Title: Magnetic recording medium
Inventor: ADACHI NORIO
IPC: G11B5/706
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To increase reproducing output and to decrease bias noise by specifying the compounding ratio of a first magnetic powder having a large specific surface area and a second magnetic powder having a rather small specific surface area and mixing the powders to form a single magnetic layer. SOLUTION: Because the first magnetic powder has a rather large specific surface area (small size), the amt. of the powder per unit volume can be decreased, which is suitable to realize high-density recording and to decrease bias noise. Because the second magnetic powder has a rather small specific surface area (large size), it has excellent orienting property and dispersibility and is suitable to increase reproducing output. The first magnetic powder having 40 to 45 m<2> /g specific surface area is mixed with the second magnetic powder having 30 to 35 m<2> /g specific surface area by 20:80 to 40:60 weight ratio, and the mixture is applied on a nonmagnetic supporting body 2 to form a single magnetic layer 3. By optimizing the compounding balance of the first magnetic powder and the second magnetic powder, performances above described can be obtd.  The difference of the coercive force between the first and second magnetic powders is preferably <=3 kA/m.

Title: Epitaxially growing method
Inventor: YONEDA KIYOSHI
IPC: H01L21/20
Filed: 1980-09-19
Abstract: PURPOSE:To prevent the occurrence of a disordered crack when epitaxially growing with thermal expansion coefficient different from a substrate by forming a notch to meet the final chip size in advance to the surface of the substrate. CONSTITUTION:The (0001) plane of Al2O3 is used as crystalline growing surface 6, and a notch 7 is formed by a laser machining to meet the final chip size in advance. A GaN8 is epitaxially formed thereon. Since the notch is formed in V shape, the GaN single crystal grown from the two surfaces collide with one another at the predetermined time and thereafter becomes polycrystal 20. Since the polycrystal 20 has space between the crystalline grains, the internal stress produced due to the difference of the thermal expansion coefficient is absorbed by the polycrystal 20, and no crack occurs.

Title: System and software method for radio data base station operation
Inventor: LOCKHART THOMAS W
IPC: H04W28/12
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To save time without bringing the lowering of a real signal, to reduce cost and to eliminate a 'false busy' signal by deciding whether or not a received signal strength index (RSSI) of a start part of a packet is larger than prescribed threshold and setting a busy bit to send a busy signal when it is larger than the prescribed threshold. SOLUTION: After a radio data base station (RDBS) 12 receives a start part of an uplink packet, the RDBS 12 measures an RSSI of the start part of the uplink packet and compares the measurement value with a prescribed threshold. When the RSSI of the start part of the uplink packet exceeds the prescribed threshold, the RDBS 12 continues to send a busy signal. When the RSSI of the start part of the uplink packet does not exceed the prescribed threshold, the RDBS 12 releases a busy signal and seeks a start point of another uplink packet. This operation eliminates the necessity for a hardware attenuator and maintains the quality of a received signal.

Title: Self-excited reactive-power compensator
Inventor: TOKIWA YUKIO
IPC: H02J3/18
Filed: 1992-04-24
Abstract: PURPOSE:To make it possible to continue stable operation of a self-excited reactive-power compensator, by limiting a reactive current command value provided from an automatic AC voltage adjustment circuit in a self-excited inverter to a given value when a detected voltage of an AC system becomes lower than a reference voltage. CONSTITUTION:A pre-controlled reactive current command value Iqo provided from an automatic AC voltage adjustment circuit 109 is limited to a given limiting value when an actual value (VAC) of a voltage in the system from an AC voltage actual value detecting circuit 108 becomes lower than a reference voltage (VACR). This limiting value is generated as a reactive current command value Iqo so that a DC over-voltage across a DC capacitor 2 is prevented even when a disturbed state occurs or even after the disturbed state is released. Consequently, during the disturbed state the self-excited reactive-power compensator can be operated without shutting off the reactive-power compensator from an AC system 4.

Title: Flow rate controlling device of water heater
Inventor: NAKAYAMA FUMIO
IPC: F23N5/14
Filed: 1977-11-02
Abstract: PURPOSE: To control hot water temperature and the number of rotation of fan motor and to increase or decrease the opening of valve port, so that the flow rate  can well follow the temperature change.  
     CONSTITUTION: Resistant value of thermistor 5 increases as the combustion progresses, and bridge circuit is kept balanced when the value becomes constant. Then, resistant value of thermistor increases and the condition of bridge circuit is unbalanced when hot water temperature goes up, and electric potential between A and B becomes large and the number of rotation of fan motor 18 increase. Therefore, by enlarging displacement of diaphragm 11 and making opening o valve port 13 of valve body 12 small, gas supplying rate to gas burner 6 is reduced, and on the contrary, electric potential between A and B becomes small when hot water temperature is below setting value, the number of rotation of fan motor 18 is decreased, and the opening of valve port 13 of valve body 12 is enlarged to increase gas supplying rate to gas burner 6, so that hot water temperature is always maintained at setting temperature.
