Title: Apparatus and method for releasing material of gas phase in atmosphere
Inventor: JIYON UORUTAA TAAKO
IPC: A01M1/20
Filed: 1988-09-16
Abstract: PURPOSE: To prolong the life of an apparatus by sorptively saturating a sorbent material with a preset amt. of gaseous material under a preset pressure, selectively bringing the sorbent material into selective contact with the atmosphere, releasing the gaseous material from sorption and releasing the material into the atmosphere. CONSTITUTION: When an apex 14 is removed from a base part 12, openings 18 are formed and the atm. air flows into an air freshener 10 where the air comes into contact with the sorbent material 22. The sorbent material 22 is sorptively saturated with the preset amt. of the gaseous material under the preset pressure. Since the vapor pressure of the gaseous material to be released is low, a small amt. of the gaseous material is released into the atmosphere. The sorbent material has a high storage capacity and the life of the air freshener 10 is thus prolonged.

Title: Greens-planting work for slope
Inventor: SUGIMURA YORIO
IPC: E02D17/20
Filed: 1982-12-28
Abstract: PURPOSE:To promote the growth of plants as well as to prevent the landslide of the ground by strongly fixing the ground of a slope by a method in which a cement mortar layer containing a water absorptive polymer and a soil stabilizer is formed on a slope, and a sludgy greens-planting material is sprayed onto the cement mortar layer. CONSTITUTION:A metal netting is laid on a slope 3 by anchor pins 5, and a cement mortar mixture mixed with a water absorptive polymer (e.g., bridged polyacrylates) and a soil stabilizer is sprayed onto the metal netting to form a sprayed layer 2. Afterwards, a sludgy greens-planting material formed by mixing bark compost, peat moss, compound fertilizer, a water absorptive polymer (bridged polyacrylates), and seeds, together with water, is sprayed onto the cement mortar layer 2. An observation of the growth degree of roots into the cement mortar layer 2 three months after execution proved that the roots of plant had intruded into the cement mortary layer 2 and some of them had penetrated through the layer 2.

Title: Perpendicular contour emphasis suppressing circuit
Inventor: MISAWA TAKASHI
IPC: H04N9/68
Filed: 1988-09-19
Abstract: PURPOSE:To reduce black trimming by supressing an adding processing when a part where the level of a signal R-Y derived from a video signal is relatively high is detected. CONSTITUTION:A voltage EA is impressed to one edge of a variable divided resistance R1, and a voltage EI is impressed to the other edged (EA>EI). A control voltage VAPL indicates a voltage E (EI<E<=EA) on a part where an output signal Vr-(R-Y) of a differential amplifying circuit 31 is positive, and on a negative part, that is, on a part where the level of an R signal is more than a certain extent (on a screen, the part where red or a color similar to it is displayed), the signal indicates a voltage EI. Since the control signal VAPL is applied to a differential amplifying circuit 21 of a contour emphasizing circuit 20, and its amplification factor is emphasized, the contour emphasis is executed only on the part where the differential signal Vr-(R-Y) is positive, and on the part to indicate the negative level, the contour emphasis is not executed. Thus, the contour emphasis is suppressed on the part where the red is displayed on the screen, and the black trimming is decreased.

Title: Color adjusting device for digital picture
Inventor: NISHIMURA TORU
IPC: H04N1/46
Filed: 1988-09-19
Abstract: PURPOSE:To reproduce a digital picture without the generation of color blurring and a pseudo contour by executing color regulation with changing the coefficient of a gradation correcting characteristic. CONSTITUTION:An operator judges the reproduced condition of color by observing a picture outputted to a picture output device 40, when a desired hue is not reproduced, he inputs an instruction concerning the color regulation by operating an operating part 42. For example, when the reproduced picture is too dark as a whole, he inputs the instruction to correct the picture to the light gradation represented by the characteristic such as a gradation correcting characteristic 90. When the picture is too light as a whole, he inputs the instruction to correct the picture to the dark gradation represented by the characteristic such as a gradation correcting characteristic 92. Thus, when the color regulation is executed for the digital picture, the color regulating device of the digital picture without the color blurring and the pseudo contour can be obtained.
Patent JP-H0395421-A (JP)
Title: Weight detector
Inventor: OCHI KENZO
IPC: G01G23/37
Filed: 1989-09-07
Abstract: PURPOSE:To make it possible to obtain an exact weight value in a shorter time by few data memories by determining the weight value of a substance to be weighed, by averaging it sequentially in a time being an integral multiple of the natural frequency period of a weight sensor. CONSTITUTION:Parallel movement metal fittings 4a and 4b fixed to a support 6 transmit accurately to a weight sensor 5 the weight of a substance 2 to be weighed which is set on a saucer 1. When a load is transmitted to a load point 6 by a load transmitting rod 3, a diaphragm 7 is bent and the value of an electrostatic capacity between electrodes 8a and 8b changes. The change in the electrostatic capacity value of the weight sensor 5 is converted into a change in a frequency by a c-f conversion circuit 11. This frequency is counted by a pulse counter 12 and subjected to an arithmetic processing in an arithmetic unit 13 and a weight value is indicated in an indicating unit 14. A gate 15 controls a count time of the counter 12. An impact vibration occurring when the substance 2 to be weighed is set vibrates at the natural frequency of a weight detector. By executing a time average in a time of an integral multiple of the natural frequency period thereof, accordingly, a detected weight value is stabilized in a short time.

Filed: 1988-09-17
Abstract: PURPOSE:To enable the maintenance of a required oil viscosity by separating a working fluid from the oil by a flash evaporation utilizing the low pressure part in the steam motor outlet and the high temperature of a heat source. CONSTITUTION:A working fluid steam formed by the heat exchange with a heat source is supplied to a steam motor T to recover heat in the form of a power.

Title: Yaw rate sensor and angular-velocity detecting method
Inventor: IWATA HITOSHI
IPC: G01P3/22
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To simplify the structure and to decrease the cost in comparison with a conventional yaw rate sensor. SOLUTION: A gel holding means is constituted of a circuit board 1, an upper housing 2 and a spacer 4. A pressure sensitive element 5, which is a semiconductor pressure sensor, is fixed to the upper surface side of the central position of the circuit board 1. A gel-state composition 10 is filled between the circuit board 1 and the upper housing 2. When rotating force is applied on a yaw rate sensor 12 at a certain angular velocity, the displacement of the gel is allowed in the direction perpendicular to the thickness direction by the gel holding means. Since the other direction is restricted, the gel is displaced into the allowed direction. That is to say, the gels located at the opposite positions apart by 180 deg. are displaced in the mutually opposite directions.  Negative pressure is generated at a negative-pressure generating part located between the displacing gels, and the negative pressure in correspondence with the above described angular velocity acts on the pressure sensitive element 5. The negative pressure is detected by the pressure sensitive element 5.
