Title: Production of aqueous solution or slurry of metal salt of maleic anhydride copolymer
Inventor: MUROI YOSHIYUKI
IPC: C08F222/06
Filed: 1990-06-27
Abstract: PURPOSE:To produce easily and inexpensively an aqueous solution or slurry of a metal salt of a maleic anhydride copolymer by copolymerizing maleic anhydride with a copolymerizable vinyl monomer in a specified organic solvent, adding a metal (hydr)oxide and water to reaction mixture, and reaction them under heating while distilling off the organic solvent. CONSTITUTION:Maleic anhydride is copolymerized with at least one vinyl monomer copolymerizable therewith (e.g. styrene) in an organic solvent which can dissolve these monmers but cannot dissolve the obtained copolymer (e.g. toluene). A metal hydroxide or a metal oxide (e.g. ZnO) and water are added to the obtained copolymer slurry and reacted under heating while distilling off the organic solvent. In this way, an aqueous solution or slurry of a metal salt of a maleic anhydride copolymer is obtained. The obtained aqueous solution or slurry can desirably be used as an adhesive, a nonburning coating agent, a cement dispersing agent or the like.

Title: Keyboard device
Inventor: HIBI KENJI
IPC: G06F3/02
Filed: 1985-07-31
Abstract: PURPOSE:To use a keyboard device properly in accordance with uses of a personal computer and a word processor and the like and to improve maneuoperability by using both front and back surfaces of the keyboard effectively. CONSTITUTION:Key switches S1-S12 for the personal computer and key switches S13-S24 for the word processor are formed on the front and back surfaces of the keyboard respectively. When the switch S1 or S12 is depressed, an 1-CPU 41 detects the depression through a scanning signal line 411 and a return signal line 414 and informs the detected result to a body side CPU. A key switch S0 is a switch for discriminating the front or back sides of the keyboard and its information is also informed to the body side CPU. The body side CPU discriminates the effective surface of the keyboard from the state of the switch S0 and detects the depressed switch out of the switches S1-S12. Thus, the keyboard device can be properly used in accordance with the use and the operability can be improved.

Title: Air conditioning device
Inventor: HORI MICHIMASA
IPC: F24F13/15
Filed: 1983-09-14
Abstract: PURPOSE:To realize the comfortable air conditioning by controlling the radiant heat emitting from a wall by a method wherein a blow-off direction converter is operated by an evaluation circuit to evaluate the output signal sent from a wall temperature sensor. CONSTITUTION:The hot air is blown off from a blow-off port as indicated with the arrow A so as to heat room air first of all. After twenty minutes or so, the air temperature in an air-conditioned room 2 is sensed by a room temperature detector 27. When said sensed air temperature reaches the set value set by a room temperature setter 26, a compressor 12 is brought into the stage to repeat the ON-OFF action. An evaluation circuit 23 is brought into actuation only when this stage is established and energizes a coil 22 by closing a relay 21, when the difference between the temperature of a wall 6 and the set value set by the room temperature setter 26 exceeds a limit value (such as about 6-8 deg.C). Accordingly, a solenoid plunger 11 is attracted and a connecting rod 10 is pulled. As a result, a blow-off direction converter 9 is changed over in order for air to blow off in the direction towards the wall 6 as indicated with the arrow B.

IPC: F24F11/02
Filed: 1985-08-02
Abstract: PURPOSE:To make it possible to respond to the change of ambient temperature of equipment, by providing two hot air discharge fans for discharging heat of intake air for a air-cooled condenser, and arranging to stop one of said fans when the ambient temperature falls by means of a sensor provided on the intake surface of said air-cooled condensor. CONSTITUTION:Intake air for condensation 5 becomes blow-off air for condensation 16 and is discharged by means of discharge fans 18 and 19 as discharged hot air 17 from the inside of temperature control unit box 22 to the outside. Because of a high resistance of closely formed enclosure 15 for refrigeration cycles, in the case of high ambient temperatures the pressure of high pressure part rises, resulting in decreased rate of condensation and defficiency in the capacity, necessitating the operation of discharge fans 18 and 19. On the other hand, in the case of low ambient temperatures. flow rate of intake air for condensation becomes so large that stable operation can not be maintained owing to such troubles as liquid compression, etc., as a result, sensor 21 is mounted on the intake surface of condenser 21 to stop discharge fan 18 by means of thermostat 20 associating with said sensor.
