摘要： PURPOSE:To efficiently carry out the introduction of fresh air when operating a cooler by setting a target intake air temp. at the time of introducing inside/ outside air into a duct casing, and adjustingly controlling the opening of an inside/output air switchover door so as to obtain said target intake air temp. CONSTITUTION:A control unit 13 determines a target intake air temp. after determining an inside target control temp., to adjust the opening of an inside/ outside air switchover door 5 based on the deviation between the intake air temp. of an actual inside/outside air introduced into a duct casing 1 and the target intake air temp. When a cooler is operated lowering an intake air temp. lower than a target intake air temp., the door 5 is opened to introduce an outside air, increasing the intake air temp. of the inside/outside air. And, the adjustment of the opening of the door 5 is repeatedly carried out so as to make the difference between both temperatures zero. Thereby, the rate of opening the outside air introducing side of the door 5 becomes large, efficiently introducing fresh air.

摘要： PURPOSE:To obtain the optimum temp. and air quantity by detecting the temp. and air velocity of a blow-out air by means of a sensor provided on each blow- out port and controlling an air mix door for controlling each air conditioning zone and mode doors provided on said blow-out ports. CONSTITUTION:After introducing the open air by operating a door 5 by means of an actuator 10, the rate of air which passes through bypasses 1c, 1d to air which passes through a heater core 4 is adjusted, to control the temp. of airs which blow out of upper and lower parts respectively. In this case, signals from each of room-temp., open-air, and sun-shine sensors 21-23 as well as signals from blow-out temp. sensors 15, 17,19 and air velocity sensors 16, 18, 20 are inputted into a microcomputer 28 via an A/D converter 29. And, air mix doors 6, 7 are controlled via actuators 11, 12 and mode door actuators 13, 14 are controlled by means of the operation and processing of the microcomputer 28.

摘要： PURPOSE:To optimize the distribution of temperature and capacity in each duct, by constituting an air conditioner so as to control the blowoff temperature and the blowoff capacity by means of each of separate operation parameters, in case of the air conditioner provided with plural cab blowoff ports. CONSTITUTION:Those data of cab vertical temperatures 31a and 31b, outsidfe temperature 35, upper and lower blowoff temperatures 32 and 33, solar radiation quantity 36, and setting temperatures 61 and 62 are al inputted into a controller 37. And, desired cab temperature Tac is set from these setting temperatures 61 and 62, the outside temeperature 35 and the solar radiation quantity 36, while blowoff desired temperature is set from this desired temperature Tac, the outside temperature 35 and these cab vertical temperatures 31a and 31b, and each opening of hot water valves 19c and 19d is controlled. And, if the outside temperature 35 is made than the setting value, a through hole 43d is fully opened, but when it is blow the setting value, each opening of air-mix doors 43a and 43b is controlled from a difference between knee part desired temperature and knee part blowoff temperature 43. With this constitution, conditioned air at optimum temperature and capacity is able to be blown off.

摘要： PURPOSE:To prevent an erroneous operation on starting by constructing the captioned clutch type driving part protecting device in such a way that a clutch releasing operation does not take place before a certain period of time has elapsed after operating said clutch. CONSTITUTION:The coil 5 of an electromagnetic clutch 3 is electrified, causing a rotor 7 to attract a disk 14, to connect an engine 8 to the shaft 9 of a compressor 1. The speeds of rotation of the rotor 7 and the disk 14 are detected by pickups 17, 18, and compared with each other by means of a processing circuit 19, to judge whether there is a slide, based on difference above a certain number of rotation and the on and off condition of the clutch 3. When judged that there is a slide, processing is held for a certain period of time and, when the sliding condition still continues, a command is outputted for the clutch 3 to be turned off. Due to this construction, an erroneous operation can be prevented at the time of starting.

摘要： PURPOSE:To eliminate slip of a clutch by changing-over an individual operation of an exciting coil to parallel operation at the rotational frequency about torsional resonance point of a shaft. CONSTITUTION:When an electric current is applied to an exciting coil 4, a starting exciting coil 401 and an steady-state exciting coil 402 are operated parallel, and a close magnetic path S is formed among a stator 1, an input rotor 2 and an armature 10, thereby to generate sucking force between a friction plate 204 of the input rotor 2 and the armature 10, so that the armature 10 is adsorbed to the friction plate 204 against the force of a plate spring 902. When the starting state is completed, only a steady-state exciting coil 402 is individually operated by a delay circuit 13, so that the turning force of the armature 10 is transmitted to a rotary shaft 8 through a plate spring 902, an output rotor 901 and a hub 9.

摘要： PURPOSE:To improve a high-load, high-speed characteristics, a resistance to abrasion and a resistance to seizing by a method wherein a sintered body layer, formed on the swash plate side surface of a slipper base member of steel, is constituted of the principal constituent of Fe and a solid lubricating agent is contained thereinto. CONSTITUTION:The base member 9 of the slipper 3 is made of steel having a tensile strength higher than 30kg/mm. and the surface of the base member 9 is provided with a coating layer 10 consisting of metal salt or metal sulfide. The surface of the base member 9 at the side of the swash plate 2 is formed with the sintered body layer 8 of 0.1-0.7 thick, which is consisting of 1-10wt% of Cu, 8-30wt% of Pb, 0.5-5wt% of graphite of solid lubricating agent and a balance of Fe. According to this method, the resistance to abrasion becomes prominent even under the high-speed sliding condition, the durable time against seizing becomes longer even under a condition that lubricating oil does not exist temporarily, and the durability as well as the reliability may be improved compared with conventional compressors.

摘要： PURPOSE:To control the capacity of the titled device in order to save energy by a method wherein an opening is provided on the way of a cylinder stroke to change the effective stroke of the cylinder by the opening and closing of the opening. CONSTITUTION:When a solenoid valve 11' is retracted and the opening 10' is opened, the opening 10' communicates with a swash plate chamber 5, communicating with low-pressure chambers 6, 6', and the stroke becomes S2 substantially. Accordingly, the discharging capacity of the compressor becomes S2X(pi/4)d1 . Thus, the capacity of the compressor may be controlled arbitrarily and easily by the operations of the solenoid valves 11, 11' and the energy may be saved.
