Patent JP-S61139973-A (JP)
Title: Cassette loading device
Inventor: NISHIDA IKUO
IPC: G11B15/675
Filed: 1984-12-11
Abstract: PURPOSE:To prevent securely a cassette from being inserted into a cassette holder improperly and loaded improperly by providing a projection for wrong insertion prevention to the lower plate of the cassette holder, and also providing a claw for wrong insertion prevention. CONSTITUTION:When the cassette 4 is inserted into the cassette holder 32 in the normal state, the gap D between the claw 54 for wrong insertion prevention and the lower plate 32a of the holder 32 is a little bit larger than the thickness T of the cassette 4, so the cassette 4 is inserted up to the end part of the holder 32 without colliding against them. When, however, the cassette 4 is inserted in the opposite front-rear direction or while turned over, the front edge part of the cassette collides against the projection 10 for wrong insertion prevention to prevent the wrong insertion and the wrong loading. In this case, even when the cassette 4 is pressed forcibly so as to go beyond the projection 10, the upper edge part of the cassette 4 collides against the prevention claw 53 to prevent the wrong insertion.

Title: Method for deodorizing dehydrated cake
Inventor: TAKANO MITSUO
IPC: C02F11/06
Filed: 1985-11-21
Abstract: PURPOSE:To prevent the generation of a malodor coming from the surface of a dehydrated cake, by scattering a solid compound generating active oxygen to the surface of the dehydrated cake. CONSTITUTION:Sewage and org. Substance-containing industrial waste water are biologically treated and dehydrated to obtain a dehydrated cake with water content of about 75%. A solid compound generating active oxygen such as calcium peroxide or magnesium peroxide is scattered to the surface of the dehydrated cake. Active oxygen oxidizes a malodorous component such as hydrogen sulfide generated from the dehydrated cake and markedly prohibits the activity of anaerobic bacteria causing a malodor and suppresses the formation of sulfide. By this method, the deodorizing of the dehydrated cake and the regeneration of the malodor can be prevented.

Title: Video tape recorder
Inventor: NAGOYA TETSUO
IPC: H04N5/92
Filed: 1984-12-10
Abstract: PURPOSE:To improve S/N in any reproducing mode by forming the 1st and 2nd detecting means reversing the relation of crosstalk suppressing capacity in accordance with the shifted distance of tracks and selecting a digital video signal in accordance with the shifted distance of the tracks. CONSTITUTION:A digital video signal picked up from a magnetic tape by a rotary head 31 is amplified by a pre-amplifier 32 and then applied to the 1st digital video signal detecting part 33 adopting an integration detecting system and the 2nd digital video signal detecting part 34 adopting an amplitude detecting system. When the shifted distance of the tracks is small in a normal reproducing mode, the detected output of the integration detecting system of which crosstalk suppressing capacitity is high is selected and led into terminals 39, 40. When the shifted distance of the tracks is large in a variable speed reproducing mode, the detected output of the amplitude detecting system of which crosstalk suppressing capacity is higher than that of the integration detecting system is selected and led into the terminals 39, 40.

Title: Remote-controlled power source connection device
Inventor: NOGUCHI YOSHIHIRO
IPC: H01R13/633
Filed: 1987-10-15
Abstract: PURPOSE:To make it possible to easily pull a plug by a remote control operation from an electric appliance side by making the tip of a projection bar to be detachable. CONSTITUTION:While making it possible to release a plug 3 from an outlet by closing a switch 12 and thereby projecting a projection bar 32 incorporated in the plug 3, the tip of the projection bar 32 is made detachable. Namely, as the plug can be pulled out of the outlet by turning the switch 12 on thereby projecting the projection bar 32 out of the plug 3 body, unlike heretofore it is not necessary to go to the place where an electric appliance is placed at the outlet. Also, since the tip of the projection bar is made detachable, even if a condition occurs in which the projection bar 32 cannot be engage-stopped in the plug 3 body by any case, the plug can be used as an ordinary plug by removing the tip of the projection bar 32.
Patent JP-H02106051-A (JP)
Title: Electronic analysis method
Inventor: MATSUSE KIMIHIRO
IPC: H01L21/66
Filed: 1988-10-14
Abstract: PURPOSE:To enable exact analysis without changing the analysis object state of an object to be analyzed by a method wherein, after the surface of the object to be analyzed is coated with a film constituted of atom lighter than metal atom, a corpuscular beam is projected, and analyzing is performed by detecting the secondary electron emitted from the object to be analyzed. CONSTITUTION:At the time of analyzing an alumina film 14, a film constituted of atom lighter than metal atom, e.g., an amorphous silicon film 15, is stuck on the alumina film 14. Electron beam 1 from an electron gun 2 is converged by a convergent lens 3, and deflected in a specified direction by a deflection electrode 4. The deflected electron beam 1 is converged by an objective lens 6, and made to irradiate on the surface of a wafer 7. Then secondary electron 9 is emitted from the amorphous silicon film 15, the alumina film 14 and an Al film 13. The secondary electron 9 is detected by a secondary electron detector 10; the output signal from the detector 10 is amplified by an amplifier 11; film quality is analyzed based on the kinetic energy detected by a control unit 12. Thereby, exact analysis is enabled without changing the analysis object state of an object to be analyzed.

If the frame 2 is intentionally about to be turned in A direction in a state where it is stored, the 2b part of the frame 2 becomes engaged with the 1b part of the frame 1, and if the frame 2 is intentionally about to be turned in B direction, the cover member 4a braces itself between frames 1, braking itself. On the other hand, when the device is used, the projecting part 4a of the cover member 4 provided on the frame 2 is removed from the recessed part 1a of the frame 1, and the frame 1 is bent in A direction centered around the fulcrum 3 for use.

Abstract: PURPOSE:To improve the reliability by housing a printing part into a second enclosure different from a first enclosure which houses an input part, a processing part and a display part and also providing a modem means which can communicate without a physical contact in 2 enclosure and exchanging data. CONSTITUTION:The time of an input and editing, namely, the time for operating a keyboard 102 while looking at display part 103 is much longer than the time when a printer 106 and a floppy disk drive 211 are operated. When a RAM 203 has the capacity exceeding some degree, document data whose use frequency is high can be reserved in a main body and it may be suffice printing is executed once after the document generation is ended. Therefore, a printer part 106 is put into the enclosure different from an enclosure 101 which houses an input part 102, a processing part and a display part 103 and the mutual connection is executed without physical and electric contacts by using light, magnetic ultrasonic waves, etc. Thus, the portability is improved and by using a non- contact communicating means, the reliability can be improved.
