Abstract: PURPOSE:To record and reproduce information at a high SN ratio without scratch and warp, by overlapping oppositely an information recording film on the 1st reflecting film coated on the surface of a base and the 2nd reflecting film coated on the surface of a transparent base. CONSTITUTION:A synthetic resin adhesives having transparency at a wavelength region of a laser light for information recording and reproduction, e.g., an ultraviolet ray curing acrylic resin liquid, is coated on the 2nd reflecting film 5 with a spinner, this is overlapped on an inormation recording film 4 and ultraviolet rays are irradiated 9 from the side of the transparent base 6. Then, the surface of the reflecting film 5 of the transparent base 6 and the surface of the recording film 4 of the base 1 are overlapped and fixed in this way. In irradiating a laser light 7 on the 2nd reflecting film 5 or the information recording film 4 through the transparent base 6, there is a difference in an amount of reflecting light depending on whether the laser beam irradiating position exists on the 2nd reflecting film 5 or the information recording film 4, and this difference is taken as a track control signal of the recorded and reproduced laser beam, the laser beam is controlled so as to be irradiated on the information recording film 4 at all times.

Title: Rust prevention container for feedwater
Inventor: MINESHIMA MAKOTO
IPC: B65D90/00
Filed: 1989-04-10
Abstract: PURPOSE:To measure the amount of rust preventives filled in a container in order to attain the constancy of the concentration by setting the pole strips of different heights in rust preventives filling positions and counting the number at its end visible through a viewing window. CONSTITUTION:Water is introduced from a water service pipe through a water receiving pipe 1 into a rust preventives tank 2. The water dissolves the rust preventives 3 and the resulting solution is sent through a chemical receiving net 4 and then through a water feed pipe 5 into the water service pie. In doing so, an aqueous solution of the rust preventives at a predetermined concentration prevents the occurrence of red rust in the water service pipe. To maintain a constant content of the rust preventives, it is necessary to invariably keep the amount of the rust preventives 3 constant. Therefore, a main in charge watches pole strips 7 through a viewing window 6 from time to time to count their numbers and checks for the remaining amount of the chemical 3 and, if short on the amount, he replenishes it. In this way, the concentration can be kept constant.

Abstract: PURPOSE:To eliminate the need for decision of the checking result of correctness of the read data on the timer value that is carried out by a microprogram and to improve the timer reading performance by reading out the the value of a reading register after the higher rank words of a timer are read. CONSTITUTION:A timer 1, a selector 2, a register 7 and an adder 10 are stored in an LSL'A', and the registers 3 and 4 are stored in an LSI'B' respectively. The timer 1 consists of 8 bytes, and the adder 10 counts up the value of the timer 1 in response to an updating pulse of 1 microsecond. Then the register 7 always reads the lower 4 bytes out of the timer 1, and the selector 2 selects the higher 4 bytes of the timer 1 and the value of the register 7 under the control of a microprogram. Thus the register 7 temporarily reads the lower or higher 4 bytes out of the timer 1, and the higher or lower 4 bytes of the timer 1 and the value of the register 7 are continuously read out and sent to both registers 3 and 4.
