Abstract: PURPOSE:To enable checks about snapping and a short circuit, by improving a switch circuit for selecting a desired damping force, to convert a switch signal into an electric analogue quantity so that only three electric wires are needed for a motor regardless of the number of selectable damping forces. CONSTITUTION:When a changeover switch 1a is connected to an input terminal 32b, a contact signal is changed into a signal of a voltage determined by the ratio of the sum of resistances 31a, 31b to the resultant value of resistances 33b, 31c. The signal of the voltage is applied to a signal comparison circuit 3, which also receives an analogue signal corresponding to the present position of driving oil 4a. The circuit 3 compares both the signals with each other. If the circuit 3 is sending out an uncoincidentness signal, a driving current is supplied from a motor driving circuit 5 to a motor 4 until the compared signals coincide with each other. At that time, an adjuster provided for a hydraulic buffer T is turned to obtain a desired damping force. According to this constitution, only three electric wires for power supply, common terminal and control signal, respectively, are needed regardless of the number of selectable damping forces.

Title: Wide angle directivity plane antenna
Inventor: YAMAKAWA YOSHIYUKI
IPC: H01Q1/48
Filed: 1991-07-05
Abstract: PURPOSE:To attain an excellent gain in the vicinity of the horizontal direction and to realize the small sized plane antenna by curving the circumferential ridge of a 2nd conductor layer in a direction parted from a 1st conductor layer. CONSTITUTION:The peripheral ridge of a 2nd conductor layer 3 is curved in a direction parted from a 1st conductor layer 1 in the plane antenna in which a dielectric layer 2 is formed between the 1st conductor layer 1 and the 2nd conductor layer 3 to prevent any corner from being formed. Thus, a phenomenon called in general 'fringing effect', that is, a phenomenon that the distribution of an electric field is concentrated onto the peripheral ridge of the antenna hardly takes place. Thus, since disturbance in the electric field at the peripheral ridge of the antenna is less, the reduction in the gain in the vicinity of the horizontal direction is improved. Thus, the excellent plane antenna in which the disturbance is less, a large gain is obtained even in the vicinity of the horizontal direction and the gain is obtained over a wide angle.

Filed: 1983-11-07
Abstract: PURPOSE:To simplify the constitution of a synchronous sound recorder by connecting a synchro switch to the function switch of a record reproducing device in series, and controlling the driving transistor (TR) of a tape sound recording and reproducing device. CONSTITUTION:When a function switch 2 is closed, the record reproducing device enters a reproduction state through a driving electric motor 12, and when the synchro switch 3 connected to the switch 2 in series is also closed, an LED5 turns on to display a synchro mode. When a start switch 13 is closed in this state, the reproduction of the record reproducing device starts and the driving TR8 is turned on through a control TR6 after the delay time determined by a resistance 10 and a capacitor 11 to perform sound recording by the tape sound recording and reproducing device through its driving electric motor 7. Consequently, the consitution of the synchronous sound recorder is simplified.
