Title: Composite diode
Inventor: ETO HIROKI
IPC: H01L25/04
Filed: 1990-10-19
Abstract: PURPOSE:To associate an SBD having a small forward rising voltage VF by placing a P-N diode chip in which a base is led as an anode, on the extended part of the end of an anode lead, and placing an SBD chip on an island. CONSTITUTION:An SBD chip 22 is secured in an eutectic crystal on an island 21, and an electrode pad on the surface is wire bonded to one anode lead 23 via a gold wire 29. That is, a substrate of the chip 22 becomes a cathode leading electrode. One P-N diode chip 28 is secured to an extended part 26 of the other anode lead 24 in an eutectic crystal, and the surface electrode pad and the island are wire bonded therebetween via a gold wire 29. Accordingly, since the substrate of the chip 29 is used as an anode leading, its conductivity is reverse to that of prior art. Thus, since only the chip 22 is placed on an island 21, the chip 22 having larger Schottky junction area can be placed.

Title: Frequency converter
Inventor: YUMIKURA TADAAKI
IPC: H04B1/26
Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To improve the noise index of a mixer output by using a frequency signal of a difference at frequency conversion by the mixer as an intermediate frequency and receiving this frequency signal of the difference by a next-stage connecting circuit, having high input impedance which is several times as large as the mixer output impedance. SOLUTION: The frequency signal of a difference generated by mixing the frequency signals of a high-frequency device RFIC and a sweep local oscillator 25 is processed by a mixer 20 to a low frequency which makes small effects on a mismatch of line impedance, e.g. an intermediate frequency of tens of MHz. Connections with the mixer 20 and a low-noise amplifier 30 which has a line length shorter than low intermediate-frequency wavelength and input impedance several times as large as the output impedance of the mixer 20 are made. Consequently, loss of about 4 dB accompanying matching with a next stage among conversion loss items of a diode mixer itself as the mixer 20 can be almost eliminated, so that the noise index characteristic of the frequency conversion device can be improved by nearly 4 dB.

Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To provide heat resistance and impact resistance while maintaing superior steam barrier properties and easy opening and sealing properties by laminating a polyamide resin layer and a cyclic olefin resin layer via an adhesive layer. SOLUTION: A laminated film comprises a polyamid resin layer A and a cyclic olefin system resin layer C that are laminated to each other via an adhesive layer B. As a laminated film like this, a laminated film or the like is taken for example in which both the A and C layers are a single layer, or the A layer is a double layer, while the C layer is a single layer, and the A layer constitutes an outermost layer. In a laminated film like this, the total thickness of the A layer ranges 5 to 50μm, the total thickness of the B layer 5 to 20×m and the thickness of the C layer 5 to 150μm. When the thickness of the A layer becomes less than 5μm, the heat and impact resistances are reduced, while when it exceeds 50μm, the easy opening property is reduced.  When the thickness of the B layer becomes less than 5μm, the adhesive force is reduced, while it exceeds 20μm, the easy hand-tearing property is reduced. When the thickness of the C layer becomes less than 5μm, the easy opening property and moistureproofing property are reduced, while when it exceeds 150μm, the flexibility of the laminated film becomes poor.

Title: Intake silencer for internal combustion engine
Inventor: TESHI MASATERU
IPC: F02F7/00
Filed: 1992-09-28
Abstract: PURPOSE:To improve the shape of a resonator provided at the intake passage of an automobile engine so as to increase rigidity with simple structure. CONSTITUTION:A resonator provided at the intake passage of an automobile engine is formed of a container of such shape that the upper face of an upper plate 3 is formed into convex shape and the lower face of a bottom plate 2 is formed into concave shape. This resonator 1 is disposed at the upper part of the cylinder head cover of the engine.

Title: Sealing device for rod of hydraulic cylinder
Inventor: NAKAJIMA YOKICHI
IPC: F16J15/3236
Filed: 1985-12-16
Abstract: PURPOSE:To prevent the abnormal rise of the hydraulic pressure in an intermediate chamber by forming the groove part into which the O-ring of a buffer device is accommodated so that the O-ring does not shift in the direction of the groove width. CONSTITUTION:The bottom width of a groove 60 into which an O-ring 51 and a buffer ring 50 are accommodated is represented by the interval between the straight lines 61 and 65, and is made a little narrower than the width dimension of the sectional surface of the deformed O-ring 51. When the hydraulic pressure in a hydraulic chamber 8 increases during the operation of a hydraulic cylinder, also the hydraulic pressure in the left side chamber 70 for the O-ring increases, and the O-ring 51 is pressed rightward by the hydraulic pressure. Therefore, though the oil in the right side chamber for the O-ring is pushed into an intermediate chamber 55, the intermediate chamber 55 can be kept in a low pressure, since the quantity of the pushed-out oil is enough small to be absorbed by the deflection of a U-packing 5c.

IPC: G09F9/33
Filed: 1988-11-10
Abstract: PURPOSE:To prevent the increase in the weight of a display screen and its deformation by forming a space with partitions. CONSTITUTION:A resin segment 1 is composed of seven 8-shaped open hole parts 2, a frame body 3 surrounding the circumference, and the partitions 4 forming the space between each segment 1 and the frame body 3. A slope 6 continuously rising from the end of each 8-shaped open hole part 2 is provided, and a bar-like opening hole part 7 is formed on the top thereof to constitute a hollow segment part. The partition 4 is formed outside the bottom 5, and a light emitting plane is not filled with thermosetting resin but elsewhere is filled with the resin. Since the resin has a space not filled with resin, the weight of a large-sized semiconductor display device does not increase when it is produced. In addition, the bending of the display screen that may be expected due to the scaling up of the device can be prevented by the formation of the space not filled with the resin.
