28) of the insulation comprises a cellular plastic material (28) which includes a stabilizer system . An outer layer (29) of the insulation is referred to as a skin and comprises a stabilized solid plastic material. The stabilizer system in each of the cellular and solid layers includes a bifunctional portion that functions as an antioxidant and as a metal deactivator and that has a relatively high resistance to extraction. The level of the bifunctional portion of the stabilizer in the cellular material is substantially greater than that in the skin inasmuch as it has been found that the level of the stabilizer cellular layer contiguous to the copper wire determines the oxidation performance level of the composite insulation.
