Title: Recording medium reproducing device
Inventor: YOSHIMURA MASAKI
IPC: G11B17/22
Filed: 1995-04-27
Abstract: PURPOSE: To make a recording media housed in the housing section of a recording medium reproducing device provided with a recording medium exchanging device to be replaced with another medium in arbitrary order in the housing section without taking out the media to the outside. CONSTITUTION: A stocker 21 can house disks and a reproducing means reproduces information from a disk. A first transferring means 31 transfers disks between the inside of the stocker 21 and the outside of a recording medium reproducing device and second transferring means transfers disks between the inside of the stocker 21 and a reproducing position. Since the stocker 21 can be moved in the vertical direction, the height of the first or second transferring means can be flushed with the height of an arbitrary disk in the stocker 21.  While the first or second transferring means takes out a disk from the housing section of the stocker 21, the stocker 21 is moved and the first or second transferring means is aligned with an empty location which is different from the location from which the transferring means takes out the disk from the housing section, and then, the first or second transfer means houses the disk in the empty location.

Title: Snow fall measuring apparatus
Inventor: KOTAKI RINTARO
IPC: G01W1/14
Filed: 1992-05-20
Abstract: PURPOSE:To obtain a snow fall measuring device which enables measurement of snow fall at a plurality of measuring points with one snow sensor alone. CONSTITUTION:When a measuring point on the surface 10 of snow is P1, a position control section 5 controls sensor drive sections 3 and 4 to set signal transmitters 1 and 2 to corresponding angles theta1 and theta2 so that the transmitters 1 and 2 are turned toward the measuring point P1. Under such a condition, ultrasonic waves transmitted from a signal transmitter 1 are reflected from the measuring point P1 to be received by a signal transmitter 2. A time difference detecting section 6 detects the time difference between transmitting time and receiving time of the ultrasonic wave at this moment and the results are outputted to an arithmetic processing section 8. A signal correction section 7 determines a correction factor corresponding to the angles theta1 and theta2 given from a position control section 5 to be sent to the arithmetic processing section 8, which determines the coverage of snow D from the time difference and the correction factor to be outputted. The same operation as mentioned above is performed pertaining to the measuring points P2 and P3.

Title: Azimuth type recorder and reproducer
Inventor: NOGUCHI TAKAHARU
IPC: G11B5/55
Filed: 1981-08-17
Abstract: PURPOSE:To ensure the recording of high density and at the same time to simplify the circuit constitution, by switching the gap direction of a magnetic head every time when a magnetic tape having different directions of magnetization between the contiguous recording tracks travels in a prescribed direction. CONSTITUTION:A magnetic head 1 containing head gaps 21-23 is held by a holder 15. The holder 15 is set turnably by a stepping motor 17 via a speed converter 16. The motor 17 turns the head 1 toward an arrow (a) by theta1 and toward an arrow (b) by theta2 respectively by a controller 18 of turning direction. A magnetic tape 4 reverses its upper and lower surfaces between the forward travelling (arrow A) and the backward travelling (arrow B). When the tape 4 travels toward the arrow A, the head 1 turns toward (a) to perform the recording on the forward recording tracks 51-53. While the backward recording tracks 61-63 are recorded when the tape 4 travels toward B. As a result, the recording density is increased. At the same time, the head 1 is used for the recording and reproduction in common with both forward and backward travels of the tape 4. This simplifies the circuit constitution.

Title: Measurement of frequency characteristics of optical fiber cable

IPC: G01M11/02
Filed: 1977-10-25
Abstract: PURPOSE: To measure the frequency characteristics without the use of local oscillatory signals by transmitting two optical intensity modulated lights of constant modulated frequency difference.  
     CONSTITUTION: The modulated signals of frequency f, which are generated by a signal generator 1, are subjected to frequency conversion by a frequency converter 5 so that the modulated signal frequency f is varied to generate modulated signals of frequency f+Δf having the difference Δf always constant. The two modulated lights from light sources 3 and 6, which have their intensities modulated in accordance with those two modulated signals, enter an optical fiber 10 through their respective beam splitters so that the emanating lights are converted into electric signls by an optical detector 11. The resultant photocurrent is squarely detected by a mixer 13 so that only the fundamental frequency component is detected by a narrow band filter 14 having a passable center frequency of f and a band width less than 2Δf. As a result, the local oscillatory signals for synchronous detection can be dispensed with. As a result, the measurement of the frequency characteristics can be accomplished easily and reliably without providing any coaxial cable for transmission of the local oscillatory signals
