Title: Breakwater
Inventor: MORITA TOMOSHI
IPC: F03B13/12
Filed: 1991-02-12
Abstract: PURPOSE:To expand a sea area for breakwater application, improve water breaking capability and effectively utilize wave energy by arranging a pair of front and aft buoyant breakwater bodies so placed on support piles on the sea bottom as to be capable of free oscillation, and connecting the upper ends of the bodies to each other with a rod. CONSTITUTION:A pair of buoyant breakwaters 2 and 3 are laid at the predetermined intervals L in the front and aft direction for a wave progress direction X. Also, support arms 7 fixed to the lower ends of respective breakwaters 2 and 3 are so placed on support piles 8 and 10 as to be freely rotatable via hinges 9. Respective upper ends 26 of the breakwaters 2 and 3 are connected to each other with a rod 11. According to this construction, a horizontal force due to wave energy causes the oscillation of the breakwaters 2 and 3, and the resonance thereof dampens the wave energy to dissipate waves. Also, the connection rod 11 offsets a horizontal force acting on the breakwaters 2 and 3, thereby restraining the oscillation of the breakwaters 2 and 3. In this case, the rod 11 may be interrupted, and an energy converter may be fitted between the broken rods, thereby providing a structure for converting wave energy.

Title: Seat for vehicle
Inventor: KIUCHI TORU
IPC: B60N2/06
Filed: 1993-03-02
Abstract: PURPOSE:To keep constant the tensile strength of a cable used to transmit the motive power from a motive power generating means to a lift up means constant constantly, and to operate the lift up operation without a response delay, whereever the seat may be moved. CONSTITUTION:When a seat is moved longitudinally, the motive power transmission from a pulley 13 to the lift up means in a seat cushion 10 is cut off by a motive power circuit cutoff means 18 in the seat cushion 10, according to the operation of a seat slide lever 19. Since the seat is moved in such a condition, the pulley 13 runs idle while winding a cable 12, and moves together with the seat. Consequently, the tensile strength of the cable 12 is maintained constant even when the seat is moved.

Title: Rotary encoder
Inventor: KURODA MASASHI
IPC: G01D5/245
Filed: 1990-02-23
Abstract: PURPOSE:To make an encoder compact by arranging arc shaped patterns of leading phase contact points and delaying phase contact points on the same circumference of a code plate where signal leading-out terminals are provided, and providing a plurality of sliding contact points for sliding the patterns of the leading-phase and delaying-phase conduct points on a rotary shaft. CONSTITUTION:A ring shaped common signal pattern 2 is provided in the inside of a code plate 1. A pattern 3 for a leading-phase signal 3 and a pattern 4 for a delaying- phase signal on the two parts which are obtained by dividing the circumference are provided in the code plate 1. The patterns 2 - 4 are connected to terminals 12 - 14 for leading out the signals. Sliding contact points 5a and 5b are further attached to a rotor 7 which is rotated together with a rotary shaft 6 as a unitary body. The contact points 5a and 5b are located at the symmetrical positions with respect to the rotary shaft 6. Therefore, when the contact points 5a is located at the side of the pattern 3, the contact point 5b is located at the side of the pattern 4. When the contact point 5a is located at the side of the pattern 4, the contact point 5b is located at the side of the pattern 3. Therefore, when the rotary shaft 6 is rotated, the contact points 5a and 5b close and open the circuits with the pattern 2 together with patterns 3 and 4. Thus, the electric signals in two phases of the leading phase and the delaying phase are generated.

Title: Buffer type gas-blast circuit breaker
Inventor: SATO TOSHIKAZU
IPC: H01H33/915
Filed: 1990-02-23
Abstract: PURPOSE:To enhance a breaking characteristic by supplying gas in a first buffer chamber into a second buffer chamber through a space between a stationary contact and a movable contact and a passing hole at the initial of a breaking operation, and shielding the passing hole of a partition plate by means of a projection of a buffer piston at the final of the operation so as to spray the compressed gas in the first buffer chamber to a space between the stationary and movable contacts. CONSTITUTION:In case where an advance small current is cut when a stationary arc contact 1 is brought into contact with a movable arc contact 5, the current can be cut despite of a short arc time since the current is small even if a movable contact unit 2 is moved with application of an opening command. After that, a buffer cylinder 4 is moved to compress gas at a speed relative to a movable partition plate 10, and consequently, gas in a first buffer chamber 9a is supplied into a second buffer chamber 9b through a space between the contacts 1 and 5 and a gas passing hole 11. The partition plate 10 is moved toward a buffer piston 8 by the effect of the compressed gas. With further movement, the partition plate 10 reaches a projection 8a of a piston 8 to shield the hole 11, and then, gas in a chamber 3a is compressed by the partition plate 10, to be thus sprayed between the contacts 1 and 2.

Title: Refrigerating system
Inventor: UEHARA SHINPACHIROU
IPC: F25B1/00
Filed: 1978-04-07
Abstract: PURPOSE: To maintain the stability of condensing pressure with the normal amount of refrigerant by connecting the first condenser provided with a fan controlled by a high pressure switch in parallel with the second condenser provided with an electromagnetic valve and a fan controlled by a thermo-switch of open air temperature.  
     CONSTITUTION: When an open air temperature is comparatively high, a condensing-pressure regulating valve 15 works little, and the refrigerant gas discharged from a refrigerant compressor 1 is branched to be introduced into the first and the second condenser 9 and 14, and conducted through a liquid pool 3 and an expansion valve 4 to be evaporated in an evaporator 5 for cooling. When the open air temperature is lowered, however, the discharge pressure is lowered below the set pressure in the condensing-pressure regulating valve 15, and by the operation of the regulating valve 15, the discharged gas is conducted through a bypass circuit 16 into the regulating valve 15. Consequently, liquid refrigerant is collected in the first and the second condenser 9 and 14, and the condensing pressure is raised to return to a fixed set point. This construction serves to maintain the condensing pressure in a constant level without being influenced by the variation of the open air temperature.

IPC: G04G5/00
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To detect a time signal again even if it is not detected once thereby correcting the time by changing the start-up time of broadcasting wave reception means when the signal is not detected. SOLUTION: A broadcasting wave reception means 14 selects a signal of frequency corresponding to a time signal and detects the signal from the reception signals relating to the broadcasting wave received. A system controller 16 controls the start-up of a tuner 14a of the means 14 as well as the correction of time of a timer 12. Namely, the controller 16 corrects the time of the timer 12 corresponding to the time signal detected by the means 14 and also starts the means 14 at the time with a specified margin of time according to the time of timer 13. However, when the time signal is not detected because the time of the timer 12 is deviated from the specified margin of time caused by some reasons, the margin is gradually increased. Then, the time is corrected after the time signal is detected and the margin is reset to the original level.
