Title: Protection circuit for semiconductor switch device
Inventor: HAGIWARA YOSUKE
IPC: H01L27/088
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To prevent thermal destruction of a semiconductor switch element that is a component of a semiconductor switch device. SOLUTION: A protection circuit 1 consists of a current sensor resistor 2 that is connected between the source of a power MOSFET 14 and one output terminal 15b and an npn gate control transistor(TR) 3 that becomes conductive when the voltage drop across the current sensor resistor 2 exceeds a given voltage. Since the current sensing resistor 2 has a positive temperature coefficient, the resistance of the current sensor resistor 2 increases as the temperature rises and the voltage applied between the base and an emitter of the gate control TR 3 also increases. Consequently, the gate voltage of the power MOSFET 14 decreases to suppress the drain current. Since the power consumption of the power MOSFET 14 is reduced, the drain breakdown voltage can be made higher so as to prevent thermal destruction of the power MOSFET 14.

Title: Stator
Inventor: YAMANE MITSURU
IPC: H02K1/14
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To maintain insulation resistance in high-humidity environments as well and enhance working efficiency by adopting a resin molding composed of aromatic nylon of polyamide resin, glass fibers, flame retardant, and a flame- retardant auxiliary agent for the end insulator. SOLUTION: The material of the end insulator of the stator uses aromatic nylon as polyamide resin and contains glass reinforcing material, flame retardant, and a flame-retardant auxiliary agent. The aromatic nylon is composed of a polymer of hexamethylenediamine and terephthalic acid and a polymer of an amine isomer and terephthalic acid. Heat resistance is enhanced and thermal deformation and melting become less prone to be caused in a solder joining process owing to the action of terephthalic acid, and further the density of crystalline structure is enhanced in terms of molecular structure. Thus, the material is ideal for dip soldering. In addition, since in aromatic nylon, amide groups which cause intermolecular bonding of water molecules are less in number, the water-absorbing rate is reduced and high insulation resistance can be maintained.  As a result, insulation resistance can be maintained in high- humidity environments and working efficiency can be enhanced.

Title: Optical external modulator
Inventor: HIGAMI TOSHIYA
IPC: G02F1/11
Filed: 1993-04-21
Abstract: PURPOSE:To reduce attenuation in light and to reduce dispersion in a characteristic. CONSTITUTION:In an optical external modulator where a lower electrode 2, a piezoelectric body 3 and an upper electrode 4 are laminated successively on one side surface of a supporting substrate 1 having an optional acoustic impedance, and an optical waveguide 5 is arranged on the upper electrode 4 or on the other surface of the supporting substrate 1, and the polarization plane of light propagating through the optical waveguide 5 is modulated when the piezolectric body 3 is driven by impressing a high frequency signal between the lower electrode 2 and the upper electrode 4, the same optical waveguide 2 with the nearly same aoustic impedance as the acoustic impedance of the supporting substrate 1 is provided. The efficient optical external modulator is obtained since no reflection attenuation due to the difference of the acoustic impedance occurs in a process where a sound wave emitted from the piezoelectric body 3 is propagated through the supporting substrate 1 to be made incident on the optical waveguide 5.
