Title: Analog/digital converter
Inventor: ITO MASAO
IPC: H03M1/06
Filed: 1994-09-14
Abstract: PURPOSE: To output digital signals close to a correct value and to convert analog signals into the digital signals without large errors by correcting an erroneous output value even when comparator output signals are erroneous CONSTITUTION: When the output values of comparators CP1 to 7 are abnormal combinations, for instance, when the output values C1 to 7 are HHHHLLL at the normal time, the output value C4 of the comparator CP4 is L when it should be H and the output value C5 of the comparator CP5 is H when it should be L, for instance. At the time, among the output values from a majority logic unit MU to an encoder EN, only the output value J5 is H and the others are L and output is performed. Thus, the correct digital codes of 001 are outputted as the output codes D1 to 3 of the encoder EN. Also, at the time of the other abnormal combinations, the output codes become 101 or 110 and become the values close to the normal output codes.  Thus, by using the unit MU, the values close to the normal output codes are outputted from the encoder EN and the analog signals are converted into the digital signals without the large errors.

Title: Exhaust gas reheating cylinder
Inventor: OKADA SHUNJI
IPC: F23G5/00
Filed: 1996-08-03
Abstract: PROBLEM TO BE SOLVED: To improve odor or smoke removing effect of an exhaust gas reheating cylinder by turning the direction of jetting a flame of a burner in the tangential direction the same as the direction in which an exhaust spirals. SOLUTION: In this reheating cylinder, a burner 2 is arranged on a surrounding wall of a vertical type bottomed cylinder body 1 piercing it and an exhaust port 3 is provided to send an exhaust gas in the tangential direction near a lower end part of the surrounding wall while an exhaust gas outlet 4 is provided at the upper end of the cylinder body 1 so that the exhaust gas ascending spiraling within the cylinder body 1 is reheated. In this case, the direction of jetting a flame of the burner 2 is turned in the tangential direction the same as the direction in which the exhaust gas spirals. Therefore, as the exhaust gas comes in contact with the flame spiraling in the direction the same as that of the flame, a longer contact time can raise effect of removing soots and volatile odor thereby lowering the consumption of a fuel.  In addition, the injecting energy of the flame can promote the spiraling motion of the exhaust gas thereby allowing miniaturizing of a fan for feeding gas.

Title: Fluorescent lamp and lighting system
Inventor: HONDA HISASHI
IPC: H01J61/54
Filed: 1994-09-16
Abstract: PURPOSE: To suppress the blackening (EC blackening) caused in a transparent conductive coating during lighting time of a fluorescent lamp by putting a mercury evaporating alloy in the tubular end part where the resistance is higher in a light transmissive air-tight container. CONSTITUTION: A transparent conductive coating 12 is formed in the inner face of a thin, long, tubular, light transmissive, and air-tight container 11, the resistance of the both tubular end areas is relatively higher than that of the middle area and the resistance of one end area of the tubular container is made to be relatively higher than that of the other end area. A mercuray evaporating alloy 18 is put in the tubular end side where the resistance is higher in the container 11. Consequently, at the time when mercury is deposited, the mercury is converged upon the tubular end part where the resistance is higher. As a result, even if mercury particles adhere to a phosphor coating near the tubular end part, due to the high resistance of the coating 12 near the part, slight discharge occurrence is suppressed and EC blackening can be suppressed.

Title: Magnetic disk device
Inventor: ISHIGAKI TATSUYA
IPC: G11B21/22
Filed: 1989-08-30
Abstract: PURPOSE:To apply fixed bias force to a carriage in a small setting space by banding a leaf spring, for which one end is fixed to the prescribed position of the carriage and the other end is fixed to a prescribed fixed part, near the rotational center of an actuator. CONSTITUTION:Since one end of a leaf spring 80 is fixed to a carriage 40 and the other end is fixed to the prescribed fixed part, the bias force is always applied to the carriage 40 by restoring force for the bend of the leaf spring 80. Since the rotation driving force of the carriage 40 is interrupted by an actuator 50 when the rotation of a magnetic recording disk is stopped, the carriage 40 is rotationally operated so that a magnetic head 30 can be moved to a shipping area on the magnetic recording disk by the restoring force of this leaf spring 80. Thus, since the retract of the magnetic head 30 is executed by the leaf spring 80, the setting space is not required so much and the fixed bias force can be always applied to the carriage 40.
