Title: Method of preventing liquefying of sandy ground
Inventor: NAGATAKI YOSHIAKI
IPC: E02D3/10
Filed: 1984-07-13
Abstract: PURPOSE:To prevent liquefying of sandy ground, by a method wherein a porous pipe, into which a tube filled with a pressured air is inserted, is penetrated into a sandy ground, and the air in the tube is exhausted when earthquake occurs. CONSTITUTION:In a pile A, a tube 2 is inserted into a porous pipe 1 having a number of through-holes 1a in the whole surface thereof. Pressured air is sealed in the interior of the tube 2, and the through-holes 1a are watertightly closed with the tube 2. A pile A is penetrated into a sandy ground C right under or around a structure B. When earthquake exceeding allowable acceleration occurs, an electromagnetic valve 3 is opened by an earthquake gauge and a control device D to momentarily discharge the air in the tube 2. In which case, the tube 2 is contracted for closing to suck gap water in the sandy ground C into the porous pipe 1 through the through-holes 1a, resulting in reduction in the gap water pressure in the sandy ground C and prevention of liquefying of the sandy ground C.

Title: Tunnel surveying method
Inventor: KONISHI TAMOTSU
IPC: G01C15/00
Filed: 1993-05-24
Abstract: PURPOSE: To provide a tunnel surveying method by which a turning point-type survey can be carried out automatically within a short time. CONSTITUTION: Prisms P for collimation are successively fixed in the axial direction on the inner wall of a tunnel and at the same time, a surveying carriage 1 which runs while being guided by running rails is driven. An automatic searching-type surveying equipment 2 which automatically searches the prisms for collimation and surveys the distance from a reference point of the surveying carriage to each prism for a collimation is mounted on the surveying carriage. The surveying carriage stops running temporarily at every nearly intermediate position between the prisms for collimation arranged in the axial direction of the tunnel. At the time of temporary stopping, the automatic searching-type surveying equipment surveys the prism for collimation at already known position on this side and computes three-dimensional position of a reference point of the surveying carriage.  Then, the automatic searching-type surveying equipment surveys a next prism for collimation on one deeper side and computes its position and thus successively computes the three-dimensional positions of the prisms for collimation step by step toward the deeper side.

Title: Broadcast output monitor
Inventor: NAKAGAWA KEISUKE
IPC: H04H20/12
Filed: 1994-06-27
Abstract: PURPOSE:To obtain the broadcast output monitor not destroyed by a high voltage. CONSTITUTION:A magnetic field around a feeder 12 through which a broadcast output is sent from a radio broadcast equipment 11 is detected by an electromagnetic wave detector 14 and converted into an optical signal. A monitor 16 monitors the presence of the conversion output. Since the electromagnetic wave detector 14 is isolated from the feeder 12, it is not required to take its withstand voltage into account. If the detector is faulty, since no effect is imposed on the feeder, the output is monitored without giving hindrance to the broadcast. Since the signal is sent while being converted into an optical signal, the effect of electric induction such as lightning surge onto the detection result is avoided.

Filed: 1979-11-07
Abstract: PURPOSE:To exactly control a flash by providing the switching means for controlling a flash of the light emission part when a signal of the photometric circuit has attained to the prescribed value. CONSTITUTION:The phototransistor PTr9 detects a reflected ray of the object to be photographed by light emission of the discharge tube at the same time when the transistor Tr7 is turned on, and a current corresponding to the amount of light is made to flow. This current is integrated by the integral capacitor 32, and when the voltage has attained to the prescribed value, SCR27 is turned on, as a result, the electric charge of the trigger capacitor 28 is applied to the trigger coil 29, its voltage is raised, and the raised voltage operates the quenching tube 25. In this case, since the internal resistance of the quenching tube 25 is smaller than that of the discharge tube 24, the electric charge from the main capacitor 17 almost flows into the  quenching tube, and light emission of the discharge tube is stopped. In this way, a flash-light of the light emission part can be controlled exactly.

Abstract: PURPOSE:To realize a variable speed control operation with the highest efficiency  without being affected by changes in loads and in supplied power by a method wherein  automatic regulation is effected wherein the current in the induction motor is rendered  minimum at a control frequency. CONSTITUTION:A current signal 1 detected by a current sensor 8 and stored in a memory 9 is compared with a newly detected signal i in a comparator 10, and then  signals (a) and (b) are respectively yielded when I<i or I>i. A voltage control command circuit 11 generates a signal S1 when a certain length of time has passed since a  frequency shift signal e1 was outputted, or when an output (a) is present and a voltage  increase signal S2 was present in the previous cycle, or when an output (b) is present  and a voltage decrease signal S1 was present in the previous cycle. The command  circuit 11 generates a signal S2 when an output (a) is present and a signal S1 was  present in the previous cycle or when an output (b) is present and a signal S2 was  present in the previous cycle. The inverter output voltage is stepped up or down by  standard quantities by a voltage control circuit not illustrated, whereby output voltages are automatically regulated for the induction-motor current to remain at the  minimum, which in turn realizes a variable speed control run with the highest possible  efficiency not affected by fluctuations in the power source or the like.

IPC: F02B25/16
Filed: 1995-05-08
Abstract: PURPOSE: To reduce incurring of a loss due to the generation of turbulence in the process of opening of a scavenging hole by a piston valve through simple variation of structure by a method wherein the lower part of a cylinder surface and the inlet of a scavenging passage form a connection surface in a curved surface having a specified radius and a curved surface having other specified radius is formed at the upper part of a scavenging hole and the upper part of a piston. CONSTITUTION: The under surface of a cylinder 7 and a scavenging passage inlet 4 are interconnected through a curved surface having a radius of 2mm or more. Further, a curved surface having a radius of 1mm or more is formed at the upper part of a scavenging hole 6 and the upper part of a piston 3. First, the scavenging hole 6 is opened during a compression process and air-fuel mixture is brought into a state to be pushed out from the lower part of the piston 3. In this case, since the inside diameter of the cylinder and the inlet 4 of the scavenging passage are interconnected through a curved surface, the change of air-fuel mixture density and lowering of a velocity of flow due to the generation of turbulence are prevented from occurring.  Since, when air-fuel mixture is fed through the scavenging hole 6, a curved surface is formed at the upper part of the scavenging hole 6 and the upper part of the piston 3, the change of air-fuel mixture density due to the generation of turbulence and the generation of carbon due to adhesion of fuel on the upper surface of the piston and the inner surface of the cylinder are suppressed.
