Title: Quadrangular pyramid vane wind force prime mover
Inventor: KINO MORIYASU
IPC: F03D3/06
Filed: 1989-11-27
Abstract: PURPOSE:To convert wind force into power in a highest efficiency by changing vertical rotation into horizontal rotation, and by making vanes of a quadrangular pyramid, and also by making the distance between the turning shaft and the vane longer than the height of the quadrangular pyramid vane. CONSTITUTION:Two sets of quadrangular pyramid vanes are crossed at the middle point so as to be perpendicular to each other, and the interval of vanes is made to be at right angles, and four quadrangular pyramid vanes are directed to the same direction at the same point, and opposite vanes are directed to the opposite directions, and a turning shaft is fitted at the crossed middle point, and fixed so that the vanes and the turning shaft can be rotatingly driven together. Then, wind force is converted into rotating power in such a state that a prime mover is fixed, independently of the direction of wind, and the rotating power is utilized as a power source by the turning shaft. By making the vanes of a quadrangular pyramid, the difference in the wind pressures to the right and left vanes becomes maximum, and by making the distance between the turning shaft and the vane longer than the height of the quadrangular pyramid vane, at least two quadrangular pyramid vanes can be fitted to one set of the wind force prime mover without interfering the wind velocity and wind pressure, thus the maximum rotating power can be obtained at a given wind velocity.

Title: Semiconductor laser
Inventor: HORIKAWA HIDEAKI
IPC: H01S5/00
Filed: 1990-11-14
Abstract: PURPOSE:To decrease an increment in the width of a spectral line when wavelength is variable by giving a stripe shape to an emission part, a phase control part and a wavelength selection part, reducing the width of an upper clad layer to the same width of an active layer and increasing the isolation resistance of each of the emission part, phase control part and wavelength selection part. CONSTITUTION:A emission part 120, a phase control part 130 and a wavelength selection part 140 are placed in a stripe shape in the direction of the laser resonator length on an n-InP substrate 110 having an n-InP buffer layer 110a, and an inverted mesa construction is given to the section in the direction orthogonal to the stripe direction. Also, the width of an upper clad layer 125 is made very small compared to the conventional one. Since this width is very small, the resistance of the upper clad layer 125 connecting each portion becomes higher than the conventional one. Moreover, a current block layer 160 has a semi-insulating InP layer 165, and the isolation resistance of the emission part 120, phase control part 130 and the wavelength selection part 140 becomes almost ten times as high as that of the conventional one. Thus, when the phase control part 130 is operated, the currents flowing from the phase control part 130 to the emission part 120 and the wavelength selection part are reduced.

Title: Monitor for apparatus in nuclear reactor
Inventor: SUDO AKIRA
IPC: G21C17/02
Filed: 1990-11-14
Abstract: PURPOSE:To always monitor change in the quality of a reactor water from outside and check soundness of apparatus at all times by sensing the electroconductivity of the high temp. reactor water at all time by the use of a high temp. electroconductivity sensor, and taking out the sensing signal to outside the reactor through leads. CONSTITUTION:When a BWR plant is started, a sensing signal from a high temp. electroconductivity sensor 1 installed in the neighborhood of an applicable apparatus in nuclear reactor is sent through leads 8 to an electroconductivity measuring apparatus 10, situated outside of the reactor, where the conductivity of the high temp. reactor water is measured continuously. If as the worst case a crack is initiated in the apparatus in the neighborhood of the high temp. conductivity sensor 1, metal ions elude out of the surface into the reactor water to cause abrupt rise of the value of conductivity, which has been measured by the conductivity measuring apparatus 10 continuously. Accordingly crack initiation in the apparatus material can be sensed quickly from this change in the conductivity.

Title: Receiver
Inventor: TAKAYAMA KAZUO
IPC: H04B17/309
Filed: 1986-12-26
Abstract: PURPOSE:To contrive to improve the sensitivity of separation control by obtaining a control signal of a prescribed pulse width in response to noise detection by a noise elimination circuit and integrating the said control signal so as to ensure the detection of multi-path noise. CONSTITUTION:A noise detection section 3 detects a noise from an input signal in a noise rejection circuit 1. A control pulse Generating section 4 generates a control signal having a pulse width in response to the frequency of output of the detection section 3. A noise pass inhibition section 5 inhibits the transmission of the input signal to the output terminal in response to the pulse width of the said control signal. A multipath detection circuit 2 uses a control pulse generating section 6 so as to use the detection signal from the detection section 3 as a trigger thereby generating the 2nd control signal having a prescribed pulse width and the integration circuit 7 integrates the control signal to detect the multipath. Since the control pulse generating section 6 uses the output of the detection section 3 as a trigger to generate the 2nd control signal of a prescribed width, even the multi-path noise appearing frequently does not give effect of detection delay. Thus, one-shot pulse noise in the receiving sound is suppressed and the multi-pulse noise is suppressed.

Title: Magnetic recording medium
Inventor: SASAMOTO SAYAKA
IPC: G11B5/73
Filed: 1989-11-29
Abstract: PURPOSE:To obtain a medium having excellent durability and traveling stability by incorporating block- or graft-copolymers having a structural part compatible with a binder and another structural part showing lubricating property into a magnetic layer. CONSTITUTION:A magnetic layer containing magnetic powder and a binder is formed on a nonmagnetic supporting body to constitute the magnetic recording medium 2, on which a magnetic head 1 is brought into contact. The whole surface of the medium 2 facing to the head 1 is covered with a lubricating layer 3 containing the lubricating structural part 4 of the copolymers. Conventionally, when the head 1 slides, a liquid film is formed on the surface of the medium to promote effective fast sliding. However, when the head 1 removes off the liquid film from contact area, the head 1 directly contacts with the medium and large driving torque is needed to start sliding again. By the method of this invention, the lubricating structural part 4 with low interfacial energy can remain between the medium and air, friction in the initial sliding can be reduced.

Abstract: PURPOSE:To protect the data by providing a memory flag which is set at '0' when the final address is programmed and then set at '1' with erasion of the ultraviolet rays and suppressing the program operations of all addresses when the memory flag is kept at '0'. CONSTITUTION:A memory part 1 and a memory flag 2 are set in the programming state with a program mode 10 set at '1' and the output of an AND gate 3 set at '1' respectively. Meanwhile '1' is programmed and the output value '1' is supplied to the gate 3 when an address 20 is set at 00 - FE in regard of the flag 2. When the address 20 is set at the final FE, an all-1 detecting means 4 outputs '0' and at the same time '0' is programmed for the flag 2. As a result, the output of the gate 3 is set at '0' and both the part 1 and the flag 2 are set in the program suppression state. Thus the data once programmed is protected.
