IPC: H01L21/48
Filed: 1986-05-09
Abstract: PURPOSE:To enable correcting a curved IC terminal to a regular posture according to the number of its insertion and removal and to realize the automatic operation of IC mounting by mechanizing the operation of correction by inserting and removing the IC terminal with a jig by appropriately shifting the position of the IC. CONSTITUTION:At first, a hole 2 at the upper left corner of a jig main body 1 is adjusted to an IC terminal and the IC terminal is once inserted in the hole 2 of the jig main body 1 and is removed and the center of the terminal is within a circle A. Next, if the second inserting and removing are carried out by shifting the IC to the direction by one row, the center of the terminal is between points M, N (shown by a full line) in the circumference of a circle B interposed between the two tangents to the circle A from the center of the circle B. Then, the IC is turned 90 deg. to the left to adjust the lower left corner of the jig main body 1 to the terminal and the third inserting and removing are carried out. By increasing the number of inserting and removing in this way, the center of the IC terminal can be infinitely brought accurately to a reference point 5c.

IPC: G09B3/04
Filed: 1988-04-28
Abstract: PURPOSE:To realize learning corresponding to a real test by arranging an explanatory section and a problem section in parallel, and solving a problem text in the problem section as referring to key words or explanatory display, etc., arranged in both sections. CONSTITUTION:A learner hides the explanatory section 1 with a hide plate A, and reads the problem texts 30 and 60 in the problem sections 2 and 4, and fills problem null columns 30 and 60, and when no problem null columns 2 and 4 cannot be filled, a head text 10 at the beginning part of the explanatory section 1 can be displayed by sliding the hide plate A. Since the head text 10 includes the key word, it is possible to obtain a hint only by reading the head text 10, and to fill the problem null columns 30 and 60 if the learner can remember storage. When the learner cannot remember, a predict mark appears by sliding the hide plate A, and since a code attached on the predict mark coincides with the codes attached on the problem null columns 30 and 60, the storage of the head text 10 corresponding to the code becomes an advantageous hint. When still it is not impossible to remember the storage, the explanatory display that are answers corresponding to the problem null columns 30 and 60 are displayed by sliding the hide plate A. In such a way, it is possible to obtain a large learning effect.

Abstract: PURPOSE:To obtain a magnetic disc free from surface defects, superior in etching resistance, and high in reliability, by forming a thin nonmagnetic iron oxide film on an aluminum or its alloy base, and on this film a thin ferromagnetic iron oxide film. CONSTITUTION:The thin nonmagnetic film 3 of alpha-Fe2O3 is formed on a base plate 4 made of aluminum or alloy consisting mainly of it in the presence of gaseous argon contg. a prescribed amt. of O2 in a reduced pressure by the high frequency wave sputtering method, and a Fe3O4 layer is formed on the layer 3 by the sputtering method, and then, it is oxidized under heating at 300 deg.C to convert it into a ferromagnetic iron oxide layer 2 of gamma-Fe2O3. Otherwise, the film 3 is reduced in a gaseous H2 stream to form an Fe3O4 layer down to a prescribed depth from the surface, and it is oxidized under heating to give gamma- Fe2O3 and the layer 2 is formed on this layer 3 converted.

Title: Transmitting/receiving circuit
Inventor: TAKEUCHI YASUTO
IPC: G01S7/52
Filed: 1987-04-30
Abstract: PURPOSE:To achieve simplification, by using a preamplifier transistor with a base grounded to apply a transmitting high voltage signal to a collector-base junction high in the voltage withstand with the inversion of a collector and an emitter. CONSTITUTION:A transmitting waveform generation circuit 1 is excited by a clock to generate a high frequency pulse signal, which is applied between the base and emitter of a pulser Tr (transistor) 3 through a transformer 2. The collector of the Tr 3 is connected to the emitter of a preamplifier Tr 6. A reverse bias is applied to the collector of the Tr 6 while the emitter thereof is reversely biased and, hence, the Tr 6 is cut of by a transmitting high voltage signal to keep any transmitting signal from entering the subsequent receiver. This protects the Tr 6 inverted from dielectric breakdown even when receiving a relatively high voltage at the emitter thereof in operation. A high frequency pulse is transmitted through a coupling capacitor C2, a cable 4 and a vibrator element 5. A signal received with the element 5 is inputted into the Tr 6.
