IPC: F02D45/00
Filed: 1979-11-01
Abstract: PURPOSE: To increase the responsiveness in a simple structure by specifying the methods for forming and outputting the knocking identification signal.  
     CONSTITUTION: The knocking sensor 1 which is connected to an ignition time control part 2 is constituted by a vibration sensor 11, a sensor processing circuit 100, a smoothing circuit 200, a comparating circuit 300, an integrating circuit 400, a knocking identification circuit 500, and a reset circuit 600. The signal in the knocking frequency region from the vibration sensor 11, which converts the vibrating components of noises, pressure, and the like of the engine into the electric signal, is compared with the smooth level signal which is obtained by rectifying and smoothing the signal from the vibration sensor 11. The compared output signal are integrated. The integrated signal is compared with the reference level and the knocking identification signal is outputted. At every specified crank angle and at every time the knocking identification signal is outputted, the integrated signal is reset, and the knocking identification signal is further outputted at a frequency corresponding to the knocking strength.

Title: Warm-airspace heater
Inventor: YAMAZAKI TADASHI
IPC: F24H3/04
Filed: 1988-06-08
Abstract: PURPOSE:To ensure that a flow of hot air comes into contact with a floor surface at some distance from a hot air blow-off port and prevent the temperature of the floor surface from being abnormally raised to cause discoloration of the floor surface by providing a substantially horizontal guide piece at a lower part of the hot air blow-off port. CONSTITUTION:A substantially horizontal guide piece 16 is attached to a lower edge of a blow-off port frame opening 15, and a variable vane 18 provided at a blow-off port frame 14 so as to be located at an upper part of a hot air blow-off port 3 is made to be so wide as to cover nearly the upper half of the frame 14. When the variable vane 18 is set substantially vertical, a flow of hot air does not come into contact with a floor surface immediately upon being blown off from the port 3 but is guided by the guide piece 16 to come into contact with the floor surface at some distance from the port 3, as indicated by an arrow (a). At the time of the contact, the temperature of the hot air is already lowered to a certain extent by the mixing of the hot air with room air, so that the floor surface is maintained at a comparatively low temperature.

Title: Camera provided with solar battery
Inventor: SUZUKI RYOICHI
IPC: H02J7/35
Filed: 1993-05-21
Abstract: PURPOSE:To reduce futile power consumption by detecting the charging operation from a solar battery to a secondary battery and supplying power to an overcharge prevention circuit for preventing an operation of overcharging the secondary battery only when the charging operation is carried out. CONSTITUTION:Only when the charging operation from the solar battery 1 to the secondary battery 3 is carried out, a reverse current preventing diode 2 is forward-biased, so that a PNP transistor for detecting the charging operation 4 is turned on, and then, the power is supplied to a comparator 6 and a reference voltage generation circuit 7. In the case that the voltage charged to the secondary battery 3 is low, the voltage divided by resistances 8 and 9 is lower than the output voltage of the reference voltage generation circuit 7, so that the output of the comparator 6 is kept at a low level and a MOS-FET 34 is kept in an off-state. On the other hand, when the charging operation is proceeded from the solar battery 1 to the secondary battery 3, the distributing voltages of the resistances 8 and 9 become higher than the output level of the reference voltage generation circuit 7 due to the boosting of the charging voltage of the secondary battery 3, then, the MOS-FET 34 is turned on so as to prevent the secondary battery 3 from being overcharged.

Abstract: PURPOSE:To make it possible to blow mold a parison without developing flash by quickly inserting the parison in a cavity under the condition that the temperature of the parison is prevented from lowering by a method wherein a pair of split mold main parts of split molds are drawn near with a gap, which is the specified times as large as the diameter of the parison, and, after that, the parison is inserted by lowering it along a cavity and finally the molds are closed so as to blow mold the parison by forcing pressurized fluid in the parison. CONSTITUTION:In a pair of split molds 1 consisting of split mold main parts 5 and split mold upper parts 8 and split mold lower parts 10, both of which are just on the upper parts and the lower parts of the split mold main parts 5, a pair of split mold main parts 5 of the split molds 1 are drawn near with a gap (l), which is about 1-1/3 times the diameter of a parison 13. Under the state as just mentioned above, the parison 13 is inserted in a cavity 4 from the upper end opening of the cavity 4 by lowering it along the inner surface of the cavity 4. After the split mold main parts 5, the split mold upper parts 8 and the split mold lower parts 10 are closed each other, pressurized fluid is forced in the parison 13 in order to blow mold it. If the gap (l) for inserting the parison is too large, the parison 13 is off the cavity. If the gap (l) is too small, no effect of the gap develops. The preferable gap is about 1-1/3 times the diameter of the parison 13 or about 15mm ordinarily in the case for molding, for example, the duct for automotive air conditioner.
