Title: Repeating system of time-division multiplex multiple access system
Inventor: ORIGASA HIROMI
IPC: H04J3/00
Filed: 1981-01-09
Abstract: PURPOSE:To improve frame efficiency by setting the length of a preceding signal to be added to a time slot to one repeating section, by newly generating the preceding signal for a clock and a start signal at a repeating station. CONSTITUTION:A detecting circuit 5, once detecting a start signal ST in a received signal, triggers a control circuit 7. The circuit 7 stores an information signal INF in a memory 6 and then starts a generating circuit 8 to generate a preceding signal P and a signal ST newly, which are transmitted. The signal INF in the memory 6 is then transmitted. At a next repeating station, the heat part of the signal P is absent until the clock synchronism of a synchronizing circuit 3 is obtained, but the circuit 8 generates the signals P and ST newly, so the tranmitted signal is the same as that of the preceding station.

Title: Tape driving device
Inventor: FUJITA MASAHIKO
IPC: G11B15/32
Filed: 1982-01-13
Abstract: PURPOSE:To prevent the generation of a play in a loaded reel in the driving shaft direction, by butting the end of a rotary shaft to a stator member with the continuous sucking force in the axial direction while the rotary shaft is turning. CONSTITUTION:A reel shaft driving mechanism contains a decelerating deice  provided with a special motor 51 and gears 59 and 41 and a reel shaft part 35.  The motor 51 contains a rotor part including a shaft 52 and a circular magnet  54 adhered to the shaft 52 and a stator part including a driving coil 55 set opposite to the magnet 54, a stator yoke 56 adhered with the coil 55 and a housing  part 58 adhered with a bearing 57. The rotor part can turn freely to the stator  part. At the same time, one side of the magnetic flux of the magnet 54 reaches  a contiguous magnetic pole through the coil 55, the yoke 56 and the coil 55  again to close the magnetic path of the magnetic pole. While the magnetic flux  of the other side passes through a rotor yoke 53 to close the magnetic path of  the yoke 53. The sucking force acts on the area between the rotor part and the yoke 56, and therefore the rotor part is always attracted toward the yoke 56. Thus no play is produced between the rotor part and the yoke 56.

Title: Method of forming double-layered resist pattern
Inventor: KAWAZU YOSHIYUKI
IPC: H01L21/3065
Filed: 1990-01-10
Abstract: PURPOSE:To improve accuracy of dimensions by forming a combined layer comprising silicon and oxygen on the superficial layer of a resist layer including silicon in the first stage of oxygen reactive ion etching, and by performing an anisotropy etching on the lower resist layer in the second or later stage with the high frequency electric power at a higher frequency than for the first stage. CONSTITUTION:Resist layers 2, 3 are formed on a wafer 1, and the lower resist layer 2 is formed with a novolac resist and the upper resist layer 3 is formed of the resist including silicon. The first stage of oxygen reactive ion etching is performed on the superficial layer of the resist layer 3 including silicon with a high frequency electric power for combining silicon with oxygen in a plasma state, to form a combined layer 4 comprising silicon and oxygen. Therefore, the layer 4 prevents an etching mask 5 made of silicon-containing resist from being etched when the second or later stage of oxygen reactive ion etching is performed with the high frequency electric power at a higher frequency than for the first stage and an anisotropy etching of the lower resist layer 2 is performed. Thereby, the resist pattern having the small difference between converted dimensions can be formed.

Title: Semiconductor memory
Inventor: SUZUKI TOMIO
IPC: G11C11/401
Filed: 1990-01-09
Abstract: PURPOSE:To shorten discharge time or to suppress a discharge current corresponding to a power supply voltage by providing a sense amplifier to be connected or disconnected to a bit line corresponding to the power supply voltage in addition to a sense amplifier connected to the bit line. CONSTITUTION:When the power supply voltage is higher than a prescribed level, a select transistor 5 is turned OFF and a sense amplifier B51 is not connected to the paired bit lines since the output of a power supply voltage level detecting circuit is L. Therefore, the paired bit lines are discharged only by a sense amplifier A. ON the other hand, when the power supply voltage is lower than the prescribed level, the select transistor 5 is turned ON and the sense amplifier B is connected to the paired bit line since the output of the power supply voltage level detecting circuit is H. Therefore, the paired bit lines are discharged by the sense amplifiers A and B. Thus, when the power supply voltage is low, the discharge time is shortened and when the voltage is high, the generation of noise is suppressed by suppressing the discharge current.

Title: Gas sensor
Inventor: MITSUYOSHI TADAHIKO
IPC: G01N33/00
Filed: 1981-01-12
Abstract: PURPOSE:To highly precisely detect concentration of inflammable gas in air  without being affected by ethanole, by a method wherein a gas filter, mounted around a gas responsing product, is formed by the use of CaCl2. CONSTITUTION:A gas filter, mounted around an inflammable gas responsing product 1, is formed by the use of CaCl2. Ethanole in air, or gas, is caused to make a chemical reaction to CaCl2 of the gas filter 2 as shown in a formula to prepare a molecular compound to selectively free of the ethanole. Gas to be detected, e.g., hydrogen, carbon monoxide, methane, butane and the like, does not react to CaCl2, and as a result, it is prevented from damaging a gas detecting sensitivity. CaCl2 gets rid of moisture in air as well, and this permits it to be prevented from changing of its detecting sensitivity to gas to be detected due to humidity in air to improve reliability of a gas sensor. Additionally, it has an ammonia gas absorption ability, which results in enabling to perform a high- precise detection of inflammable gas being not affected thereby.

Title: Nozzle angle adjuster for variable delivery supercharger
Inventor: MITSUBORI TAKESHI
IPC: F02B37/12
Filed: 1989-01-10
Abstract: PURPOSE:To make it possible to cool a nozzle shaft and dispose the nozzle shaft at a lower temperature section by supporting the nozzle shaft freely rotatably near a water jacket of bearing wheel chamber. CONSTITUTION:A nozzle shaft 35 is supported on a water jacket 27 side of a bearing wheel chamber 3. This causes water flowing through the water jacket 27 to cool and lower the temperature of the nozzle shaft 35. The heat of a nozzle 9 is prevented from being transmitted to a nozzle drive device 37 to prevent its temperature from rising. Because the nozzle drive device 37 itself is disposed at a bearing wheel chamber 3 section of a lower temperature in comparison with a turbine section 1, its temperature is also lower. Thus, damages on the nozzle shaft 35 and nozzle drive device mechanism 37 due to high temperature oxidation and wear are suppressed to improve durability and reliability.
