Title: Ultrasonic flaw detector
Inventor: AKATSU TOSHIAKI
IPC: G01N29/04
Filed: 1988-08-31
Abstract: PURPOSE:To perform measurement without two-dimensionally moving a flaw detector, to shorten a measuring time and to enhance measuring accuracy by mounting oblique angle opposed probes wherein transmitting vibrators and receiving vibrators are opposedly arranged at oblique angles to an ultrasonic flaw detector and arranging said oblique angle opposed probes on the circumference of a circle in a multipolar manner. CONSTITUTION:An ultrasonic flaw detector 1 is equipped with oblique angle opposed probes 2, 3 wherein transmitting vibrators 21-24 and receiving vibrators 31-34 are arranged opposedly at oblique angles. The ultrasonic waves obtained from said probes 2, 3 are displayed on a cathode ray tube as echos. The probes 2, 3 are subjected to multipolar arrangement (four poles of two diagonal axes of an X-axis and a Y-axis) of 21 and 31, 22 and 32, 23 and 33, and 24 and 34 on the circumference of a circle. When a nugget 8 is measured, the ultrasonic beam from a vibrator 2 propagates through an upper plate 6 and a part thereof transmits at the part of the nugget 8 to propagate to a lower plate 7. A part of the beam 9 is reflected from the lower surface of the upper plate 6 around the nugget 8 and the ultrasonic wave thereof is received by a vibrator 3.

Title: Double effect absorption refrigerating apparatus
Inventor: KUROSAWA MOKICHI
IPC: F25B15/00
Filed: 1989-08-22
Abstract: PURPOSE:To facilitate the mixing of a medium concentrated liquid and a concentrated liquid, make the startup of operation smooth and enhance the heat transmitting performance of a low temperature heat exchanger by switching the concentrated liquid from a high temperature regenerator between the front and rear positions of a medium concentrated liquid pump by means of pressure in the high temperature regenerator or a gas-liquid separator. CONSTITUTION:A concentrated liquid from a high temperature regenerator 1, after passage through a high temperature heat exchanger 4, is introduced into either a sucking pipe 22a of a medium concentrated liquid pump 6 or a discharge pipe 22b thereof via switchover valves 9 and 9' and this switching action is produced by a signal given the inner pressure of the inner pressure of the high temperature regenerator 1 or a gas-liquid separator 2. If, for example, this pressure is low, a concentrated liquid is led to the sucking pipe 22a so as to be mixed with a medium concentrated liquid and forced out by the medium concentrated liquid pump 6. If this pressure is sufficiently high, the concentrated liquid is led to the discharge pipe 22b so as to be mixed with the medium concentrated liquid and, due to the exertion thereon of the discharge pressure of the medium concentrated liquid pump 6, the flashing of the concentrated liquid can be prevented. This permits the flow rate of the mixed concentrated liquid in a low temperature heat exchanger 5 to be increased, the heat transmitting performance to be enhanced and the subject apparatus to be compacted.

Title: Thin film magnetic head
Inventor: KAKEHI AKIRA
IPC: G11B5/31
Filed: 1981-12-29
Abstract: PURPOSE:To increase the electromagnetic converting efficiency, by increasing the distance between the 1st and 2nd magnetic poles at a place near a recording/ reproducing gap compared with other parts. CONSTITUTION:An additional insulated layer is formed between an upper magnetic layer 3 and an insulated layer 6 so as to increase the distance between the layer 3 and a lower magnetic layer 2 of a yoke part 8 at a place near a recording/reproducing gap 4. As a result, the magnetic converting efficiency is improv ed. For instance, this example is compared with a case when the distance between the magnetic poles is fixed at the part 8. Thus the magnetic flux of the reading mode increases at a place near a coil 5. As a result, the intensity is increased for both of the magnetic flux and the magnetic field in the writing mode. This increases the efficiency of the electromagnetic conversion.

Abstract: PURPOSE:To attain high speed operation by combining two DC drive type Josephson FF circuits, giving each output signal as other input signal and giving it to each element so as to bring the Josephson element in order thereby setting a bias current. CONSTITUTION:A frequency divider is formed by connecting CS circuits CS1, CS2 in cascade. Asymmetrical two-junction magnetic quantum interference elements are used for the Josephson elements 71-74. Each element has three control lines 85, 86 and 87. Bias currents Ib1, Ib2 are given respectively to wires 78, 79, and an input current IN flows to a wire 77.
