Title: Surface painting method for pressed cement roof tile
Inventor: MATAYOSHI MORIYOSHI
IPC: B05D1/02
Filed: 1986-03-10
Abstract: PURPOSE:To suppress the whiting of a coated film and to prevent the exfoliation of the coated film by spraying a mixture composed of styrene/butadiene synthetic rubber, carboxylic acid, pigment and water to a slate surface. CONSTITUTION:The mixture prepd. by mixing the styrene/butadiene synthetic rubber as a binder with the carboxylic acid and pigment and adjusting the viscosity with kneading water is sprayed onto the slate surface 4 consisting of cement to form the coated film 5 on the slat surface in a surface painting method for a pressed cement roof tile. Then, the salts formed by a hydration reaction bleeding onto the surface from the slate inside are neutralized by reacting with the carboxylic acid and form an insoluble colloidal material 8 gradually from the slate surface toward the slate inside. The material 8 closes the mortar and capillaries and suppresses the whiting.

Title: Moistening device
Inventor: IWAHASHI HIROSHI
IPC: F24F6/04
Filed: 1981-04-08
Abstract: PURPOSE:To visually appeal a moistening effect, by providing 2 temperature-sensitive elements within a moistening device to detect the dry-bulb and wet-bulb temperatures to calculate and display the relative humidity. CONSTITUTION:With the operation of a motor 4, a fan 5 also rotates. Thus the air in a chamber flows into a moistening device 1 through a suction port 3. The dry-bulb temperature is measured for a temperature-sensitive element 16 since the air flows the area near the element 16. The sucked air passes through a filter 15 and is exhausted to the outside through an exhaust port 13, and the evaporation heat is deprived when passing through the filter 15. As a result, the temperature within the chamber is lowered. This drop of temperature is detected by a temperature-sensitive element 17 attached to the filter 15 to obtain a wet- bulb temperature. The values obtained through the elements 16 and 17 are calculated at a calculating part 18 to obtain the relative humidity. This humidity is displayed at a display part 19.

Abstract: PURPOSE:To obtain an optical coherent equipment with a simple configuration by dividing a short optical pulse train into laser beams whose optical frequencies differ from each other, adopting one of them for a reference light, and using at least one beam other than the reference light and modulating it into a signal light, sending them simultaneously to an optical transmission line and allowing a receiver to use the received reference light as a local oscillation light and to detect the signal light. CONSTITUTION:A short optical pulse outputted from a semiconductor mode synchronization laser 11 is branched by a branching filter 12, from which laser beams with optical frequencies of f1-fm are obtained. For example, let a repetition period of the mode synchronization laser 11 be 2GHz, the frequency interval of the optical frequencies f1-fm becomes 2GHz. The optical frequency f1 among the laser beams with the optical frequencies of f1-fm is defined as a reference light and the other laser beams are modulated respectively by an optical modulator 14 to obtain signal lights. The receiver inputs the received lights to a photodetector 31 in a lump. In this case, the reference light not modulated works as a local oscillation light. Thus, the photodetector 34 observes (m-1) kinds of signals whose pitch is 2GHz.
