Title: Howling suppression controller
Inventor: TAKEKURA HIROYUKI
IPC: H03G3/30
Filed: 1979-12-31
Abstract: PURPOSE:To suppress the howling, by recognizing the howling based on the change of the extreme value of the input signal on the time axis in a signal loudspeaking system and then controlling the gain of an amplifier of the input sigal based on the recognized holwing. CONSTITUTION:The signal sent from the sound collecting microphone Mm is supplied to the howling recognizing part HRD. At the part HRD, the extreme value of the input signal is detected, and the howling recognition signal is sent to the gain control signal generating part CSG in case the codes of the adjacent extreme values are inverted while the extreme value becomes to a prescribed number of units and in case the absolute value of the subsequent extreme value becomes larger than the absolute value of the preceding extreme value among the adjacent extreme values. The part CSG sends the gain control signal to the variable gain amplifier VA to change the gain. Thus a good suppression is possible for the howling by changing the gain of the signal transmission line.

Title: Schottky barrier diode
Inventor: OMUKAE TAKESHI
IPC: H01L29/872
Filed: 1985-08-06
Abstract: PURPOSE:To reduce the forward voltage of a Schottky barrier diode, by providing with one conductive type of a separating region with a higher impurity concentration reaching from the epitaxial layer surface to the semiconductor substrate surface around the epitaxial layer, and the one conductive type of a buried layer formed at a section in the separating region on the semiconductor substrate. CONSTITUTION:An N<+> type buried region 3 is formed at least on a section in the separating region 6 by diffusing selectively antimony on a semiconductor substrate 2. Accordingly, since the current path flowing into the semiconductor substrate 2 from the barrier metal electrode 7 can be shortened, the resistance at this section can be reduced. On the other hand, an N<+> type separating region 6 is formed so as to reach from the epitaxial layer 4 surface to the N<+> type semiconductor substrate 2 surface around the N-type epitaxial layer 4. Since the N<+> type separating region with a higher concentration than the N-type epitaxial layer 4 may be formed and thus a portion of current may be flowed into the N<+> type separating region 6, increase of the boundary area between the semiconductor substrate 2 and the epitaxial layer 4 of the Schottky barrier diode and thus decrease of the resistance can be attained.

Title: Device for packing radioactive material adsorbent
Inventor: SAKURAI MANABU
IPC: G21F9/00
Filed: 1987-07-13
Abstract: PURPOSE:To decrease the amt. of the used radioactive material adsorbent to be generated by decreasing the amt. of the radioactive material adsorbent to be packed into a basket toward the down stream in the pass direction of radioactive fluid. CONSTITUTION:The radioactive fluid supplied from an inlet nozzle 10c of a device 10 for packing the radioactive material adsorbent flows into the annulus passage between a column cylinder 10 and an outside pipe 11a of the basket. This radioactive fluid flows from a flow inlet 13a of the pipe 11a toward a flow outlet 13b of an inside pipe 11b and flows diametrally in the packed part of the radioactive material adsorbent 12. The radioactive material in the fluid is adsorbed by the adsorbent 12 at the time of flowing of the radioactive fluid and while the dose is thereby decreased, the fluid flows through the inside pipe 11b and is discharged as the radioactive fluid cleaned to a low dose from an outlet nozzle 10d. The amt. of the adsorbent 12 packed in the basket 11 is gradually decreased toward the down stream in the flow direction of the radioactive fluid and, therefore, the amt. of the used radioactive material adsorbent to be generated is decreased with substantially no degradation in the radioactive adsorption power over the entire part of the device 10.

Title: Method for detecting air leakage
Inventor: MATSUSHITA TSUTOMU
IPC: G01M3/20
Filed: 1985-08-06
Abstract: PURPOSE:To make it possible to detect the air leakage of a pressure container, by mounting a color forming material to the matching surfaces of a pressure container by coating or in a state held therebetween and injecting a fluid discoloring said color forming material in the pressure container. CONSTITUTION:For example, when the leakage of upper and lower matching surfaces is detected in the model test of a transparent resin pressure container, litmus paper is placed on the lower matching surface and the upper matching surface is fitted to the lower one to be clamped thereto by bolt clamping. Next, gas for discoloring the litmus paper, for example, ammonia gas or hydrogen chloride gas is injected in the clamped container. If there is air leakage, ammonia gas or hydrogen chloride gas is instantaneously reacted with litmus to discolor the litmus paper to red or blue and the leaked part is accurately shown by coloration. By this method, the visualization of air leakage of the pressure container is enabled and the state of air leakage can be confirmed.

Title: Switching regulator
Inventor: FUKUCHI TAKESHI
IPC: H02M3/338
Filed: 1992-06-30
Abstract: PURPOSE:To prevent a runaway or the destruction of a load connected by putting down an abnormally high voltage appearing in an output and by regulating a drop of an output. CONSTITUTION:Reference voltages Vs1, Vs2 and Vs3 are so set as to meet Vs1<Vs2<Vs3. When an output V1 which is controlled by the voltage Vs1 exceeds the voltage Vs2, an overvoltage protective circuit 6 causes a controlling circuit 2 to stop switching of a FETQ1 for preventing an overvoltage. Due to that time lag, the output V1 increases further. However, a Zener diode ZD3 of the operating voltage Vs3 starts working and it clamps the output V1 and therefore there is no overvoltage appearing, not even for an instant. When power supply is stopped due to turning off of a power supply or other reasons, a voltage drop of an output V2 of a rectifying and smoothing circuit for detection 7 is detected and then a discharging circuit 8 starts working and a capacitor C4 is discharged and the output V1 is dropped down rapidly.

Title: Light-emitting diode and display device using the diode
Inventor: YAMADA MOTOKAZU
IPC: H01L25/075
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To improve visibility and color mixture property by making a side which is parallel to a line formed by connecting elliptic focuses of a mold member longer than a vertical side and making condensing by a mold member and a cup shape approximately the same. SOLUTION: A mold member 106 of a light emitting diode is elliptic viewed from a light emission observation surface side and a side of a cup 102 which is parallel to a line between focuses of the mold member 106 is longer than a vertical side and condensing by the mold member 106 and a cup outer shape are approximately the same. The light emitting diode has a wide view angle in right and left directions and a light emission surface is not viewed small distortedly to an elliptic mold member even when recognized visually from an area near a front. If each light emitting diode is arranged in a matrix at an interval of 6mm one by one and a light emitting device connected to a driving device is formed, a light emission surface is large in right and left directions, and light emission areas of each light emitting diode are close.  Therefore, a light emitting device of high color mixture property can be realized.

Title: Variable gain amplifier
Inventor: TAKEUCHI AKIHIRO
IPC: H03G3/04
Filed: 1980-12-10
Abstract: PURPOSE:To obtain a stable amplifier, by changing an opened loop gain simultaneously with the change of the negative feedback rate so that the changed feedback quantity becomes constant. CONSTITUTION:An input voltage is given to an inversion input 35 of an amplifier 34 from an input terminal 37 of an opened loop system, and a voltage is  given to a noninversion input 36 from a feedback circuit consisting of a variable resistance Rf and a fixed resistance Re. The collector terminal of the last-stage transistor TR38 is the output of a closed loop system. The variable resistance Rf is a part of the load resistance of the TR38; and since the gain of the last stage is changed in proportion to the value of the variable resistance Rf in case of Re<<Rf, an opened loop gain A of the circuit is proportional to the value of the resistance Rf. A feedback rate beta and the opened loop gain A satisfy equation Abeta=(R2+1)/4R-(1/2) (R is the stagger ratio of the amplifier), and the opened loop gain A and the feedback rate beta are changed simultaneously by  changing the value of the resistance Rf to make a negative feedback quantity  1+Abeta constant.
