Title: Semiconductor device and plating device
Inventor: MAEJIMA YOSHIHISA
IPC: H05K3/34
Filed: 1990-11-14
Abstract: PURPOSE:To ensure the mechanical strength and electric reliability as well as improve operability during board mounting by plating a thick film solder layer on a lead that electrically connects a semiconductor device mounted on a film. CONSTITUTION:A top press die 16 is pressed from above on a semiconductor device 8 and the base of an outer lead 4b and a tape film 1 below this are held together by the top press die 16 and a lower stand 17. At the same time, a cathode 13 is pressed from above on a probe pad 4c and a pressure conductive rubber 14, the base of an outer lead 4b, and the tape film 1 below are held together by the cathode 13 and the supporting stand 12. Next, while applying a certain amount of voltage between the cathode 13 and an anode 15, a plating liquid 18 is funneled upwards from below in the direction indicated by the arrows. In this way, the plating liquid 18 flows upwards along the tapered portions of the supporting stand 17 and reaches the bottom surface of the outer lead 4b. As a result of this process, a thick film solder layer 19 is formed on the outer lead 4b of the semiconductor device.

IPC: G11B7/095
Filed: 1992-10-21
Abstract: PURPOSE:To exactly detect the two dimensional tilt of an optical disk and to exactly correct the tilt of the optical disk in a short time. CONSTITUTION:A two dimensional tilt sensor 1 comprizes LED 2a, LED 2b emitting light toward an optical disk 4 and photdiodes 3a, 3b, 3c, 3d receiving a reflected light from the optical disk 4 and arranged two dimensionally adjacent to each other. A tilt angle theta1 in the radial direction from the difference between the photodiodes 3a and 3c arranged in the radial direction and a tilt angle theta2 in the tangential direction from the difference between the photodiodes 3b and 3d arranged in the tangential direction are simultaneously calculated. A compensating circuit drives a two axis actuator 5 so that the tilt angle theta1 and the tilt angle theta2 become zero and corrects the tilt of the optical pickup to the optical disk 4. Preferably, by adjusting and normalizing the level of the output signals of the photodiodes 3a, 3b, 3c, 3d, the tilt of the optical disk 4 is corrected by the normalized signals.

Title: Combustion control device
Inventor: KAWAMURA KIMINARI
IPC: F23N5/02
Filed: 1993-12-09
Abstract: PURPOSE:To cope with external factors, such as variation in the oxygen content of the air for every unit cubic volume due to variation in ambient temperature and maintain an enhanced combustion efficiency and hence save energy. CONSTITUTION:A temperature sensor is installed to detect an outlet side- temperature of cold and hot water from an evaporator in a refrigeration cycle 7. An oxygen concentration sensor is installed on the downstream side of a heat exchanger 2. A optimum combustion quantity is computed based on a detected value of the oxygen sensor. The opening of a fuel valve 3 is adjusted based on the computed value. The supply of combustion air which is determined by the computed value is corrected based on the detected value with the oxygen concentration sensor, thereby adjusting the opening of an air valve 4 based on a post correction value. When the detection oxygen concentration equivalent to the supply of combustion air is small, the currently available air quantity will be insufficient to comply with perfect combustion to a satisfactory extent. If the concentration is large, the combustion air quantity is too surplus to reduce the combustion air quantity within a range which does not interfere with the combustion and inhibit heat loss of waste gas.

Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To reduce the distortion of an amplifier and to miniaturize the amplifier by constituting a characteristic improvement circuit for improving the linearity of the input/output characteristic of a nonlinear amplifying element only through a passive element. SOLUTION: The nonlinear element 1 grounds the source electrode S and connects a matching circuit 2 to a gate electrode G and a matching circuit 4 to a drain electrode D. When the resistance value of a resistor 6 is in the range of 0.1-10Ω in a series circuit 10, a reflection characteristic and a reflection angle become almost constant. When the capacitance value of a capacitor 5 is changed, although a pass phase can be changed a load characteristic with the matching circuit 2 is changed by the value of the capacitor 5. Thus, the matching circuit 2 is changed and matching is executed. Thus, the series circuit 10 constituted of the capacitor 5, the resistor 6 and an inductor 7 is provided for the circuit of an input side and respective values and selected arbitrarily.  Consequently, the phase characteristic can be changed (improved), while a matching characteristic is maintained. Thus, the distortion characteristic of the amplifier can be changed.
