Title: Back light
Inventor: OGAWA SOICHIRO
IPC: G09F9/00
Filed: 1988-11-14
Abstract: PURPOSE:To make the efficiency of a light conductor the optimum by specifying the thickness of the light conductor to a bulb diameter of an applicable lamp. CONSTITUTION:White paint 5 is applied tightly on acryle at three side surfaces and the bottom surface of acrylic light conductor 2 of a thickness (t), so light generated from a lamp 1 of a bulb diameter D gets into the acryle to be reflected at a white painted surface without leaking externally, and a diffusion plate 4 is installed on the top surface of acryle. The light is used for a flat light source from the acryle top surface through the diffusion plate 4. In this case, for securing the minimum required efficiency for a light conductor, it is set as t/D>=1.2. The optimum light conductor thickness can thus be obtained with the weight added, thereby a thin back light of a good efficiency can be realized.

Filed: 1989-11-02
Abstract: PURPOSE: To reduce sound by supplying compressed refrigerant to a muffler and diverting and discharging a portion of the compressed refrigerant into the upper level of the oil in an oil sump when the pressure in the muffler is high. CONSTITUTION: Compressed refrigerant from a compressor is delivered to a muffler chamber 13 of a muffler 10 through heads 17, 19. Most of the compressed refrigerant flows through an exhaust pipe 18 to a condensation chamber of a cooling device. A portion of the compressed refrigerant is delivered through an orifice 30. When the pressure in the muffler 10 at that time is a high pressure of at least 100 pound/inch<2> as compared with the pressure in the lower portion of the compressor, a portion of the supplied compressed refrigerant is diverted. The compressed refrigerant flows into the upper level of the oil in an oil sump 90 through an orifice. The compressed refrigerant flown into the oil sump 90 is driven out to the upper level of the oil without disturbing the lower level of the oil. Refrigerant in oil in the upper level of the oil sump 90 is super-saturated.  The refrigerant is not solved in the oil, thereby froth is created, which reduces the noise.

Filed: 1989-11-06
Abstract: PURPOSE:To correct the variance of an electrification potential and to form a satisfactory image by providing a developing bias value setting means, a toner attaching amount sensor and a control means. CONSTITUTION:First, a lamp 7 is lit to illuminate a sensor pattern 6. A reflected light is led to the exposure surface of a photosensitive body via an optical system 8, and a pattern latent image is formed and developed into black by a developing unit 2. This developed image is not transferred to a paper, but is rotated as it is, and is brought to a position facing a detecting sensor 3. It optically detects the reflection density of the pattern image, and a controller controls the rotation of a toner supply roller 2c based on the detected output and maintains the detected density at a fixed level. By interlocking with a change in the electrification potential, a developing bias value is modified to develop the image. The sensor detects a toner attaching amount, and the reference potential of the sensor is determined through mutual comparison, thereby obtaining a stable, satisfactory image.
