Abstract: Provided is a taper reamer with which it is possible to achieve an improvement in machining accuracy and machining life. The taper reamer comprises a plurality of cutting edges each having a helical shape provided on the outer periphery of a cutting-edge portion having an external diameter being expanded from a front end toward a rear end thereof, wherein an intertooth angle, defined between each of a pair of the cutting edges adjacently arranged in a circumferential direction, is different from one another at any given reference position, and wherein the plurality of cutting edges each have a helix angle that is different from one another. As the plurality of cutting edges that are unequally partitioned each have the helix angle that is different from one another, a resonance during cutting can be prevented.

Abstract: A basic cylinder-charged air quantity is determined by a first-order delay processing of an intake air quantity per rotation. Next, an estimated value of a change portion of the cylinder-charged air quantity caused by a change in intake valve timing is computed on the basis of engine speed, throttle opening angle, displacement angle of the intake valve timing. Then, the estimated value of the change portion of the cylinder-charged air quantity is processed second-time by the first-order delay. A difference between the estimated value of a change portion of the cylinder-charged air quantity and a value obtained by processing the estimated value second-time by the first-order delay is added as a delay correction to the basic cylinder-charged air quantity, thereby obtaining an actual cylinder-charged air quantity with a change in the intake valve timing.

Abstract: Method for producing a of a transparent type hologram screen of an wide visible range. A photosensitive member and a light source of a reference light are arranged on the same side of the light diffusing body. A light source of an object light is arranged on the opposite side of the light diffusing body, so that the light is transmitted through the light diffusing body to generate a object light. A light from a light source of a reference light is reflected at the light diffusing body or a member such as a half mirror or a transparent, reflective hologram element arranged at a front side of the light diffusing body.

Abstract: A method of producing a holographic optical element which is capable of imparting complex corrections to the holographic optical element and of effecting the exposure using a short optical path permitting little disturbance to be infiltrated. A correction holographic optical element 13 for correcting the characteristics of the holographic optical element is disposed in at least one of the optical paths of an object beam 35 and a reference beam 36 that fall on a photosensitive material 11. The object beam 35 may be one obtained by reflecting the reference beam 36 by a reflection-type holographic optical element such as a reflection-type master holographic optical element 12. In the case of a holographic optical element used for the head-up display, the correction holographic optical element 13 may be given characteristics for correcting the curvature of the windshield or characteristics for correcting color aberration.

Abstract: A heads-up display unit provided with a display device serving as display image forming means which displays a display image. A hologram serves as a reflecting means, and reflects the display light emitted from the display device, causing reflection of the display image on the interior surface of a vehicle's windshield. A display image is formed outside the windshield towards the front of the vehicle. A concave mirror having a different focal length in different directions is recorded in the hologram serving as a reflecting means so as to offset distortion of the display image caused by curvatures of the windshield. This construction makes it possible to cause the windshield to display a display image free from distortion.
