Title: Lining work for tunnel
Inventor: MASUDA MASAKAZU
IPC: E21D20/00
Filed: 1989-06-27
Abstract: PURPOSE:To integrate a tunnel with the ground by a method in which concrete is placed into the space between the inner wall of a tunnel of a given length and a formwork, and prestressed anchors are radially driven from the inside of the concrete into the ground. CONSTITUTION:A shield jack 7 is contacted with the end face of a formwork 9, and a press jack 6 is contacted with the front end of an unhardened lining concrete 12. The jacks 6 and 7 are extended to advance a shield excavator 1. The formwork 9 has one or more injecting ports 13 for ready-mixed concrete and inserting holes 15 for prestressed anchors 14. As the lining concrete 12 is constructed and the concrete hardens to a desired hardness, the anchors 14 are driven radially into the ground from the holes 15 by means of an anchor driver 22. The concrete can thus be strongly integrated with the ground.

Title: Detecting device of actual steering angle for vehicle
Inventor: NEGISHI MASAMI
IPC: G01B11/26
Filed: 1989-06-28
Abstract: PURPOSE:To enable precise detection of an actual steering angle of a vehicle by a method wherein an object to be detected is fitted coaxially to a rotating shaft of a road wheel and the amount of a change in an angle of this object is detected directly. CONSTITUTION:An interference filter 3 receives an image signal from an object 2 to be detected which is generated with a change in an angle of a vehicle and sends to a condenser lens 4 the image signal wherefrom a jamming signal is removed. A one-dimensional CCD array 5(6) sensing a light signal from the lens 4 is a photodetecting element which outputs a voltage signal being proportional to a gray image of the sensed image. When the object 2 to be detected which is different in a gray signal from the color of a road surface is detected below the filter 3, accordingly, a unit cell detecting the object 2, out of unit cells of the array 5(6), delivers an output at a prescribed output level and the movement of the object 2 can be detected therefrom. In other words, an actual steering angle can be detected on the basis of the amount of shift of a transverse signal of the object 2 to be detected and a distance between the arrays 5 and 6.

Title: Intermittent reception system of mobile radio communication system
Inventor: MURATA YOSHITOSHI
IPC: H04W88/02
Filed: 1985-07-27
Abstract: PURPOSE:To attain effective utilization of a radio wave by using a timer correction signal sent from a master station to allow all slave stations to reset simultaneously a reception period setting time, correcting an error of a reception period setting timer between each slave stations and allowing the master station to have only to send a radio wave when the slave station is in a reception state. CONSTITUTION:A reception period management timer 3 of a master station A and a reception period setting timer 12 of all slave stations are subject to set/timeout synchronously. A schedule timer 6 counts several times or over of a reception period managing timer 3, the split reception operation is conducted for several times or over consecutively and when a deviation due to an error of the reception period setting timer 12 among the slave stations is caused, a trigger is sent to correct it. When the master station A receives neither a synchronization establishment request signal (b) from the slave station B nor the trigger from the schedule timer 6, the reception period management timer 3 counts the time T1 to check whether or not timeout exists, and when the time reaches T1, after the timer 3 is reset, the state returns to the standby state. Even when the power of plural slave stations is turned on independently, all the slave stations are synchronized by using a new timer correction signal.

Title: Development sheet for pressure sensitive duplicate
Inventor: ONO YUKO
IPC: B41M5/50
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To obtain a clear ink-jet recording image and to prevent blur and reduction in density of an image in the case of being wetted by water by providing a development layer containing an electron receptible developer as a main component on a substrate and regulating a contact angle touching distilled water on the surface of the development layer to a specific range. SOLUTION: A contact angle touching distilled water on the surface of a development layer is regulated to a range within 70-120 degrees. When the contact angle touching distilled water at 10 seconds after drop is <=70 degrees, a clear ink-jet recording image is made difficult to be obtained. Further, in the case of exceeding 120 degrees being nearly same degree as the contact angle of base paper, grouping paste is made difficult to be penetrated and grouping of a duplicate set is made impossible and a function of pressure sensitive duplicate paper is remarkably deteriorated. The contact angle touching distilled water on the surface of the development layer is regulated to a range within 70-120 degrees by adding a sizing agent and a water repellent agent to the development layer and incorporating various synthetic resin emulsions.

IPC: B29B7/28
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To decrease temperature in a short time and to reduce a kneading time by injecting the cooling medium of a feeder into a kneading chamber when the kneading temperature of main components excluding a vulcanization system component has reached a temperature or above at which the vulcanization system component can be added. SOLUTION: The kneading temperature of a kneading chamber 4 having a rotor 8 is detected by a temperature sensor 14, a feeding passage 17 which communicates with the kneading chamber 4 and passes a cooling medium C is installed, and the cooling medium C is fed by a feeder 40 in communication with the feeding passage 17. The injection of the cooling medium C of the feeder 40 is detected by a temperature sensor 15, when the kneading temperature of main components Bb excluding a vulcanization system component Ba has reached a temperature or above at which the vulcanization system component can be added, actuation is done by a controller 20. Since kneading is done while kneading materials being cooled, a kneading time can be reduced.  Since the temperature increase is detected and the cooling medium is injected while the main components is kneaded and the temperature is decreased to a kneadable temperature, kneading work can be done without being interrupted.

IPC: H01L39/22
Filed: 1988-07-06
Abstract: PURPOSE:To enable detection of the intensity of a magnetic field by applying a known current on a detecting element formed of a superconductor and by detecting a change in an electrical characteristic at the time when the magnetic field is made to act. CONSTITUTION:A prescribed voltage is impressed on the opposite ends of a ceramic superconductor 11 from an AC power source 14 through current electrodes 12. An output voltage of each of voltage electrodes 13 provided in the opposite ends of the superconductor 11 is amplified, sliced and subjected to double wave rectification and thereby a binary signal is obtained. Moreover, this signal is passed through an inverter circuit to obtain a pulse signal, the pulse width of this signal is measured, so as to detect a change in the intensity of a magnetic field 16. Since the polarity of a current impressed on the superconductor is varied alternately, according to this constitution, the effect of an electromotive force or an action of rectification is removed substantially, and since a part of large amplitude is saturated and taken out as the binary signal, in addition, the change in the intensity of the magnetic field 16 can be detected without necessitating amplification of high precision with regard to an amplification factor and noise.
