Title: Calling control system for radio communication system
Inventor: FUKUI MASASHI
IPC: H04B7/24
Filed: 1978-08-30
Abstract: PURPOSE:To secure a highly efficient communication in an emergency by transmitting the special free line signal which can be received only at the specified terminal station. CONSTITUTION:Special free line signal detector DTb is installed at TS2 which is specified terminal station in order to give the frequency detection to special free line signal fb. Thus signal fb transmitted from master station MS in an emergency is received only at TS2, and reception of fb is impossible for the terminal station TS1 which contains no DTb. In other words, an assured communication is secured to TS2 in an emergency.

Filed: 1987-04-28
Abstract: PURPOSE:To enable the performance of an engine to be sufficiently utilized, by correcting the control amount relating to a combustion condition based on the output of a means which stores a past record of thermal load hysteresis received by the engine. CONSTITUTION:A steady supercharge pressure and steady ignition timing are respectively calculated based on a map, which is previously experimentally determined and stored in a control unit 8, by an intake air amount detection signal detected by an air flow sensor 13, and an engine speed detection signal detected by a distributor 10. Next, a thermal load value is calculated based on the map, which is previously experimentally determined and stored in the control unit 8, and on a read engine cooling water temperature detection signal. On the basis of the above, the steady supercharge pressure and the steady ignition timing are corrected. In this way, since the steady value is corrected by using the thermal load value representing the surface temperature of a combustion chamber reflecting a past record of the thermal load hysteresis, a more accurate control can be attained, and minimizing a surplus control amount, the performance of the engine 1 by can be sufficiently utilized.

Title: High altitude compensator for carburetor
Inventor: NIWA TAKAO
IPC: F02M7/20
Filed: 1978-08-30
Abstract: PURPOSE: To provide a high altitude compensator for a carburetor, with which the richness of air-fuel mixture is made proper through air bleeding, and also which is simple in construction, inexpensive and capable of ready maintenance.  
     CONSTITUTION: In level or low-lying ground, a bellows 21 is in a contracted state, and a port 23 is closed by a valve 22. Thus, in this case no air is bleeded through an air bleeding path 3. In high-lying ground, the bellows 21 is in an elongated state, and the port 23 is open. Thus, in this case atmospheric air is bleeded through the air bleeding path 3. At this time, if the engine is in a high load condition, the negative pressure acting upon a negative pressure port 18 is low. Thus, an opening  8 is opened by a valve body 20 with a diaphragm 13 of a negative pressure change- over valve 5 biased by a spring 19 in the direction of expanding a negative pressure  chamber 14. Thus, air introduced into the path 3 is increased through the opening  8, an orifice 11 and a branch path 4A to an air bleeding port 2 to increase the air  bleed quantity.
