Title: Ink jet recorder
Inventor: OKUBO MASAHARU
IPC: B41J2/21
Filed: 1987-04-03
Abstract: PURPOSE:To obtain a color multivalued high-quality image, by converting a digital image signal into an analog image signal with a predetermined period, and generating a signal modulated in pulse duration by using a pattern signal generated by a pattern-generating circuit in synchronism with the generation of the analog image signal. CONSTITUTION:A digital data output device 101 converts image data into digital data, and outputs the digital data on a color component basis. One of color component signals is selected by a selector 102, and is inputted to a digital-to- analog converter (D/A converter) 103, in which the signal is converted into an analog quantity. The image signal 103S thus obtained through digital-to- analog conversion is compared with the signal level of a pattern signal 105S by a comparing circuit 104, which outputs a multivalued image data signal 104S modulated in pulse duration. According to the signal 104S, a high-frequency pulse signal 114S generated by an oscillator 114 is turned ON and OFF by a switching circuit 115 to obtain a multivalued head-driving signal 116S, which is supplied to a recording head, whereby a high-quality image can be obtained.

Title: Wire type change mechanism
Inventor: URABAYASHI NORIHIDE
IPC: F16H61/36
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a wire type change mechanism whereby a uniform shift feeling can be ensured and deterioration of fuel consumption can be suppressed, even when the turn direction of a shift lever is in any direction. SOLUTION: To a working shaft 4 moving a clutch hub sleeve displaced, a shift lever 9 is connected, in this shift lever 9, a weight 12 and a connection pin 10 are provided. To the connection pin 10, an operating wire 11 extended from a speed change operation lever is connected, the weight 12, when its center of gravity G1 takes a neutral position where the clutch hub sleeve is separated relating to meshing gears adjacent to each other, is set under the working shaft 4, so as to be positioned on a perpendicular line L1 passing orthogonally to an axis of this working shaft 4.  In this way, at shift operation time, with the perpendicular line L1 serving as the reference, with movement of the weight 12 in symmetry, action of the weight 12 is equalized, and also at neutral time, uneven contact of the clutch hub sleeve and the meshing gear is eliminated, so as to prevent generation of friction.

IPC: H01S5/343
Filed: 1991-03-21
Abstract: PURPOSE:To provide a quantum fine line structure and a manufacturing method therefor in which the structure is easily and stably formed by crystalline growing on a processed substrate to be included in a quantum interference device, etc. CONSTITUTION:Quantum fine line structures 19, 20 are formed on a laminate laminated on parts 13, 14 formed in a groove state, oblique surfaces of a protrusion of a substrate 24 by crystalline growing by including a quantum well layer 17. A thickness of a bottom of the groove of the layer 17 extended along the oblique surface of the groove is larger than that of the oblique surface.

Title: Image forming device
Inventor: SAITOU HIRONOBU
IPC: B65H29/54
Filed: 1989-04-03
Abstract: PURPOSE:To prevent a fixing roller from being damaged by a transfer material separation claw by fitting a buffer member to a pressing and separating mechanism for the transfer material separation claw and absorbing the shock power when the separation claw is pressed against a cylindrical member by the buffer member. CONSTITUTION:The separation claw 13 which separates and peels the transfer paper P off from the fixing roller 11 is pressed against the fixing roller 11 only when the transfer paper P is carried in a fixing device 5 and separated from the fixing roller 11 in other cases. Then, when the separation claw 13 is pressed against the fixing roller 11, the constant shock power is generated at the separation claw 13 by a spring member 19, but an oil damper gear 20 is supported pivotally on the main body side plate 10 of the fixing device 5 and a buffer gear 21 fixed on a rotary shaft 15 is engaged so as to prevent the constant shock power from being generated. Consequently, rotary torque is suppressed and the buffer gear 21, i.e. rotary shaft 15 rotates slowly, so that the separation claw 13 is pressed softly. Consequently, the separation claw 13 never damages the fixing roller 11.

IPC: G11B7/26
Filed: 1987-04-02
Abstract: PURPOSE:To obtain an information recording medium which maintains satisfactory joining over a long period of time by disposing a resin film so as to face an impressing horn and impressing ultrasonic waves on the film while pressurizing the same, thereby fusing and joining the film to a substrate. CONSTITUTION:An ultrasonic welding machine 10 consists of a receiving jig 16 and the impressing horn 17 disposed with annular build-ups 19a, 19b further on the respective surfaces of annular projecting parts 18a, 18b for impression of ultrasonic waves. The ultrasonic waves are oscillated from an ultrasonic oscillator 20 and are transmitted through a converter 21 to the impressing horn. This impressing horn is lowered to pressurize the resin film 11 by said horn and the build-ups 19a, 19b on the surfaces of the annular projecting parts 18a, 18b of said horn. While this state is maintained, the ultrasonic waves are impressed on the film 11, by which the film is fused and joined to the substrate 15. Since the joining of the respective members is executed by using the ultrasonic waves to quickly fuse and join the members in such a manner, the deterioration in the recording characteristics by the heat generated at the time of fusion and joining is drastically decreased.

Title: Polarity separating circuit
Inventor: HIRAGA MASATOMI
IPC: H03K19/14
Filed: 1983-05-12
Abstract: PURPOSE:To attain a polarity separating circuit driven with the same power supply as the driving power supply of a logical circuit by connecting respectively an output of a phototransistor (TR) in the 1st and 2nd photocouplers to a binary logic circuit. CONSTITUTION:In setting a setting voltage Vref3 of a constant voltage circuit 8 to an input signal level of a buffer circuit 1 in the relation as shown in the figure. When the input signal is a positive pulse, the photocoupler photodiode 6 is lighted and the photo-TR is turned on, and when the input signal is a negative pulse, only the photocoupler 7 is actuated. Since the on/off level of the photo-TR of the photocouplers 6, 7 is coincident with a binary level of a logical circuit 5, the TRs can be connected directly to the logical circuit 5, and the result of logical processing of a positive pulse train and the result of logical processing of a negative pulse train are outputted from its output terminal. Thus, no level converting circuit is needed and two kinds of power supply voltages are not required.
