Title: Liquid hole plug for storage battery
Inventor: NAKAJIMA TAKASHI
IPC: H01M2/12
Filed: 1983-09-05
Abstract: PURPOSE:To prevent direct shock to a liquid hole plug caused by vibration and prevent generation of an electrolyte film which blocks a circulation hole and increase overflow resistance by improving a shape of a circulation hole of a liquid hole plug. CONSTITUTION:Circulation holes 4 are bored in the lower surrounding wall of a screw 3 which is used to fix a liquid hole plug comprising thermoplastics to a storage battery cover. Each one fourth of right and left surrounding length of an opening which forms the circulation hole is formed as a thin edge. Concave grooves 6 are formed in the surrounding wall 5 of the plug 1 in a lateral direction from the portion containing the thin edge of the circulation hole 4. Liquid which flys up by vibration of a battery strikes to the lower part of the plug 1, a splash preventing plate 7, and drops through the circulation hole 4. Althrough a part of liquid tends to form a liquid film which blocks the circulation hole, since liquid in the concave groove 6 has large surface tention, the liquid film is instantaneously brocken and venting action is not hindered.

The nitride film 17 is formed over the surface of the substrate 1, and masks of photosensitive resin films 13 are selectively formed. Using a parallel flat reactive sputtering device, reactive sputter etching is performed under a partial pressure ratio of the introduction gas CF4:H2 at 1:4. The regions of an emitter window 10 and a base contact window 11 are opened. An electrode metallic layer is evaporated from vertically above and further formed into electrode patterns 14 and 15 by the photoetching technique.

Title: Solar power generation device
Inventor: FUJIWARA TERUIE
IPC: H01J40/16
Filed: 1982-09-20
Abstract: PURPOSE:To obtain a solar power generation device which converts photo-energy into electric energy directly by converting the photo-energy and the thermo- energy and the thermo-energy of sunlight into photo-electrons and thermions. CONSTITUTION:Sunlight (S), after being focused on a practical focus (P) through convex lens (B) or reflecting plates (C) and (C'), is diffused within a device body (A) in vacuum before being discharged into a heat-recovering electric discharge body 15 from its opening 16. When the sunlight (S) bumps against a film 13 formed on the inner surface of the body 15, electrons of the film 13 irradiated by light are discharged outside the body 15 from the opening 16 as photo-electrons (A) before they are attracted by a metallic film 8 thereby producing photoelectric current. On the other hand, when the body 15 is heated by solar energy, thermions (b) are discharged from a film 14 (cathode) formed on the outer surface before being attracted by metallic films 8 and 9 thereby producing thermoelectric current. In addition, infrared rays (R) produced owing to the temperature rise caused by heating of the body 15 are repeatedly reflected from the mirror surfaces of the metallic films 8 and 9 to heat the body 15 acceleratingly and accelerate generation of thermions, thereby producing a large amount of current by increasing the voltage difference between the body 15 and the metallic films 8 and 9.

Title: Deenergization operated type electromagnetic brake
Inventor: YASUDA TATSUMI
IPC: F16D65/18
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To prevent the separation of a plating layer caused by being used for many years by applying strong impulsive force, by providing a braking spring by which a magnetic stainless steel-made armature is pushed and pressed to a brake disc. SOLUTION: When a deenergization condition is set, an armature 8 ms abutted on an inner disc 11 by spring force, and a projection 8a is brought into contact with the wall surface of an engaging groove 9c. However, magnetic pole plates 4, 5 and the armature 8 are manufactured by magnetic stainless steel, therefore the separation of a plating layer due to impulsive force may not cause, and also sliding between the projection 8a and the wall surface of the engaging groove 9c may not be deteriorated by rust, and further a pressure receiving member 9 is also made of stainless steel, thus the smooth action of the armature 8 can be retained in a satisfactory condition for many years.  Also, when an energization condition is set, the armature 8 is magnetically attracted to the magnetic pole plates 4, 5 against the spring force, damps impulsive force applied to a field core 1, and prevents the separation of the plating layer.

Filed: 1979-12-17
Abstract: PURPOSE: To eliminate an excessive sound volume given through an earphone, by providing an electronic switch which performs a mode switching between record and reproduction of a miniature tape recorder and providing a monitor circuit on said recorder which can control the sound volume in either mode of record and reproduction.  
     CONSTITUTION: In the recording action, the first signal among the voice signals sent from the mike 11 is supplied to the ALC circuit 13 and then controlled automatically to the record level. The second signal is recorded by the magnetic head 17 through the equalizer circuit 15. The third signal is delivered to the monitor jack 24 from the electronic switch part 19 via the variable resistance 21. The control transistor 26 is turned off, and the speaker 31 does not work. In the reproducing action, the switch part 19 is reversed and the transistor 26 is turned on. Thus the speaker works. In this instant, an earphone is inserted into the monitor jack, and thus the discharge of sound given through the speaker is stopped like the recording mode.

Filed: 1986-07-14
Abstract: PURPOSE:To carry out a working test of a data recording/reproducing device by storing temporarily loopback test data in a deinterleave memory of a decoding circuit and then reading out the test data after the input of data is ended. CONSTITUTION:The test data inputted from a host processor via a bidirectional bus 10 is inputted to a demodulation circuit 5 via a coding circuit 2 and a modulation circuit 3 after bypassing a high-density recorder 4 through a loopback switching circuit 7. The data demodulated by the circuit 5 is stored temporarily in a deinterleave memory 8 of a decoding circuit 6. When a controller 1 detects the end of the test data, the controller 1 reads the stored data out of the memory 8 to perform other processes and transfers the data to a host processor via the 10 to verify it. As a result, the test data of both directions never exist at a time on the bus 10.

Abstract: PURPOSE:To detect early a change of a plant data at its sign stage by using a residual signal between a dynamic characteristic model with which the steady variation can be described and the measured value and giving the statistic process to the residual signal. CONSTITUTION:For diagnosis of a small-scale breakage phenomenon (small LOCA) within a container, the atomic power water level, the pressure of a reactor, the container pressure, etc. are used as the data on an atomic power plant 1 which have variations due to the generations of the small LOCA.

Then DC components P10, P20,...,Pn0 of each data are removed, and variation components x1, x2,...,xn of each plant data are delivered. Variation detectos 31, 32,...,3n use a dynamic characteristic model 9 to estimate the variation of each plant data every sampling cycle and decides the presence or absence of variation of a steady state from the statistic quantity of an estimated residual between the measured value and the estimated value.

Abstract: PURPOSE:To explosively splash about fountain water with the bubbles going into pieces near the top of the water column by providing a nozzle with an air inlet opening which allows the air to accompany the water flow under the negative pressure caused by the inner stream of water in the nozzle in such a manner as to face the water surface of a water tank. CONSTITUTION:A column of water is formed by spouting water from a nozzle 9 placed in a water tank 1 through the inner space of a cylindrical member 3 mounted on the water tank 1 and the water being spouted from the nozzle 9 is circulated back into the water tank 1. The nozzle 9 is provided with an air opening 10 which allows the air to accompany the water flow under negative pressures caused by an inner stream of water in the nozzle and which faces the water surface W of the water tank 1. The space between the inner surface of the cylindrical member 3 and the aforesaid water column is so dimensioned as to allow the water attached to the inner surface of the cylindrical member 3 upon splashing around near the top of the water column to drop therefrom in a film form. This results in splashing the water violently all around near the top of water column being spouted, as if exploding, thus affording a power ful scene of the fountain to viewers.
