Patent JP-H11237159-A (JP)
Title: Refrigerator
Inventor: SAITO TETSUYA
IPC: F25D19/00
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To improve response property upon switching between a cooler for refrigerating chamber and a cooler for freezing camber to reduce the occurrence of noise by a method wherein a space is provided in the reverse direction of a valve driving unit, whose volume is large, and a refrigerant control device is installed compactly. SOLUTION: In a refrigerant control device 5, a pipe 14 is formed so as to be directed downward whereby the pipe will not be superposed with a valve driving unit, whose volume is large, and a refrigerant control device 5 is permitted to be installed compactly. On the other hand, liquid refrigerant is stored immediately in the inlet port unit of a second capillary tube 7 upon closing the valve and the liquid refrigerant flows efficiently into a cooler for freezing chamber while gas refrigerant flows upward upon closing the valve and the liquid refrigerant is moved upward quickly by the flow speed of the gas refrigerant whereby response property upon switching between a cooler for refrigerant chamber and a cooler for freezing chamber is improved very much.  Further, the diameter of a first capillary tube 3 is enlarged step by into the flow direction of refrigerant and the discharging speed of the refrigerant is reduced gradually whereby the vibration of the first capillary tube 3 is reduced and the generation of noise is also reduced.

Title: Probe for photoelectric conversion type fingertip volume pulse wave detector
Inventor: HATTORI SHUJI
IPC: A61B5/0245
Filed: 1988-02-23
Abstract: PURPOSE:To detect the surface temp. of a fingertip simultaneously with the measurement of a change in a blood flow rate by mounting a photodetector for detecting light transmitted through the fingertip and a fingertip temp. detection element for detecting the surface temp. of the fingertip. CONSTITUTION:When a fingertip 10 is inserted in a dark box 1 and placed on a fingertip placing stand 6, the fingertip 10 closes a through-hole 7 to touch a fingertip temp. detection element 8. When the switch is closed, light is emitted from a light transmitting element 3 and transmitted through the fingertip 10 to be detected by a photodetector 5. A change in the resistance value of the photodetector 5 is outputted to a measuring device main body 11 as a change in voltage and converted to a pulse waveform. At the same time, the fingertip temp. detection element 8 detects the surface temp. of the fingertip 10 to output the same to the measuring device main body 11 and it is judged whether the temp. of the fingertip is proper, by the operation of the measuring device main body 11. Since the change in the blood flow rate of the fingertip 10 and the surface temp. thereof are simultaneously measured, the surface temp. of the fingertip 10 is displayed on the display part of the measuring device main body 11 and, further, when the temp. of the fingertip is extremely low, a warning is issued to make it possible to urge the temporary suspension of measurement.

Abstract: PROBLEM TO BE SOLVED: To obtain the excellent color reproducibility of video light by making the RGB components of emitted light have scattering characteristic that they reach a video observation range on a hologram screen while they are overlapped and mixed. SOLUTION: A video is reproduced on a hologram screen 1 by scattering and diffusing the video light 12 projected from a projection device 11 at respective points (a) to (c) or the like on the screen 1 so that the light 12 becomes the emitted light 13.

Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To reduce bridging sufficiently during a process for developing a resist in the fabrication of a semiconductor device. SOLUTION: A developer 4 is sprayed on a semiconductor wafer coated with a resist 2 to form a paddle 6 and a resist image 2 is developed on the surface of the wafer 1 by dissolving a part of the resist in the developer 4.
