Title: Sequence recording device
Inventor: AKASHI HIDETO
IPC: G05B23/02
Filed: 1982-06-23
Abstract: PURPOSE:To eliminate chattering, by comparing the state change of a signal existing before the present time point and stored in two memories storing temporarily information with that of a signal generated freshly. CONSTITUTION:When the signal name stored in a memory 402 is equal to the signal name supplied freshly through an input part 202, the signal information is temporarily stored in a memory 403 as long as the state of signal is off and set at ''0''. The signal information is disused if the state of signal is on and set at ''1'', and the contents of the memory 403 are turned into insignificant information. A timer 404 is initialized when the state of signal is on and off, respectively. While the timer 404 is priodically counted down. If the significant signal information is temporarily stored in the memory 403 when the count value of the timer 404 is set at 0, the signal information of the memory 403 is delivered to a central processor 203. Then the contents of the memory 403 are turned into insignificant information.

Title: Superconducting substance and production thereof
Inventor: UZUMAKI TAKUYA
IPC: C04B35/45
Filed: 1988-04-30
Abstract: PURPOSE:To provide a superconducting substance composed of Bi-Sr-Cd-Cu-O of a specific composition and having high stability and possibility to exhibit superconducting phase suitable for application. CONSTITUTION:The superconducting substance has a composition of BivSrwCdxCuyOz (1<=v, w, x, y<=3; 5<=z<=10). It can be produced by calcining a raw material mixture consisting of the oxides, carbonate compounds or nitrate compounds is Bi, Sr, Cd and Cu in an oxygen-containing oxidizing atmosphere at 700-1,100 deg.C. It is expected that superconducting phase does not develop in the above oxide superconducting substance having a composition out of the above range. When the calcination temperature is lower than 700 deg.C, the above starting raw material mixture cannot be calcined and sintered to the objective superconducting substance. Calcination at a temperature higher than 1,100 deg.C causes the melting of the raw material.

Title: Information recording and reproducing device
Inventor: SUZUKI KENICHI
IPC: G06K13/08
Filed: 1985-05-22
Abstract: PURPOSE:To execute quickly the acceleration and deceleration of a platen by accumulating the kinetic energy of the time when decelerating the placing base on which a recording medium is placed, and converting its accumulated energy to the kinetic energy of the platen, when accelerating the platen. CONSTITUTION:When a light shielding plate 35' shields a photocoupler 36', a motor is decelerated. The force for pressing a shuttle 11 in the left lower direction works so as to be roughly proportional to a contraction quantity of a spring 38', and by this force and the decelerating force of a motor 31, a moving speed in the right upper direction of the shuttle 11 is decelerated more quickly than the case when the spring 38' is not provided, and it stops in the end. This spring 38' is in a contracted state, the force for pushing back the shuttle 11 in the left lower direction works, and the shuttle 11 is moved and accelerated in the left lower direction. The motor 31 also accelerates the shuttle 11 in the same direction, and the shuttle is accelerated quickly by both the resiliency of the spring 38' and the torque of the motor 31. Even in case when the light shielding plate 35 shields a photocoupler 36, it is executed similarly.

Title: Semiconductor device having bump type electrode
Inventor: OOSHIGE KOUJI
IPC: H01L21/60
Filed: 1988-04-30
Abstract: PURPOSE:To prevent erosion, corrosion and so on of a pad electrode due to an atmosphere at the time of manufacture of a semiconductor device and at the time of a reliability evaluation test by a method wherein the edge parts of a metal layer on the pad electrode are covered with a second insulating film and the second insulating film having an aperture is provided at a region surrounded with these edge parts. CONSTITUTION:A second insulating film 15 is formed in such a way that it is extendedly provided on the edge parts of a metal layer 14 on a pad electrode 13 and these edge parts are covered with it and a bump electrode 16 is formed in an aperture 15b, which is formed at a region surrounded with these edge parts, of the film 15. For this, as the layer 14 is formed under the film 15, the evenness of the surface of the layer 14 is maintained sufficiently and no failure of the step coverage of the layer 14 is generated. Accordingly, when the aperture is formed on the film 15, for example, at the time of manufacture of a semiconductor device, the layer 14 functions as a passivation film to the base pad electrode 13. Thereby, an overetching is avoided and it can be prevented that the pad electrode is subjected to erosion or is corroded due to an oozing-in of an etching liquid.

Title: Liquid fuel combusting apparatus
Inventor: KITAJIMA SOUICHI
IPC: F23D11/34
Filed: 1978-09-04
Abstract: PURPOSE: To provide a liquid fuel combusting apparatus of the type in which combustion of fuel is caused after atomizing fuel with application of ultrasonic vibration to the same, wherein a region for dropping large-sized fuel particles is formed at a portion of fuel feeding passage located between a fuel atomizing section and a fuel combusting section, so that only small-sized fuel particles suited for combustion can be supplied to the burner head.  
     CONSTITUTION: When ultrasonic vibrator 1 is set into operation, vibration is transmitted through fuel oil 8. By the function of vibration transmitted in fuel oil 8, liquid column 9 is formed and fuel oil is atomized into particles 10, 11. Fuel oil thus atomized is carried into guide sleeve 12 by the air flow produced by fan 13 and finally reaches burner head 14. During the while when atomized fuel 11 drops downward through a large-particle settling section 18 having a relatively large sectional area and communicated at its top with outlet opening 16 of guide sleeve 12, fuel particles having relatively large sizes drop directly to the bottom by their own weight, so that only fine particles of fuel 10 are supplied to burner head 14 via fuel supply passage 19 and form flame 15. Fuel dropped to the bottom of section 18, on the other hand, is returned to fuel tank 3 via conduit 20.
