Title: Oxidation resistant treatment of carbonaceous material
Inventor: MORIMOTO TATSUO
IPC: C04B41/87
Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming an SiC coating layer in an oxidation resistant treatment of a carbonaceous raw material, suitable for treating a large-sized mass production product, excellent in adhesion property of an Si source with the raw material under a heat treatment, and not generating a blister and a distortion at the surface of the raw material. SOLUTION: This method of an oxidation resistant treatment of a carbonaceous raw material is to react carbon on the surface of the carbonaceous raw material with silicon for converting the composition of the surface of the carbonaceous raw material to silicon carbide (SiC). In this case, as a source 11 (Si source) for supplying Si necessary for the reaction, a powder of a material containing silicon added with a powder of a ceramic material and further added with a thermosetting resin 12, is used. Also, characteristics of the process are: using a method of applying the powder instead of using a crucible treatment and using a raw material powder consisting of an oxide as a powder of the ceramic material and a powder of silicon nitride (Si3 N4 ) as the Si source.

Title: Fire sensor
Inventor: WADA TAKETSUGU
IPC: G08B17/10
Filed: 1992-08-26
Abstract: PURPOSE:To provide a fire sensor in which power consumption can be reduced without operating a backup function in a period where no backup function is required. CONSTITUTION:A sensor circuit 11 detects smoke density, and outputs a corresponding digital value. An arithmetic control part 12 transmits an information signal based on the output of the sensor circuit 11 in a time division multiplex transmission system at every polling from a receiver, and outputs a reset signal from a reset terminal RST after sending the information signal. Also, a transmission/reception circuit 13 starts up a program which sends out the information signal by inputting an interrupt signal to a first interrupt terminal IHT1 at every polling from the receiver. A backup circuit 14 is reset by the reset signal, and starts up a program for backup by inputting the interrupt signal to a second interrupt terminal IHT2 after the lapse of constant time after reset. The time of time interval operation of the backup circuit 14 is set longer than a polling period.

Title: Information recording and reproducing device
Inventor: MINAGAWA TAKASHI
IPC: G11B20/10
Filed: 1987-09-11
Abstract: PURPOSE:To efficiently execute data processing concerning the determination of a starting track of the retrial when a tracking error occurs by checking data between a generation address and a present address when the tracking error occurs. CONSTITUTION:When the tracking error occurs, the generation address and the present address, i.e., the jumped-over address, are stored in a memory 34. The storage of the generation address is executed by storing the output of a regenerator 33 in the memory 34 through a control circuit 36 by means of a signal from a tracking error detecting circuit 37. The present address is detected by the regeneration of the quantity of light since the quantity of light is lowered to a regeneration level simultaneously when a tracking error detecting signal is outputted, and the present address is stored in the memory 34. Next, the comparison of a generated track address with a present track address is executed, and the determination of a check-starting track and a check-ending track is executed. Thus, the data processing is executed efficiently by specifying a checking action to an area where a data destruction possibly occurs by the tracking error.

When a required active force is given to the particles, they are affected by the floating magnetic field of the magnet 29.  An ion generating device 70 discharges a negative ion flow in radius direction, this flow is immediately turned by 90 deg. by a magnetic field, enters the center surface 9, and enters the inside of the space 10. A proton accumulation ring 3 is provided from a central belly part 30 of a roll frame 35.

Title: Broadcast receiver
Inventor: YUKITOMO TOSHIHIRO
IPC: H04B1/16
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To receive multiplex broadcast without caring antenna extension/ retraction by operating an FM multiplex reception part, receiving the multiplex broadcast and storing demodulated multiplex data when FM broadcast reception is not selected and a vehicle power source switch is turned on. SOLUTION: A power antenna AA is extended, a diversity operation is started, and FM multiplex data are received and stored in a storage part 12. When AM is not selected, and the antenna AA is extended, it is retracted and switched to a glass antenna BA not to be extended/retracted. When AM is selected, AM reception is performed by the antenna AA and the antenna AA is not be retracted. Thus, since the reception part is turned on by a power source switching part 14 for turning on only the FM reception part, FM multiplex signals received by the antenna BA are stored in the storage part 12 as FM multiplex data demodulated by an FM tuner 2.

IPC: F16C32/04
Filed: 1987-09-10
Abstract: PURPOSE:To make the frictional force of the bearing in the caption extremely small so as to aim at extension of its life by using a superconductor for one of an outer ring and an inner ring and a magnet for the other so as to use Meissner effect of both rings. CONSTITUTION:A superconductor is used for one of an outer ring 1 and an inner ring 2 and a magnet is used for the other, but the superconductor can be used for any one of both. Further, the superconductor and the magnet can be employed in the whole of the outer ring 1 and the inner ring 2 and the magnet can be either a permanent magnet or an electromagnet. And, with due regard to the case of the contact of the outer ring 1 with the inner ring 2 by any possibility, material pieces 5 having a small coefficient of friction can be joined with the rings. A gap can be maintained between the outer ring 1 and the inner ring 2 by Meissner effect so that the coefficient of friction of this bearing becomes extremely small. Accordingly, super high speed rotation becomes possible and the life of the bearing is remarkably extended.

IPC: H04N1/113
Filed: 1983-12-02
Abstract: PURPOSE:To evade the variation in shape of a light spot due to a shift in scanning position without requiring strict work precision by moving three mirrors which change the optical path of incident light by 90 deg. on an x-y plane without changing their relative positions. CONSTITUTION:The three cubic mirrors 1, 2, and 3 which change the optical path of incident light by 90 deg. are arranged on specific supports. The incident light enters the mirror 1 in parallel to a (z) axis and is deflected in an (x) axis by 90 deg. then in an (y) axis direction by 90 deg. through the mirror 2, and further deflected in the (z) axis direction by 90 deg. through the mirror 3. Those three mirrors are moved in the (y) axis direction without changing their position relation to obtain a light spot P2, and moved similarly in the (x) axis direction to obtain a light spot P3. Thus, they are moved on the x-y plane to move the light spot freely, without requiring conventional strict work precision, and also make the spot shape invariably constant.
