Patent JP-S57120097-A (JP)
Title: Heat exchanger
Inventor: KATSUTA MOTOHEI
IPC: F28F1/40
Filed: 1981-01-20
Abstract: PURPOSE:To reduce the heat transfer area, by arranging a heat exchange pipe having a circular shape in cross section for the heat exchange with a fluid outside the pipe and a thin strip having a width approximately the same as the inner diameter of the pipe. CONSTITUTION:The metal thin strip 7a is uniformly turned by 90 deg. to form a compartment 6a in the pipe 6 of a heat exchanger and is joined to the pipe there with the opposite edges of the strip 7a adjacent to the inner wall surface of the pipe 6. A next compartment 6b is arranged with the end of the metal thin strip 7b normal to the end of the metal thin strip 7a, it being turned by 90 deg. as in the case of the strip 7a to be normal to the metal thin strip 7c of a next compartment. If it is turned more, the resistance will increase, and if the registance is decreased and the turning angle is increased, since the residence time will be prolonged, and a risk such as decomposition at the heat transferring section would occur, the residence time should be as shorter as possible. Thus, the heat transfer area can be reduced, and a decomposable and highly viscous liquid liable to be deteriorated can be subjected to heat exchange.

IPC: B01D53/44
Filed: 1979-01-26
Abstract: PURPOSE: To prevent the deterioration in capturing capacity of an adsorbing agent for evaporated fuel even after use for a long time, by supporting by a specific method the adsorbing agent such as activated carbon filled in a resin vessel so as to prevent the breakage of the activated carbon caused by the vibration of a car.  
     CONSTITUTION: The evaporated fuel from a fuel tank 2 passes through a connecting path 3 and disperses into the activated carbon layer 8, where the fuel is adsorbed by the activated carbon, the residual gas being released through an air opening 6 to the air. Negative press. in a suction line 4 sucks air through the air opening 6, a connecting line 7a so as to permit the air to pass through the activated carbon layer 8, then through a connecting line 5 to the suction line 4. Hereby the air  desorbs the adsorbed fuel while passing along the activated carbon surface, and the fuel is sucked to the suction line 4 and is burned in an internal combustion engine. The capturing apparatus 1 for vapor fuel is attached to a car body, so that the activated carbon particles are liable to be shaken, however because the activated carbon layer 8 is supported by the elastic force of a spring 11 so as to be compressed and filled closely, the activated carbon particles are hardly shaken by the vibration of the car body.

Filed: 1979-01-26
Abstract: PURPOSE: To improve the controllability as well as facilitate the easy selection of the information on the screen by giving the input with the input screen using two sheets of transparent resistance plates put onto the display unit.  
     CONSTITUTION: The transparent resistance layer of indium oxide is formed on the transparent substrate to be used as the resistance plate, and then the electrodes are provided in parallel to the horizontal end at one part and to the vertical end at the other part respectively. Operational amplifier 40 forms the constant current circuit by the negative feedback of feedback resistance R. Operational amplifiers 41 and 42 amplify the voltage applied to micro-resistances r 1  and r 3 , and then delivers the voltage proportional to the voltage flowing to r 1  and r 3  to output terminals 44 and 45. As a result, the voltage proportional to the positional coordinates of contact point P emerges at terminals 44 and 45 each. At the same time, the presence or absence of the contact point is detected via comparator 43, and no current flows when no contact is secured since the area between P and P' is opened. And no voltage is applied to resistance R, and the + terminal features the earth potential. While the current flows to R when the contact is secured, along with the voltage applied to the + terminal. Accordingly, the presence or absence of the contact can be detected by setting threshold voltage VT to a proper level.
