Title: Drop type power source
Inventor: MIYANO KOICHI
IPC: H02M7/06
Filed: 1993-10-14
Abstract: PURPOSE:To improve the mountability and to suppress the power consumption by suppressing the rush current for power-on by a drop resistance and dividing the voltage applied to a smoothing capacitor by a limiting resistance. CONSTITUTION:The current flowing to a drop resistance 2 flows to a smoothing capacitor 4, and the electricity is stored in the smoothing capacitor 4. When the electricity is stored in the smoothing capacitor 4, the current starts to flow to a limiting resistance 5. Both ends of a Zener diode 3 are held at a certain voltage by the action of the Zener diode 3, and a load is connected in parallel to both ends to make a DC power source. The waveform in both ends of the smoothing capacitor 4 is determined by rating of the Zener diode 3, the resistance value of the drop resistance 2, and the resistance value of the limiting resistance 5. The voltage obtained by subtracting the voltage waveform in both ends of the smoothing capacitor 4 from the voltage waveform outputted from a diode bridge 1 is applied to the drop resistance 2, and the power consumption in the resistance for voltage drop is suppressed.

IPC: B41J2/005
Filed: 1986-10-30
Abstract: PURPOSE:To record clear images, by heating an ink applied to a porous film layer by a heat-applying means according to image information when the porous film layer is brought into contact with a recording medium. CONSTITUTION:An ink 18 is applied to a porous film layer 17 through a doctor blade 19 or the like in a predetermined thickness, and heat generating elements 22 of a heat generating part 21 are operated to generate heat in a pattern according to informations. The ink 18 lowered in viscosity by the heat generated by the elements 22 penetrates through the porous film layer 17 to the other side, thereby forming an ink image according to the information on the other side of the layer 17. At the time of formation of the ink image, the image is transferred directly to a recording medium 24 pressed against the porous film layer 17 by a platen roller 23, whereby a predetermined image can be recorded on the medium 24. Thus, clear images can be efficiently recorded in a stable state.

Abstract: PURPOSE:To preclude a wrong decision from being made owing to an error in the machining of a substrate by deciding that a red-hue picture element obtained by a hue conversion part is a picture element at a copper foil part when the value of the picture element is larger than a predetermined value. CONSTITUTION:A control part 46 reads an expanded land extraction area 49a out of a teaching table 38 and supplies it to an image processing part 39, and also supplies image data on an unmounted substrate 25 stored in a memory 37 to the image processing part 39, thereby cutting the image of the land extraction area 49a from said image data. Then the control part 46 supplies a hue lightness conversion command to the image processing part 39 to perform the hue lightness conversion of respective picture elements constituting the image in the land extraction area 49a. Further, the control part 46 calls a land extraction routine to extract a red hue Rc(ij) corresponding to one picture element (ij). Then, the control part 46 checks whether or not the red hue is larger than the predetermined land extraction reference value C and decides that the picture element (ij) is the picture element at the copper foil part when Rc(ij)>C.

Abstract: PURPOSE:To output an exclusive area aggregation at high speed with a few memories by taking out one rectangular area from a stack, horizontally or vertically dividing it into two and registering them to the stack in case of overlapping on other specific rectangular area and repeating until the stack is idled. CONSTITUTION:A control part 100 takes out one area R1 to be processed from the stack 500 to activate an overlapping decision part 300 between the areas and decide the overlapping on the area R2. At the time of no overlapping, this is completed and at the time of overlapping, an area dividing part 200 is activated to horizontally or vertically divide the processing area R1 into two areas overlapping the area where the area R1 is not overlapped with area R2 and area output part 400 outputs the area which is not overlapped of the divided areas to an exclusive area coordinate value table 700. On the overlapped area, a similar processing is repeated and completed when the stack 500 is idled. Thereby, the exclusive area aggregation is outputted as the sequence aggregation of the minimum number of rectangle areas at high speed by a few memories.

Title: Controller
Inventor: OWADA MITSURU
IPC: G05D3/12
Filed: 1989-10-02
Abstract: PURPOSE:To suppress the influence of quantization error by providing a sensor which outputs the analog information in response to the action of a control subject, a phase compensation circuit which receives input of the analog information, and a digital signal process circuit which digitizes the output of a phase compensation circuit and controls the control subject. CONSTITUTION:A signal is inputted to a phase compensation circuit 2 from a sensor 1 which outputs the analog information in response to the action of a control subject. The signal received by the circuit 2 is digitized by an A/D converter 3 and this digitization output is processed by a digital signal process circuit 14 which contains no phase compensation means. Then a necessary control signal is outputted for control of a drive circuit 5. In such a constitution, quantization error produced at A/D conversion is not amplified by the phase compensation of a control loop. Thus it is possible to ensure the stable control with no influence of the quantization error.

Filed: 1992-09-28
Abstract: PURPOSE:To provide a wood club head with which a ball trajectory of excellent directionability can be obtained, achieving an increased carry, even when hitting a ball at a position outside a sweet spot in a face. CONSTITUTION:A wood club head comprises a center zone 42 in which a face 41 of a head 40 surrounds a sweet spot, and an outer zone 43 surrounding the center zone 4, and a shot blast process is applied to the face 41 for setting a friction coefficient of the outer zone larger than a friction coefficient of the center zone 42. If a ball is hit outside a sweet spot, therefore, the ball is not curved much, or its carry is not decreased. The club can thus be positioned correctly in addressing compared with a club with which the friction coefficient is changed by changing intervals of grooves in the face.
