Abstract: PURPOSE:To enhance an integration, a speed and to reduce power consumption while shortening a period from a logical design to the end of a layout design by designing and verifying by a logic simulation with a delay using real wiring capacity until a delay time falls within a predetermined range. CONSTITUTION:A logical design is initially executed, verified by a logical simulation with a delay using a virtual wiring capacity, and designed in a layout by an automatic disposition wiring.

Title: Electric bulb and lighting system
Inventor: SUWA TAKUMI
IPC: H01K1/32
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To reduce an amount of infrared rays to be radiated outside of a bulb, prevent thermal deterioration of exhibition goods, restrict an evaporation speed of tungsten, ensure high luminescence characteristics and extended service life by sealing inert gas containing xenon in the bulb and providing a thermal ray absorption film on a surface of the bulb. SOLUTION: When a bulb L is turned ON, a filament 4 is heated, a large amount of infrared rays are radiated together with visible light, a majority of the visible light of the light radiated from the filament 4 transmits a bulb 1 and a thermal ray absorption film 5 and is radiated to the outside. A majority of the infrared rays incident to the bulb 1 is absorbed by the thermal ray absorption film 5, and a small amount is radiated to the bulb 1.  Since xenon with its greater atomic weight and lower thermal conductivity than those of argon or crypton is mainly contained as inert gas in the bulb 1, evaporation speed of tungsten is restricted, an amount of infrared rays to be radiated outside of the bulb is reduced, thermal deterioration of the exhibition goods is prevented, evaporation speed of tungsten is restricted, and high luminescence characteristics and extended service life is ensured.

Title: Pressure detection circuit
Inventor: UEDA SHIGEKI
IPC: G01L9/12
Filed: 1988-10-14
Abstract: PURPOSE:To enable a better detection with a stable accuracy by providing a capacitor connected to a detection electrode capacitance at one end and an earth at the other end to make a charged/discharged current flow to the capacitance from both positive and negative power sources of a saw-tooth wave generation circuit. CONSTITUTION:One end of a capacitor 7 is connected to an output end of a saw-tooth wave generation circuit 1 using an operational amplifier while the other end thereof is connected to an earth. The operational amplifier is operated with both positive and negative power sources + or -B. With such an arrangement, since, if a change takes place in a floating capacitance of a circuit, charged or discharged current flows through the capacitor 7 from the power source against the stable frequency of the saw-tooth wave can be maintained. Only connecting the capacitor 7 with a slight capacity value can suppress the change to about one-tenth thereby enabling increase in resolving power by one digit as compared with that in the past, and as a consequence, can expand a measuring range as much. However, considering that an abnormal oscillation occurs as the capacity of the capacitor 7 increases, there exists an optimum range for the capacity of the capacitor 7.

Title: Code reproducing device with automatic threshold value adjusting function
Inventor: MATSUMURA KAZUO
IPC: H03K5/08
Filed: 1984-12-10
Abstract: PURPOSE:To reduce fluctuation of a pulse width in a single-pulse state by connecting two terminals of a transistor (TR) to two input terminals of a comparator so that one is connected through a capacitor and the other is connected directly. CONSTITUTION:A signal inputted to a TR31 is amplified by the TR on a uninverted and an inverted basis, and those two signals are inputted to the two input terminals of the comparator 32; one signal is inputted through the capacitor to obtain a differential waveform and shorten a rising and a falling time, and the other signal is inputted to the comparator directly as its threshold voltage. A waveform at the opposite-phase input terminal 36 of the comparator is the differential waveform of the waveform at an input terminal 33 and shorter in rising time and falling time than a waveform at an input terminal 33 and the two input signals of the comparator 32 change in polarity symmetrically, so variation in pulse width is reduced. Further, the input signal is amplified by the TR and variation of the differential waveform is made larger than that of the threshold voltage to shorten the time of rising and falling to the threshold voltage, thereby further reducing the pulse variation.

Title: Capacitor and manufacture thereof
Inventor: AOYANAGI TAKUJI
IPC: H01G13/00
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To make it possible to form gaps of a constant width with high accuracy even by the so-called dip coating that both ends of a capacitor element are dipped in a conductive paste to coat the conductive paste on both ends of the element and moreover, to prevent the exterior diameter of an insulating coating from being made large and also to make it possible to obtain the high value of the electrostatic capacitance of a capacitor. SOLUTION: A capacitor is formed into such a structure that such step parts 15 and 16 as to fall in both sides of parts, which form gaps 13 provided in a capacitor element 11, are formed and when a conductive paste is performed a dip coating, the coating of the paste is stopped in the parts by the fall-in of these step parts 15 and 16. By adhering a conductor film also on these step parts 15 and 16, the edges of electrodes 12 and 12, which consist of the conductor film, not only are butted to each other holding the gaps 13 between them but also opposed electrodes are formed on the parts of the step parts 15 and 16 in the electrodes 12 and 12, whereby the higher value of the electrostatic capacitance of the capacitor is obtained. Moreover, when a resin is applied on the parts for forming an insulating coating 14, this resin intrudes into the step parts 15 and 16.  As a result, the external diameter of the insulating coating 14 is not made large extremely.

Title: Simulated testing method for extension testing device
Inventor: AKAO HIROSHI
IPC: G01M99/00
Filed: 1990-09-29
Abstract: PURPOSE:To make a servo motor compact in its size and light in its weight by offsetting a horizontal force produced by the mass of a test sample body with a balance weight so as to limit the load applied to a horizontal-direction control servo motor only to the horizontal--direction component of the force produced by extending motion of the test sample body. CONSTITUTION:When a test body 2 is separated from a part fixed to an artificial satellite 1 and subjected to extending motion in an environment under gravitation on the ground, a wire 3 for hanging the test sample body 2 is given by a servo motor 10 a tensile force which can hang a mass equivalent to that of the test sample body 2, thus the test sample body 2 being placed under simulated non-gravity state. Namely, a variation in tensile force taking place when a reaction force occurs in the wire 3 due to the extending motion of the test sample body 2 is detected by a tensimeter 9, and the servo motor 10 is controlled by a controller so that the variation in tensile force becomes zero. In this case, a balance weight 27 is connected by a wire 11 to the output shaft of a horizontal-direction servo motor 12 so that only the variation in tensile force is applied as a load to the horizontal-direction servo motor 12.
