Title: Cross flow fan
Inventor: NAGAMORI AKIRA
IPC: F04D17/04
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To effectively reduce blasting noise without reducing the blasting quantity by forming each blade of a cross flow fan of a thin metal plate. SOLUTION: Each blade 14 is formed of a thin metal plate of about 0.8mm or less in plate thickness into such circular arc shape that cross-sectional shape is inclined forward in the rotating direction of a fan. Such blades 14 are horizontally fixed between a pair of end plates 12, 13 so that the rotating direction front edge of each blade 14 is linearly inclined by a specified angle from the rotation axis Oa of the fan in the rotating direction of the fan, thus forming each blade 14 into a skew blade. With the plate thickness of each skew blade 14 made thin, the separating quantity of air flowing along the protrusive circular arc face side of each blade 14 is reduced so as to reduce the generated quantity of vortex caused by the separation of flow.  The generated quantity of eccentric vortex generated being accumulated near a nose is reduced by the decrease of vortex so as to reduce low frequency noise specific to a random skew cross flow fan caused by this eccentric vortex.

IPC: H03M1/10
Filed: 1993-09-20
Abstract: PURPOSE:To enable analog signals synchronous with the optional digital timing signal of a control system to be easily and surely taken in by a method wherein the digitally converted result of an analog signal of a targeted analog circuit is read out from a memory only by optionally giving a timing control signal to a timing control circuit. CONSTITUTION:When a timing control circuit 4 receives an instruction such as a timing control signal 6b or the like from a host digital control system, it actuates a sample/hold circuit 1 after it decodes the instruction. An analog/ digital converting circuit 2 is actuated after it is controlled in timing if necessary, and a memory storing signal is given to a memory 3, whereby an obtained conversion result is stored in the memory 3. Instructed analog data are sampled and converted into digital data, and then the host digital control system reads out the conversion result from the memory 3 through the intermediary of a data read port 6a and executes processing.

Title: Device for controlling temperature of cordless iron
Inventor: KAMEI MASANORI
IPC: D06F75/26

Abstract: PURPOSE:To obtain a cordless iron whose set temperature can be automatically varied by providing a set temperature varying means which can vary the set temperature according to information about operating conditions, such as a lowered value of the temperature of a base surface during the operating time of the iron. CONSTITUTION:A control portion 8 mounted on a control substrate 9 in a handle portion and comprised of microcomputers controls the drive of a heater 3 via a power control portion 10 in response to input signals from a temperature sensor 6, both switches 5,7 and according to a control plan programmed in advance, and also controls the drives of a ready lamp 11 and a stand-by lamp 12 both of which indicate that an iron is ready to be used, and that of a buzzor 13 which indicates that the temperature of a base surface is lowered to that for feeding electricity. As a result, in the case of materials for which a user frequently uses the iron even with a slightly low operating temperature, such as small articles and thin cloth, waiting time can be shortened by means of lowering of set temperature, while in the case of materials for which the user uses the iron for a long time, such as large articles and thick cloth, the set temperature is heightened so as to extend the time during which the iron can be used; a cordless iron whose temperature is controlled to an optimal value according to the condition in which the user uses it is thus obtained.

Abstract: PURPOSE:To avoid deterioration of OFF characteristics and protect a gate electrode securely from breakdown caused by electric field by a method wherein an amorphous Si film extended outside the area of a gate electrode is made to have lower resistance to prevent photocurrent from flowing between a source electrode and a drain electrode. CONSTITUTION:An amorphous Si film 4 formed on a gate insulating film 3 is divided into an amorphous Si channel region 4a as an active layer and extended parts as amorphous Si island parts 4b by a source electrode 6 and a drain electrode 7. At the same time, even if peripheral light is applied to the amorphous Si island part 4b, photocurrent induced in the amorphous Si island part 4b does not flow into the channel region 4a. Therefore, even if the peripheral light is applied to the amorphous Si island parts 4b which have larger area then the gate electrode 2, photocurrent induced in the amorphous Si island parts 4b does not flow into the channel region 4a. Therefore, OFF characteristics is not deteriorated by the light application.
