Title: Measuring device of compression of housing lock level
Inventor: ENOMOTO KAZUO
IPC: G01M99/00
Filed: 1991-10-09
Abstract: PURPOSE:To obtain a measuring device of compression of a housing lock lever which reduces a frictional force between the housing lock lever and a compression jig and reduces measuring error caused by the force. CONSTITUTION:A roller-shaped contact fitting 19 is fitted rotatably to the fore end of a compression jig 18 and a connector 13 is disposed so that a housing lock lever 12 operates within a rotation surface of the contact fitting 19. When a head part 14 of the housing lock lever 12 is pressed by lowering the compression jig 18, the housing lock lever 12 is deflected with the head part 14 moved along a virtually circular-arc trace. On the occasion, the contact fitting 19 rolls on the head part 14 of the housing lock lever 12 and thereby a frictional force between the two parts 19 and 14 is prevented from being transmitted to the compression jig 19.

Abstract: PROBLEM TO BE SOLVED: To simultaneously adjust receiving speed volume and transmitting speed volume and to miniaturize the telephone system by means of commonly using a receiving speed volume adjusting key by adjusting receiving speed volume with the first operation of the receiving speed volume adjusting key and adjusting receiving speed volume and transmitting speed volume with the second operation. SOLUTION: A control circuit 10 controls a chennel and voice codec 5 based on the operation of an UP key 154 and a DOWN key 155 so as to increase/ decrease receiving speed volume and transmitting speed volume. The increase/ decrease of them is divided into five stages, that is, extremely small/small/ middle/large/extremely large. Extremely small is used in a case where a third person is not desired to hear calling contents so that transmitting speed volume is enlarged as a user speaks in small voice. Extremely large is used in a case where circumferential noise is extremely large. Thus, the control of the both volume is executed by one key operation. Besides, the key is commonly used for an operation only for receiving speed volume so that the user can easily understand.

Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method an electromagnetic pump allowing a sure and accurate selection of fixed resistors for setting the delivery rate from the pump within a prescribed range. SOLUTION: The electromagnetic pump is provided with a dummy resistor of design center for the electromagnetic pump, dummy resistors of small resistance and of larger one, and a switching means for selectively connecting one of the dummy resistors to the pump. The first measurement of the delivery rate is performed by carrying a driving pulse current through the pump via the dummy resistor of design center. If the rate falls within an allowable range in comparison with a reference flow rate, the same dummy resistor is put to use. If the rate is smaller or larger than that, the second measurement is performed by selecting a dummy resistor of smaller or larger resistance, respectively. Thus, selections are made from various fixed resistors by comparing the rate with the reference flow rate.  A finally selected fixed resistor is mounted on the pump, and a driving pulse current is carried through the pump to perform the third measurement of the delivery rate. This fixed resistor is employed if the rate falls within the range of the reference flow rate.
