Abstract: PURPOSE:To enable a reduction/magnification rate suitable for required size to be read rapidly by a method wherein a diagram showing size and reduction/magnification rate is formed on a ruler wherein a standard size scale is put on a base line of the diagram and a plurality of proportional lines which cross respective parallel lines are provided corresponding to the scale. CONSTITUTION:A diagram B is provided on a transparent plastic ruler A. On said diagram B, a horizontal axis refers to size, and a vertical axis refers to reduction/ magnification rate, and % indicating lines Ba are provided in parallel with the horizontal axis with constant intervals parallel to one another, and one of them at the middle portion is specified to be a base line Bao with reduction/magnification rate of 100%. With reference to said line Bao, other parallel lines are provided with % indications of the reduction/magnification rate sequentially. The base line Bao is equipped with a standard size scale in cm units, and proportional lines Bb are provided which cross the respective parallel lines corresponding to the scale. When reduction rate of a drawing for example is to be obtained, the size of the drawing is measured on the base line, and the % indication line corresponding to the required reduction size is selected and read out by proceeding along the proportional line corresponding to the measured scale.

IPC: B62D7/14
Filed: 1985-10-01
Abstract: PURPOSE:To make possible to continue the control of a vehicle in safety, by automatically returning rear wheels to their neutral positions to allow the vehicle to be set into a front wheel steering condition when a rear steering mechanism falls into an uncontrollable condition due to a malfunction of a stepping motor. CONSTITUTION:The rotation of a stepping motor 12 is controlled in accordance with a desired rear wheel steering angle which is set in accordance with a steering ratio corresponding to a signal from a vehicle speed sensor 27 and a front wheel steering signal from a front wheel steering angle sensor 26. At this time, whether the stepping motor 12 is set at a limited rotational speed position or not is determined in accordance with a signal from a rotating angle sensor 40. If it is set a position other than a predetermined position, a power source for a stepping motor drive circuit 28 is deenergized and a control signal is delivered to solenoids 37, 38 in order to change over both first and second selector valves 31, 32 to their second positions where both valves 31, 32 are communicated with a hydraulic actuator 22. With this arrangement, the rear wheel 21 is returned to a neutral position so that the vehicle is set into a front wheel steering condition.

Abstract: PURPOSE:To prevent a face profile from deflecting and improve finishing accuracy in a valve as well as to make a dressing period for a grinding wheel prolongable, by applying a swivel-free type jig to the surface of a head part of the valve with constant pressure, during valve grinding. CONSTITUTION:At the grinding of a face profile of an engine valve 1, this engine valve 1 is rotated after clamping its valve stem part with a rotary chuck, while with a swivel-free type jig 3, a neck part 3b is applied, with constant pressure, to a head part surface 1b of the valve and supported thereon, and a grindstone 4 is applied to a face profile 1c whereby grinding takes place. During operation, deflection of the valve face profile of the engine valve is checked by the neck part 3b of the jig to be rotated together as it is pressed to a surface of the head part. Thus, the deflection and vibration in the head part of the valve is sharply reducible, therefore finishing accuracy on the valve face profile is improved and, what is more, an interval of wheel dressing periods is prolongable.

Title: Timepiece for blind
Inventor: FUJITA MASANORI
IPC: G04C3/14
Filed: 1982-12-16
Abstract: PURPOSE:To make a clock convenient when a user rides a vehicle by storing the time which is a prescribed time before the current time and informing the stored time to narrow an error range and, especially, lessen. CONSTITUTION:When a lock switch SW is opened, the reset of a frequency divider is released, and one pulse is generated from a terminal (m) to count up contents of a time counting circuit CT by one minute. If the switch SW is closed when the user wants to get the time, the contents of the circuit CT are latched in a latch circuit L. The number of informing signal corresponding to an hour and a minute of the time latched in the latch circuit L is generated from a informing circuit A and is informed by a speaker SP. That is, the time which is one minute before the current time is informed. For example, if 10:11 is latched at 10:10, informing tone of the hour and the minute is generated to inform the time; and since the intervals of generation of informing tones is set with a certain degree of margin, the error is reduced when the latched time is one minute before the current time.

The incident light on an LCD is given the double refraction meeting two-dimensional images by the pixels two-dimensionally arranged within the x-y plane and is transmitted through the polarizing plate, thereby, the light is converted into the light intensity distribution, i.e., the two-dimensional image. Of the light transmitted through the LCD, only the light within the LCD side NA (the numerical aperture determined by the incident pupil and focal length of the optical system) is introduced to the eyes.
