Title: Method and device for measuring flow rate
Inventor: AKANO SHINICHI
IPC: G01F1/60
Filed: 1982-03-19
Abstract: PURPOSE:To measure the flow rate accurately at a high SN ratio, by varying an exciting current in response to a flow speed, and obtaining the speed from the variation. CONSTITUTION:An electromotive force corresponding to the flow speed of fluid is generated at detecting electrodes EDa and EDb in a pipe P and applied to an amplifier AMP1. A one polarity pressure signal e1 is compared with a reference voltage es in a comparator amplifier CA1 through a resistor R1. Based on a differential output e2, a current I is imparted to an exciting coil CL so that the differential output e2 becomes zero through a comparator amplifier CA2 and a transistor Q. AT this time, a dividing circuit DC receives a signal corresponding to the exciting current I from an inverted input terminal (-) of the comparator amplifier CA2 and outputs an output signal corresponding to the flow speed which is obtained from the inverse number of the value of the signal I. Since the SN ratio at a low flow speed becomes high, the flow rate can be measured accurately.

IPC: H04M1/2745
Filed: 1987-02-27
Abstract: PURPOSE:To simplify the operation of a telephone set by a caller by selecting one of opposite terminal numbers stored in a storage means and dialing the number automatically after the dialing is intermitted automonously when a busy tone is detected. CONSTITUTION:When a busy tone is detected by a busy tone detection circuit 5, it is reported to a CPU 13. In case of on-hook dialing, the CPU 13 changes the connection of a voice switch circuit 12 to the position of contact a-b to prevent a busy tone from being spoken loudly by an alerting circuit 9. In case of receiving the report for the detection of busy tone, the CPU 3 opens once a loop switch 2 to cancel the DC loop thereby informing the aborting of the dialing to a subscriber exchange. Then the loop switch 2 is closed again and the DC loop is generated, a redial number stored in a RAM 14 is read and the number is redialed by a dial circuit 3.

Title: Air conditioner
Inventor: NAKAMURA TAKASHI
IPC: F24F1/0063
Filed: 1981-03-26
Abstract: PURPOSE:To prevent the lowering of heat exchange efficiency  due to localized air flow, by changing the degree of opening of an air inlet to make the air flow distribution to a heat exchanger uniform. CONSTITUTION:The inlet 15 includes a first inlet 17 and a second inlet 18, and is integrally molded as a part of a front panel 11. The spaces of the grill 19 of the first inlet 17 are made small to increase the resistance aginst the air to be sucked, whereas the spaced of the grill 20 of the second inlet 18 are made great to decrease the resistance against the air to be sucked. When a cross flow fan 14 is operated, generally the air flow adjacent the upper part of the heat exchanger 16 is larger when compared with the lower part thereof since it is located near the fan 14, but by the presence of the first inlet 17, the air flow through the second inlet 18 becomes large accordingly. Thus, the distribution of air flow through the heat exchanger 16 is made apporximately uniform, and since the front panel 11 is integrally molded, the cost for the production is reduced.

Abstract: PURPOSE:To prevent the temperature rise and burning of a motor by stopping the motor for a preset time if the current of the DC control motor to follow the target value is kept at the preset duty ratio or higher for a prescribed time or longer. CONSTITUTION:An exhaust control valve 38 is driven to be opened or closed by a DC servo-motor 42 via a wire 40. A CPU 48 reads out from a ROM 50 the data corresponding to the engine rotating speed detected from an ignition circuit 46 and calculates the target opening of the control valve 38.

The CPU 48 monitors the duty ratio of the motor current and stops the motor 42 for a preset time if the preset duty ratio or more is continued for a prescribed time or longer. Accordingly, a large motor current is prevented from flowing continuously exceeding the rated current.
