When the air conditioner is constituted as described above, since air which has been heated to high temperatures by the condenser 3 is not discharged in the room, it is possible to low the temperature in the full part of the room. Accordingly, even when one's body is not brought direct contact with cool wind from a discharge port 13, one can obtain pleasant cool feeling if one is in the room. Furthermore, dews attaching to the evaporator 5 are received from a dew receiving dish 8 into a dew water tank, and hence it is unnecesary to drive dews from the unit 1 to cast them aside. Since the single blower 7 for the evaporator is provided, noise is reduced.

Title: Dropout compensating circuit
Inventor: SASAKI HIROYASU
IPC: H04N5/94
Filed: 1983-05-13
Abstract: PURPOSE:To compensate completely a dropout produced in a reproduced video signal from a recording medium by inserting and connecting a signal delay means having a delay time in matching with the delay time of the detecting operation of at least a dropout detecting circuit to a reproducing video signal input path. CONSTITUTION:Since the delay time td of a delay video signal S5 is set slightly longer than the delay time td' of the detecting operation of the dropout detecting circuit 3, the dropout of the delay video signal S5 is generated with a slighted delay than a detection pulse S2, and its end point of time is slightly faster than the end point of the detection pulse S2 because the time width T' of the detection pulse S2 is set slightly wider than the generation period T of the dropout. Thus, a signal switching addition circuit 4 is controlled by the detection pulse S2 and the dropout compensation is applied to the delay video signal S5, then a video signal S3 whose dropout is compensated completely is outputted from the signal switching and addition circuit 4 independently of the delay in the detecting operation of the dropout detecting circuit 3.

Title: Controlling method for injection molding machine
Inventor: KOBAYASHI AKIO
IPC: B29C45/78
Filed: 1994-04-21
Abstract: PURPOSE:To regulate molding conditions in which a pressure in molds becomes suitable by discriminating a difference between an arrival time of a primary peak of the pressure and an arrival time of the primary peak of the pressure to become a standard, and so sending a signal from a controller to an injection molding machine as to coincide with the arrival time of the peak of the pressure to become the standard. CONSTITUTION:An arrival time of a primary peak of a pressure in molds to become a standard is previously set to a discriminator 3, an arrival time difference of the peak of the pressure in the molds is dispriminated, and viscosity of melted resin in the molds is estimated. For example, the pressure in the molds to become the standard is indicated by a curve (g), and the arrival time of the peak is indicated by a point G, while the pressure in the molds of actually measured value is indicated by a line (a). When the time of the peak is indicated by a point A, viscosity of the melted resin is low, and hence it is discriminated that the time is early. A support signal is sent from a controller 4 which receives the output signal from the discriminator 3 to an injection molding machine 2, regulated to lower a cylinder temperature, and a molding condition is so regulated that the pressure in the molds becomes suitable.

Abstract: PURPOSE:To inhibit tensile vibrations in a short time by inputting torque corresponding to a tension section to a torque regulator through a delay element. CONSTITUTION:A tension regulator 11 supplies a torque regulator 21 with a deviation signal between a tension-section torque set value tauT' and a tension section torque tauT. The torque regulator 21 is fed with the tension-section torque set value tauT' through a proportional grain 12 in order to quicken the follow-up of the actual value of the tension section torque to the tension-section torque set value. The tension section torque is output to the torque regulator 21 by positive feedback through a delay element 13 in order to inhibit tensile vibrations. A torque controller 2 controls a thyristor rectifier 3 in response to a deviation between a torque set value taua' and a current detecting signal ia. Accordingly, tensile vibrations can be suppressed by simple circuit constitution in a short time.
