Title: Control circuit for air purifying device for vehicle
Inventor: MATSUSHIRO TADASHI
IPC: B60H3/06
Filed: 1986-11-20
Abstract: PURPOSE:To eliminate unnecessary discharge of a battery, by a method wherein the input of an air purifying device is shut off by detecting opening of a door and thereafter, even if the door is closed, an input is kept in a shut off state until a main switch is made again. CONSTITUTION:When the door of an automobile is opened during turning ON of a motor blower 2, a door switch 13 is closed in an earthing state, the base of a transistor 5 is brought into an earthing state, and the transistor 5 is brought into an OFF-state. In which case, the base current of a transistor 4 is stopped, and a blower 2 is brought into an OFF-state. Even if, after that, a door is closed and the door switch 13 is opened, since no collector output from the transistor 4 is provided, a transistor 5 is not turned ON, and the transistor 4 can not be also turned ON. In which case, with a main switch 3 made once, charge accumulated in a capacitor 11 is discharged through a diode 12 and a resistor 9, and the blower 2 is brought into an ON-state by closing the main switch 3 again. This constitution prevents the power source of an air purifying device from being left closed.

Title: Synthesizer modulation circuit
Inventor: OBA RYOHEI
IPC: H03C3/00
Filed: 1986-11-21
Abstract: PURPOSE:To eliminate the need for an expensive reference oscillator and a frequency adjusting means by using a switch circuit so as to select a reference oscillation frequency generated from a reference oscillation circuit depending on the logic of a digital signal alternatively and supplying the frequency to a phase locked loop circuit. CONSTITUTION:A reference oscillator main body consists of a reference oscillation circuit 51 generating two kinds of reference oscillation frequencies set in advance and a switch circuit 53. The switch circuit 53 is turned on/off in response to the logic level of a digital signal to select the reference oscillation frequency generated from the reference oscillation circuit 51. Thus, the reference oscillator is constituted very inexpensively in comparison with an oscillator using a variable capacitor. Since the reference oscillation frequency is fixed in advance by a circuit constant of the oscillation circuit, it is unchanged depending on the signal level of the digital signal, resulting in obtaining a stable reference oscillation frequency and a circuit varying the signal level of the digital signal is not required.

Title: Fluid controller
Inventor: UPPAL SOHAN LAL
IPC: F04C15/00
Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To eliminate, in a fluid controller, a driving shaft and a pin for transmitting a following motion from a star-shaped member of a hydraulic meter to a valve means. SOLUTION: In response to the relative rotation displacement of a spool 31 and a sleeve 33 due to the rotation input of a steering wheel coupled to a spline 35 of the spool 31, the flow of the fluid in a reservoir R and a vehicle steering device is controlled. The fluid passes a hydraulic meter 15, and lets a star-shaped member 39 perform an orbital rotary motion in a ring member according to the flow of the fluid. Such rotary motion is transmitted to the sleeve 33 owing to the meshing between inner teeth 41 and outer teeth 43 so that the sleeve 33 perform a following motion relative to the spool 31.  Since the rotary motion of the star-shaped member 39 is directly transmitted to the sleeve 33 through the outer teeth 41 and the inner teeth 43, it is possible to eliminate a usual driving shaft and pin, to reduce the diameters of the spool 31 and the sleeve 33, and to assure a simple structure.
