Title: Ultrasonic flaw detection method
Inventor: SHIRAI TASUKU
IPC: G01N29/44
Filed: 1994-01-12
Abstract: PURPOSE:To provide an ultrasonic flaw detection method for detecting flaw at a welded part of a piping made of an austenite based stainless steel casting material in which discrimination can be made easily between a detect echo and a pseudo ecno. CONSTITUTION:Flaw is detected using a 36 deg. longitudinal wave of 1MHz and a detect echo is discriminated from a pseudo echo by noticing the difference of frequency distribution in the original flaw signal (RF signal) of an echo being detected. If a first peak is located on the lower frequency side than a second peak, a decision is made that the detected echo is a pseudo echo. It the first peak is located on the higher frequency side than the second peak, a decision is made that the detected echo is a defect echo in the case where the line lower by 6 dB than the second peak has two intersections. If the line has more than two intersections, a decision is made that the detected echo is a pseudo echo.

Title: Oscillator having digital temperature compensating circuit
Inventor: ARUFUONSU ZUMUSUTETSUGU
IPC: H03L1/02
Filed: 1981-01-09
Abstract: The oscillator circuit comprises a digital temperature compensation circuit connected to a low and a high frequency quartz oscillator. The two quartz oscillators have the same inversion temperature points and a different temperature behaviour. In the temperature compensation circuit a beat frequency is produced between the divided signal of the high frequency oscillator and the frequency of the low frequency oscillator and then fed to a correction circuit and multiplied therein with a correction factor which has been stored in a PROM. The obtained correction signal is fed into the frequency divider chain for obtaining a temperature compensated outgoing signal for use in a timer circuit. The temperature compensation circuit is simply designed and allows high accuracy, which is particularly well suited for a wristwatch or a photo camera.

Title: Straightening flow device for plant piping
Inventor: UMEMURA KAZUO
IPC: F17D1/08
Filed: 1978-01-13
Abstract: PURPOSE: To prevent erosion in the inner bulkhead of piping by stably straightening two phase flow in such a way that a straightening plate or a straightening vane is provided in the inner bulkhead of the piping in order to straighten the flow so that fluidic membrane can involve fluid which has factors to always erode the inner bulkhead of the piping.  
     CONSTITUTION: A straightening vane 8 in bursting-star pattern is installed in the inner bulkhead of a plant piping 7 to pass two fluid, such as particle containing steam and water. This facilitates to constantly straighten mist flow containing fluidic membrane and particle of two phase flow passing through the inside of the piping 7 with use of the straightening vane 8. In other words, fluidic membrane flows through the side of inner bulkhead of the piping, and mist flow which is involved in the fluidic membrane results in flowing. Consequently, when two phase flow of the fluidic membrane flow passes through a bent piping part or obstacles in the piping, centrifugal force in the fluidic membrane flow reduces for balancing with surface tension of fluidic membrane and stabilizing fluidic membrane flow. Thus, since the inner bulkhead of the piping is covered by fluidic membrane flow in any part, it eliminates erosion by particle in the mist flow.

Filed: 1985-01-11
Abstract: PURPOSE:To decrease the capacity between the gate and the source of an MOSFET and the capacity between the gate and the drain without effects on gm, by providing a low concentration layer having the same conducting type as that of an active layer between the active layer and a gate electrode. CONSTITUTION:On a semi-insulating GaAs substrate 1, an active layer 2 is formed by a selective ion implantation method. A low concentration layer 3 having the same conducting type as that of the active layer is grown on the layer 2 by a VPE method and the like. Then high concentration layers 4 and 5, which penetrate the low concentration layer, are formed by a selective ion implantation method at parts, where source and drain regions are formed. The unnecessary part of the low concentration layer is etched. Then a gate electrode 6, a source electrode 8 and a drain electrode 9 are formed. In order to form a depletion region in the low concentration layer 3, a slight voltage (less than 0.1V) is enough. Therefore almost no effect is applied to various characteristics of the FET such as mutual conductance gm and a pinch OFF voltage VP. The gate-source capacity Cgs and the gate-drain capacity Cgol can be decreased by the thickness of the low concentration layer 3.
