Title: Light source device and projection type display device
Inventor: HAYASHI KEIJI
IPC: F21V7/04
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To restrict the generation of unevenness of color and luminance of a displayed image due to the unevenness of luminance of a discharge tube by forming a light diffusing means for diffusing the light from a light emitting means in a part of a reflecting surface. SOLUTION: In a liquid projector formed of a metal halide discharge tube 11 and a reflector 12, the reflector 12 emits the light, which is formed by the metal halide discharge tube 11, to optical beams 12A in nearly parallel with each other. A reflecting surface forming the reflector 12 is formed with projecting surface areas a1 -a5 as a light diffusing means per each quadrant of a first - a fourth quadrants symmetrically in upper and lower and in right and left. As a result, the light emitted from the tube 11 corresponds to an envelope formed by the reflector 12 and is focused to the shape of nearly parallel beams as a whole, but reflecting angle is different between the light, which is reflected at the center Q, and the light, which is reflected at a peripheral part, in each projecting surfaces a1 -a5 , and the beam 12A is diffused at some degree.  The beam 12A can be thereby deformed at a desirable aspect ratio, and while the unevenness of luminance of the beam 12A due to the unevenness of luminance of a light emitting means can be eliminated.

Filed: 1993-07-28
Abstract: PURPOSE:To prevent erroneous operation which occurs due to rise of temperature and prevent a user from determining a breakdown by a printing device wherein all printings are performed when temperature of a thermal head reaches a first temperature and a normal printing is stopped till below the first temperature when the temperature of the head reaches a second temperature higher than the first temperature at completion of the printing and generates damage in the head and erroneous operation. CONSTITUTION:When there is an output T1 from a temperature sensor 12, a printing of a page which is under printing presently ends. When there is not an image data of a next page, the printing ends as it is. When there is the image data of the next page and there is not an output T2 from the sensor 12, reading of the image data of the next page starts and printing operation for the next page follows. As time elapses until a thermal head starts the printing of the next page and the temperature of the head lowers, stopping of the printing is unnecessary. When there is the output T2 from the sensor 12, as there are erroneous operation and inside damage of the head, a CPU 8 does not read out the image data of the next page from an image memory 11 until the temperature lowers and the output T1 from the sensor 12 runs out, and stops printing operation of a recording section K.

Abstract: PURPOSE:To improve welding quality and yield by correcting a welding voltage from the result of inspection of a weld zone to obtain a fresh relation curve of a 'welding speed-welding set voltage ' and continuing welding in accordance with this relation curve. CONSTITUTION:The basic relation curve of the 'welding speed-welding set voltage' is formed by previously determining the relation of the required welding electric energy with welding speeds at every standard thickness of welding blank materials from experiment and is stored in a computer 10. The required welding voltage is determined in accordance with the welding sped detected by a speed detector 20 and the welding electric power is changed in accordance with this voltage. The actual welding operation is then carried out. The welding voltage is corrected from the result of the inspection of the weld zone to obtain the fresh relation curve of the 'welding speed-welding set voltage'. The welding is continued in accordance with this relation curve. The heat input is automatically changed according to a speed change in such a manner and the follow-up responsiveness is extremely improved.

Title: Electrical parts cooling device for air conditioner
Inventor: YOKOI TOSHIO
IPC: F24F5/00
Filed: 1986-08-07
Abstract: PURPOSE:To prevent rain drops from invading into the compressor chamber and prevent a temperature rise of electrical parts by providing the compressor chamber with an intake ventilating hole and multiple outlet ventilating holes in the top of a noise insulating plate which are open to the heat exchanger and are provided with an outlet ventilating hole cover. CONSTITUTION:When a fan 4 is rotated, the outside air passes through a heat exchanger 3 and is discharged out of the body 1 as shown by an arrow (a). The outside air also enters into the body 1, as shown by arrow (b), from an intake ventilating hole 6 in the lower part of the compressor chamber B, and passes there to a fan chamber through outlet ventilating holes 7 to join the main stream (a), and gets out of the body 1. When raining, rain drops hitting the fan 4 are prevented from entering into the compressor chamber B from the outlet ventilating holes 7 on account of an outlet ventilating hole cover 8. Rain drops hitting the heat exchanger 3 does not enter into the outlet ventilating holes 7 disposed in the top of a noise insulating plate 5 because they are obstructed by the heat exchanger 3. Therefore, a large quantity of air can be supplied to the compressor chamber B so as to prevent a temperature rise of electrical parts in the compressor chamber B without allowing rain drops into the compressor chamber B under rainy conditions.
