Abstract: PURPOSE:To maintain etching quality in an etching process by constructing a metal wiring region, with a simple pattern, designed using a CAD in a space region with a spacing not less than the given one. CONSTITUTION:An X-direction wiring pattern 6 and a Y-direction wiring pattern and connecting regions 8, shown by parts having oblique lines, are drawn and arranged in an interblock wiring region 5 between blocks 3. Then, an X-direction wiring pattern excluded region 9, being the interblock wiring region 5 from which the X-direction wiring pattern 6 is excluded and which includes the Y- direction wiring pattern, is recognized by a CAD. Next, the X-direction wiring pattern excluded region 9 is contracted, with it being kept apart from respective sides of the function block 3 and the X-direction wiring pattern 6 by a spacing d, to from approximated microisland patterns 9a-11a. Then, when the microisland patterns 9a-11a are enlarged into original sizes in the direction of the X-direction wiring pattern 6 and the block 3 facing each other, enlarged island patterns 9b-11b shown in a chain line can be formed while the form is maintained.

Title: Steering device for car
Inventor: MIYOSHI AKIHIKO
IPC: B62D1/16
Filed: 1985-07-22
Abstract: PURPOSE:To make small the extent of steering handle operation in a high speed range with a control device disordered without impairing the response and the follow-up quality of a steering handle in a slow speed range, by changing the control speed for a transmission ratio of a wheel steering angle to a steering wheel angle, according to car speed. CONSTITUTION:A variable means 9 for a transmission ratio is provided in way of a steering power transmission circuit in order to change a transmission ratio of a wheel steering angle thetaW to a steering angle thetaH, comprising planetary gears, differential gears and a step motor for the control thereof. Furthermore, car speed is detected by a car speed sensor 31 and transmission ratio control speed is made to change by a controller 33, according to a car speed rise. Consequently, the turning amount of a steering handle in a high speed range can be controlled at a small level, even when a time lag, if any, for detecting the irregular and disordered operation of the controller 33 is constant. On the other hand, in a slow speed range, it is possible to improve the response and the follow-up of wheel steering to the steering handle operation, with transmission ratio control speed kept at a high level.

Filed: 1980-11-17
Abstract: PURPOSE:To eliminate the need for an exclusive auxiliary power supply circuit and accordingly to avoid the loss of electric power, by receiving the electric power from an input power supply during starting and from a voltage converting circuit during stable working respectively for the auxiliary power supply for an output controlling circuit. CONSTITUTION:When the input power supply voltage V1 is supplied between input terminals 1 and 2, the voltage lower than a prescribed level is applied to an auxiliary power supply terminal 11 of a controlling circuit 6 since an intermediate terminal 10 of a voltage converting circuit 7' receives no application of the voltage of a prescribed level at first. Then the circuit 6 starts to control the circuit 7', and the circuit 7' has the steady working. Thus the voltage of a prescribed level is applied to the terminal 10. As a result, the voltage of a prescribed level is applied to the terminal 11 via a diode 9, and a diode 8 is interrupted. After this, the circuit 6 continues the steady control operation, and the circuit 7' transmits the stable output voltage V2 between an output power supply terminals 3 and 4.

Abstract: PURPOSE:To control directly the speed of an input device by reference to the movement of a mouse cursor by using a display device which shows the ratio of shift distance between a mouse and the mouse cursor and a mouse cursor moving speed changing device which changes the moving speed of the mouse cursor independently of the mouse. CONSTITUTION:A mouse cursor moving speed changing device 3 changes the shift ratio of distance between a mouse 2 and a mouse cursor on a display screen of a display device 1. The shift distance of the mouse cursor is decided by the set value of the device 3 against the shift distance of the mouse 2. Thus the moving speed of the mouse cursor is changed independently of the device 1 and the mouse 2. As a result, the moving speed of the mouse cursor can be freely controlled directly in reference to the movement of the mouse cursor or in accordance with the mouse operating state.

Abstract: PURPOSE:To decrease birefringent index and to make red not appear even at low temperature by making a liquid crystal layer less in thickness at its outer peripheral part than at its display part. CONSTITUTION:Electrode layers 12a and 12b and orientation layers 13a and 13b are arranged on the surfaces of substrates 11a and 11b made of glass, plastic, etc. The couple of substrates 11a and 11b are arranged so that the orientation film surfaces face each other. Glass fiber pieces 15a and 15b are incorporated in scaling agents 14a and 14b for charging liquid crystal and the agents are stuck on the substrates by screen printing or by using a dispenser. In this case, the liquid crystal layer is uniform at the display part because of the scattering of many spherical powder, but there is a little spherical powder at a non-display part, so the liquid crystal is not held uniform and the non- display part becomes darker than the display part. Further, when the diameters of the glass fiber pieces 15a and 15b are made smaller than the spherical power between the substrates, the liquid crystal layer is made less in thickness at the outer peripheral part.
