Title: Composite signal demodulator
Inventor: SUZUKI TSUNEO
IPC: H04H40/45
Filed: 1984-12-24
Abstract: PURPOSE:To demodulate accurately an FM stereo and a sound multiplex broadcast by using an FM stereo demodulation as it is or applying sound multiplex demodulation processing on the said output depending on the presence of detection of a pilot signal component in an input signal. CONSTITUTION:An AM stereo demodulator 25 has a function to detect whether an input signal is an FM stereo signal or a sound multiplex composite signal by discriminating whether or not a pilot signal component exists in a signal fed to a terminal 24 and generates a detection signal K to a sound multiplex composite signal demodulator 26 when the signal is an FM stereo signal. When the signal K is applied, the demodulator 26 leads the FM stereo demodulation output signal from the demodulator 25 to output terminals 27, 28 as it is. When the signal K is not detected, the demodulator 26 leads the output of the demodulator 25 to a matrix circuit, detects a sub signal component from the output of the demodulator 25, discriminates whether the broadcast is a stereo broadcast or other broadcast, a matrix circuit applies sound multiplex demodulation processing and outputs a demodulation signal of sound multiplex broadcast to the terminals 27, 28.

Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a gate for preventing the deterioration of a gate insulating film, and for preventing the etching of a semiconductor substrate by using a film with carbon as main components, and using a dry etching method for patterning. SOLUTION: At formation a gate and gate wiring at a semiconductor substrate, a film 4 with carbon as main components is formed on an insulating film 3 formed on a semiconductor substrate 1. A prescribed mask 6 is formed on the film 4, and the film 4 is worked and a pattern is formed. The film 4 is etched by dry etching using gas which does not contain halogens such as oxygen, nitrogen, carbon monoxide, and argon or the mixed gas. This etching is selectively stopped by the insulating film 3. The insulating film 3, such as SiO2, is etched by dry etching using gas which contains halogen, and the etching is hardly progressed in the dry etching using the gas which does not contain halogens.

Title: Bonding wire
Inventor: KURIHARA MASAAKI
IPC: H01L21/60
Filed: 1987-10-28
Abstract: PURPOSE:To give sufficient strength even in low load and a low ultra sonic output, and to prevent neck breakdown and the generation of a curl by forming a sectional shape to an ellipse. CONSTITUTION:The sectional shape of a bonding wire is formed to an ellipse. The wire can be joined so that the long diameter of the wire is made horizontal to the bonding surface of a semiconductor device particularly at the time of wedge bonding. Consequently, a joining area in the same extent as a conventional wire can be acquired even in low load and a low ultrasonic output. Since sufficient joining strength is obtained without damaging an Si chip and the quantity of deformation in the vertical direction of the wire is reduced, the strength of a neck is not also weakened, neck breakdown is difficult to be generated, and a curl is difficult to be generated because the direction horizontal to the bonding surface of the semiconductor device is used as a long diameter.

Title: Sealed lead-acid battery
Inventor: ASAI KENJI
IPC: H01M2/38
Filed: 1985-12-03
Abstract: PURPOSE:To eliminate concentration difference in electrolyte in a battery by sucking an electrolyte in a porous separator through a fine tube by using the variation in internal pressure in the battery to transfer the electrolyte. CONSTITUTION:A safety vent in a sealed lead-acid battery is opened to exhaust gas when the internal pressure of the battery becomes higher than the atmospheric pressure by overcharge, and on the other hand, during storage, the internal pressure becomes lower than the atmospheric pressure. The internal pressure of the battery changes in a wide range during use. When the internal pressure of the battery which is equal to the internal pressure of a container 6 is increased by charge, a valve 7 opens and the electrolyte in a porous separator 4 is sucked up through a fine tube 5, and retained in the container. When the battery is discharged or allowed to stand, the internal pressure of the battery is lowered than that of the container 6, and a valve 8 opens and the electrolyte in the container 6 is transferred to the bottom of the battery through a fine tube 9. Therefore, even if the concentration difference is produced in the battery, the electrolyte circulated and the concentration is kept uniform.

IPC: G06K15/02
Filed: 1992-10-13
Abstract: PURPOSE:To speed up a process and to reduce the load by uniformly separating respective characters corresponding to an optional character spacing set value and automatically kerning them. CONSTITUTION:Kerning information on respective fonts which has possibility to be arrayed right before, are set for respective fonts together with character data. The kerning information is so defined that when character spacing is 0%, a character contour comes into contact with one or plural points of coordinates of a last character contour; when a printing process is carried out with the 0% character spacing, respective characters of the alphabet are outputted in the contact state. Character spacing is set in a print control part at an optional rate based upon the constant value of the height of a font, etc., and when the character spacing is set to, for example 10%, each font is outputted with the spacing which is 10% of the height of the font. Therefore, complicated calculations for finding the spacing with a last character at every character is not necessary and the kerning process is automatically performed by the quantitative process.
