IPC: F25D11/02
Filed: 1992-01-10
Abstract: PURPOSE:To enable only a fast cooling or a rapid defreezing to be carried out at a storing chamber within a refrigerator chamber. CONSTITUTION:When a freezing chamber cooling fan 10 or both the freezing chamber cooling fan 10 and a cooling device 14 are operated, cold air is fed into a cold air feeding passage 3. When a cold air damper 5 and a cold air return damper 25 are opened and a through-flow fan 7 is rotated, cold air from the cold air feeding passage 3 is flowed from the cold air feeding passage 3 into a storing chamber 6 through.a cold air feeding port 4a and is returned to the cold air feeding passage 3 through a passage 24 and a cold air return passage 23. When the cold air damper 5 and the cold air return damper 25 are closed and the through-flow fan 7 and a defreezing heating heater 19 are operated, the hot air heated by a defreezing heating heater 19 passes through a ceiling duct 16, the through-pass fan 7 and the storing chamber 6 and then a rapid defreezing is carried out at the storing chamber 6. When the fast cooling is carried out at the storing chamber 6, the cold air is not leaked out of the storing chamber 6 into the storing chamber 2 and the freezing of the food within the refrigerator chamber 2 can be prevented.

Title: Fiber structure for reinforcing external wall mortar
Inventor: MURAYAMA SADAMITSU
IPC: E04F13/04
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To bring out a sufficient reinforcing effect in a reinforcing and repairing work of an external wall, by compositely forming a netted sheet in which long fiber threads are arranged in a plurality of directions on non- woven fabric constituted of a short fiber. SOLUTION: A netted sheet 2 in which long fiber threads are arranged in a plurality of directions in non-woven fabric 1a, 1b constituted of a short fiber, is compositely formed. It is preferable that high strength long fiber threads having 10g/de or more tensile strength are used for the external wall reinforcement of a large structure. If the long fiber threads are less than 10g/de, the quantity of fiber must be increased to secure both directional strengths. As a result, the impregnation or resin becomes insufficient and hence, a fear that mortar does not penetrate correctly is brought. When taking the seepage of mortar on execution into consideration, the fiber fineness of the non-woven fabric is preferably 5-90de. And it is also preferable that these are used as non-woven fabric sheet having 5-150g/m<2> in weight (Metsuke).

     CONSTITUTION: When microwaves are transmitted, the heat of a dielectric 12 is applied to a heat pipe part 13 which is in contact with the dielectric and is obtd. by hermetically sealing a heat medium in a cylinder of metal or the like, then the working fluid existing there evaporates and develops a pressure difference between the same and a heat radiation part. The vapor moves at high velocity to the heat radiating part. The moved vapor condenses on the inside wall of the heat radiation part, and the latent heat of evaporation is released through heat radiation fins 14. The working fluid condensed in the heat radiation part is returned to the heating pat in contact with the dielectric 12 by the capillarity of wick. As for the shape of the heat pipe 13, a pipe provided with spiral heat radiation fins around the same is available.

IPC: H04B1/04
Filed: 1992-01-14
Abstract: PURPOSE:To prevent increase in a transmission output level of a transmitter due to a fault of a receiver. CONSTITUTION:Upon the receipt of a signal SO from a receiver 2, a BER detector 4 detects reception signal line quality based on the signal and outputs line quality deterioration alarm information S3 when the detector 4 detects a deteriorated BER more than a predetermined BER. A discriminator 5 is provided with a timer whose time is able to be set and when the detector 4 outputs continuously the information S3 longer than the setting time of the timer, the discriminator 5 outputs device fault information S4 to a transmission power controller 3. When the discriminator 5 outputs the device fault information S4, the controller 3 discriminates it that no fading is caused but a device fault takes place even when the information S1 represents the decrease in the reception input level and the controller 3 outputs immediately a control signal S2 to decrease the transmission output level of the transmitter 1 to a minimum level.

IPC: F16K15/02
Filed: 1987-01-12
Abstract: PURPOSE:To obtain stable valve closing without leak, by forming a spring bearing into a star-fish shape that is obtained by adding legs to a cone-shaped head part and holding a valve-disc-pushing spring by means of these legs for stable spring holding. CONSTITUTION:A valve disc 2, which closes a valve seat 1c at the back of a housing chamber 1b of a through-flow-passage 1a of a main body 1, is pushed from behind by a coil spring 3. The coil spring 3 is held by legs 4a of a valve receiver 4, which acts as a spring and which is formed into a star-fish shape that is obtained by adding legs 4a to a cone-shaped head part 4b, while the legs 4a are inserted into corresponding grooves 1d. When the valve is full open, the head part 4b of the spring receiver 4 abuts on the valve disc 2 in order to hold it. With this contrivance, the valve disc 2 can be closed in a stable manner. Moreover, since there is no sliding part between the spring receiver 4 and the coil spring 3, the valve can withstand repetitive use, thereby ensuring a long life-span.

Title: Optical cell
Inventor: FUJII TOSHIKO
IPC: G01N21/27
Filed: 1995-01-17
Abstract: PURPOSE: To realize highly accurate and convenient analysis of a trace liquid component by a constitution wherein a cooling element disposed on a attenuated total reflection prism through a sample controls the cooling rate. CONSTITUTION: A sample 2 is introduced onto an attenuated total reflection prism (ATR) 1 and a current is fed to a Peltier element 5 from a DC power supply 7 through a temperature controller 8 to start cooling of the sample 2. The Pettier element 5 is regulated to a constant temperature by means of a temperature regulator 11. When the temperature of the sample 2 drops below a freezing point, the regulator 8 increases the current supply to the element 5 thus accelerating the cooling rate of the sample temporarily. Consequently, phase transition takes place in the sample 2 to start freezing. The frozen sample 2 is measured by means of the light 14. The light 14 is reflected 16 to enter into the end face of the ATR 1 through a window material 15.  The incident light propagates through the ATR 1 by total reflection and specific wavelength is absorbed by the sample 2 before leaving the other end of the ATR 1 and detected by a detector through the window material 15 and a reflector 16. With such arrangement, a trace liquid component can be analyzed conveniently with high accuracy.

Filed: 1990-01-11
Abstract: PURPOSE:To prevent the formation of deflection due to the heat of a wafer by using a wafer supporting plate for a wafer supporting tool used in a vertical oxidizing/diffusing LP-CVD apparatus and the like. CONSTITUTION:In a wafer supporting tool 16 of a vertical LP-CVD apparatus, a wafer-supporting plate 15 for supporting a wafer 14 is mounted on a flange 7. The plate is inserted into a reaction chamber 6 with an elevator 8. The intended temperature is kept with a heater 9, and reacting gas 11 is introduced into the reaction chamber 6 under this state. Thus treatment is performed. At this time, when high-temperature treatment is performed, the strength of the water 14 itself is decreased. Since the wafer is in contact with the entire surface of the wafer supporting plate 15, however, stress is not concentrated on a specified place, and the deflection of the wafer 14 due to the weight of the wafer 14 itself does not occur. Furthermore, a notch 17 and the like can be provided in the supporting plate 15 so as to facilitate the attaching and removal of the wafer 14 to and from the wafer supporting plate 15.
