Title: Travel controller for train
Inventor: KAWANA MASUO
IPC: B60L15/40
Filed: 1981-11-10
Abstract: PURPOSE:To enable free organizatin of trains by providing a function for discriminating whether it is a preceding train or a following train at each train, controlling it at a constant speed at the preceding train and controlling the interval of the prescribed trains at the following train. CONSTITUTION:A train distance measuring device 3 provided at the front of each vehicle transmits supersonic wave of frequency f1 toward the front. A train distance measuring device 5 provided at the rear transmits supersonic wave of frequency f2 when it receives the supersonic wave of the frequency f1. A main controller 4 judges as the preceding train when the supersonic wave of the frequency f2 is not received even if the prescribed period of time is elapsed by the device 3, thereby controlling the train at the constant speed. When the supersonic wave of the frequency f2 is received, it judges as the following train, thereby controlling the train so that the distance between the train and the preceding train is constant.

Title: Insulation-resistance measuring method, wherein fluctuation in circuit constant is compensated
Inventor: MATSUNO TATSUJI
IPC: G01R27/18
Filed: 1987-07-21
Abstract: PURPOSE:To measure the insulation resistance of an electric path accurately, by always correcting deviations in amplitude and phase with an amplitude correcting circuit and a phase control circuit. CONSTITUTION:A piece of conductor 20, to which a switch SW is connected, is inserted in a current transformer ZCT. The switch SW is opened and closed with a signal having a repeating frequency fs from a phase control circuit PC1. A current, whose phase is shifted by 90 deg. from a low frequency signal voltage for measurement having a frequency f1, is made to flow through the conductor 20. The voltage is outputted to a winding N2 of a transformer OT. Meanwhile, the output of the current transformer ZCT is made to pass through a filter FIL. The commercial frequency component is removed. The output is supplied to an adder ADD12 and an amplitude correcting circuit 30. The output through the circuit 30 is supplied to one terminal of the adder ADD12. The signal is corrected with the circuit 30 so that the amplitudes of both components of the frequencies f1-f2 and f1+f2 included in the output of the filter FIL become equal. The corrected current is inputted into a synchronous detector MULT1. A signal voltage having a frequency f1 from the circuit PC1 is inputted into one input end. Synchronous detection is performed. The phase of the signal voltage having the frequency f1 is automatically adjusted so that the component of the frequency fs in the output of the synchronous detection becomes zero. Thus the insulation resistance can be accurately measured.

Title: Medium carrying device
Inventor: FUJISAWA KOICHI
IPC: G03B27/32
Filed: 1990-07-09
Abstract: PURPOSE:To make cost reduction of the device possible by rationalizing the structure of the device by a method wherein when a single motor rotates normally, nip rolls which have been in contact with a main drum separate from the main drum by the rotation of an eccentric cam, and when the motor rotates reversely, a cutter is driven, and a medium is cut. CONSTITUTION:When a rotary shaft 26 rotates counterclockwise by a pulse motor, a disk 24 also rotates in the same direction by a one-way clutch 20. The rotation of the disk 24 shakes a lever 22 to the right through a bar 23, and turns a rotary blade 7b clockwise by turning a shaft 7c. By this motion, a medium 4 which is located between the rotary blade 7b and a fixed blade 7a is pinch-cut. When the pulse motor 21 rotates clockwise, in the reverse direction from when a cutter 7 is driven, an eccentric cam 31 also rotates by a one-way clutch 20', a gear 37 and a gear 33 and pushes a lever 19 to the right. The lever 19 rotates counterclockwise and pushes nip rolls 9 in the same direction and functions to separate the nip rolls 9 from a main drum 8. At this time, since the one-way clutch 20 gives idling, the cutter 7 is not affected at all.

The wire 3 is made to extend, and the weight 2 reaches a measuring surface. The looseness of the wire 3 caused by the decrease in weight based on the buoyancy is absorbed with the recovering force of the spring 6. Required tension is imparted to the wire. Even when the weight 2 reaches the measuring surface, the weight applied on the wire by the buoyance is decreased and the looseness is generated in the wire, the spring absorbs the looseness. The distance to the measuring surface can be accurately read based on the feeding amount of the wire.
