Patent JP-S63241312-A (JP)
Title: Flow sensor
Inventor: TANAKA JUNICHI
IPC: G01F1/68
Filed: 1987-03-27
Abstract: PURPOSE:To reduce the temp. dependence characteristic of output, by forming the first photometric resistor detecting heat generating temp. and the second photometric restor for compensating temp. from the same material and further using a material low in resistance temp. coefficient in a heat generating resistor. CONSTITUTION:The output of a bridge is amplified by an operational amplifier 1 and a feedback is applied to a heater Rh to keep the temp. difference between the photometric resistor Rm for the heater and a photometric resistor Rt for compensating temp. constant. This temp. difference is set by a fixed resistor (r) but, when the temp. characteristics of the resistors Rm, Rt are equal, said temp. difference becomes constant regardless of the temp. of a fluid. As mentioned above, since the output itself of a flow sensor has no fluid temp. dependence essentially, the compensation for temp. becomes unnecessary.

Title: Ultrasonic horizontal vibration reed
Inventor: ISHIWATARI SHOICHI
IPC: B23B29/12
Filed: 1985-04-10
Abstract: PURPOSE:To efficiently convert a vertical vibration into a horizontal vibration, by forming an input part of uniform section, which engages an ultrasonic vertical vibration horn, in a thickness larger than that of an output part, having a tool, in the case of an ultrasonic horizontal vibration reed used for ultrasonic vibration cutting or the like. CONSTITUTION:A horizontal vibration reed 7 comprises an input part 5 and an output part 6. And a vertical vibration horn 1 is firmly mounted by a bolt 3 to the input part 5 in the vicinity of a horizontal vibration displacement loop.

In this way, a connection part with a vertical vibration horn 1, generating no heat, enables a vertical vibration to be efficiently converted into a horizontal vibration. As a result, the horizontal vibration reed 7 can render services to a field such as ultrasonic vibration cutting or welding removably connecting the vertical vibration horn and the horizontal vibration reed.

Title: Pulse receiver for searching fault point
Inventor: OKAMURA CHIYUUJI
IPC: G01R31/08
Filed: 1980-06-06
Abstract: PURPOSE:To facilitate searching of fault points in low resistance ground faults by providing a check pulse generating circuit within a pulse receiver, and if necessary, generating check pulses thereby permitting the operation checking of the receiver. CONSTITUTION:In the case of searching the fault point in a high voltage distribution line, an antenna 5 is put on the line, and the current flowing in the line is inductively detected. In case a fault point is a low resistance ground fault, virtually no current flows in the line past the fault point, and the detected current is equal to zero, and therefore is cannot be discriminated from the fault of a detector. Thereupon, in such a case, the antenna 5 is spaced from the distribution line, and a signal changeover circuit 12 is changed over to selectively connect a receiving gate circuit 15 and a check pulse generating circuit 13. Check pulses are generated by operating a switch 14 for checking and whether the indication of a detecting meter 17 is a predetermined value or not is checked.

Title: Generator
Inventor: SHIMIZU MOTOHISA
IPC: H02J3/42
Filed: 1992-02-27
Abstract: PURPOSE:To permit the continuation of parallel operation stably without employing any special adaptor and the like or without necessitating any special means. CONSTITUTION:Upon parallel operation, the rectangular conversion of the detecting waveforms of an output voltage and an output current is effected with respect to the reference of respective zero-cross points. The width of a phase difference between the voltage phase of detecting waveforms, converted through the rectangular conversion, and the current phase of the same or the amount of advanced phase or delayed phase is detected by an XOR 81 while the judgement of advance phase or delay phase with respect to the voltage of the current is effected by an XOR 85. The decision of these phases is effected in every half cycle of the waveform, and therefore, the phase difference can be detected as a substantially linear characteristic within the whole range of -180 deg.C to +180 deg.C. Further, the increase and decrease of a frequency are effected in accordance with a detected pulse width by an oscillating unit whereby the phase difference between the output voltages of both generators can be reduced.

Title: Lead frame and semiconductor device to use lead frame thereof
Inventor: ENOMOTO USUKE
IPC: H01L23/495
Filed: 1985-04-12
Abstract: PURPOSE:To improve the bondability of a lead frame by a method wherein a metal such as copper is plated on the main surface of the lead frame, a smooth first metal film is formed on the surface of the lead frame material and a second alloy film with a higher hardness, such as a nickel-phosphorus alloy film, is formed thereon according to an electroplating. CONSTITUTION:A lead frame L itself is formed of a nickel 42 alloy 50 and a copper layer 51 is formed on the upper surface thereof according to an electroplating. This is because a plating is hard to be performed on the nickel 42 alloy 50. Furthermore, a nickel layer 52 is formed on the surface thereof according to an electroplating. It is necessary to form at least a plating film on the region to be used for bonding. The surface treatment can be performed at low cost as being a plating treatment. There is a difference between the hardness of copper and that of nickel or a nickel alloy. This difference further improves the bondability of the lead frame.
