Title: Device and method for detecting sheet paper and preparatorily biting nail for sheet paper processing machine
Inventor: HAINAA RUKUSEN
IPC: B65H7/02

Abstract: PURPOSE: To prolong the acceleration time of paper sheets by providing a scanning range for detecting a paper sheet surface at the stop position of a front stop in a means for accelerating aligned paper sheets to a speed required for transferring them to a paper sheet processor. CONSTITUTION: The paper sheet 20 is introduced to a gap range between a gripping pawl 4 and a pawl base 5, aligned on the stop surface of the front stop 6 and detected by a reflection type photosensor 11, then the gripping pawl 4 is immediately turned downwards to the stopped paper sheet 20 and the paper sheet is captured by the gripping pawl 4 and the pawl base 5. When the stop surface 4 of the front stop 6 is turned downwards, a pre-gripping pawl arm 3 is accelerated and turned until the paper sheet 20 is transferred to a transfer drum 2 on the lower side of a table plate 1. At the time of transfer, the gripping pawl 4 is turned in the direction of separating from the pawl base 5 and transferred to the transfer drum 2. Thus, since an acceleration stage is started in an early stage, acceleration is gently performed and vibration or the like is reduced.

Title: Method for retention of water in soil by using synthetic high-molecular gel
Inventor: ORIHARA KATSUO
IPC: C09K101/00
Filed: 1986-07-08
Abstract: PURPOSE:To retain the moisture in soil, by crushing a high-molecular gel obtained by the heat treatment of a mixture of polyvinyl alcohol with polyvinylpyrrolidone, and mixing the crushed gel with soil. CONSTITUTION:A mixture of polyvinyl alcohol with polyvinylpyrrolidone is heat-treated to give a high-molecular gel, which is crushed and mixed with soil. The use of a high-molecular gel obtained by the crosslinking treatment of a mixture of polyvinyl alcohol with polyvinylpyrrolidone is desirable since it reduces the loss of gel due to dissolution in water and also improves the effect of controlling the evaporation of water in soil. To produce the above- mentioned high-molecular gel, for example, polyvinyl alcohol is mixed with about 60-90wt% polyvinylpyrrolidone in an aqueous solution, and the mixture is heat-treated at about 190-230 deg.C for about 1-30min in the air. The high- molecular gel thus obtained is immersed in a water of about 40 deg.C for about 96hr to remove the part that is dissolved in the water, then dried and crushed.

IPC: H04B10/50
Filed: 1994-07-11
Abstract: PURPOSE:To attain the long term service by battery driven by reducing the power consumption of the optical signal transmitter. CONSTITUTION:Since the same pattern of a signal as that of a signal (a) to be sent has been used for photoelectric conversion in a conventional optical signal transmitter for the transmission of the signal, a large current should have been supplied to a photoelectric conversion section, resulting that the power consumption is increased, and the power consumption is remarkably reduced by generating an optical pulse signal only at each of leading and trailing edges of the signal to be sent for the transmission as shown in figures (b), (c) or (d) in this embodiment.

Abstract: PURPOSE: To locally cool a grinding wheel by arranging a cooling nozzle on one end of an arched frame so as to deliver a coolant in the tangent direction of the grinding wheel by communicating with a first guard inside passage. CONSTITUTION: A cooling nozzle 94 connected to a passage of a high pressure coolant is arranged on one end of an arched frame 64. The cooling nozzle 94 is turned in the tangent direction of a grinding wheel 66 so as to deliver the coolant to a position where the grinding wheel 66 crosses a work member. Since the direction of the coolant delivered from the cooling nozzle 94 is the same as the rotational direction of the grinding wheel 66, the coolant is delivered at the substantially same speed as the grinding wheel 66. The grinding wheel 66 is locally cooled by more reliably contacting the coolant with the grinding wheel 66 by teating off air from above the grinding wheel 66 after arranging the work member just before the coolant flowing area.
