Title: Nuclear reactor container
Inventor: TSUTAGAWA MASAHIRO
IPC: G21C9/00
Filed: 1988-02-10
Abstract: PURPOSE:To suppress increases in concentration of the hydrogen and oxygen in a lower dry well by providing a coupling pipe which links the lower dry well with a pressure suppression chamber and connecting a vacuum break valve to the end part of the coupling pipe on the side of the pressure suppression chamber. CONSTITUTION:If the hydrogen and oxygen in the dry well 9 rises in concentration at the time of a virtual accident such as the breakage, etc., of the main vapor pipe 4 in the nuclear reactor container 1, pressure drops are caused in dry wells 8 and 9 by flowing out emergency reactor core cooling water or operating a combustible gas concentration controller 19, and consequently there is differential pressure among the dry wells 8 and 9 and pressure suppression chamber 6. This differential pressure operates a vacuum break valve 21b to send an atmosphere where the hydrogen and oxygen in the pressure suppression chamber 6 are low in concentration into the dry well 9 through the breakage valve 21b and a communicating pipe 21a. After excellent mixing is obtained, the atmosphere in the dry well 9 is sent to the dry well 8 through a communication port 10 with the differential pressure between the dry wells 9 and 8, and consequently the concentration rises of the hydrogen and oxygen in the dry well 9 are suppressed.

Title: Remaining quantity detecting device for cassette tape
Inventor: KINOSHITA MASAKATSU
IPC: G11B27/17
Filed: 1988-02-10
Abstract: PURPOSE:To exactly detect a tape remaining time by obtaining the tape remaining time regardless of the thickness of a tape and averaging this time. CONSTITUTION:A period TN in an N-th revolution of a supplying reel is detected. Then, a hub diameter is put as (r) and a tape sending speed is put as (v). Then, a tape remaining time tN is calculated by an expression I. After that, an arbitrary integer number, which satisfies 1<=M<=N, is put as M and a passing time until the supplying reel executes N-revolution is put as SN. Then, an averaged tape remaining time tN1 is calculated by an expression II. Thus, since a thickness theta of the tape is not included in the expression, a dispersion error due to the thickness theta of the tape is not generated. Since the tape remaining time tN1, which averages the calculated tape remaining time tN, is calculated, the error of the rattle, etc., of the hub can be suppressed. Thus, the exact tape remaining time can be obtained.
