Title: Hot air heater
Inventor: MIURA HIROFUMI
IPC: F24H3/04
Filed: 1987-03-31
Abstract: PURPOSE:To improve the service life of a thermostat by employing a positive characteristic heater generating element which show an increasing resistance as its temperature rises, and causing power for driving a fan motor to be supplied through the contact point of the thermostat. CONSTITUTION:When the power source switch S1 is closed, a heater HT is energized to start heating, and a fan motor FM is rotated to supply air that has been heated by the heater HT to heat an object to be heated. When the temperature of the object to be heated reaches the predetermined temperature, the contact point of a thermostat TS opens to stop the fan motor FM and the air supply to the object to be heated. Although the surface temperature of the heater HT tends to further rise, the resistance level rapidly increases above the predetermined temperature so that the temperature of heater HT is maintained nearly constant. When the temperature of the object to be heated presently becomes lower than the predetermined temperature, the contact point of the thermostat TH closes to cause the fan motor to be rotated and supply hot air heated by the heater HT to the object to be heated, and the temperature of the object to be heated increases. By repeating such a process, the temperature of the object to be heated is maintained early constant.

Abstract: PURPOSE:To prevent abnormal advance in crank angle and prevent knocking surely by providing a pressure sensor which detects pressure inside an intake port to compare the output voltage of said sensor with the specified value and delaying the ignition timing when said output voltage exceeds the usual constant voltage. CONSTITUTION:The output of a pressure sensor 1 which detects pressure inside an intake port of an internal combustion engine is sent to a function voltage generating part 2 to generate the specified function voltage therein.

Abstract: PURPOSE:To surely prevent an automobile from being stolen, by providing switches, etc. for sensing respectively the locked and release positions of a handle provided with a key cylinder in a remote control section so that an alarm is issued for a predetermined time when a hood is opened in such a condition that an ignition switch is locked. CONSTITUTION:When an ignition switch G in a remote control section A is turned to its lock position, a movable piece in a change-over switch S2 makes into contact with a terminal X therein, and therefore, a voltage is applied to the anode of a silicon control element SCR. In this condition, when a hood E is opened, a switch S1 for detecting the opening of the hood E is turned on, and the SCR is energized by a voltage which is obtained by dividing a potential through resistors R1, R2. Simultaneously, a base voltage is applied to the base of a transistor T2 which is therefore energized to allow a buzzar B to issue an alarm. At this time even if the hood is closed and the switch S1 is turned off, the energization of the SCR may be maintained.
