Title: Optical information recording medium
Inventor: NITO KEIICHI
IPC: G11B7/253
Filed: 1986-09-20
Abstract: PURPOSE:To make the reduction of a noise level, etc., possible by decreasing the anomaly of double refraction, by using a resin material based no a polycarbonate resin low in a content of low-MW components as the base material of a transparent base of an optical information recording medium. CONSTITUTION:A polycarbonate resin is produced by, for example, a process comprising reacting a dihydric phenol compound (e.g., bisphenol A) with phosgene in the presence of an acid binding agent and a solvent. The obtained polycarbonate resin is purified to produce a polycarbonate resin having an MW (in terms of polystyrene) <=500 and a content of low-MW components <=4wt%. A transparent base is made from the purified polycarbonate resin and an optical information layer is formed on the transparent base to form an optical information recording medium. In this way, the anomaly of double refraction resulting from foreign matter formed by the segregation or condensation of low-MW components in the resin can be reduced.

Title: Transmitter
Inventor: MAEKAWA TAKAAKI
IPC: H04B13/02
Filed: 1986-09-20
Abstract: PURPOSE:To increase mechanical strength, to attain stable insulating property, and to stabilize the radiation of an electromagnetic wave, by adhering a circular insulating material at the outer periphery of a metallic cylinder, arranging a circular conductor at the outer periphery of the cylinder, and setting the conductor and the metallic cylinder as a radiating part, in a radiator which radiates the electromagnetic wave from underground. CONSTITUTION:The circular insulating material 12 is adhered at the outer periphery of the metallic cylinder 10, and a cylindrical conductor 13 is arranged at the outer periphery of the cylinder, and constitution to radiate the electromagnetic wave from the conductor 13 and the metallic cylinder 10, is formed. As the insulat ing material 12, a thermoplastic resin, or a thermosetting resin is impregnated in a glass cloth, and it is formed and used in a tape, or a sheet shape. By the above constitution, rotational torque supplied to one side of the metallic cylinder 10 is transferred directly to the other side of the cylinder 10, because the metallic cylinder 10 itself is a rigid body, and the mechanical strength of the the cylinder 10 cannot be impaired, Also, since the above stated torque is not applied on the insulating material 12 which supports the conductor 13, there will be no fear to impair insulating strength due to the damage of the insulating material 12.

Title: Short-circuit protection circuit and power darlington transistor module
Inventor: TAKADA IKUNORI
IPC: H01L29/73
Filed: 1993-09-08
Abstract: PURPOSE:To effectively prevent 'destruction due to short-circuit of load' of a power Darlington transistor(TR). CONSTITUTION:When a voltage between a base BX and an emitter E of a final stage TR of the power Darlington TR 20 is higher than a prescribed voltage depending on a base-emitter forward voltage of a protection bipolar TR 32, the protection bipolar TR 32 is turned on and a base current IB of a TR of a 1st stage of the power Darlington TR 20 is bypassed to the emitter E of the TR at the final stage. Thus, an excessive increase in a collector current IC of the power Darlington TR 20 is suppressed and 'destruction due to short- circuit of load' is prevented. Thus, since the voltage is independent of the number of stages of the power Darlington TR and temperature, the short-circuit protection circuit is easily designed to warrant prescribed bypass over the entire operating temperature range with respect to various stage number of the power Darlington TR.

Abstract: PURPOSE:To improve the durability by constituting the apparatus so that the force caused by heat expansion difference is not applied onto a heat insulating member. CONSTITUTION:In a suction casting apparatus having a structure closing a sprue part 56a in a mold 50 by abutting the tip surface 72s of a gate piston 72 on the surface of a lower die 54 in a die and covering a recessed part formed at the tip surface 72s on the upper end of a molten metal passage 58 formed in the lower die 54, the wall surface of the recessed part formed at the gate piston 72 is covered with the cup-like heat insulating member 80. In the condition of closing the sprue part 56a with the gate piston 72, the heat insulating member 80 is fitted to this gate piston 72 so as not to abut on the lower die 54. Therefore, the shock at the time of abutting the tip surface 72s of the gate piston 72 on the surface of the lower die 54 is not applied directly onto the heat insulating member 80, so the durability of the heat insulating member 80 is improved.

Abstract: PURPOSE: To determine with high accuracy, a phase difference between a voltage and a current component of a selected tone by generating a product of a voltage and current generated by a plant component and then generating a sine and a cosine signals by adding, multiplying and dividing the integrated values of the product. CONSTITUTION: A signal selected by a selector 22 is supplied to a band-pass filter 132, synchronized with a basic frequency 'f' of a power network N1 . When this method is applied to a filter connected to a DC network, a signal UN1 which shows a value of voltage or current detected by the network N1 is selected. When applied to a plant component connected to an AC network, a signal U is selected. Either the signal U or the UN1 is given to a means for carrying out this method. A signal is properly selected by the selector 22, so that the selection of the supplied voltage can be symbolized, thereby determining a phase difference can be determined with high accuracy.

After that, As-doped polycrystalline silicon 13 is deposited in an LPCVD furnace using AsH3 and Si3N4; the polycrystalline silicon is made a low resistance and, at the same time, an As diffusion layer 14 is formed. Then, a W film 15 is formed in an LPCVD furnace using H2 and WF6; CF4, O2 and N2 are introduced; an uneven part on the surface of W is made smooth by a dry etching operation. Then, a pure Al electrode 17 is formed via a Ta2O3 film 16. Thereby, it is possible to suppress the nonuniformity of a film thickness of a dielectric film and to suppress an increase in a leakage current.
