Title: Output circuit
Inventor: FURUYA YASUSHIGE
IPC: H03K17/16
Filed: 1986-12-12
Abstract: PURPOSE:To eliminate the fluctuation of power voltage even at a large output current and high speed operation by connecting delay elements corresponding to number of output split transistors (TR) to each of prestage drive circuit in series and using a signal from a connecting point of each delay element as the input of the output split TR. CONSTITUTION:The plural output split TRs 3-8 connected in parallel in the P and N channels of output TRs and pre-stage drive circuits 1, 2 driving the P-channel and N-channel of the output TRs separately are employed. Then delay elements 40-45 corresponding to the number of output split TRs 3-8 are connected in series with each of the pre-stage drive circuits 1, 2 and a signal from the connecting points of the delay elements 40-45 become inputs of the output split TRs 3-8. Thus, even with a large output power capacity and high speed switching, the current consumption is suppressed and the power voltage fluctuation is suppressed.

Filed: 1990-10-31
Abstract: PURPOSE:To lower the source-drain resistance by a method wherein the first n-type semiconductor layer, the second high purity semiconductor layer in the less electron affinity than that of the former layer are formed and then the fourth n-type semiconductor layer is formed on the third n-type semiconductor layer between a Schottky electrode and an ohmic electrode.

Title: Laser light scanner
Inventor: FUNAKI SHINSUKE
IPC: B41J2/44
Filed: 1986-12-12
Abstract: PURPOSE:To move an image formation position forward and backward optionally by providing a storage means for storing frequency division information on laser light and a frequency divider which varies in frequency division ratio according to the output of the storage means, and modulating image information according to the output of the frequency divider. CONSTITUTION:When a photodetection signal is inputted from an optical detector, the outputs of an N frequency divider 41b and a counter 42 are cleared and when the optical detection signal falls, the N frequency divider 41 begins to divides the frequency of a 60MHz clock (a). When the output of N frequency divider 41 rises assuming that the output initial value of a PROM 43 is 0, the counter 41 counts the rise at the time of the rising and is started up. When the output of this counter 42 rises, the input address of the PROM 43 varies and the PROM 43 supplies '1' to the N frequency divider 41. When the N frequency divider 41 reaches a counted value 15, a carry signal C is outputted and inputted to its own -LD, and a load input '1' is loaded. Consequently, a laser light scanner which can moves the image formation position forward and backward optionally is realized without using any expensive delay line.

Inventor: FURUHASHI TOSHIO
IPC: F23D14/02
Filed: 1987-11-24
Abstract: PURPOSE:To make it possible to change flames from one side of a flame port plate to the other side of said flame port, minimize the number of parts and reduce production cost by forming a fitting groove to said flame port plate in a state parallel to the direction of a secondary air pipe, fitting said secondary air pipe into said fitting groove, forming an air ejection slit on the both side surfaces of the secondary air pipe in the upper part, and installing a crossbar in such a manner that it may cross the slit. CONSTITUTION:A required number of fitting grooves 131 are formed on a flame port 13 in a state substantially parallel to the direction of a secondary air pipe 16. The secondary air pipe 16 is fitted into the fitting grooves 131 in such a manner that an air ejection slit 161 may be exposed. The air eject slit 161 is formed over the upper side surfaces of the secondary air pipe in zigzag shape, centering on the upper ends of the secondary air pipe 16. A crossbar 162 is formed on the upper edges of the secondary air pipe in one piece configuration. Since this crossbar 162 is laid out in such a manner that it may cross the slit 161, flames can be changed from one side of the flame port plate 13 on the secondary air pipe 15 to the other side of the flame port plate 13 by way of the crossbar 162 in the slit 161 although the secondary air pipe 16 separates the flame port plate 13.

Title: Air conditioning device for vehicle
Inventor: TANIGAWA HISAMOTO
IPC: B60H1/00
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To negate the amount of thermal load increased by solar radiation when the quantity of solar radiation entering a car comportment is increased, and improve the defogging property of vehicle window panes in foot mode where the air conditioning wind blows out from both foot blowoff port and defroster blowoff port. SOLUTION: An air passage 7 for side face is adapted to be constantly open and ventilated by air conditioning wind. Then, when the quantity of solar radiation becomes higher than a specified value in foot mode, a cold air bypass passage 21 is opening by a cold air bypass door 22. Thus, the temperature of the air conditioning wind sent to the side face-air passage 7 is lowered to negate the amount of thermal load increased by solar radiation. Then, in this case, since a defroster-air passage 6 is ventilated by the air conditioning wind, the anti-dim property of vehicle window glasses can be ensured.

Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of an organic polymer catalyst and simplify BOD treatment in the next process in the treatment of an aqueous solution, especially wafer process wastewater, by using the catalyst. SOLUTION: A means, especially a treatment tank equipped with an ultrafilter membrane, for preventing the discharge of an organic polymer catalyst is used. While a treated aqueous solution being discharged, the catalyst deposited in the tank contributes subsequently to a reaction so that the addition of a conventional amount of the catalyst is enough to obtain due effects, and BOD treatment is simplified. Especially, when a BOD value is below a regulation value in an untreated stage, further BOD treatment can be eliminated.

Title: Manufacture of recording head
Inventor: SHIBATA MAKOTO
IPC: B41J2/16
Filed: 1985-12-27
Abstract: PURPOSE:To minimize energy dispersion of a discharge energy generator by forming each recording head arranged in the form of concentric circle in a film forming device. CONSTITUTION:Film thickness is almost equally distributed in the form of concentric circle, so that recording head units are prepared and arranged in the form of concentric circle. In case the curvature of a contour line of film thickness is small or a recording head is long, it is impossible to merely distribute the recording heads along the contour line. In such a case, the alignment direction of energy generators of the recording heads should be set along the contour line (along the tangent of the contour line 502), and at the same time, the recording heads should be formed and aligned so that of the energy generators to be arranged of each recording head unit, those located at the center or in the neighborhood of the center may come across the contour line 502 which establishes a tangent or its neighborhood. By forming the recording heads arranged in the above-mentioned pattern, it is possible to minimize the difference in characteristics of the energy generator in the recording head units, thus obtaining a high precision recording head almost free from energy dispersion.

IPC: H03M1/36
Filed: 1990-11-02
Abstract: PURPOSE:To cut off low level noise to make an output stable by providing hysteresis to a comparator. CONSTITUTION:The hysteresis is provided to each of comparators by providing an input buffer (5A-5(X-1)), a input resistor (6A-6(X-1)) and a feedback resistor (7A-7(X-1)) to each comparators (2A-2(X-1)).
