By installing one or more water-resistant ultraviolet ray generators 13 that radiate mainly ultraviolet rays having wave length of 380 nm or less to stagnant areas of the circulated cooling water, a growth of microbes can be controlled because of the ultraviolet rays that are radiated to the areas where the microbes can potentially grow and stay in the stagnant areas of the cooling water. In order to expose the entire interior where the growth of microbes can form to the radiation, the water-resistant ultraviolet rays generator 13 is installed at suitable locations above and under the surface of the cooling water. The water-resistant ultraviolet rays generator 13 has on its quartz glass cover a wiping mechanism 14 for continuous or intermittent cleaning.

Title: Multiplexer
Inventor: TOKITSUNE FUJIO
IPC: H04N7/08
Filed: 1995-06-21
Abstract: PURPOSE: To easily and surely multiplex asynchronous serial data by discriminating the coincidence/non-coincidence of a logical level at the timing of continuous edges and setting the timing of a latch based on this result while the edge of a reference signal, whose frequency is double as high as the clock frequency of serial data, is defined as a reference. CONSTITUTION: In latch circuits 29, 30, 35 and 36 by using the reference signal as the reference, latch digital video signals DV1 and DV2 are successively latched by position information extracting circuits 12 and 13. Thus, the logical levels of DV1 and DV2 are successively and cyclically detected at the timing of respective edges of a master clock MCK whose clock cycle is 1/2 as short as the clock cycle of digital video signals DV1 and DV2. Further, the position information extracting circuits 12 and 13 discriminate the matching/mismatching of the logical level corresponding to the continuous edges among these detected logical levels while using AND circuits 31 and 37.

Title: Cassette tape of magnetic recording device
Inventor: KATOU YOSHITSUGU
IPC: G11B23/07
Filed: 1983-09-26
Abstract: PURPOSE:To foresee the timing, when a joint passes on a head, with the output of a reflective sensor to prevent error of data processing by making lengths of an adhesive tape and a sensing tape different from each other to distinguish detection of the adhesive tape and that of the sensing tape from each other. CONSTITUTION:A capstan 15 is rotated to bring a magnetic tape 7 into contact with a magnetic head 13 while running the magnetic tape 7, and in this state, the read or write data processing is performed. Since an adhesive tape 19 and a sensing tape 20 stuck to the magnetic tape 7 pass the front of a reflective sensor 17, the reflective sensor 17 detects the sensing tape 20 to output a relatively long time and detects the adhesive tape 19 to output a short time just after detection of the sensing tape 20. These two outputs are distinguished from each other by the length of time, and consequently, the state where a joint 18 approaches the magnetic head 13 is foreseen by the output which is obtained when the reflective sensor 17 detects the sensing tape 20.
