Title: Spring type safety valve
Inventor: MASUDA NOBUTERU
IPC: F16K17/04
Filed: 1985-02-13
Abstract: PURPOSE:To prevent a preleak by providing a valve body pressing supplementary device which has a great spring constant and a low strength in comparison with those of a valve body pressing spring. CONSTITUTION:A bolt holder 9 is stuck to a valve box 10. A valve body pressing metal 7 is pressed by a valve rod 1 via a valve body pressure bolt 8 and a valve body 2 is pressed against a valve seat 4 via a valve rod 1 together with a cylindrical coiled spring 3. The valve body pressing metal 7 is manufactured from a material having a low resiliency and has a V-shaped notch 11 in the opposite position of the contact point with the valve rod 1. Said metal 7 has higher spring constant than the cylindrical coiled spring 3 and a lower strength than the cylindrical coiled spring 3. The valve body pressing metal 7 thereby prevents both the valve rod 1 and the valve body 2 from being displaced before fluid pressure at the primary side reaches a preset pressure of the valve 2, hence preventing a preleak.

Title: Method for registering printed matter
Inventor: YAMANAKA YASUO
IPC: B41F33/14
Filed: 1987-02-04
Abstract: PURPOSE:To facilitate recognition of shifting of registration, by printing solid printing sections having a similar shape while overlapping sequentially, then observing the overlapped state. CONSTITUTION:A register mark 2 of second color having a shape similar to that of a register mark 1 of first color is solid printed onto the solid printed register mark 1 of first color while being overlapped. Furthermore, register marks 3, 4, 5 of third, fourth, fifth colors having a shape similar to that of the register mark 1 and sequentially decreasing area are solid printed sequentially while overlapping each other. Correct registration is recognized by checking whether circumferential portion of a register mark formed in a layer immediately under a register mark of each printing color appears uniformly at four sides. With such a method, shifting of respective register mark is represented as a clear frame section which can be recognized easily.

IPC: G07G1/12
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To safely and securely transmit necessary information from a car- rental office to a return office. SOLUTION: At the car-rental office, information needed for a rental car which is inputted through an information input means is converted by a code converting means into a two-dimensional code 21. The converted two-dimensional code 21 is printed on a printing medium 30 under the driving control of a printer by a code printing means. This printing medium 30 is carried with the rental car. At the return office, the user reads the two-dimensional code 21 printed on the printing medium 30 received at the car rental office by a code read means which performs driving control over a code reader and a code decoder means decodes it to reproduce and input the rental information as it is.  Namely, the printing medium 30 on which the two-dimensional code 21 is printed is an information transmission medium, so the data are never destroyed even in consideration of a special state wherein the temperature in the cabin becomes high. Therefore, the necessary information can safely and securely be transmitted from the rental office to the return office.
