Title: Wave dissipation caisson
Inventor: SHIOZAKI SADAO
IPC: E02B3/06
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To concurrently dissipate normal waves and wake waves by providing a slope inclined upward from the front side toward the rear side of a front transmission wall near the water surface of the front transmission wall. SOLUTION: Normal waves coming from the outside of a harbor are divided into the waves passing through slits 3a and the waves reflected on a transmission wall 3 at the front transmission wall 3. The waves passing through the slits 3a generate vortexes to consume energy at the time of passing and go out to the outside of the harbor after passing through the slits 3a and interfere with the waves reflected on the transmission wall 3 without passing through the slits 3a to negate each other and are suppressed. When wake waves reach the transmission wall 3, the wake waves ascend the slope 3b of the transmission wall 3 and are crushed and dissipated. Normal waves and wake waves largely different in wavelength can be concurrently dissipated.

Title: Solar heat reaction fluid carrying device
Inventor: SHIGIHARA HISAO
IPC: F04B17/00
Filed: 1979-12-19
Abstract: PURPOSE: To carry large volume of fluid by employing a sub-diaphragm, reserve tank and a cover glass as a circulation system for the cooling water while moving the fluid by pressurizing through a pressure-resistant tank by the expansion of a diaphragm coupled to a receiver due to the solar heat.  
     CONSTITUTION: The fluid flowing from a suction pipe 2 through a check valve 15 into a pressure-resistant tank 1 will flow naturally up to the water level. Here a fixed reflection face 5 will separate the solar heat from immediately above the facility from the optical axis of a receiver 4 by the cooling water which makes the glass cover water-tight and the solar heat is thus blocked. Upon opening of a control valve 12, the cooling water in the cover glass 14 will flow through a check valve 10 into a sub-diaphragm 8. A fixed reflection face 5 excluding the cooling water will collect the solar beam to the receiver 4, thereby the volatile liquid in a diaphragm 7 will be expanded abruptly to pressurize the fluid in the pressure-resistant tank 1 thus to pressurize and transfer the fluid to a position higher than a water supply port 3.

Abstract: PURPOSE:To enhance anti-noise characteristic and provide a smooth and effective operation by controlling the operation of a rear wheel steering means in accordance with the size of the angular velocity in steering, which has undergone a correction through subtracting a certain value from the absolute value of the angular velocity. CONSTITUTION:Through a cylinder the front wheels 1 are steered from a steering wheel 10, and a same-phase control valve 98 is operated using this oil pressure as a pilot pressure, and a same-phase steering oil pressure is applied to one oil chamber of a rear power cylinder 90. Meantime a controller 126 determines the absolute value of the angular velocity in steering from a signal given by a steering sensor 128, and the result undergoes a correction as subtracting therefrom a certain value, and an aid opposite phase control valve 100 is actuated on the basis of the corrected angular velocity and a signal from a car speed sensor 127. Thus an opposite phase oil pressure is applied to the other oil pressure chamber of the rear power cylinder 90, and the rear wheels 82 are steered with synthetization of these two steering forces. Thereby noise where the angular velocity is near zero, is cut which should enhance the anti-noise characteristic and ensure a smooth and effective operation.

Title: Discriminating method for electric characteristic of non- rectilinear resistor
Inventor: WATANABE MISUZU
IPC: G01R31/00
Filed: 1981-10-15
Abstract: PURPOSE:To perform a measurement for a short time in a manner that hysteresis is  prevented from leaving at a non-rectilinear resistor, by a method wherein a cooling is  made as a voltage is applied to the non-rectilinear resistor, a heating is then made as  the opposite ends of the resistor are short-circuited to measure a thermal stimulating  current, the good and bad of a limiting voltage ratio is discriminated by a second  peak, and the good and bad of a life characteristic by a third peak. CONSTITUTION:The measurement of a thermal stimulating current (TSC) is conducted  by heating of a copper plate 2 by means of a heater 5 and by cooling of the copper  plate 2 by means of a coolant, and after a sample is cooled to 150 deg.K under a condition  that a voltage is applied to the sample, it is short-circuited to measure a current,  which, simultaneously, flows when heating. As noted from samples 1A-1E shown in a  graph, three peaks are produced at the TSC with the increase in temperature, a ratio  of a peak value at a second peak value to a half value width has a close relation to a limiting voltage ratio characteristic, and the size of a peak value at a third peak has  a close relation to a life characteristic. Thus, the good and bad of the limiting voltage  ratio and the good and bad of the life characteristic can be discriminated by one-time  test.
