Abstract: PURPOSE:To prevent a leak in ozone generation while improving a sterilizing effect by disposing an ozone generating section on a position downstream of a heater in a drying air course while supplying current simultaneously or alternately to the heater and ozone generating section in the ozone generation. CONSTITUTION:A titanium catalyzer filter 27 for resolving ozone is disposed at the upstream side of a drain port 26, a heater 28 formed of positive characteristic thermistor is disposed at the downstream side of the drain port 26 and an ozone generating section 29 formed of a ceramic electrode is disposed at the downstream side of the heater 28. In a sterilizing process, an indicating unit 39 turns on and off a LED corresponding to the sterilizing process and a sterilization control section 47 operates the heater 28 and the ozone generating section 29, or alternately operates them in consideration of overheat of clothes and capacity of power source. This operation is continued until a sterilizing time counter 48 is counted up. The sterilizing operation applies high voltage to the ozone generating section 29 to generate ozone and supplies thereto dried air heated by the heater 28 to lower the relative humidity so that the ozone and dried air are supplied to a drum 10 to sterilize received clothes.

Title: Microstrip antenna
Inventor: SUZUKI YASUO
IPC: H01Q19/22
Filed: 1989-08-02
Abstract: PURPOSE:To produce the double resonance while suppressing the increase of manufacturing process, the cost, the thickness, the weight, etc., and to increase the frequency band by forming a conductor ring as a subconductor plate around a basic radiation element conductor plate. CONSTITUTION:A conductor ring 15 serving as a subconductor plate within the same surface as a radiation element conductor plate 11 and along the outer circumference of the plate 11. The inside basic plate 11 itself resonates with a high frequency of a desired band and then resonates with a low frequency as the whole body including the ring 15. Therefore the equivalent return loss characteristic shows the double resonance characteristic, and the frequency band is increased. Furthermore the ring 15 can be simultaneously produced with the plate 11 since it is just required to form the ring 15 around the plate 11. As a result, the double resonance is produced in order to attain a wide frequency band while suppressing the increase of the manufacturing process, the cost, the thickness, the weight, etc., of a microstrip antenna.

Title: Semiconductor device
Inventor: TAKAHASHI HIROYUKI
IPC: G11C11/419
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To unnecessitate NOR logic at a next stage of a differential amplifier circuit and to reduce load capacity in a sense amplifier circuit output terminal. SOLUTION: nMOS transistors M1 and M2 are operated as a differential amplifier by making a sense amplifier control signal SE1 a high level and supplying a current from a nMOS transistor 3. These output S, SB is approached to an intermediate potential being an operation point by the impedance of a pMOS transistors M4, M5 being a load, but a pMOS transistor M6 is turned on during a low state of a sense amplifier control signal SE2, and the device is made an equalizing state. As the pMOS transistor M6 is an equalizing state, logic supply of high output in the S, SB can be performed even in a non- activation state, therefore, NOR logic is not required. As NOR logic is eliminated as a circuit driven by the SE2 signal, a load is largely lightened, a sense amplifier control signal SE2 driving circuit can be miniaturized, and an operation current also can be reduced.

Title: Pattern synchronization circuit
Inventor: SEKI YOSHINORI
IPC: H04L7/08
Filed: 1990-07-30
Abstract: PURPOSE:To establish the synchronization even when one-bit error exists in a received pattern by regarding it as the establishment of the synchronization when a collation means collates that the received pattern is a synchronization end pattern and a count value of a counter is a prescribed value or over. CONSTITUTION:A carrier detection means 311 detects whether or not a reception data exists by a carrier sense signal CS fed from a radio reception circuit 22. A reception means 312 uses a clock CLK synchronously with a reception data DATA fed from the radio reception circuit 22 after the presence of the reception data is discriminated by the carrier detection means to sample the reception data DATA by one bit each. A collation means 314 compares the reception pattern fed from a buffer of a storage means 313 with plural synchronization patterns stored in a collation table 32. Thus, even when several bits of a synchronizing pattern signal cannot be received or one bit error exists in the reception pattern, synchronization is established in an excellent way.
