Title: Ringing trip circuit
Inventor: HASHIDA MITSUYOSHI
IPC: H04Q3/00
Filed: 1981-07-08
Abstract: PURPOSE:To reduce malfunctions and to make the circuit small-sized, by detecting how the current value of an AC voltage at the zero crossing time is related to positive and negative thresholds to decide whether a DC current exists of not. CONSTITUTION:Voltage comparators 4 and 8 which compare a current value with positive and negative thresholds respectively are provided, and the presence or absence of a DC current is decided on a basis of the relation between an AC voltage at the zero crossing time and positive and negative thresholds. Thus, even if phases of the voltage and the current are shifted somewhat from each other, malfunctions are not generated.

Title: Oxygen concentration detection device
IPC: G01N27/404
Filed: 1992-03-31
Abstract: PURPOSE:To compensate deterioration with time properly by providing a means, etc., for generating measurement oxygen concentration data and then using an average output of the oxygen sensor output at that point and the reference output by that time as a new reference output. CONSTITUTION:It is judged whether a minute carry is generated or not and an amplification circuit 7 and an A/D conversion circuit 8 are driven when the minute carry is generated for measuring oxygen concentration and then the measurement data is stored in a RAM 9. Then, the oxygen concentration data value which is measured this time is subtracted from the reference oxygen concentration data value which is set to the RAM 9 for obtaining a level data and then the level data is set to the RAM 9. Then, it is judged whether the measurement oxygen concentration data is larger than the reference oxygen concentration data value or not. When the level data of the RAM 9 is less than 1, oxygen concentration display bodies 11a-11j are lit entirely and then gradually turned off as the oxygen concentration is low and the level data value increases. After the level data display processing, a date data and a current time data appear on a display 11.

Title: Optical disk player
Inventor: MAGAI MITSUTOSHI
IPC: G11B7/085
Filed: 1984-05-25
Abstract: PURPOSE:To prevent collision of an objective lens with a signal recording surface when a focus pulling back operation is inappropriate, by moving a lens means under a condition where the lens means is at the adjacent position of the central part of a disk and excessive approach of the lens means to the signal recording surface is prevented. CONSTITUTION:In case where a just focus condition is not detected and the pulse Po from a zero-cross detecting circuit 17 is not obtained in the course of focus pulling back operation, an objective lens 7 is stopped when a focus pulling back voltage Vfo reaches a positive limit level +E2. The level +E2 of the voltage Vfo is previously set in such a way that the lens 7 is stopped before it contacts with the signal recording surface of an optical disk after passing through a position where the lens 7 is set to the just focus condition.

Title: Mixed gas feeder of carburretor of car internal combustion engine during deceleratation
Inventor: KAMIMURA HITOSHI
IPC: F02M7/00
Filed: 1981-07-09
Abstract: PURPOSE:To improve the feeling of acceleration by reducing NOx by interlocking the shift detecting mechanism of a change gear with mixed gas increasing mechanism and by stopping the action of the mixed gas increasing mechanism and by stopping the action of the mixed gas increasing mechanism at the time of change gear shifting during acceleration. CONSTITUTION:The air is gradually introduced into a diaphragm chamber 15 by the action of an orifice 13a when a steady running state is transferred to a decelerating state, permitting a throttle valve 8 to be slowly and entirely closed. Hereby, the discharge of HC is reduced. Moreover, a clutch detecting means 19a is turned on when the change gear (drawing omitted) is shifted for acceleration, so that a control valve 14 cutts off a negative pressure passage 14b to cause the air to be introduced into the diaphragm chamber 15 and the throttle valve 8 to be abruptly and entirely opened. Moreover, this causes a pump guide 22, a pump chamber 25 and a pump nozzle 30 to be actuated via a throttle 1 to permit the amount of fuel to increase. Hereby, it is possible to increase the feeling and to reduce NOx.

Filed: 1994-05-20
Abstract: PURPOSE:To obtain an inorganic powder which is free from aggregation and excellent in mixability with a resin by coating an inorganic powdery material with a specific coating fluid comprising a partial hydrolyzate of an alkoxysilane as the base. CONSTITUTION:A liquid comprising a partial hydrolyzate of an alkoxysilane as the base, a curing catalyst, and water in an amount which theoretically suffices to completely hydrolyze the hydrolyzate is regulated so as to have a pH of 3 or lower and then aged. Water is added thereto to obtain a coating liquid. Tetramethoxysilane is preferred as the alkoxysilane, because it tenaciously adheres to an inorganic powder.

Title: Brush for washing narrow-mounted container
Inventor: FUKUSHIMA KAZUYUKI
IPC: A47L17/00
Filed: 1989-04-26
Abstract: PURPOSE:To easily insert a brush to a narrow-mouthed container and to easily wash the bottom of the bottle by using a shape memory alloy, which is deformed by heat, for an opening and closing part between a main body part and a washing elastic part and the washing elastic part. CONSTITUTION:The brush is normally set in a state that an opening closing part 2 is closed. Then, the brush can be easily inserted from a bottle port part 53 of a feeding bottle 5. A main body part 1 is equipped with the opening and closing part 2, which is composed of the shape memory alloy, to be opened by heating in an interval to a washing elastic part 3. Accordingly, the opening and closing part 2 is opened at 90 deg. by hot water 6 in the feeding bottle 5. Since the washing elastic part 3 is composed of a linear body 33 of the shape memory alloy to be bent by heating in correspondence to the bottom part shape of the feeding bottle 5, the washing elastic part 3 is bent in the same shape as the opening and closing part 2 by the hot water 6 in the feeding bottle 5. A nylon-made brush part 35 is fitted around the linear body 33. Thus, a solidified substance 7 of milk remained in a bottle bottom 51 of the feeding bottle 5 can be easily washed and removed by the washing elastic part 3.
