Title: Magnetic powder for high-coercive-force anisotropic bond magnet and its production
Inventor: SEZAKI KOJI
IPC: C22C38/00
Filed: 1990-09-03
Abstract: PURPOSE:To impart a high coercive force by forming an alloy powder consisting essentially of rare-earth elements, B, Fe, etc., added with a rare-earth oxide and having a specified particle diameter in a magnetic field, sintering and then crushing the formed body. CONSTITUTION:An alloy powder contg. 90-99wt.% of an alloy powder consisting essentially of 10-30 atomic% of a rare-earth element R (including Y), 2-28% B and 65-82% of M (>=1 kind among Fe, Co and Ni) and 1-10% of a rare-earth oxide consisting of >=1 kind among Nd2O3, Pr6O11, Dy2O3, Tb4O7 and Ho2O3 and with the average particle diameter adjusted to 0.5-50mum is formed in a magnetic field. The formed body is sintered at 900-1200 deg.C in a reducing or nonoxidizing atmosphere to obtain an anisotropic sintered magnet. The magnet is conventionally crushed into a magnetic powder having 20-500mum average particle diameter. The magnetic powder has a high coercive force, and an anisotropic bond magnet is provided with high productivity by using the powder.

Title: Air-conditioning system for vehicle
Inventor: KOBAYASHI SHIGERU
IPC: B60H1/12
Filed: 1982-12-29
Abstract: PURPOSE:To make it possible to prevent the lowering of a passenger's compartment while the temperature of blow-off air is not lowered, in a vehicle which uses engine cooling water as a heater source, by reducing the blast volume from its maximum volume when the temperature of blow-off air for the passenger's compartment is below a predetermined temperature. CONSTITUTION:When an air-conditioning system is set to a maximum heating mode by positioning a fan switch 23 at its maximum blast volume position 3 and turning on a heat switch 26 and a hot switch, if the outside temperature is low so that the heating capacity of a heater core is insufficient, a blow-off temperature detecting switch 20 is turned on to energize a relay 24 which opens its contact 24a but closes its contact 24b. Accordingly, a circuit consisting of a battery source, a motor 21, a resistor 22a and the contacts 24a, 25a is established, and therefore, the motor 21 is rotated at its intermediate speed, similarly to the condition which is established when a contact 23a is set at the position 2. This, when the outside temperature is low, even if the air-conditioning system is set at its maximum temperature and at its maximum blast volume, the fan motor is automatically made slow in its rotational speed to prevent the temperature of blow-off air from lowering, thereby the temperature of a passenger's compartment may be prevented from lowering.

Title: Production of piezoelectric ceramic
Inventor: SAKAI TAKENOBU
IPC: C04B35/00
Filed: 1992-09-02
Abstract: PURPOSE:To inexpensively produce a piezoelectric ceramic with the piezoelectric characteristic and strength improved and their variance reduced. CONSTITUTION:A piezoelectric ceramic compact is sintered in the presence of the lead-atmosphere powder and oxygen-atmosphere powder to produce a piezoelectric ceramic. The oxygen-atmosphere powder consists of an peroxide inert to the piezoelectric ceramic compact and is arranged under or around the compact as the seat powder or covering powder. Since the oxygen- atmosphere powder is inert to the compact, the piezoelectric characteristic and strength are not lowered. Meanwhile, as oxygen is generated from under or around the compact, a uniform oxygen atmosphere is formed around the compact, and the sintered compact is densified to improve and uniformize its piezoelectric characteristic and strength. The peroxide liberates oxygen in sintering and recombines with oxygen when cooled to form the reusable peroxide.

Title: Traveling object communication system
Inventor: SANO MITSUHIRO
IPC: H04W4/04
Filed: 1994-09-29
Abstract: PURPOSE: To surely enable the responder of a traveling object to communicate with a terrestrial station in a communication area by permitting the reception of an inquiry signal and data for the traveling object for a prescribed time when the traveling object enters the communication area and inhibiting the reception in the case other than one above. CONSTITUTION: Even when the responder of the traveling object enters the communication area of a data input/output part of a terrestrial station and a data transmission/reception part 16 and a communication control part 18 in the responder are started up, the reception data of a reception circuit 16a is inputted to the control part 18 only while the inquiry signal and the data are being transmitted from the terrestrial station, and the input of them to the control part 18 is inhibited in other cases even when the transmission/ reception part 16 and the control part 18 are started up. Therefore, the responder receives only the transmission data of the terrestrial station, and transmits only data for response.  Therefore, even when the circuit 16a fails in data reception from the terrestrial station and no data according to such data is transmitted, the data to be transmitted at the next communication timing is received by a responder side, which enables accurate data communication.

SOLUTION: Guide metal fittings are installed at both ends of one long-side side of a box body, a sand preventive sheet is mounted along the internal side faces of the box body, and the inside of the box body is filled with a large number of stone and a cover is set up. Consequently, the guide metal fittings of manufactured wire cylinders 10 filled with a large number of stone are piled up in rectangular parallelopiped shapes at a plurality of stages along the guide frames 9, 9' of caissons 1, 1'. The top faces of the bases of the wire cylinders 10 are directed towards the caisson body sides, and inclined at low places and installed. Earth pressure by the wire cylinders 10 strongly works to the rear sides of the caissons 1, 1', and force working to the guide frames 9, 9' of the caissons 1, 1' and the guide metal fittings of the wire cylinders 10 is reduced. Accordingly, a large number of back-filling stones which have been used are unnecessitated and back-filling works are simplified, and the suction of soil and sand can be prevented accurately.

Title: Circuit-switching device
Inventor: TSUNODA TAKANORI
IPC: G08C25/00
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To prevent communication abnormalities that are caused, when a control changeover switch is operated by using a delay means which delays the circuit changeover timing by a prescribed time. SOLUTION: When a circuit changeover switch 5 is turned off, the control right is set at a master station A, and also the priority of the station A is heightened for its selection request by the interlock conditions of relay contacts Z and W. When the switch 5 is turned on, the control right is set to a master station B, and the station A is unable to make a selection request. When a timer auxiliary relay 6 is switched on, a selection request switch 1 of the station A is operated, and the relay 6 is turned off in a state where a selection request switch 2 is operated and a circuit is switched to the station B, for example. When the circuit is switched to the station A, a contact X is switched with a fixed time delayed after the contact W is turned off. As a result of this communication errors which are caused at circuit switching can be prevented.
