Patent JP-H03117905-A (JP)
Title: High frequency balance mixer
Inventor: ABE SHUJI
IPC: H03D7/14
Filed: 1989-09-30
Abstract: PURPOSE:To reduce the distortion and to eliminate a need of parts such as a transformer for unbalance-balance conversion by converting an unbalance signal to a balance signal by a differential amplifying circuit and supplying it to a double balance mixer. CONSTITUTION:A balance mixer consisting of diodes 10 to 13 mixes signals from a secondary winding L2 to generate an IF signal, and this IF signal is converted to an unbalance signal by a transformer 14 for balance-unbalance conversion and is led out from a terminal 15. The unbalance RF signal led into an input terminal 1 is inputted from the base of a transistor TR Q11 and is differentially amplified and is outputted as a balance signal from collectors of TRs Q11 and Q12. Since the unbalance signal supplied to the input terminal 1 is converted to the balance signal by a differential amplifying circuit 20 in this manner, the transformer for unbalance-balance conversion is unnecessary, and even-order distortions are cancelled because having the same phase and do not appear in the IF signal.

Patent JP-S61113183-A (JP)
Title: Semiconductor memory circuit
Inventor: AOYAMA KEIZO
IPC: G11C11/417
Filed: 1985-11-16
Abstract: PURPOSE:To reduce the access time and electric power consumption by changing apparently mutual impendances of load transistors due to information at access and controlling a conventional steady current in accordance with the information. CONSTITUTION:When a memory MC is accessed through a word line WL in the condition where the transistors Q5 and Q6 are set to sides L and H, respectively, first a current (i) rises. Before the current (i) rises, the logical level of a bit line BL is at 'H' level. After the level is sufficiently converted by a level converter LC1, it is impressed to the gate of a load transistor Q1 as a sufficiently high 'H' level. Then the load transistor Q1 satisfactorily maintains the on-state. If the memory MC is accessed in said on-state, current (i) quickly rises. Then the current (i) is led to a ground (GND) through transistors Q3 and Q5, and the logic of the bit line BL drops toward 'L' to turn off the load transistor Q1 quickly.

Title: Kana/kanji converter
Inventor: AIHARA KAZUO
IPC: G06F17/22
Filed: 1990-09-26
Abstract: PURPOSE:To hold the priority of the notation used frequently by providing a setting means for setting whether a learning means is applied or unapplied, based on a user's instruction with regard to a homonym selected by a selecting means. CONSTITUTION:By a conversion key, an input character-string is converted to a KANA (Japanese syllabary) and KANJI (Chinese character) mixed sentence, and also, a candidate of the KANJI is displayed. By a candidate selection key, a candidate selection processing is executed. In this case, whether a learning cancel key is depressed or not is decided. When it is depressed, the processing is finished. Unless it is depressed, the learning processing is executed, and the word subjected to learning processing is registered in a character registering part 15. For instance, when the conversion is executed by reading 'KOU', 'KOU (high)' is obtained. When it is not desired to omit the priority of the notation of 'KOU (work)' and 'KOU (term)' against 'KOU', a user depresses a learning cancel key. In such a way, when the conversion is executed by 'KOU' again, the 'KOU (work)' is displayed as a first candidate.

Title: Filter for electrostatic precipitator
Inventor: ARAKI KAZUHIRO
IPC: F24F7/00
Filed: 1990-09-25
Abstract: PURPOSE:To reduce a pressure drop and to increase air quantity by overlaping an electro-conductive meshed body electrostatically charged into polarities to adsorb an electrostatically charged dust onto the air permeable dust eliminating layer. CONSTITUTION:When air is contaminated by smoking and detected by the detecting sensor 15, operation is started automatically and in the case of a heavy contamination, the amount of a suction air is increased to an appropriate level. When air is purified, suction air is decreased according to it and finally stopped automatically. Also, even by the output of a human body detection sensor 14, the mode of operation is switched and controlled as well. This switching control of the operation mode of the air purifier corresponds to the output of the human body detecting sensor 14 and the contamination detecting sensor 14 are operated by the controller. By this means, the pressure drop is reduced and the increase in air quantity is attained.

Title: Photographic printing and developing device
Inventor: MATSUMOTO FUMIO
IPC: G03D3/00
Filed: 1987-10-13
Abstract: PURPOSE:To stably convey photographic paper by switching the rotating direction of an air blower which is arranged between a photosensitive material supply part and a development part to admit outside air and discharge inside air when set requirements are met. CONSTITUTION:The outside air is admitted to between the photosensitive material supply part and development part 14 through the rotation of the air blower 42, which reverses to discharge the inside air. When the inside air is discharged, wet air in the development part 14 flows to between the photosensitive material supply part and development part 14. When the atmosphere conditions between the photosensitive material supply part and development part 14 decrease below set humidity, a control means switches the rotating direction of the air blower 42 to discharge the inside air. Consequently, the atmosphere conditions between the photosensitive material supply part and development part 14 are set to humidity suitable to the conveyance of photosensitive paper 18 throughout four seasons and the photographic paper 18 is conveyed stably without exerting any adverse influence upon the conveyance of the photosensitive paper.

Abstract: PROBLEM TO BE SOLVED: To easily increase a dissolved oxygen quantity in a culture pond, etc., by operating an underwater pump, ejecting water from the nozzle to generate negative pressure in a mixing chamber, sucking the air from a sucking pipe opened to the air to be mixed with a high speed of water stream, and ejecting it into the water. SOLUTION: An aspirating aerator is constituted of a sucking device S, the underwater pump P and a support means G, the underwater pump P being energized and operated, then the water being unsaturated with oxygen at the middle and lower layers of the culture pond is sucked and ejected through the nozzle B via a tube A in a high speed. By this ejection, negative pressure is caused in the mixing chamber C and the air is sucked through the sucking pipe D opened above the water surface, and introduced into the mixing chamber C through a spherical cavity E and a focusing tube F. Here, the oxygen in the air is thoroughly mixed with the high speed water stream and rapidly dissolved into the water and ejected as oxygen saturated water, then the dissolved oxygen quantity in the culture pond is increased.
