Title: Measuring device for tidal current
Inventor: TAKAHASHI HIDEYUKI
IPC: G01S13/86
Filed: 1979-11-20
Abstract: PURPOSE:To measure the tidal current in the vast sea area in a short time by a method wherein a  ground speed is obtained on board a ship by means of a radio distance measuring equipment,  whereas a water speed is obtained from an ultrasonic wave through a wave transmitting and receiving device and both speeds are operated. CONSTITUTION:Radio waves are repeatedly emitted from a radio distance measuring device  master station 1 on board to slave stations 2, 3 on land and the propagation time difference or a  phase difference between them is measured and the location of the master station 1 is obtained. In  this way, a ground speed and the azimuth can be known by knowing the change of position of the  ship in a short time. Whereas, an ultrasonic pulse wave is emitted into the sea water through a  wave transmitting and receiving device 5 which has an azimuth difference of 90 deg. to a water speed  measuring device 4 to obtain the water speed by uuilizing a reflection of micro particles in the sea  water, and at the same time, the azimuth of the ship is measured by means of a direction finding  device 8. The water speed of the ship is a sum of a ground speed and a current speed of a tidal current, on this account, the flow speed of the tidal current can be obtained from performing a  vector operation of both speeds through an arithmetic circuit 6. With this constitution, measurement of the tidal current can be performed in the vast sea area in a short time.

Title: Both-way rotation driving apparatus
Inventor: SEKIGUCHI HARUO
IPC: F25B9/00
Filed: 1977-12-16
Abstract: PURPOSE: In a both-way rotation driving system for a piston to be used to expand the working gas for a cooler, to operate the an exhaust hole through the reciprocation of said piston in which a pair of orthogonally-engaging bevel gears and a rotary crank case are used.  
     CONSTITUTION: When a crank shaft 8 makes one rotation, a bevel gear 9 rotates. The bevel gear 12 engaging with said bevel gear 9 is fixed on a case 16. Therefore, a rotary crank case 11 rotates, and this rotation is takenout by a shaft 20 through gears 17 and 18. A piston 3 makes one rotation while reciprocated vertically by a connecting rod 7 and a pin 6. The working gas having flown in through a suction valve 2 when said piston 3 is at the upper dead point is not discharged since an exhaust gas passage 4 passes on exhaust groove 5 absent side when said piston 3 lowers. When said piston 3 rises, however, gas discharge is continuously performed since the open portion of said exhaust passage 4 aligns with said exhaust groove 5.
