Title: Installing structure of leaf spring
Inventor: MAKINO MORITAKA
IPC: B60K20/06
Filed: 1995-06-05
Abstract: PURPOSE: To provide an installing structure of a leaf spring whose manufacturing efficiency can be increased by simplifying installing work of the leaf spring without impairing installing reliablity. CONSTITUTION: A shape of an under surface of a leaf spring pressing-down member 1Ob is formed so that its upper surface and the whole surface contact with each other at maximum deformation of a moderating leaf spring 120, and is formed so that about half of the under surface of the leaf spring pressing- down member l0b contacts with an upper surface of the moderating leaf spring 120 even at minimum deformation time of the moderating leaf spring 120. Therefore, a part of force applied in the upward direction by deformation of the moderating leaf spring 120 is always received by the under surface of the leaf spring pressing-down member 10b. Therefore, excessive force is not applied to a tapping screw 126 differently from a technology by which this force is all received by a screw fixing part.  As a result, even in a structure of being only fastened to a resinous leaf spring installing part 10 by the tapping screw 126, the screw fixing part does not float upward, and can sufficiently endure long-term use.

Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To provide a diagonal pouch including a standing pouch, and efficiently manufacture these pouch by inclining right and left by a specified angular range from the initial position when a top side of the pouch whose four corners form right angles is moved to a bottom side in the plan view of a bag-making condition. SOLUTION: A diagonal pouch 1 is a parallelogram in shape in which a top side of the diagonal pouch 1 square in plan view is shifted in the right-to-left direction with respect to a bottom side, and the angle θ of inclination of each side is set to 5-45 deg.. When the angle θ of inclination is below 5 deg., the appearance as the diagonal pouch 1 is not characterized, or the effect of easy pouring is not demonstrated. On the other hand, if the angle θof inclination exceeds 45 deg., the self-standing property of the diagonal pouch 1 is damaged. A specified radius, i.e., roundness 12 is formed on four corners of the diagonal pouch 1. In addition, an easily tearable part 9 is arranged on an upper end acute angle part side of the diagonal pouch, and a notch 10 of a specified shape is formed to easily unseal an opening part 8.

Title: Reflex projecting screen
Inventor: YATABE YOSHIO
IPC: G03B21/602
Filed: 1985-06-25
Abstract: PURPOSE:To eliminate the insufficiency of contrast in a dark part by providing the visual field lens of a convergence optical system on the front, a reflex lenticular lens on the back and a transparent optical medium with a high refraction factor between former two. CONSTITUTION:A lenticular lens surface 3 equipped with the refraction surface 1 of the visual field lens of the convergence optical system on the front and a reflex layer 2 on the back is provided, and the transparent optical medium 4 with a high refraction factor is filled in an intermediate space constructed with both lens surfaces. Thus the forward space on the reflex surface is filled with the transparent material with a high temperature refraction factor, and therefore the inclination of an incident beam develops a change in a direction of an angle twice said incline angle when the beam is made obliquely incident. The beam turns out to be a beam having the incident angle twice its initial one, again is made incident in the direction reverse to its initial one, and has a larger refraction angle than the incident angle due to the reaction of refraction when said beam enters air with a refraction factor of '1' from the optical material with a high refraction factor. Then the direction of said beam is further changed. Thus the projecting screen of an intensive light system can be obtained due to a high efficiency in terms of using a projected flux.
