Title: Ink jet printer and ink jet print head
Inventor: OGASAWARA FUMIHIKO
IPC: B41J2/175
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet printer and an ink jet print head wherein the frequency of occurrence of an image defect due to air bubbles is reduced significantly, the usage efficiency of ink to printing is improved, and the entire system is miniaturized. SOLUTION: An ink feeding member 11 is provided with an ink feeding section 21 leading from an ink channel pipe 13. The cross sectional area of the opening of the ink feeding section 21 is smaller than the area of the opening of a common liquid chamber 5, so the ink feeding section 21 communicates with only a part of the common liquid chamber 5. The flow velocity of ink in the ink feeding section 21 becomes faster. As ink flows toward the arrangement direction of nozzles 2 in the common liquid chamber 5, the cross sectional area in the flowing direction is small, making the flow velocity of ink fast. Therefore, air bubbles generated internally are accumulated near the end of the common liquid chamber 5 due to the flow of ink and are discharged easily by suction action. Thus remaining air bubbles can be reduced to a minimum.

IPC: H03J7/18
Filed: 1982-03-03
Abstract: PURPOSE:To obtain an identity discriminator which reduces the integration time and keeps discrimination surely, by providing a means for detecting the deterioration in sound signals, relating to a car radio receiver having two reception systems in the same broadcast frequency band. CONSTITUTION:While one reception system, e.g., a reception system 6 receives broadcast waves at first, when the other reception system 10 finds out a station with better reception state than the station in reception in the system 6, a controller starts the time waiting operation of a discriminating period after both of the two sound level discrimination signals are ''effective''. Simultaneously, the controller checks the two sound level discrimination signals intermittently or continuously, and when the two sound level discrimination signals are ''effective'' during the discriminating period T, a content discriminating signal is checked, and when the signal is ''coincident'' a sound switching device is switched to reproduce the sound signal of the reception system 10 and the station search is restarted with the reception system 6. When the content discriminating signal is ''dissident'', the search of the station without the signal is restarted with the reception system B10.

Title: Airconditioner for vehicle
Inventor: TAKAHASHI SEIICHI
IPC: F24F11/76
Filed: 1981-03-13
Abstract: PURPOSE:To perform temperature control of the inside of cars improving comfortability by reducing the time of air blow in accordance with the amount of solar radiation in an airconditioner that starts blowing out of air only when the temperature reaches a preset value. CONSTITUTION:When the amount of solar radiation is small, voltage VC is higher than the voltage VD at the point D because a resistance of a thermistor 91 of a solar radiation amount sensor circuit 9 is higher, which makes a comparator 93 unoperating. Therefore, in this condition, the blowing out does not start unless a water temperature switch 6 or an outside temperature switch 7 are turned ON. Meanwhile, when the amount of solar radiation is larger, the resistance of the thermistor 91 becomes low making VD higher than VC, generating an output from the comparator 93 which makes a transistor 94 operative, and a relay 95 is energized to flow a current in the relays 5, 3. The closing of the contacts of the relays applies a voltage on a blower motor 1 thereby enabling the controlling of the air blowing out.

IPC: B01J23/89
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To develop a highly active electrode catalyst for a fuel cell by recognizing the problem that a divergent increase in overvoltage has a serious effect on the lowering of the cell voltage of the fuel cell and noticing an electrode catalyst supposed to be related to the concn. overvoltage.

Abstract: PURPOSE: To remarkably improve the efficiency of the crater treating work by performing welding work by using only one of the 1st and 2nd welding power sources after the welding work has been performed by using both of these power sources simultaneously.  
     CONSTITUTION: When welding is started by two power sources, main and auxiliary power sources 1 1 , 1 2 , a relay 16 is energized and its contacts 16S are closed, then voltage is applied to a delay timer 20 and its contacts 20S are closed for a preset time. Then, a relay 21 is energized, and its contacts 21S are closed, so that the regular welding is accomplished by the large current transformed by the respective transformer 10 1 , 10 2  of the power sources 1 1 , 1 2 . When the preset time elaspses, the operation of the timer 20 goes off, and the contacts 20S are opened, by which the relay 21 is de-energized, and its contacts 21S are opened, so that the power supply from the power source 1 1  is broken. Hence, the crater treatment welding of the low current using exclusively the power source 1 2  is accomplished.
