Title: Material distribution label
Inventor: YAMAGOU MASANAGA
IPC: B42D15/00
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To provide a material distribution label which has a pseudo adhesive structure, does not require release paper, and is easily affixable to any distributing articles with simple operation by adopting a thermosensitive tacky adhesive layer as the tacky adhesive layer of the material distribution label structured to have a release layer between a cover and the tacky adhesive layer. SOLUTION: This label is formed by disposing the release layer 3 between the cover 1 to be stated with material quantity information on the front surface and the tacky adhesive layer 2 consisting of the thermosensitive tacky adhesive. While the release paper 3 is securely adhered to the tacky adhesive layer 2, the release paper is peelably adhered (pseudo adhesion) to the cover 1. Since the tacky adhesive layer 2 is composed of the thermosensitive tacky adhesive, the layer has not tacky adhesiveness and does not require the release paper at the time of nonuse. The tacky adhesive layer exhibits the tacky adhesiveness by the simple operation of heating the label to the activation temp. or above.  Even more, the layer maintains the tacky adhesiveness for a while even if the label is cooled to ordinary temp. after once heating and, therefore, the easy sticking to any distribution articles is possible.

IPC: F16F13/28
Filed: 1993-02-15
Abstract: PURPOSE:To perform an effective vibro-absorption conformed to vibration frequency as well as to enable it to perform this vibro-absorption extending over a wide range of frequencies by making a liquid ply between a main liquid chamber and a sub-liquid chamber through first, second and third limiting passages different in passing resistance each, according to the vibration frequency. CONSTITUTION:In cases where there is idling time and car speed is 5 km or so, vibration in a relatively high frequency band among low frequencies is produced. A control means 46 judges whether the vibration generated at present is an idling one or not by a car speed sensor 43 and an engine speed sensor 45. When it is so judged that an idling vibration is generated, a motor 48 is controlled so as to make a rotor 52 into a state of being interconnected to a passage 32 by a through hole 54 and to arrive at a position where a passage 36 comes to an unconnected state by an outer circumferential surface of the rotor 52. In consequence, the liquid plies between a main liquid chamber 28 and a sub-liquid chamber 30 through the passage 32, and thereby a liquid column resonates in this passage 32 so that the idling vibration is absorbed in this way.

Filed: 1980-02-29
Abstract: PURPOSE: To conduct an appropriate operation control necessary for comfortable sleep at sleeping time by regulating the control temperature of a temperature adjustor stepwise with an operating signal of the temperature adjustor as an input.  
     CONSTITUTION: The deviation of an output of a room-temperature sensor 2 from a setpoint selected by operating a variable resistance 3 is detected by a bridge 7, and a relay 13 is energized by a comparator 10 to start a cooler. When the voltage at an output point 201 is high and at the moment when the temperature adjustor 1 generates a signal for stopping the cooler as a result of a reduction in the room temperature, a counter 22 in a regulator 16 conducts the first run of counting, a capacitor 19 is discharged through a resistance 18 and the voltage at an input terminal C of the counter 22 is lowered to generate a lower voltage at an output terminal Q1. Consequently, a transistor 23 is turned ON, the voltage at an output point 72 is raised and the control temperature of the adjustor 1 is raised. When the room temperature exceeds the control temperature, a cooling operation is restarted and the voltage at the output point 201 is raised to charge the capacitor 19. When the room temperature is lowered and a stopping signal is generated, the above operations are repeated to generate an output from a terminal Q2, thereby further raising the control temperature.
