Abstract: PURPOSE:To improve reliability by utilizing the change in an output signal which is outputted from a temperature detecting terminal on the basis of the difference of temperature characteristics between a 1st and a 2nd detecting elements and obtaining a detected temperature as the boundary temperature of the 2nd detecting element. CONSTITUTION:A PTC thermistor 4 has the positive temperature characteristic in a fixed temperature range. And a V type thermistor 6, where a specified temperature To in the fixed temperature range is regarded as the boundary, has the positive temperature characteristic on a high temperature side corresponding to the thermistor 4, and has the negative temperature characteristic on the side where the temperature is lower than the temperature To. Such a temperature detector 1 is arranged, for example, near the heat generating part of an air conditioning equipment and a prescribed voltage Vcc is supplied between lead wires 7a and 7b. In the temperature range where the temperature of the thermistor 4 or 6 is higher than the temperature To, the ratio between the impedance of the thermistor 6 and the whole impedance of the thermistor 4 or 6 is always fixed. Contrarily, in the temperature range where the temperature of the thermistor 4 or 6 is lower than the temperature To, the ratio is rapidly increased on the basis of the negative temperature characteristic of the thermistor 6. Thus, the temperature control for the air conditioning equipment can be performed by detecting the output signal V01.

Title: Method of controlling ignition timing and its apparatus
Inventor: SAWADA DAISAKU
IPC: F02P5/153
Filed: 1978-05-10
Abstract: PURPOSE:By digitally operating the difference of frequencies generated between the standard pulse and the pulse output from a knock detecting device, to control statical ignition timing in response to the dispersion of knocks. CONSTITUTION:The ignition pulse generated in a pickup 2 with the rotation of an engine is converted into a square wave by a wave form shaping circuit 3. On the other hand, the signal detected by a knocking sensor 9 is transmitted to a knocking discriminant circuit 11 through a filter 10 and outputs one pulse every ignition cycle where knocks occur. The integrating circuit 6 receiving ignition pulses repeats its integration and outputs square wave pulses whenever a fixed number of pulses is integrated. A counter 7 is counted down by the standard pulses recived from the integrating circuit and counted up by the pulses from the knocking discriminant circuit. In response to these count values the ignition pulses are delayed.
