Title: Display device
Inventor: YAMAMOTO HIROAKI
IPC: G09G3/02
Filed: 1990-02-07
Abstract: PURPOSE:To reduce the load on the driving of a beam scanning galvanomirror and to make operation noise small by driving a movable reflecting mirror normally and reversely alteinately at intervals of one scanning line. CONSTITUTION:A scan converter 28 is added between a laser beam emission device 26 and its video signal input terminal 30 and the scan converter 28 is equipped with a dual-port memory. The memory is divided into two blocks, which are each stored with a video signal on one scanning line. Data are read out normally and reversely alteinately at intervals of one scanning line and sent to the laser beam emission device 26 and converted into a laser beam 24 with corresponding intensity. Horizontal and vertical deflection galvanomirrors 16 and 18 are driven by driving devices 14 and 20 and put in horizontal and vertical oscillatory motion, and the horizontal deflection galvanomirror 16 is driven at a constant speed except at a direction change point of time. In this case, the movable reflecting mirror is only changed in scanning direction at the left and right ends of a screen. Consequently, the driving devices are reduced in size and the operation noise is made small.

Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To perform energy conservation by monitoring operating state of a chilled water type refrigerator and automatically stopping or restarting a compressor motor according to a chilled water inlet temperature. SOLUTION: Whether the chilled water type refrigerator is faulted or not even if a compressor motor is stopped at timing based on an operating state confirmed by a chilled water type refrigerator operation monitor sensor 22 if chilled water inlet temperature measured by a chilled water inlet temperature sensor 13 is a predetermined compressor motor stop temperature or lower is calculated by a compressor motor operation controller 20. When small fault is output from a calculated result, a compressor motor electromagnetic switch 19 is opened to automatically stop a compressor 1. And, if the chilled water inlet temperature is a predetermined compressor motor operation temperature starting temperature or higher, whether the refrigerator is not faulted or not even if an operation of the motor is started is calculated by the controller 20.  If small fault is output from the calculated result, the switch 19 is closed to restart the operation.

Title: Heat-collecting plate for solar heater
Inventor: TSUKAMOTO AKIRA
IPC: F24S10/70
Filed: 1981-02-28
Abstract: PURPOSE:To raise the durability and stability of a heat-collecting plate for solar heaters, consisting of an inner layer and an outer layer, by forming the inner layer of a resin material having a higher fluidity at low temperatures than that of a resin material constituting the outer layer. CONSTITUTION:In a heat-collecting plate consisting of an inner layer B and an outer layer A for solar heaters, the inner layer B is formed from a resin material (e.g., low-density polyethylene) having a higher fluidity at low temperatures than that of a resin material (e.g., high-density polyethylene) constituting the outer layer A. In sort, since the inner layer has a lower viscosity than that of the outer layer at the same temperatures, the generation of pinholes, etc., in the inner layer can be lessened and also the amount of redidual stress due to compression can be reduced. Furthermore, stress or deformation resulting from the freezing of the heat-collecting plate can also be relaxed. Also, the use of high- density polyethylene in the outer layer enables the regidity at high temperatures (60-90 deg.C) to be retained. Thus, the heat stability of the heat-collecting plate when in use can be maintained and therefore, the heat-collecting plate having a high stability for a long period of time can be obtained.

CONSTITUTION:Visible light is irradiated by switching on a light source lamp 1 of projecting section A and its radiation angle is set by an optical lens mechanism 2. Visible light passes through an information sheet B at a specified radiation angle and then the contents of the sheet B is projected onto an imaging section C such as a worktable 5 or a printed board 4. The position of a substrate 4 and the height of the optical lens mechanism 2 of the projecting section A or the sheet B are adjusted. An operator prepares parts, line materials, etc., according to the instruction of operational information 6 which is projected onto the worktable 5. When change information is projected, operation is conducted according to it. Blink controlling section 11 is attached to the light source section A and operator's attention is called by blinking the contents of operational information projected onto the imaging section C. In this way, possibilities to lose track of operation point is eliminated and operating efficiency is substantially improved.
