Title: Pulse coder with delay correction
Inventor: SAKANO TETSURO
IPC: G01D5/36
Filed: 1990-11-06
Abstract: PURPOSE:To prevent the vibration of a detecting position caused by delay correction and the discontinuity of an output position by using required coefficients, and correcting a pulse train corresponding to the output angle of a moving position. CONSTITUTION:The pulse train of the output of moving positions corresponding to the detected rotating angles which are changed with a rotating speed is formed with an optical or magnetic sensor 10 and an input circuit 11. The pulse train is inputted into a microcomputer 12. The rotating speed for every specified period is detected. When the detected speed is the low speed which is less than the first specified value, 0 is obtained. When the rotating speed is the high speed which is higher than the second specified value, 1 is obtained. In between the first and second preset values, the correcting coefficient which is changed from 0 to 1 in response to the detecting speed is obtained. The delay correcting value is computed by the multiplication of the above described coefficients, the detecting speed in the previous period and the specified period. The detected moving position is corrected. The vibration of the detecting position caused by the delay correction is prevented by this correcting method, and the occurrence of the discontinuity of the output position is also prevented.

Abstract: PURPOSE:To obtain the optical information recording medium of a veneer structure having high sensitivity and high C/N by providing an under coating layer consisting of a thermally softening material between a substrate and a recording layer and selectively setting the refractive indices and film thicknesses of the under coating layer and the recording layer. CONSTITUTION:The under coating layer 7 consisting of the thermally softening material is provided between the substrate 2 and the recording layer 3. The layer 7 is set at the refractive index smaller than the refractive index of the substrate 2 and at the film thickness at which the max. reflectivity is obtd. near the wavelength of recording and reproducing light. The layer 3 is set at the refractive index larger than the refractive index of the layer 7 and smaller than the refractive index of a protective film 6 and at the film thickness at which the max. reflectivity is obtd. near the wavelength of the recording and reproducing light. The reflectivity of the layer 3 is, therefore, improved and the deterioration by the reproducing light is decreased. Since the thermally softening material is used for the layer 7, the recording is executed by the deformation formed at the boundary of the layers 3, 7. Multireflection interferences are thus broken and the contrast and the C/N are improved. The recording medium having the high sensitivity and the simple structure is obtd. in this way.

Title: Steam continuous generator
Inventor: IKEDA KUNIAKI
IPC: F22D5/26
Filed: 1987-11-27
Abstract: PURPOSE: To rapidly replenish water from a replenish tank and hence smooth continuous operation, by constructing the operation such that closing timing of an opened pressure homogenizing opening/closing valve is set to be timing when a temperature sensor detects re-rising of water after lowering temperature in accordance with water supply by gravity. CONSTITUTION: When a uniform pressure opening/closing valve 11 is opened, steam is introduced into a water supply tank 4, and hence a pressure level is the same as that in a can structure 1, whereby water from a water supply tank 4 is supplied with the aid of gravity through water supply pipes 4a, 4b. Temperature detected by a temperature sensor 7 provided on a water supply pipe 4a is once lowered owing to the water supply. When the water supply is completed, the temperature detected by the temperature sensor 7 is again raised. When the detected temperature is again raised, a controller 14 closes the uniform pressure opening/closing valve 11. Once the uniform pressure opening/closing valve 11 is closed, steam in the water supply tank 4 is condensed owing to natural cooling into reduced pressure, so that the water from a water replenish tank 12 in an atmospheric condition sucked into the water supply tank 4 to a full level.
