Inventor: KITAGAWA SHIGERU
IPC: G01N29/12
Filed: 1991-03-12
Abstract: PURPOSE:To enable an abnormal adhesion of a metal plate with a compact and portable device by exciting the metal plate by the use of electromagnetic force, detecting a supersonic wave which is generated by vibration of the metal plate, and detecting abnormal adhesion of an adhesive which is included between the metal plate and other member surface without any contact. CONSTITUTION:A hollow electromagnetic coil 7 and a magnet 12, as needed, are provided on a surface of a metal plate 3, AC current is allowed to flow to this electromagnetic coil 7 intermittently, and eddy current is generated on a surface of the metal plate 3 by a magnetic field which is generated by the AC current. A vibration force is generated at the metal plate 3 due to interaction between a magnetic field due to the magnet 12 which is placed along with the eddy current and a magnetic field which is generated by superposing DC current to the electromagnetic coil 7. A sound wave which is generated by vibration which is propagated through the hollow electromagnetic coil 7 is absorbed by a sound resonator concentrating device 9 which is installed at the rear part of a coil and then vibration status of the metal plate 3 is detected, thus enabling the adhesion status to be discriminated.

Title: Production of active matrix substrate
Inventor: TANAKA SAKAE
IPC: H01L27/12
Filed: 1988-03-28
Abstract: PURPOSE:To prevent the deterioration of image quality by forming a silicon oxide layer on an ITO layer at the same pattern as the pattern of the ITO layer so that the ITO layer is prevented from being reduced even if a silicon nitride layer is used as a protective film. CONSTITUTION:The ITO layer 6 is formed by a vacuum vapor deposition method and further, the silicon oxide layer 7 is formed by a plasma CVD method. A photoresist 12 is coated on the silicon oxide layer 7 and is developed to the shapes of source electrodes 8, drain electrodes 9, picture element electrodes 10 and source wirings 11. The silicon oxide layer is then etched with the photoresist 12 as a mask by a soln. of hydrofluoric acid: ammonium fluoride=1:6 and in succession, the ITO layer 6 is etched by a ferric chloride soln. Since the silicon oxide layer 7 is formed at the same pattern as the pattern of the ITO layer 6 on the ITO layer 6, the exposure of the ITO layer 6 to a reducing gaseous atmosphere of ammonia, etc., is obviated at the time of forming the silicon nitride layer 13. The high-quality image is thereby obtd.

Title: Suction type pneumatic transport method and device for granule
Inventor: TERADA SATOYUKI
IPC: B65G53/24
Filed: 1990-03-23
Abstract: PURPOSE:To enable transport at a low speed and to prevent damage on granules by supplying a small amount of air having its speed less than the floating speed of the granules in a transport pipe in the middle of the pipe, and by repeatedly switching an sucked air capacity between the air capacity corresponding to a speed less than the floating speed and the air capacity corresponding to a speed more than that for a thieving columnar transport. CONSTITUTION:First, a flow regulating valve 40 is almost opened, and the air capacity flowing in a transport pipe 10 is set extremely smaller than that corresponding to the floating speed. By this, granule 8 from a hopper 28 are retained at a vertical transport part and form a blocking layer. Next, the flow regulating valve 40 is closed to the intermediate position, and a small amount of air less than that corresponding to the floating speed is introduced from the middle of the transport pipe 10 through an electromagnetic valve 34 and an air supply part 36 so as to fluidize the blocking layer. Then, the regulating valve 40 is further closed so as to temporarily increase a suction amount in the transport pipe, and the granules are raised and transferred in the layered state. By this repeated operation, the granules are sent to a separator 14 in the layered state. Thus, the granules which are easy to be damaged and abraded can be carried securely.

Title: Reflection type optical switch
Inventor: WATANABE KAZUAKI
IPC: G02F1/313
Filed: 1989-03-27
Abstract: PURPOSE:To suppress the absorption loss during waveguiding to a low level by forming an optical wave guide layer of a II-VI compd. semiconductor having a large energy gap. CONSTITUTION:The optical wave guide of the reflection type optical switch which is crossed with two pieces of optical wave guides at a certain angle and has an electrode for carrier implantation in the crossed part has at least clad layers 12, 14 of one conduction type consisting of the II-VI compd. semiconductor and the optical wave guide layer 13 of one conduction type consisting of the II-VI compd. semiconductor having the refractive index larger than the refractive index of the clad layers on a substrate 11. At least one layer of the respective layers are formed by selective epitaxial growth. Since the wave guide layer 13 is formed of the II-VI compd. semiconductor layer having the large energy gap, the shortening of the wavelength of the guided light is possible. The II-VI compd. semiconductor has a wide band gap. The absorption loss in the optical wave guide is suppressed to the lower level in this way even if the light (1mum band) of the same wavelength region as heretofore is guided.

Patent JP-H02251458-A (JP)
Title: Liquid jet recording head
Inventor: SEKIYA TAKURO
IPC: B41J2/05
Filed: 1989-03-27
Abstract: PURPOSE:To obtain a recording head of high efficiency in recording liquid discharging performance by generating bubbles efficively stably by a method wherein a resistance value of a first and a second electrodes satisfies a specific relation to a resistance value between both electrodes of a heating resistant layer. CONSTITUTION:A resistance value Re of a first electrode 7 and a second electrode 8 is a resistance value between A and B or between C and D. Further, since the electrode is generally formed of a low resistant material, a value of Re is small, and the resistance value between A and B may be taken as the resistance value between A and X. However, X is an optional point in an orifice line direction of the electrode 8. Though a resistance value Rh of a heating element 9 is a resistance value between B and C, that between B' and C', between B'' and C'',... are also the same value. In the case where a relation between Re and Rh is made to be 3R<=Rh and a pulsed signal voltage is applied, a heating resistant layer is effectively heated, and bubbles stabilized in recording liquid are made to be generated. Especially in a bubble jet ink jet recording head which is arranged at high density of 16 lines/mm or over, in order to driver stably at a higher speed than 4kHz in continuous driven response frequency, generation of bubbles by heating is effectively performed.

The size and the form of these electrodes are designed based on the energy enclosing logic. And AC power source 5 is connected electrically to electrodes 2 and 3 each, and thus the Ac voltage is applied to piezo-electric ceramic substrate 6 between electrodes 2 and 3. Then the AC voltage is applied to substrate 1 via electrodes 2 and 3 so that the orthogonal direction may be secured to the polarizing direction. Thus the good control is possible for the frequency response properties of the piezo-electric ceramic filter element by applying the voltage of the same or opposite direction as or to the polarizing direction with every half cycle.

CONSTITUTION:An aperture correction value is changed by th output voltage of a comparator driving circuit 10. Since the terminal of a delay line 13 is opened, an input signal e1 is reflected and returned to an input terminal and, when the electric angle of the delay line is theta, e1=ei costheta.epsilon<-js> and e2=ei.epsilon<js> are formed and an output signal of a differential amplifier is e1-e2=eiepsilon<-js> (costheta-1). A gain controlling circuit consisting of transistors 19-22, a current source 23 and a resistance 24 and the gain is controlled by an output signal from an amplifier 26. The gain controlled high frequency signal and the original signal are subtracted by a subtractor 25 and e2+K(e1-e2)=ei.e<-js>[1+K(1-costheta)]is found. The output signal is increased in prportion to the increment of frequency and shows the maximum at the frequency corresponding to costheta=-1. In said formula, K represents gain and the optimum quality of a picture can be always formed by controlling K.
