Title: Louver device
Inventor: KONDOU KIYOSHI
IPC: F24F13/15
Filed: 1981-10-09
Abstract: PURPOSE:To enable to change the direction of a louver automatically through detection  of the temperature of air, by disposing louver elements in an air passage for controlling the direction of air flow, and connecting a spring made of a shape memory alloy  for applying a force turning the louver elements in one direction. CONSTITUTION:Louver elements 1 are disposed in an air passage 6 for controlling the  direction of air flow, and a spring 4 made of a shape memory alloy is connected to  the louver elements 1 so as to apply a force turning them in one direction. Further, a  weight 5 is connected to the louver elements 1 for applying a force turning the louver  elements 1 in the opposite direction. Here, the temperature at which deformation of  the shape memory alloy is caused is selected at an intermediate point between the temperature of space-cooling air and that of space-heating air. In space-cooling operation,  the spring 4 is expanded by the weight 5 since the temperature of air is low and resultantly the tensile force of the spring 4 is weak. Thus, the louver elements 1 are  turned upward. In space-heating operation, on the other hand, the spring 4 causes reverse deformation and is contracted against the force of the weight 5, so that the  louver elements 1 are turned downward. Thus, the direction of the louver elements 1  can be changed automatically through detection of the temperature of air at the time  of space-cooling and space-heating operation.

IPC: B65F1/14
Filed: 1994-07-13
Abstract: PURPOSE:To eliminate the clinging of garbage to a shaft, in a garbage treatment apparatus wherein the interior of a treatment tank is stirred by the stirring blades attached to the shaft, by providing a culture bed material storage part on the outer peripheral surface of the shaft. CONSTITUTION:In a stirring means 15 stirring the garbage culture bed material 23 in a garbage treatment tank 12, a recessed part (culture bed material storage part) 19 is provided on the shaft 17 rotating stirring blades 18 so as to extend in the axial direction of the shaft. When garbage is thrown in the garbage treatment tank 12 from a throwing-in port 12a and a switch is turned on, an electric motor 16 rotates the stirring blades 18 through the shaft 17 and the culture bed material 23 and garbage are stirred to accelerate the microbiological decomposition of garbage. At this time, even when fibrous long garbage clings to the shaft 17, the culture bed material 23 enters the recessed part 19 and, therefore, garbage can also come into contact with bacteria from the inside thereof and microbiological decomposition is devanced to release the clinging of garbage to effectively perform the decomposition of garbage by bacteria.

Title: Plane image stereoscopic viewing and visual acuity correcting frame
Inventor: OKINO HIROYUKI
IPC: G02B27/22
Filed: 1999-05-01
Abstract: PROBLEM TO BE SOLVED: To provide a frame which does not apply any special color processing to plane images in the state of naked eyes, is light in weight, enables plural people to appreciate stereoscopic images without requiring a television to be exclusively used and enable users to strengthen and train the optic nerves by determining the visual field point at separate times and smoothly concentrating the visual fields. SOLUTION: The size between the right and left pupils is mutually matched by adjusting the angle or width of respective opening/closing plates 2 of right and left center portions 1 around a nose pad 4 existing at the front portion of the frame. The visual fields are laterally sorted in such a manner that the right eye views the right visual field of the plane images (books, photographic albums, televisions, movie screens, etc.), and the left side views the left visual field. The plane images are stereoscopically viewed by utilizing the parallax between the two eyes. The user peeps remote from holes 8 bored at the opening/ closing plates 2, adjusts the size between right and left pupils and the height of them determines the visual field point (an image or character), smoothly concentrates the visual field and intensifies and trains the optic nerves.

Filed: 1983-09-01
Abstract: PURPOSE:To read out the digital signals of a program, etc. with use of an existing digital audio disk by providing a buffer memroy for correction of time base variation even for reproduction subdigital data. CONSTITUTION:A clock synchronizing with a frame synchronizing signal which is detected from a reproduction signal obtained from a frame synchronizing detection circuit 11 is produced by an RAM controller 15. Then a reproduction main digital audio signal is written to an RAM16. The read-out of the RAM16 is controlled by a clock delivered from a reference oscillator incorporated to the controller 15. Thus the time base variation of the main audio digital signal is corrected. While a buffer memory 13 for reproduction subdigital signal is provided and controlled in the same way as the RAM16 to correct the time axis variation of the subdigital signal. Therefore it is possible to read out accurately the digital data other than a program and the audio signal by means of an existing digital autio disk.

Filed: 1987-06-29
Abstract: PURPOSE:To improve detecting accuracy and to improve response, by integrating the output voltage of a detection circuit, which detects the level of a signal that is generated periodically, sampling and holding the output voltage at a fixed timing based on a signal generation period, and resetting an integration circuit immediately after the holding. CONSTITUTION:When a periodic video signal Ei is inputted into a level detection circuit 7, the video signal Ei is detected with a diode 4. A capacitor 6 is charged with the detected voltage. Even if the video signal has reached a peak level and then the signal is decreased, the charged voltage corresponding to the peak level of the input signal is maintained in the capacitor 6 owing to the blocking of the discharge of the capacitor 6 with the diode 4. Said charged voltage is charged into a capacitor 14 and maintained by way of a FET 11. A reset pulse is imparted to a reset circuit 9 at a starting timing Tr of horizontal blanking. A FET 15 is turned ON through a diode 17. The maintained signal charge is discharged and reset. The charge in the capacitor 6 becomes 0V. Then the next charging is performed.
