Title: Dehumidifying device for gas
Inventor: HARANO YOSHISHIGE
IPC: B01D53/26
Filed: 1981-04-08
Abstract: PURPOSE: To provide a dehumidifying device for gases which provides a high output of the dehumidified gas, is small in equipment size and consumes less electric power by making effective combination use of a vortex tube provided by just one piece to one system mechanism and a water cooler.  
     CONSTITUTION: The air which is compressed 1 is fed through an air filter 2, and a reducing valve 3 into an air cooler 4, where it is cooled with a blower fan 6 and is further fed into the curved pipe 10 in a water tank 8 where it is cooled and is released 12 of moisture. If necessary, the cold air after the releasing of moisture is discharged through a silencer 16 out through a dehumidified gas outlet 21. Part of the cold air out through the pipe 10 in the water tank 8 is branched just before an instrument 15 such as flowmeter, and is forced into a vortex tube 17 through a flow rate control valve 14. The warm air discharged from the tube 17 is discharged 21 to the outside of the mechanism device, and the other cold air is foamed by a foamer 19. While the foam cools the water in the tank 8 and the pipe 10, it is captured by a cover 7 and this air is fed to the fand 6 surface and is used for cooling the device 4.

Title: Humidity sensor using optical fiber
Inventor: MIYAI YOSHIO
IPC: G01N27/00
Filed: 1988-03-08
Abstract: PURPOSE:To obtain a humidity sensor whose structure is simple and characteristic is stable even when the sensor is used for a long time by applying the sensitive property of an optical fiber itself to the sensor. CONSTITUTION:A branched optical path 4 of the laser light from a laser 1 is formed by a half mirror 2 provided on a main optical path 3. The 1st optical fiber 7 has a property which expands and contracts in corresponding with a change in humidity and its part is arranged in a state where the part reacts to the humidity as a humidity-sensitive section 7a. The 2nd optical fiber 8 is made of the same material as that used for the 1st optical fiber 7 and arranged in a state where the optical fiber does not react to the humidity. When a gas to be measured changes in humidity, the length of the optical path is changed due to the expansion or contraction of the 1st optical fiber 7 and the output light of the fiber 7 produces a phase difference against the output light of the 2nd optical fiber 8. A photoreceptor section 9 detects the phase difference and an arithmetic section 10 calculates the then humidity in accordance with the output signal of the section 9 and outputs a signal corresponding to the calculated humidity.

Inventor: INOUE AKIO
IPC: H05B3/70
Filed: 1988-03-07
Abstract: PURPOSE:To prevent the burnout of the heating wire due to the short circuit of adjacent coil portions by pushing in and holding the coiled electric heating wire in a flexible ceramic fiber body under a pressure with a pressing member. CONSTITUTION:A ceramic fiber blanket 16, a cushiony ceramic fiber body 18, a coiled electric heating wire 20 and a pressing member 22 made of silica glass are heaped up in this order. This assembly is sealed in a frame including a base plate 12 and periphery walls 14, and the said heating wire 20 is pushed in the body 18 through a pressing member 22 so as that the coil of the wire 20 is wholly enclosed in the body 18, and holded there. In an electric heater with such a structure, the movement of the heating wire 20 is impossible. Because of the large heat insulation of the ceramic fiber, the heat emitted from the wire 20 is almost emitted to the outside through the pressing member 22 of large thermal conductivity and only small portion of which is conducted to the side of the body 18 and the blanket 16.

Title: Semiconductor memory
Inventor: KUMAGAI TAKASHI
IPC: G11C11/409
Filed: 1988-03-09
Abstract: PURPOSE:To avoid the malfunctions or the delay of access time caused by the deviation of equalization levels by providing a circuit which short-circuits the input/output terminals of a logic circuit which is activated by an internal control signal. CONSTITUTION:A short-circuiting circuit 4 short-circuits between the input/ output terminals of a logic circuit 3 which is activated by an internal control signal. The circuit 3 is activated by an internal control signal at the time of equalization and the circuit 4 conducts. Thus the input/output terminals of the circuit 3 are fixed at its logic levels. Then the circuit 3 transfers output data on a sense amplifying circuit 2 as soon as this circuit 2 is activated at the end of equalization. As a result, the delay of the access time equivalent to the timing difference between the sense amplification activating signal and the control signal of a transfer circuit can be eliminated.

Abstract: PURPOSE:To stop supplying electric power in response to a temperature change due to the blowout of a bubble in a device which for heating, pressing and stretching a resin tube between two pairs of nip rolls, by dividing heating elements from one another in a circumferential direction and regulating voltages depending on thickness. CONSTITUTION:A tube 14 is moved to receiving nip rolls 2 through feeding nip rolls 1 and a heating furnace 3.

Title: Manufacture of semiconductor device
Inventor: HIRATA KATSUHIRO
IPC: H01L21/31
Filed: 1987-03-10
Abstract: PURPOSE:To prevent a region of an impurity diffusion layer from enlarging unnecessarily while a shape of a step difference part of a layer insulating film is sufficiently relaxed, by adding a process where at least a part of a component which functions as the step difference part on a semiconductor substrate is covered with a high melting point metal or a high melting point metallic compound and further performing heat treatment by radiation of infrared rays. CONSTITUTION:After an oxidizing film 2 is made to grow on a semiconductor substrate 1 by a thermal oxidation method or the like, a polysilicon layer 3 is piled on the film 2 and further an R metal layer 4 is piled on the layer 3. In succession, the R metal layer 4 and the polysilicon layer 3 are patterned to be formed into a gate electrode of prescribed width, and next the gate electrode is used as a mask so as to form impurity diffusion layers 5 on its both sides. After an underlaid oxidizing film 6 is formed on this diffusion layer 5, a layer insulating film 7a is formed over the whole including the gate electrode part. When heat treatment is performed by an infrared ray lamp annealing method in order to relax a shape of a step difference of the gate electrode part, the layer insulating film 7a having the step difference shape near the R metal layer 4 is locally heated. Thus, the shape of the step difference is relaxed by softening, however, the impurity diffusion layer 5 is prevented from enlarging unnecessarily.
