Title: Semiconductor integrated circuit
Inventor: TAKIGAWA KUMIKO
IPC: H04B1/3822
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To improve the gain and noise characteristics of a semiconductor integrated circuit by providing a low-noise amplifier at the position where the distances from outside-package pins to pads become the shortest. SOLUTION: A low-frequency-band low-noise amplifier 121 and a high- frequency-band low-noise amplifier 123 are respectively supplied with stable bias currents from their bias circuits 125 and 126. The bias currents are supplied to the amplifiers 121 and 123 after the currents are converted into bias voltages by means of a bias resistor 122 for low-frequency-band low-noise amplifier and a bias resistor 124 for high-frequency-band low-noise amplifier. The circuits of the amplifiers 121 and 123 are arranged between the output pin 103 of the amplifier 121 and the input pin 109 of the amplifier 123 so as to make the distances from the front ends of the outside-package pins of the amplifiers 121 and 123 to pads the shortest. In addition, the grounding pins of the amplifiers 121 and 123 are prevented from being arranged adjacently to each other.  Therefore, the adverse effect of transformer coupled connector between the pins can be reduced and, accordingly, the gain and noise characteristics of a semiconductor integrated circuit can be improved.

Title: Projection type cathode-ray tube
Inventor: MAKABE KAZUO
IPC: H01J29/00
Filed: 1983-06-17
Abstract: PURPOSE:To effectively prevent the destruction of a sealing section resulting from thermal expansion and the leak of coolant and the generation of a bubble following the coolant leak by providing a notched section that performs external air ventilation on a bracket arranged on the external surface of a face section and arranging a bellows assembly body that is airtightly connected to the coolant space in this notched section. CONSTITUTION:Coolant 9 is injected from an injection port 10 and the space between both panels and the inner part of a bellows assembly body 16 are filled and sealed. When the temperature of a face section increases, inner pressure is generated in the sealed coolant 9 by the thermal expansion and carburetion of the coolant 9. This pressure presses and expands a soft bellows 18 and volume expansion components are absorbed in the bellows. The volume of the pressed and expanded components pushed out the air of a notched section 14 into atmospheric pressure through a ventilating hole 19 and as a result the internal volume is kept in stationary status. Besides, even if a bubble is generated in the sealed coolant 9, the bubble is smaller in specific gravity than liquid, the bubble floats and is collected to the bellows assembly body 16.

Title: Manufacture of trigger element
Inventor: NAGAI NOBUTAKA
IPC: H01L29/74
Filed: 1988-04-30
Abstract: PURPOSE:To enable the ON-voltage control by changing bulk concentration and junction depth by introducing the impurity of the same conductivity type as the bulk of a P-N junction, into the junction part. CONSTITUTION:In a P-type semiconductor substrate 1, a high concentration P-type impurity layer 2 is formed to a half depth of the substrate, and then N-type impurity layers 3, 4 are formed on the surface and the rear, respectively. P-type impurity is selectively diffused in the N-type impurity layer 3 of the surface, and a P-type impurity layer 5 is formed. By forming the whole part in a mesa type, a PNPN element, i.e., a Schockley diode is formed. In this manufacturing method, the breakover voltage is determined by the breakdown voltage of a PN junction in the junction part between the P-type impurity layer 2 and the N-type impurity layer 3. Said breakdown voltage is determined by the bulk concentration of the junction part. Thereby, the fine control of ON-voltage is enabled, by changing only the bulk impurity concentration of the junction part and the junction depth, without using semiconductor substrates having different impurity concentration.

Title: Resin-sealed component
Inventor: YOSHIDA SUSUMU
IPC: H01L21/48
Filed: 1986-05-14
Abstract: PURPOSE:To prevent lead pins projected externally from sealing resin and the sealing resin from separating at boundary therebetween by coloring the parts of the pins at least at the side of the resin with a color easily absorbing heat rays. CONSTITUTION:Lead pins 5 are projected externally of resin 4, and soldered partly at 7 to a circuit substrate to be electrically connected. The parts 6 of the pins 5 at the side of the sealing resin 4 is colored, for example, with a color for easily absorbing heat rays except the soldered parts 7 of the pins 5. In other words, since the parts 6 of the pins 5 are colored with black, the infrared ray radiating energy absorption rate of the colored part of the pin 5 is enhanced at the time of refeeding the solder with infrared rays to approach the temperature rise of the pin 5 to that of the resin. Thus, the thermal stress of the boundary of the pin 5 and the resin can be alleviated to prevent the pins 5 and the resin from separating at the boundary therebetween.

Title: Variable sensitivity detection method of substance to be detected using crystal oscillator
Inventor: OSANAWA RYUICHI
IPC: G01N5/02
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To make adjustable the detection sensitivity by adjusting the temperature of gas or liquid to be inspected by circulating it in a temperature- controlling device and then bringing it into contact with a detector that has been adjusted to be at the same temperature. SOLUTION: A detector being used is a crystal oscillator with a covering film that has an adsorption property for a substance to be detected on a surface. In the case of temperature control, the temperature generally ranges from -15 to 45 deg.C. However, when the detector is maintained at the low-temperature side, the amount of adsorption of a substance to be detected increase, so that the detection sensitivity improves. As the temperature, a temperature that is lower than a room temperature is adopted. Also, as a method for adjusting temperature, the detector is adjusted to a specific temperature by accommodating the detector in a box or the like, and for example gas or liquid that has been adjusted to a specific temperature in advance is brought into contact with the detector.  As a temperature-controlling device, a conduit coil or the like being arranged in a constant temperature room is adopted.
