Title: Floor material having releasable prestress and method for making canal by cast wall technique using said material
Inventor: ARAN JIERAARU MONE
IPC: E04B5/43
Filed: 1990-01-31
Abstract: PURPOSE: To decrease the thickness of a cast wall and reduce the costs by installing floors consisting of prestressed floor material between side walls, relieving the prestress, and generating on the cast wall a counter-force to resist against the thrust generated in the wall. CONSTITUTION: A prestressed concrete floor material 1 approx. in a rectangular shape has a T-section, and in this floor material 1, a plurality of prestressed metal strands extending in parallel and in the longitudinal direction are embedded over the whole transverse length. Each strand 2 is formed from a central part 3 covered with a lubricant put in between a sleeve 4 and strand 2 and end portions 5 in uncovered condition. In the central part of each strand 2, a partial access to the part is made available by a slot 6 provided in the lower part of the floor material 1. After the floor material 1 is installed, the prestress is relieved by the slot 6. This allows excavating a ditch with cast wall constructing techniques.

Title: Tester for vehicle
Inventor: HIRANO BUNYA
IPC: G01M17/00
Filed: 1983-02-07
Abstract: PURPOSE:To shorten testing time of a device for testing the constant position stopping function of an automatic operation device for a vehicle by predetermining the distance of the speed collating point of a constant position stopping pattern (the position where a stop command is applied) via a distance counter in the tester. CONSTITUTION:When a ground element reception signal 13 is turned ON and a start command 11 is turned ON, a signal of a constant speed oscillator 14 is applied to distance counters 20a-20e and an automatic operation device 2. In the device 2, constant position stopping (TASC) patterns K0-KC decrease in response to the signal from the oscillator 14. The counter 20a outputs a stop command signal when the distance S1 is counted by the number of pulse signals from the oscillator 14. The TASC pattern of the device 2 is stopped at the position of n1 by the stop command signal. A variable oscillator 14 is operated in this state to test the sequence. This operating state is indicated by a power drive brake step indicator 19. When the command 11 is again turned ON, the TASC pattern starts advancing from the position of n1.

Title: Character pattern generating system
Inventor: YOKOYAMA AKIMICHI
IPC: G09G5/24
Filed: 1989-01-31
Abstract: PURPOSE:To reduce the data volume by setting circles which have centers at points set at intervals on vector data indicating the skeleton of each picture and have radiuses determined by attribute data and defining the line, which is formed by connecting points of these circles intersecting the advance direction of the vector at right angles, and a contour to generate a character pattern. CONSTITUTION:Circles are set which have centers at points set at proper intervals on the line determined by vector data indicating the skeleton of each picture and have radiuses obtained as a function of distance from the start point of this vector. The line connecting points of these circles intersecting the advance direction of the vector at right angles is defined as the contour to generate a character pattern. Thus, the quantity of stored data is reduced to a half in comparison with the technique where all contours around the character pattern are stored as vectors and the contour line vector font is used.
