Patent JP-H02246218-A (JP)
Title: Manufacture of semiconductor device
Inventor: KIKUCHI YOSHIBUMI
IPC: H01L21/321
Filed: 1989-03-20
Abstract: PURPOSE:To secure junction strength between a bump and a substrate while making the diameter of the bump compact and form the bump of photoresist that is thinner than plating on the bump by forming an opening at an opening part which is formed in resist films on the substrate in such a manner that the diameter of the opening is smaller than that of its base and forming an electrode, thereby performing plating so that the thickness of plating is thicker than the film thickness of resist. CONSTITUTION:An opening 11 is forming at an opening part in resist films 8 and 9 which are formed on a substrate 3 in such a manner that the diameter of the opening is smaller than that of its base and an electrode is formed by performing plating at the opening 11 so that the thickness of plating is thickener than the film thickness of resist. After that, when both photoresist films 8 and 9 are removed, the predetermined bump 12 is formed on a pad and the head part 12a of the bump 12 swells crosswise from the opening part of the opening 11. However, as the diameter of the head part is smaller than that of its base, the diameter of the head part becomes almost equal to that of the pad 4. Consequently, the diameter of the bump head part 12a can be reduced without reducing a junction area with the pad 4. Junction strength between the bump 12 and the substrate 3 is thus secured while making the diameter of the bump 12 compact; besides, the bump 12 is formed of resist that is thinner than the plating thickness of the bump 12.

Title: Power amplifying circuit
Inventor: ISHII SATORU
IPC: H03F3/30
Filed: 1981-05-06
Abstract: PURPOSE: To prevent the occurrence of oscillation without deteriorating high frequency characteristics by decreasing the operating voltage range of a class "B" amplifying circuit for powering up a class "A" amplifying circuit.  
     CONSTITUTION: A class "B" amplifying circuit 2 for a power source exercises control to reduce a supply voltage extremely while the transistors (TR) Q 1  and Q 2  of a class "A" amplifying circuit 1 are operated invariably in an active region. In this case, the base-emitter voltages VCE of TRs Q 5  and Q 6  are considered. When the base input of the Q 5  is negative, the Q 5  is off and the VCE is equal to a power voltage B 1 . When the base input of the Q 5  is positive, the Q 5  is on, but the values of resistances R 7  and R 8  are small, so the VCE is a little bit lower than the B 1 . Since variation in the VCE of the driver TRs Q 5  and Q 6  is less, variation in the collector-base parasitic capacity of the both is also less. Consequently, the stability of the closed loop characteristics of a negative feedback circuit is improved.

Filed: 1990-03-20
Abstract: PURPOSE: To improve the safeness of an engine by providing it with a means for generating parameter signals representative of an engine condition and generating non-recoverable stall output signals in accordance with temperature signals representative of an engine temperature downstream of the engine combustor and by detecting an engine stall accurately. CONSTITUTION: A control system 50, which is connected up to a gas turbine engine 10 to receive output signals from a temperature sensor 52, a fan speed sensor 54, a compressor discharge pressure sensor 56 and an engine intake temperature sensor 58, includes an idle detector means 60. When receiving an input indicator of a power-level angle(PLA) or other given inputs from a thrust display and finding the PLA equal to or larger than the idle, the idle detector means 60 produces an output to energize a stall detector means 64. In this condition, when detecting stall generation from the signals from the compressor discharge pressure sensor 56, the stall detector means 64 energizes, via a delay means 70, a comparator means 74, which in turn determines whether the stall is recoverable or not and then causes an indicator 80 to operate to this effect.

Title: Ceramic composite material containing carbon-coated sic whisker
Inventor: RINDA SHII SOIYAA
IPC: C04B35/80
Filed: 1989-03-20
Abstract: PURPOSE: To obtain a silicon carbide whisker reinforced ceramic composite material having improved toughness by molding a mixture composed of a particulate ceramic material and carbon coated silicon carbide whiskers and sintering the ceramic material by heating.  
     CONSTITUTION: The uniform mixture composed of the particulate ceramic material and the silicon carbide whiskers subjected to carbon coating is formed. The mixture is then molded and the ceramic material is sintered by heating the mixture during or after the molding, by which the objective composite material is obtd. The carbon coating limits the formation of oxide layers on the whisker surfaces by prohibiting the diffusion of oxygen to the whisker surfaces. The carbon coating forms silicon carbide layers by reacting with the silicon oxide existing on the whisker surfaces at a high temp. The carbon coated whiskers do not exhibit excessive adhesive power to a ceramic matrix and are withdrawn from the ceramic matrix when the matrix is subjected to crack forming stresses. The carbon coated whiskers, therefore, well absorb the cracking energy and improve the fracture toughness of the ceramic composite material.
