Patent JP-H03297237-A (JP)
Title: Data transmission system
Inventor: TAKANISHI ISAO
IPC: H04L7/00
Filed: 1990-04-16
Abstract: PURPOSE:To extract a clock signal independently of synchronization/ asynchronization communication by adding a simple bit inversion processing function to a data transmitter and not increasing nor decreasing a bit number but only inverting data bits in a data bit pattern. CONSTITUTION:A transmission data generating section 8 of a data transmitter 1 at a sender side generates a data to be sent and a scramble processing section 9 processes the transmission data. When the one and the same consecutive code discrimination section 10 discriminates consecution of a same code in a transmission data after scrambling in excess of a specified number, a bit inversion processing section 11 inverts a relevant bit and sends the result to a data transmission line 2. A data transmitter 1 at a receiver side receives a reception data 13 from the transmission line 2. When no bit inversion is implemented at the sender side, a clock extraction section 3 generates a clock signal 12, it is used by reception data processing sections 5, 6. A data 13 is processed by a processing section 5 via a descramble processing section 4. When bit inversion is implemented at the sender side, the processing by the extraction section 3 has no problem but the inverted bit via the processing section 4 is detected as an error by an error check section 7.

IPC: H04L12/00
Filed: 1995-04-24
Abstract: PURPOSE: To eliminate the influence of transmission delay in the communication of satellite stations except for a hub station by identifying whether the address of a communication destination is set in an address list or not, executing communication by means of a satellite when it is set and executing communication through a network on the ground when it is not set. CONSTITUTION: The address (it is set to be 3) of the host 113 of the hub station is set as an opposite party with which communication is executed through the satellite 10 in the respective address lists 123 and 133 of the transmission devices 121 and 131 of the satellite stations 12 and 13. The address of a terminal 124 is set to be 1 and the address of a terminal 134 to be 2. Communication is executed from the terminal 124 of the satellite station 12 to the terminal 134. Thus, the address comparison part 122 of the device 121 takes out the address 2 of a destination and compares the address with an address in the address list 123 when information to which the address 2 of the destination is added is inputted.  Since they are not matched in the case, the route of a ground network 14 is selected, and it is connected with the terminal 134 of the satellite station 13 of the address 2 through the ground network 14. When communication is executed from the terminal 124 with the address 3 of the host 113 as the destination, the comparison part 122 of the device 121 detects that it is matched with the address which is set in the list 123. Communication is executed with the host 113 of the station 11 through a satellite circuit in the device 121 and an antenna 120.

Title: Shock control method and apparatus for non-excitation operation type electromagnetic brake
Inventor: OSONO HISAO
IPC: F16D65/18
Filed: 1988-04-20
Abstract: PURPOSE:To restrain a temperature rise of a coil by providing a Hall element for detecting magnetic flux on the surface of an electromagnetic core opposite to a disc, in which core an exciting coil of an electromagnetic brake is accommodated, and controlling the exciting electric current in such a manner that the operating force applied to the disc is constant. CONSTITUTION:A coil 2 is buried in a groove of an electromagnetic coil 1, and a Hall element 7 is disposed on the surface opposite to an armature 3. The armature 3 is pressed to an outer disc 5 by a compression spring 6, and an inner disc 4 is clamped between linings 11 to form a very small gap Lg between the electromagnetic core 1 and the armature 3. A change of electromagnetic flux amount in the gap Lg at the time of sucking the disc is detected by the Hall element 7, and exciting electric power to the coil 2 is controlled according to the detected change so that force applied to the disc 4 is kept to a designated constant value. Thus, while the brake is released, exciting electric current is decreased to relax a limit of electric current applying time due to a temperature rise. Further, at the completion of releasing the brake, the electromagnetic core and the armature will not contact impulsively so as to prevent the production of noise.

Title: Temperature compensating method for ultrasonic range finder
Inventor: NAKAI YUTAKA
IPC: G01S7/52
Filed: 1989-04-20
Abstract: PURPOSE:To enable an accurate distance measurement to be performed without delay even when an external temperature suddenly changes by constructing an ultrasonic range finder such that a temperature compensation is conducted by using a temperature change detected by measuring a unit distance by an ultrasonic wave. CONSTITUTION:The space propagation time To of an ultrasonic wave signal for which the signal transmitted from an ultrasonic wave generator 10 is propagated through a unit distance lo and received by an ultrasonic wave receiver 11 is counted by a counter circuit 13 to be fed to an arithmetic circuit 7. When the circuit 7 is given the time To from the circuit 13, the circuit 7 calculates a temperature correcting compensating value alpha and stores it. On the other hand, a time Tx for which an ultrasonic wave signal P fed from an ultrasonic wave generator 2 is reflected from an object 1 to be measured and received by a receiving circuit 5 via an ultrasonic wave receiver 4 is counted by a counter circuit 6. When given the time Tx from the circuit 6, the arithmetic circuit 7 calculates a distance Xo to the object 1 by using a sonic velocity at a reference temperature to and corrects the value of the distance Xo with the correcting value alpha. As a result, the measured value of the distance to the object to be measured can be corrected without delay.

Title: Frp-molded item with reinforcing layer and its molding
Inventor: HIKITA YOSHIHIKO
IPC: B29C41/22
Filed: 1988-04-20
Abstract: PURPOSE:To prevent a reinforcing layer from falling off from a FRP-molded layer and generation of crack in the FRP-molded layer, by laminating integrally the reinforcing resin concrete layer on the back of the FRP-molded layer through a F-type resin layer. CONSTITUTION:A mold A is coated with a release agent 1 on which a FRP-molded layer 3 is formed through a gelcoat layer 2 by means of hand lay-up or spray-up. Then, a mucilaginous soft F-type resin layer 4 is applied in a desired thickness on the place where a reinforcing layer B is formed during the half-hardening of the FRP-molded layer 3. Then, a reinforcing resin concrete layer 5 is placed directly on the half-hardened-state F-type resin layer 4, a leg rod 5b is in advance formed in a separate process. A backing reinforcing plate 5a has mucilaginous resin concrete applied around the leg rod to integrate and harden the whole. The resin concrete is water-impermeable and corrosion-resistant, no water intruding into the boundary part between the FRP-molded layer and the resin concrete and the deterioration in durability does not occur. Because the F-type resin 4 between the FRP-molded layer and the reinforcing resin concrete layer mitigates the stress caused from the difference in ratio of heat shrinkage between said both layers, the falling-off of the FRP-molded layer and crack generation thereon can be prevented.

Title: Device for controlling engine
Inventor: TAKADA MINORU
IPC: F02D41/00
Filed: 1988-04-20
Abstract: PURPOSE:To obtain an operation having no sense of incompatibility by reducing the correcting width of a controlling characteristic correcting means with the rise in detected vehicle speed to make a controlling characteristic approach a basic characteristic and electrically driving a throttle opening according to a determined target throttle opening. CONSTITUTION:At the time of a steady operation, a target throttle opening determining means A determines a target throttle opening corresponding to an accelerator operating quantity detected by a detecting means B based on a basic characteristic to electrically drive a throttle valve D via a driving means C. On the other hand, when judged to be an accelerating time by a judging means E, a controlling characteristic is corrected in the direction of increasing the throttle opening more than that of the basic characteristic with respect to the same accelerator operating quantity by a correcting means F to determine a target throttle opening. In this case, the correcting width is reduced with the increase in vehicle speed detected by a detecting means G by a reducing means H. Thereby, the output responsiveness at the time of accelerating can be increased while preventing the sudden change in throttling at the time of shifting to the steady operation, obtaining operating feeling with no sense of incompatibility.

Title: Manufacturing for semiconductor wafer
Inventor: KUBO YOICHI
IPC: B24B9/00
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a semiconductor wafer, in which an abrasion step for the wafer can be carried out accurately after a semiconductor ingot is sliced into the wafers, by determining the direction of crystal axis of the wafer, which is slanted in a certain direction, through operator's visual observation until the abrasion step for the wafer in a given direction is finished. SOLUTION: After an orientational flat finishing step is carried out for a semiconductor ingot 1, a shallow groove 3 is formed at a position a little away from a center of an orientation flat part 2. After the ingot 1 is sliced, a face of crystal axis is so determined by observing whether the cut part is located right or left in the view from the top face. As a result, the direction of the crystal axis can be determined easily with the visual observation.
