Title: Video signal clipping circuit
Inventor: MIZUGUCHI TAKASHI
IPC: H04N7/00
Filed: 1975-05-06
Abstract: PURPOSE: Development of the clipping circuit effective for digital video signal 1 and the digital signal 2 to set the clipping level are sent to the subtracting circuit 3. The decision circuit 4 opens the gate 5 only when the difference signal from the subtracting circuit 3 is positive (when the video signal level is higher than the clipping level), and the subtracting circuit 6 subtracts the difference signal from the video signal 1. When the vider signal level is lower than the clipping level, the video signal is firectly sent out of the circuit 7 as the output 7, and when higher than that, the difference signal representing the level difference is impressed on the subtracting circuit 6 through the circuit 3 and the gate 5. This defference signal is subtracted from the video signal 1 through the subtracting circuit 6, and the vider signal on the same level as the clipping level comes out as the output 7.

Title: Motor
Inventor: OKUDA HARUO
IPC: H02K5/08
Filed: 1987-03-11
Abstract: PURPOSE:To prevent a case from vibrating due to a leakage magnetic flux by disposing an iron plate on the outer periphery of a resin-molding layer of a motor. CONSTITUTION:When a voltage which is phase-controlled by a thyristor is applied to a motor, its rotor is rotated to rotate a fan 3 at a shaft 2. The vibration of the motor is alleviated since it is provided through cushion rubbers 6a, 6b in a case 5 so as not to be transmitted to the case 5. Since the outer periphery of the motor is further composed of a resin-molding layer 1, the magnetic flux of the stator in the motor is diffused externally over the layer 1, but it is shielded by ion plates 4a, 4b, 4c provided on the outer periphery. Thus, even if the case 5 is formed of the ion plates, the magnetic flux diffused over the layer 1 is shielded by the plates 4a, 4b, 4c, thereby eliminating the influence. Accordingly, the vibration of the case 5 does not generate a noise.

Abstract: PROBLEM TO BE SOLVED: To simply drive a ferroelectric liquid crystal element by using an easily gettable driver IC. SOLUTION: In an LCD signal generation circuit 16, respective signals are fixed to a low level in the state stopping an output to a liquid crystal optical element 10. Then, when a write-in instruction of an image to an LCD signal generation circuit 16 is received, the data D0-D3 are set in a high level in order to select the whole display data of a segment side, and prescribed pieces of clocks are applied by a fetch signal CL2 of the display data, and one pulse is applied by a latch signal CL1 of the segment side display data. Then, a DISP signal is set in a high level in order to erase a picture, and an AC signal MS and an inverted signal MC are applied (erasure pulse). Thus, a large voltage difference occurs in the liquid crystal optical element 10, and the whole erasure becomes possible easily and instantly.

Abstract: PURPOSE:To shut off automatically and sequentially a current protecting device of an electronic exchange by providing a control circuit for controlling an overcurrent protecting device and a timing circuit which drives at every certain interval when it receives a start signal from the outside. CONSTITUTION:A trip action of an overcurrent protecting device (NFB)5 is as follows: when a power source of negative 48V is shut off in a power chamber 4a, or when a key OP is operated; a relay A, a relay B and a relay W are sequentially actuated. A relay C is restored by the action of the relay B. The relays B and C alternately repeat the action and restoration accordingly. Moreover, a relay X is actuated due to the restoration of the relay B. While the relay B performs the action and the restoration twice, the relays W and X act one time. A control of the NFB5 is as follows: the relays W and X act alternately due to the action of the relay B, and operate from a relay 10 to (n) by a certain interval. At this point an earth closed circuit across an exchange 6 of negative 48V, a contact point 10c, the NFB5 and the power chamber 4 is formed by the action of the contact point 10c. A coil of the NFB5 releases a contact point 5a in said circuit. As a result, a power source unit 3 stops supply of a power source to a load circuit 2.

Title: Brushless motor
Inventor: UZUKA MITSUO
IPC: H02P6/21
Filed: 1982-04-02
Abstract: PURPOSE:To obtain a brushless motor which does not need a position detector such as a Hall element by obtaining switching signals of respective phases based on detection signals indicating that the induced voltages of a plurality of phases become the prescribed relationship. CONSTITUTION:Assume that the output of a comparator 3U is H, a transistor TrQ is ON and a coil 1U is energized, TrQ2-Q5 and Q9 are OFF, while Tr Q6-Q8 are ON. Accordingly, the output of a comparator 3U is H, the outputs of a comparators 3v, 3w are L, and coils 1v, 1w are not energized. Since the voltage at the point (V) becomes VS at a time t2, the output of the comparator 3v changes from L to H, the TrQ2 becomes ON, and the coil 1v is energized. Since the output of the comparator 3U becomes L, the TrQ1 becomes OFF, thereby turning the TrQ9 ON and allowing Q6 to maintain OFF and the output of the comparator 3w holds L, the coil 1U is interrupted, and the energization of the coil 1w is inhibited. The circuit state of each phase is shifted to the phase at the adjacent phase at a time t3, and similar operation is performed.

Title: Structure of reinforcing construction method for banking having wall surface
Inventor: KASAI MASAAKI
IPC: E02D17/18
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To provide frictional force equal to the strip with ribs by the terre armee method by using a reinforcement bar with ribs as a reinforced earth reinforcing material for banking having a vertical wall. SOLUTION: Ribs 1 are fitted to a reinfocement 2 on the market so as to constitute a reinforced earth reinforcing material. The interval and the size of the rib 1 are decided from strength of frictional resistance between iron and banking material, mutual relation of reinforcements, and the like. For joining together a surface panel 3 and the reinforcement 2, steel plates 8, 9 provided with bolt 7 holes are welded to the end part of the reinforcement bar 2 and the surface wall panel 3 and they are joined together by the bolt 7, without using a turnbuckle. Otherwise, the end part of the reinforcement bar 2 is bent, and the part is locked with a joint part welded to the surface panel 3.  Stability of a reinforced earth wall does not depend upon the surface wall 3, but depends upon the reinforcing material, joint of the surface wall panel 3 with the reinforcement bar 2 does not require so much tensile strength, if only it can deal with sinking, and it is enough to be a soft and simple construction. Consequently, the reinforcing material can be constituted at low price according to required strength.

Abstract: PURPOSE: To reduce resistance against the flow in the discharge direction from a compression chamber and to enable the reduction in a loss in a discharge system, by a method wherein a fluid diode, in which a discharge direction from the compression chamber forms a forward flow, is formed in a discharge port.  
     CONSTITUTION: An eddy type fluid diode 9, serving as a fluid diode in which a discharge direction from a compression chamber 6 forms a forward flow, is formed in a discharge port 3. As illustarted in the drawing, the eddy type fluid diode 9 consists of a cylindrical eddy chamber 10, an inlet 11 which is opened concentrically in the direction with respect to the center shaft of the eddy chamber 10 and connects together the eddy chamber 10 and the compression chamber 6, and an outlet 12 which is opened in the tangential direction with respect to the eddy chamber 10 and connects together the eddy chamber 10 and the downstream side of the discharge port 3. When a coolant gas is in a condition to exhaust through the eddy type fluid diode 9 from the compression chamber 6, this action causes a smooth flow of the coolant gas through the eddy chamber 10 from the compression chamber 6 to the outlet 12, whereby the flow path resistance can be reduced and a flow path can be decreased even at a high-speed rotating time.

Abstract: PURPOSE:To eliminate the need for precise working accuracy of a journal and to reduce cost by providing a foil bearing provided radially with leaves having electricity between the journal and air bearing hole. CONSTITUTION:A rotor 30 rotates in a floating state when a plunger 39 is attracted by a coil 41 for thrust while high-frequency current is kept passed to a stator coil 40. A relative speed of the journal 31 and the foil bearing 36 increases and air flow 50 is generated in the same direction as the rotating direction of the journal 31 by the viscosity resistance of the air when the number of revolutions of the rotor 30 increases. The air flow 50 flows into a spacing 49 between the journal 31 and the leaves 48. Since the spacing 49 is narrowed to a wedge shape, the air flow 50 increases its pressure as the air flow is confined into the deep part of the spacing 49. The leaves 48 are then elastically deformed outward to increase the spacing and, therefore, the journal 31 rotates at a high speed without contact with the leaves 48 while the journal is held afloat radially in the air bearing hole 34.
