Title: Regulating method of reference voltage value in ultrasonic flow velocity measurement
Inventor: TOMITA AKIO
IPC: G01F1/66
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To measure the precise timing of a received wave to perform a highly precise ultrasonic flow velocity measurement by determining the maximum voltage value of the positive or negative polarity wave of the received wave used for receiving wave arrival timing. SOLUTION: A comparator 7 compares the output value or received wave from an amplifier circuit 5 with a reference voltage from a reference voltage generating circuit 6 and transmits a comparator signal. In a reference voltage regulating part 14, the maximum voltage value A of positive or negative polarity wave of the received wave used for receiving wave arrival timing is determined according the expression A=E/sinθ, and the reference voltage value is set to the middle between this maximum voltage value A and the maximum voltage value A of the positive or negative polarity wave of this side. In the expression, E represents the reference voltage value before regulation, and sinθ represents the sine value when the polarity wave reaches the reference voltage value before regulation E.  According to this, even if the amplitude of the received wave is changed by a change of the temperature or flow velocity of a fluid, the same polarity wave can be detected, and the precise arrival timing of the received wave can be measured.

Title: Semiconductor integrated circuit device
Inventor: SASAKI MUTSUMI
IPC: H01L21/822
Filed: 1994-04-26
Abstract: PURPOSE:To simplify the circuit design and to lighten stress concentration and electric field concentration at the corners of a pad and a wiring by connecting, to a pad having at least one linear side, a wiring having a longitudinal side forming a straight line with this linear side. CONSTITUTION:A wiring has a side 2a forming a straight line with a linear side 1a of a pad 1. Since the one side 1a of the pad 1 and the one side of the wiring are on one straight line, the number of corner parts 3 becomes smaller than before, and time required for circuit design can be shortened. Besides, product reliability can be raised since it becomes possible to lessen the number of spots of cracks of protective films generated by stress concentration, and breakdowns of interlayer insulating films caused by electric field concentration, i.e., the number of corners. Incidentally, it does not matter if the wiring 2 is formed so as to form a straight line with each of the opposed two sides of the pad 1. On this case, it is possible reduce further the number of spots of the cracks of the protective films generated by stress concentration and the breakdowns of interlayer insulating films by electric field concentration (i.e., the number of corners). Besides, it is possible to shorten time required for the circuit design further.

Title: Sending system of calling station name talkie
Inventor: KUBO MASAHIDE
IPC: H04Q3/54
Filed: 1979-07-13
Abstract: PURPOSE:To ensure the sending of the calling station name talkie tone to the small- capacity switchboard without impairing the economical property, by sending the calling station name taklie to the operator only for the period during which the incoming trunk closes the message channel and then receives the connection end signal. CONSTITUTION:The incoming trunk confirms the closure of message channel NW with the operation of relay A by the start given from the preceding station to inform this closure to CCT (common control unit) as well as operate relay B. And CCT actuates relay S when it decides that the connection is possible to the attendant board. With operation of relay S, busy tone RBT is induced to the winding of relay A to be sent to the originating subscriber. With the answer of the operator, relay L operates to give the originating station name talkie tone to the operator through talkie device TKE. Knowing the NW closure, CCT secures a certain timing to give the release to relay LA via relay T and then stop the sending of the tone sent from RBT and TKE each. In case the sending of the calling station name talkie is not required, relay T is operated immediately to stop RBT. Thus the talking becomes possible between the subscriber and the operator.
