Title: Axial fan
Inventor: KAWAGUCHI SEIJI
IPC: F04D29/38
Filed: 1989-03-06
Abstract: PURPOSE:To reduce the rotational noise of an axial fan attributable to a variation in an attach angle by installing a thin blade camber in a specified range of the maximum camber, while setting up a maximum camber position in the specified range of chord length. CONSTITUTION:An axial fan is provided with a boss part 6 rotating upon receiving driving force and five blades 7 connected to an outer boundary of this boss part 6. A maximum camber (a) and a maximum camber position (b) of each blade 7 exert a large influence on pressure coefficient distribution on a blade suction surface 7a when an attack angle is varied. The maximum camber is installed within the range of 5-8% in chord length. The maximum camber position (b) is set up in the range of 20-40% in the chord length. Thus, since pressure fluctuations can be held down to smallness, the extent of rotation noise in the axial fan attributable to a variation in the attack angle can be thus reduced.

Title: Device and method for fetching image
Inventor: MABUCHI ATSUSHI
IPC: H04N5/907
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To minimize the capacity of a buffer memory provided inside a video fetching device by fetching image data while suitably switching its method for the unit of a field or a frame based on an instruction from a host processor. SOLUTION: When the instruction for fetching the image data for the unit of a frame is received from a host processor 7, an internal control part 4 of an image fetching device 10 asserts a frame data fetching instruction signal 5 to an image input interface control part 3. When the frame data fetching instruction signal 5 is asserted, the image input interface control part 3 switches the fetching method of image data from control, which is executed up to the moment, for alternately storing only one field of each frame of image data into field buffers 1 and 2 to control for separately storing both the fields of one frame into the field buffers 1 and 2. Thus, one frame of data or the like of still pictures can be surely fetched into the host processor 7.

Title: Remote level adjustment control system for terminal equipment
Inventor: NAITO TSUNEO
IPC: H04M3/42
Filed: 1992-03-13
Abstract: PURPOSE:To eliminate the need for level adjustment implemented individually by a terminal equipment and to enhance the efficiency of maintenance by using a pushbutton signal as a control signal between the terminal equipment and an exchange. CONSTITUTION:When a stepwise level adjustment signal comprising combination of pushbutton signals from an exchange 1 is sent to a terminal equipment 2, the terminal equipment 2 receives the signal by a pushbutton signal receiver 3 and informs it to a microprocessor 6. When the processor 6 receives a 4-digit pushbutton signal normally, the processor 6 checks the content of request and returns a normal reply via a pushbutton signal transmitter 4 when no error is in existence and returns an error reply when in error. Furthermore, the processor 6 implements the control to an automatic level adjustment device 5 so as to be set to a commanded level. Thus, the exchange 1 applies remote level adjustment to the automatic level adjustment device 5 provided in the terminal equipment 2 whose stepwise level adjustment is attained.

Title: Liquid jet recording head, manufacture thereof and liquid jet recording device with the head
Inventor: IMAMURA ISAO
IPC: B41J2/16
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid jet recording head which has in an ink flow path a surface modified layer showing outstanding properties such as solvent resistance, chemical resistance, wettability the ink and adhesion to a foundation by providing a layer which becomes hydrophilic consisting of a baked layer of perhydropolysilazane expressed by a specified structural formula, on the liquid flow path surface of an ink flow passage. SOLUTION: A layer which becomes hydrophilic consisting of a baked layer of perhydropolysilazane expressed by formula is provided on the liquid flow path surface of an ink flow passage. A nitrogen atom and a hydrogen atom contained in the molecule of perhydropolysilazane are removed and an oxygen atom is introduced into the molecule by thermally baking the perhydropolysilazane in an air atmosphere. Consequently, the perhydropolysilazane forms a fine film almost free from cure contraction by baking process. In addition, the baked layer of the perhydropolysilazane which is thermally formed shows outstanding properties such as solvent resistance, chemical resistance, wettability to the ink and adhesion to the surface of a liquid flow path wall material as a foundation.  Thus the baked layer becomes a best suited surface modified layer as a new layer which becomes an ink source in the liquid flow path.

Title: Production of press-compacted and sintered body
Inventor: IWASAKI YOSHIMITSU
IPC: B22F3/02
Filed: 1991-03-19
Abstract: PURPOSE:To determine optimum pressing conditions and to enable stable mass production by measuring the weight of a press-compacted body as a sample immediately after compacting and the weight after drying and calculating the bulk density of the compacted body. CONSTITUTION:A slurry is press-compacted with a metal mold, the weight WG of the resulting molded body is immediately measured and the volume VG of the compacted body is calculated from the measured dimensions of the mold. The compacted body is then rapidly dried with a drier, the weight WD of the dried compacted body is measured and the apparent density rhoa of powder forming the compacted body is calculated by an equation rhoa=WD/[VG-(WG- WD)/rho0]. The bulk density rhob of the compacted body is also calculated by equation I. In the equations, rhoG=WG/VG and rho0 is the specific gravity of a liq. forming the slurry. Since the bulk density rhob of the compacted body can rapidly be calculated and exact evaluation of the porosity is enabled even in case of high press compacting pressure, optimum press compacting pressure can always be determined.

Title: Adding and subtracting circuit
IPC: H04N5/14
Filed: 1992-03-13
Abstract: PURPOSE:To decrease the number of the bits of input/output signals and to decrease the scale of the circuit scale by coupling the least significant digit bit of (m)-bit data with the output data of an adder or subtracter. CONSTITUTION:The least significant digit bit(LSB) is separated from the 10-bit input signal and the data of the remaining 9 bits are inputted to the adder 4. Then, data of 8 bits are passed through a delay element 2 and then inputted to the adder 4 as they are without being doubled. The adder 4 adds both the data together and outputs the addition result as 10-bit data. The least significant digit bit of the 10-bit input signal is coupled with the least significant digit of the 10-bit data of the addition result to obtain the 11-bit data. Therefore, the least significant digit bit of the 11-bit output data of the addition result is equal to the least significant digit bit of the 10-bit input data without fail. Namely, the adder 4 can generates the 10-bit output instead of the 11-bit output.

Title: State detector for liquid or the like
Inventor: KATOU TAKAYUKI
IPC: G01F23/24
Filed: 1984-03-22
Abstract: PURPOSE:To detect the state of a liquid such as a liquid level easily with high precision by utilizing >=2 thermistors having the same positive temperature characteristics and utilizing the potential difference which is generated between the positive characteristic thermistors according to temperature. CONSTITUTION:Positive characteristic thermistors P1 and P2 forming a detection part 3 are powered on by a power source part 1 through resistances R1 and R2 of a display part 2 to heat up. When the thermistors P1 and P2 are both dipped in a liquid O, there is no temperature difference between the both and their resistance values are nearly equal. Therefore, potentials at both terminals of a light emission diode D1 are nearly equal and there is no potential difference, so no current flows through the diode D1, which is off. If the liquid in a container 4 decreases until the thermistor P2 is exposed to air in said balanced state, the radiation state of the thermistor P2 is improved and the thermistor heats up to generate some temperature difference between both. Therefore, the diode D1 turns on owing to the current difference between the thermistors P1 and P2 and the level of the liquid is detected. Thus, the device which detects the state of the liquid easily with high precision is obtained.
