Inventor: UDAGAWA ISAO
IPC: G06F13/00
Filed: 1991-07-15
Abstract: PURPOSE:To surely control between apparatus connected by optical links by a simple method by using a part of each two-point RAM as a sequence counter.

When final data are stored in the RAMs 12, 22 and the sequence counters add '1' to their contents, an interruption is generated and data for one cycle are synchronized at the timing of the interruption. Thereby an interruption is generated in the RAMs 12, 22 in each updating of one cycle and the data of one cycle are synchronized to receive the newest data. Thus plural apparatuses connected through the optical links can surely be controlled.

Title: Fluorescent-dot planimeter
Inventor: ROMANO DAVID J
IPC: B41F31/02
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To obtain a fluorescent-dot planimeter by which the area of a halftone dot on a printing plate is measured precisely, by a method wherein light at a wavelength in a first range is supplied to the printing plate from a light source, the printing plate is exposed, light at a wavelength in a second higher range is radiated from the printing plate and the light is measured. SOLUTION: A light source 16 supplies light λ, in a first wavelength range, whose energy is sufficient to such an extent that specific molecules in an emulsion 14 remaining on the surface of a printing plate 12 radiate light λ' in a second higher wavelength range. The light λ' which is radiated from the part of the printing plate 12 is separated so as to be detected by a sensor 18. The output of the sensor 18 is supplied to a processor 20, and the percentage of an area inside the part of the printing plate 12 is covered with halftone dots, i.e., a percentage cover rate, is computed. When a dot-area measured output is unsatisfactory, various plate manufacturing variables such as an exposure, a focus and a pulse-width modulation are adjusted so as to be optimized.

Title: Manufacture of polyolefin cellular body
Inventor: ITO HIROO
IPC: B29C39/44
Filed: 1984-08-22
Abstract: PURPOSE:To make it possible to obtain a high expansion ratio of 40 or more, by removing a molded item from molds with the foaming agent therein still remaining undecomposed, and heating this intermediate item under normal pressures. CONSTITUTION:A foaming agent and a crosslinking agent are added to a polyolefin, the mixture is kneaded, and is loaded into molds, the molds are closed under pressure, the mixture is heated for a certain period to decompose the crosslinking agent partially and the foaming agent 0-15%, and the pressure is released with the molds heated, so that an intermediate item that has 85% or more of the foaming agent still undecomposed is molded. Then the intermediate item is heated to a temperature under normal pressures so that the undecomposed foaming agent and the crosslinking agent may be decomposed thereby producing a low-density polyolefin cellular body having an expansion ratio of 40 or more. The reason why the degree of decomposition of the foaming agent in the first stage is restricted to 0-15% is that when the expansion ratio is 40 or more, the crosslinking agent becomes excess in the first stage where the expansion ratio is 6 or more and a satisfactory cellular body would not be produced.

Title: Memory access controller
Inventor: TAKAHASHI ATSUSHI
IPC: G06F12/06
Filed: 1989-07-05
Abstract: PURPOSE:To improve the processing performance of a memory access request by reading out a main storage after adding the request address difference between the preceding and subsequent reading requests to the reading address of the preceding memory reading request. CONSTITUTION:When an address control part 10C judges that a subsequent request address is included in the block address of a preceding request, an address count-up circuit 10D counts up the difference between the preceding and subsequent addresses to the addresses equal to one block of a preceding memory access request set to a memory address register 10A. Then a main storage 102 is read out with the output of a memory address count-up register 10E including the block addresses of both preceding and subsequent memory access requests. In this case, the execution of an access is suppressed for the subsequent memory access request to the storage 102 via a main storage access suppressing part 10B. Thus, the number of times of the access is decreased to the storage 102 and the processing performance of the memory access request is improved.
