Title: Detecting method of deteriorated part of porcelain tube
Inventor: ENOKIDO KIYOMASA
IPC: G01N29/04
Filed: 1991-06-28
Abstract: PURPOSE:To enable detection of a defective part through comparison of the part with a sound part without destructing a porcelain tube, by bringing a probe into contact with the surface of porcelain and by observing a change in the echo of an ultrasonic wave. CONSTITUTION:When a probe 5 is set at a setting position 1, an utrasonic wave beam 6 is reflected at the bases B1 and B2 of folds of a porcelain tube 3 and echoes can be observed. When there is a defective part 4 (a degenerated part due to an alkali component of cement 2) in the route of the beam 6, however, the beam 6 is attenuated and the echoes can not be observed. Next, when the probe 5 is set at a setting position 2, the beam 6 is reflected at B. When the defective part 4 exists, however, the echo can not be observed or it is weak. When the probe 5 is set at setting positions 3 and 4, moreover, the beam 6 is reflected at B respectively and the echoes can be observed. As stated above, the magnitude of the echo changes in a large degree according to whether a defect exists in the material of the porcelain tube 3 or not, and therefore the defective part can be discriminated and detected with ease.

Abstract: PURPOSE:To obtain a piezoelectric transformer DC/DC converter having excellent output stability by providing a frequency conversion feedback circuit for comparing a voltage converted from a mechanical vibration with a reference voltage, converting their difference voltage to a frequency signal, and supplying it to a driving circuit. CONSTITUTION:When a power is supplied from an input power source 1 to a driving circuit 2, the circuit 2 drives a piezoelectric transformer 3, which outputs a voltage to a rectifying and smoothing circuit 4, and the circuit 4 supplies its output to a load 5. A comparator 7 compares the output voltage from the circuit 4 with a reference voltage 6, and outputs their differential voltage to a V/F converter 8. The differential voltage from the comparator 7 is converted to a frequency by a V/F converter 8, and supplied to the circuit 2. The circuit 2 controls the driving frequency of the transformer 3 based on the frequency signal from the converter 8 to regulate the output voltage of the circuit 4. Thus, an output stability is improved.

Title: Latch circuit
Inventor: HASHISHITA RYUICHI
IPC: H03K3/356
Filed: 1992-06-18
Abstract: PURPOSE:To prevent Punch-through of data by inputting an input signal to a MOS transistor (TR) closer to an output terminal of a 1st stage clocked inverter and inputting a clock signal to a MOS TR closer to a power supply terminal. CONSTITUTION:A clock signal phi is inputted to a gate of a PMOS TR P4 and a clock signal inverse of phi is inputted to a gate of an NMOS TR N4. An output signal OUT is extracted from a common drain of the TRs P4, N4. A change in an output V3 of the 1st stage clocked inverter is slow as shown in (f) in figure (b) because a source-drain capacitance of the NMOS TR N2 is required to be discharged. Then the on-time t3 of the PMOS TR P3 is slow and the degree of rising a potential of the output signal OUT is reduced as shown in (6) in the figure (b). Thus, malfunction is surely prevented.

Title: Mobile radio equipment
Inventor: HABUKA RIYUUJI
IPC: H04B17/23
Filed: 1983-09-01
Abstract: PURPOSE:To attain communication service suitable for the operating mode in response thereto by forecasting the transition of a reception voltage level at a point of time and thereafter from a displayed reception voltage level and a differentiation output. CONSTITUTION:Peak points of time A1, A2 and a notch point of time B1 are repeated alternately in a reception wave because it is subject to fading. The gradient of a curve representing the timewise transition of a reception output level 3 at a time region T1 at the midpoint between the points of time A1 and B1 is negative and that at a time region T2 between points of time B1 and A2 is positive. Thus, the change in the level 3 is forecast by discriminating whether a sign of the differentiation output 5 of the level 3 is positive or negative. Then a reception level state discriminating circuit 8 to which the level 3 and the output 5 of a differentiation circuit 4 are inputted discriminates the radio wave reception state at present and also displays the sign of the level 3 and the output 5.

Abstract: PURPOSE:To secure such a displacement controlling mechanism that is high in reliability, by forming a seal groove in both inner and outer circumferential surfaces of a control member, in the case of the displacement controlling mechanism that rotates the control member according to differential pressure between two chambers capable of varying each pressure and varies an opening angle of a bypass port. CONSTITUTION:Each pressure receiving member 26 is being housed in two sector-form pressure operating chambers 27 formed in a rear side block 9, and a control member 24, which controls the pressure receiving member 26 and an opening angle of the bypass port connected to this member 26 by differential pressure between a first chamber 271 and a second chamber 272 partitioned off by the pressure receiving member 26, is constituted so as to be moved. Since a seal member 31 is installed in fitting grooves 33 and 34 on both inner and outer circumferential parts of the control member 24, width of the pressure receiving member 26 is widened up to its full extent of the control member 24 so that a pressure receiving area of the member 26 is increasable. With this constitution, driving torque of the control member 24 is increased, and hystereis is restrained, thus controllability is improvable.

Filed: 1989-06-22
Abstract: PURPOSE:To efficiently pickle an annealed band stainless steel at the time of continuously pickling the steel by electrolytic pickling by providing a diffuse dialyzing membrane between the steel and an electrode. CONSTITUTION:An annealed band stainless steel 1 having an oxide scale on its surface is passed through the first pickling tank 2 and second pickling tank 3 contg. an aq. Na2SO4 soln. as the aq. neutral salt soln. Many anodes and cathodes 5 are provided in the passage, and the steel is electrolytically pickled. In this case, the diffuse dialyzing membrane 9 is provided between the steel 1 and the electrode 5, and the metal ion is attracted by the electrode 5 and passed through the membrane 9. Conversely, the metal ion tends to move toward the steel in the process where the steel 1 causes electrodeposition, but the intrusion of the metal ion in the vicinity of the steel is prevented by the membrane 9. Consequently, the steel is pickled with the pickling soln. having a low content of metal ion, the descaling property is improved, and the soln. is effectively utilized after pickling.
