Patent CA-2025808-C (CA)
Title: Automatic follow-up projecting system
Inventor: MIYAMOTO TAKASHI
IPC: G05D3/12
Filed: 1990-09-20
Granted: 1993-08-17
Abstract: ABSTRACT OF THE DISCLOSURE A light (or an infrared ray) emitting member or a reflective (or an infrared ray reflective) medium (something like a reflective tape which reflects light in the caoxial direction when light is applied to it) is mounted at a predetermined position on an object to which an image is projected.  The light emitting member or the reflective medium is caught in the coaxial direction of an image projecting unit by an (infrared ray) image Pick-up means and video signals obtained by the (infrared ray) image pick-up means are binarized in the image processing unit, thereby a high luminous part of the light emitting portion or the reflected portion necessarily coming out on a binary image.  A central value of a primary moment (so called a center of the figure) on the binary image including the high luminous point obtained by the above operation, is calculated on real time, and the calculated data are fed back to an electrically-driven driving portion of the image projecting unit, so that the image may be continually projected at the predetermined position.  The electrically-drive turn table is adapted to automatically control the image projecting direction including the direction of light.  Carrying out a series of the controls described above exactly, the image projecting apparatus projects the image by auto-matically tracking the position of the moving light emitting member or the reflective medium.  Consequently, the image can be continually projected at the predetermined position, automatically tracking the moving object such as an airship or a balloon, so that it can be available as an effective advertizing medium or news medium.

Title: Speech analysis-synthesis method and apparatus therefor
Inventor: HONDA MASAAKI
IPC: G10L19/10
Filed: 1990-10-01
Granted: 1996-07-09
Abstract: An impulse sequence of a pitch frequency is detected from a phase-equalized prediction residual of an input speech signal, and a quasi-periodic impulse sequence is obtained by processing the impulse sequence so that a fluctuation in its pitch frequency is within an allowed limit range.  The magnitudes of the quasi-periodic impulse sequence are so determined as to minimize an error between the waveform of a synthesized speech obtainable by exciting an all-pole filter with the quasi-periodic impulse sequence and the waveform of a phase-equalized speech obtainable by applying the input speech signal to a phase equalizing filter.  Preferably, the quasi-periodic impulse sequence is supplied to the all-pole filter after being applied to a zero filter in which it is given features of the prediction residual of the speech.  Coefficients of the zero filter are also determined so that the error of the waveforms of the synthesized speech and the phase-equalized speech is minimum.

Title: Cap closing member for container opening
Inventor: NOZAWA TAKAMITSU
IPC: B65D41/28
Filed: 1991-03-01
Granted: 2003-02-25
Abstract: Disclosed is a lid closing member for a container opening. The lid closing member is made such that rear surf aces of a main body (1) and a lid (3) having the same cross-sectional shape as the main body are connected to each other by two resilient belt plates (7, 7), i.e. hinge parts.      Each of the resilient belt plates (7, 7) forms a trapezoid, its top sides (7b, 7b) being oppositely faced to each other and connected to the rear surface of lid (3). Each of the resilient belt plates (7, 7) is connected to the rear surface of the main body (1) having a circular cross-section and a rear side surface of the lid (3) having a circular cross-section, thereby the sectional shape crossing at a right angle with the resilient belt plates (7, 7) may form an inverted truncated V-shape. In this way, it is possible to prevent the hinge parts from projecting rearwardly.

Title: Slant plate type compressor with variable capacity control mechanism
Inventor: TAGUCHI YUKIHIKO
IPC: F04B27/08
Filed: 1991-11-08
Granted: 1995-11-07
Abstract: A slant plate type compressor having a capacity or displacement adjusting mechanism includes a housing for a cylinder block provided with a plurality of cylin-ders and a crank chamber.  A piston is slidably fitted within each of the cylinders and is reciprocated by a drive mechanism which includes a slant plate having a surface with an adjustable incline angle. The incline angle of the slant plate, and thus the capacity of the compressor, is controlled according to the pressure differential between the crank chamber and the suction chamber. The pressure in either the crank chamber or the suction chamber is controlled by an externally controlled valve mechanism which is disposed in a passageway linking the crank chamber and the suc-tion chamber. An internally controlled safety valve device prevents an abnormal pressure differential between the crank and suction chambers. The internally con-trolled safety valve device is provided within the externally controlled valve mecha-nism, thereby obtaining an easily manufactured slant plate type compressor having a capacity adjusting mechanism with a safety valve device.

Title: Timed release of water-soluble plant nutrients
Inventor: LUTHRA NARENDER PAL
IPC: C05G3/00
Filed: 1993-06-07
Granted: 2004-04-20
Abstract: Products for the variable controlled release of water soluble agents are disclosed. The products have a core of water soluble agent and a first and second coating. The first coating has a permeability such that the agent can be released at a controlled rate, while the second coating has a relatively low water vapor transmission rate. Variation in the coating thicknesses and coating conditions result in nutrient release profiles which can be tailored to specific plant requirements. After application of the product, release of the agent is negligible, but after a predetermined time, e.g. one month or more, substantial release of the agent from the coated product begins. The product is particularly suitable for delayed, controlled release fertilizers.
