Filed: 1986-12-04
Abstract: PURPOSE:To enable the position of a buried article to be detected with a high accuracy and by a simple constitution by specifying the position of the top of the echo image of the buried article and the position of the other one point. CONSTITUTION:A movable truck 1 is composed of a transmitter 10 and an antenna 11 for emitting radio wave toward a buried article 3, a receiver 12, a receiving antenna 13 and a range sensor 14 for generating one pulse at every unit distance movement of the truck 1.

Abstract: PURPOSE:To improve the efficiency of the operation to strip the intermediate part of the jacket of a coated optical fiber by providing a pair of upper and lower stationary blades and a pair of upper and lower moving blades, fixing the moving blades to a moving blade rest which is freely slidable with a stripper body and inclining the moving blades in a cutting direction with respect to the surface of the coated optical fiber. CONSTITUTION:The stripper body 1 is provided with a pair of the upper and lower stationary blades 8 and a pair of the upper and lower moving blades 13. The moving blades 13 are fixed to the moving blade rest 10 which is freely slidable with the stripper body 1. The moving blades 13 are inclined toward the cutting direction with respect to the surface of the coated fiber T. The coated fiber T is inserted between the stationary blades 8 and the moving blades 13 and after both the blades are bitten to the surface of the jacket, the moving blades 13 are moved toward the stationary blades 8, then the surface is cut and stripped. The surface of the jacket is retained by the stationary blades 8 at this time, by which the deviation of the surface is regulated. Since the jacket is scored by the stationary blades 8 at the end point of the cutting, the surface is detached simultaneously with the end of the cutting. The efficiency of the operation to cut the intermediate part of the jacket is improved in this way.

Title: Coding and decoding device for moving picture
IPC: H04N19/14
Filed: 1992-10-28
Abstract: PURPOSE:To obtain high picture quality with less information quantity by selecting in-block prediction coding for coding for a contour of a picture. CONSTITUTION:A block difference signal S2b from a block processing circuit 28 and a discrete cosine transformation signal $3 from a discrete cosine transformation circuit 11 are fed to a coding system changeover discrimination device 3, and when the discrete cosine transformation system is more advantageous, the device 3 generates a coding system switching signal S20 to throw 1st and 2nd selectors 4A, 4B to the position of the discrete cosine transformation coding input terminal (a) thereby allowing a discrete cosine transformation coding processing section 1 to encode the block processing difference signal S2b. On the other hand, when the compression rate for information by the discrete cosine transformation system is disadvantageous, the coding system switching signal S20 is used to throw the 1st and 2nd selectors 4A, 4B to the position of the discrete cosine transformation coding input terminal (b) thereby allowing an in-block prediction coding processing section 2 to execute the coding of the block processing difference signal S2b.

Title: Production of platy polystyrene resin foam
Inventor: KITAHAMA TAKU
IPC: C08J9/14
Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To produce a low-density polystyrene resin foam even when a blowing agent other then a chlorofluorohydrocarbon(CFC) is used. SOLUTION: An expandable composition prepared by kneading a stock resin comprising a polystyrene resin and a blowing agent is extrusion-foamed to produce a platy polystyrene resin foam. In order to heighten the pressure of the resin near the lip of the extruder by keeping the MFR of the stock resin at 1-10g/10min at which the foamability and moldability into a foam are not impaired, the z-average molecular weight (Mz) of the stock resin is selected so as to be 5×10<4> or above to heighten the content of high-molecular weight component in the stock resin. The Mw/Mn ratio is selected at 3.2 or above so as to broaden the molecular weight distribution of the stock resin and to permit the presence of a moderate amount of a low-molecular weight component. Thus the existence of the low-molecular-weight component assures the flowability of the stock resin during blowing.

Title: Pulse width modulation type inverter device
Inventor: KATTO MASAYUKI
IPC: H02M7/48
Filed: 1988-11-17
Abstract: PURPOSE:To improve noise characteristic and leak current characteristic by detecting inverter output leak current under actual installation conditions and selecting the reference voltage waveform according to the level of the output leak current such that 3-arm control is made for low leak current while 2-arm control is made for high leak current. CONSTITUTION:In a leak current detector 80, a reference voltage generator 40 determines a 3-arm control reference voltage waveform having good noise characteristic based on the output voltage and output frequency at that time if the inverter output leakage current is lower than a predetermined level and provides the reference voltage waveform to a PWM circuit 60. At this time, motor noise is quite low and the leak current is also low because of the 3-arm control. If the inverter output leakage current level is higher than the predetermined level, the reference voltage generator 40 determines 2-arm control reference voltage waveform based on the output voltage and output frequency at that time and provides the reference voltage waveform to the PWM circuit 60 thus lowering the leakage current level.

Title: Control device for automatic transmission
Inventor: KUSAFUKA MUNEO
IPC: F16H61/04
Filed: 1994-10-31
Abstract: PURPOSE: To prevent generation of engaging shock or engine racing when an automatic transmission is shifted from the released condition of the first clutch to the perfect engaged condition. CONSTITUTION: When difference between input rotating speed and output rotating speed is not changed while the released condition of a clutch is formed, oil pressure supplied to a hydraulic servo C-1 is heightened so as to make the clutch on the side of engaged condition, and when the difference is changed, oil pressure supplied to the hydraulic servo C-1 is lowered so as to make the clutch on the side of released condition. When an operator operates take-off and a vehicle is detected to be shifted from the stop condition to the take-off condition, set shelf pressure is added to base pressure so as to heighten the oil pressure supplied to the hydraulic servo C-1, and hence the clutch is made into the half engaged condition.  When oil pressure supplied to the hydraulic servo C-1 is lowered by a pressure decreasing means 956 after being heightened by a pressure increasing means 955, the oil pressure before being lowered is set as the base pressure.
