IPC: G03B27/34
Filed: 1981-04-30
Abstract: PURPOSE:To make magnifications continuously variable with relatively simple construction by using a projecting lens of a fixed focus without using any zoom lens. CONSTITUTION:A microfilm 3 illuminated by a lamp 1 is projected to a photosensitive drum 9 by a projecting lens 4 of a fixed focus and mirrors 5-8. The mirrors 6, 7 are disposed mutually at right angles, and reflect the optical axes of the projection light incident thereto in such a way as to be reversed in directions in the same direction. The mirrors 6, 7 form an optical system 8 for adjusting optical path length, are held integrally in a mirror holder 9' and are moved by a micromotor 12. Further, the lens 4 is moved on the optical axis of the projection light by a micromotor 14. The lens 4 is made interchangeable with lenses 4' of different fixed focuses. If the machine is constituted in this way, magnifications are varied continuously with the relatively simple construction by using the projecting lens of a fixed focus.

Title: Thermal recording material
IPC: B41M5/30
Filed: 1992-03-25
Abstract: PURPOSE:To enhance preservability and transparency by adding a blend of coloring agent and color developer with at least, one type of binder in a state of fine particles to a binder layer and form a thermally sensitive layer. CONSTITUTION:Leuco dye such as xanthene which has a partial skeleton of lactone is used as a coloring agent and a chemical compound, especially with a melting point of 200 deg.C max. such as a phenol compound is used as a color developer. Next, the coloring agent or the color developer is dissolved in a solvent with a binder of acrylic resin, then this solution is sprayed and dried to obtain a blend of fine particle. Further, the blend is added to a thermally sensitive layer binder layer which has a difference in the index of refraction of 0.1 max. from the index of refraction of the fine particle, and the thermally sensitive layer is formed on a support such as a transparent polymer film. In this case, the mixture ratio of the binder for the coloring agent or the color developer has only to be an amount enough to inhibit the crystallization of the coloring agent and the color developer. In addition, the larger percentage of the coloring agent and the color developer is preferred. Further, the preferred size of the fine particle is 20mum max. and the fine particle should be amorphous.

Title: Intake-air heating device in internal-combustion engine
Inventor: YOKOYAMA JIYUNICHI
IPC: F02M31/04
Filed: 1982-04-23
Abstract: PURPOSE:To enable a desired power to be ensured in a device in which intake- air is heated through heat-exchange with engine cooling water, by decreasing or stopping the flow of cooling water for heating intake-air in a high load operating range so that the efficiency of air charging is prevented from decreasing. CONSTITUTION:In the partial load operating range of an engine, a pin 15 on a rod 14, which slides in a slit 17, does not rotate a bellcrank 16 even if a throttle lever 13 is rotated counter-clockwise from a position indicated by the solid line, by the valve opening operation of a throttle valve 11, and therefore, a valve 10 disposed in an intake-air passage 7 is held in its full open position. Accordingly, intake-air in the intake-air passage 7 is heated by cooling water through the wall 7A of the intake-air passage 7, and therefore, the evaporation of fuel is promoted. Then, when the high load operating range at which the throttle valve 11 is nearly fully opened, is established, the open degree of the valve 10 is decreased by means of a pin 18 and a slit lever 19 since the rod 14 and the pin 15 are abutted against the right end of the slit 17 so that the bellcrank 16 is rotated, thereby the heating of intake-air is decreased or stopped.

Abstract: PURPOSE:To reduce a required arithmetic operation quantity with high speed tracking performance by deciding a survival path based on a path metric of a time relevant integrated value of square of a difference between a reception signal and an inner product between N-dimension vectors of sampled reception signals and N-dimension vectors. CONSTITUTION:An arithmetic operation control section 6 recognizes m'(k-1) sets of survival paths from one branch m/m' in all entry branches to a noted state mk by referencing a memory 3. Then last (N+L) symbols are extracted from a series to the tail end of which a code specifying the branch m/m' is added as an object transmission series and a relevant N-dimension vector gm/m'k is read from a memory 1. From a memory 2, gammak-1, gammak are read and from the memory 3, path metrics Pk-1,m' are read and the calculation is implemented according to equations I-III. the Pk, m/m' of all the entry branches to the state mk are calculated to select a branch of a minimum path metric. The branch code is added to the survival path of the selected state m'(k-1) to adopt the survival path in the state mk and the minimum value as the path metric Pk, m thereby revising the memory 3.

Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To readily designate the range of a transmission destination, meet the increase of the functional information of indoor machines and identify contents when an abnormality occurs by dividing the specified number of groups of the indoor machines into blocks. SOLUTION: In a centralized controller 1, values inputted by operating ten keys and a determining switch are stored as block formation end number in a storing element. For instance, in the case of an air conditioner block 6A, a plurality of groups from a block start group 5B to an end group 5C are formed into a block. When there is no input by the determining switch, an input depending on the operation of ten keys is waited for. When there is an input arbitrary groups enter a block formation mode. Then, values inputted by operating the ten keys are stored in the storing element as block formation numbers until the input by the operation determining switch is supplied. For example, in the case of an air conditioner block 6B, groups 5E and 5I are formed into a block as arbitrary groups.
