Title: Programmable read-only memory
Inventor: MASUDA HAJIME
IPC: G11C17/14
Filed: 1987-05-29
Abstract: PURPOSE:To certainly find a memory cell of an abnormal characteristic at the time of writing information, by providing a clamping circuit which clamps a writing passage at a voltage which is a little higher than the voltage produced when a writing current is supplied. CONSTITUTION:Memory cells M11, M12, M21, and M22 are connected with line wires W1 and W2 before writing. Diodes D11 and D12 which break down at a voltage which is a little higher than the voltage produced when a writing current is supplied are respectively connected between string wires B1 and B2 and earths. When writing is executed to the memory cell M11 in a non- conducted state, a writing current is made to flow to a line selecting circuit WD1 selected through the cell M11 and writing is executed. If the non-conducted state of the cell M11 before writing shows a normal characteristic when the writing is executed, proper writing is executed. If the non-conducted state shows an abnormal characteristic, the writing current flows through the diode D11 and writing becomes impossible, resulting in faulty writing. The faulty writing can be removed.

Title: Multiple-light-source communication device
Inventor: MORI MASAKAZU
IPC: H04B10/2513
Filed: 1979-10-23
Abstract: PURPOSE:To reduce the waveform distortion of a received signal at a receiving terminal, by providing a phase regulator at a transmitting side when information is sent by use of light sources. CONSTITUTION:A bipolar signal inputted to input terminal 5 is converted into a unipolar signal by bipolar/unipolar converter 1. This signal is applied to and scrambled by scrambling circuit 2 and then branched before being applied to electrophoto converters 3 and 3' respectively. Outputs of converters 3 and 3' are mixed in one by light synthesizer 4, whose output is sent from output terminal 6 to a party station. The constitution like this has phase regulator 7 interposed at the side of converter 3 longer in emitted-light wavelength. Consequently, the arrival time difference of a light pulse signal due to material variance properties of an optical fiber cable at the receiving side can be eliminated. Therefore, even when the receiving station converts the input into an electric signal by the photoelectric converter and then synthesizes the signal, the signal free from distortion can be obtained and the code error rate can be improved.

Title: Monitor device for operation of transformer
Inventor: SHINOHARA HIDEO
IPC: H01F29/04
Filed: 1984-07-04
Abstract: PURPOSE:To detect early a fault of an on-load top changer by detecting the vibration or acoustic levels produced at the time of changing, and discriminating the fault according to the duration of the detected levels. CONSTITUTION:The vibrations are produced at the wall of a tank 1 of an on- load tap changer at time of changing. These vibrations are detected by a vibration detector 5 and converted into electric signals by a signal converting circuit 7. These electric signals are applied to a filter circuit 8, and the duration of these electric signals are counted by a pulse counter 12. Then a decision processing circuit 13 converts the substantial tap changing time from the output value of the counter 12. This tap changing time is compared with the substantial tap changing time that is set previously in the normal state. Then a fault of the on- load tap changer is decided when the converted tap changing time is longer enough than the tap changing time in the normal state. The same effect is also obtained by using an acoustic detector in place of the detector 5.

Title: Heat exchanger
Inventor: YANAI SHINICHI
IPC: F28F13/00
Filed: 1978-11-09
Abstract: PURPOSE: To heighten the efficiency of heat exchange by removing attached bubble acting as a heat insulating layer from the entire surface of the heater through rotation of the fluid.  
     CONSTITUTION: A fluid for maintaining constant temperature from a pump 9 through a flexible pipe 8 introduced into a feed pipe 6. As it enters the bottom of the heat exchanger body 1, the fluid begins to turn along the inner wall of a cylinder because is flows from the tangential direction of the circle thereof. With a discharge pipe 7 above the body 1, the turning fluid flows upward forming a vortex and fed to the section intended to maintain constant temperature through the discharge pipe 7. In this case, the higher the outflow pressure from the pump 9 is, the greater the speed of the flow is. Thus, the bubble attached on the surface of the heater 4 is separated and carried away on the flow outside the body 1. In this manner, the attached bubble acting as the heat insulating layer can be removed from the enter surface of the heater 4, thereby affording a better heat exchange.

Title: Magneto-resistive element, reproducing head and recording and reproducing system
Inventor: HAYASHI KAZUHIKO
IPC: G11B5/39
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To decrease reproduction noises and to obtain good/SN and bit error rate by using a tunnel junction element consisting of a free layer/nonmagnetic layer/fixing layer and providing part of the free layer with longitudinal bias layers. SOLUTION: A lower shielding layer 1 and the free layer 6 are successively laminated on a substrate and the patterned longitudinal bias layers 7 and insulating layers 8 are laminated thereon and further, an upper electrode layer 9 and an upper shielding layer 10 are laminated thereon. The portion between the fixing layer 3 and the free layer 6 constitutes a magneto-resistive film. When current is passed from the upper electrode layer 9 to the lower electrode layer 2, the current passes between the insulating layers 8 arranged on the right and left from the upper electrode layer 9, passes between the free layer 6 and the fixing layer 3 and flows to the lower electrode layer 2. Since the longitudinal bias layers 7 are insulated from the flow of the current, the layers do not participate in the flow of the current.  Since the longitudinal bias layers 7 are directly laminated on the free layer 6, the free layer 6 is sufficiently longitudinally biased.
