Title: Construction method for continuous subsoil improver and trench excavation device used therefor
Inventor: GUNJI KOICHI
IPC: E02D3/12
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of the tilt of a cutter post until the completion of the construction of one zone by applying the constitution that an endless chain is made to circulate in the descending direction of a zone positioned forward of the travel direction of a trench excavation device across the cutter post at the time of the travel of the device, and the lower end of the cutter post is kept below the lower end thereof observed at the time of the previous travel when the device is traveling. SOLUTION: During the travel of a trench excavation device 1, an endless chain 3 is circulated in the descending direction of a zone positioned forward of a travel direction across a cutter post 2. Also, during a plurality of times of the travels of the trench excavation device 1, the lower end of the cutter post 2 is kept below the lower end thereof observed during the previous travel. As a result, cutting and agitation claw 4 passing along the lower end of the cutter post 2 scrapes a subsoil in a direction opposite to the travel direction of the trench excavation device 1. In addition, the cutter post 2 can be made to travel at a constant speed only by causing the upper end thereof to move in a travel direction. According to this construction, the cutter post 2 can be prevented from tilting from an initial state at the start of a construction work.

Filed: 1989-05-16
Abstract: PURPOSE:To prevent an image misalignment from being generated in a joint of an image recorded by a specific scan and an image of a scan being adjacent to this scan by constituting this recorder so that an exposure is executed synchronously with a moving speed of a photosensitive body, and it is brought into contact with recording paper and transferred after executing the exposure of a 1-scan portion. CONSTITUTION:A clock pulse is supplied to a counter 46 from an oscillator 42, and by a generation period outputted from a ROM 45, a read-out pulse is generated. A picture signal stored in a RAM 48 is read out in accordance with an address designated by a read address generating circuit and its read-out pulse, sent to an exposing part 23, and an exposure is executed synchronizing with a moving speed of a photosensitive body 21. In such a way, by constituting this recorder so that it is brought into contact with recording paper and trans ferred after executing an exposure of a 1-scan portion, it does not occur that an image is influenced by a variation of a moving speed of a carriage, and an image misalignment is not generated in a joint of an image recorded by a specific scan and an image of a scan being adjacent to this scan.

Title: Measuring apparatus for searching laying route of power cable and trouble point
Inventor: MIZUNIWA TAKASHI
IPC: G01R31/08
Filed: 1985-06-05
Abstract: PURPOSE:To simultaneously search a laying route and a trouble point within a short time, by simultaneously inputting a signal with first frequency and a signal with second frequency to a power cable and detecting the magnetic field, which is generated by the power cable, by a magnetic field detection coil. CONSTITUTION:A high frequency transmitter 1 generates a signal with first frequency, for example, of about 10kHz suitable for searching the laying route of a power cable 2 and a signal with second frequency, for example, of about 1kHz suitable for searching the trouble point of the power cable 2 to simultaneously apply both signals to the power cable 2. Because the power cable to which both signals were inputted generates a magnetic field M therearound, said magnetic field M is detected by a magnetic field detection coil 4 to supply the detection signal to a tuner 5. The tuner 5 separates the supplied detection signal into the signal with the first frequency and the signal with the second frequency before amplifies the same. Two separated and amplified signals are respectively supplied to monitors 6A, 6B to be displayed thereon and, by this method, the laying route and the trouble point can be simultaneously detected.

Title: Surge protecting element
Inventor: SHIMODA YOSHIO
IPC: H01L29/861
Filed: 1995-05-22
Abstract: PURPOSE: To independently design break-over voltage and to decrease junction capacitance by a method wherein the impurity concentration of the N-base layer in a through hole is made higher than the other part, and the P-N junction, having the impurity concentration grade larger than the other junction part, is provided directly under the through hole. CONSTITUTION: When surge voltage is applied to an electrode 1, junctions J2 and J2' are invertedly biased. As the junction J2' has the impurity concentration gradient larger than the junction J2 and it has low break-over voltage, avalanche currents Ia1 and Ia2 are allowed to flow through the junction J2. When the voltage drop, generated by the resistance of N-base, exceeds the built-in potential of a junction J1, the injection of carrier is started from a P-emitter, a forward direction thyristor is switched to on-state, and a large current ION is allowed to flow. To be more precise, as the break-over voltage is determined by the junction J2', the impurity concentration of the junction J2 can be made low, and the junction capacitance can be sharply decreased on the whole element.

Each metal film 3 is deposited on both the surface and the rear of the substrate 1 with wiring materials which have coefficients of expansion that are almost the same as those of above both faces. The same wiring layers 4 and 5 are formed on the surface and the rear of the substrate 1. When heat treatment is performed in this process, the substrate 1 is thus sandwiched between the wiring materials which have thermal expansion coefficients that are the same as those of above both faces and then, such a state of the substrate lessens its thermal deformation and prevents the development of cracks in the insulating film 2 of the surface as well as in each wiring and then, the yield is improved.

The photodetection surface of the four-division photodetector 7 is positioned at the midpoint between the focuses P and Q almost perpendicularly to an optical axis of incidence. Two light spots T and S of the same size which are nearly semicircular are formed on the four-division photodetector 7. The position of the four-division photodetector 7 is adjusted in the photodetection surface so that uniform light is received in four photodetection areas. The sum of electric signals obtained in diagonal photodetection areas of the four-division photodetector are calculated and their difference is further calculated by a differential amplifier 8 to obtain the focus error signal.
