Title: Concave rearview mirror
Inventor: KUROKI MASAHIRO
IPC: B60R1/08
Filed: 1978-10-20
Abstract: PURPOSE:To accomplish wide expansion of the side view simply and accurately by employing a concave mirror for the rearview mirror of automobiles or the like. CONSTITUTION:A side-long concave mirror 4 with given dimensions is arranged at a specified position of automobiles or the like. This allows wider expansion of the side view 17 in the total view 16 as compared with the conventional convex rearview mirror when the driver 14 of automobiles or the like looks into the mirror. As the wider side view 17 only requires inward extention of the mirror from the side line of the car, this can reduce the danger of bloking the traffic by projection from the side of the car.

Title: Apparatus for controlling defrosting operation in refrigerating cycle in air conditioner
Inventor: SUGIO TAKASHI
IPC: F24F11/02
Filed: 1984-06-25
Abstract: PURPOSE:To reduce a generation of noise or vibration when a unit is changed over from a defrosting operation to a heating operation by a method wherein a first time measuring means for measuring a time elapsed by turning off a circuit of compressor and closing a four-way valve circuit in an indoor unit after a predetermined time is elapsed and a second time measuring means for similarly closing the circuit of compressor in the indoor unit after a predetermined time is elapsed are arranged. CONSTITUTION:When a sensing means 6 detects a releasing of condition of frosting during a defrosting operation, a four-way valve circuit contact point 8 is closed and then a four-way valve 5 is energized. A current sensor 7 may detect an energization to open the contact points 11 and 13 with a slight time delay of DELTAt after energization, the four-way valve 5 is set to a refrigerating cycle and then a compressor 1 is terminated to operate. At the same time, the contact points 17 and 18 are closed and the timer 15 measures a desired time t1, resulting in that the contact point 12 is closed to energize the four-way valve 5 and change-over the operation to a heating cycle. Subsequently, when the timer 16 measures a desired time t2, the contact point 14 is closed to operate the compressor 1 and then a heating operation is started. Since the delay in time DELTAt is sufficiently low as compared with an operating time of the four-way valve 5, a differential pressure across the four-way valve 5 is eliminated during the desired time t1 and then the noise and vibration when the four-way valve 5 is changed over are decreased.
