Title: Method of building footpath between rice fields
Inventor: UNO SHINICHI
IPC: A01G22/22
Filed: 1984-04-27
Abstract: PURPOSE:To build a new footpath between rice fields through a simple work, and to prevent grow of weeds on the footpath between rice fields and the occurrence of water leak, by a method wherein a soil coagulant is mixed as an old footpath between rice fields is collapsed, and when a new footpath between rice fields is built, impact, simultaneously, is exerted. CONSTITUTION:A tractor 1 is caused to run in a condition to stranddle an old footpath 35 between rice fields, and after a trench is digged in the central part of the oil footpath 34 deeper than the surface of a field by means of a trencher 19, the old footpath 35 is collapsed by means of a rotary claw 20. In which case, a soil coagulant 29 is mixed in footpath soil, and simultaneously, the soil is prevented from escaping through sides by means of a side cover 23. The soil is shaped by a front shaping cover 24 to build a new footpath 39 between rice fields, impact is exerted on the new footpath 39 by means of a vertically vibrating roller 21, and is shaped by a rear shaping cover 25 to build the new footpath 39. A soil coagulant is mixed in the oil footpath and impact is exerted on the new footpath, and this enables building of the new footpath 39 through a simple work, and prevents grow of weeds and leakage of water.

Title: Magnetic ink recorder
Inventor: DAITOU CHIAKI
IPC: G03G19/00
Filed: 1982-05-21
Abstract: PURPOSE:To enable a high quality printing by electrically controlling variation in the tip meniscus radius of a recording electrode due to temperature. CONSTITUTION:The temperature of magnetic ink 8 detected with a thermocouple 6 is adjusted properly depending on the temperature of the recording section. When it is high, a pulse voltage with a large width is applied to an auxiliary electrode 19 to lower the viscosity of ink with a rise in the temperature so that the amount of the magnetic ink 8 will be increased to make a proper meniscus radius. When it is low, the pulse width of the pulse voltage is reduced to lessen force working on the magnetic ink 8 between the auxiliary electrode 19 and an opposed electrode 2 so that the amount of the magnetic ink will be decreased to trim excessive meniscus radius. This enables electric control of changes in the tip meniscus radius of a recording electrode 1 depending on the temperature thereby assuring a stable control without mechanically oscillatory section.

Title: Liquid constitution of heat pipe operating liquid
Inventor: ITAGAKI TAKESHI
IPC: G01N31/22
Filed: 1983-05-18
Abstract: PURPOSE:To facilitate the gas leakage inspection in a heat pipe of solar heat collector etc. by adding an organic chemical compound of halogen family having a similar boiling point to the heat pipe operating liquid consisting of an organic compound of non-halogen family. CONSTITUTION:In a case where acetone which is an organic compound of non- halogen family is used for heat pipe operating liquid for example, an organic compound of halogen family such as 1, 2 dichloro-1,2-diphloroethane, 1,2-dichloroethane-dichlorohexafluorobuthane is added to the former by 20wt% as a gas leakage detecting additive. In this manner, if the sealing of the heat pipe is not adequate, the gas leakage can be checked out by bringing a halogen gas detector closer to the sealed part. As the additive works as a heat pipe operating liquid, the efficiency will not be greatly reduced in comparison with one which consists solely of acetone.

IPC: H04N9/86
Filed: 1980-06-26
Abstract: PURPOSE:To achieve high-density and skew-distortion-free special reproduction on a PAL and a SECAM system by delaying successively and recording a color signal on a magnetic tape with a specific time difference different in every constant period. CONSTITUTION:A luminance signal, after passing through an LPF2, is modulated by a frequency modulator 4 and the modulated signal is added to a color signal by an adder 6. An output chrominance carrier signal from a BPF3, on the other hand, is led to terminals (a)-(d) of a switch circuit 17 via 0.5H-1.5H delay lines. Connections of the circuit 17 are changed by frequency division outputs 24 and 25 of a head changeover signal 23. The output of the switch 17 is supplied to the adder 6 via a frequency converter 5 and adders 18 and 19. Then, color signals of alternate tracks are recorded on the magnetic tape in order. In reproduction, on the other hand, output signals are obtained by being delayed successively with time differences inverse of those in recording. For special reproduction, discontinuous points of a reproduced horizontal synchronizing signal are detected, and the delay times are changed by control signals obtained from the detection signals.

Abstract: PURPOSE:To decrease the burden of a living body due to pressing of a pulse wave sensor by providing a means for setting the pressing force of a pulse wave sensor lower by a prescribed value than the optimum pressing force and maintaining the sensor at the lowered pressing force during the stabilization of a blood pressure. CONSTITUTION:The blood pressure value is continuously determined by a blood pressure value determining means in accordance with the pressure pulse waves successively detected by the pulse wave sensor maintained at the optimum pressing force by a pressing force regulating means. The pressing force of the pulse wave sensor is set lower by the prescribed value than the optimum pressing force and is maintained at this pressure in such a manner that the actual peak intervals are maintained within a prescribed value of the peak intervals at the time of the stabilization by a second pressing force adjusting means, when the blood pressure value at the optimum pressing force is decided to be stable by a blood pressure value stabilization deciding means. Whether the change in the blood pressure value takes places or not is decided according to whether the peak intervals are maintained within the prescribed range or not by a blood pressure value change deciding means. As a result, the pressing force of the pulse wave sensor is lowered and the blood pressure value is adequately monitored when the blood pressure value is stabilized.
