Title: Automatic tracking measuring machine
Inventor: INABA HIROSHI
IPC: G01C15/00
Filed: 1993-04-21
Abstract: PURPOSE:To prevent drop of the tracking accuracy in case the diatance has increased, by calculating the ratio of the reflex area to the search area so that the search area at a closer time is approached when the distance between the body of a measuring machine and an object to be measured is large. CONSTITUTION:The body 8 of a measuring machine is rotated 5 in the horizontal direction and also rotated 7 in the vertical direction. A distance measuring optical system 9 emits an infrared laser beam from the machine body 8 and receives the reflected light from an object to be measured 2. and a control device CPU calculates the distance from the object 2 on the basis of the light reception output. A scanning optical system 10 performs the search and scan by emitting an infrared laser beam having different wavelength and receives the reflex light from the object 2 lying within the search scope. The CPU makes scanning in the horizontal and vertical directions with a specific angle and calculates HM/TH or TH', where TH is search area of the distance L1 between the object 2 and body 8, TH' is area of the distance L2 from another object 2', and HM is the reflex area of the objects 2, 2'. When L1<L2, the area TH' is narrowed to generate THS so that no reflex light from object(s) 300 other than the applicable object 2 comes incident to the machine body 8. This allows preventing deterioration of the tracking accuracy.

Title: Communication terminal
Inventor: MOCHIZUKI MASAHIRO
IPC: H04N1/32
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To quicken the start of transmission of a CM signal from a caller station in the V.8 protocol. SOLUTION: In the conventional V.8 protocol, a signal component of 2100 Hz from an opposite equipment is detected, it is recognized that the 2100 Hz signal is an ANSam signal at least for 450 mmsec and then a CM signal is transmitted. But in this embodiment, when the signal component of 2100 Hz (independently of the ANSam signal component or a CED signal component) is detected (affirmative in the step 308), the transmission of the CM signal is quickly started (step 310). The transmission start of the CM signal is quickened in this way and the execution time of the V.8 protocol is reduced prior to the V.34 protocol.

IPC: E02D5/80
Filed: 1992-04-15
Abstract: PURPOSE:To prevent a jet of groundwater, outflow of grout, or the like, so as to perform accurate execution, by using for drilling, high specific gravity stabilized liquid to a drilling mouth consisting of a hollow pipe driven in the execution position of a ground anchor under water pressure. CONSTITUTION:At first, a deep well 3 is provided on the ground where a ground anchor is executed and surrounded with a land slide protection wall 2, and water is pumped from the well so as to lower the groundwater level to 4'. Next, pit excavation is performed up to a prescribed depth in this condition, a hollow pipe 9 is driven on the anchor execution position of a pit bottom under water pressure less than groundwater level 4, and concrete is placed on the pit bottom so as to form a mat slab 7. Next, while pumping, ordinary drilling is performed using high specific gravity stabilizing liquid, setting the hollow pipe 9 as a drilling mouth. In this case, water pressure B outside the hole is higher than the stabilizing liquid pressure C in the drilling hole in the depth alpha part, but inflow of groundwater and the like into the hole is prevented, because the hole is surrounded with the hollow pipe 9. In the depth betapart, the stabilized liquid pressure C inside a drilled hole is higher than water pressure B outside the hole by the high specific gravity stabilized liquid 10, and hence the hole wall can be protected.

Title: Automatic lubricator for chain conveyer
Inventor: WATANABE TOSHINOBU
IPC: B65G45/08
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To keep distance between an automatic lubricator and a grease nipple constant, and allow lubrication even when a conveyer meanders, by providing an energizing means which transfers an automatic lubricator toward a ring plate of a chain conveyer and rollers which are attached to the automatic lubricator through a pair of ARMS. SOLUTION: An automatic lubricator 5 is energized so as to always move to a chain conveyer (conveyer) 1 side by a spring. On the side facing the conveyer 1, arms 17 which has a contacting roller 18 at its top and extends in the direction orthogonal to the conveyer 1 are mounted. Distance between a pair of arms 17 is equal to or a little larger than the interval between grease nipples 4 so that one of two contacting rollers 18 contacts with a ring plate 3 close to the automatic lubricator 5. Therefore, even if the conveyer 1 meanders and the grease nipples 4 displace back and forth, distance between the automatic lubricator 5 and the nipple 4 is kept constant, and lubrication is allowed.

Title: Control circuit for thyristor rectifier
Inventor: NONAKA MASAAKI
IPC: H02M7/162
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To achieve stable operation of a thyristor rectifier by supplying a triangular wave generating means with a correction signal obtained by transforming a voltage signal proportional to frequency, and adding a crest value correcting means that makes constant the crest value of triangular waves from the triangular wave generating means independently of the frequency of input alternating voltage. SOLUTION: An alternating supply voltage VG of an alternating-current generator 1 is inputted to a F/V converter 9, and a voltage signal proportional to its frequency is outputted to a crest value correcting circuit 10. A correction signal obtained by transformation in the crest value correcting circuit 10 is supplied to a triangular wave generating circuit 4, which is operated so that the crest values of triangular waves at half period points of the alternating supply voltage VG will be constant independently of the frequency of the alternating supply voltage VG. This modifies triangular waves into waveform with constant phase gradient, and prevents fluctuation of a reference signal VAVR from being limited by the upper and lower limit values of its allowable fluctuation range even during significant fluctuation in power supply frequency.  Thus, it is possible to operate a thyristor rectifier 2 with stability.
