Title: Ceramic electromagnetic flowmeter and its manufacture
Inventor: NISHIJIMA TSUYOSHI
IPC: G01F1/58
Filed: 1987-09-30
Abstract: PURPOSE:To obtain the ceramic electromagnetic flowmeter which has a clamping part between SP and KH at low cost with high reliability by forming a clamping ring by casting at the connection part between a ceramic pipe and a metallic housing. CONSTITUTION:The clamping ring 7 is formed by casting at the connection part between the ceramic pipe 1 and housing 2 by using Al or Al alloy AL clamped to the pipe 1 by chemical reaction. A reaction layer 71 is formed by making the ring 7 react chemically on the pipe 1 or housing 2. Namely, the AL in a solid state is put in a reservoir part 81 provided above a jig 8 and while a load is placed on a weight 82, etc., from above, heating is carried in an atmosphere of inert gas such as nitrogen and fused AL flows in the part of the ring 7 from a pouring gate 811. At this time, the atmosphere in the furnace is formed of the nitrogen, etc., so AL having no oxide film can be brought into contact with the surface of the pipe 1 without oxidizing the AL. Then pressure is applied to the connection surface by the solidification contraction of the Al because of the difference in the coefficient in the heat expansion of the pipe 1 to join the AL with the pipe 1 chemically and tightly.

Title: Image scanner servicing as reflection and transmission
Inventor: KODERA HIROAKI
IPC: H04N1/04
Filed: 1985-11-05
Abstract: PURPOSE:To allow the same scan mechanism to read a reflected original and a transmitted one and to attain device's miniaturization and economization by setting an original loading surface to a uniform white reflection surface and providing a gamma correction circuit selectively inserted through an original selection switch. CONSTITUTION:The transmitted or reflected original 102 is wound on the surface of a cylindrical drum 101, and rotated and scanned by a main motor 103. Spot light is used for the transmitted and reflected originals in common, and leads an optical signal from the original 102 to a read sensor 108. For the transmitted original, after spot light transmits said original, the original is surface-reflected by the white reflecting surface of the drum, and the light again transmits the original and reaches the read sensor 108. Namely, for the transmitted original, the optical signal is detected after spot light passes the original approximately twice. The gamma correction circuit 112 corrects the distortion of the transmitted optical signal, which is caused by passing twice, and outputs a linear transmissivity signal.

Title: Large turning program steering method
Inventor: TANAKA HIROSHI
IPC: G05D1/02
Filed: 1988-10-03
Abstract: PURPOSE:To set the attitude of an unmanned vehicle to be parallel to a guidance line at the time of returning on the guidance line and to shorten a travel distance when the unmanned vehicle comes to be parallel by gradually and reversely returning a steering angle after the front wheels of the unmanned vehicle have gone past the corner of the guidance line, steering the wheels and travelling the vehicle for a prescribed distance. CONSTITUTION:When the unmanned vehicle approaches the corner where the guidance line 49 bends at right angles, the guidance travel of the unmanned vehicle which travels along the inductive line 49 is interrupted and it is caused to go straight on. When the front wheels of the unmanned vehicle have gone past the corner, the unmanned vehicle is gradually steered until it comes to the previously set steering angle, and the vehicle is travelled for the prescribed distance on the outer side of the corner. Then, the unmanned vehicle is gradually steered in an opposite direction to the steering angle. Thus, the attitude of the unmanned vehicle at the time of returning to the guidance line 49 comes to be parallel, and the travel distance until it comes to be parallel becomes short.

Title: Device changeover system and device changeover method
Inventor: NIIMI HIROAKI
IPC: H04L12/70
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To simply cope with device changeover even on the occurrence of a more sophisticated fault of a system device group and to relieve a load of a device supervisory unit. SOLUTION: System devices are interconnected as a mesh and the devices are supervised by a method such that supervisory is conducted among the device of a same kind or a check packet is added to a transport stream. In the case of device supervision among the devices of the same kind, on the occurrence of a fault in a device 12, the device 12 sends device information to a standby device 13 and then the faulty device 12 is replaced with the standby device 13. In the case of adding a check packet to a transport stream, on the occurrence of a fault in the device 12, the device 12 multiplexes the device information with the transport stream, transmits the multiplexed stream to the standby device 13 and switches a path for the information after that to change over the device. Similarly, the device configuration can be changed even during operation. Thus, high reliability can be obtained.

Title: Method and apparatus for measuring position and posture of excavation head
Inventor: NAKANO YUSUKE
IPC: G01C15/00
Filed: 1985-11-05
Abstract: PURPOSE:To simply measure the absolute position and azimuth angle of an excavation head only by measuring induced voltage, by calculating the angle of rotation of a magnetic field element generating max. induced voltage by the magnetic field from a magnetic field generating element. CONSTITUTION:A transmitter 4 and a transmitting coil 2 are arranged on the ground at both sides of a tunnel T to be excavated and a pit side transmitted-receiver 8 and a personal computer 9 are further arranged so as to be connected to each other. When a receiving coil 3 is rotated to two directions crossing vertically by a receiving coil driving part, the voltage inducted in the receiving coil 3 changes so as to follow the rotational operation of said coil 3. In this case, the induced voltage changes in a sine wave form according to the change in the angle of rotation of the receiving coil 3 and, when the angle of rotation of the receiving coil is 80.4 deg., the induced voltage becomes max. Therefore, a characteristic drawing of the angle of rotation of the receiving coil showing max. induced voltage and the horizontal distance R and vertical distance Z between the transmitting coil and the receiving coil is preliminarily formed and the receiving coil in an excavation head is rotated on the plane of an advance direction and the plane vertical thereto to induce voltage. Only by measuring the induced voltage at this time, the position and azimuth angle of the excavation head can be simply measured.

In an exhaust stroke, a port 9a of a rotary slide valve 9 on one side overlaps with the exhaust port 5. As a result, the exhaust gas is exhausted into an exhaust manifold 7. In the suction stroke, the rotary slide valve 9 closes the exhaust port 5, while a port 8a of the rotary slide valve 8 on the other side overlaps with a suction port 4. As a result, the air-mixed gas is sucked into a suction manifold 6. After this, the piston 17 goes up again to close both suction port 4 and exhaust port 5, thereby attaining the next compression stroke. The same operation as this is conducted in the combustion chamber 22 situated below, as well.
