Title: Microcomputer
Inventor: OSAWA HIROSHI
IPC: G06F15/78
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To immediately compare and examine program contents that is written by a maker at the time of shipping with program contents that is altered by a user by writing history data of which program data is stored in 1st volatile memory on 2nd volatile memory. SOLUTION: When an one chip microcomputer is shipped, history of which program data is stored on flash memory 1 is written on flash memory 6. Thereby, because the maker immediately compares and examines the program contents that is shipped by the maker with the program contents that is altered by the user even if a user alters the program contents of the memory 1 intentionally, responsibility is prevented from being wickedly shifted by the user. Further, the setting of a history mode is performed by using an external tester and therefore, it is impossible for the user to rewrite history content of the memory 6.

Title: Scanning probe microscope
Inventor: MORIMOTO TAKASHI
IPC: G01N37/00
Filed: 1996-08-16
Abstract: PROBLEM TO BE SOLVED: To make compatible the reduction of a ratio of an error signal with the enhancement of the frequency response of control by providing a Z-axis piezoelectric element on a cantilever holding part in the adjustment of the distance between a probe and a sample and reflecting the laser beam from a laser beam source by the rear surface of a cantilever through the cantilever holding part to detect the same by a photodetector. SOLUTION: A Z-axis piezoelectric element 12 is bent and the angle and position of a cantilever 11 and a reflecting surface 12a are changed but, since the angle formed by the rear surface of the cantilever 11 and the reflecting surface 12a is not changed to be held to 90 deg.C, the angle of laser beam incident on a photodetector 15 is held in parallel to the emitted beam from the laser beam source 14. As a result, the extension of displacement by an optical lever does not act and only the error component due to the parallel movement of laser beam is detected and a ratio of an error signal is reduced. Since the ratio of the error signal does not depend on the length of the Z-axis piezoelectric element 12 being the holding part of the cantilever 11, the size of the holding part, that is, the Zaxis piezoelectric element can be reduced and the response frequency of control can be enhanced.

Title: Method of light-weight prepacked concrete construction
Inventor: BESSHO TOMOHIRO
IPC: B28B1/50
Filed: 1987-09-21
Abstract: PURPOSE: To enhance adhering strength between mortar and artificial lightweight aggregates and making them together in one united body by using artificial lightweight aggregates having irregular polygons in external shapes extruded and formed through wire gauze base of deformed openings. CONSTITUTION: Artificial lightweight aggregates 1 having external shapes such as regular quadrangle, regular hexagon, star shape or the like are produced by extrusion forming through deformed openings such as regular quadrangle, regular hexagon, star shape or the like formed to wire gauze bases of an extrusion molding machine by using clay as principal raw material. For example, when voids between the steel cores of a marine platform are filled up with regular hexagon-shaped artificial aggregate 1 and mortar is poured, the mortar invades so as to cover the surroundings of the aggregate 1 thereby keeping larger contact surface areas with the aggregate 1 and makes mutual adhesion greater.
